The dry forest is an ecosystem with a relatively high diversity of species. It is also one of the most threatened habitats. This research was carried out between January and November 2010 aiming to describe species richness, composition, and conservation status of the herpetofauna in the Yerbasanta micro-basin in the Central Coast of Oaxaca. Standard visual encounter surveys were used to observe herpetofaunal community in four locations of the micro-basin. Five amphibian species and 37 reptiles species were found. The Shannon-Wienner index showed that Pueblo Viejo had the highest value of diversity, followed by Unión, and the remainder localities had lower values. The similarity index was moderate between locations. Among the registered species, 12 can be classified under some conservation status. These results also suggest that this region can maintain a significant number of herpetofauna species. Additionally, this research represents baseline information that contributes to other studies.

During a 6-months research carried out in the Robles village (Jamundí municipality, Valle del Cauca Department, Colombia) in 2014, bat feces were collected to determine the diet of fruit-eating bats. This study area included farms and tropical dry forest remnants, where A. lituratus was the most generalist species, with 10 different plant species recorded in its diet, including Ficus, Psidium, Mangifera, Cecropia, and Piper species (Montoya-Bustamante et al., 2016). Within two (out of 130) different fecal samples an individual of Atta cephalotes (both workers) were found associated to Psidium guajava seeds and pulp

RESUMENLas selvas secas son uno de los ecosistemas más diversos y amenazados en Latinoamérica. Se realizó un muestreo de la mastofauna terrestre en dos localidades de las selvas secas del estado de Guerrero en el Pacífico mexicano. En total se registraron 44 especies de mamíferos terrestres que pertenecen a 20 familias y 8 órdenes, lo que representa el 9% de la mastofauna terrestre del país y el 29% para el estado de Guerrero. De las especies encontradas, 9 son endémicas a México. Sobre el estado de conservación, 3 de ellas se encuentran amenazadas y 3 en peligro de extinción de acuerdo a la lista mexicana de especies en riesgo. A nivel mundial, 2 especies son consideradas vulnerables. Destacan los registros del zorrillo pigmeo (Spilogale pygmaea), la rata leñera (Hodomys alleni) y el jaguarundi (Herpailurus yagouaroundi). Para los murciélagos Musonycteris harrisoni y Myotis carteri se amplía su rango de distribución con los registros aquí presentados. La diversidad de mamíferos registrada enfatiza la importancia de conservar parches de selva en ambientes altamente urbanizados, así como la necesidad de estrategias que incrementen la conectividad entre los diferentes parches y que consideren las amenazas urbanas a la fauna en estos sitios.Palabras clave: Acapulco de Juárez, Guerrero, mamíferos, Omitlán, selva seca.ABSTRACTThe tropical dry forest represents one of the most diverse and threatened ecosystems in Latin America. We carried out a survey of the terrestrial mammals’ community in two locations at the Mexican Pacific region of dry forest in Guerrero state. We registered 44 species of mammals belonging to 20 families and 8 orders, representing 9 % of Mexico’s terrestrial mammals and 29 % of Guerrero’s. About 9 species of the mammals reported in this study are endemic to Mexico. About the conservation status, 3 species are classified as “threatened” and 3 as “endangered” in the Mexican list of endangered species. In the global context, 2 species are listed as vulnerable. Also, the presence of the pygmy skunk (Spilogale pygmaea), the allen’s woodrat (Hodomys alleni) and the presence of the jaguaroundi (Herpailurus yagouaroundi), is noteworthy. With the records in this study, we extend the known distribution of the bats Musonycteris harrisoni and Myotis carteri. The great diversity and peculiarity of the found mammals emphasize the importance of conserve forest patches in highly urbanized, also the need of strategies that increment the connectivity between the patches and consider the urban threats, as roadkill’s, in these sites.Key words: Acapulco de Juárez, dry forest, Guerrero, mammals, Omitlan.

The Impact

<p><strong>Background:</strong> Agriculture and cattle raising modify the structure and functioning of tropical dry forest. The impact of these activities has been evaluated in regions of Jalisco and Yucatán, where slash-and-burn agriculture and extensive cattle raising are the main types of management. However, there are other regions such as Guerrero, where agriculture is combined with cattle raising. Yet, its impact on the forest has not been evaluated so far.</p><p><strong>Question:</strong> What is the impact of agriculture/cattle raising and cattle raising on the tropical dry forest in Zirándaro, Guerrero?</p><p><strong>Study sites and dates:</strong> The study was performed in Zirándaro, Guerrero, in December 2014 and June 2015.</p><p><strong>Methods:</strong> We selected 9 sites with agriculture/cattle raising, cattle raising, and forest to sample vegetation and soil, and to calculate 10 ecological indicators. We also collected 9 soil samples to evaluate their physical and chemical properties.</p><p><strong>Results:</strong> The soil of agriculture/cattle raising and cattle raising had higher bulk density, but lower porosity and organic matter content than the forest soil. The agriculture/cattle raising and cattle raising had low plant species richness and canopy cover. The agriculture/cattle raising had lower vegetation structure and higher proportion of basal gaps than cattle raising. These differences suggest that agriculture/cattle raising had a higher impact on forest than cattle raising. Yet, we did not find significant differences in most of the ecological indicators.</p><p><strong>Conclusions: </strong>The agriculture/cattle raising and cattle raising have a relatively similar ecological impact on the tropical dry forest of Zirándaro, Guerrero.<strong></strong></p>

In this study we describe the structure, floristic composition, and diversity of the tropical dry forest established on the Cerro Verde (Verde Hill), located at Nizanda (Isthmus of Tehuantepec, Oaxaca, Mexico). We censused woody plants with DBH Ɛ 1 cm (upper stratum) present in 30 100-m2 plots, and in five 4-m2 subplots within each of them, those plants with height &gt; 30 cm but &lt; 1 cm DBH (lower stratum). A total of 194 species belonging to 52 families were recorded. Species richness was identical in both strata (145 species), each contributing exclusively with ca. 25% of total recorded richness. Leguminosae was the most speciose family (27), followed by Asteraceae (20) and Euphorbiaceae (18). The most frequent species were Bursera simaruba + B. aff. cinerea (not distinguished in the field), Euphorbia schlechtendalii, Pilosocereus collinsii and Capparis verrucosa. Average richness by plot was 30 species. Mean values of indices based on species richness and abundances (Berger-Parker = 0.20;  Simpson = 0.09; Fisher’s[= 9.47; Shannon = 2.78; eveness = 0.82) indicated a high diversity and consequently a low dominance in this forest. Extrapolated values showed a total (upper + lower strata) density of 23,950 ind. ha-1 (830 ind. ha-1 with DBH Ɛ 10 cm), a forest cover of 446.7%, and a basal area of 53 m2 ha-1. Mean height of those individuals accounting for 10% of the highest trees by plot was 9.1 m. Tropical dry forest structure at Cerro Verde is comparable to other Mexican communities within the seasonally dry tropical region and indicates a good conservation status. This feature, together with its particular floristic composition, makes of this area a high priority site which requires inclusion in a formal conservation scheme.

A New Species

A new species named Agave garciaruizii is described and illustrated here. A. garciaruizii is endemic to tropical dry forest in the Itzícuaro and Apupátaro river canyons in the Chorros del Varal State Reserve, at the southern border of the states of Jalisco and Michoacán, México. It belongs to the subgenus Littaea and to the Marginatae species group and is morphologically related to A. angustiarum and A. impressa, but differs from these species in some features of leaves, inflorescences and infructescences. Its conservation status was assessed as Endangered (EN). Additionally, morphological evidence was provided in support of A. arcedianoensis as a species distinct from A. angustiarum. A key to morphologically and geographically closely related species in the Marginatae group is presented.
