Evaluating the effect of predators on white-tailed deer: Movement and diet of coyotes
M.M. Turner, A.P. Rockhill, C.S. Deperno, J.A. Jenks, R. W. Klaver, A.R. Jarding, T.W. Grovenburg, K. H. Pollock
2011, Journal of Wildlife Management (75) 905-912
Coyotes (Canis latrans) may affect adult and neonate white-tailed deer (Odocoileus virginianus) survival and have been implicated as a contributor to the decline of deer populations. Additionally, coyote diet composition is influenced by prey availability, season, and region. Because coyote movement and diet vary by region, local data are important...
Enhanced transpiration by riparian buffer trees in response to advection in a humid temperate agricultural landscape
V. Hernandez-Santana, H. Asbjornsen, T. Sauer, T. Isenhart, K. Schilling, Ronald Schultz
2011, Forest Ecology and Management (261) 1415-1427
Riparian buffers are designed as management practices to increase infiltration and reduce surface runoff and transport of sediment and nonpoint source pollutants from crop fields to adjacent streams. Achieving these ecosystem service goals depends, in part, on their ability to remove water from the soil via transpiration. In these systems,...
Reduction of garbage in the diet of nonbreeding glaucous gulls corresponding to a change in waste management
Emily L. Weiser, Abby N. Powell
2011, Arctic (64) 220-226
Glaucous gulls (Larus hyperboreus) are major predators in the Arctic and may benefit from human development. We studied use of garbage by glaucous gulls in Barrow, Alaska, in 2007, when municipal waste was disposed of in a landfill, and in 2008, when it was incinerated. In both years, diet samples...
A perspective on nonstationarity and water management
R.M. Hirsch
2011, Journal of the American Water Resources Association (47) 436-446
This essay offers some perspectives on climate-related nonstationarity and water resources. Hydrologists must not lose sight of the many sources of nonstationarity, recognizing that many of them may be of much greater magnitude than those that may arise from climate change. It is paradoxical that statistical and deterministic approaches give...

E.S. Meier, Thomas C. Edwards Jr., Felix Kienast, M. Dobbertin, N.E. Zimmermann
2011, Journal of Biogeography (38) 371-382
During recent and future climate change, shifts in large-scale species ranges are expected due to the hypothesized major role of climatic factors in regulating species distributions. The stress-gradient hypothesis suggests that biotic interactions may act as major constraints on species distributions under more favourable growing conditions, while climatic constraints may...
Spatial variability of biotic and abiotic tree establishment constraints across a treeline ecotone in the Alaska Range
K.M. Stueve, R.E. Isaacs, L.E. Tyrrell, R.V. Densmore
2011, Ecology (92) 496-506
Throughout interior Alaska (USA), a gradual warming trend in mean monthly temperatures occurred over the last few decades (∼∼2-–4°°C). The accompanying increases in woody vegetation at many alpine treeline (hereafter treeline) locations provided an opportunity to examine how biotic and abiotic local site conditions interact to control tree establishment patterns...
Atomic weights of the elements 2009 (IUPAC technical report)
M.E. Wieser, Tyler B. Coplen
2011, Pure and Applied Chemistry (83) 359-396
The biennial review of atomic-weight determinations and other cognate data has resulted in changes for the standard atomic weights of 11 elements. Many atomic weights are not constants of nature, but depend upon the physical, chemical, and nuclear history of the material. The standard atomic weights of 10 elements having...
Does small-perimeter fencing inhibit mule deer or pronghorn use of water developments?
R.T. Larsen, John Bissonette, J.T. Flinders, A.C. Robinson
2011, Journal of Wildlife Management (75) 1417-1425
Wildlife water development can be an important habitat management strategy in western North America for many species, including both pronghorn (Antilocapra americana) and mule deer (Odocoileus hemionus). In many areas, water developments are fenced (often with small-perimeter fencing) to exclude domestic livestock and feral horses. Small-perimeter exclosures could limit wild...

2011, Journal of Wildlife Management (75) 399-412
Monitoring the response of endangered and protected species to hydrological restoration is a major component of the adaptive management framework of the Comprehensive Everglades Restoration Plan. The endangered Florida manatee (Trichechus manatus latirostris) lives at the marine-freshwater interface in southwest Florida and is likely to be affected by hydrologic restoration....
An observation of a partially albinistic zenaida macroura (Mourning Dove)
James Berdeen, David L. Otis
2011, Southeastern Naturalist (10) 185-188
Abstract Three of the 4 forms of albinism that occur in avifauna have been detected in Zenaida macroura (Mourning Dove). Albinism is rare in this species, and the incidence rate of each age and sex cohort is not well known. Consequently, we examined the pigmentation of Mourning Doves encountered in...

B.L. Brown, C.M. Swan, D.A. Auerbach, Grant E.H. Campbell, N.P. Hitt, K.O. Maloney, C. Patrick
2011, Journal of the North American Benthological Society (30) 310-327
Explaining the mechanisms underlying patterns of species diversity and composition in riverine networks is challenging. Historically, community ecologists have conceived of communities as largely isolated entities and have focused on local environmental factors and interspecific interactions as the major forces determining species composition. However, stream ecologists have long embraced a...

Holly J. Frank, M. E. Mather, Joseph M. Smith, Robert M. Muth, John T. Finn
2011, Fisheries Management and Ecology (18) 12-24
Capturing adult anadromous fish that are ready to spawn from a self sustaining population and transferring them into a depleted system is a common fisheries enhancement tool. The behaviour of these transplanted fish, however, has not been fully evaluated. The movements of stocked and native anadromous alewife, Alosa pseudoharengus (Wilson),...
