Intra‐ and inter‐annual variation in gray whale body condition on a foraging ground

Creator:

Soledade Lemos, Leila, Burnett, Jonathan D., Chandler, Todd E., Sumich, James L., and Torres, Leigh G.

Abstract:

Baleen whales store energy gained on foraging grounds to support reproduction and other metabolic needs while fasting for long periods during migration. Whale body condition can be used to monitor foraging success, and thus better understand and anticipate individual‐ and population‐level trends in reproduction and survival. We assessed the body...

Article
The relative contribution of climate to changes in lesser prairie-chicken abundance

Creator:

Ross, Beth E., Haukos, David, Hagen, Christian, and Pitman, James

Abstract:

Managing for species using current weather patterns fails to incorporate the uncertainty associated with future climatic conditions; without incorporating potential changes in climate into conservation strategies, management and conservation efforts may fall short or waste valuable resources. Understanding the effects of climate change on species in the Great Plains of...

Long-distance migration of prey synchronizes demographic rates of top predators across broad spatial scales

Creator:

Ward, E. J., Dahlheim, M. E., Waite, J. M., Emmons, C. K., Marshall, K. N., Chasco, B. E., and Balcomb, K. C. III

Abstract:

Reproductively and geographically isolated populations of predators may be synchronized by a phenomenon known as the Moran effect—specifically if they exhibit common responses to external processes, such as climate, density dependence (parasites, disease), or prey. Prey has the ability to synchronize predators if geographically isolated predator populations target the same...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:

Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.

Abstract:

Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

Factors affecting female space use in ten populations of prairie chickens

Creator:

Winder, Virginia L., Carrlson, Kaylan M., Gregory, Andrew J., Hagen, Christian A., Haukos, David A., Kesler, Dylan C., Larsson, Lena C., Matthews, Ty W., McNew, Lance B., Patten, Michael A., Pitman, Jim C., Powell, Larkin A., Smith, Jennifer A., Thompson, Tom, Wolfe, Donald H., and Sandercock, Brett K.

Abstract:

Conservation of wildlife depends on an understanding of the interactions between animal movements and key landscape factors. Habitat requirements of wide-ranging species often vary spatially, but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated patterns of space use for 10 populations of two closely...

Effect of age-based and environment-based cues on reproductive investment in Gambusia affinis

Creator:

Billman, Eric J. and Belk, Mark C.

Abstract:

We examined the multivariate life-history trajectories of age 0 and age 1 female Gambusia affinis to determine relative effects of age-based and environment-based cues on reproductive investment. Age 0 females decreased reproductive investment prior to the onset of fall and winter months, while age 1 females increased reproductive investment as...

Elemental Markers in Elasmobranchs: Effects of Environmental History and Growth on Vertebral Chemistry

Creator:

Smith, Wade D., Miller, Jessica A., and Heppell, Selina S.

Abstract:

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 can be inferred from the elemental signatures within the vertebrae of elasmobranchs (sharks, skates, rays) has not been...

A Multi-Year Longitudinal Study of Water Quality Parameters in Four Salmon-Bearing and Recreational Streams on Mount Hood, Oregon

Creator:

Wasowski, Ronald, Alexander, David, Kolmes, Steven, Banet, Nathan, Card, Amy, Haines, Morgan, Kolmes, Elijah, Northcutt, Kelly, Roemer, Derek, and Webber, Sarah

Abstract:

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 for recreational users and anchor habitat for Pacific Salmon. Temperatures were recorded using micro -T temperature loggers...

Nested scales of spatial heterogeneity in juvenile walleye pollock Theragra chalcogramma in the southeastern Bering Sea

Creator:

Benoit-Bird, Kelly J., McIntosh, Neal E., and Heppell, Scott A.

Abstract:

We sought to characterize the distribution of juvenile walleye pollock Theragra chalcogramma in an area of intense predator-prey interactions and to describe habitat features that lead to their observed distributions. The distribution of juvenile walleye pollock around the Pribilof Islands in the southeastern Bering Sea in 2008 and 2009 was...

Short-term responses of native bees to livestock and implications for managing ecosystem services in grasslands

Creator:

Kimoto, Chiho, DeBano, Sandra J., Thorp, Robbin W., Taylor, Robert V., Schmalz, Heidi, DelCurto, Timothy, Johnson, Tracey, Kennedy, Patricia L., and Rao, Sujaya

Abstract:

Rangelands are significant providers of ecosystem services in agroecosystems world‐wide. Yet few studies have investigated how different intensities of livestock grazing impact one important provider of these ecosystem services—native bees. We conducted the first large‐scale manipulative study on the effect of a gradient of livestock grazing intensities on native bees...
