Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates,...

Stable oxygen and carbon isotope δ[superscript 18]O and δ[superscript 13]C analyses of otoliths are becoming increasingly common in fisheries science and management. However, little is known about the statistical properties of isotopic data and...

Anadromous salmonids are viewed as a prized commodity and cultural symbol throughout the Pacific coast of North America. Unfortunately, several native salmonid populations are threatened or at risk of extinction. Despite this, little is known...

Western Atlantic synodontid species were studied as part of an ongoing effort to reanalyze Caribbean shorefish diversity. A neighbor-joining tree constructed from cytochrome c oxidase I (COI) data revealed 2 highly divergent genetic lineages...

Although climate acts as a fundamental constraint on the distribution of
organisms, understanding how this relationship between climate and distribution varies over a
species’ range is critical for addressing the potential impacts of accelerated...

Background: Scientists rarely reuse expert knowledge of phylogeny, in spite of years of effort to assemble a great
“Tree of Life” (ToL). A notable exception involves the use of Phylomatic, which provides tools to generate custom
phylogenies from a...

Rotary screw traps are used throughout the West Coast of North America to capture emigrating juvenile salmonids. Calibrating the capture efficiency of each trap is essential for valid estimates of fish passage. We released Passive Integrated...

The Pacific salmonid species Oncorhynchus mykiss is separated into a migratory form (steelhead trout) and a
non-migratory form (rainbow trout). A decrease in water temperature is likely a cue triggering downstream
behavior in the migratory form,...

We investigated the movements and selection of settlement sites of translocated pygmy rabbits
(Brachylagus idahoensis) in southeastern Oregon from June to December 2008. We captured, radio tagged,
and translocated 59 pygmy rabbits across big...

Four streams-Clear Fork, Lost Creek, Camp Creek and Still Creek-in northwestern Oregon's Sandy River Basin were monitored for temperature, dissolved oxygen levels, and fecal bacterial concentrations in a multi-year analysis examining stream health...

Identifying drivers of contact rates among individuals is critical to understanding
disease dynamics and implementing targeted control measures. We studied the interaction
patterns of 149 female elk (Cervus canadensis) distributed across five...

Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for
reconstructing the environmental history of many marine species. However, the extent to which ambient
environmental conditions...

Light availability strongly influences stream primary production, water temperatures
and resource availability at the base of stream food webs. In headwater streams, light
is regulated primarily by the riparian forest, but few studies have...
