Abstract

Resumen: Los murciélagos representan un componente clave en la dinámica de ecosistemas terrestres y alcanzan altos niveles de abundancia y diversidad en el neotrópico. Las transformaciones medioambientales modulan la diversidad alfa, beta y gamma de una región, donde algunas especies se ven favorecidas y otras no, reduciendo o ampliando su presencia regional; además, constantemente se genera nueva información sistemática y es necesaria la actualización de la nomenclatura en los listados faunísticos, información básica para los programas de manejo ambiental, por ello, presentamos una lista actualizada de los murciélagos de la Reserva de la Biosfera Los Tuxtlas. El listado está basado en capturas de campo, revisión de ejemplares depositados en colecciones científicas, así como en una revisión documental de bases nacionales e internacionales. De esta manera, se confirma la presencia de 65 especies de murciélagos y se descartan 8 especies probables aún no confirmadas en la región, pero que se han mencionado en diferentes fuentes.

Abstract: Bats are a key component in the dynamics of terrestrial ecosystems and reach high levels of abundance and diversity in the Neotropics. Environmental transformations modulate alpha, beta and gamma biodiversity of a region, where some species are favored while others are not, reducing or expanding their regional presence. Also, the constant development of new systematic information requires necessary updates of the nomenclature in faunal lists. Updated information is basic for programs of environmental management and conservation. Here, we present an updated list of bats of the Los Tuxtlas Biosphere Reserve. The list is based on captures in the field, the revision of specimens deposited in collections, as well as the revision of online databases of national and international scientific collections. In this manner, we confirm the presence of 65 species of bats and discard 8 species still not confirmed in the region, but have been mentioned in various sources.

Bats and birds increase crop yield in tropical agroforestry landscapes.

Bea Maas, Yann Clough, Teja Tscharntke (2013)

Human welfare is significantly linked to ecosystem services such as the suppression of pest insects by birds and bats. However, effects of biocontrol services on tropical cash crop yield are still largely unknown. For the first time, we manipulated the access of birds and bats in an exclosure experiment (day, night and full exclosures compared to open controls in Indonesian cacao agroforestry) and quantified the arthropod communities, the fruit development and the final yield over a long time period (15 months). We found that bat and bird exclusion increased insect herbivore abundance, despite the concurrent release of mesopredators such as ants and spiders, and negatively affected fruit development, with final crop yield decreasing by 31% across local (shade cover) and landscape (distance to primary forest) gradients. Our results highlight the tremendous economic impact of common insectivorous birds and bats, which need to become an essential part of sustainable landscape management.
