| assessing population structure and gene flow in montana wolverines (gulo gulo) using assignment-based approaches. | in north america, wolverines once occupied a continuous range from alaska southward to new mexico. in the lower 48 states, small remnant populations remain only in the northwestern united states. among these remnant populations, the montana population has the highest probability of long-term persistence given its size and proximity to healthy populations in canada. in this study, we evaluate population genetic structure and gene flow among montana wolverines using 10 polymorphic microsatellite l ... | 2003 | 14629372 |
| trade-offs and efficiencies in optimal budget-constrained multispecies corridor networks. | conservation biologists recognize that a system of isolated protected areas will be necessary but insufficient to meet biodiversity objectives. current approaches to connecting core conservation areas through corridors consider optimal corridor placement based on a single optimization goal: commonly, maximizing the movement for a target species across a network of protected areas. we show that designing corridors for single species based on purely ecological criteria leads to extremely expensive ... | 2017 | 27677418 |
| a spatial dirichlet process mixture model for clustering population genetics data. | identifying homogeneous groups of individuals is an important problem in population genetics. recently, several methods have been proposed that exploit spatial information to improve clustering algorithms. in this article, we develop a bayesian clustering algorithm based on the dirichlet process prior that uses both genetic and spatial information to classify individuals into homogeneous clusters for further study. we study the performance of our method using a simulation study and use our model ... | 2011 | 20825394 |
| wolverine gene flow across a narrow climatic niche. | wolverines (gulo gulo) are one of the rarest carnivores in the contiguous united states. effective population sizes in montana, idaho, and wyoming, where most of the wolverines in the contiguous united states exist, were calculated to be 35 (credible limits, 28 52) suggesting low abundance. landscape features that influence wolverine population substructure and gene flow are largely unknown. recent work has identified strong associations between areas with persistent spring snow and wolverine pr ... | 2009 | 19967877 |
