Persistence of a declining anuran species across its distribution Persistence of a declining anuran species across its distribution
Information on a species’ population dynamics, such as changes in abundance and distribution, can be used to identify declining populations and initiate conservation efforts and protections. For the Ornate Chorus Frog (Pseudacris ornata), anecdotal observations of local extirpation and population declines have been noted, but trends in its range-wide population status are generally...
Decision support tools for brown pelican management in the northern Gulf of America (Gulf of Mexico) Decision support tools for brown pelican management in the northern Gulf of America (Gulf of Mexico)
Management plans with clear priorities can help to achieve brown pelican Pelecanus occidentalis conservation objectives in the northern Gulf of America (Gulf of Mexico). Efforts to establish clear priorities can be hindered by information gaps, especially those related to the uncertainty associated with changing conditions that influence brown pelican populations. We addressed these gaps...
Factors structuring macrofaunal communities of hydrocarbon seeps along the Cascadia margin Factors structuring macrofaunal communities of hydrocarbon seeps along the Cascadia margin
Cold seeps, fueled by hydrocarbon-based chemosynthesis, support unique benthic communities that can vary across small spatial scales influenced by local geochemistry. We examined the community structure and function of macrofauna in cold seeps along the Cascadia margin on the edge of gas hydrate stability—a dynamic environment that may fluctuate as seafloor temperatures change. These...
