A female three-toed box turtle has a small radio tag on its upper shell. The turtle is standing on a forest floor made of dried leaves.

St. Louis scientists including LEC postdoctoral fellow, Stella Uiterwaal, collaborate on new study of wildlife in one of America’s greatest urban parks called the Forest Park Living Lab. The Forest Park Living Lab received a LEC seed grant in 2022.

Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects (Links to an external site)

Deer, caribou, bison and other similar animals are often infected by a range of internal parasites, including worms called helminths. Although many of these infections are not lethal, they can still impact health or animal behavior. A new study led by Washington University in St. Louis senior scientist, Amanda Koltz, uses a mathematical model and a global meta-analysis to highlight the cascading consequences of common parasitic infections in wild animals on terrestrial ecosystems. This work was funded by a LEC Seed grant.

With funding support from LEC, researchers look at whether Ozark oases at Tyson Research Center — climate change refugia — could help species persist in spite of rising temperatures.

Andean forests have high potential to store carbon under climate change. The study — which draws upon two decades of data from 119 forest-monitoring plots in Colombia, Ecuador, Peru, Bolivia and Argentina — was produced by an international team of scientists including researchers supported by the Living Earth Collaborative at Washington University in St. Louis. The lead author was Alvaro Duque from the Universidad Nacional de Colombia Sede Medellín.

Climate change is affecting the spread and severity of infectious diseases around the world. The research, led by Vanessa Ezenwa, a professor of ecology at the University of Georgia, and funded by the Living Earth Collaborative at Washington University in St. Louis, describes how parasites can cause animals to produce more methane, a powerful greenhouse gas.
