Boal, Clint W.; Dykstra, Cheryl R.; Conway, Courtney J. Assessing historical and projected carbon balance of Alaska: A synthesis of results and policy/management implications
We summarize the results of a recent interagency assessment of land carbon dynamics in Alaska, in which carbon dynamics were estimated for all major terrestrial and aquatic ecosystems for the historical period (1950–2009) and a projection period (2010–2099). Between 1950 and 2009, upland and wetland (i.e., terrestrial) ecosystems of the state...

Scott; Striegl, Robert G.; Wylie, Bruce K.; Zhou, Xiaoping; Zhuang, Qianlai; Zhu, Zhiliang Fitness consequences of interspecific nesting associations among cavity-nesting birds
Interspecific aggregations of prey may provide benefits by mitigating predation risk, but they can also create costs if they increase competition for resources or are more easily detectable by predators. Variation in predation risk and resource availability may influence the occurrence and fitness effects of aggregating in nature. Yet tests of...
Mouton, James C.; Martin, Thomas E. Long-term spotlight surveys of American alligators in Mississippi, USA
Accurate population estimates and assessments of trajectory are an essential part of harvest management for game species and conservation action plans for protected species. Long-term monitoring can lead to ecological understanding by identifying biotic and abiotic drivers of population dynamics. Spotlight surveys are a widely used method to...
Strickland, Bradley A.; Vilella, Francisco; Flynt, Ricky D. What is the value of wild bee pollination for wild blueberries and cranberries, and who values it?
Pollinator conservation efforts and growing interest in wild bee pollination have increased markedly in the last decade, making it increasingly important to have clear and practical estimates of the value of pollinators to agriculture. We used agricultural statistics, socio-economic producer surveys, and agronomic field research data to estimate...

Evaluation of key scientific issues in the report, “State of the mountain lion—A call to end trophy hunting of America’s lion”
In their recently published report, State of the Mountain Lion: A Call to End Trophy Hunting of America’s Lion, the Humane Society of the United States suggested that mountain lion (Puma concolor) hunting should be abolished in the United States. The report claims this recommendation is based on scientific arguments that demonstrate the...
Cain, James W.; Mitchell, Michael S. Forecasting effects of angler harvest and climate change on smallmouth bass abundance at the southern edge of their range
Climate change will affect stream systems in numerous ways over the coming century. Globally, streams are expected to experience changes in temperature and flow regime. Previous work has indicated that these changes will likely affect fish distributions, but little work has been conducted examining population level effects of climate change on...

An individual-based model for predicting dynamics of a newly established Mexican wolf (Canis lupus baileyi) population—Final report
Project SummaryThe Mexican wolf recovery team proposed to establish other populations of Mexican wolves (Canis lupus baileyi) in the Southwest (U.S. Fish and Wildlife Service, 1982). We were tasked to conduct an extensive simulation modeling exercise to determine release strategies (in conjunction with management actions) that best predict...
Gedir, Jay V.; Cain, James W. Nest tree use by Southern flying squirrels in fragmented midwestern landscapes
Southern flying squirrels (Glaucomys volans; SFS) nest in naturally formed cavities in snags and hardwoods found in mature, oak (Quercus spp.)–hickory (Carya spp.) forests. Intensive forest fragmentation of the Midwest United States limits the number of available nesting trees. We quantified annual nest‐site selection patterns by...
Zweep, James S.; Jacques, Christopher N.; Jenkins, Sean E.; Klaver, Robert W.; Dubay, Shelli A. Piscivore diet shifts and trophic level change after Alewife establishment in Lake Champlain
Invasions and deliberate introductions of new prey species are likely to affect prey choice and trophic level of resident predators. Rainbow Smelt (Osmerus mordax) and Alewife (Alosa pseudoharengus) are common prey fish species in lakes throughout North America either as native or non‐native species. The establishment of Alewife in the 2000s in a...
Simonin, Paul W.; Rudstam, Lars G.; Parrish, Donna; Pientka, Bernard; Sullivan, Patrick J. The influence of angler values, involvement, catch orientation, satisfaction, agency trust, and demographics on support for habitat protection and restoration versus stocking in publicly managed waters
Resource managers benefit from knowledge of angler support for fisheries management strategies. Factors including angler values (protection, utilitarian, and dominance), involvement (attraction, centrality, social, identity affirmation, and expression), catch-related motivations (catching some, many, and big fish, and keeping fish), satisfaction,...
Schroeder, Susan A.; Fulton, David C.; Altena, Eric; Baird, Heather; Dieterman, Douglas J.; Jennings, Martin Effects of temperature and precipitation on grassland bird nesting success as mediated by patch size
Grassland birds are declining faster than any other bird guild across North America. Shrinking ranges and population declines are attributed to widespread habitat loss and increasingly fragmented landscapes of agriculture and other land uses that are misaligned with grassland bird conservation. Concurrent with habitat loss and degradation,...
