David R. Wilburn
2014, Scientific Investigations Report 2014-5086
Since 1998, the structure of the lead recycling industry has changed and trade patterns of the domestic lead recycling industry have shifted. Although the domestic demand for lead has remained relatively constant since 1998, production of lead has increasingly shifted to the domestic secondary lead industry. The last primary lead...

Gregory T. Wann, Cameron L. Aldridge, Clait E. Braun
2014, Population Ecology (56) 555-567
Long-term datasets for high-elevation species are rare, and considerable uncertainty exists in understanding how high-elevation populations have responded to recent climate warming. We present estimates of demographic vital rates from a 43-year population study of white-tailed ptarmigan (Lagopus leucura), a species endemic to alpine habitats in western North America. We...

Stephen Bennett, Robert K. Al-Chokhachy, Brett B. Roper, Phaedra Budy
2014, North American Journal of Fisheries Management (34) 1033-1046
Little is known about the variability in the spatial and temporal distribution of spawning potamodromous trout despite decades of research directed at salmonid spawning ecology and the increased awareness that conserving life history diversity should be a focus of management. We monitored a population of fluvial–resident Bonneville Cutthroat Trout Oncorhynchus clarkii...
Evolutionary ecology of resprouting and seeding in fire-prone ecosystems
Juli G. Pausas, Jon E. Keeley
2014, New Phytologist (204) 55-65
There are two broad mechanisms by which plant populations persist under recurrent disturbances: resprouting from surviving tissues, and seedling recruitment. Species can have one of these mechanisms or both. However, a coherent framework explaining the differential evolutionary pressures driving these regeneration mechanisms is lacking. We propose a bottom-up approach in...
