Michael J. Greiner, David O. Lucchesi, Steven R. Chipps, Larry M. Gigliotti
2016, Human Dimensions of Wildlife (21) 254-263
We surveyed anglers on five community fishing lakes near Brookings, South Dakota to assess angler use and satisfaction. The community lakes attracted younger anglers when compared to statewide and national averages. Overall, satisfaction was generally high (74%) among anglers fishing community lakes. Logistic regression analysis showed that harvest rate, anglers...

Increasing temperatures in northern high latitudes are causing permafrost to thaw, making large amounts of previously frozen organic matter vulnerable to microbial decomposition. Permafrost thaw also creates a fragmented landscape of drier and wetter soil conditions that determine the amount and form (carbon dioxide (CO2), or methane (CH4)) of carbon (C) released...
Decision-making for foot-and-mouth disease control: Objectives matter
William J. M. Probert, Katriona Shea, Christopher J. Fonnesbeck, Michael C. Runge, Tim E. Carpenter, Salome Durr, M. Graeme Garner, Neil Harvey, Mark A. Stevenson, Colleen T. Webb, Marleen Werkman, Michael J. Tildesley, Matthew J. Ferrari
2016, Epidemics (15) 10-19
Formal decision-analytic methods can be used to frame disease control problems, the first step of which is to define a clear and specific objective. We demonstrate the imperative of framing clearly-defined management objectives in finding optimal control actions for control of disease outbreaks. We illustrate an analysis that can be...
Predicting arsenic in drinking water wells of the Central Valley, California
Joseph D. Ayotte, Bernard T. Nolan, JoAnn M. Gronberg
2016, Environmental Science & Technology (50) 7555-7563
Probabilities of arsenic in groundwater at depths used for domestic and public supply in the Central Valley of California are predicted using weak-learner ensemble models (boosted regression trees, BRT) and more traditional linear models (logistic regression, LR). Both methods captured major processes that affect arsenic concentrations, such as the chemical...
Reproduction in moose at their southern range limit
Joel S. Ruprecht, Kent Hersey, Konrad Hafen, Kevin L. Monteith, Nicholas J. DeCesare, Matthew J. Kauffman, Daniel R. MacNulty
2016, Journal of Mammalogy (97) 1355-1365
Reproduction is a critical fitness component in large herbivores. Biogeographic models predict that populations occurring at the edges of the range may have compromised reproductive rates because of inferior habitat at range peripheries. When reproductive rates are chronically low, ungulate populations may lack the resiliency to rebound quickly after periods...
Large herbivores surf waves of green-up during spring
Jerod Merkle, Kevin L. Monteith, Ellen O. Aikens, Matthew M. Hayes, Kent Hersey, Arthur D. Middleton, Brendan Oates, Hall Sawyer, Brandon Scurlock, Matthew J. Kauffman
2016, Proceedings of the Royal Society B: Biological Sciences (283) 1-8
The green wave hypothesis (GWH) states that migrating animals should track or ‘surf’ high-quality forage at the leading edge of spring green-up. To index such high-quality forage, recent work proposed the instantaneous rate of green-up (IRG), i.e. rate of change in the normalized difference vegetation index over time. Despite this...

Depredation of the California Ridgway’s rail: Causes and distribution
Michael L. Casazza, Cory T. Overton, Thuy-Vy D. Bui, John Y. Takekawa, Angela M. Merritt, J.M. Hull
2016, Conference Paper, Proceedings of the 27th Vertebrate Pest Conference
We studied the causes of mortality for the California Ridgway’s rail at multiple tidal marshes in the San Francisco Bay Estuary, California. We radio-marked 196 individual rails and examined the evidence from 152 recovered California Ridgway’s rail mortalities from our radio-marked sample and determined plausible cause of death from a...

Dermocystidium sp. infection in Blue Ridge Sculpin captured in Maryland
Vicki S. Blazer, Nathaniel P. Hitt, Craig D. Snyder, Erin Snook, Cynthia R. Adams
2016, Journal of Aquatic Animal Health (28) 143-149
Raised pale cysts were observed on Blue Ridge Sculpin Cottus caeruleomentum during stream fish community surveys in Catoctin Mountain Park, Maryland. When examined histologically, preserved sculpin exhibited multiple cysts containing spherical endospores with a refractile central body characteristic of Dermocystidiumspp. Cysts were not observed on the gills or internally. The...
National Park Service Vegetation Mapping Inventory Program: Natchez Trace Parkway vegetation mapping project report

2016, Natural Resource Report NPS/GULN/NRR—2016/1255
The National Park Service (NPS) Vegetation Mapping Inventory (VMI) Program is an effort to classify, describe, and map existing vegetation of national park units for the NPS Natural Resource Inventory and Monitoring (I&M) Program. The NPS VMI Program is managed by the NPS I&M Division and provides baseline vegetation information...

Ungulate browsers promote herbaceous layer diversity in logged temperate forests
Edward K. Faison, Stephen DeStefano, David R. Foster, Glenn Motzkin, Josh Rapp
2016, Ecology and Evolution (6) 4591-4602
Ungulates are leading drivers of plant communities worldwide, with impacts linked to animal density, disturbance and vegetation structure, and site productivity. Many ecosystems have more than one ungulate species; however, few studies have specifically examined the combined effects of two or more species on plant communities. We examined the extent...
Earthquake geology and paleoseismology of major strands of the San Andreas fault system
Thomas Rockwell, Katherine M. Scharer, Timothy E. Dawson
2016, Book chapter, Applied geology in California
The San Andreas fault system in California is one of the best-studied faults in the world, both in terms of the long-term geologic history and paleoseismic study of past surface ruptures. In this paper, we focus on the Quaternary to historic data that have been collected from the major strands...
Common carp disrupt ecosystem structure and function through middle-out effects
Mark A. Kaemingk, Jeffrey C. Jolley, Craig P. Paukert, David W. Willis, Kjetil R. Henderson, Richard S. Holland, Greg A. Wanner, Mark L. Lindvall
2016, Marine and Freshwater Research (68) 718-731
Middle-out effects or a combination of top-down and bottom-up processes create many theoretical and empirical challenges in the realm of trophic ecology. We propose using specific autecology or species trait (i.e. behavioural) information to help explain and understand trophic dynamics that may involve complicated and non-unidirectional trophic interactions. The common...

A long-term study of ecological impacts of river channelization on the population of an endangered fish: Lessons learned for assessment and restoration
James H. Roberts, Gregory B. Anderson, Paul L. Angermeier
2016, Water (8) 1-38
Projects to assess environmental impact or restoration success in rivers focus on project-specific questions but can also provide valuable insights for future projects. Both restoration actions and impact assessments can become “adaptive” by using the knowledge gained from long-term monitoring and analysis to revise the actions, monitoring, conceptual model, or...
Acoustic surveys of Hawaiian Hoary Bats in Kahikinui Forest Reserve and Nakula Natural Area Reserve on the Island of Maui

The Kahikinui Forest Reserve and the adjoining Nakula Natural Area Reserve (KFR-NNAR) was established in 2011 as a conservation area on the leeward slope of Haleakalā Volcano on the island of Maui to protect unique natural features and endangered species including the Hawaiian hoary bat, Lasiurus cinereus semotus. We recorded...

Groundwater quality is a concern in alluvial aquifers that underlie agricultural areas, such as in the San Joaquin Valley of California. Shallow domestic wells (less than 150 m deep) in agricultural areas are often contaminated by nitrate. Agricultural and rural nitrate sources include dairy manure, synthetic fertilizers, and septic waste....
