From Death Comes Life: Recovery and Revolution in the Wake of Epidemic Outbreaks of Mountain Pine Beetle
|
Excerpt : “Part of the initial increase in nutrients and moisture under dead and dying trees is due to reduced uptake,” Rhoades says. “But the sick and d... |
Contemporary Evolution of Reproductive Isolation and Phenotypic Divergence in Sympatry along a Migratory Divide
|
Understanding the influence of human-induced changes on the evolutionary trajectories of populations is a fundamental problem [1, 2]. The evolution of reproduct... |
WATER, CLIMATE CHANGE, AND FORESTS Watershed Stewardship for a Changing Climate
|
Water from forested watersheds provides irreplaceable habitat for aquatic and riparian species and supports our homes, farms, industries, and energy production.... |
Temperature increase of 21st century mitigation scenarios
|
Estimates of 21st Century global-mean surface temperature in- crease have generally been based on scenarios that do not include climate policies. Newly develope... |
Increased soil emissions of potent greenhouse gases under increased atmospheric CO2
|
Increasing concentrations of atmospheric carbon dioxide (CO2) can affect biotic and abiotic conditions in soil, such as microbial activity and water content 1,2... |
Combined climate and carbon-cycle effects of large-scale deforestation
|
The prevention of deforestation and promotion of afforestation have often been cited as strategies to slow global warming. Deforestation releases CO2 to the atm... |
Satellite methods underestimate indirect climate forcing by aerosols
|
Satellite-based estimates of the aerosol indirect effect (AIE) are consistently smaller than the estimates from global aerosol models, and, partly as a result o... |
WWF : A CLOSING WINDOW OF OPPORTUNITY - GLOBAL GREENHOUSE REALITY 2008
|
Scientific evidence accumulating since the IPCC’s Fourth Assessment Report reveals that global warming is accelerating, at times far beyond projections outlin... |
Sagebrush carrying out hydraulic lift enhances surface soil nitrogen cycling and nitrogen uptake into inflorescences
|
Plant roots serve as conduits for water flow not only from soil to leaves but also from wetter to drier soil. This hydraulic redistribution through root systems... |
Gas production in the Barnett Shale obeys a simple scaling theory
|
Natural gas from tight shale formations will provide the United States with a major source of energy over the next several decades. Estimates of gas production ... |
Quantifying the Extent of North American Mammal Extinction Relative to the Pre-Anthropogenic Baseline
|
Earth has experienced five major extinction events in the past 450 million years. Many scientists suggest we are now witnessing a sixth, driven by human impacts... |
Measuring the effectiveness of protected area networks in reducing deforestation
|
Global efforts to reduce tropical deforestation rely heavily on the establishment of protected areas. Measuring the effectiveness of these areas is difficult be... |

Genome diversity in wild grasses under environmental stress
|
Patterns of diversity distribution in the Isa defense locus in wild- barley populations suggest adaptive selection at this locus. The extent to which environmen... |
Local climatic drivers of changes in phenology at a boreal-temperate ecotone in eastern North America
|
Ecosystems in biogeographical transition zones, or ecotones, tend to be highly sensitive to climate and can provide early indications of future change. To evalu... |
Ecosystem services: Foundations, opportunities, and challenges for the forest products sector
|
From the text: A social trap (7) is created when economic markets cannot efficiently or equitably deal with common pool resources (Hardin, 1968), which is often... |
Rising atmospheric carbon dioxide concentration and the future of C 4 crops for food and fuel
|
Crops with the C4 photosynthetic pathway are vital to global food supply, particularly in the tropical regions where human well-being and agricultural productiv... |
Correlations among species distributions, human density and human infrastructure across the high biodiversity tropical mountains of Africa
|
This paper explores whether spatial variation in the biodiversity values of vertebrates and plants (species richness, range-size rarity and number or proportion... |
The Role of Livestock Production in Carbon and Nitrogen Cycles
|
This review looks at the role of the livestock sector in carbon (C) and nitrogen (N) cycles from a global perspective and considers impacts at the various stage... |
