PDF Hydrology, phenology and the USA National Phenology Network [More info]
Explains how hydrologic factors interact with phenology
Influence of Riparian Tree Phenology on Lower Colorado River Spring-Migrating Birds: Implications of Flower Cueing [More info]
North American bird phenology program [More info]
PDF Remote sensing of land surface phenology [More info]
Shows how we can use remote sensing to study natural phenomena that vary seasonally but whose timing is affected by both shorter- and longer-term variations in climate or other, similar environmental conditions.
Remote sensing phenology [More info]
PDF The USA National Phenology Network; taking the pulse of our planet [More info]
Explains what phenology is, how it can help people, and how people can get involved in developing this type of data.
PDF A Neotropical Migrant Bird's Dilemma - Where to Stop for a Good Meal [More info]
Studying 28 species of warblers, flycatchers, tanagers, and vireos, we find the birds relied on the flowering of honey mesquite to detect the availability of insects they eat.
Changing Arctic Ecosystems-Measuring and forecasting the response of Alaska's terrestrial ecosystem to a warming climate [More info]
Combining genetic data with current and predicted climate scenarios, we are modeling the predicted future distributions of wildlife populations in the Arctic and identifying key environmental variables that determine important animal habitat.
Climate Change and Wildlife Health: Direct and Indirect Effects [More info]
Addresses geographic range and distribution of wildlife diseases, plant and animal phenology, wildlife host-pathogen interactions, and disease patterns in wildlife.
Climatic changes and effect on wild sheep habitat [More info]
Preliminary results indicate significant changes in Dall sheep diet accompanying vegetation changes and upslope retreat of glaciers.
PDF Detecting Evidence of Climate Change in the Forests of the Eastern United States [More info]
The relation between seasonal forest change and weather is being tracked and analyzed by comparing precise field observations to regional patterns shown in long-term satellite imagery.
PDF Using observed warming to identify hazards to Mozambique maize production [More info]
Over 30 years of substantial warming, the timing of life cycle events in maize here has changed, threatening the crop yield by exposing the plant at sensitive phases in its life cycle to increased heat and drought, and lowering the weight of its grains.
