Fire, flooding, and felids: Deer and puma spatial ecology and predator-prey interactions in dynamic, subtropical wildlands
Cyclic and extreme ecological disturbances have the capacity to alter resources and thereby animal populations. Interactions between disturbance and resource availability can influence predator-prey interactions. Predator-prey responses to ecological disturbance may be more pronounced in herbivores …

Microbiome-centered Approaches to Marine Disturbance Ecology
… change continues to alter our global ecosystem, ecological disturbances will increase in both frequency and intensity. These ecological disturbances have been shown to significantly impact microbial communities, often altering composition and/or function. However, while disturbance events are …

Regeneration of Ccuyahoga Flats – [De]-Industrialized Riverfront in Cleveland, Ohio
… of [de]industrialization, including massive ecological disturbances. The Lower Cuyahoga River in Cleveland started facing those consequences when it was modified in the 1800s. The river channel was radically re-engineered with an aim to ease the movement of ships upstream and economize the …

Impacts of mountain pine beetle outbreak on biogeochemical cycling in a high elevation whitebark pine ecosystem
Ecological disturbances can significantly impact biogeochemical cycles in terrestrial ecosystems, but the effects of the current widespread mountain pine beetle outbreak on ecosystem processes like carbon (C) and nitrogen (N) cycling are poorly understood. This is especially true in high elevation …

Bees, Bombs, and Burns: Disturbance and the Native Bee Communities of Military and Other Public Lands in Virginia
Physical and ecological disturbances caused by military land use can create and maintain early successional habitats, which can support diverse communities of native plants and animals. These lands may serve as refugia, protecting rare, threatened, and endangered species that may have disappeared …

Modeling canopy foliar traits and disturbance interactions in central Texas woodlands.
The present study examines canopy foliar traits and their interactions with the greater ecosystem at multiple scales. Leaf mass/area ratios, nitrogen, and phosphorus were measured and were shown to correlate with relative light levels in some species. Leaf nutrition is used as the basis for a leaf …
