Abstract Accurate distributional information is crucial for studies on systematics, biodiversity and conservation. To improve the knowledge regarding the geographical distribution of Omalonyx in South America, we present updated information based on data from a literature review, institutional collections and malacological surveys. All this information composed the dataset used to predict species distribution employing the Maximum Entropy Algorithm (MaxEnt). The model was run using data on species distribution, altitude and bioclimatic variables (WorldClim database). The model had consistent performance, and areas presenting similar conditions to areas where the species were recorded were considered areas of occurrence. The predicted occurrence areas... |

El género Polylepis es endémico de las montañas de Sudamérica. Sus especies frecuentemente dominan la canopia de bosques y arbustales cuya conservación y restauración son una prioridad a nivel continental. En Argentina, el género incluye cinco especies que se distribuyen en las montañas del centro y noroeste del país. Sus distribuciones, amenazas y estados de conservación están poco documentados e incluso existen fuertes controversias sobre el grado en que el Hombre ha impactado en la cobertura, la estructura y la distribución de estos bosques. Para contribuir a revertir esta situación confeccionamos modelos potenciales por especie que sugieren 14800 km² aptos para la presencia de al menos una de las cinco especies. Evaluamos 490 parcelas de 3600 m²... |

By-catch species from tropical tuna purse seine fishery have been affected by fishery pressures since the last century; however, the habitat distribution and the climate change impacts on these species are poorly known. With the objective of predicting the potential suitable habitat for a shark (Carcharhinus falciformis) and a teleost (Canthidermis maculata) in the Indian, Atlantic and Eastern Pacific Oceans, a MaxEnt species distribution model (SDM) was developed using data collected by observers in tuna purse seiners. The relative percentage of contribution of some environmental variables (depth, sea surface temperature, salinity and primary production) and the potential impact of climate change on species habitat by the end of the century under the A2... |
