Abstract With the accelerating pace of global change, it is imperative that we obtain rapid inventories status and distribution wildlife for ecological inferences conservation planning. To address this challenge, launched SNAPSHOT USA project, a collaborative survey terrestrial populations using camera traps across United States. For our first annual survey, compiled data all 50 states during 14‐week period (17 August–24 November 2019). We sampled at 1,509 trap sites from 110 arrays covering...
Studies in parts of Europe, New Zealand, and North America indicate uptake anticoagulant rodenticides (ARs) by predatory mammals to be widespread common, with proximity urban agricultural areas being an important driver exposure. Yet, little is known regarding the patterns drivers AR exposure within more forest-dominated landscapes. Across northeastern United States (US), a region spanning Pennsylvania Maine, we tested livers from 597 fisher ( Pekania pennanti ) obtained legal harvest for 11...
ABSTRACT Recently, a conservation strategy developed to restore populations of black‐tailed prairie dog ( Cynomys ludovicianus ) suggested reintroducing animals into the Chihuahuan Desert grasslands southwestern United States. Rainfall in desert habitats is lower and more variable compared rainfall near center dog's range. Additionally, peak comes months after dogs reproduce these systems. Thus, may be less prolific fluctuate than those found northerly climes. Using mark‐recapture...
Reintroductions to establish populations usually occur in locations believed have high-quality habitat maximize the potential for high population growth rates and long-term viability. Nonetheless, researchers managers may insufficient knowledge of what comprises or other requirements members a species with low sizes how determine whether these conditions are present at reintroduction sites. Locations available lack optimal but characteristics that can benefit reintroduction. allow rigorous...
Geopolitical boundaries can present challenges to wildlife conservation because of varying environmental regulations, and increasingly, the existence border barriers. As 2024, approximately 1,023 km walls (i.e., steel bollard 5.5-9.1 m tall with interstitial spaces ≤10 cm) 169 vehicle barriers variable structures designed stop vehicles but not pedestrians) exist along USA-Mexico border. Some small passages (21.5 x 27.8 were installed in few other accommodations for connectivity exist. such,...
Abstract Timing can be critical for many life history events of organisms. Consequently, the timing management activities may affect individuals and populations in numerous unforeseen ways. Translocations organisms are used to restore or expand but translocations is largely unexplored as a factor influencing population success. We hypothesized that process translocation negatively influences reproductive rates moved just before their birthing season and, therefore, releases could influence...
Human influences on natural environments are now ubiquitous but manifest in multiple and unique ways depending local communities. Attempts to control, or mediate, pests residences agriculture can impart important negative consequences systems. Secondary exposure anticoagulant rodenticides (ARs) cause numerous adverse effects wild carnivores including death. Few studies have quantified AR prevalence, investigated their pathway of exposure, associations with specific location types the...
The presence and abundance of organisms within an ecosystem often correlate with habitat variables that may have few, or unknown, functional values. Understanding the role these is especially important for occupying landscapes managed timber production containing diverse patches different quantities structures vegetation. We investigated strength associations reported in literature between small mammal generalists On industrially logged landscape northern CA, we used occupancy mark-recapture...
Habitat loss, introduced disease, and government-sponsored eradication programs have caused population declines in all 5 species of prairie dogs. Black-tailed dogs (Cynomys ludovicianus) currently occupy only about 2% an extensive geographic range (160 million hectares) were recently considered for listing under the United States Endangered Species Act. Accurate estimates density populations would be valuable estimating range-wide abundance determining threats to persistence, yet using...
Breeding systems affect the timing of reproduction, spacing patterns and social organization, individual fitnesses, population sizes. For many species, information on breeding mating is limited or untested in wild populations, resulting management actions that are incompletely informed. We used photographic data collected a reintroduced fisher (Pekania pennanti (Erxleben, 1777)) northern California, USA, to test hypotheses about system, breeding, potential for male infanticide. documented...
Animals exploring a new environment develop cognitive maps using diverse sensory input and, thereby, gain information needed to establish home ranges. Experiencing, and learning about, resources should be advantageous the resident of range while lack such put invaders into at disadvantage. Conspecifics, especially, avoid ranges one another ensure that they do not experience reduced resource availability caused by depression or depletion. Yet, encountering conspecific competitors different...
Understanding the role of landscapes managed for timber production in conservation forest-obligate species is a priority preserving ecological integrity and fostering socioeconomic wellbeing. The forest characteristics generally associated with survival, reproduction, persistence (e.g., large-diameter trees, standing dead understory vegetation, downed logs) are often believed to be at odds production. One such fisher (Pekania pennanti), mesocarnivoran (member order Carnivora) mature whose...
Managers are a strength of policy implementation in the changing and complex landscape natural resources management. We argue future managers will require additional educational emphases such as coursework evolution to confront emerging issues this dynamic profession. An emphasis on more management-oriented education at collegiate level help next cohort they face management realities. Our goal for paper is demonstrate need training evolutionary theory all professionals by (1) showing needs...
Abstract Reliable estimates of prairie dog ( Cynomys spp.) population size and distribution are critical for assessing the status dogs selecting sites to reintroduce black‐footed ferrets Mustela nigripes ). The density active burrows has commonly been used as an index abundance. Indices derived from burrow counts were developed black‐tailed C. ludovicianus ) white‐tailed leucurus dogs, but their efficacy not evaluated all species studies affirming validity with robust abundance estimators...
