Tree ring analysis involves examining the growth rings of trees. Each year a tree forms a new growth ring, with wider rings indicating better growing conditions and narrower rings indicating drought or other environmental stressors. Scientists can use patterns in tree ring widths to date samples very precisely by year. Dendrochronology, the scientific study of tree ring patterns, helps researchers understand past climates and date archaeological sites by matching ring patterns among trees.

GEOG5839.01. Introduction to Dendrochronology
Tree rings tell us much more than just a tree’s age. They also provide clues that help us understand how our environment has changed in the past, and provide insights into how key processes in atmosphere, biosphere and geological systems operate over long timescales.
Class 1, introduction to dendrochronology
The annual growth rings from trees provide us with an incredibly powerful and adaptable tool to study Earth’s history. The rings tell us much more than just the age of tree. They also provide clues that help us understand how our environment has changed in the past, and provide insights into how key processes in atmosphere, biosphere and geological systems operate over long timescales.
This course will teach students the fundamental principles of dendrochronology through a combination of formal lectures, class discussion and laboratory exercises. Students will work in the University of Minnesota’s Center for Dendrochronology, where they will learn how to collect, prepare and date tree-ring specimens. By the end of the course, they will be able to explain both the key concepts underlying dendrochronology and discuss how evidence from tree rings is used to address contemporary issues in natural history, resource management and Earth Systems Science.
plant succession
This document provides information about plant succession over multiple pages. It begins with definitions and history, describing succession as the directional change in plant species occupying an area over time. It then describes different types of succession (primary, secondary, etc.), stages of hydrosere and xerosere successions, and trends during succession like increasing complexity and biomass. The document outlines the process of succession and concludes by discussing climatic, topographic, and biotic causes that can initiate succession.
tree ring analysis
Tree rings can be used to determine the age of trees and study environmental conditions in different years. Each year a tree forms a new growth ring, with wider rings indicating better growing conditions and narrower rings indicating drought or other difficulties. By matching ring patterns between trees, scientists have developed tree-ring chronologies that can date back thousands of years. The field of dendrochronology uses these ring patterns to date wood and study past climate patterns, as well as applications in archaeology, geology, and environmental science.
Diatom - Overview
Diatoms are a major group of algae that are commonly found as phytoplankton. They have skeletons made of silica coated with organic material that come in a wide diversity of shapes, either radially or bilaterally symmetrical. Diatoms reproduce asexually through binary fission, where each daughter cell receives one of the parent's frustules and builds a new smaller one, causing population size reduction over time. To counter this, sexual reproduction through meiosis and fusion of gametes occurs, forming a large auxospore that grows into a maximum-sized new initial cell to start the next generation.
Annual ring and wood
1. Annual rings in plants are formed due to seasonal variations in the activity of vascular cambium. Spring wood formed during periods of high cambium activity is lighter in color and more porous than autumn wood.
2. One annual ring is formed each year, consisting of one ring of spring wood and one of autumn wood. Counting the number of annual rings can determine the age of the tree.
3. Annual rings are most distinct in temperate deciduous trees, and least distinct in tropical plants and trees near the seashore with constant climates.
Dendrochronology jaspreet
Dendrochronology is the study of tree rings to determine a tree's age and learn about past climate conditions. It works by matching patterns of wide and narrow tree rings between core samples from the same tree and across different trees. This technique, called crossdating, allows scientists to assign exact years to each tree ring. Dendrochronology reveals that tree growth and ring patterns correlate with climate - trees grow better rings in warm, wet conditions and poorer rings when cold and dry. Only trees in temperate zones exhibit clear annual growth rings due to seasonal climate changes.

Climatic factors
This document discusses plant ecology and environmental factors that influence plants. It covers several climatic and edaphic factors including light, temperature, water, and soil properties.
Light is the main source of energy for photosynthesis. Intensity of light varies based on location and can influence plant structure, physiology, growth, and distribution. Temperature also varies spatially and can affect plant metabolism, reproduction, and tolerance ranges. Water is essential for plant biological processes and its physical properties like surface tension and cohesion influence plant water transport. Soil properties like composition and erosion impact plant nutrition and growth.

Forest succession and stages ppt
Ecological succession describes the natural process of environmental change through which the species composition of an area evolves over time. Primary succession begins from abiotic conditions like newly exposed rock, while secondary succession follows disturbances that remove existing life but leave soil intact. Succession proceeds through stages as pioneer species establish and modify conditions, allowing more complex plants and wildlife to gradually occupy the area until a climax community develops. Forest succession in Oregon moves from lichen and moss pioneers to shrub, young forest, mature forest, and finally climax stages dominated by species like hemlock, pine and fir.
Cyclones and anticyclones
Cyclones involve a closed circulation around a low pressure center, spinning counterclockwise in the Northern Hemisphere. They bring strong winds inward and cause extensive damage from heavy rain. Cyclones are known by different names depending on location, such as hurricanes in the Atlantic and typhoons in the Western Pacific. Anticyclones circulate clockwise around a high pressure center, pushing winds outward and typically bringing fine weather. Key differences between cyclones and anticyclones are the direction of circulation and associated weather patterns.
Swamps
Swamps are wetlands that are forested or dominated by shrubs. They occur along rivers and lakes where water levels are dependent on natural flows. Swamps support a variety of plant and animal life, including trees like bald cypress and tupelo gum, shrubs, fish, alligators, birds, and insects. Swamps can also contain dry-land areas called hammocks covered in aquatic or periodically flooded vegetation.

ROLE OF PALYNOLOGY IN PALEOPALYNOLOGY.pptx
This document discusses the role of palynology in paleopalynology and hydrocarbon exploration. It begins with introductions to palynology and paleopalynology, and describes methods used in paleopalynology such as sample collection, extraction, mounting, and analysis. It outlines applications of paleopalynology including tracing vegetation history, correlating deposits, and studying climate change. The document also discusses the use of microfossils like pollen in fossil fuel exploration and the formation of petroleum and natural gas. It concludes that palynology is an essential tool for studying sediments and rocks in contexts like biostratigraphy, paleoenvironmental analysis, and characterizing rocks for hydrocarbon content.
Abscission
Abscission is the process by which plant organs such as leaves, flowers, and fruits become detached from the plant in a controlled manner. It occurs through the formation of an abscission zone, a layer of weak-walled cells located at the base of the petiole or other structure. Abscission is controlled by the plant hormones auxin and ethylene, with decreasing auxin and increasing ethylene levels initiating cell wall degradation in the abscission zone. This allows separation of plant organs through a combination of enzymatic breakdown and mechanical forces. Abscission aids in shedding organs no longer needed by the plant and occurs in response to environmental and developmental signals.

Precipitation, types and their different forms.
This document discusses different types of precipitation including rain, snow, hail, sleet and drizzle. It explains that precipitation forms through the process of evaporation, cooling, condensation and growth of water droplets. There are three main types of precipitation: convective caused by warm air rising, orographic caused when air is forced up over mountains, and cyclonic caused by interactions of warm and cold air masses. The document provides details on the formation mechanisms and characteristics of various precipitation types.
The Desert Biome
Deserts cover about one-fifth of the Earth's land surface and are typically found near the Tropics or in places like the southwest US, South America, Africa, Australia and the Middle East. Deserts receive less than 30cm of rain annually and have hot days and cold nights. Plants in deserts are scattered and adapted to store water, like cacti, while animals are nocturnal and burrow underground or are adapted to limited water intake. Some common desert plants and animals include various cacti, bushes, coyotes, kangaroo rats and tortoises.
Sciophytes
Sciophytes, or shade-loving plants, have developed several anatomical, morphological, and physiological adaptations to low light conditions. They tend to have larger, thinner leaves with more chlorophyll to maximize light absorption. Their foliage often remains evergreen to capture light during winter. Sciophytes generally prefer acid, organic-rich soil and can be found in humid or poorly drained areas. While some tolerate only full shade, others need some sun to flower but perform best in partial shade. Their adaptations allow sciophytes to efficiently utilize the limited sunlight available on forest floors.
Classification of algae
Lee (1999) classified algae into four groups based on the structure of their chloroplasts. Group 1 contains cyanobacteria, which have prokaryotic cells. Group 2 algae have chloroplasts surrounded by two chloroplast envelope membranes. Group 3 algae have chloroplasts surrounded by a single membrane. Group 4 algae have chloroplasts surrounded by two membranes continuous with the endoplasmic reticulum. The document then discusses the taxonomic classification system used for algae and provides characteristic features of different algal groups.

Palynology pollen morphology and biology
The document discusses how palynology, the study of pollen grains and spores, can provide taxonomic evidence for classifying plants. It outlines several palynological features that can be used in plant systematics, including pollen nucleus number, storage product, unit, polarity, aperture, size, shape, sculpturing, and wall structure. These features vary across plant taxa and families, providing a basis for identification and analysis of phylogenetic relationships.
Classification of pollen and spores
This document discusses spores and pollen classification using the Numerical Palynological Classification (NPC) system. It describes how NPC classifies pollen and spores based on their aperture number, position, and character. The document outlines the merits of NPC as a simple and consistent classification system that allows for differentiation of plant groups. However, it also notes NPC is an artificial system and has limitations for types of pollen that do not fit its structure.
water, temperature and wind factor
The document discusses various factors related to water and temperature and their impact on plants. It describes the water cycle and key processes like precipitation, infiltration, evaporation. It discusses plant adaptations to drought like reduced leaf area and deep roots. It also covers temperature as an ecological factor, explaining how it affects plant growth, metabolism and distribution. Plants have developed adaptations to temperature extremes like dormancy, small leaves and high osmotic concentrations to resist freezing.
GEOG5839.19, Dendroclimatology
This document discusses tree ring dendroclimatology and how tree ring records can be used to understand past climates. Tree ring growth is influenced by climate factors like temperature and precipitation. Multiple tree ring records from a region can be combined and correlated with observed climate data to develop climate reconstructions spanning centuries. However, tree ring growth can be affected by non-climatic factors as well, and some recent studies have found a divergence or weakening correlation between tree growth and temperatures in some northern sites. Overall, tree ring records are a valuable but imperfect proxy for understanding past climate variability over centuries to millennia when used carefully.
Structure of Anther
This document discusses the structure and development of the anther wall in flowering plants. It notes that the anther wall consists of four layers - epidermis, endothecium, middle layers, and tapetum. The tapetum is the innermost layer and completely surrounds the sporogenous tissue. It transports nutrients to developing spores and is involved in exine formation, either through amoeboid intrusion into the anther locule or secretion of substances. The document provides details on the structure and function of each anther wall layer.
Dendrochronology pow pt acloutier 2012
Dendrochronology is the science of studying tree growth rings to determine past environmental conditions. Trees record information about forest fires, floods, droughts, meteorite strikes, volcanic eruptions, and ice ages in their growth rings. By examining a tree's core sample or cut-down tree, scientists can see the tree's life and evidence of climate changes, fires, and variations in sunlight intensity over time. Trees need sunlight, water, minerals, and the right temperature conditions to grow and produce growth rings through photosynthesis, cell meiosis, cell mitosis, and water-based cell division and multiplication processes.
Building tree-ring chronologies and Program ARSTAN
The document discusses dendroclimatology and paleoclimatology, including how tree rings can be used as climate proxies to reconstruct past climate variations. It explains how tree-ring measurements are standardized and aggregated to extract climate signals and maximize the environmental information while minimizing noise. Methods like COFECHA, detrending, and ARSTAN are used to process tree-ring data and develop high-quality tree-ring chronologies suitable for climate reconstruction.

GEOG5839.06, The principle of cross dating
The document discusses the principle of cross-dating tree rings. [1] Cross-dating involves matching patterns in tree ring widths or characteristics among multiple trees to identify the exact year each ring was formed. [2] This allows scientists to synchronize the tree ring chronologies and date wood samples far into the past without relying solely on ring counting. [3] Cross-dating is essential for dendrochronology because of various complications that can occur with tree ring formation.
GEOG5839.14, The history of dendrochronology
This document provides a brief history of dendrochronology, or tree-ring dating. It traces the field back to early observations by Leonardo da Vinci and Theophrastus on tree growth patterns. Several 18th century scientists like Duhamel du Monceau and Buffon made further contributions. Andrew Ellicott Douglass, considered the founder of the modern field of dendrochronology, developed the technique of cross-dating tree rings in the early 20th century. This allowed the calibration of floating tree-ring chronologies to calendar years and the dating of archaeological sites and ruins in the American Southwest.

Radiation hazards
Radiation is energy transmitted through space or matter in the form of waves or particles. It includes visible light, ultraviolet light from the sun, and radio/TV signals. Nuclear radiation comes from unstable atoms undergoing radioactive decay, emitting particles like alpha and beta or electromagnetic waves like gamma rays. Exposure to ionizing radiation can damage living tissue. Natural sources of radiation include cosmic rays, radioactive elements in the earth's crust like radon, and some food/drink. Medical procedures and occupational exposures also contribute. In materials, radiation can cause impurities from nuclear reactions, ionization by charged particles, and displacement of atoms from their normal positions in the crystal structure.
Health Effects Of Radiation Exposure
The document discusses the health effects of radiation exposure. It provides an overview of radiation sources and the types of radiation. Ionizing radiation can damage DNA and lead to cancer or other health issues. The risk of cancer increases with higher radiation exposure but some risk exists even at low doses according to linear no-threshold models. Medical imaging is a major source of radiation exposure from diagnostic tests like CT scans.
Biological effects of radiation
This document provides an overview of radiobiology and radiation biology. It begins by defining radiobiology as the study of the effects of ionizing radiation on living systems. It then discusses the initial interactions of radiation with matter on an atomic level and how this can lead to molecular changes in cells and organisms over time, potentially resulting in injury or death. The document further explores the composition of matter, types of radiation including ionizing and non-ionizing radiation, radiation measurements, and concepts such as linear energy transfer and relative biological effectiveness. It also examines the sequence of radiation injury and key related terms.
Radiation hazards
The document discusses the health effects of radiation exposure, including radiation sickness caused by changes to living tissues, as well as somatic and genetic effects. It describes the mechanisms by which ionizing radiation interacts with and damages biological molecules and cells, leading to both acute and long-term health consequences like cancer and genetic mutations. Guidelines are provided for radiation safety and protection measures to minimize exposure when working with radiation sources.

This study investigated how different levels of canopy cover influence understory vegetation in Mazumbai Forest Reserve in Tanzania. The researcher recorded vegetation data in plots under three canopy cover levels: 0-33%, 33-67%, and 67-100%. It was predicted that plots under 33-67% canopy would have the greatest diversity and coverage, while those under 67-100% canopy would have the least. The results found that plots under 0-33% canopy had the most species variety, while those under 33-67% canopy had the least. There were no significant differences in grass, herb, or shrub coverage between canopy levels. Tree coverage was significantly different, with the most trees under 67-100% canopy and the few

- The document analyzes growth patterns of black spruce trees in a central Maine peat bog to understand relationships between tree growth, climate, and distance from the bog edge.
- Tree cores were collected from black spruce trees along three transects at increasing distances from the bog edge. Tree and stand characteristics, growth rates, and influence of climate factors like temperature and precipitation were analyzed.
- Preliminary results suggest that tree growth rates increased with distance from the bog edge likely due to higher nutrient availability further from the bog. Climate accounted for only small variations in growth, with temperature having a greater influence than precipitation.

range where timber has gotten to be and stays wet. Indications of wet decay :
Mutilation, discolouration, non-abrasiveness and breaking
Loss of quality to the timber
Noticeable contagious development – this may now and again happen
Smell – there might be a soggy smelly smell
Flare-ups of dry and wet decay begin in comparative ways. The develop fruiting assortments of
wood-annihilating organisms that create amid an assault deliver a large number of tiny spores
and these are generally scattered via air streams. In the event that they fall on untreated moist
wood they will develop by pushing out an empty tube called a hypha which develops and
branches to frame a mass of hyphal strings called mycelium.
The principle contrasts between dry year and wet year are the level of advancement of mycelium
on the wood surface and the capacity of the organism to spread into different timbers by means
of nearby brick work. It is imperative that the two sorts of rot be recognized since they require
distinctive treatment.
Part3
Dendrochronology is the investigation of environmental change as recorded by tree development
rings. Every year, trees include a layer of development between the more established wood and
the bark. This layer, or ring as found in cross segment, can be wide, recording a wet season, or
thin, recording a dry developing season. Since the rings are essentially recording a decent
developing season or a terrible developing season, they are in a roundabout way recording more
than just dampness. They likewise record temperature and overcast cover as they effect tree
development too. This record of yearly summer data is imperative when you consider that
specific sorts of trees develop gradually over several years, and subsequently contain a record of
the same number of years of atmosphere and environmental change..
Trees and their role in water management
Trees provide numerous environmental benefits by moderating climate, improving air quality, conserving water, and providing habitat for wildlife. They alter the environment through climate control by moderating the effects of sun, wind, and rain. Trees also improve air quality by filtering pollutants and absorbing carbon dioxide and other gases. Planting trees helps manage stormwater runoff and reduces flooding by intercepting rainfall and allowing more water to infiltrate into the soil.
GEOG3839.16, Dendroecology
Dendroecology is the use of tree-ring dating and analyses to investigate events and processes involving the interactions of organisms with their environment. It provides a longer temporal perspective than other records through tree-ring evidence that has high precision. Chronological control allows comparison of multiple lines of evidence. However, tree-ring records can be irregular and some processes may be unknown. Past conditions may have no modern analog, complicating interpretation. Dendroecology is used to study forest demography, growth dynamics, and disturbance ecology like insect outbreaks and fire history.
Deciduous biome
The document provides information about the temperate deciduous forest biome. It describes the canopy layer of tall trees, leaf litter on the forest floor, and thick layer of nutrient-rich soil created by decomposition. It discusses the characteristics of deciduous trees, examples of which include oaks, maples and fruit trees. The document outlines the location of deciduous forests globally and describes the four distinct seasons and average temperature and precipitation in these regions. It examines the plant and animal adaptations for survival and lists common species found in temperate deciduous forests. In closing, it discusses threats to these forests from human activities like acid rain, deforestation and invasive species, as well as conservation efforts.
Ecosystem
This document discusses ecosystems and their conservation. It begins by defining an ecosystem as an area composed of biotic and abiotic factors that includes a biological community and its physical environment. It then discusses the importance of conserving ecosystems and biodiversity, as well as some of the threats they face from human activities and natural calamities. The document provides information on different types of ecosystems like forests, deserts, grasslands, and aquatic ecosystems. It highlights the roles of ecosystems and the need for their conservation.
Harsh singh

It also describes the ozone layer and how it protects the surface from UV radiation. Additionally, it covers geological activity like plate tectonics and volcanoes. Biomes and biogeochemical cycles are defined. Wilderness areas and weather phenomena are also summarized. Ecosystems are described as natural units consisting of biotic and abiotic factors that interact within a defined area. Biodiversity can contribute to an ecosystem's resilience to change.
A Guide to Nurturing Trees Through Changing Seasons.pdf
In the delicate tapestry of the natural world, trees stand as steadfast sentinels, bridging the gap between earth and sky. Their perennial presence is a testament to the unyielding resilience of life, gracefully adapting to the rhythm of changing seasons. As the world around us transforms with each passing month, trees undergo an intricate dance of growth, rest, and rebirth, mirroring the cycle of life itself.
Literature_Overview_Thom_Erritt (1)
The document is a 4975 word literature review written by Thom Erritt for his supervisor Dr. Jane Memmott at the University of Bristol. The review examines whether veteran trees are used disproportionately more by local wildlife than surrounding non-veteran trees. It begins by defining veteran trees and describing their key characteristics. It then discusses how trees age and develop over time. The review also covers why veteran trees are valuable and warrant conservation efforts. Finally, it looks at specific interactions between veteran trees and local wildlife, particularly the role of deadwood. The goal is to provide context and background information to help interpret the results of Thom's research project comparing wildlife usage of veteran and non-veteran trees.

Terretrial Ecosystem.pdf
1. Terrestrial environments can be characterized by their vegetation like forests, grasslands, and shrublands, as well as their physical and chemical properties like soil.
2. Soil provides the foundation for plant growth and serves as a habitat for animals and a system to break down waste.
3. Biomes are large regions defined by their dominant plant life and climate. Major terrestrial biomes include tropical forests, temperate forests, conifer forests, tropical savannas, temperate grasslands, shrublands, tundra, and deserts.
What is ecology
1) An ecosystem consists of all the living organisms (biotic factors) in a particular area, along with the nonliving (abiotic) parts like air, water, and mineral resources.
2) Primary succession occurs in new areas like land exposed by retreating glaciers, where pioneer species arrive first and help create conditions for later species.
3) Secondary succession follows disruptions to existing ecosystems, as earlier species are replaced over time, progressing towards a stable climactic community composition.
Paleoclimatology
Paleoclimatology is the study of past climates using natural evidence, or proxies, left in tree rings, ice cores, pollen, and sediments. Scientists use tree ring analysis to determine past climate conditions from tree growth patterns. Pollen analysis identifies past vegetation by analyzing fossilized pollen grains. Isotope analysis of oxygen in fossils, ice cores, and sediments provides clues about past temperatures and ocean conditions. Current melting of sea ice and rising sea levels indicate warming may disrupt ocean circulation as seen in prior interglacial periods.
Landscape notes
This document provides information on three topics: terrace gardens, the role of trees in urban environments, and site analysis in landscape design.
Regarding terrace gardens, the document discusses how they can be used in urban areas with limited space, such as on rooftops or patios. It also describes how terrace gardens are constructed on hillsides using retaining walls. The document notes factors to consider when establishing a terrace garden like sun exposure, access to water, and the intended use.
For the role of trees in urban environments, the document outlines benefits like improved air quality, temperature regulation, and increased property values. It describes how trees reduce air pollution through absorption of carbon dioxide and particulate matter.
CBSE Class IX Chemistry Natural resources
This document provides information about various natural resources. It discusses key natural resources like water, air, plants, fossil fuels, rocks, minerals, forestry, soil, oceans, lakes, groundwater, and rivers. For each resource, it provides a brief definition and relevant details. It emphasizes that natural resources are extremely important for human survival and that we must work to save and conserve them.
ECOSYSTEM.pptx
An ecosystem consists of biotic and abiotic components that interact. Biotic components are living organisms like plants, animals and microbes. Abiotic components are non-living physical factors like soil, water, sunlight and temperature. Within an ecosystem, organisms fill different roles - producers generate food, consumers feed on other organisms or food, and decomposers break down dead matter. Ecosystems can vary in size from small like a puddle to very large like a desert, and are shaped by abiotic factors such as climate, physiographic features, and atmospheric gases.
Assessment of Biomass Content and Oxygen Production from Tree of Subtropical ...
The accurate classification of tree species is critical for the management of forest ecosystems, particularly subtropical forests, which are highly diverse and complex ecosystems. While airborne Light Detection and Ranging LiDAR technology offers significant potential to estimate forest structural attributes, the capacity of this new tool to classify species is less well known. In this research, full waveform metrics were extracted by a voxel based composite waveform approach and examined with a Random Forests classifier to discriminate six subtropical tree species i.e., Masson pine Pinus massoniana Lamb. , Chinese fir Cunninghamia lanceolata Lamb. Hook. , Slash pines Pinus elliottii Engelm. , Sawtooth oak Quercus acutissima Carruth. and Chinese holly Ilex chinensis Sims. at three levels of discrimination. As part of the analysis, the optimal voxel size for modelling the composite waveforms was investigated, the most important predictor metrics for species classification assessed and the effect of scan angle on species discrimination examined. Results demonstrate that all tree species were classified with relatively high accuracy 68.6 for six classes, 75.8 for four main species and 86.2 for conifers and broadleaved trees . Full waveform metrics based on height of median energy, waveform distance and number of waveform peaks demonstrated high classification importance and were stable among various voxel sizes. The results also suggest that the voxel based approach can alleviate some of the issues associated with large scan angles. Dr. Mahima Chaurasia | Er. Nidhi Prasad | Dr. Sanjeev Kumar Srivastava | Dr. Siddhartha Shukla "Assessment of Biomass Content and Oxygen Production from Tree of Subtropical Area" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-7 | Issue-1 , February 2023, URL: https://www.ijtsrd.com/papers/ijtsrd53842.pdf Paper URL: https://www.ijtsrd.com/other-scientific-research-area/other/53842/assessment-of-biomass-content-and-oxygen-production-from-tree-of-subtropical-area/dr-mahima-chaurasia

(Q)SAR Assessment Framework: Guidance for Assessing (Q)SAR Models and Predict...
The webinar provided an overview of the new OECD (Q)SAR Assessment Framework for evaluating the scientific validity of (Q)SAR models, predictions, and results from multiple predictions. The QAF provides assessment elements for existing principles for evaluating models, as well as new principles for evaluating predictions and results. In addition to the principles, assessment elements, and guidance for evaluating each element, the QAF includes a checklist for reporting assessments.
This new Framework provides regulators with a consistent and transparent approach for reviewing the use of (Q)SAR predictions in a regulatory context and increases the confidence to accept alternative methods for evaluating chemical hazards. The OECD worked closely together with the Istituto Superiore di Sanità (Italy) and the European Chemicals Agency (ECHA), supported by a variety of international experts to develop a checklist of criteria and guidance for evaluating each criterion. The aim of the QAF is to help establish confidence in the use of (Q)SARs in evaluating chemical safety, and was designed to be applicable irrespective of the modelling technique used to build the model, the predicted endpoint, and the intended regulatory purpose.
The webinar provided an overview of the project and presented the main aspects of the framework for assessing models and results based on individual or multiple predictions.

Monitor indicators of genetic diversity from space using Earth Observation data
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

tree ring analysis ( master chronology , Dendrochronology)
- 2. Each year, the tree forms new cells, arranged in concentric circles called annual rings or annual growth rings. These annual rings show the amount of wood produced during one growing season .
- 3. A cross section of a tree shows much more than its age! Diameter growth is particularly sensitive to fluctuations in the environment: 1. moisture in the soil and air 2. temperature 3. sunlight
- 4. Very broad rings generally indicate a good growing year.
- 5. Similar patterns occur in the rings of different tree species over a large geographic area due to variations in the amount of annual perception . Years in which adequate precipitation occurs produce wider rings of growth , but years of drought produce much narrower rings .
- 6. The inner portion of a growth ring is formed early in the growing season, when growth is comparatively rapid (hence the wood is less dense) and is known as “early wood”. The outer portion is the “late wood” (and has sometimes been termed “summer wood”, often being produced in the summer, though sometimes in the autumn) and is denser .
- 7. It is possible to study ring sequences that go back to several thousands years
- 8. 1.master chronology: An average tree-ring chronology for a particular region, or one derived locally from a number of closely matching individual tree-ring chronologies. The master chronology forms the reference against which new ring series may be compared and dated.
- 9. 2.Dendrochronology : (dendron= tree, chronos = time) is a scientific method that uses tree-ring sequences to date annual growth rings of plant to their exact year of formation. It is applied in several scientific fields, namely archaeology, climatology, geomorphology, glaciology, hydrology, fire history, entomology.
- 10. Dendrochronology it is the study of bot visible and microscopic details of tree rings. Uses : 1 tree ring analysis has been extremly useful in investigation of prehistoric sites of native Americans in the southeast 2.tree ring data are also useful in other disciptions including ecology to study changes in forest community over time 3. Environmental science to study the effects of air pollution on tree growth 4. ecology to date the earthquakes and volcanic eruptions
