The Andean Ibis () in South America: potential distribution, presence in protected areas and anthropic threats.

The avifauna of South America is one of the most widely studied groups of vertebrates. However, certain species, such as the Andean Ibis (), have received limited attention regarding their ecological patterns, biology, current distribution, and environmental requirements. This study analyzed observation data from the Global Biodiversity Information Facility (GBIF) on the Andean Ibis in four countries to identify and understand critical variables that determine the species' presence, assess the proportion of its habitat within protected areas and identify possible threats to the species.

Data: Inventory of trees in five fragments of temperate evergreen forest located on the eastern slope of Chile's coastal mountain range.

The data set comes from a tree inventory conducted in an evergreen forest fragment (dominated by and ) and four fragments dominated by . The forests are located in an agroforestry matrix landscape of the Coastal Mountain Range of the Chilean Lake District. The data collection was carried out using line transect sampling, which was traced through the core of each fragment oriented towards its longest axis.

Predicting the potential distribution of the endemic seabird in the Humboldt Current Large Marine Ecosystem under different climate change scenarios.

Background: The effects of global climate change on species inhabiting marine ecosystems are of growing concern, especially for endemic species that are sensitive due to restricted distribution. One method employed for determining the effects of climate change on the distribution of these organisms is species distribution modeling.

Methods: We generated a model to evaluate the potential geographic distribution and breeding distribution of the Peruvian pelican ().

Genetic divergence analysis of the Common Barn Owl Tyto alba (Scopoli, 1769) and the Short-eared Owl Asio flammeus (Pontoppidan, 1763) from southern Chile using COI sequence.

In this paper new mitochondrial COI sequences of Common Barn Owl Tyto alba (Scopoli, 1769) and Short-eared Owl Asio flammeus (Pontoppidan, 1763) from southern Chile are reported and compared with sequences from other parts of the World. The intraspecific genetic divergence (mean p-distance) was 4.6 to 5.

Bioenergetics and food preferences in sympatric southern Chilean rodents.

Ecological divergences in two congeneric sympatric woodland rodents, Akodon olivaceus brachiotis and Akodon longipilis apta (Family Cricetidae) was demonstrated from determination of energetic bud gets and food preferences. It was found that each species posseses a different bioenergetic strategy. The heavier (A.
