Variaciones de la masa corporal del gato montés (Oncifelis geoffroyi)

We report new data on the intersexual and geographical variation in body mass of the Geoffroy’s cat(Oncifelis geoffroyid’Orbigny and Gervais 1844), a little known small cat from South America, and combinethem with the existing information to compare alternative hypotheses for variation in body mass. Most dataon the body mass of O. geoffroyihave been obtained from previous research on this felid in four study areasof southern Brazil and central and southern Argentina. These data were added to those reported for other threeadditional locations. Our results set the body mass of O. geoffroyito 4.26 ±1.03 kg (mean ±SD, n = 56). Wealso show that males generally are heavier than females throughout most of this species’ distributional range.Body mass dimorphism is 1.34 on average, but ranges from 1.19 and 1.21 in Uruguay and southern Chile,respectively, to 1.76 in the northern Pampas of Argentina. When data from the best sampled areas areconsidered (Torres del Paine, Lihué Calel, southern Pampas, Campos del Tuyú and southern Brazil), onlymale body mass varies with geographic location. More intriguingly, no correlation was found between bodymass and latitude. Our results suggest a smaller mean weight of O. geoffroyirelative to what was previouslypublished, but also suggest a wider variation. Our analysis do not support Bergmann’s rule, according towhich the largest individuals would occur in the southernmost regions of this cat’s geographic distribution,while they seem supportive of a sexually-selected process affecting sexual size dimorphism in the Geoffroy’scat.Se reportan nuevos datos sobre la variación intersexual y geográfica de la masa corporal en el gato montés(Oncifelis geoffroyid’Orbigny and Gervais 1844), un félido pequeño y poco conocido de América del Sur, ylos combinamos con la información existente para evaluar dos hipótesis que explicarían esta variación. Lamayor parte de los datos sobre masa corporal de O. geoffroyifueron obtenidos en el marco de proyectos deinvestigación sobre este félido en cuatro áreas del sur de Brasil y centro y sur de Argentina. Estos datos seagregaron con registros para otras tres localidades. Nuestros resultados establecieron que la masa corporalpromedio de O. geoffroyifue de 4,26 kg (DE = 1,03 kg; n = 56). Demostramos además que los machos sonmás grandes que las hembras, y que este dimorfismo sexual ocurre en la mayoría de las localidadesmuestreadas a lo largo del rango de distribución de esta especie. El dimorfismo sexual en la masa corporal fuede 1,34 en promedio, pero varió entre 1,19 y 1,21 en Uruguay y Chile meridional, respectivamente, hasta 1,76en la Pampa septentrional argentina. Al comparar los datos de las cinco localidades con mayor número deregistros (Torres del Paine, Lihué Calel, Pampas meridionales, Campos del Tuyú y Brasil meridional) seencontró variación geográfica significativa solo en la masa corporal de los machos. No se registró unacorrelación positiva entre la masa corporal y la latitud. Estos resultados sugieren que el tamaño promedio deO. geoffroyies menor que lo sugerido por registros anteriores, pero también sugieren que su variabilidad esmayor. Nuestro análisis no apoya la regla de Bergmann en cuanto a que los individuos más grandes seencontrarían en las regiones más meridionales de la distribución geográfica, mientras que sí apoyan unescenario de selección sexual para el dimorfismo sexual en el tamaño observado en este felino.Fil: Lucherini, Mauro.

II. Conflictos entre felinos y humanos en América Latina.

Este libro contó con el liderazgo del Instituto Humboldt y de las Fundaciones Herencia Ambiental Caribe y Panthera. En 32 capítulos se recoge el esfuerzo de 77 instituciones y 110 autores que representan 18 países y abordan el conflicto entre humanos y felinos en América Latina. Es la compilación más completa que se ha elaborado acerca del tema en Latinoamérica, involucrando el análisis, la planificación, el manejo y la resolución de los conflictos entre humanos y felinos.BogotáCiencias de la Biodiversida

Neotropical xenarthrans: a dataset of occurrence of xenarthran species in the Neotropics.

International audienceXenarthrans—anteaters, sloths, and armadillos—have essential functions forecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosys-tem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts withdomestic dogs, these species have been threatened locally, regionally, or even across their fulldistribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths.Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae(3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data onDasypus pilo-sus(Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized,but new genetic studies have revealed that the group is represented by seven species. In thisdata paper, we compiled a total of 42,528 records of 31 species, represented by occurrence andquantitative data, totaling 24,847 unique georeferenced records. The geographic range is fromthe southern United States, Mexico, and Caribbean countries at the northern portion of theNeotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regardinganteaters,Myrmecophaga tridactylahas the most records (n=5,941), andCyclopessp. havethe fewest (n=240). The armadillo species with the most data isDasypus novemcinctus(n=11,588), and the fewest data are recorded forCalyptophractus retusus(n=33). Withregard to sloth species,Bradypus variegatushas the most records (n=962), andBradypus pyg-maeushas the fewest (n=12). Our main objective with Neotropical Xenarthrans is to makeoccurrence and quantitative data available to facilitate more ecological research, particularly ifwe integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, andNeotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure,habitat loss, fragmentation effects, species invasion, and climate change effects will be possiblewith the Neotropical Xenarthrans data set.
