ارزیابی پیوستگی سیمای سرزمین و کریدورهای مهاجرتی آهوی گواتردار در مناطق مرکزی ایران
Long-term survival of Goitered gazelles in central Iran has been threatened because of isolation of existing populations and genetic threats. Effective management of these small and isolated populations needs to evaluate landscape connectivity among core habitat patches. In the present study, resistance surfaces were mapped as a function of twelve uncorrelated variables using species distributi...
متن کاملAssessment of Landscape Connectivity and Prediction of Migration Corridors for the Baluchistan Black Bear (Ursus thibetanus gedrosianus Blanford, 1877) in the Southeastern Habitats, Iran
The Baluchistan Black Bear (BBB), a critically endangered subspecies (CR), is distributed in the southeastern Iran. Modelling of landscape connectivity of the BBBs among habitat patches can be insightful for the conservation managers working in Iran. Our study was designed to identify the potential corridors among 31 habitat patches of the BBBs in Iran using the circuit theory method. Habitat s...
متن کاملGenetic differentiation and gene flow among populations of the alpine butterfly, Parnassius smintheus, vary with landscape connectivity.
Levels of gene flow among populations vary both inter- and intraspecifically, and understanding the ecological bases of variation in levels of gene flow represents an important link between the ecological and evolutionary dynamics of populations. The effects of habitat spatial structure on gene flow have received considerable attention; however, most studies have been conducted at a single spat...

متن کاملMicrosatellite Polymorphism Reveals Low Genetic Differentiation between Fall and Spring Migratory Forms of Endangered Caspian Trout, Salmo trutta caspius (Kessler, 1870)
The main objective of this study was to assess genetic comparison of two migratory forms of Caspian trout Salmo trutta caspius namely fall-run and spring-run. Owing to the lack of information on its genetic differences, 5 microsatellite loci were used for 58 sample analyses. Genomic DNA was extracted from caudal fin using Roche DNA extraction kit and each PCR reaction was performed in a 25 ?l ...
