“…The coypu (Myocastor coypus [Molina, 1782]) is a large, semi-aquatic, invasive rodent native to South America south of 23° latitude (Ehrlich 1967;Woods et al 1992). The native range includes southern Brazil, Bolivia, Paraguay, Uruguay, Argentina, and central and southern Chile (Gosling and Baker 1991).…”

NeoBiota 32: 107-125. https://doi.org/10.3897/neobiota.32.8884 AbstractInvasive species provide a unique opportunity to evaluate factors controlling biogeographic distributions; we can consider introduction success as an experiment testing suitability of environmental conditions. Predicting potential distributions of spreading species is not easy, and forecasting potential distributions with changing climate is even more difficult. Using the globally invasive coypu (Myocastor coypus [Molina, 1782]), we evaluate and compare the utility of a simplistic ecophysiological based model and a correlative model to predict current and future distribution. The ecophysiological model was based on winter temperature relationships with nutria survival. We developed correlative statistical models using the Software for Assisted Habitat Modeling and biologically relevant climate data with a global extent. We applied the ecophysiological based model to several global circulation model (GCM) predictions for mid-century. We used global coypu introduction data to evaluate these models and to explore a hypothesized physiological limitation, finding general agreement with known coypu distribution locally and globally and support for an upper thermal tolerance threshold. Catherine S Jarnevich et al. / NeoBiota 32: 107-125 (2017) 108 coypu predicted distribution among GCMs, but had general agreement of increasing suitable area in the USA. Our methods highlighted the dynamic nature of the edges of the coypu distribution due to climate non-equilibrium, and uncertainty associated with forecasting future distributions. Areas deemed suitable habitat, especially those on the edge of the current known range, could be used for early detection of the spread of coypu populations for management purposes. Combining approaches can be beneficial to predicting potential distributions of invasive species now and in the future and in exploring hypotheses of factors controlling distributions.

:The study was carried out to understand the inhabiting status and biological features of nutria (Myocastor coypus) in the Jeju Island from May, 2013 to August, 2016. Five individuals were captured by traps and two individuals were collected in dead. Of the 7 individuals, those whose bio-information could not be known were excluded to perform autopsy of the rest of them. The results from morphological, cranial and anatomical analyses, it was found that the females achieved sexual maturation but had no breeding experience. An adult male showed similar sizes to those Research Paper

IntroducciónLas asociaciones de vertebrados fósiles colectadas en la Región Pampeana (provincia de Buenos Aires, Argentina) han sido consideradas las más completas muestras del Pleistoceno Sudamericano.Con el objetivo de dar cuenta de los procesos involucrados en la configuración de éstas particulares asociaciones de vertebrados, cómo estos transformaron la información biológica original, y cómo pueden afectar las interpretaciones y resultados bioestratigráficos y paleoecológicos, se está desarro- RESUMENSe da a conocer un nuevo modo tafonómico reconocido en un sistema fluvial ubicado en la Región Pampeana (provincia de Buenos Aires, Argentina). Éste se encuentra asociado a cavidades verticales (marmitas) desarrolladas en terrazas del canal principal del río Quequén Grande. Se estudió una asociación de vertebrados actuales (en su mayoría de hábitos acuáticos) acumulados en estas cavidades, las cuales actuaron como trampas para los especímenes. El estudio de la muestra y observaciones realizadas in situ, sugieren que dicha trampa acumuló individuos completos (vivos o muertos) y especíme-nes aislados durante eventos de alto régimen hídrico (lluvias torrenciales). La representación de partes anatómicas indica una selección de elementos. Se comparó la supervivencia diferencial de cada elemento con diferentes variables (densidad ósea estructural, representación original en el esqueleto, tamaño, forma y volumen), concluyendo que la selección observada se produjo por la capacidad de flotación de los elementos ausentes (p. ej., vértebras).Palabras clave: Modos tafonómicos, trampas, marmitas, actualismo, Región Pampeana. ABSTRACTWe describe a new taphonomic mode from a fluvial system developed in channel terraces located at the Pampean Region (Quequén Grande River, Buenos Aires, Argentina) associated with natural vertical cavities («marmits»). We analyzed a recent (mainly aquatic) vertebrate assemblage accumulated in these cavities, which operate as bone traps. Our observations suggest that these traps have accumulated isolated specimens and live or dead complete individuals during high hydric regime (torrential rains). Skeletal part representation indicates that exists a bone selection. We compare the element differential survey with different variables (structural bone density, original representation in a skeleton, size, form and volume), concluding that selection was associated with floating capabilities of missing bones (e.g. vertebrae).
