The document discusses the importance of crop wild relatives (CWR) for adapting crops to climate change and other threats. It notes that CWR cover half the Earth's land and have provided genes for disease resistance and other traits. However, CWR populations are threatened by climate change and land use changes. The Global Crop Diversity Trust's CWR initiative aims to collect, conserve and use CWR diversity for climate change adaptation. It discusses challenges like identifying useful traits in wild species and removing undesirable linkages when introducing genes into crops. Genomics approaches may help address these challenges by discovering cryptic variation in CWR.

pre-AP Bio 5.2
This document discusses limiting factors that determine the carrying capacity of an environment for a species. It identifies factors that are density dependent, meaning they strongly affect populations when density reaches a certain level, such as competition for resources, predator-prey relationships, herbivore effects, and parasitism and disease. It also identifies density-independent factors that affect populations regardless of size or density, such as hurricanes, droughts, and wildfires. Examples are provided to illustrate both types of limiting factors.

Genetically Modified Organisms: Impact on Developing Nations
This document discusses genetically modified organisms (GMOs) and their potential impacts in developing nations. It notes that GMOs could help address food insecurity, protect the environment, and increase food production. However, it also raises concerns about increased agrochemical use, loss of biodiversity, and issues of social inequality. The document advocates for policies around GMOs in developing countries that focus on sustainability, biodiversity, local inputs, and farmer control and equality.
Partnering on CWR research at three scales: commonalities for success
The potential for crop wild relatives (CWR) to contribute to crop improvement is growing due to improvements in information on species and their diversity, advancements in breeding tools, and the growing need for exotic genetic diversity to address compounding agronomic challenges. As wild plants, CWR are subject to a myriad of human caused threats to natural ecosystems, and their representation ex situ is often far from comprehensive. Ex situ conservation of many of these wild plants is also technically challenging, particularly in an environment of insufficient resources. Enhancing conservation, availability, and access to CWR requires a spectrum of action spanning basic and applied research on wild species to inform on-the-ground collecting, ex situ maintenance, and germplasm utilization. The development of effective information channels and productive partnerships between diverse organizations are essential to the success of these actions. Here we report on a spectrum of CWR activities involving broad partnerships, at three levels: a) the collaborative compilation and distribution on over 5 million occurrence data records on the CWR of major food crops, b) the analysis of conservation concerns and genetic resources potential of the CWR of potato, sweetpotato, and pigeonpea, and c) ongoing efforts to map the diversity and conservation concerns for CWR in the USA. Although differing in scales and depth of collaborations, the success of these initiatives are largely due to commonalities in research orientation, e.g., inclusiveness, offering clear incentives for involvement, and service providing to the crop science community.
Genetic diversity in endangered organisms
Genetic diversity is important for endangered species survival. Low genetic diversity increases extinction risk as populations lose their ability to adapt. This document discusses how certain endangered species like macaws, pangolins and rafflesia flowers have low genetic diversity due to poaching and habitat loss, making them vulnerable. A genetic rescue experiment introduced new genes to the inbred Florida panther population, increasing genetic diversity and allowing the population to triple in size. Maintaining genetic diversity through conservation of habitats and populations is crucial for species survival.

Management of intra and inter specific genetic diversity
This document discusses genetic diversity and its conservation. It defines genetic diversity as variation at the genetic level among organisms of a species. Genetic diversity is important for species continuity and adaptation. There are two main types of genetic diversity - intraspecific (within species) and interspecific (between species). Methods to conserve genetic diversity include ex-situ conservation methods like cryopreservation, seed banks, and tissue culture as well as in-situ conservation methods like biosphere reserves and sacred groves. Case studies demonstrate successful cryopreservation of sweet potato shoot tips and protection of genetic resources in sacred groves in India. The conclusion emphasizes that diverse plant genetic resources are valuable and their conservation is essential for present and future human well-
02 domestication
This document discusses the process of plant domestication. It begins by defining domestication and explaining how early humans selected traits like large plant parts and thick flesh in domesticated food plants. It then provides details on the benefits of domestication, the five levels of domestication, and the domestication syndrome. The document also examines outstanding questions in domestication research and insights from archeological and genetic studies. Specifically, it notes how domestication traits are influenced by a small number of regulatory genes and allows for rapid evolution.

Genetic diversity is the variation of genes within and between populations of a species. It is important for species survival and adaptability. Loss of genetic diversity reduces a species' ability to adapt to environmental changes and increases risks of inbreeding, which can lead to extinction. Key causes of loss of diversity include habitat loss and degradation, pollution, monocultures in agriculture that replace diverse landraces and varieties, and overexploitation of wild species. Conservation aims to preserve natural patterns of genetic diversity to maintain options for future evolution. Loss of genetic diversity is potentially the most serious environmental problem because it cannot be reversed within just a few generations.
Participatory mapping for the systematic monitoring of biodiversity
Participatory mapping for the systematic monitoring of biodiversityCGIAR Research Program on Roots, Tubers and Bananas
Biodiversity sustains a wide variety of genetic traits that are very valuable for the potato's adaption to changing environments and successful cultivation in the future. However, several factors are threatening biodiversity in the Andes. For this reason, it is necessary for monitoring to be done with a standardized system and common observation parameters. Here we explain how participatory mapping and survey methods are used for the systematic monitoring of potato landraces in the Andes.Community seed banks and farmers’ rights
Bioversity International policy scientist Ronnie Vernooy gave this presentation at the the Global Consultation on Farmers’ Rights, Indonesia, 27-30 September 2016, organized by the International Treaty on Plant Genetic Resources for Food and Agriculture (Plant Treaty).
The importance of farmers’ rights is recognized in Article 9 of the Plant Treaty.
In this presentation Vernooy shows how a community-based approach to the management of agricultural biodiversity, including supporting community seedbanks, can empower and benefit smallholder farmers and farming communities economically, environmentally and socially. This approach makes implementing farmers’ rights at national level both practical and effective contributing to food and seed security, sustainable livelihoods and resilience.

Wildland Weeds article-KOI
The document summarizes exotic plant removal programs conducted at John Williams Park in Hollywood, Florida between 2006-2007. Key points:
- Volunteers from local environmental organizations led workshops to remove invasive plants like rosary pea, air potato, and Caesar's weed from the park. Hundreds of bags of exotics were removed.
- Additional programs targeted areas like the Sheridan Oaks Forest Natural Area that were overrun with invasive air potato.
- The efforts significantly reduced the exotic plant population and allowed native plants to recover without competition for space and resources.
Domestication And Evolution
A 50-year experiment on fox domestication was conducted in Novosibirsk, Russia beginning in 1959. The experiment aimed to study the genetic changes underlying animal domestication by selectively breeding foxes for tameness towards humans. Over generations, the foxes selected for friendliness developed morphological traits like floppy ears, curled tails, and spotted coats similar to dogs. The results supported the hypothesis that selection for a single regulatory trait like behavior can induce changes across the genome by destabilizing developmental processes. This provided insights into the genetic mechanisms and parallel changes seen during animal domestication.
Conservation Priorities for CWR in the United States
This document discusses conservation priorities for crop wild relatives in the United States. It provides an inventory of over 4,600 crop wild relatives taxa in the US, including the highest priority native relatives of 38 major food crops (250 taxa). The document analyzes gaps in conservation and recommends priority areas for further collecting of 219 wild relative species. It outlines ongoing conservation efforts like plant collecting initiatives and cooperation between the US Forest Service and USDA to establish in situ conservation areas for crop wild relatives on National Forest lands. The goal is comprehensive conservation of crop wild relatives nationally to ensure availability of genetic resources and meet global biodiversity targets.
Natural selection (2011)
This document summarizes the key components of biological evolution by natural selection:
1) Genetic variation within populations arises from mutations, gene flow, and sexual reproduction.
2) Variations must be heritable in order to be passed on to offspring.
3) Individuals with heritable traits that increase fitness, like survival and reproductive success, will pass their genes on more often.
4) Over time, natural selection leads populations to become better adapted to their environment as less fit individuals are less likely to survive and reproduce.

If Products Could Speak April 6
The document discusses biodiversity loss and threats to biodiversity such as habitat loss, pollution, climate change, and overexploitation of resources. It notes that the rate of biodiversity loss has accelerated in the past 50 years due to human actions that reduce diversity of plant and animal life. Efforts to conserve biodiversity include identifying threatened species, the threats they face, and goals for mitigating these threats. Examples of international agreements aimed at protecting biodiversity include the Convention on Biological Diversity. The document also discusses sustainable design frameworks like Cradle to Cradle that aim to create products and systems that cause no harm and integrate into natural biological and technical cycles.
The measurement of biodiversity
This document discusses various methods for measuring biodiversity, including species richness, evenness, disparity, and genetic variability. It notes that biodiversity cannot be reduced to a single number due to the complexities of various taxonomic concepts and differences in ecosystems. While higher productivity generally correlates with greater biodiversity, preserving biodiversity poses challenges for policymakers given difficulties in comparing biodiversity across environments.
D2 species and speciation
The document discusses speciation and the formation of new species. It defines key terms like allele frequency, gene pool, and reproductive isolation. It describes several mechanisms by which reproductive barriers can form between populations, including geographic, temporal, and behavioral isolation. Speciation occurs when genetic changes result in lineages that can no longer successfully interbreed. The document provides examples of allopatric speciation driven by geographic isolation, as well as pre- and post-zygotic barriers that reduce gene flow and lead to speciation.
Biodiversity: Living and Non-Living Resources
This document provides an overview of biodiversity in the Philippines. It begins by defining key terms like endemism. It then discusses the high plant diversity in the Philippines, noting there are an estimated 12,000 plant species, with many ferns, orchids, and mosses being endemic. The document highlights some examples of endemic species within these groups. It also addresses the country's status as one of 17 megadiverse countries and notes the large numbers of endemic animal species like birds, mammals, and reptiles found in the Philippines. Threats to the country's biodiversity like habitat loss are also examined.

Introduction
Biodiversity, short for biological diversity, includes the genetic variation between all organisms, species, and
populations, and all of their complex communities and ecosystems. It also reflects to the interrelatedness of
genes, species, and ecosystems and their interactions with the environment. Biodiversity is not evenly distrib-
uted across the globe; rather, it varies greatly and even varies within regions. It is partially ruled by climate,
whereas tropical regions can support more species than a polar climate. In whole, biodiversity represents
variation within three levels:
• Species diversity
• Ecosystem diversity

The document discusses factors that affect population growth such as an organism's reproduction rate and environmental resistances like disease. It notes that the current world population is over 7 billion and continues growing due to increased food availability and medical advances overcoming resistances. High reproduction rates combined with fewer limiting factors allow populations to approach the carrying capacity of their environment until reaching equilibrium.
Biodiversity Essays
Biodiversity refers to the variety of species in a given ecosystem. The human impact on biodiversity has led to a significant loss of species globally. Habitat destruction is a major cause of this loss, as human development eliminates natural habitats. This reduction in habitats puts pressure on species and can lead to extinction if they cannot adapt. Preserving biodiversity is important as every species plays a role in the health of ecosystems. Studies are ongoing to understand biodiversity and protect endangered species.

The document discusses using macroinvertebrate data collected through the GLOBE program to assess the health of Schooner Creek in Lincoln City, Oregon. The author analyzes macroinvertebrate data collected by students from Taft Elementary School, finding a diversity of sensitive species and abundance of moderately tolerant species, indicating the creek has good water quality.
Natural Selection
This presentation discusses Natural Selection. Of the world's most amazing ideas in science history.
Why is biodiversity so important
Our planet’s diverse, thriving ecosystems may seem like permanent fixtures, but they’re actually vulnerable to collapse. Jungles can become deserts, and reefs can become lifeless rocks. What makes one ecosystem strong and another weak in the face of change? Kim Preshoff details why the answer, to a large extent, is biodiversity.
CONSERVATION X LABS CONCEPT_VERSION 4.11_110514
The document discusses the concept of Conservation X Labs, which aims to address the global conservation crisis through technological and financial innovation. It seeks to dramatically increase the efficacy, speed, sustainability and scale of conservation efforts by harnessing advances in science, technology, connectivity, and behavioral change. Specifically, Conservation X Labs focuses on engineering biological resilience against environmental changes, changing conservation incentives and demand structures, and improving understanding of species threats and biology. The goal is to develop breakthrough solutions that can help end human-induced extinction.
BIODIVERSITY & ITS TYPES
This document provides an overview of biodiversity. It defines biodiversity as the variety of life on Earth, including genetic diversity within species, species diversity within biological communities, and ecosystem diversity within and across landscapes. It discusses how biodiversity has evolved over 3.5 billion years and increased rapidly during the Cambrian explosion. While species diversity in the oceans has increased logistically, diversity on land has grown exponentially. The document also outlines different types of biodiversity like taxonomic diversity, ecological diversity, and genetic diversity. It notes that most terrestrial diversity is found in tropical forests and that an estimated 8.7 million species exist on Earth. The document concludes by discussing threats to biodiversity like habitat destruction and climate change, as well as conservation

The document examines potential failures in different types of bridges:
1. Suspension bridges can fail due to tensile forces in members B and D.
2. Beam bridges can fail due to compressive forces in members B, D, and E and tensile forces in member A.
3. Cable stay bridges can fail due to compressive forces in members A and C and tensile forces in members B and D.
Additional forces like torsion, shear, and resonance can also cause bridge failures and must be addressed in design. Structural flaws and weather events combining dynamic forces can lead to collapse.

The document discusses applying weights to an object and labeling the resulting tension and compression forces. It also asks if any familiar shapes are observed from applying the weights.
Shapes ppt
This document encourages a child to multitask by eating a snack while making shapes, and gives them 10 minutes to finish making shapes and cleaning up using an online stopwatch timer.
Bridge lesson 5 8
Forces act on bridges in both tension and compression. Tension forces pull outward while compression forces push inward, and it is the balance of these opposing forces that allows bridges to stand stable and support weight. Ant societies demonstrate similar principles, as ants link together using hooked claws to form rafts and highways that distribute weight across many individuals, much like modern bridges distribute weight across their supporting structures.
Bridges 3 4
The document discusses the invisible forces acting on an ant walking on a table. It mentions gravity as the main force pulling the ant down, and tension and compression forces from the table surface pushing and pulling on the ant from different directions to keep it balanced while walking.

Zombie land rochester
A nuclear disaster at a power plant in Webster, NY has turned the local population into zombies. The zombies are organizing into communities and reproducing, with zombie babies being born. As a scientist, you have been studying the zombies to understand how their vital organs repair themselves and keep functioning despite being dead. Through experiments, you have discovered that the zombies' organs do require living cells to survive. You need to research cellular regeneration and find a way to eliminate the zombie threat, possibly through manipulating genetics to select for a "non-zombie cuteness" gene and repopulating the area with normal human babies.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
