RESUMEN Jalisco se localiza en el occidente de México y es una de las entidades con una alta bio­ diversidad en lo que refiere a mamíferos, esto como resultado de una serie de factores tales como su compleja orografia, y a que se encuentra en una zona de transición entre dos grandes regiones biogeográficas, la Neártica y la Neotropical. Como consecuencia y de la necesidad de contar con un documento de referencia, se recabó y analizó toda la información posible generada hasta la fecha para los taxa del orden Rodentia, así como en la revisión de ejemplares de museo del Centro de Estudios en Zoología, Universidad de Guadalajara (CEZUG). Con base en esto, se elaboró una clave ilustrada para la determinación de los roedores del Estado de Jalisco, considerando su compleja variabilidad que exhiben ciertos integrantes de este grupo, se toma como base la utilización de caracteres tanto externos (morfológicos y morfométricos) como los craneales y dentales. Asimismo, se incorpora una lista actualizada a nivel subespecifico de los roedores de Jalisco, incluyendo los cambios taxonómicos y nomenclaturales habidos recientemente. De esta manera, se hace mención de la composición de roedores de la entidad, el cual está representado por 59 especies, esto constituye aproximadamente el 35% del total de especies conocidas de mamíferos para la entidad. Para reforzar este documento, se anexan fichas descriptivas para cada uno de los taxones enlistados en este trabajo, que incorporan mapas actualizados de su distribución en el estado, así como información extensa de sus caracteres. De tal forma, se corrobora la distribución de Reithrodontomys mexicanus en Jalisco. ii CONTENIDO AGRADECIMIENTOS ..... • .. • 1 RESUMEN ..... .11 ÍNDICE DE FIGURAS ..... .iv ÍNDICE DE CUADROS. .iv ÍNDICE DE ANEXOS ... .•.

  • Body Size and Diet Mediate Evolution of Jaw Shape in Squirrels (Sciuridae)

Abstract Convergence is widely regarded as compelling evidence for adaptation, often being portrayed as evidence that phenotypic outcomes are predictable from ecology, overriding contingencies of history. However, repeated outcomes may be very rare unless adaptive landscapes are simple, structured by strong ecological and functional constraints. One such constraint may be a limitation on body size because performance often scales with size, allowing species to adapt to challenging functions by modifying only size. When size is constrained, species might adapt by changing shape; convergent shapes may therefore be common when size is limiting and functions are challenging.

Nehiba THESIS Submitted to Northern Michigan University In partial fulfillment of the requirements For the degree of MASTER OF SCIENCE Office of Graduate Education and Research July 2018 ABSTRACT By Katie R. Nehiba Current anthropogenically-driven climate change is accelerating at an unprecedented rate. In response, species’ ranges may shift, tracking optimal climatic conditions. Species-specific differences may produce predictable differences in the extent of range shifts. I evaluated if patterns of predicted responses to climate change were strongly related to species’ taxonomic identities and/or ecological characteristics of species’ niches, elevation and precipitation. I evaluated differences in predicted range shifts in well-sampled small mammals that are restricted to North America: kangaroo rats, voles, chipmunks, and ground squirrels.

While the number of recognized species in the class Mammalia has increased through time, tabulation of those increases has relied on the sporadic release of revisionary compendia like the Mammal Species of the World (MSW) series. Here, we present the Mammal Diversity Database (MDD), a digital, publically accessible, and updateable list of all mammalian species, now available online: https://mammaldiversity.org. The MDD will continue to be updated as manuscripts describing new species and higher taxonomic changes are released. Starting from the baseline of the 3rd edition of MSW (MSW3), we performed a review of taxonomic changes published since 2004 and digitally linked species names to their original descriptions and subsequent revisionary articles in an interactive, hierarchical database. We found 6,495 species of currently recognized mammals (96 recently extinct, 6,399 extant), compared to 5,416 in MSW3 (75 extinct, 5,341 extant)—an increase of 1,079 species in about 13 years, including 11 species newly described as having gone extinct in the last 500 years.

  • IRBP) in Ground Squirrels and Blind Mole Rats
    Molecular Evolution of the Interphotoreceptor Retinoid Binding Protein (IRBP) in Ground Squirrels and Blind Mole Rats Research Thesis Presented in partial fulfillment of the requirements for graduation with Research Distinction in Biology in the Undergraduate Colleges of The Ohio State University by Bethany N. Army The Ohio State University December 2015 Project Advisor: Dr. Ryan W. Norris, Department of Evolution, Ecology and Organismal Biology Abstract Blind mole rats are subterranean rodents and spend most of their lifetime underground. Because these mammals live in a dark environment, their eyes have physically changed and even the role played by their eyes has changed. The processing of visual information begins in the retina, with the detection of light by photoreceptor cells. Interphotoreceptor retinoid binding protein (IRBP) is a transport protein, which facilitates exchange between photoreceptors and retinal-pigmented epithelium. The IRBP gene has been commonly used in rodent phylogenetic analyses, so I analyzed IRBP in blind mole rats to interpret its evolution and to see if there were any changes among the amino acids in the protein. To do this I used molecular data (cytochrome b and IRBP) from two groups of rodents, the muroids and the marmotines. I constructed phylogenetic trees and interpreted the amino acid sequence of IRBP. Blind mole rats had a slower rate of evolution than expected, but there were changes along the amino acid sequence of IRBP, which may indicate that the IRBP gene is functioning in a specialized way to meet the needs of the particular lifestyle of this mammal. Introduction: Blind mole rats, subfamily Spalacinae, are burrowing mammals that spend most of their life underground.

A revision of family group names for squirrels (Rodentia: Sciuridae) uncovered a neglected name Arctomyinae Gray, 1821 which predates Marmotinae Pocock, 1923. We propose a new subtribe Ammospermophilina, to encompass the Nearctic Ammospermophilus and Notocitellus and holds a basal position in a lineage of ground squirrels and marmots. Furthermore, we reviewed the Palaearctic Arcto- myinae from the genera Urocitellus, Marmota and Sciurotamias. On the basis of published data and our own examination of 926 museum specimens we recognize 12 species and 15 subspecies: Urocitellus undulatus (two subspecies: undulatus and eversmanni), U. parryii (the only Palaearctic subspecies is leucosticus), Marmota marmota (marmota and latirostris), M. bobak, M. baibacina, M. kastschenkoi, M. sibirica, M. himalayana, M. camtschatica (camtschatica, bungei, doppelmayeri), M. caudata (caudata, aurea, dichrous), M. menzbieri (menzbieri and zachidovi), and Sciurotamias davidianus (davidianus and consobrinus). All species names (69 in total) are reviewed and linked to senior synonyms. We showed that Arctomys marmota tigrina Bechstein, 1801 is a junior synonym of M. bobak and not of M. marmota. Descriptions are provided for valid taxa, together with photographs of skins or living animals, and drawings of skulls.

It has been demonstrated that across species, the direction and magnitude of sexual dimorphism in body size often corresponds to social systems. Moreover, many animal lineages conform to “Rensch’s rule”, which states that male-biased SSD increases with body size. We tested whether considerable differences in sociality and large variation in body size were connected with the evolution of SSD in the structural body size of ground squirrels, an otherwise ecologically relatively homogenous group of terrestrial rodents. Results: We found the general trend of male-biased SSD in ground squirrels, however, male size increases nearly perfectly isometrically with female size among species and sociality does not explain departures from this relationship. Species with different sociality grades significantly differ in body size, with the most social species tending to be the largest. Conclusions: We suggest that lack of conformity with Rensch´s rule in ground squirrels may be attributed to their low variation in SSD, and briefly discuss three potential causes of small magnitude of SSD in the structural size in rodents: low selection on SSD in structural dimensions, ontogenetic and genetic constraints and the existence of ecological/selection factors preventing the evolution of extensive SSD.
