2019, Global and Planetary Change (178) 139-152
Early Eocene global climate was warmer than much of the Cenozoic and was punctuated by a series of transient warming events or ‘hyperthermals’ associated with carbon isotope excursions when temperature increased by 4–8° C. The Paleocene-Eocene Thermal Maximum (PETM, ~55 Ma) and Eocene Thermal Maximum 2 (ETM2, 53.5 Ma) hyperthermals...

2019, Book chapter, Ecosystem consequences of soil warming: Microbes, vegetation, fauna and soil biogeochemistry
The tropics are a region encircling the equator, delineated to the north by the Tropic of Cancer (23°26′14.0″N) and to the south by the Tropic of Capricorn (23°26′14.0″S). While we often think of the tropics as consistently warm and wet throughout the year, in reality, the tropics maintain a myriad of...

Quantifying risk of whale–vessel collisions across space, time, and management policies
Nathan J. Crum, Timothy A. Gowan, Andrea Krzystan, Julien Martin
2019, Ecosphere (10)
Transportation industries can negatively impact wildlife populations, including through increased risk of mortality. To mitigate this risk successfully, managers and conservationists must estimate risk across space, time, and alternative management policies. Evaluating this risk at fine spatial and temporal scales can be challenging, especially in systems where wildlife–vehicle collisions are...

North-facing slopes and elevation shape asymmetric genetic structure in the range-restricted salamander Plethodon shenandoah
KP Mulder, Nandadevi Cortes-Rodriguez, Adrianne B. Brand, Evan H. Campbell Grant, Robert C. Fleischer
2019, Ecology and Evolution (9) 5094-5105
Species with narrow environmental preferences are often distributed across fragmented patches of suitable habitat, and dispersal among subpopulations can be difficult to directly observe. Genetic data collected at population centers can help quantify gene flow, which is especially important for vulnerable species with a disjunct range. Plethodon shenandoah is a...
Patterns of acoustical activity of bats prior to and 10 years after WNS on Fort Drum Army Installation, New York
Tomás Nocera, W. Mark Ford, Alexander Silvis, Christopher A. Dobony
2019, Global Ecology and Conservation (18)
Previous acoustic surveys, netting, and count data have shown that overall bat activity patterns have shifted among most species between pre- and post-white-nose syndrome (WNS) years in much of North America where WNS has occurred. However, the significance of these changes is based on the species-specific susceptibility to WNS. We used...
