- ... Heartwood samples from Juniperus virginiana, were extracted with liquid carbon dioxide and the bioactivity of carbon dioxide-derived cedarwood oil (CWO) towards several species of arthropods was investigated. Repellency or toxicity was tested for ants, ticks, and cockroaches. Ants in an outdoor bioassay were significantly repelled by the presence of cedarwood oil on a pole leading to a sugar-water ...

- ... Livestock grazing has context-dependent impacts on grassland plant and animal communities. In grassland ecosystems that have evolved with large herbivores, such as the North American Great Plains with bison (Bison bison), responses of plants to grazing are better understood, and more predictable, than responses of consumers. In 2003, we began a large-scale, replicated experiment to examine effects ...
