Aves del municipio de Ibagué - Tolima, Colombia

In order to complete the species list as well as distribution and habitat information in Ibagué, the Tolima Bird Observation Group (GOAT), has been carrying out sampling by point counts, intensive searches, strip transects, captures with mist nets (Ralph et al. 1996), and aural identification in 28 localities in the municipality of Ibagué, between 585 and 4400 m during 2004 and 2006.Con el fin de contar con un listado más completo de las aves de Ibagué y brindar información sobre su distribución y hábitat dentro del municipio, el Grupo de Observaciónde Aves del Tolima (GOAT) ha realizado muestreos por puntos, búsqueda intensiva, transectos en franjas, capturas con redes de niebla (Ralph et al. 1996) e identificación auditiva de especies de aves, en 28 localidades ubicadasentre los 540 y 4400m de altitud, durante 2004 y 2006

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
