University of Illinois College of Agricultural, Consumer and Environmental Sciences Due to the introduction of exotic pests and pathogens, tree species are being eliminated one by one from forest ecosystems. In some cases, scientists can observe immediately how their loss affects the environment, whereas in other cases, creative puzzle solving and analysis reveal unexpected repercussions. In the case of the loss of the hemlock tree, University of Illinois landscape and ecosystem ecologist...

A new study by biologists at Mercyhurst University focuses on the influence of climate change, particularly warmer winters, on the survival and potential fecundity of cold-blooded animals. Cold blooded animals, or ectotherms, do not have an internal mechanism for regulating body temperature. Instead, they rely on solar energy captured by the environment. The purpose of the Mercyhurst study, a collaboration of Michael Elnitsky, Ph.D., assistant professor of biology; and students Drew...

A recent analysis of two decades of USDA Forest Service Forest Inventory and Analysis (FIA) data shows the live volume of hemlocks in the eastern United States still increasing despite spreading infestations of hemlock woolly adelgid. FIA scientists from the Forest Service Southern Research Station (SRS) and Northern Research Station (NRS) published the information as an SRS e-Science Update in early August. The FIA researchers conducted the analysis for this update on 20 years of data...
