This document discusses light and temperature effects on plants grown in high tunnels. It covers several topics: light intensity and photosynthesis; carbon dioxide levels; light color; shading issues; and temperature effects on plant development, stem elongation, photosynthesis, and flowering. For each topic, it provides data on different plant species' responses and optimal conditions. The overall focus is on understanding the light and temperature requirements of various crops to maximize growth and yield in high tunnel environments.
The document discusses factors that affect the light intensity in greenhouses and how they impact photosynthesis. It notes that there is an optimal light intensity for photosynthesis that varies by species and growth stage. Both too much and too little light can lower the net photosynthesis rate. The document also outlines ways to maximize and reduce light intensity in greenhouses, such as greenhouse design, plant spacing, using shade cloth or paint, and geographic orientation.
This document summarizes research on characterizing aerosols in a tropical premontane cloud forest. Aerosol and particle counts were higher on "event days" with strong winds from the forest, compared to "typical days" with urban-influenced winds. Raman spectroscopy and pollen analysis found forest-sourced organics and increased pollen on event days, while typical days had more urban pollutants like sulfates and nitrates. The findings suggest forest-generated aerosols are important for cloud formation, and land use changes reducing these could decrease cloud cover and alter the ecosystem. Future work is needed to better link aerosol properties to cloud formation and conduct long-term monitoring of multiple forest sites.

Global carbon dioxide levels reached 400 parts per million for the first time in 800,000 years due to greenhouse gas emissions from human activities like burning fossil fuels. This increased CO2 in the atmosphere is causing global warming and climate change through the greenhouse effect. Effects of climate change include rising sea levels, more extreme weather, and threats to plants and animals. The document calls for actions like using renewable energy instead of fossil fuels, reducing consumption, and growing more trees to help address this global problem.
1. Ground-level ozone is produced by chemical reactions between volatile organic compounds and nitrogen oxides in the presence of sunlight. It can adversely affect crop yields, tree health and growth.
2. The Slovenian Forestry Institute has monitored ozone levels and visible injury on forest trees for over 10 years. Studies in 2013 and 2014 found no visible ozone symptoms in urban forests in Ljubljana, though symptoms have been observed in other years.
3. Global models predict that ground-level ozone concentrations will increase in the future without measures to reduce precursor emissions. Urban areas can help by planting native, ozone-resistant tree species and increasing education about trees and air pollution.
This document discusses a sound wave fire extinguisher invented by two engineering students. It works by using focused sound waves between 30-60 Hz to separate burning fuel from oxygen, extinguishing small fires. The extinguisher consists of an amplifier and cardboard collimator to focus sound waves. It can quickly extinguish small alcohol-fueled fires and only cost $600 to build. The document outlines the working principles and potential uses of this chemical-free, water-free fire extinguishing technology, including potential commercial applications and uses in situations where traditional extinguishers are impractical. It also discusses the technology's promise for use in Bangladesh, as a cheaper, simpler alternative to other extinguishers.
1. The document outlines the procedures for a lab experiment on photosynthesis, including measuring the effects of light intensity and wavelength on photosynthetic rate.
2. Students will take readings from cuvettes containing chloroplasts, water and a dye to act as the electron acceptor over time when exposed to different light conditions.
3. The results will be presented in four figures - two graphs of absorbance over time, and two graphs of reaction rate against the experimental parameters tested - with detailed captions explaining each graph.
This experiment tested how limiting different light wavelengths affects the rate of photosynthesis in leaves. Leaves were placed in solutions with different food coloring to limit red, green, blue, or violet light. The time for leaves to float, indicating photosynthesis, was recorded. On average, leaves in the red solution took the longest at 5:54 minutes, supporting that plants use red light most for photosynthesis. However, leaves in the green solution did not float fastest as expected, limiting the conclusions that can be drawn about how each wavelength affects photosynthesis.
The document describes a lab experiment that tested how the rate of photosynthesis is affected by leaf color. Students used leaf disks of light green, dark green, and yellow leaves submerged in a sodium bicarbonate solution. They measured the time it took for each disk to rise to the surface as photosynthesis replaced air space with oxygen. Results showed yellow leaf disks rose fastest, suggesting color affects light absorption and therefore photosynthesis rate.

1. The document discusses growing native trees that can thrive for 300 years by planting locally native species and accounting for substantial environmental changes expected from climate change and new pests/pathogens.
2. Resilience measures are needed to cover several centuries since current approaches can't be tested or targeted under high uncertainty about impacts.
3. Greater tree diversity is suggested, including non-local genotypes, replacement species, and pre-emptive diversification with analogue species to improve resilience of forests over centuries.
This document discusses various environmental issues related to pollution and climate change, including the greenhouse effect, acid rain, ozone layer depletion, urban heat islands, and light pollution. It provides details on the causes and effects of each issue and potential methods for control and mitigation. The greenhouse effect is caused by greenhouse gases like CO2 trapping heat in the lower atmosphere. Acid rain forms from SO2 and NOx emissions and damages forests and aquatic ecosystems. Ozone layer depletion is mainly due to CFC emissions allowing more UV rays to reach the surface. Urban heat islands occur where cities are warmer than surrounding rural areas due to factors like lack of vegetation and heat-absorbing surfaces. Light pollution disrupts ecosystems, observatories
Basics of High Tunnel Production. Presentation by Terry Nennich, University of Minnesota Extension Professor. From the 2009 Minnesota Statewide High Tunnel Conference held in Alexandria, MN on Dec. 2-3, 2009.
This document discusses climate change, global warming, and ozone layer depletion. It defines climate and climate change, noting that climate change is altering weather patterns and threatening sustainability. It explains that greenhouse gases like carbon dioxide are trapping more heat in the atmosphere and warming the Earth. The document also describes how CFCs and other chemicals released into the atmosphere are depleting the ozone layer, which protects life from UV radiation, and discusses evidence of climate change like melting glaciers and rising sea levels. Solutions proposed include transitioning to renewable energy and reducing greenhouse gas emissions.
This document provides information on topics related to ecology and evolution. It begins by defining key terms in ecology such as ecology, ecosystem, population, community, species, and habitat. It then describes autotrophs and heterotrophs, including consumers, detritivores, and saprotrophs. Food chains and food webs are explained. The document also covers trophic levels, energy flow through ecosystems, and shapes of pyramids of energy. Other topics include nutrient cycling, the enhanced greenhouse effect, population growth curves, limiting factors to population growth, and evidence for evolution such as the fossil record, selective breeding, and homologous structures.
This document discusses ecology and the enhanced greenhouse effect. It defines key ecological terms like ecosystem, population, community, species, habitat, autotrophs, heterotrophs, trophic levels, and food webs. It explains how light energy enters ecosystems and is transferred between trophic levels, and how nutrients must be recycled. It then discusses the greenhouse effect, how human activities like fossil fuel use and deforestation enhance this effect, and the potential consequences of climate change like sea level rise and species displacement. Finally, it outlines some actions that can be taken to reduce carbon emissions and artificially sequester carbon.
The document provides an overview of what is known about carbon storage and sequestration in various UK terrestrial habitats. It notes that the evidence base is still developing and varies in certainty between habitat types. Key points made include:
- Woodlands and peatlands store the most carbon, primarily in soils. New woodland creation and restoration of degraded habitats can sequester carbon.
- Grasslands are also significant carbon stores, though intensive management may reduce soil carbon. Reducing grazing and soil disturbance helps sequestration.
- Heathlands store carbon in soils, especially wet heathlands. Management practices should minimize soil disturbance to avoid carbon emissions.
- Further research is still needed to better quantify carbon metrics

The document discusses concepts related to sustainable development and bioclimatic design. It defines key terms like sustainability, bioclimatic architecture, and bioclimatic design. The principles of bioclimatic design aim to use natural heating/cooling according to the local climate. Examples discussed include traditional Spanish hacienda designs and Scandinavian sod houses that integrated local materials and vegetation for insulation and temperature regulation. Causes of environmental issues like pollution, degradation, and their impacts are also examined.
The document discusses the greenhouse effect and global warming. It explains that greenhouse gases like carbon dioxide and methane trap heat in the atmosphere and cause the planet to warm up. It notes the key sources of these gases like the burning of fossil fuels and deforestation. The summary describes how a warming planet could lead to problems like more extreme weather, rising sea levels, and disrupted ecosystems that impact human health, plants and animals. It outlines some international efforts like the Kyoto Protocol and Paris Agreement to reduce greenhouse gas emissions and mitigate climate change.

Social, Economical and Environmental impacts of conventional and non conventional energy sources, health hazard, bio diversity loss, Emission hazard, Ozone layer depletion, smog, Battery hazard, nuclear hazard
This talk was given in a CEH section meeting in June 2012 to a group of 40+ colleagues and peers with many different disciplinary backgrounds at CEH Lancaster. The presentation shows some of the early findings from an experiment set up excluding roots and/or plant litter from soil under a Miscanthus plantation in the UK.
The document discusses biodiversity loss and endangered species due to habitat destruction and fragmentation. It notes that habitat loss and invasive species are major threats, putting native species at risk of extinction. This can destabilize ecosystems and negatively impact both wildlife and humans by reducing food supplies and potential medical treatments. The document encourages actions like keeping pets indoors, choosing tap water over bottled, adjusting the thermostat, and volunteering or donating to conservation efforts to help address these issues.
Trees play a vital role in combating climate change by absorbing carbon dioxide from the atmosphere. Nigeria once had extensive forests but has experienced severe deforestation, with the annual loss of 350,000-400,000 hectares of forest between 2000-2005. This deforestation is primarily due to logging, agriculture, and fuelwood collection, which over 70% of Nigerian households still rely on for cooking. The massive deforestation has led to environmental and economic problems for Nigeria, including desertification, heat waves, drought, loss of biodiversity, and carbon emissions. The document proposes strategies to address this, including expanding tree planting programs, protecting existing forests, pursuing more sustainable industrial development, and developing innovative solutions to energy
Biology presentation chapter 9.2 (1) by kosalini narendirankokokutti
The document discusses two main topics:
1) The greenhouse effect, which is caused by greenhouse gases like carbon dioxide trapping heat in the atmosphere similarly to how glass traps heat in a greenhouse. Concentrations of these gases have increased since the industrial revolution due to human activity.
2) The thinning of the ozone layer, which filters out UV radiation. The ozone layer has been decreasing since the 1970s due to CFCs, exposing organisms to more UV radiation and increasing health risks like skin cancer.
