Studies of avian movement ecology afford essential insights regarding species' life histories, population dynamics, habitat and resource requirements, and other ecological relationships. While it is widely recognized that events in different stages of the annual cycle have important implications for processes in avian ecology, evolution, and conservation, challenges associated with...
Snags, standing dead trees, are used by many species of wildlife. Despite the importance of snags their basic ecology remains unknown.
Some forest management practices eliminate snags from the forest with a concomitant effect upon snag-dependent wildlife. My objective was to describe the density, spatial distribution, and physical character of...
Law enforcement in Indian Country has been characterized as a “maze of injustice”—one in which offenders too easily escape and victims are too easily lost (Amnesty International, 2007). Tribal, state, and federal governments have recently sought to amend this through the passage of the Tribal Law and Order Act (TLOA)...
Projected intensification of drought as a result of climate change may reduce the capacity of streams to rear fish, exacerbating the challenge of recovering ESA-listed salmon populations. Without management intervention, some stocks will likely go extinct as stream drying and fragmentation reduce juvenile survival to unsustainable levels. To offset drought-related...
Non-coding ribonucleic acid (ncRNA) is of interest for its diverse roles in cell and viral biology. RNA molecules vary greatly in terms of size, structure, and function. In recent years, the modification of existing RNA structures has been used for biochemical methods of enormous impact including CRISPR and RNAi methods....
Water quality impacts both human and ecosystem health. Many pharmaceuticals and personal care products are considered contaminants of emerging concern (CEC) due to their bioactive properties. Among these, metformin—the most commonly prescribed drug for treatment of type 2 diabetes—has been reported at high concentrations (μg L⁻¹) in stream, lake, and...
Atmospheric carbon reduction is arguably the most crucial facet among efforts to mitigate climate change. The Fifth International Panel of Climate Change report emphasizes a worldwide goal of maintaining global temperature elevation less than 1.5°C above pre-industrial temperatures. This report also acknowledges without the proper utilization of counteractive emission strategies...
Arctic cod (Boreogadus saida) is an ecologically significant species that plays a critical role channeling energy throughout the Arctic marine food web. Arctic cod is uniquely adapted to occupy ice edge habitats, however, a basic understanding of its larval physiology and habitat requirements is lacking due to widespread sea ice...
The role that anthropogenic and natural habitats in estuaries play in long-term population trends for Oregon’s nearshore marine fishes is poorly understood, in part due to limited temporal sampling. One important nearshore marine group is northeastern Pacific rockfishes (Sebastes spp.), which are highly diverse, with around 96 documented species, and...
