This study was initiated to assess the genetic status of the remnant population of Melicope zahlbruckneri–a critically endangered...
Movement reveals scale dependence in habitat selection of a large ungulate
Joseph Northrup, Charles R. Anderson Jr., Mevin Hooten, George Wittemyer
2016, Ecological Applications (26) 2746-2757
Ecological processes operate across temporal and spatial scales. Anthropogenic disturbances impact these processes, but examinations of scale dependence in impacts are infrequent. Such examinations can provide important insight to wildlife–human interactions and guide management efforts to reduce impacts. We assessed spatiotemporal scale dependence in habitat selection of mule deer (Odocoileus...

Bryan D. Downing, Brian A. Bergamaschi, Carol Kendall, Tamara E. C. Kraus, Kate J. Dennis, Jeffery A. Carter, Travis von Dessonneck
2016, Environmental Science & Technology (50) 13387-13396
Stable isotopes present in water (δ2H, δ18O) have been used extensively to evaluate hydrological processes on the basis of parameters such as evaporation, precipitation, mixing, and residence time. In estuarine aquatic habitats, residence time (τ) is a major driver of biogeochemical processes, affecting trophic subsidies and conditions in fish-spawning habitats....
Response of fish assemblages to decreasing acid deposition in Adirondack Mountain lakes
Barry P. Baldigo, Karen Roy, Charles T. Driscoll
2016, NYSERDA Report 17-01
The CAA and other federal regulations have clearly reduced emissions of NOx and SOx, acidic deposition, and the acidity and toxicity of waters in the ALTM lakes, but these changes have not triggered widespread recovery of brook trout populations or fish communities. The lack of detectable biological recovery appears to...

Caleb P. Roberts, James W. Cain III, Robert D. Cox
2016, Wildlife Society Bulletin (40) 764-771
The increasing use of Global Positioning System (GPS) collars in habitat selection studies provides large numbers of precise location data points with reduced field effort. However, inclusion of activity sensors in many GPS collars also grants the potential to remotely estimate behavioral state. Thus, only using GPS collars to collect...
A possible source mechanism of the 1946 Unimak Alaska far-field tsunami, uplift of the mid-slope terrace above a splay fault zone
Roland E. von Huene, John J. Miller, Dirk Klaeschen, Peter Dartnell
2016, Pure and Applied Geophysics (173) 4189-4201
In 1946, megathrust seismicity along the Unimak segment of the Alaska subduction zone generated the largest ever recorded Alaska/Aleutian tsunami. The tsunami severely damaged Pacific islands and coastal areas from Alaska to Antarctica. It is the charter member of “tsunami” earthquakes that produce outsized far-field tsunamis for the recorded magnitude....
Tree regeneration by seed in bottomland hardwood forests: A review
Whitney A. Kroschel, Sammy L. King, Richard F. Keim
2016, Southeastern Naturalist (15) 42-60
Bottomland hardwood forests (BLH) are found in temperate, humid regions of the southeastern US, primarily on alluvial floodplains adjacent to rivers. Altered hydrology in rivers and floodplains has caused changes in stand development and species composition of BLHs. We hypothesize that the driving mechanisms behind these changes are related to...
