Mitigating The Effects Of Climate Change With Wind Energy And Gis, Rachael Isphording, Richard Snow, Mary Snow Dec 2014

Mitigating The Effects Of Climate Change With Wind Energy And Gis, Rachael Isphording, Richard Snow, Mary Snow

Publications

The climate is changing, and humans are heavily exacerbating these changes. As the effects of climate change are being felt across the planet, scientists and policy makers are uniting to increase mitigation efforts and are researching renewable, clean energy sources to reduce the amount of greenhouse gas emissions released into the atmosphere during energy production. Of the different renewable energy technologies, wind energy is one of the most researched and implemented. Over the past twenty years, researchers have been applying Geographic Information Systems (GIS) to their climate change studies. GIS allows the user to spatially view, manipulate, and analyze data …


Pushing The Pace Of Tree Species Migration, Eli D. Lazarus, Brian Mcgill Aug 2014

Pushing The Pace Of Tree Species Migration, Eli D. Lazarus, Brian Mcgill

Publications

Plants and animals have responded to past climate changes by migrating with habitable environments, sometimes shifting the boundaries of their geographic ranges by tens of kilometers per year or more. Species migrating in response to present climate conditions, however, must contend with landscapes fragmented by anthropogenic disturbance. We consider this problem in the context of wind-dispersed tree species. Mechanisms of long-distance seed dispersal make these species capable of rapid migration rates. Models of species-front migration suggest that even tree species with the capacity for long-distance dispersal will be unable to keep pace with future spatial changes in temperature gradients, exclusive …


Applications Of Satellite Remote Sensing In The Environment, Rajee Olaganathan, Muhammad Ihsan Bin Ibrahim, Huang Meitong, Tan Yong Jie Shawn, Wilson Tok Wei Sheng, Et Al. May 2014

Applications Of Satellite Remote Sensing In The Environment, Rajee Olaganathan, Muhammad Ihsan Bin Ibrahim, Huang Meitong, Tan Yong Jie Shawn, Wilson Tok Wei Sheng, Et Al.

Publications

Since its inception, satellite remote sensing has enabled observations of environmental changes at inaccessible locations in meteorology, disaster control, oceanography, agriculture, glaciology, geology etc. Using the information gathered from satellite remote sensing, changes in the physical environment can be measured and the information are utilized to predict future patterns and achieve better environmental outcomes in different areas. This paper serves to highlight some of the areas in which satellite remote sensing has been applied. In meteorology, Earth’s solar radiation intensity, geothermal energy and wind velocity are measured by satellite remote sensing. Satellite imageries are also used for forecasting natural disasters …


The Complementary Niches Of Anthropocentric And Biocentric Conservationists, Malcolm L. Hunter Jr., Kent H. Redford, David Lindenmayer Apr 2014

The Complementary Niches Of Anthropocentric And Biocentric Conservationists, Malcolm L. Hunter Jr., Kent H. Redford, David Lindenmayer

Publications

A divergence of values has become apparent in recent debates between conservationists who focus on ecosystem services that can improve human well-being and those who focus on avoiding the extinction of species. These divergent points of view fall along a continuum from anthropocentric to biocentric values, but most conservationists are relatively closer to each other than to the ends of the spectrum. We have some concerns with both positions but emphasize that conservation for both people and all other species will be most effective if conservationists focus on articulating the values they all share, being respectful of divergent values, and …


An Assessment Of Methods And Remote-Sensing Derived Covariates For Regional Predictions Of 1 Km Daily Maximum Air Temperature, Beniot Parmentier, Brian Mcgill, Adam Wilson, James Regetz, Walter Jetz, Robert Guralnick, Mao-Ning Tuanmu, Natalie Robinson, Mark Schildhauer Jan 2014

An Assessment Of Methods And Remote-Sensing Derived Covariates For Regional Predictions Of 1 Km Daily Maximum Air Temperature, Beniot Parmentier, Brian Mcgill, Adam Wilson, James Regetz, Walter Jetz, Robert Guralnick, Mao-Ning Tuanmu, Natalie Robinson, Mark Schildhauer

Publications

The monitoring and prediction of biodiversity and environmental changes is constrained by the availability of accurate and spatially contiguous climatic variables at fine temporal and spatial grains. In this study, we evaluate best practices for generating gridded, one-kilometer resolution, daily maximum air temperature surfaces in a regional context, the state of Oregon, USA. Covariates used in the interpolation include remote sensing derived elevation, aspect, canopy height, percent forest cover and MODIS Land Surface Temperature (LST). Because of missing values, we aggregated daily LST values as long term (2000–2010) monthly climatologies to leverage its spatial detail in the interpolation. We predicted …
