2014, Professional Paper 1801-9
The Hawaiian Volcano Observatory (HVO) was established as a natural laboratory to study volcanic processes. Since the most frequent form of volcanic activity in Hawai‘i is effusive, a major contribution of the past century of research at HVO has been to describe and quantify lava flow emplacement processes. Lava flow...

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...

Joseph Kirsch, James T. Peterson
2014, Transactions of the American Fisheries Society (143) 1358-1371
There is considerable uncertainty about the relative roles of stream habitat and landscape characteristics in structuring stream-fish assemblages. We evaluated the relative importance of environmental characteristics on fish occupancy at the local and landscape scales within the upper Little Tennessee River basin of Georgia and North Carolina. Fishes were sampled...
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...

Byron R. Berger, Richard W. Henley, Heather A. Lowers, Michael J. Pribil
2014, Journal of Volcanology and Geothermal Research (271) 70-82
Hyperacidic lakes and associated solfatara in active volcanoes are the expression of magmatic gas expansion from source to surface. Here we show for the first time, that the vein system that comprises the ~ 2 Ma high-sulfidation, Lepanto copper–gold deposit in the Mankayan district (Philippines) was associated with a contemporary hyperacidic volcanic...
Call broadcasting and automated recorders as tools for anuran surveys in a subarctic tundra landscape
R. Nicholas Mannan, Gad Perry, David E. Andersen, Clint W. Boal
2014, The Journal of North American Herpetology (1) 47-52
Relatively little is known about population ecology of anurans in arctic and subarctic tundra regions, in part because it is difficult to survey anurans in these landscapes. Anuran survey protocols developed for temperate regions have limited applicability in arctic and subarctic tundra landscapes, which may lack roads and vehicle access,...
