Abstract Connectivity conservation is an emergent approach to counteracting landscape fragmentation and enhancing resilience climate change at local, national, global scales. While policy that promotes connectivity advancing, there has been no systematic, evidence-based study assesses whether plans (CCPs) resulted in outcomes, identifies specific plan attributes may favor successful implementation. To fill this gap, we gathered 263 terrestrial CCPs from around the world, characterized of 109...
Identifying drivers of contact rates among individuals is critical to understanding disease dynamics and implementing targeted control measures. We studied the interaction patterns 149 female elk ( Cervus canadensis ) distributed across five different regions western Wyoming over three years, defining a as an approach within one body length (∼2 m). Using hierarchical models that account for correlations individuals, pairs, groups, we found pairwise group declined by factor sizes increased...
Mantel-based tests have been the primary analytical methods for understanding how landscape features influence observed spatial genetic structure. Simulation studies examining approaches highlighted major challenges associated with use of such and fueled debate on when Mantel test is appropriate genetics studies. We aim to provide some clarity in this using spatially explicit, individual-based, simulations examine effects following performance methods: (1) configuration, (2) nonequilibrium,...
Abstract High seroprevalance for Brucella abortus among elk on Wyoming feedgrounds suggests that supplemental feeding may influence parasite transmission and disease dynamics by altering the rate at which contact infectious materials in their environment. We used proximity loggers video cameras to estimate rates of elk‐to‐fetus (the primary source brucellosis transmission) during winter feeding. compared high‐density low‐density (LD) treatments provided same total amount food distributed...
Landscape genetic studies based on neutral markers have contributed to our understanding of the influence landscape composition and configuration gene flow variation. However, potential for species adapt changing landscapes will depend how natural selection influences adaptive We demonstrate resistance models can be combined with simulations incorporating explore spread variation is affected by characteristics, using desert bighorn sheep (Ovis canadensis nelsoni) in three differing regions...
Assessments of organisms' vulnerability to potential climatic shifts are increasingly common. Such assessments often conducted at the species level and focused primarily on magnitude anticipated climate change (i.e., exposure). However, wildlife management would benefit from population-level that also incorporate measures local or regional for organismal adaptation change. Estimates genetic diversity, gene flow, landscape connectivity can address this need complement exposure estimates...
ABSTRACT Translocation is an important management tool that has been used for >50 years in Arizona, USA, to increase bighorn sheep ( Ovis canadensis ) population densities and restore herds suitable habitat throughout their historical range. Yet, translocation can also alter the underlying genetic diversity spatial structure of managed wildlife species beneficial or detrimental ways. To evaluate long‐term effect actions on sheep, we characterized statewide using microsatellite...
Abstract The United States Forest Service promulgated new planning regulations under the National Management Act in 2012 (i.e., Planning Rule). These include first requirements U.S. public land management history for Forests to evaluate, protect, and/or restore ecological connectivity as they revise their plans. Data and resource limitations make single‐species, functional analyses myriad species that occur within 78 million ha manages implausible. We describe an approach relies on freely...
Abstract The intersection of wildlife and people on roads raises two critical issues: the barrier mortality effects risks to from animal‐vehicle collisions (AVCs). Road mitigation decisions are typically made at discretion transportation departments that mandated primarily address motorist safety. Therefore, prioritization road sections for currently focuses identification spatial clusters AVCs. We sought understand if AVC align with multispecies connectivity across accurately identify...
Abstract Assessments of the potential responses animal species to climate change often rely on correlations between long-term average temperature or precipitation and species’ occurrence abundance. Such assessments do not account for predictive capacity either extremes variability indirect effects as mediated by plant phenology. By contrast, we projected wildlife in desert grasslands southwestern United States future means, extremes, changes timing magnitude primary productivity. We used...
Introduction Terrestrial species in riverine ecosystems face unique constraints leading to diverging patterns of population structure, connectivity, and disease dynamics. Desert bighorn sheep ( Ovis canadensis nelsoni ) Grand Canyon National Park, a large native the southwestern USA, offer opportunity evaluate processes remote system with ongoing anthropogenic impacts. We integrated non-invasive, invasive, citizen-science methods address questions on abundance, distribution, status, genetic...
Protected areas are one of the most effective means by which biodiversity is conserved, but often criticized for either neglecting importance local communities or sacrificing conservation objectives political expedience. In United States, federal protected can be designated via a democratic legislation process executive action, allows comparison ecological and sociopolitical context these top-down bottom-up processes. We compared resulting from congressional designation vs. presidential with...
ABSTRACT American beaver ( Castor canadensis ) have been translocated for population restoration, reduction of human‐wildlife conflict, and enhancement ecosystem function. Yet few studies assessed dispersal beaver, making it difficult to determine at what scale translocations are appropriate. Genetic can provide inferences about gene flow, thus dispersal. We used a landscape genetic approach evaluate whether features influenced flow among in the Coast Range western Oregon, USA, using samples...
