Primer registro del murciélago platanero Musonycteris harrisoni (Chiroptera: Phyllostomidae) en Puebla, México

ResumenSe registra por primera vez al murciélago platanero, Musonycteris harrisoni para el estado de Puebla, México. Esta especie se capturó en la porción suroeste de la mixteca baja poblana, el punto más oriental en la distribución de este murciélago. Es un dato relevante, pues la especie es endémica de las selvas bajas caducifolias (SBC) de la costa del Pacífico y de la cuenca del río Balsas en México; es considerada escasa y en peligro de extinción por el gobierno de México y previamente se había registrado sólo en 6 estados del país. La distribución geográfica se extiende a ca. 74km al SE de la localidad más cercana con registro previo de la misma, en Palpan, Morelos, México. Esta investigación contiene datos morfométricos externos de un individuo, información del hábitat donde se capturó y sobre otras especies capturadas en el mismo sitio. La presencia de esta especie en la zona de estudio, representa un argumento más a favor de las acciones que el grupo de investigación del Centro de Investigación en Biodiversidad y Conservación- Universidad Autónoma del Estado de Morelos (CIByC-UAEM) lleva a cabo para promover el establecimiento de una nueva área natural protegida que salvaguarde las SBC de esta región del país.AbstractWe present here the first record of the Trumpet nosed bat Musonycteris harrisoni for the state of Puebla, Mexico. Our record of this species from the southwestern portion of the region known as Mixteca Baja Poblana is the first for Puebla and the most eastern record for the species in Central Mexico. It is a relevant datum since the species is endemic to the Tropical Dry Forests (TDF) of the Pacific coast and the Balsas River Basin in México, considered scarce and endangered by the Mexican government, and previously captured only in 6 states in the country. Our record extends its range ca. 74km SE of the closest reported locality where it was previously registered, in Palpan, Morelos, México. We provide external measurements of one individual, information about the habitat where it was captured and about other bat species recorded in the same locality. The presence of this species at the capture site gives strength to the ongoing actions of our research group from Centro de Investigación en Biodiversidad y Conservación-Universidad Autónoma del Estado de Morelos (CIByC-UAEM), to promote the creation of a new natural protected area for the conservation of TDF at this region

The Sonozotz project: Assembling an echolocation call library for bats in a megadiverse country

Bat acoustic libraries are important tools that assemble echolocation calls to allow the comparison and discrimination to confirm species identifications. The Sonozotz project represents the first nation-wide library of bat echolocation calls for a megadiverse country. It was assembled following a standardized recording protocol that aimed to cover different recording habitats, recording techniques, and call variation inherent to individuals. The Sonozotz project included 69 species of echolocating bats, a high species richness that represents 50% of bat species found in the country. We include recommendations on how the database can be used and how the sampling methods can be potentially replicated in countries with similar environmental and geographic conditions. To our knowledge, this represents the most exhaustive effort to date to document and compile the diversity of bat echolocation calls for a megadiverse country. This database will be useful to address a range of ecological questions including the effects of anthropogenic activities on bat communities through the analysis of bat sound.</p
