Resumen: Se determinó la estructura y el contenido de las madrigueras de Liomys pictus por tipo de vegetación y temporada del año, en dos selvas tropicales del Pacífico Mexicano. Se encontraron 24 madrigueras: en la selva baja la mayoría son complejas, mientras que  en la selva mediana son lineales, por consiguiente y de acuerdo a la clasificación de las madrigueras, en selva baja se presentaron madrigueras múltiples y en selva mediana madrigueras simples. De acuerdo al contenido, las de selva baja tienen en promedio una mayor cantidad de materiales en comparación a las de selva mediana. Se catalogaron un total de 248 especies de plantas de estas 50 se comparten en ambos sitios, del total de las especies se llegaron a identificar sólo 77. Las familias más representativas fueron Leguminoseae, Euphorbiaceae y Convolvulaceae. La estructura de las madrigueras no esta determinada por la temporalidad, sin embargo el contenido esta determinado con la cantidad de material almacenado aunque la producción de semillas esta definido por el patrón de fructificación que esta dado a lo largo del año.Palabras clave: Madrigueras, estructura, contenido, Liomys pictus, Jalisco, México.Abstract: We determined the structure and contents of burrows of Liomys pictus by vegetation type and season in two tropical forests of the Mexican Pacific. 24 burrows were found in the tropical dry forest and most complex, in the semi deciduous forest is linear, and therefore according to the classification of the burrows in the tropical dry forest are more numerous and simple in the semi deciduous forest. According to the content, of the tropical dry forest have on average a greater amount of material compared to the semi deciduous forest. Were categorized a total of 248 plant species of these 50 sites are shared in both the total number of species is to determine 77. The most representative families were Leguminoseae, Euphorbiaceae and Convulvolaceae. The structure of the burrows is not affected by the timing, but the content is determined with the amount of stored material but seed production is defined by the pattern of fruit that is given throughout the year.Key words: Burrows, structure, food hoarding, Liomys pictus, Jalisco, Mexico.

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.

A New Species

Background and Aims: Hymenochaete is the genus with the highest number of species of the family Hymenochaetaceae in Mexico; 25 species have been described. It is characterized by its mainly resupinate basidiome, although it may be pileate and stipitate, of brown colors, with presence of setae and xanthocroid reaction. The objective of this study is to describe a new species of Hymenochaete.Methods: The fresh material was studied and described macro and micromorphologically, using a stereoscopic and optical microscope, taking photos in situ. Vouchers of the herbaria ENCB y FCME were studied, and specialized literature was reviewed for its description.Key results: Hymenochaete liliae sp. nov. is characterized by a resupinate, adnate, fleshy basidiome, smooth hymenophore, with numerous setae, determinate margin, abrupt, with monomitic hyphal system, simple septae; abundant subfusiform setae in the hymenium, 69-80 × 6-8 µm, acute, with crystals; and ellipsoid basidiospores, thin-walled, 5-8 × 2-3 µm. Although it resembles H. rhabarbarina, it can be differentiated by setae covered with crystals and spores of 4.8-6 × 2.3-3.3 µm. It could also be confused with H. minuscula due to its basidiome color; however, the setae are smaller (40-60 µm), as well as the basidia (15-20 µm). It can be separated from H. cinnamomea because it does not present a stratose basidiome; setae with crystals, 69-80 × 6-8 µm; basidiospores 5-8 × 2-3 µm, ellipsoidal.Conclusions: Hymenochaete liliae is proposed as a new species, which is distributed in the tropical dry forest of the state of Oaxaca, and until now only reported from the type locality.

Floristic Data

The Zimatan region of Oaxaca is characterized by the occurrence of several vegetation types and a large floristic diversity, primarily due to the large elevational range that it encompasses (from sea level to 2,580 m). In 1991 this region was proposed as a high-priority area for conservation in Oaxaca State, largely due to its extensive, well-preserved tracts of tropical dry forest. Nonetheless, little biological information is available for this area. In 1997 we initiated a series of studies aimed at supporting the conservation of the Zimatan region. Here we present floristic data based on 8,063 original botanical collections. The list includes 1,384 vascular plant species, distributed among 668 genera and 144 families. These collections make of the Zimatan region one of the most comprehensively collected areas and most diverse on the Mexican Pacific coast, along with the Chamela Biological Station in Jalisco State.

Corn Fields

Twenty five species and seven genera of micorrhizal arbuscular fungi (AMF) are reported for the region of Nizanda, Oaxaca, Mexico. To this end, soil samples were taken randomly, during the rainy and the dry seasons, in corn fields, secondary vegetation areas, as well as in primary tropical dry forest. Spores were isolated, identified and propagation pots were set. The family Glomeraceae accounted for 44% of the species, followed by Acaulosporaceae (24%) and Gigasporaceae (20%). In the corn fields 13 species were found, 24 in secondary vegetation, and 12 in the tropical dry forest. Among these, Glomus dussi, G. verruculosum, Pacispora scintillans and Scutellospora erythropa are new records for Mexico. G. constrictum was encountered only in the corn fields, whereas Acaulospora delicata, A. foveata, A. mellea, A. scrobiculata, Entrophospora infrequens, Gigaspora decipiens, Glomus claroideum, G. fulvum and G. geosporum occurred in the three environments. No species were restricted to the tropical dry forest.

Abstract Spondias tuberosa Arr., a fructiferous tree endemic to the northeast Brazilian tropical dry forest called Caatinga, accounts for numerous benefits for its ecosystem as well as for the dwellers of the Caatinga. The tree serves as feed for pollinators and dispersers as well as fodder for domestic ruminants, and is a source of additional income for local smallholders and their families. Despite its vantages, it is facing several man-made and natural threats, and it is suspected that S. tuberosa could become extinct. Literature review suggests that S. tuberosa suffers a reduced regeneration leading to population decrease. At this juncture S. tuberosa cannot be considered threatened according to the International Union for Conservation of Nature Red List Categories and Criteria, as it has not yet been assessed and hampered generative regeneration is not considered in the IUCN assessment. The combination of threats, however, may have already caused an extinction debt for S. tuberosa. Due to the observed decline in tree density, a thorough assessment of the S. tuberosa population is recommended, as well as a threat assessment throughout the entire Caatinga.
