Climate change, predators, and the trickle down effects on ecosystems

Ecologists are just beginning to understand how the impacts of climate change are affecting predatory keystone species and their ecosystems. Ecologists will report on this and other climate-ecosystem research news at the Ecological Society of America’s 2014 Annual Meeting in Sacramento, Cal., August 10–15.

Annual Meeting

Mark your Calendar!

This year’s meeting will emphasize the society’s mission of supporting ecologists throughout their careers. The emphasis recognizes the need for us to continually invest in all the people who advance the science and practice of ecology. Among many aspects of professional development, we are planning programming and invite contributions that consider the transformational potential of effective mentorship.

To determine the extent to which a large restoration effort in the 1990s altered the abundance and stability of the Butte Creek population of spring-run Chinook Salmon and of the entire spring-run stock complex in California's Central Valley, Cordoleani et al. compared annual trends before and after restoration and correlated adult abundance to floodplain inundation area. This research, published in the March issue of Ecosphere, underscores the importance of restoring a connected mosaic of aquatic habitats across modified landscapes, including cold-water refugia and floodplains, to preserve multiple (across-population) life history pathways for increasing salmon stock complex stability and abundance.
