Bibliographic records of Angola mammals

Study Extent

The study geographic extent corresponds to Angola, located along the south-western coast of Africa (4º22’S, 18º03’S). Ungulate taxa are well represented across the country, but records for rodents and carnivores are lacking in the northwest region (provinces of Zaire and Uíge) and in the southeastern regions of the country (mainly in the provinces of Moxico and Cuando-Cubango). The exact date of the records is unknown, and therefore the date of the record's publication is used as a proxy of temporal spanning. The temporal range of the dataset is 1860-1999, but the bulk of information is concentrated in the decades of 1950-1980.

Sampling

The records gathered in this dataset were compiled and published by Crawford-Cabral and colleagues and correspond to information gathered during scientific expeditions carried out in Angola during the 20th century, complemented with museum specimens and literature records revised by the authors. The records compiled were georefenced at a resolution of quarter degree cell (approximately 25x25km), following the georeferencing scheme of Crawford-Cabral and colleagues.

Quality Control

All of the records were was thoroughly scan for potential error, with a particular emphasis on potential misallocation of observation records.

Method steps

1. Information was collected from the following publications: Crawford-Cabral J (1998) The Angola rodents of the superfamily Muroidea. An account on their distribution. Estudos Ensaios e Documentos, 161. Instituto de Investigação Científica Tropical. Lisboa. Crawford-Cabral J, Simões AP (1987) Distributional data and notes on Angolan carnivores (Mammalia: Carnivora) I – Small and medium-sized species. Garcia de Orta, Série de Zoologia 14: 3-27. Crawford-Cabral J, Simões AP (1988) Distributional data and notes on Angolan carnivores (Mammalia: Carnivora) II – Larger species. Garcia de Orta, Série de Zoologia 15: 9-20. Crawford-Cabral J, Veríssimo LN (2005) The ungulate fauna of Angola. Systematic list, distribution maps, database report. Estudos Ensaios e Documentos, 163. Instituto de Investigação Científica Tropical. Lisboa. All records listed in the publications were introduced into a database file. Each records was assigned to a quarter-degree grid cell. Information was georeferenced in the Camacupa projection and then projected to WGS 1984.

The taxonomic coverage of the dataset includes 140 taxa (species and subspecies) of the orders Carnivora, Rodentia, Artiodactyla, Hyracoidea, Perissodactyla, Proboscidea, Sirenia, Tubulidentata. Ungulates are the group best represented, with largest number of records (7053) followed by rodents (2037) and carnivores (789).
