“…Hellenthal and Price () found a general correspondence between the distribution of the then four recognized species of pocket gophers of the Thomomys subgenus Megascapheus and 8 species complexes of their chewing lice (comprising 29 species of Geomydoecus ). Advances in the understanding of evolutionary relationships within T. bottae (Belfiore et al, ; Patton & Smith, ; Smith, ) and T. umbrinus (now itself composed of four species; Hafner, Hafner, Patton, & Smith, ; Hafner, Gates, Mathis, Demastes, & Hafner, ; Mathis, Hafner, Hafner, & Demastes, ; Mathis, Hafner, Hafner, & Demastes, ; Mathis, Hafner, & Hafner, ) permit a more informed evaluation of general patterns of distributional relationships within these pocket gophers and their chewing lice.…”

We synthesize observations from 1979 to 2016 of a contact zone involving two subspecies of pocket gophers ( Thomomys bottae connectens and T. b. opulentus ) and their respective chewing lice ( Geomydoecus aurei and G. centralis ) along the Río Grande Valley in New Mexico, U.S.A., to test predictions about the dynamics of the zone. Historically, the natural flood cycle of the Rio Grande prevented contact between the two subspecies of pocket gophers. Flood control measures completed in the 1930s permitted contact, thus establishing the hybrid zone between the pocket gophers and the contact zone between their lice (without hybridization). Since that time, the pocket gopher hybrid zone has stabilized, whereas the northern chewing louse species has replaced the southern louse species at a consistent rate of ~150 m/year. The 0.2–0.8 width of the replacement zone has remained constant, reflecting the constant rate of chewing louse species turnover on a single gopher and within a local pocket gopher population. In contrast, the full width of the replacement zone (northernmost G. centralis to southernmost G. aurei ) has increased annually. By employing a variety of metrics of the species replacement zone, we are better able to understand the dynamics of interactions between and among the chewing lice and their pocket gopher hosts. This research provides an opportunity to observe active species replacement and resulting distributional shifts in a parasitic organism in its natural setting.

“…Adicionalmente, se adoptó la propuesta de Hafner et al (2007) quienes asignaron el nombre de Liomys como sinonimia de Heteromys. Se le asignó el estatus de especie valida al taxón Dipodomys phillipsi ornatus siguiendo la recomendación de Fernández et al (2012), y en lo que respecta a la clasificación y distribución del género Thomomys se siguió a Álvarez-Castañeda (2010) y Mathis et al (2013). Los tres taxa exóticos miembros de la familia Muridae se integran a este trabajo.…”

Introduction:The state of Jalisco with only 4.0 % of the national area holds about 27.0 % (64 spp) of all rodent species described for Mexico. This knowledge of the richness of rodents from Jalisco is clearly known and refers only to the publications cited the presence of a taxon inside the state border. Therefore, this paper aims to propose an illustrated key to facilitate any interested person a tool that allows them to easily recognize rodent species inhabiting the state of Jalisco. It also represents an effort that seeks to contribute to a better understanding of morphological variation that is so difficult to appreciate in this group of vertebrates. Methods: The key to the identification of rodents of Jalisco was integrated based on the compilation and analysis of bibliographic information, and review of museum specimens deposited in the mammal collection of the Centro de Estudios en Zoología, Universidad de Guadalajara (CZUG). We consider first the original literature where these taxa are described, and ensure the correct identification of the members of the rodents were considered diagnostic characters allowing species easily recognize. With the purpose of facilitating the understanding and accessibility of the key to any interested and not just specialists, have been included illustrations that accompany the text in almost all expressions of character states.

“…Later, genetic analyses revealed that those individuals represent a previously unrecognized species, Thomomys nayarensis. An adult male was designated as the holotype (Louisiana State University Museum of Natural Science, LSUMZ 36794, Mathis et al 2013). Given that pocket gophers were collected using a collecting permit issued by the Secretary, the holotype of T. nayarensis was properly sent from LSUMZ to a Mexican institution (Colección Nacional de Mamíferos, Universidad Nacional Autónoma de México, CNMA 45745).…”
