Gray wolf exposure to emerging vector-borne diseases in Wisconsin with comparison to domestic dogs and humans Gray wolf exposure to emerging vector-borne diseases in Wisconsin with comparison to domestic dogs and humans
World-wide concern over emerging vector-borne diseases has increased in recent years for both animal and human health. In the United Sates, concern about vector-borne diseases in canines has focused on Lyme disease, anaplasmosis, ehrlichiosis, and heartworm which infect domestic and wild canids. Of these diseases, Lyme and anaplasmosis are also frequently diagnosed in humans. Gray wolves...

Growth, food consumption, and energy status of juvenile pallid sturgeon fed natural or artificial diets Growth, food consumption, and energy status of juvenile pallid sturgeon fed natural or artificial diets
Stocking of hatchery-raised fish is an important part of the pallid sturgeon Scaphirhynchus albus recovery program. In the wild, juvenile pallid sturgeon consume primarily aquatic insects, although little is known about specific dietary needs. In hatchery settings, pallid sturgeon are fed commercial diets that are formulated for salmonids. To compare food consumption, growth, and energy...

Application of activity sensors for estimating behavioral patterns Application of activity sensors for estimating behavioral patterns
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 location data belies their full capabilities...

Structured decision making as a framework for large-scale wildlife harvest management decisions Structured decision making as a framework for large-scale wildlife harvest management decisions
Fish and wildlife harvest management at large spatial scales often involves making complex decisions with multiple objectives and difficult tradeoffs, population demographics that vary spatially, competing stakeholder values, and uncertainties that might affect management decisions. Structured decision making (SDM) provides a formal decision analytic framework for evaluating difficult...

Comparison of survey techniques on detection of northern flying squirrels Comparison of survey techniques on detection of northern flying squirrels
The ability to detect a species is central to the success of monitoring for conservation and management purposes, especially if the species is rare or endangered. Traditional methods, such as live capture, can be labor-intensive, invasive, and produce low detection rates. Technological advances and new approaches provide opportunities to more effectively survey for species both in terms...

Satellite-derived temperature data for monitoring water status in a floodplain forest of the Upper Sabine River, Texas Satellite-derived temperature data for monitoring water status in a floodplain forest of the Upper Sabine River, Texas
Decreased water availability due to hydrologic modifications, groundwater withdrawal, and climate change threaten bottomland hardwood (BLH) forest communities. We used satellite-derived (MODIS) land-surface temperature (LST) data to investigate spatial heterogeneity of canopy temperature (an indicator of plant-water status) in a floodplain forest of the upper Sabine River for 2008–2014...

Upstream movements of Atlantic Salmon in the Lower Penobscot River, Maine following two dam removals and fish passage modifications Upstream movements of Atlantic Salmon in the Lower Penobscot River, Maine following two dam removals and fish passage modifications
The Penobscot River Restoration Project (PRRP), to be completed in 2016, involved an extensive plan of dam removal, increases in hydroelectric capacity, and fish passage modifications to increase habitat access for diadromous species. As part of the PRRP, Great Works and Veazie dams were removed, making Milford Dam the first impediment to federally endangered Atlantic Salmon Salmo salar...

Movement reveals scale dependence in habitat selection of a large ungulate Movement reveals scale dependence in habitat selection of a large ungulate
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...

Accurate recapture identification for genetic mark–recapture studies with error-tolerant likelihood-based match calling and sample clustering Accurate recapture identification for genetic mark–recapture studies with error-tolerant likelihood-based match calling and sample clustering
Error-tolerant likelihood-based match calling presents a promising technique to accurately identify recapture events in genetic mark–recapture studies by combining probabilities of latent genotypes and probabilities of observed genotypes, which may contain genotyping errors. Combined with clustering algorithms to group samples into sets of recaptures based upon pairwise match calls...

Individual, group, and environmental influences on helping behavior in a social carnivore Individual, group, and environmental influences on helping behavior in a social carnivore
Variation in group composition and environment can affect helping behavior in cooperative breeders. Understanding of how group size, traits of individuals within groups, food abundance, and predation risk simultaneously influence helping behavior is limited. We evaluated pup-guarding behavior in gray wolves (Canis lupus) to assess how differences in individuals, groups, and environment...

Development of a Kemp’s ridley sea turtle stock assessment model Development of a Kemp’s ridley sea turtle stock assessment model
We developed a Kemp’s ridley (Lepidochelys kempii) stock assessment model to evaluate the relative contributions of conservation efforts and other factors toward this critically endangered species’ recovery. The Kemp’s ridley demographic model developed by the Turtle Expert Working Group (TEWG) in 1998 and 2000 and updated for the binational recovery plan in 2011 was modified for use as...

Managing adaptively for multifunctionality in agricultural systems Managing adaptively for multifunctionality in agricultural systems
The critical importance of agricultural systems for food security and as a dominant global landcover requires management that considers the full dimensions of system functions at appropriate scales, i.e. multifunctionality. We propose that adaptive management is the most suitable management approach for such goals, given its ability to reduce uncertainty over time and support multiple...
