National Climate Change and Wildlife Science Center – September 9, 2014
The National Climate Change and Wildlife Science Center will hold a webinar on Extreme Climate Events and Species Population Dynamics: Overriding Influence or Not Such a Big Deal? This webinar will be held on September 9, 2014 at 3:00 p.m. EDT. Extreme events (floods, droughts, and fires) have a high public profile and changes in their frequency, magnitude, and duration have been linked to changes in climate. For species populations, these events are often associated with high levels of mortality and major changes in habitat, suggesting a strong influence on population dynamics. At the same time, the life history and reproductive strategy of many species, particularly those associated with highly seasonal and variable climates, may mitigate the long-term effects of extreme events relative to more gradual changes in climate. Given the difficulty of accurately forecasting climate extremes understanding their role in population dynamics is critical for effective management and climate adaptation. In this talk, we review some of the basic determinants of population response to extreme events, using case studies based on long-term data from natural populations in the northeastern region, and present a modeling framework for evaluating the relative impacts of changes in timing, duration, and magnitude. We also consider the potential for human responses to perceived and actual risks from climate extremes to interact with, and in some cases override the direct effects of the events themselves.

National Climate Change and Wildlife Science Center – October 14, 2014
The National Climate Change and Wildlife Science Center will hold a webinar onPredicting Climate Change Impacts on River Ecosystems and Salmonids across the Pacific Northwest to be held on October 14, 2014 at 2:00 p.m. EDT. Trout and salmon populations, which play a critical role in many ecosystems and economies, have dramatically declined in the Pacific Northwest (PNW) due to habitat degradation and fragmentation and introductions of invasive species, and are expected to be further impacted by future climate change. Understanding how climate change will influence the abundance, distribution, genetic diversity, and value of these native fish species is crucial for their management and recovery. This project will use modeling techniques to study how climate change might affect freshwater habitats of key trout and salmon species throughout the PNW. The goal of the study is to develop and provide novel tools that will help managers predict and respond to potential climate change induced impacts on habitats, populations, and economies.
