“…Palaemonetes suttkusi, and the rest of the Mexican freshwater Palaemonetes, inhabits rivers that flow into the Gulf of Mexico. For this reason it is possible that the ancestor of these species belonged to the coastal Cretaceous fauna, and that its diversification was related to the uprising of the Sierra Madre Oriental that began about 70 mya (Cevallos-Ferriz & González-Torres, 2006).…”

ABSTRACT. Palaemonid shrimps form a large and diversified group distributed primarily in marine waters. Within the family Palaemonidae the subfamily Palaemoninae is composed of 26 genera and more than 370 species inhabiting marine and fresh waters in epigean and hypogean habitats. One of the relevant questions that have emerged in relation to the subfamily is how the invasion to freshwater has occurred in Mexico, where six freshwater genera belonging to the Palaemoninae (Creaseria, Cryphiops, Macrobrachium, Palaemonetes, Neopalaemon and Troglomexicanus), are present. The purpose of this study was to explore the relationships among these freshwater lineages through a phylogenetic analysis based on partial sequences of the 16S mitochondrial gene to elucidate if these genera are closely related and derived from a common ancestor or if each lineage has invaded the freshwater habitat independently. The analysis included species representing monotypic and diversified genera, from epigean and hypogean habitats and with complete and abbreviated larval development. The results suggest that the invasion of freshwater occurred on four different occasions and that the different lineages originated before the invasions of freshwater occurred. Keywords: Palaemoninae, freshwater invasion, 16S mtDNA, phylogeny, Mexico.Relaciones filogenéticas entre los géneros de camarones palaemónidos de agua dulce (Crustacea: Decapoda) de México: ¿evidencia de invasiones múltiples?RESUMEN. Los camarones palaemónidos forman un grupo grande y diversificado distribuido principalmente en el ambiente marino. Dentro de la familia Palaemonidae la subfamilia Palaemoninae está formada por 26 géneros y más de 370 especies que habitan aguas marinas y dulces en hábitats epigeos e hipogeos. Una de las preguntas relevantes que ha emergido en relación a la subfamilia Palaemoninae es cómo ha ocurrido la invasión de especies en agua dulce, que en México, está representada por seis géneros dulceacuícolas (Creaseria, Cryphiops, Macrobrachium, Palaemonetes, Neopalaemon y Troglomexicanus). El propósito de este estudio es explorar las relaciones entre estos linajes dulceacuícolas mediante un análisis filogenético basado en secuencias parciales del gen 16S mitocondrial para determinar si estos géneros están cercanamente relacionados y derivan de un ancestro común o si cada linaje ha invadido el agua dulce independientemente. El análisis incluye especies que representan un género diversificado y monotípico, de hábitats epigeos e hipogeos, con desarrollo larval extendido y abreviado. Los resultados sugieren que la invasión del agua dulce ocurrió en por lo menos cuatro ocasiones diferentes y que los diferentes linajes se originaron antes de que la invasión del agua dulce ocurriera. Palabras clave: Palaemoninae, invasión del agua dulce, 16S mtADN, filogenia, México.

“…The geological evolution of Mexico and Central America during the Cretaceous and Cenozoic has had a significant influence on the processes controlling the composition of their biota (Cevallos-Ferriz & González-Torres, 2005). The primary geological events shaping Mexico and Central America during these time intervals include the following: (1) the development of large magmatic provinces (Sierra Madre Occidental, Trans-Mexican Volcanic Belt, and Sierra Madre del Sur); (2) the fragmentation and displacement of continental segments including the opening of the Gulf of California (the separation of the Baja California Peninsula from the mainland) and the displacement of the Chortis Block to northern Central America; (3) the marine regression that outlined the current shape of Mexico; and (4) the formation and rise of an eastern orogenic belt known as the Sierra Madre Oriental (Cevallos-Ferriz & González-Torres, 2005;Ortega-Gutiérrez et al, 1994).…”

“…Para entender los patrones de distribución de la flora actual, se observaron paralelamente los procesos geológicos que tuvieron lugar a lo largo de la historia de México que ha sido muy activa (Cevallos-Ferriz y González-Torres, 2005;Cevallos-Ferriz et al, 2012). Entender la interacción que ha existido entre las cinco placas tectónicas (placas Norteamericana, Rivera, Pacífico, Cocos y Caribe) que han configurado la fisiografía actual es indispensable para comprender la biodiversidad actual de la flora mexicana.…”
