Inter-individual variation within social groups: how metabolic rate shapes the pace of life
… Furthermore, the metabolic theory of ecology posits that performance at any level of biological organization is a function of the MR of its constituent units. It has therefore been suggested that MR drives the widely observed covariance among these different levels of phenotypic …

EFFECTS OF FLOW REGIME ON FISHES AND FISHERIES: FROM LIFE HISTORIES TO ECOSYSTEM SERVICES
… and traits from individual organisms to ecosystems. Due to this strong linkage, anthropogenic modification of flow regimes in freshwater ecosystems worldwide continues to have major impacts on populations, species, communities, and ecosystems and the many services they provide to humans. …

Unraveling an uncertain future for the Great Basin: how climate, grass invasion, and wildfire interact to drive ecosystem function
… how these drivers interact to influence ecosystem function, and how such interactions may change in the future, can provide critical insight for building ecological resilience. This dissertation explores how changing moisture regimes interact with grass invasion and wildfire to modify …

Fire regime change and the boreal forest carbon cycle from 10,000 years ago to 2100 AD
… Alaska, incorporating the paleorecord into ecosystem model experiments, and applying insights from these approaches to the development of a statistical model for predicting fire regime change. Results reveal that recent burning is unprecedented in the last 10,000 years. Fire frequency …

The drivers of freshwater reservoir biogeochemical cycling and greenhouse gas emissions in a changing world
… oxygen (DO) concentrations in freshwater ecosystems, yet more frequent, powerful storms are occurring that temporarily increase DO availability. The net effect of these opposing forces results in anoxia (DO < 0.5 mg L-1) punctuated by short-term increases in DO. The availability of DO …

Parasites in freshwater mussels: community ecology and conservation
… populations, communities and the wider ecosystem (a host-centric view). The former contributes to understandings of what drives parasite community structure across scales, while the latter furthers knowledge on how the conservation of host species or the functioning of ecosystems may be …

Effects of land management and climate change on soil microbial communities in Appalachian forest ecosystems
In terrestrial ecosystems, microorganisms are the dominant drivers of virtually all ecosystem processes, particularly cycling of carbon (C), nitrogen (N), and phosphorus (P). These microbial functions are critical for promoting ecosystem services that support human well-being, such as provisioning …
