Low Diversity in theMitogenome of Sperm Whales Revealed by Next-Generation Sequencing

Creator:: Alexander, Alana, Steel, Debbie, Slikas, Beth, Hoekzema, Kendra, Carraher, Colm, Parks, Matthew, Cronn, Richard, and Baker, C. Scott
Abstract:: Large population sizes and global distributions generally associate with high mitochondrial DNA control region (CR) diversity. The sperm whale (Physeter macrocephalus) is an exception, showing low CR diversity relative to other cetaceans; however, diversity levels throughout the remainder of the sperm whale mitogenome are unknown. We sequenced 20 mitogenomes from...

Large-scale macroinvertebrate assemblage patterns from least-disturbed wadeable stream sites across the 48 contiguous US states

Creator:: Gerth, W. J., Herlihy, A. T., and Sifneos, J. C.
Abstract:: We quantified the patterns in macroinvertebrate assemblages and their associated environmental gradients from 457 least-disturbed wadeable stream sites across the 48 contiguous United States sampled as part of US EPA’s National Wadeable Stream Assessment. The majority of the variation in assemblage composition at the finest taxonomic resolution was related to...

Evidence for geomagnetic imprinting as a homing mechanism in Pacific salmon

Creator:: Putnam, Nathan F., Lohmann, Kenneth J., Putnam, Emily M., Quinn, Thomas P., Klimley, A. Peter, and Noakes, David L. G.
Abstract:: In the final phase of their spawning migration, Pacific salmon use chemical cues to identify their home river, but how they navigate from the open ocean to the correct coastal area has remained enigmatic [1]. To test the hypothesis that salmon imprint on the magnetic field that exists where they...

Nighttime foraging by deep diving echolocating odontocetes off the Hawaiian islands of Kauai and Ni’ihau as determined by passive acoustic monitors

Creator:: Au, Whitlow W. L., Giorli, Giacomo, Chen, Jessica, Copeland, Adrienne, Lammers, Marc, Richlen, Michael, Jarvis, Susan, Morrissey, Ronald, Moretti, David, and Klinck, Holger
Abstract:: Remote autonomous ecological acoustic recorders (EARs) were deployed in deep waters at five locations around the island of Kauai and one in waters off Ni'ihau in the main Hawaiian island chain. The EARs were moored to the bottom at depths between 400 and 800 m. The data acquisition sampling rate...

Female elk contacts are neither frequency nor density dependent

Creator:: Cross, P. C., Creech, Tyler G., Ebinger, M. R., Manlove, K., Irvine, K., Henningsen, J., Roberson, J., Scurlock, B. M., and Creel, S.
Abstract:: 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 different regions of western Wyoming over three years, defining a contact as an approach within one body length...

Defining quantitative stream disturbance gradients and the additive role of habitat variation to explain macroinvertebrate taxa richness

Creator:: Ligeiro, Raphael, Hughes, Robert M., Kaufmann, Philip R., Macedo, Diego R., Firmiano, Kele R., Ferreira, Wander R., Oliveira, Deborah, Melo, Adriano S., and Callisto, Marcos
Abstract:: Most studies dealing with the use of ecological indicators and other applied ecological research rely on some definition or concept of what constitutes least-, intermediate- and most-disturbed condition. Currently, most rigorous methodologies designed to define those conditions are suited to large spatial extents (nations, ecoregions) and many sites (hundreds to...

Modelling dendritic ecological networks in space: an integrated network perspective

Creator:: Peterson, Erin E., Ver Hoef, Jay M., Isaak, Dan J., Falke, Jeffrey A., Fortin, Marie-Jos ee, Jordan, Chris E., McNyset, Kristina, Monestiez, Pascal, Ruesch, Aaron S., Sengupta, Aritra, Som, Nicholas, Steel, E. Ashley, Theobald, David M., Torgersen, Christian E., and Wenger, Seth J.
Abstract:: Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships...

Disentangling bottom-up and top-down effects on survival during early ocean residence in a population of Chinook salmon (Oncorhynchus tshawytscha)

Creator:: Miller, Jessica A., Teel, David J., Baptista, Antonio, and Morgan, Cheryl A.
Abstract:: We evaluated the relative importance of "bottom-up" (production-limited) and "top-down" (predator-mediated) processes during early marine residence in a population of Chinook salmon (Oncorhynchus tshawytscha) from the upper Columbia River, USA. We examined length, mass, and condition index of age-0 juveniles collected in the ocean during June and September across 11...

Survival and Home-range Size of Northern Spotted Owls in Southwestern Oregon

Creator:: Schilling, Jason W., Dugger, Katie M., and Anthony, Robert G.
Abstract:: In the Klamath province of southwestern Oregon, Northern Spotted Owls (Strix occidentalis caurina) occur in complex, productive forests that historically supported frequent fires of variable severity. However, little is known about the relationships between Spotted Owl survival and home-range size and the characteristics of fire-prone, mixed-conifer forests of the Klamath...

The idiosyncrasies of place: geographic variation in the climate–distribution relationships of the American pika

Creator:: Jeffress, Mackenzie R., Rodhouse, Thomas J., Ray, Chris, Wolff, Susan, and Epps, Clinton W.
Abstract:: 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 climate change on biodiversity. Bioclimatic niche models provide compelling evidence that many species will experience range...
