poblacionales, hábitat y conservación de la trucha arcoíris costera, Oncorhynchus
mykiss nelsoni (Evermann), una subespecie endémica de los
arroyos de la pendiente occidental de la sierra San Pedro Mártir, en Baja
California, México.
Esta trucha, considerada en protección especial, representa la subespecie
más austral del complejo arcoíris en Norteamérica, cuyas poblaciones
enfrentan una serie de amenazas vinculadas con la alteración de hábitats
por impacto del ganado vacuno, la reducción de los fl ujos de los arroyos
por extracción y canalización para irrigación agrícola, y la reducción que,
eventualmente, tendrá su distribución altitudinal por el inminente efecto
del cambio climático global. Por ello, la conservación poblacional de esta
trucha dependerá de la planeación y aplicación oportuna de un programa
de conservación holística a nivel de cuencas hidrológicas que permita
garantizar la continuidad de este taxón endémico que es un patrimonio
biológico y un elemento insustituible de la historia natural de la sierra San
Pedro Mártir.

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.

Then, it is crucial to quantify potential extinction risks as consequence of global change related with human activities, especially in range restricted species. An example of that situation is represented by the native Mexican trout complex inhabiting the highlands of northwest Mexico and representing the group of salmonids with the southernmost distribution in the world, with the Mexican golden trout (Oncorhynchus chrysogaster) and the coastal nelson trout (O. mykiss nelsoni) as the only described species for this complex.However, as mountaintop species, these salmonids are highly vulnerable to global change effects, mainly by climate change and the introduction of the exotic rainbow trout for aquaculture purposes. The overall aim of this PhD project is to assess the possible relationships between microevolutionary processes of the Mexican golden trout, as well as the spatial structure of their habitat defining extinction risks derived by global change.To address those questions, a riverscape genetics approach was applied at different spatial scales and taxonomic levels including population genetics analyses based on neutral microsatellite markers and Next Generation Sequencing (NGS), G.I.S. (Geographic Information Systems; riverscape characterizations), species distribution modeling and demo-genetic simulations.Initially, population genetics analyses of 11 microsatellite loci revealed a spatial genetic structure for the entire Mexican trout complex as well as genetic introgression for native trout collected in aquaculture farm proximities, these results were corroborated by other using more microsatellite and SNPs markers. Moreover, focusing on O. chrysogaster, species distribution models and demogetic simulations defined riverscape as the main factor driving native population genetic structure, and as a boundary against exotic introgression. Additionally, 9,676 SNP’s were generated by NGS techniques defining a cryptic genetic structure for O. chrysogaster. Finally, landscape genomics approaches revealed a significant influence of riverscape factors on the neutral and adaptive genetic structure of the species.1 aSanchez, Marco, Alejandro  uhttps://tel.archives-ouvertes.fr/tel-01697876/document01699nas a2200349   4500008004100000245005800041210005700099260002600156300001400182490000600196520073500202653001900937653002300956653001700979653001200996653002201008653001101030653001901041653002401060653001101084653002301095653001001118653001301128100002101141700001801162700001401180700002401194700002101218700002801239700002701267856005501294       2017                        eng d00aCold-Water Fishes and Climate Change in North America0 aColdWater Fishes and Climate Change in North America  bElsevierc2017/11/29/  a103 - 1110 v23 aTrout, salmon, grayling and whitefishes (Salmonidae) are among the most ecologically and economically important fishes. They also are among the most vulnerable to global warming, and increasing drought, floods, and wildfires. In North America, salmonids occur from central Mexico northward along coastal regions and mountainous interiors to the Arctic Plains. A variety of existing stressors have reduced population sizes and extent and fragmented habitats, making salmonid populations increasingly vulnerable to climate-driven disturbances. This contribution explores specific threats posed by climate change and suggests actions that can help these coldwater-dependent species adapt to an increasingly warm and uncertain future.10aclimate change10aCumulative impacts10aDisturbances10aDrought10aFish conservation10aFloods10aGlobal warming10aOcean acidification10aSalmon10aStream restoration10atrout10aWildfire1 aWilliams, J., E.1 aIsaak, D., J.1 aImhof, J.1 aHendrickson, D., A.1 aMcMillan, J., R.1 aDellaSala, Dominick, A.1 aGoldstein, Michael, I.  uhttps://doi.org/10.1016/B978-0-12-809665-9.09505-7
