Caddisfly behavioral responses to drying cues in temporary ponds: Implications for effects of climate change.
(The University of Chicago Press, 2016-02-11)Aquatic organisms that live at high latitudes and elevations are especially vulnerable to climate-change-induced alterations in snowpack, snowmelt, and evaporation rates, all of which affect basin filling and drying dates. ... -
Fluctuation in a Rocky Mountain population of salamanders: Anthropogenic acidification of natural variation?
(Society for the Study of Amphibians and Reptiles, 1992)We monitored the demographics of the salamander Ambystoma tigrinum nebulosum as part of a community-wide study on the effects of acidification in sub-alpine (elevation 3600 m) ponds in central Colorado. A decline in A. ... -
Intraguild predation and competition between larval dragonflies: direct and indirect effects on shared prey
(Ecological Society of America, 1993-01-01)We conducted manipulative field experiments in artificial ponds to quantify the predatory impact of larvae of a migratory dragonfly (Tramea lacerata) on a common resident dragonfly species (Erythemis simplicicollis), and ... -
Nonlinear effects of consumer density on multiple ecosystem processes
(British Ecological Society, 2012)1. In the face of human-induced declines in the abundance of common species, ecologists have become interested in quantifying how changes in density affect rates of biophysical processes, hence ecosystem function. We ...
