The City of Pittsburgh, formerly the capital of the American steel industry, suffered economic and social collapse in the late 1980s and 1990s. Since then, it has experienced an economic renaissance supported by the tech and medical care industries. However, despite the surprising recovery of the city, collapsed tax bases...

Variable ocean conditions can greatly impact
prey assemblages and predator foraging in marine ecosystems.
Our goal was to better understand how a change in
ocean conditions influenced dietary niche overlap among
a suite of midtrophic-level predators. We examined the
diets of three fishes and one seabird off central Oregon
during...

Natural resources play a crucial role in human society by providing both market value and non-market value. Effective management of these resources is necessary to achieve a balance between economic value and other non-market benefits. Econometric studies focusing on natural resource management help us understand the costs and benefits of...
Rapid adaptation and evolution based on standing genetic variation and novel mutations is likely to be one of the primary ways that species survive the widespread anthropogenic environmental changes expected of the next century. Three-spined stickleback (Gasterosteus aculeatus) are known to be capable of extremely quick, dramatic adaptation in response...
Assessing AI systems is difficult. Humans rely on AI systems in increasing ways, both visible and invisible, meaning a variety of stakeholders need a variety of assessment tools (e.g., a professional auditor, a developer, and an end user all have different needs). We posit that it is possible to provide...
Although there are considerable site-based data for individual or groups of ecosystems, these datasets are widely scattered, have different data formats and conventions, and often have limited accessibility. At the broader scale, national datasets exist for a large number of geospatial features of land, water, and air that are needed...

Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they
fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling
at a scale functional for management. We used stratified random sampling and generalized linear mixed
models to test hypotheses...
