Location Mexico. Methods We performed a literature and data survey of the climatic, geological and phylogeographical history of the Mexican highlands. We then assessed how the expected effects of topographic isolation, co-occurring palaeoclimatic fluctuations and volcanism can be tested against the distribution of genetic diversity of high-elevation taxa. Results The Mexican highlands present a complex biogeographical, climatic and geological history. Montane taxa have been exposed to a sky-island dynamic through climate fluctuations, allowing for long-term in situ population persistence, while also promoting recent divergence and speciation events. Volcanic activity transformed part of the Mexican highlands during the Pleistocene, mainly in the TMVB, leading to co-occurring climate and topographical changes. The TMVB highlands provide a suitable template to examine how low-latitude mountains can facilitate both the long-term persistence of biodiversity as well as allopatric and parapatric speciation driven by climatic and geological events. Main conclusions Climate fluctuations, together with recent volcanism, have driven the diversification and local persistence of biodiversity within the Mexican highlands. The climate–volcanism interaction is challenging to study; however, this can be overcome by coupling genomic data with landscape analyses that integrate the geological and climatic history of the region. 10aGenetic diversity10aglacial periods10aMexican trout10aNeogene10aphylogeography10aPleistocene10atropical mountains10avolcanism1 aMastretta-Yanes, Alicia1 aMoreno-Letelier, Alejandra1 aPiñero, Daniel1 aJorgensen, Tove, H.1 aEmerson, Brent, C. uhttp://onlinelibrary.wiley.com/doi/10.1111/jbi.12546/abstract02597nas a2200277 4500008004100000022001400041245013500055210006900190300001600259490000700275520170100282653002201983653002002005653001802025653001202043653001902055653001602074653002302090653001402113100002802127700003102155700002002186700002402206700002302230856006602253 2015 eng d a1365-269900aBiodiversity in the Mexican highlands and the interaction of geology, geography and climate within the Trans-Mexican Volcanic Belt0 aBiodiversity in the Mexican highlands and the interaction of geo a1586–16000 v423 aAim (1) To synthesize data on the physical and phylogeographical history of the Mexican highlands, with a focus on the Trans-Mexican Volcanic Belt (TMVB), and (2) to propose approaches and analyses needed for examining the interaction of climate and volcanism.

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.10aCDMetaPOP10aexotic trout10aMexican trout10aOncorhynchus chrysogaster10arainbow trout10ariverscape genetics10aspecies distribution modelling10aTruchas Mexicanas1 aEscalante, Marco, Alejandro1 aDe León, Francisco, J.

Se reconoce la existencia de la especie Oncorhynchus chrysogaster (Needham y Gard, 1964), denominada Trucha dorada mexicana (PISCES: Salmonidae), misma que está reportada como especie endémica amenazada en la NOM-059-SEMARNAT-2010 y como especie vulnerable en CITES (Conference on International Trade in Endangered Species). La situación de riesgo es aún más grave si se considera que estudios recientes indican que por la heterogeneidad genética de este complejo de peces, es posible la identificación de nuevas especies o subespecies de truchas nativas (Hendrickson et al., 2002, Hendrickson et al., 2006). Considerando lo anterior y tomando en cuenta que existen algunas iniciativas (particularmente realizadas por académicos estadounidenses y mexicanos), enfocadas al estudio sistemático y genético de este grupo de peces, se propone complementarlas con el análisis espacial del paisaje del área de distribución potencial de O. chrysogaster. Para ello se analizarán los registros históricos, los datos existentes con referencia geográfica específica y adicionalmente los datos que se generen a partir de este proyecto, para producir un modelo de distribución de esta especie en la Sierra Madre Occidental. Dado el escaso registro con que se cuenta se considera indispensable la colecta con fines de ampliar dicho registro, pero particularmente con la intención de validar en lo posible el modelo que se genere. Se aplicarán técnicas de percepción remota que permitirán identificar las características ambientales de las localidades de registro (red hidráulica, altitud, pendiente, tipos de cobertura) y que podrán ser incorporadas a un sistema de información geográfica (SIG), conjuntamente con información auxiliar (temperaturas promedio, precipitación, geología, etc.). La identificación de estas características, en conjunto con datos de la presencia/ausencia de las truchas permitirá generar mapas de susceptibilidad de las áreas de distribución de estas especies por medio de modelos del nicho ecológico, por ejemplo MAXENT y Mahalanobis.10aMexican trout10aOncorhynchus chrysogaster1 aLuna, Arturo, Ruiz uhttps://www.gbif.org/dataset/90711430-4260-422f-aeb2-26ce7f72f56c01503nam a2200181 4500008004100000020002200041245005700063210005500120250000600175260006100181520090700242653001401149653001201163653001801175100002201193700003601215856007001251 2016 eng d a978-607-7900-26-900aLa Trucha Dorada Mexicana / The Mexican Golden Trout0 aLa Trucha Dorada Mexicana The Mexican Golden Trout a1 aMéxicobArturo Ruiz Luna and Francisco García de León3 aLa trucha dorada mexicana (Oncorhynchus chrysogaster) es un pez endémico de México que habita en aguas frías de alta montaña en la Sierra Madre Occidental.

The Mexican native trout complex is the group of salmonids that naturally has the southernmost distribution in the world. Despite its unique status and evidence of more than 13 distinct lineages, there are only two described species (Oncorhynchus mykiss nelsoni and O. chrysogaster). These fishes are threatened by environmental and anthropogenic factors, most notably the introduction of the exotic species O. mykiss (rainbow trout) for aquaculture. Here we applied population genetics analysis in 1,017 wild and cultured trout to understand the extent of genetic introgression of rainbow trout in Mexican native trout. Present results indicate a high degree of introgression and genetic admixture among introduced rainbow trout and some populations of Mexican native trout, exposing them to loss of genetic diversity. Thus, introduction of exotic trout for aquaculture purposes must be strictly regulated or avoided and we advise the use of native trout for aquaculture.

Upon visiting the remote, largely un­developed watershed during two hunting trips in the 1930s, renowned conservationist Aldo Leopold thought it was the best picture of land health he had seen. His main indicators of healthy land were slow water runoff rates regulating erosion and historical predator-prey relationships. The visits confirmed Leopold's concept of land health, inspired many of his essays, and helped shape his land ethic. Leopold proposed the area as a control site to research healthy land throughout North America . The proposal never went forward and the area has since been more intensively logged and grazed. This dissertation research used extensive literature review, archives, oral histories, citizen surveys, and rapid assessment of forest, rangeland, riparian, and socioeconomic health to assess impacts of past cultures and update the area's land health status. Projects that could restore land health, such as linked eco-tourism, forest density reduction, and rotational grazing, were assessed for feasibility. Recent critiques of Leopold's land ethic were also reviewed. Results indicate most pre-1940s impacts were light, current land health status is moderate, and local interest exists in restoring land health. Many fish and wildlife populations are reduced, temporarily stabilized, but still at risk. Soil and riverbed erosion, service sector economics, and (at some ridge-top sites) forest density are the land health indicators in worst condition. Land health restoration projects are feasible.10aChihuahua10aMexican trout10aRio Yaqui10atrout1 aForbes, William uhttps://truchasmexicanas.myspecies.info/content/revisiting-aldo-leopolds-perfect-land-health-conservation-and-development-mexicos-rio00604nas a2200205 4500008004100000245008900041210006900130260001600199300001200215490000700227653001400234653001800248653001400266653001300280653002800293653001000321100002100331700002000352856002600372 2006 eng d00aFollowing in Leopold's Footsteps: Revisiting and Restoring the Rio Gavilan Watershed0 aFollowing in Leopolds Footsteps Revisiting and Restoring the Rio c2006/01/01/ a25 - 310 v2410aChihuahua10aMexican trout10aRio Yaqui10ariparian10aSierra Madre Occidental10aYaqui1 aFleming, William1 aForbes, William uhttp://er.uwpress.org00572nam a2200157 4500008004100000020002200041245003700063210003700100260009300137300000800230653001800238100002300256700001900279700002300298856009300321 2009 eng d a978-607-7607-20-500aPeces Dulceacuícolas de México0 aPeces Dulceacuícolas de México aMexico, D.F.bComisión Nacional para el Conocimiento y Uso de la Biodiversidadc2009/// a55910aMexican trout1 aMiller, Robert, R.1 aMinckley, W.L.1 aNorris, Steven, M. uhttps://truchasmexicanas.myspecies.info/content/peces-dulceacu%C3%ADcolas-de-m%C3%A9xico02166nam a2200181 4500008004100000020001800041245003800059210003800097260003600135300000800171520160000179653001801779653002801797653002301825653003401848100001901882856008301901 2010 eng d a978145160355200aTrout and Salmon of North America0 aTrout and Salmon of North America bSimon and Schusterc2010/07/06/ a3763 aThis beautiful and definitive guide brings together the world's lead leading expert on North American trout and salmon, Robert Behnke, and the foremost illustrator in the field, Joseph Tomelleri.North America is graced with the greatest diversity of trout and salmon on earth. From tiny brook trout in mountain streams of the Northeast, to cutthroat trout in the rivers of the Rockies, to Chinook salmon of the Pacific, the continent is home to more than 70 types of trout and salmon.

A pesar de que Baja California Sur (BCS) es tipificada como una regiónárida y con pocas corrientes epicontinentales en sus vertientes Pacífico y Golfo de California (Tamayo, 1962), existen numerosos cuerpos de agua perennes conocidos como “oasis” que representan eocosistemas mesófilos relictos de afinidad subtropical (Axelrod, 1948, 1979; Grismer y McGuire, 1993). Estos oasis son habitados por peces con diferentes historias biogeográficas y evolutivas, siendo escenarios de endemismos autóctonos (Fundulus lima y Gobiesox juniperoserrai) o de colonización vía fluvial por especies eurihalinas de estirpe marina (Follett, 1960; Espinosa Pérez y Castro-Aguirre, 1996; Ruiz-Campos et al., 2003). En términos ecogeográficos, no hay peces dulceacuícolas de origen primario o secundario en BCS (Follett, 1960) y varios factores causales han sido propuestos para explicar tal situación: (1) discontinuidad paleohidrológica entre los arroyos del sur de California y de la península de Baja California durante la disminución del nivel del mar en el Pleistoceno tardío; (2) la prolongada aridez prevaleciente desde el inicio del Holoceno ha frenado la dispersión de peces por vía estuarina a través de la costa peninsular; (3) lo abrupto de gran parte de la costa oriental ha evitado la formación de lagunas y complicado la dispersión; y (4) el Golfo de California actúa como una barrera para la entrada de peces dulceacuícolas desde Mesoamérica. ● Peces dulceacuícolas de Baja California Sur Follett (1960) reportó 21 especies dulceacuícolas nativas para BCS, sin ningún caso de introducción de especies exóticas. Posteriormente, Ruiz-Campos y Contreras-Balderas (1987) incrementaron este número a 28, aportando primeros registros de tres especies periféricas esporádicas (Harengula thrissina, Hypsopsetta guttulata y Achirus mazatlanus) y tres exóticas (Gambusia affinis, Poecilia reticulata y Xiphophorus maculatus). Muchos de los registros referidos por ambos estudios fueron procedentes de las partes bajas de los ríos Muelegé y San José del Cabo, pero sin evidencia

A broad-scale survey of potential trout habitats in upper tributaries of the Río Conchos of Chihuahua, México resulted in the re-discovery in 2005 of a long-lost native, endemic, and now endangered, undescribed trout species that we call the "Conchos Trout." We are currently in the process of scientifically describing this rare trout, the only native Mexican trout known from an Atlantic drainage. Our extensive field efforts to date clearly indicate that this species was formerly much more widely distributed historically. Though surveys should continue, our extensive field surveys found only one small isolated and extremely vulnerable population, leaving us less than optimistic that many other, if any, additional populations will be found. Persistence of this new critically endangered endemic Conchos Trout clearly requires rapid conservation action. Our consensus expert opinion is that we cannot over-emphasize the urgency of protection for this critically endangered population of this unique trout, and so we have produced this "white paper" in hopes that it might encourage others to join us in initiating appropriate conservation programs. The potentially viable population is restricted to a short reach of a very small stream where it and another newly discovered, undescribed fish species, a sucker (and likely another unique taxon), could be relatively easily protected, studied and managed. Additionally, adjoining arroyos where the species recently occurred offer the possibility of restoring native fish populations to them following appropriate protection and habitat restoration efforts. All members of our highly qualified and diversely specialized, binational "Truchas Mexicanas" team stand prepared to join collaborators and invest personal resources in hands-on actions to help this new species persist. We recommend immediate establishment of a small reserve centered around currently occupied habitat and adjacent streams having suitable habitat, combined with education and compensation of local residents for their cooperation with reserve management. We recognize that we are largely ignorant of the local political and cultural systems via which conservation actions will have to proceed and are limited with regard to our ability to raise funds. We thus hope that readers of this white paper will add their financial and in-kind support and additional expertise to help us conserve the Conchos Trout!

The variation and composition of Mexican wild trout mitochondrial DNA haplotypes throughout northwestern Mexico was determined by means of polymerase chain reaction-restriction fragment polymorphism analysis (PCR-RFLP), of one region of mitochondrial DNA between cytochrome b and the D-loop. This analysis was based on 261 specimens taken in 12 basins and four hatcheries from northwestern Mexico. From 23 haplotypes, 15 wild trout haplotypes were identified and classified in four groups: (1) one restricted to Nelson's trout (Oncorhynchus mykiss nelsoni), (2) four restricted to R¡o Mayo and R¡oYaqui trout (O. mykiss sspp.), (3) six to Mexican golden trout (O. chrysogaster) with two subgroups, and (4) one exclusive to R¡o Piaxtla trout. Distributions of native haplotypes broadly overlap the distribution of non-native hatchery rainbow trout reflecting the historical management of introductions of exotic rainbow trout and the artificial transference of these trout among basins.

We present seventeen microsatellite loci developed for the Mexican golden trout Oncorhynchus chrysogaster through GS-FLX 454 pyrosequencing. We selected 34 primer pairs tested on 19 trout specimens from The Rio Verde (Rio Fuerte Bain) and we tested cross amplification on 35 trout specimens collected in seven hydrological basins from the Sierra Madre Occidental and Sierra San Pedro Mártir, as well as five hatchery reared Oncorhynchus mykiss. We observed medium and high genetic variation among loci (mean number of alleles per locus = 8.0, SD = 2.92; mean H O = 0.65, SD = 0.27). These loci are the first to be characterized explicitly for O. chrysogaster and they are expected to be useful for population studies in this species and as reference for species delimitation.

The Northwestern Sierra Madre Occidental of Mexico is a rugged mountain range covering portions of Sonora, Chihuahua, Durango and Sinaloa, and is drained by multiple Pacific Slope Rivers to the west and the Casas Grandes, Conchos, and Nazas to the east. The overall area is topographically, climatically and biotically diverse, ranging from endorheic basins (Casas Grandes) to mountainous areas elevations up to 3348 m, average mean temperatures from 10-20°C and precipitation from 250- 1100 mm/yr. The region is also geological complex that, combined with these other variables, provides a great diversity of both aquatic and terrestrial habitats conducive to both biotic endemicity and diversity. The overall diversity of the region has contribiited to the recent listing of this region by Conservation International as one of six new high-priority biodiversity hotspots. Our understanding of the aquatic and terrestrial biodiversity of this region, however, is poor and in urgent need of rapid investigation by collaborative communities. The combination of an incredibly rugged landscape, drug and bandit activities and indigenous peoples that have not always been welcoming to visitors has resulted in a general paucity of roads in the region, and the lack of access has limited inventory studies. Recently, however, access to the region has changed dramatically and many of the areas are now accessible enough for logging, mining, and agriculture practices, all exerting extreme pressures in some areas on the biodiversity. In addition to human-induced changes to these diverse ecosystems, impacts of invasive aquatic species are becoming more and more apparent, and the potential for severely reducing population sizes of species or their extirpation or extinction is real. While several invasive or exotic species are identified as potentially destructive to these communities, the exotic Rainbow Trout (Oncorhynchus mykiss) that is derived from hatcheries or culture facilities within the region represents one of the most critical threats to the aquatic and semi-aquatic biodiversity. The native trout of mainland Mexico represent the southern- most salmonids, and are at imminent risk of introgression and/or replacement by feral Rainbow Trout, Oncorhynchus mykiss. Our recent survey efforts have expanded the known diversity and ranges of each of several distinct forms, which we feel represent valid species. We discuss our discovery of multiple new species from the Sierra Madre Occidental and focus on a new species of trout restricted to the upper Conchos drainage, the first native species of Oncorhynchus known to occupy the Atlantic Slope in Mexico. Many of these taxa are restricted to small areas of intact habitat in headwater areas of high-elevation streams, and are at risk from a suite of human-associated perturbations, emerging diseases, and introduced species. These fishes occupy unique habitats, and represent a diverse portion of the Mexican montane ichthyofauna. The habitats on which they depend support a wide range of other aquatic organisms, most of which are grossly understudied. The discovery of the Conchos Trout derived primarily by GARP niche modeling of a subset of localities of previously sampled undescribed native Mexican trout, provides only a snapshot of the biodiversity awaiting to be discovered in this region. The rugged landscape of the Sierra Madre Occidental simply precludes routine sampling at easily accesible locations of streams and most sampling locations require time-intensive access. In an effort to rapidly assess the biodiversity of rivers of this region we employed this method to aid in predicting the most suitable and highly probable Mexican trout niches in the region. This method offered highly efficient and powerful results that not only predicted the occurrence of a previously unknown trout in the upper Rio Conchos but also provided excellent predictions of available habitats in drainages where previously unknown trout have been discovered by the Truchas Mexicanas team in the last nine years. Multiple threats exist to the biodiversity of the northern Sierra Madre Occidental, including uncontrolled introductions of exotic and invasive species, emerging diseases such as whirling disease, Myxobolus cerebralis, infectious pancreatic necrosis (IPN), iridioviruses and pathogenic water mold, Saprolegnia ferax, land-use practices leading to habitat degradation via overgrazing, logging, deforestation and road construction, increasing human population growth, over-fishing or overharvesting of aquatic resources and global climate cliange reducing surface and ground water in the area and creating environments more conducive to the spread of invasive species, congregated and dense human populations, and emerging diseases. Immediate actions need to be developed to aid in public education as to the threats to these ecosystems, protection of areas, assessment of diversity, and sustainable development throughout the region that incorporates a likely highly successful ecotourism system for the region.

Historic records provide evidence that Rio Grande cutthroat trout(Oncorhynchus clarki virginalis) were indigenous to some Texas streams. This information includes railroad survey reports and several accounts in a major sporting publication of the late 1800s, including a drawing with color description. Published accounts continued through the mid-1900s, after which man's activities made these streams unsuitable for trout survival.

In August 1952, a beautiful, golden-coloredtrout was collected in the Rio Verde near Guadalupe y Calvo in southwestern Chihuahua. This trout was described, but not named, by Needham and Gard (1959). We did not name it at that time because we had little information concerning the amount of variability found in western North American members of the genus Salmo throughout its entire range. Before this trout was named we wanted to be confident that its distinctive characters had a genetic basis and were not mainly phenotypic expressions of local environmental phenomena. The compilation of data by Needham and Behnke (unpublished) on more than 2,000 specimens of the genus Salmo from western North America, collected from virtually their entire native range, has demonstrated that, indeed, the Mexican golden trout is a distinct group and worthy of taxonomic recognition. Taxonomic methods used are essentially those listed in Hubbs and Lagler (1949) with the modifications noted in Needham and Gard (1959).
