Ewan A Macdonald, Samuel A Cushman, Erin L Landguth, Andrew J Hearn, Yadvinder Malhi, David W Macdonald,

Habitat loss is the greatest threat to biodiversity in Borneo, and to anticipate and combat its effects it is important to predict the pattern of loss and its consequences. Borneo is a region of extremely high biodiversity from which forest is being lost faster than in any other. The little-known ... Read more >>

Spatial genetic structure in American black bears (Ursus americanus): female philopatry is variable and related to population history.

Thea V Kristensen, Emily E Puckett, Erin L Landguth, Jerrold L Belant, John T Hast, Colin Carpenter, Jaime L Sajecki, Jeff Beringer, Myron Means, John J Cox, Lori S Eggert, Don White, Kimberly G Smith,

Previously, American black bears (Ursus americanus) were thought to follow the pattern of female philopatry and male-biased dispersal. However, recent studies have identified deviations from this pattern. Such flexibility in dispersal patterns can allow individuals greater ability to acclimate to changing environments. We explored dispersal and spatial genetic relatedness patterns ... Read more >>

A comparison of regression methods for model selection in individual-based landscape genetic analysis.

Andrew J Shirk, Erin L Landguth, Samuel A Cushman,

Anthropogenic migration barriers fragment many populations and limit the ability of species to respond to climate-induced biome shifts. Conservation actions designed to conserve habitat connectivity and mitigate barriers are needed to unite fragmented populations into larger, more viable metapopulations, and to allow species to track their climate envelope over time. ...

Spatially Heterogeneous Environmental Selection Strengthens Evolution of Reproductively Isolated Populations in a Dobzhansky-Muller System of Hybrid Incompatibility.

Samuel A Cushman, Erin L Landguth,

Within-species hybrid incompatibility can arise when combinations of alleles at more than one locus have low fitness but where possession of one of those alleles has little or no fitness consequence for the carriers. Limited dispersal with small numbers of mate potentials alone can lead to the evolution of clusters ... Read more >>

Simulating the spread of selection-driven genotypes using landscape resistance models for desert bighorn sheep.

Tyler G Creech, Clinton W Epps, Erin L Landguth, John D Wehausen, Rachel S Crowhurst, Brandon Holton, Ryan J Monello,

Landscape genetic studies based on neutral genetic markers have contributed to our understanding of the influence of landscape composition and configuration on gene flow and genetic variation. However, the potential for species to adapt to changing landscapes will depend on how natural selection influences adaptive genetic variation. We demonstrate how ... Read more >>

Using Landscape Genetics Simulations for Planting Blister Rust Resistant Whitebark Pine in the US Northern Rocky Mountains.

Erin L Landguth, Zachary A Holden, Mary F Mahalovich, Samuel A Cushman,

Recent population declines to the high elevation western North America foundation species whitebark pine, have been driven by the synergistic effects of the invasive blister rust pathogen, mountain pine beetle (MPB), fire exclusion, and climate change. This has led to consideration for listing whitebark pine (WBP) as a threatened or ... Read more >>

Dispersal responses override density effects on genetic diversity during post-disturbance succession.

Annabel L Smith, Erin L Landguth, C Michael Bull, Sam C Banks, Michael G Gardner, Don A Driscoll,

Dispersal fundamentally influences spatial population dynamics but little is known about dispersal variation in landscapes where spatial heterogeneity is generated predominantly by disturbance and succession. We tested the hypothesis that habitat succession following fire inhibits dispersal, leading to declines over time in genetic diversity in the early successional gecko Nephrurus ... Read more >>

Implications of recurrent disturbance for genetic diversity.

Ian D Davies, Geoffrey J Cary, Erin L Landguth, David B Lindenmayer, Sam C Banks,

Exploring interactions between ecological disturbance, species' abundances and community composition provides critical insights for ecological dynamics. While disturbance is also potentially an important driver of landscape genetic patterns, the mechanisms by which these patterns may arise by selective and neutral processes are not well-understood. We used simulation to evaluate the ... Read more >>

Detecting spatial genetic signatures of local adaptation in heterogeneous landscapes.

Brenna R Forester, Matthew R Jones, Stéphane Joost, Erin L Landguth, Jesse R Lasky,

The spatial structure of the environment (e.g. the configuration of habitat patches) may play an important role in determining the strength of local adaptation. However, previous studies of habitat heterogeneity and local adaptation have largely been limited to simple landscapes, which poorly represent the multiscale habitat structure common in nature. ...

Clusters of incompatible genotypes evolve with limited dispersal.

Erin L Landguth, Norman A Johnson, Samuel A Cushman,

Theoretical and empirical studies have shown heterogeneous selection to be the primary driver for the evolution of reproductively isolated genotypes in the absence of geographic barriers. Here, we ask whether limited dispersal alone can lead to the evolution of reproductively isolated genotypes despite the absence of any geographic barriers or ... Read more >>

Evaluating sample allocation and effort in detecting population differentiation for discrete and continuously distributed individuals

Erin L Landguth, Michael K Schwartz,

One of the most pressing issues in spatial genetics concerns sampling. Traditionally, substructure and gene flow are estimated for individuals sampled within discrete populations. Because many species may be continuously distributed across a landscape without discrete boundaries, understanding sampling issues becomes paramount. Given large-scale, geographically broad conservation efforts, researchers are ... Read more >>

Ecological speciation in the tropics: insights from comparative genetic studies in Amazonia.

Luciano B Beheregaray, Georgina M Cooke, Ning L Chao, Erin L Landguth,

Evolution creates and sustains biodiversity via adaptive changes in ecologically relevant traits. Ecologically mediated selection contributes to genetic divergence both in the presence or absence of geographic isolation between populations, and is considered an important driver of speciation. Indeed, the genetics of ecological speciation is becoming increasingly studied across a ... Read more >>

Matthew R Jones, Brenna R Forester, Ashley I Teufel, Rachael V Adams, Daniel N Anstett, Betsy A Goodrich, Erin L Landguth, Stéphane Joost, Stéphanie Manel,

Uncovering the genetic basis of adaptation hinges on the ability to detect loci under selection. However, population genomics outlier approaches to detect selected loci may be inappropriate for clinal populations or those with unclear population structure because they require that individuals be clustered into populations. An alternate approach, landscape genomics, ... Read more >>

Relative sensitivity of neutral versus adaptive genetic data for assessing population differentiation

Erin L Landguth, Niko Balkenhol,

Population differentiation is often quantified using putatively neutral genetic markers. While adaptive (i.e., selection-driven) genetic markers are becoming increasingly popular, they are mostly used for research on evolutionary processes, such as local adaptation or speciation. Here, we use simulations to evaluate the potential of adaptive genetic data for estimating population ... Read more >>
