This is the first report of chiropterophily within the genus Tillandsia. The results on the pollination biology of this bromeliad suggest an ongoing evolutionary switch from pollination by birds or moths to bats.

This paper presents an exhaustive review of the current knowledge on pollination of Araceae genera with bisexual flowers. All available studies on floral morphology, flowering sequence, floral scent, floral thermogenesis, floral visitors, and pollinators were carefully examined, with emphasis on the species-rich genera Anthurium Schott, Monstera Adans., and Spathiphyllum Schott. Genera with bisexual flowers are among the early-diverging lineages in Araceae, but present adaptations in their floral ecology to a great variety of pollination vectors, such as bees, beetles, flies, and, unusually, wind. These clades have developed highly derived pollination systems, involving the use of floral scent as a reward. We conclude that floral scent chemistry plays a key role in the pollination biology of the plants and that, in some genera, reproductive isolation through variation in the emitted floral volatile compounds may have been the decisive factor in the speciation processes of sympatric species.

Resumen. Se presenta un análisis de la bibliografía publicada en 110 años (1900 a 2010) sobre los mamíferos terrestres de la península de Yucatán y la composición de especies reconocida para Campeche, Yucatán y Quintana Roo, así como su endemicidad y estado de conservación. Se consideran las referencias publicadas en revistas científicas periódicas, libros y capítulos de libros. Se elaboró una base de datos que incluye: autor, año, década, taxón, entidad federativa, tema principal y nacionalidad del autor de la literatura revisada. No se incluyen especies marinas, extintas, introducidas y domésticas. Se identifican las especies endémicas a la región, México y Mesoamérica, así como su categoría de riesgo nacional e internacional. El registro total de referencias fue de 633, la mayoría de Yucatán. Los murciélagos fueron el orden más estudiado. Los temas más abordados fueron taxonomía y filogenia, y la mayor producción ha sido extranjera. Se documentaron 123 especies en la península, Quintana Roo 108, Campeche 103 y Yucatán 100, 34 endémicas y 41 en riesgo. Se detectaron vacíos de información sobre los mamíferos terrestres en diferentes temáticas y se identificó la necesidad de estimular estudios detallados que amplíen el conocimiento de éstos en la península de Yucatán.

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.
