Currently, the tropical dry forest found on rock formations originating from volcanic activity are the best preserved, but also the least studied in the State of Veracruz, Mexico. We recorded 104 families comprising 394 genera and 666 species and subspecies of vascular plants. These latter taxa were classified in the following growth form categories: 88 trees, 126 shrubs, 342 herbs, 80 vines and 30 epiphytes. The richest families, considering the recorded species, were Fabaceae, Poaceae, Asteraceae and Euphorbiaceae. The presence of a rich succulent component in the tropical dry forest flora was noticeable. It is conformed by 204 species and subspecies, corresponding to 30.4% of the total for such vascular taxa recorded in the study area. The highest ichness of succulent species was found in the most diverse families, such as Euphorbiaceae, Orchidaceae, Cactaceae, and Bromeliaceae.

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.

Otatea, with 12 described species, is the second most diverse genus in the subtribe Guaduinae. Eleven species of Otatea occur in Mexico, of which 10 are endemic. The Mexican Otatea species grow in tropical dry forest, the ecotone between tropical dry forest and oak forest, cloud forest, humid oak-pine forest, and xerophilous scrubs. Here, we describe the synflorescence and flowers of Otatea nayeeri and O. transvolcanica, based on newly collected specimens and review of existing herbarium material. We present a key based on the flowering characters of the Mexican Otatea species, and provide expanded morphological descriptions and illustrations of O. nayeeri and O. transvolcanica. Otatea nayeeri and O. transvolcanica do not exhibit the gregarious monocarpic flowering pattern that has been recorded for other Otatea species. A flowering individual of O. transvolcanica was observed being visited by a Lasioglossum (Dialictus) sp. (Halictidae) bee. This is the first record for Otatea being visited by bees. The geographical distribution of O. nayeeri is extended northwards to the state of Durango in Mexico.

Based on the review of floristic and taxonomic literature, as well as on the examination of specimens housed at the herbaria of the Centro Regional del Bajío (IEB) and the Instituto de Biología (MEXU), we recorded 845 species, 352 genera and 100 families of trees for the state of Michoacán, Mexico. The largest numbers of species per family were recorded for Asteraceae (82), Fabaceae (74), Mimosaceae (67), Caesalpiniaceae (39) and Burseraceae (38), while at the genus level Bursera (37), Quercus (35), Lonchocarpus (19), Senna (18), and Acacia (16) are the most speciose. The genus Beiselia (Burseraceae) and 14 species (1.8 %) are strict endemics to the state. A total of 28 families (28%) and 210 genera (60%) are represented in the state only by one tree species each. The most important vegetation types according to their species richness are tropical deciduous forest (593, 70.2%), coniferous forest (336, 39.8%) and oak forest (332, 39.3%). A high proportion (69.9%) of Michoacán’s tree species is located in 2-4 vegetation types; 173 species (21.5%) have been found just in one type, mainly in the tropical dry forest (87 species, 10.3%). The floristic richness of Michoacán is largely explained by its complex geologic history, its rugged physiography, its diverse climate, and its multiple vegetation types, as well as by its location at the confluence of the Holartic and Neotropical floristic kingdoms. Counties and species on which to focus conservation efforts for trees in the state are pinponted.

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.

A study on the patterns of richness, diversity and abundance of the Odonata from Santiago Dominguillo, Oaxaca is presented here. A total of 1601 specimens from six families, 26 genera and 50 species were obtained through monthly samplings of five days each. Libellulidae was the most diverse family (21 species), followed by Coenagrionidae (19), Gomphidae (4) and Calopterygidae (3). The Lestidae, Platystictidae and Aeshnidae families were the less diverse, with only one species each. Argia was the most speciose genus with 11 species, followed by Enallagma, Hetaerina, Erythrodiplax and Macrothemis with three species each and Phyllogomphoides, Brechmorhoga, Dythemis, Erythemis and Orthemis with two species each. The remaining 17 genera had one species each. Argia pipila Calvert, 1907 and Leptobasis vacillans Hagen in Selys, 1877 were recorded for the first time for the state of Oaxaca. We also analysed the temporal patterns of taxonomic and phylogenetic divergence for the Santiago Dominguillo Odonata assemblage: the Shannon diversity value throughout the year was 21.07 effective species, while the Simpson diversity was 13.17. In general, the monthly phylogenetic divergence was higher than expected for taxonomic distinctness, and lesser for average taxonomic distinctness. Monthly diversity, evenness and taxonomic divergence showed significant positive correlations (from moderate to strong) with monthly precipitation values. The analysis of our results, however, indicates that an increase in rainfall not only influences the temporal diversity of species, but also the identity of supraspecific taxa that constitute those temporal assemblages, i.e. there is an increase in temporal phylogenetic divergence.

La Selva

<p>La selva baja caducifolia es un ecosistema que está presentando grandes cambios. A pesar que a nivel global se han estudiado las fuerzas conductoras del cambio de uso de suelo, a escala local las dinámicas espacio-temporales son ampliamente desconocidas. El objetivo principal de este estudio fue identificar las fuerzas conductoras de los cambios de uso y coberturas del suelo en la selva baja caducifolia en dos municipios al Sur de México. Para alcanzar dicho objetivo fueron utilizadas imágenes satelitales y fotografías aéreas dentro de un SIG, para producir los mapas de uso y de coberturas del suelo para los años 1985, 1995 y 2006. Diferentes métodos estadísticos (cadenas de Markov, modelos lineales generalizados y análisis por regresión de árbol) fueron empleados para identificar las causas próximas y subyacentes de la deforestación, donde resalta la agricultura como la más importante de ellas. Las actividades agrícolas, principalmente la de autoconsumo están delimitadas espacialmente por las características topográficas del terreno. El incremento de las oportunidades de trabajo vinculadas con el sector turístico han resultado en el abandono de las actividades agropecuarias, favoreciendo al regeneración y recuperación del bosque. En México diferentes estudios han examinado las dinámicas locales de la deforestación y las fuerzas conductoras, sin embargo, este estudio considera tanto la escala espacial como la temporal fueron claves para identificar las causas subyacentes más importantes de la deforestación, la dinámicas a escala local y la comparación entre dos municipios vecinos.</p>

The Big Crested Mastiff Bat, Promops centralis (Thomas, 1915), is widely distributed from Mexico to South America but has yet to be reported in the state of Sinaloa, Mexico. We collected 122 acoustic recordings of P. centralis from tropical dry forest and agroecosystems in Sinaloa and Sonora for two years (2015 and 2016). We documented a new record for P. centralis outside the known distribution area in northwestern Mexico. Our results reveal that the current P. centralis distribution needs to be reevaluated.
