Redefining reproductive success in songbirds: Moving beyond the nest success paradigm
Henry M. Streby, Jeanine M. Refsnider, David E. Andersen
2014, The Auk (131) 718-726
One of the most commonly estimated parameters in studies of songbird ecology is reproductive success, as a measure of either individual fitness or population productivity. Traditionally, the “success” in reproductive success refers to whether, or how many, nestlings leave nests. Here, we advocate that “reproductive success” in songbirds be redefined...
Ongoing drought-induced uplift in the western United States.
Adrian Antal Borsa, Duncan Carr Agnew, Daniel R. Cayan
2014, Science (345) 1587-1590
The western United States has been experiencing severe drought since 2013. The solid earth response to the accompanying loss of surface and near-surface water mass should be a broad region of uplift. We use seasonally adjusted time series from continuously operating global positioning system stations to measure this uplift, which...
Evaluation of wave runup predictions from numerical and parametric models
Hilary F. Stockdon, David M. Thompson, Nathaniel G. Plant, Joseph W. Long
2014, Coastal Engineering (92) 1-11
Wave runup during storms is a primary driver of coastal evolution, including shoreline and dune erosion and barrier island overwash. Runup and its components, setup and swash, can be predicted from a parameterized model that was developed by comparing runup observations to offshore wave height, wave period, and local beach...
Does age matter? The influence of age on response rates in a mixed-mode survey
Larry M. Gigliotti, Alia Dietsch
2014, Human Dimensions of Wildlife: An International Journal (19) 280-287
The appeal of cost savings and faster results has fish and wildlife management agencies considering the use of Internet surveys instead of traditional mail surveys to collect information from their constituents. Internet surveys, however, may suffer from differential age-related response rates, potentially producing biased results if certain age groups respond...
Trouble in the aquatic world: How wildlife professionals are battling amphibian declines
Deanna H. Olson, Tara E. Chestnut
2014, The Wildlife Professional (8) 28-31
A parasitic fungus, similar to the one that caused the extinction of numerous tropical frog and toad species, is killing salamanders in Europe. Scientists first identified the fungus, Batrachochytrium salamandrivorans, in 2013 as the culprit behind the death of fire salamanders (Salamandra salamandra) in the Netherlands (Martel et al....

The effects of harvest on waterfowl populations
Evan G. Cooch, Matthieu Guillemain, G Scott Boomer, Jean-Dominique Lebreton, James D. Nichols
2014, Wildfowl (Special Issue 4) 220-276
Change in the size of populations over space and time is, arguably, the motivation for much of pure and applied ecological research. The fundamental model for the dynamics of any population is straightforward: the net change in the abundance is the simple difference between the number of individuals entering the population and the number...
Assessing the importance of terrain parameters on glide avalanche release
Erich H. Peitzsch, Jordy Hendrikx, Daniel B. Fagre
2014, Conference Paper, Proceedings of the International Snow Science Workshop
Glide snow avalanches are dangerous and difficult to predict. Despite recent research there is still a lack of understanding regarding the controls of glide avalanche release. Glide avalanches often occur in similar terrain or the same locations annually and observations suggest that topography may be critical. Thus, to gain an...

Sharp increase in central Oklahoma seismicity 2009-2014 induced by massive wastewater injection
Kathleen M. Keranen, Geoffrey A. Abers, Matthew Weingarten, Barbara A. Bekins, Shemin Ge
2014, Science (345) 448-451
Unconventional oil and gas production provides a rapidly growing energy source; however high-producing states in the United States, such as Oklahoma, face sharply rising numbers of earthquakes. Subsurface pressure data required to unequivocally link earthquakes to injection are rarely accessible. Here we use seismicity and hydrogeological models to show that...

Can managers compensate for coyote predation of white-tailed deer?
Kelly F. Robinson, Duane R. Diefenbach, Angela K. Fuller, Jeremy E. Hurst, Christopher S. Rosenberry
2014, Journal of Wildlife Management (78) 571-579
Many studies have documented that coyotes (Canis latrans) are the greatest source of natural mortality for white-tailed deer (Odocoileus virginianus) neonates (<3 months old). With the range expansion of coyotes eastward in North America, many stakeholders are concerned that coyote predation may be affecting deer populations adversely. We hypothesized that...
