Abstract:Several studies have evaluated the short-term effects of tropical forest fragmentation on plant taxonomic diversity, while only a few have evaluated its effects on functional or phylogenetic diversity. To our knowledge no study has looked at the long-term consequences of tropical forest fragmentation on the three main components of plant diversity simultaneously: taxonomic, functional and phylogenetic diversity. We sampled the vascular flora using belt transects (50 × 4 m) in a continuous tropical semi-evergreen forest (16 transects) and in an adjacent naturally fragmented forest (fragments of 1.7-My-old semi-evergreen forest immersed in a mangrove/sedge matrix) (18 transects), and compared their taxonomic, functional and phylogenetic plant diversity. There were 36 species in the continuous forest and 28 in the fragmented forest. Continuous forest was taxonomically more diverse (25%) than the fragmented forest. All functional diversity metrics were greater (6–33%) in the continuous than in the fragmented forest. Phylogenetic diversity was 19% greater and phylogenetically more overdispersed in the continuous forest than in the fragmented forest. The results suggest that in the fragmented forest not only is taxonomic plant diversity lower, but functional and phylogenetic diversity are as well. The negative effects of forest fragmentation on plant diversity seem to be chronic.

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.

The most diverse orders are Chiroptera, Cetacea, and Rodentia, while the genera with the highest numbers of species are Balaenoptera and Stenella. In terms of distribution, 21 species are endemic to Mesoamerica and six to Mexico. In Yucatan, there are 51 species listed as being at risk under Mexican legislation, while 38 are included in the Convention on International Trade in Endangered Species and 15 are threatened globally. The status of the knowledge of the mammals of Yucatan is established and the importance of relating their diversity and distribution to existing legal instruments designed for their protection, conservation and sustainable use is proposed. Key words: Distribution, endemism, mammalogy, richness, risk, systematic list.

Capturamos murciélagos del 2010 al 2012 en una selva alta perennifolia, un acahual, plantaciones de hule y en cuevas. Se revisaron 378 murciélagos pertenecientes a 26 especies de las familias Natalidae, Mormoopidae, Phyllostomidae y Vespertilionidae, de los cuales 251 se encontraron parasitados. Se recolectaron 616 ejemplares pertenecientes a 32 especies moscas. Se obtuvieron 4 nuevos registros de especies para México: Mastoptera minuta Costa Lima, Trichobius flagellatus Wenzel, Strebla chrotopteri Wenzel (Streblidae) y Basilia ortizi Machado-Allison (Nycteribiidae). También se amplía la distribución en el país para Megistopoda aranea Coquillett,

Hábitos alimenticios de la nutria neotropical (Lontra longicaudis annectens) (Carnivora: Mustelidae) en la zona costera de Tuxpan, Veracruz Feeding habits of the neotropical otter (Lontra longicaudis annectens) (Carnivora: Mustelidae) in the coastal zone of Tuxpan, Veracruz

El uso combinado de diferentes métodos de muestreo de ensambles de murciélagos se ha incrementado en las últimas décadas. El objetivo de este estudio fue evaluar la eficiencia de los inventarios de murciélagos comparando los parámetros del ensamble (riqueza de especies, abundancia y composición) usando los 3 métodos de captura convencionales (redes de niebla a nivel de sotobosque y sub-dosel, y trampas arpa), en una selva baja caducifolia de Yucatán, México. En las redes de sotobosque se registraron solamente especies de filostómidos, principalmente especies frugívoras y nectarívoras; mientras que en las trampas arpa, la mayoría fueron especies insectívoras de otras familias. Nuestros resultados indican que para el orden Chiroptera la combinación más eficiente de métodos de captura es el uso simultáneo de redes de sotobosque y trampas arpa. Sin embargo, se alcanza un inventario confiable de filostómidos sólo con las redes de sotobosque. Además, una combinación de redes de sotobosque y sub-dosel no provee una eficiente estrategia de muestreo. Palabras clave: inventarios de biodiversidad, Chiroptera, redes de niebla, trampas arpa, selva baja caducifolia, Yucatán.

Propágulos deMangrove species propagules represent a particular survival and dispersal strategy. Unfortunately, some reports have stated that Rhizophora mangle propagules are frequently attacked by Coleoptera and Lepidoptera before and after their dispersion period. The beetle species Coccotrypes rhizophorae is an obligate parasite that can cause mortality in propagules and seedlings of R. mangle, and may modify the structure of its populations. Because of the importance on this mangrove species, survival and increasing human impacts in the area, this study evaluated the presence of propagules with C. rhizophorae boring evidence in the Tumilco mangrove, in Veracruz State, Mexico. For this, three sampling areas were established: 1) mangrove core of R. mangle, 2) most impacted edge of an unpaved road with R. mangle and A. germinans, and 3) edge with Typha latifolia and R. mangle; in each area, three 25x25 m random plots were analyzed. The number of bored propagules per site was recorded every 15 days over a sampling period of one year (n= 567) from January to December 2012. We also observed the damaged part of the propagule (basal, central, apical) and the number of live and dead bored propagules per season, and compared results for different seasons in the area: rainy, cold northerly fronts or "norte" and dry. Insects were identified by an expert. Our results showed that a higher number of bored propagules was observed during the dry season, mainly in zones 2 and 3. Survival of bored propagules was higher when the perforation occurred in the basal part of the plant, and during the dry and norte seasons. Study zone 2 in particular presented a higher number of live propagules when the damage occurred in the basal part of the propagule. In all three zones, mortality was higher when the damage was apical. Zones 1 and 3 presented higher propagule survival during the dry season, while survival in zone 2 was higher during the rainy and norte seasons. The number of propagules decreased with rising flooding levels. The results showed that C. rhizophorae has a wide distribution in the Tumilco mangrove, but the mortality of R. mangle propagules is influenced by the part of the propagule that suffers damage, as well as by the season of the year and the characteristics of the area in which the infestation occurs. Futher studies are required to evaluate the impact of propagule mortality on the population structure of R. mangle. Rev. Biol. Trop. 65 (3): 1120-1128. Epub 2017 September 01.
