“…This mountain system is one of the 14 biogeographic provinces of Mexico and one of the five biogeographic provinces of the so-called Mexican Transition Zone, mainly defined by the plant and animal taxa that are found above 1000 m. This province has the highest Nearctic influence [11]. …”

BackgroundStudies of the phylogeography of Mexican species are steadily revealing genetic patterns shared by different species, which will help to unravel the complex biogeographic history of the region. Campostoma ornatum is a freshwater fish endemic to montane and semiarid regions in northwest Mexico and southern Arizona. Its wide range of distribution and the previously observed morphological differentiation between populations in different watersheds make this species a useful model to investigate the biogeographic role of the Sierra Madre Occidental and to disentangle the actions of Pliocene tecto-volcanic processes vs Quaternary climatic change. Our phylogeographic study was based on DNA sequences from one mitochondrial gene (cytb, 1110 bp, n = 285) and two nuclear gene regions (S7 and RAG1, 1822 bp in total, n = 56 and 43, respectively) obtained from 18 to 29 localities, in addition to a morphological survey covering the entire distribution area. Such a dataset allowed us to assess whether any of the populations/lineages sampled deserve to be categorised as an evolutionarily significant unit.ResultsWe found two morphologically and genetically well-differentiated groups within C. ornatum. One is located in the northern river drainages (Yaqui, Mayo, Fuerte, Sonora, Casas Grandes, Santa Clara and Conchos) and another one is found in the southern drainages (Nazas, Aguanaval and Piaxtla). The split between these two lineages took place about 3.9 Mya (CI = 2.1-5.9). Within the northern lineage, there was strong and significant inter-basin genetic differentiation and also several secondary dispersal episodes whit gene homogenization between drainages. Interestingly, three divergent mitochondrial lineages were found in sympatry in two northern localities from the Yaqui river basin.ConclusionsOur results indicate that there was isolation between the northern and southern phylogroups since the Pliocene, which was related to the formation of the ancient Nazas River paleosystem, where the southern group originated. Within groups, a complex reticulate biogeographic history for C. ornatum populations emerges, following the taxon pulse theory and mainly related with Pliocene tecto-volcanic processes. In the northern group, several events of vicariance promoted by river or drainage isolation episodes were found, but within both groups, the phylogeographic patterns suggest the occurrence of several events of river capture and fauna interchange. The Yaqui River supports the most diverse populations of C. ornatum, with several events of dispersal and isolation within the basin. Based on our genetic results, we defined three ESUs within C. ornatum as a first attempt to promote the conservation of the evolutionary processes determining the genetic diversity of this species. They will likely be revealed as a valuable tool for freshwater conservation policies in northwest Mexico, where many environmental problems concerning the use of water have rapidly arisen in recent decades.

“…The second group belongs to the Mexican transition zone (Morrone, 2010(Morrone, , 2015a. Two generalized tracks run parallel to the Sierra Madre Occidental province (D and E), 2 across the Chihuahuan Desert and the Sierra Madre Oriental provinces (F and G), one runs parallel to the Transmexican Volcanic Belt province (H), and another runs parallel to the Sierra Madre del Sur province (I) (Fig.…”

“…Track analysis is aimed to identify biotas, which are sets of spatiotemporally integrated taxa that characterize biogeographic areas and are the basic units of evolutionary biogeography (Morrone, 2004(Morrone, , 2010. By searching for repetitive distributional patterns, track analysis identifies biogeographically homologous distributions, allowing the correlation of distributional pattern of unrelated taxa and leading to the recognition of ancestral biotas (Morrone & Márquez, 2001).…”

We analyzed distributional data of 59 species of funnel-web spiders (Araneae: Agelenidae) of Mexico. We constructed individual tracks for the species analyzed, based on published and unpublished records, and based on their overlap we obtained 9 generalized tracks. Three generalized tracks belong to the Californian Nearctic dominion (Nearctic region) and 6 generalized tracks extend along the Mexican transition zone. Seven generalized tracks are defined by species of the same genus or closely related genera and 2 generalized tracks are supported by species of distantly related genera, which shows that both spatial relationships and phylogenetic evidence support the existence of ancestral biotas including unrelated taxa.Keywords: Biogeography; Mexican transition zone; Ageleninae ResumenSe analizaron los datos de distribución de 59 especies de arañas tejedoras de red de embudo (Araneae: Agelenidae) de México. Construimos los trazos individuales de las especies analizadas utilizando registros publicados y sin publicar y, con base en su superposición, obtuvimos 9 trazos generalizados. Tres trazos generalizados pertenecen al dominio Neártico Californiano (región Neártica) y 6 trazos generalizados se extienden a lo largo de la Zona de Transición Mexicana. Por otro lado, 7 trazos generalizados están definidos por especies del mismo género o géneros relacionados cercanamente y 2 trazos generalizados están apoyados por especies de géneros relacionados lejanamente, lo cual muestra que las relaciones espaciales y la evidencia filogenética sustentan la existencia de biotas ancestrales conteniendo taxones no relacionados.Palabras clave: Biogeografía; Zona de Transición Mexicana; Ageleninae J.

“…These findings are consistent with the Mexican Transition Zone as defined by Halffter [36], [37] an area in which Neotropical and Nearctic biotic components overlap. This zone includes South-western USA, Mexico and a large part of Central America and has been extensively studied previously [38], [39], [40], [41].…”

In this paper, we analyse the distributional patterns of adult helminth parasites of freshwater fishes with respect to the main hydrological basins of Mexico. We use the taxonomic distinctness and the variation in taxonomic distinctness to explore patterns of parasite diversity and how these patterns change between zoogeographical regions. We address questions about the factors that determine the variation of observed diversity of helminths between basins. We also investigate patterns of richness, taxonomic distinctness and distance decay of similarity amongst basins. Our analyses suggest that the evolution of the fauna of helminth parasites in Mexico is mostly dominated by independent host colonization events and that intra - host speciation could be a minor factor explaining the origin of this diversity. This paper points out a clear separation between the helminth faunas of northern - nearctic and southern - neotropical components in Mexican continental waters, suggesting the availability of two distinct taxonomic pools of parasites in Mexican drainage basins. Data identifies Mexican drainage basins as unities inhabited by freshwater fishes, hosting a mixture of neotropical and nearctic species, in addition, data confirms neotropical and neartic basins/helminth faunas. The neotropical basins of Mexico are host to a richest and more diversified helminth fauna, including more families, genera and species, compared to the less rich and less diverse helminth fauna in the nearctic basins. The present analysis confirms distance - decay as one of the important factors contributing to the patterns of diversity observed. The hypothesis that helminth diversity could be explained by the ichthyological diversity of the basin received no support from present analysis.
