Using a comparative approach to investigate the relationship between landscape and genetic connectivity among woodland salamander populations

Landscape genetics reveals contrasting patterns of connectivity in two newt species (Lissotriton montandoni and L. vulgaris)

“…However, only studies comparing the same or closely related species can account for biases associated with the use of various molecular markers and/or resulting from contingencies of evolutionary history. Furthermore, variation among different parts of a species range is also common (e.g., Burgess & Garrick, 2020; Cameron et al, 2019; Robertson et al, 2018). Our ability to distinguish general patterns from regional idiosyncrasies, which are known to be strongly driven by biological (e.g., population dynamics; Dudaniec et al, 2012) and spatial factors (e.g., landscape configuration; Burgess & Garrick, 2020) depends on study designs that involve replicated regions.…”

Fine-scale habitat suitability and connectivity analysis for the core populations of Yellow-spotted mountain pond-breeding newt (Neurergus derjugini) in the west of Iran and east of Iraq

“…The highest current intensity occurs from the population core 9 to 12. In Basin 3, the highest current intensity is in the path of population cores 11,12,15,19,20,21,24,26, and 32 to 35. The characteristics of the three quality corridors in each basin based on the EWD: ED and CWD: LCP metrics are shown in Table 1.…”

“…Therefore, it would be of utmost importance to keep the connection between aquatic and terrestrial habitats (Becker et al, 2007). Reducing genetic diversity in a fragmented landscape (Pittman et al, 2014) reduces genetic connections, perpetuates population threats, and reduces the adaptive potential of species (Cameron et al, 2019). Amphibians are characterized by two common characteristics of inactivity and loyalty to the site of birth (Duellman and Trueb, 1994); thus, these species are generally believed to have little mobility and are often metapopulations (Marsh and Trenham, 2001).…”

Landscape Genetics of Plants: Challenges and Opportunities

“…The field of landscape genetics (genomics) was developed to test specific hypotheses about the influences of landscape features on the patterns of effective dispersal. Landscape genetics has most often been used to evaluate the movement patterns of animals ( Storfer et al., 2010 ; Rissler, 2016 ; Beninde et al., 2018 ; Dileo et al., 2018 ; Cameron et al., 2019 ; Kunde et al., 2019 ; Lourenco et al., 2019 ; Yadav et al., 2019 ), but more studies on plants are beginning to emerge (e.g., Vandepitte et al., 2007 ; Arredondo et al., 2018 ; Morente-López et al., 2018 ; Alvarado-Serrano et al., 2019 ; Grasty et al., 2020 ).…”
