Despite some efforts from science groups to obtain information about this trout, the Rio Sinaloa and Rio Culiacan basins, to the south, remain the least studied area, compared to the Rio Fuerte basin. To overcome this gap, a survey (2014 to 2015) was undertaken to obtain new records and confirm the presence for historic records in both watersheds. After filtering records for this species, eighteen locations were used to model potential distribution, using the GARP and MaxEnt, including landscape characterization based on hydrologic analysis and satellite imagery classification. Coincidence between models was >85% for a potential distribution area of 4300 km2, defined by six bioclimatic and physiographic variables, with the hydrologic network covering 3000 km. To avoid overestimation, the final distribution area included only the 100 m fringe surrounding the drainage network and its associated landscape features. Jackknife resampling was used to validate both the models, successfully predicting more than 80% of the locations (p < 0.001). The estimated area covers 275 km2, mainly defined by second- and third-order streams, at altitudes >2000 m, high water quality (transparent, dissolved oxygen >5 mg L-1; temperature < 26 °C), and was part of a matrix of undisturbed forests. This study provides new findings about this endangered species and new elements for designing appropriate monitoring programs supporting trout conservation and management.1 aRuiz-Luna, Arturo1 aHernández-Guzmán, Rafael1 aDe León, Francisco, J.

The seasonal thermal interval and daily duration of summer temperatures above the thermal threshold for this trout subspecies (≥ 28°C) were determined in streams at different elevations (553, 1,220, and 2,080 masl, or meters above sea level). Temperatures ≥ 28°C were recorded at the study site on the stream with the lowest elevation (San Antonio de Murillos Creek) over an accumulated 365 h between June and September 2014, with the maximum temperature recorded there, 30.66 °C, making it the site most vulnerable to climate change. At the San Antonio de Murillos Creek, the average water temperature predicted by three models (GFDL R30, HadCM3, and Mote) for the year 2025 would be a non-lethal temperature, < 28 °C, for trout at a minimum elevation of 491-511 masl, while this was predicted to be 545-701 masl for the year 2050. Predicted hourly water temperatures of 28°C (non-lethal) may occur at minimum elevations of 868-898 masl in 2025 and at 908-1028 masl in 2050, reducing a 21-23% and 23-31% its current altitudinal distribution range, respectively, thus avoiding its presence at the type locality (San Antonio de Murillos).10aclimate change10acreek10aendemic10amodel10aOncorhynchus mykiss nelsoni10awater temperature1 aMeza-Matty, Iván, Alejandro1 aRuiz-Campos, Gorgonio1 aDaesslé, Luis, Walter1 aRuiz-Luna, Arturo1 aLópez-Lambraño, Álvaro, Alberto1 aCamarena-Rosales, Faustino1 aMatthews, Kathleen, R.  uhttps://www.jlimnol.it/index.php/jlimnol/article/view/jlimnol.2021.200102599nas a2200181   4500008004100000020001400041245021700055210006900272260001200341520189700353100002502250700002102275700003602296700002202332700002702354700002202381856001402403       2020                        eng d  a1566-062100aGenotyping-by-sequencing reveals the effects of riverscape, climate and interspecific introgression on the genetic diversity and local adaptation of the endangered Mexican golden trout (Oncorhynchus chrysogaster)0 aGenotypingbysequencing reveals the effects of riverscape climate  c2020///3 aHow environmental and anthropogenic factors influence genetic variation and local adaptation is a central issue in evolutionary biology. The Mexican golden trout (Oncorhynchus chrysogaster), one of the southernmost native salmonid species in the world, is susceptible to climate change, habitat perturbations and the competition and hybridization with exotic rainbow trout (O. mykiss). The present study aimed for the first time to use genotyping-by-sequencing to explore the effect of genetic hybridization with O. mykiss and of riverscape and climatic variables on the genetic variation among O. chrysogaster populations. Genotyping-by-sequencing (GBS) was applied to generate 9767 single nucleotide polymorphisms (SNPs), genotyping 272 O. chrysogaster and O. mykiss. Population genomics analyses were combined with landscape ecology approaches into a riverine context (riverscape genetics). The clustering analyses detected seven different genetic groups (six for O. chrysogater and one for aquaculture O. mykiss) and a small amount of admixture between aquaculture and native trout with only two native genetic clusters showing exotic introgression. Latitude and precipitation of the driest month had a significant negative effect on genetic diversity and evidence of isolation by river resistance was detected, suggesting that the landscape heterogeneity was preventing trout dispersal, both for native and exotic individuals. Moreover, several outlier SNPs were identified as potentially implicated in local adaptation to local hydroclimatic variables. Overall, this study suggests that O. chrysogater may require conservation planning given (i) exotic introgression from O. mykiss locally threatening O. chrysogater genetic integrity, and (ii) putative local adaptation but low genetic diversity and hence probably reduced evolutionary potential especially in a climate change context.1 aEscalante, Marco, A.1 aPerrier, Charles1 aDe León, Francisco, J.
