Contributions of landscape genetics – approaches, insights, and future potential

The focus of landscape genetics was refined to include spatially explicit research that specifically ‘quantifies the effects of landscape composition, configuration and matrix quality on gene flow and spatial genetic variation’.

Landscape Genetics

ABSTRACT Landscape genetics is a rapidly evolving interdisciplinary field that integrates approaches from population genetics and landscape ecology. In the context of habitat fragmentation, the

Applications of Landscape Genetics to Study the Effect of Varying Landscapes and Environmental Challenges in Plant Populations

Landscape genetics has recently evolved as a discipline, through which, it can incorporate the effect of local habitats and connectivity of the landscapes to analysis of gene flow and allows a better understanding of local adaptation processes by helping to develop novel hypothesis on impending selection forces.

Landscape Genetics: From Classic Molecular Markers to Genomics

This chapter outlines basic concepts in landscape genetics, the main statistical methods used so far, and the perspectives of this field of knowledge into strategies for conservation of natural populations of plant and animal species.

Genetic analysis of landscape connectivity in tree populations

This work describes how one can study gene movement of both pollen and seeds in the context of changing landscapes and describes methods for contemporary seed movement, and describes findings about gene flow and genetic diversity resulting from seed movement.

Testing concordance and conflict in spatial replication of landscape genetics inferences

The field of landscape genetics relates habitat features and genetic information to infer dispersal and genetic connectivity between populations or individuals distributed across a landscape. Such

Adaptive vs. neutral genetic diversity: implications for landscape genetics

Genetic diversity is important for the maintenance of the viability and the evolutionary or adaptive potential of populations and species. However, there are two principal types of genetic diversity:

Non-random distribution of individual genetic diversity along an environmental gradient

This study assessed the effects of habitat quality on population structure and individual genetic Diversity of tree swallows breeding along a gradient of agricultural intensification in southern Québec, Canada and found that individual genetic diversity was greater in poorer quality habitats.

Putting the ‘landscape’ in landscape genetics

A definition for the term ‘landscape genetics’ is offered, an overview of the landscape genetics literature is provided, guidelines for appropriate sampling design and useful analysis techniques are given, and future directions in the field are discussed.

Adaptive Genetic Variation on the Landscape: Methods and Cases

A review of the design of landscape genetics studies, the different statistical tools, some important case studies, and perspectives on how future advances in this field are likely to shed light on important processes in evolution and ecology are provided.

A useful strategy may be to identify areas that are important to represent species and genetic diversity and maximize within these areas the protection of contiguous environmental gradients across which selection and migration can interact to maintain population viability and adaptive genetic diversity.

LANDSCAPE STRUCTURE AND HIERARCHICAL GENETIC DIVERSITY IN THE BROOK CHARR, SALVELINUS FONTINALIS

Evidence is provided for the role of contemporary landscape features in shaping the observed pattern of genetic diversity at smaller geographic scales (within and among populations within river drainage) and for the increasing evidence for nonequilibrium conditions between drift and migration in a wide array of animal taxa.

It is concluded that natural selection, possibly interacting with founder events, has influenced the population differentiation of these three long-lived plant species.

The term "population genomics" is introduced to describe the process of simultaneous sampling of numerous variable loci within a genome and the inference of locus-specific effects from the sample distributions.

It is proposed that the intercept of a spatial correlogram can be an indication of the minimum distance between samples that can conserve and assess genetic diversity with maximum efficiency at lower costs.

Using eight hypervariable microsatellite loci to study the genetic relationships between four Canadian polar bear populations indicates that gene flow between local populations is restricted despite the long‐distance seasonal movements undertaken by polar bears.

A very general multivariate method, based on genetic distance methods, is developed that is applicable to multiallelic codominant, multilocus arrays and illustrated with an example data set from the orchid Caladenia tentaculata.

Canonical correspondence analysis for estimating spatial and environmental effects on microsatellite gene diversity in brook charr (Salvelinus fontinalis)
