	abstract = {How environmental and anthropogenic factors influence genetic variation and local adaptation is a central issue in evolutionary biology. The Mexican golden trout (            
            ), one of the southernmost native salmonid species in the world, is susceptible to climate change, habitat perturbations and the introduction of exotic rainbow trout (
            
            ) for aquaculture. The present study aimed to explore the effect of both genetic introgression from
            
            and riverscape variables on the genetic variation of
            
            . Genotyping-by-sequencing (GBS) was applied to generate 9 767 single nucleotide polymorphisms (SNPs), genotyping 270
            
            and aquaculture trout. Population genomics analyses were combined with riverscape genetics approaches. A small degree of admixture was identified between aquaculture and native trout, and significant effects of riverscape variables on genetic diversity were detected, as well as evidence of isolation by riverscape resistance within a basin. Gene-environment associations identified genes potentially implicated in adaptation to local hydroclimatic variables. This is an integrative study using a non-common multi-scale approach in landscape genetics for the conservation of an endangered riverine species.

	abstract = {Aim We explored the factors between riverscape features and exotic introgression of cultured rainbow trout (Oncorhynchus mykiss) that drive the current genetic structure in the endemic Mexican golden trout (Oncorhynchus chrysogaster) using a riverscape genetics simulator. Location Sierra Madre Occidental, Northwest Mexico, North America. Methods We created a system model for Mexican golden trout to test various scenarios for the effect of riverscape resistance and rainbow trout introgression on the native genetic structure of the Mexican golden trout. Individual genotypes were used to initialize the model and were based upon empirical allele frequencies from three genetically and spatially distinct groups in the study area. The geographical location of the simulated populations was defined using a species distribution model. We included hypotheses for movement of riverine distance and riverscape resistance. We evaluated model performance by conducting population and landscape genetics analyses on the simulation outputs. Results The most plausible scenario included riverscape resistance without introgression, which presented a spatial genetic structure matching the observed riverscape genetic structure and fitting expected general life-history patterns for high elevation trout streams. In addition, temperature, precipitation, hydrology and topography were the most important variables influencing species occurrence and dispersal. Main conclusion This work presents one of the first empirically derived simulation studies of introgression. It highlights the importance of considering riverscape resistance (i.e. hydroclimatic and topographical gradient effects) in models of spatial genetic structure and introgression. Moreover, our modelling suggests that what we characterize as riverscape resistance is acting as a boundary against exotic introgression. The results of this study could help to develop management strategies that preserve native gene pools.},
