Bat species richness in the region of the Central Valleys of Oaxaca, MexicoAcronym: MCNB:Garcia-Luis_et_al_2019
We present a revised checklist of bat species occurring in the semi-urbanized region of the Central Valleys of Oaxaca, Mexico. The checklist is based on surveys using mist nets, echolocation calls recordings, literature and museum databases. Results show that the Central Valleys of Oaxaca have a species richness of 33 bat species belonging to 22 genera and five families. Species like the Mustached bat Pteronotus parnellii, the Western Red bat Lasiurus blossevillii and the Free-tailed bat Promops centralis were recorded after 32, 30 and 19 years respectively according to the records of the literature; also we recorded four species classified in some risk category by either the Mexican government's (NOM-059) or the IUCN's red list. The echolocation calls recordings are the first made for the region of Central Valleys of Oaxaca. Bat diversity in the Central Valleys of Oaxaca was underestimated and underlines the need of further research.
The region of the Central Valleys is located in the State of Oaxaca, Mexico (95°54’ to 97°14’W and 16°28’ to 17°38’ N). This region has an area of 7,974 km2 and incudes the political districts of Etla, Centro, Zaachila, Ocotlán, Zimatlán, Tlacolula and Ejutla. The region of the Central Valleys of Oaxaca includes the physiographic subprovince of the Central Valleys and parts of physiographic subprovinces of the Sierra Madre of Oaxaca, Fosa of Tehuacan, Central Mountains and Valleys, Western Mountains and Southern Mountains and Valleys. The climate of the region is semi-warm, sub-humid temperate and warm semi-arid. The area has been transformed to agriculture and pastureland, but hilly areas still have dry forest and pine-oak forest.
Species accumulation curves were created with Species Accumulation Functions software (CIMAT, 2003). Previously, the samples were randomized 1,000 times with EstimateS software (Colwell, 2009) in order to prevent order effect and to smooth the curve (Moreno and Halffter, 2000).
Finally, we consulted the mammal collection database of the CIIDIR-Oaxaca, which contains records of four national museums and 23 international museums (Briones-Salas et al., 2015) to obtain records of bat species for the region of the Central Valleys of Oaxaca. Guilds of bats were obtained from Ceballos and Oliva (2005), and scientific names for bat species were searched on the list of threatened species of the Norma Oficial Mexicana 059 (NOM-059-ECOL-2010; SEMARNAT, 2010) and the red list of the International Union for Conservancy of Nature (IUCN, 2016). Taxonomic arrangement is based on Ramírez-Pulido et al. (2014).
