Patterns In Winter Stonefly Distribution Along A River Continuum And Land-Use Gradient In Northwest Arkansas Streams, Zachary Tipton

Graduate Theses and Dissertations

Freshwater ecosystems are facing a crisis with extinction rates of aquatic species exceeding those of their terrestrial counterparts by up to fivefold. This decline is predominantly attributed to evolving land use patterns within watersheds, leading to chemical and physical transformations in freshwater habitats. Northwest Arkansas (NWA) represents one of the fastest-growing regions in the United States, undergoing substantial shifts in land use. Consequently, the status of aquatic life in this region remains uncertain. Addressing this concern, the latest Arkansas Wildlife Action Plan emphasizes the necessity of distribution and population data to guide conservation efforts for Species of Greatest Conservation Need …

The Center For Creative Conservation: Fostering Novel Collaborations For Regional Sustainability, Sara J. Breslow, Joshua Lawler, Julian Olden, Spencer Wood

Salish Sea Ecosystem Conference

Broad environmental and social forces are affecting our regional ecosystems and impacting the communities who depend on them in diverse ways. Addressing these complex social-ecological challenges necessitates growth in the collective wisdom of society. The Center for Creative Conservation at the University of Washington is addressing this need by promoting innovative solutions to complex environmental problems through fostering collaborations across broadly diverse disciplines, sectors, and communities. We strive to learn and apply best practices of transdisciplinarity, meaning authentically engaging different modes of knowing toward novel and integrated ideas, methods, and applications. For example, we convene medical researchers with ecologists, urban …

Noaa Rockfish Recovery Management And Research In The Salish Sea, Washington, James R. (James Robert) Selleck, Dan Tonnes

Salish Sea Ecosystem Conference

Rockfish are a long-lived species group that provide an important function for the food web dynamics in the Salish Sea, as both a mid-level trophic predator and important prey source, and they hold cultural significance to the region. Rockfish are comprised of over 25 different species locally, and over 60 species from California to Alaska. Many species experienced declines since the 1980’s, and two species are listed in the Salish Sea under ESA as threatened (yelloweye) or endangered (Bocaccio). Different species occupy a range of habitat types, from deep-water rock piles and hard bottom substrate, to nearshore kelp forests and …

Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …

The Fine-Scale Habitat Use Of Risso’S Dolphins Off Bardsey Island, Cardigan Bay (Uk), Marijke N. De Boer, Sonja Eisfeld, Mark P. Simmonds

Mark P. Simmonds, OBE

The main objectives of this study were (1) to estimate the population size of Risso’s dolphins off Bardsey Island using mark-recapture techniques (De Boer et al., 2013); and (2) to study habitat-use in relation to fine-scale oceanographic features. This work provides preliminary information on the habitat-use of Risso’s dolphins and will benefit future studies, along with the development of effective conservation measures for this species throughout the region.
