Track analysis of the Mexican species of Cerambycidae (Insecta, Coleoptera)

Aim We analysed the geographical distributions of species of Buprestidae (Coleoptera) in Mexico by means of a panbiogeographical analysis, in order to identify their main distributional patterns and test the complex nature of the Mexican Transition Zone, located between the Nearctic and Neotropical regions. Location Mexico. Methods The geographical distributions of 228 species belonging to 33 genera of Buprestidae were analysed. Localities of the buprestid species were represented on maps and their individual tracks were drawn. Based on a comparison of the individual tracks, generalized tracks were detected and mapped. Nodes were identified as the areas where generalized tracks converged. Results Thirteen generalized tracks were obtained: one was restricted to the Mexican Transition Zone and five to the Neotropical region (Antillean and Mesoamerican dominions), a further two occurred in both the Nearctic region (Continental Nearctic dominion) and the Mexican Transition Zone, and a further five in both the Neotropical region (Mesoamerican dominion) and the Mexican Transition Zone. Seven nodes were identified at the intersections of the generalized tracks – in the Mesoamerican dominion (Mexican Pacific Coast, Mexican Gulf and Chiapas biogeographical provinces) and the Mexican Transition Zone (Trans‐Mexican Volcanic Belt, Balsas Basin and Sierra Madre Oriental biogeographical provinces). Main conclusions We conclude that the geographical distribution of Buprestidae is mainly Neotropical, corresponding to the Mesoamerican dominion and the Antillean dominion of the Neotropical region, and the Mexican Transition Zone. Most of the generalized tracks and nodes correspond to the Mexican Transition Zone, thus confirming its complex nature. We suggest that the nodes we have identified could be particularly important areas to choose for conservation prioritization.

They concluded that taxa isolated in the highlands of Chiapas (as well as Guatemala) at the end of the Pleistocene may represent the southernmost Nearctic relicts in Mesoamerica, and that the other biogeographic provinces, together with the Sierra Several other studies have contributed to the recognition of similar generalized tracks and nodes, and to the identification of smaller generalized tracks (Luna-Vega et al 1999, 2000, 2001, Morrone et al 1999, Morrone and Escalante 2002, Escalante et al 2003, Márquez and Morrone 2003, Ochoa et al 2003, Morrone and Gutiérrez 2005, Espinosa et al 2006, Contreras-Medina et al 2007a, Mariño-Pérez et al 2007, Toledo et al 2007, García-Marmolejo et al 2008). …”

Transition zones, located at the boundaries between biogeographic regions, represent events of biotic hybridization, promoted by historical and ecological changes. They deserve special attention, because they represent areas of intense biotic interaction. In its more general sense, the Mexican Transition Zone is a complex and varied area where Neotropical and Nearctic biotas overlap, from southwestern USA to Mexico and part of Central America, extending south to the Nicaraguan lowlands. In recent years, panbiogeographic analyses have led to restriction of the Mexican Transition Zone to the montane areas of Mexico and to recognize five smaller biotic components within it. A cladistic biogeographic analysis challenged the hypothesis that this transition zone is biogeographically divided along a north‐south axis at the Transmexican Volcanic Belt, as the two major clades found divided Mexico in an east‐west axis. This implies that early Tertiary geological events leading to the convergence of Neotropical and Nearctic elements may be younger (Miocene) than those that led to the east‐west pattern (Paleocene). The Mexican Transition Zone consists of five biogeographic provinces: Sierra Madre Occidental, Sierra Madre Oriental, Transmexican Volcanic Belt, Sierra Madre del Sur, and Chiapas. Within this transition zone, at least four cenocrons have been identified: Paleoamerican, Nearctic, Montane Mesoamerican, and Tropical Mesoamerican. Future studies should continue refining the identification of cenocrons and the reconstruction of a geobiotic scenario, as well as integrating ecological biogeographic studies, to allow a more complete understanding of the patterns and processes that have caused the biotic complexity of this transition zone.

“…Generalized tracks are not only recognized when there is phylogenetic evidence supporting them but, in a more general sense, they should reflect the existence of ancestral biotas (Morrone, 2015b). Similar patterns in the Mexican transition zone have been found in Coleoptera (Liebherr, 1991;Morrone & Márquez, 2001;Toledo et al, 2007).…”

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.
