Greater sage-grouse vital rates after wildfire

Creator:: Foster, Lee J., Dugger, Katie M., Hagen, Christian A., and Budeau, David A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) have been subject to long-term and continuing declines in population and habitat since European settlement of western North America. Increased wildfire activity constitutes a primary threat to the species in western portions of their range, with documented declines in wildfire-affected populations. Following a 187,000-ha wildfire in...

First Direct Evidence for Natal Wintering Ground Fidelity and Estimate of Juvenile Survival in the New Zealand Southern Right Whale Eubalaena australis

Creator:: Carroll, E. L., Fewster, R. M., Childerhouse, S. J., Patenaude, N. J., Boren, L., and Baker, C. S.
Abstract:: Juvenile survival and recruitment can be more sensitive to environmental, ecological and anthropogenic factors than adult survival, influencing population-level processes like recruitment and growth rate in long-lived, iteroparous species such as southern right whales. Conventionally, Southern right whales are individually identified using callosity patterns, which do not stabilise until 6–12...

What drives interaction strengths in complex food webs? A test with feeding rates of a generalist stream predator

Creator:: Preston, Daniel L., Henderson, Jeremy S., Falke, Landon P., Segui, Leah M., Layden, Tamara J., and Novak, Mark
Abstract:: Describing the mechanisms that drive variation in species interaction strengths is central to understanding, predicting, and managing community dynamics. Multiple factors have been linked to trophic interaction strength variation, including species densities, species traits, and abiotic factors. Yet most empirical tests of the relative roles of multiple mechanisms that drive...

Resilience and resistance in sagebrush ecosystems are associated with seasonal soil temperature and water availability

Creator:: Roundy, Bruce A., Chambers, Jeanne C., Pyke, David A., Miller, Richard F., Tausch, Robin J., Schupp, Eugene W., Rau, Ben, and Gruell, Trevor
Abstract:: Invasion and dominance of exotic grasses and increased fire frequency threaten native ecosystems worldwide. In the Great Basin region of the western United States, woody and herbaceous fuel treatments are implemented to decrease the effects of wildfire and increase sagebrush (Artemisia spp.) ecosystem resilience to disturbance and resistance to exotic...

Patterns and Variation in Benthic Biodiversity in a Large Marine Ecosystem

Creator:: Piacenza, Susan E., Barner, Allison K., Benkwitt, Cassandra E., Boersma, Kate S., Cerny-Chipman, Elizabeth B., Ingeman, Kurt E., Kindinger, Tye L., Lee, Jonathan D., Lindsley, Amy J., Reimer, Jessica N., Rowe, Jennifer C., Shen, Chenchen, Thompson, Kevin A., Thurman, Lindsey L., and Heppell, Selina S.
Abstract:: While there is a persistent inverse relationship between latitude and species diversity across many taxa and ecosystems, deviations from this norm offer an opportunity to understand the conditions that contribute to large-scale diversity patterns. Marine systems, in particular, provide such an opportunity, as marine diversity does not always follow a...

Do gray whales count calories? Comparing energetic values of gray whale prey across two different feeding grounds in the eastern North Pacific

Creator:: Hildebrand, Lisa, Bernard, Kim S., and Torres, Leigh G.
Abstract:: Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy. We assessed the energetic value of the six most...

The Effect of Novel Research Activities on Long-term Survival of Temporarily Captive Steller Sea Lions (Eumetopias jubatus)

Creator:: Shuert, Courtney, Horning, Markus, and Mellish, Jo-Ann
Abstract:: Two novel research approaches were developed to facilitate controlled access to, and long-term monitoring of, juvenile Steller sea lions for periods longer than typically afforded by traditional fieldwork. The Transient Juvenile Steller sea lion Project at the Alaska SeaLife Center facilitated nutritional, physiological, and behavioral studies on the platform of...

Survival of Immunoglobulins from Human Milk to Preterm Infant Gastric Samples at 1, 2, and 3 h Postprandial

Creator:: Demers-Mathieu, Veronique, Underwood, Mark A., Beverly, Robert L., and Dallas, David C.
Abstract:: Background: Human milk immunoglobulins (Ig) are an important support for the naive infant immune system; yet the extent to which these proteins survive within the infant digestive tract, particularly for preterm infants, is poorly studied. Objectives: Our objective was to evaluate the survival of human milk Igs in the preterm...

Quantifying predator dependence in the functional response of generalist predators

Creator:: Novak, Mark, Wolf, Christopher, Coblentz, Kyle E., and Shepard, Isaac D.
Abstract:: A long-standing debate concerns how functional responses are best described. Theory suggests that ratio dependence is consistent with many food web patterns left unexplained by the simplest prey-dependent models. However, for logistical reasons, ratio dependence and predator dependence more generally have seen infrequent empirical evaluation and then only so in...

Boundaries Crossed and Boundaries Made: The Productive Tension Between Learning and Influence in Transformative Networks

Creator:: Risien, Julie and Goldstein, Bruce Evan
Abstract:: We present an in-depth case study of a learning network that aims to transform infrastructure and practice across the research enterprise to advance societal impacts. The theory of social morphogenesis guides our processual qualitative analysis of the network. We describe how different types of boundary work, both building and navigating...
