Rodentia: Cricetidae) in Ecuador Jorge Brito, Germán Tenecota, and Glenda M www.mastozoologiamexicana.org La Portada La rata canguro (Dipodomys merriami) es una de las especies más representativas de las regiones desérticas de México y del sur de las Estados Unidos. En particular D. merriami es la que tiene la distribución más amplia incluyendo desde la región centro de México hasta el sur de los Estados Unidos. También es una especie que cuenta con dos poblaciones restringidas a las islas de San José y Margarita, ambas están consideradas en peligro de extinción. Sus poblaciones cuentan con pocos individuos y tienen fuertes presiones de conservación por la presencia de Gatos ferales (Fotografía de Sergio Ticul Álvarez Castañeda). Nuestro logo “Ozomatli” El nombre de “Ozomatli” proviene del náhuatl se refiere al símbolo astrológico del mono en el calendario azteca, así como al dios de la danza y del fuego. Se relaciona con la alegría, la danza, el canto, las habilidades. Al signo decimoprimero en la cosmogonía mexica. “Ozomatli” es una representación pictórica de los mono arañas (Ateles geoffroyi). La especie de primate de más amplia distribución en México. “Es habitante de los bosques, sobre todo de los que están por donde sale el sol en Anáhuac. Tiene el dorso pequeño, es barrigudo y su cola, que a veces se enrosca, es larga. Sus manos y sus pies parecen de hombre; también sus uñas. Los Ozomatin gritan y silban y hacen visajes a la gente. Arrojan piedras y palos. Su cara es casi como la de una persona, pero tienen mucho pelo.” THERYA Volumen 7, número 3 septiembre 2016 EDITORIAL The current status of micro endemic species of mammals and their prospects of conservation in southern Mexico Consuelo Lorenzo, Miguel Briones-Salas, Sergio Ticul Álvarez-Castañeda 353 ARTICULOS Influence of vegetation type and season on rodent assemblage in a Mexican Contenido temperate forest mosaic Rafael Flores-Peredo, and Guillermo Vázquez-Domínguez 357 Ethology may be related to the genetic structure of a population: Chaetodipus siccus as a study case Eduardo Felipe Aguilera-Miller 371 Influence of the composition and structure of modified landscapes on abundance of two marsupials during the dry season Bárbara Cruz-Salazar, Lorena Ruiz-Montoya, Darío Navarrete-Gutiérrez, and Luis- Bernardo Vázquez 393 Distribution and current state of knowledge of Hoffmann’s two-toed sloth (Choloepus hoffmanni) in Colombia, with comments on the variations of its external morphological traits Tinka Plese, Nicolás Reyes-Amaya, Leyn Castro-Vásquez, Sebastian Giraldo, and Orlando Feliciano 407 Diet composition and selection of the bighorn sheep (Ovis canadensis) in Sierra El Mechudo, Baja California Sur, Mexico Israel Guerrero-Cárdenas, Sonia Gallina, Pablo Corcuera, Sergio Álvarez-Cárdenas, and Rafael Ramírez-Orduña 423 Overlap in activity patterns between big cats and their main prey in northern Quintana Roo, Mexico Dulce María Ávila-Nájera, Cuauhtémoc Chávez, Marco Antonio Lazcano-Barrero, Germán David Mendoza, and Sergio Perez-Elizalde 439 A new species of grass mouse, genus Akodon Meyen, 1833 (Rodentia, Sigmodontinae), from the central Peruvian Yungas Carlos F.

  • Rodentia: Cricetidae: Sigmodontinae) in São Paulo State, Southeastern Brazil: a Locally Extinct Species?
    Volume 55(4):69‑80, 2015 THE PRESENCE OF WILFREDOMYS OENAX (RODENTIA: CRICETIDAE: SIGMODONTINAE) IN SÃO PAULO STATE, SOUTHEASTERN BRAZIL: A LOCALLY EXTINCT SPECIES? MARCUS VINÍCIUS BRANDÃO¹ ABSTRACT The Rufous-nosed Mouse Wilfredomys oenax is a rare Sigmodontinae rodent known from scarce records from northern Uruguay and south and southeastern Brazil. This species is under- represented in scientific collections and is currently classified as threathened, being considered extinct at Curitiba, Paraná, the only confirmed locality of the species at southeastern Brazil. Although specimens from São Paulo were already reported, the presence of this species in this state seems to have passed unnoticed in recent literature. Through detailed morphological ana- lyzes of specimens cited in literature, the present work confirms and discusses the presence of this species in São Paulo state from a specimen collected more than 70 years ago. Recently, by the use of modern sampling methods, other rare Sigmodontinae rodents, such as Abrawayomys ruschii, Phaenomys ferrugineous and Rhagomys rufescens, have been recorded to São Paulo state. However, no specimen of Wilfredomys oenax has been recently reported indicating that this species might be locally extinct. The record mentioned here adds another species to the state of São Paulo mammal diversity and reinforces the urgency of studying Wilfredomys oenax. Key-Words: Atlantic Forest; Scientific collection; Threatened species. INTRODUCTION São Paulo is one the most studied states in Brazil regarding to fauna.

No change recommended. http://www.fws.gov/ecos/ajax/docs/five_year_review/doc3221.pdf (853 KB) DESCRIPTION The salt marsh harvest mouse ( Reithrodontomys raviventris ), also known as the "red-bellied harvest mouse," is a small native rodent in the Cricetidae family, which includes field mice, lemmings, muskrats, hamsters and gerbils. There are two subspecies: the northern ( R. r. halicoetes ) and southern ( R. r. raviventris ). The northern subspecies lives in the marshes of the San Pablo and Suisun bays, the southern in the marshes of Corte Madera, Richmond and South San Francisco Bay. (See field identification below) The scientific name Reithrodontomys raviventris means "grooved-toothed mouse with a red belly." Both subspecies do have grooved upper front teeth but generally only the southern subspecies has a cinnamon- or rufous-colored belly. Salt marsh harvest mice are critically dependent on dense cover and their preferred habitat is pickleweed (Salicornia virginica). Harvest mice are seldom found in cordgrass or alkali bulrush. In marshes with an upper zone of peripheral halophytes (salt-tolerant plants), mice use this vegetation to escape the higher tides, and may even spend a considerable portion of their lives there.

  • Sex Bias of Small Mammals Captured in Sherman Live Traps
    Sex bias of small mammals captured in Sherman live traps Stephanie J. Pattison, West Texas A&M University undergraduate Dr. Raymond Matlack, West Texas A&M Associate Professor, and advisor ABSTRACT The sex ratios and the possibility of capture bias varies from species to species. By looking at results from other papers and comparing the juvenile sex ratio to the adult sex ratio you can determine if the bias towards one sex is a trapping bias or just the population’s sex ratio. Peromyscus leucopus, Sigmodon hispidis, Reithrodontomys montanus, Chaetodipus hispidus, Onychomys leucogaster, Neotoma micropus, Baiomys taylori, Reithrodontomys megalotis, and Peromyscus maniculatus were the species used in this study. Other species were present in the data but the sample sizes were to small to use. Several species seemed to have trap biases while others seemed to only represent population sex ratios. Peromyscus leucopus was found to have a trapping bias towards male, though this could change over time. Sigmodon hispidus seemed to have a female biased population but did not seem to have a trapping bias. Reithrodontomys montanus seemed to have a male biased population and no trapping bias. Chaetodipus hispidus seemed to have a trapping bias towards females. Onychomys leucogaster seemed to only have a population sex bias and not a trapping bias. Neotoma micropus seemed to have a female biased population and no trapping bias. Baiomys taylori seemed to have an extremely female biased population but not a trapping bias. For Reithrodontomys megalotis it could not be determined if there was a trapping bias because of unavailability of data.

Holoubek and William E. Jensen Department of Biological Sciences, Emporia State University, 1200 Commercial Ave, Emporia, KS 66801 Oak savanna, once widespread across central North America, has functionally vanished from most of its range. Our objective was to quantify avian habitat associations across a gradient from open-canopy oak savanna to closed-canopy forest in the Cross Timbers region of southeastern Kansas. Using 2012 point-count data, we modeled species-specific detection (p) and occupancy (ψ) probabilities against vegetative variables using program Presence. We first established the best p predictors and then used these when modeling ψ. Of 28 species modeled, ψ for 7 was strongly associated with vegetative variables. Occupancies of Contopus virens, Polioptila caerulea, and Passerina cyanea peaked at intermediate tree densities or canopy coverages. Icterus spurius, Spiza americana, and Spizella pusilla occupancies were highest at low tree densities or canopy coverages. These species might benefit from reductions in tree density within otherwise closed-canopy forest. Moderate habitat relationships with ψ were found for three other species. Point counts will resume in 2013. Quantifying bird habitat use in oak savanna will be useful in guiding future savanna restoration for avian conservation. Roble Sabana, una vez extendido a traves de Norte America central, ha funcionalmente desaparecido en la mayoria de su extension.

    Memoria de la Fundación La Salle de Ciencias Naturales 2012 (“2010”) 173-174: 173-238 Lista actualizada y comentada de los mamíferos de Venezuela Javier Sánchez H. y Daniel Lew Resumen. Se presenta una lista actualizada de los mamíferos de Venezuela que incluye 390 especies –agrupadas en 14 órdenes, 47 familias y 184 géneros–, 30 de ellas (7,7%) endémicas para el país. Se señalan cambios relevantes posteriores a la última actualización de los mamíferos del mundo en cuanto al conocimiento de la taxonomía y distribución de las especies venezolanas, sobre la base de detalladas consideraciones taxonómicas que justifican los cambios propuestos. Se hace un recuento histórico de la mastozoología en Venezuela con el reconocimiento de los aportes más relevantes. Se incluye un análisis de la tasa de descripción de los taxones presentes en Venezuela (no necesariamente con localidades típicas en el país), revelando un incremento promedio de 9,7 especies por década en los últimos 110 años. Se analiza la representatividad de la mastofauna de Venezuela respecto a las diferentes jerarquias taxonómicas conocidas para el mundo encontrando, entre otras cosas, que el 7,2% de todas las especies descritas a nivel global han sido registradas en el país (7,7% si se consideran solo los 14 órdenes presentes en Venezuela). Se compara la riqueza de este grupo en Venezuela respecto a los países del norte de Suramérica (Ecuador, Colombia, Guyana, Guayana Francesa y Surinam). Palabras Clave. Mammalia. Riqueza. Taxonomía.
