Ecologists have used a variety of comparative mensurative and manipulative experimental approaches to study the biological consequences habitat fragmentation. In this paper, we evaluate merits two major offer guidelines for selecting design. Manipulative experiments rigorously assess fragmentation effects by comparing pre- post-treatment conditions. Yet they are often constrained number practical limitations, such as difficulty in implementing large-scale treatments impracticality measuring...
Predicting population-level effects of landscape change depends on identifying factors that influence population connectivity in complex landscapes. However, most putative movement corridors and barriers have not been based empirical data. In this study, we identify by comparing patterns genetic similarity among 146 black bears (Ursus americanus), sampled across a 3,000-km(2) study area northern Idaho, with 110 landscape-resistance hypotheses. Genetic similarities were the pairwise...
Abstract Reliable interpretation of landscape genetic analyses depends on statistical methods that have high power to identify the correct process driving gene flow while rejecting incorrect alternative hypotheses. Little is known about and inference in individual‐based genetics. Our objective was evaluate causal‐modelling with partial Mantel tests analysis. We used a spatially explicit simulation model generate data across distributed population as functions several processes. This allowed...
Pool-breeding amphibian populations operate at multiple scales, from the individual pool to surrounding upland habitat clusters of pools. When metapopulation dynamics play a role in long-term viability, conservation efforts limited protection pools or even with associated may be ineffective over long term if connectivity among is not maintained. Connectivity becomes especially important and difficult assess regions where suburban sprawl rapidly increasing land development, road density,...
Abstract Populations in fragmented landscapes experience reduced gene flow, lose genetic diversity over time and ultimately face greater extinction risk. Improving connectivity is now a major focus of conservation biology. Designing effective wildlife corridors for this purpose, however, requires an accurate understanding how shape flow. The preponderance landscape resistance models generated to date, subjectively parameterized based on expert opinion or proxy measures While the relatively...
Summary Concern about the effects of habitat fragmentation has led to increasing interest in dispersal and connectivity modelling. Most modern techniques for modelling have resistance surfaces as their foundation. However, animal movement are frequently estimated without considering dispersal, despite being principal natural mechanism by which organisms move between populations. We collected Global Positioning System data over 10 years from 50 A frican lions P anthera leo (11 male natal...
Abstract Aim There is enormous interest in applying connectivity modelling to resistance surfaces for identifying corridors conservation action. However, the multiple analytical approaches used estimate and predict across have not been rigorously compared, it unclear what methods provide best inferences about population connectivity. Using a large empirical data set on puma ( Puma concolor ), we are first compare several of most common estimating validate them with dispersal data. Location...
Species distribution modeling has emerged as a foundational method to predict occurrence and suitability of species in relation environmental variables advance ecological understanding guide conservation planning. Recent research, however, shown that species-environmental relationships habitat model predictions are often nonstationary space, time context. This calls into question approaches assume global, stationary realized niche use predictive describe it. paper explores this issue by...
The ability of populations to be connected across large landscapes via dispersal is critical long-term viability for many species. One means mitigate population isolation the protection movement corridors among habitat patches. Nevertheless, utility small, narrow, linear features as has been hotly debated. Here, we argue that analysis continuously resistant allows a shift broader consideration how landscape patterns influence connectivity at scales relevant conservation. We further this...
Wolverines ( Gulo gulo ) are one of the rarest carnivores in contiguous United States. Effective population sizes Montana, Idaho, and Wyoming, where most wolverines States exist, were calculated to be 35 (credible limits, 28–52) suggesting low abundance. Landscape features that influence wolverine substructure gene flow largely unknown. Recent work has identified strong associations between areas with persistent spring snow presence range. We tested whether a dispersal model which prefer...
