Species resilience to diversified environments largely depends on their genetic diversity. Disentangling the respective roles of multiple landscape factors population variation could help us interpret adaptive mechanism species environments, which is a central issue in evolutionary biology and biodiversity conservation. Herein, typical Tibetan loach Triplophysa stenura was selected as study object perform genetics analyses inferred from mitochondrial cytochrome b gene sequences. Based extensive sample collection, total 377 individuals 20 sites Yarlung Tsangpo River were included results diversity assessment demonstrated relatively high haplotype low nucleotide for most geographic populations. Genetic pattern analysis proved that both greater higher, colder drier areas, consistent with central-marginal hypothesis this plateau hinterland-originated species. Degree differentiation among populations varied level extremely level, coming mainly within Elevational climatic divergences detected be principally responsible formation structure species, coinciding isolation-by-environment model. On basis, we put forward some applicable proposals marginal elevations deserved more attentions designing conservation scheme those genetically differentiated should treated separate units. Under context global climate change intensifying human activity, sound resources monitoring along elevational or gradient pivotal develop future interventions.
