ResumenEl tayra (Eira barbara) y el ocelote (Leopardus pardalis) son dos especies que se encuentran catalogadas en peligro de extinción. En este trabajo presentamos nuevos registros de ambas especies en la región litoral centro del estado de Yucatán, México. Nuestras observaciones se basan en registros obtenidos mediante cámaras trampa colocadas en fragmentos de vegetación secundaria de selva baja caducifolia (SBC) con cierto grado de perturbación. Obtuvimos dos registros de tayra, en uno de ellos se aprecian dos individuos y seis fotografías de ocelote. Estos registros muestran la importancia de los manchones de sbc como potenciales refugios, corredores biológicos o sitios de paso para las especies silvestres.Palabras clave: Cámaras-trampa, Carnívora, nuevos registros, Yucatán.AbstractThe tayra (Eira barbara) and ocelot (Leopardus pardalis) are species that are cataloged in danger of extinction. In this work we present new records of both species in the central coastal region of Yucatan state, Mexico. Our observations are based on records using camera traps, placed in fragments of secondary vegetation in tropical dry forest (TDF) with some degree of disturbance. We obtained two records of tayra, one of them shows two individuals, in addition to six photographs of ocelot. These records denote the importance of tdf patches as potential shelters, biological corridors or wildlife passage sites.Key words: Camera-trapping, Carnivore, new records, Yucatan.

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.

In this paper we revise the species of Sicarius (Araneae: Sicariidae) from the Brazilian Caatinga, the largest tropical dry forest nucleus in the world. We redescribe, designate a neotype and provide new records for Sicarius tropicus (Mello- Leitão, 1936), the only species previously known from the region, and describe three new species: S. cariri n. sp., S. diadorim n. sp. and S. ornatus n. sp. We report high intraspecific variation in the genitalic morphology of these species, especially in females. We also provide anecdotal observations on natural history and behavior of these species, including diet, mating behavior and clutch size. We include an identification key for Brazilian Caatinga species of Sicarius.

Resumen: Antecedentes y Objetivos: Actualmente, se reconocen 21 especies adscritas al género Rhytidhysteron. En México sólo se ha reportado Rhytidhysteron rufulum. El género se caracteriza por sus histerotecios naviculares a apoteciales, el borde es estriado o liso; los colores del epitecio varían de anaranjado-rojizo, amarillo, verde a negros y las ascosporas presentan tres septos longitudinales. El objetivo del presente estudio es realizar una revisión taxonómica del género Rhytidhysteron en México, basada en caracteres macro y micromorfológicos.Métodos: Se realizaron diez exploraciones entre 2017 y 2019 en diversas regiones de México. Además, se revisaron los especímenes depositados en la colección de hongos del herbario ENCB. Los ejemplares fueron estudiados, descritos y determinados de acuerdo con las técnicas tradicionales en micología. Resultados clave: Se revisaron 381 especímenes pertenecientes al género Rhytidhysteron, de los cuales se determinaron cuatro especies: Rhytidhysteron neohysterinum, una nueva especie para la ciencia, R. neorufulum y R. thailandicum que son nuevos registros para el país, y R. rufulum previamente citado.Conclusiones: El género Rhytidhysteron tiene una alta diversidad de especies en México. La mayoría de los especímenes se han encontrado sobre ramas en descomposición, principalmente en géneros de la familia Fabaceae en bosque tropical caducifolio, lo que podría sugerir que este grupo de plantas representa el microhábitat al que las especies de Rhytidhysteron se han adaptado.Palabras clave: distribución, histerotecio, Hysteriales, nueva especie, taxonomía. Abstract:  Background and Aims: Currently, 21 species associated with the genus Rhytidhysteron are recognized. In Mexico, only Rhytidhysteron rufulum has been reported. The genus is characterized by its navicular to apotecial histerothecia, the margin is striate or smooth; the colours of the epithecium vary from orange-reddish, yellow, green to black and its ascospores present three longitudinal septa. The objective of this study is to carry out a taxonomic review of the genus Rhytidhysteron in Mexico, based on macro- and micromorphological characters.Methods: Ten exploration trips were realized between 2017 to 2019 in several regions of Mexico. In addition, the specimens deposited in the fungus collection of the ENCB herbarium were reviewed. The specimens were studied, described and determined according to traditional mycological techniques.Key results: 381 specimens belonging to the genus Rhytidhysteron were reviewed, of which four species were determined: R. neohysterinum, a new species for science, R. neorufulum and R. thailandicum, new records for the country, and the previously cited R. rufulum.Conclusions: The genus Rhytidhysteron has a high diversity of species in Mexico. Most specimens have been found on decomposing branches, mainly of genera of the Fabaceae family in tropical dry forest, which suggest that this group of plants represent the microhabitat to which Rhytidhysteron species have best adapted.Key words: distribution, Hysteriales, hysterothecium, new species, taxonomy.

Abstract The Chamela Biological Station (ChBS) is located in the Pacific Coast of Mexico in the State of Jalisco. This represents one of the core areas of the Chamela-Cuixmala Biosphere Reserve, characterized by one of the most threatened ecosystems, the tropical dry forest. Although accumulated knowledge of biological diversity, only few studies have been focused on ectoparasites or ectodytes associated with mammals, only 23 arthropod taxa had been recorded. In order to increase knowledge about arthropods associated with Mexican mammals, the objective of this work was to record the richness of arthropods (mites, ticks, lice, and fleas) associated with small and medium-sized mammals in the ChBS. A total of 81 hosts belonging to four orders, six families and nine species were captured. From these hosts, 4,946 arthropods were recovered: 4,007 mites, 673 ticks, 230 lice, and 36 fleas. Among medium-sized mammals, Nasua narica (L.) and Didelphis virginiana Kerr showed the highest levels of richness, with six arthropod taxa; among rodents, Heteromys pictus (Thomas) had the highest number of associated species (five). Within the 22 arthropod taxa registered in the present work, 12 represent new records for the reserve, and 3 represent new records for Mexico. With this study, the arthropod fauna associated with mammals in the ChBS has been raised to 38 taxa. In terms of biological conservation, knowledge of the species that inhabit natural reserves must be a priority, since this represents the baseline for species protected, not only in Mexico but around the world.

Occurrence Records

We provide species lists and geographical occurrence records of the beetle family Passalidae for three subregions of the department of Sucre, northern Colombia. The sampling localities are lowland environments with typical tropical dry forest vegetation. We selected 15 sampling sites and examined decomposing trunks. We record seven species, four genera, and two tribes of Passalidae. The most abundant species were Passalus punctiger Lepeletier & Serville, 1825, P. interstitialis Eschscholtz, 1829, and P. interruptus (Linnaeus, 1758). We also provide new records for Passalus punctatostriatus Percheron, 1835, Paxillus leachi MacLeay, 1819, and Popilius marginatus (Percheron, 1835) in the department of Sucre. Veturius aspina Kuwert, 1898 was present only in the localities with well-preserved forests. Finally, the species number recorded in this study is low compared to other inventories in Neotropical regions.

Se estudia la caracterización limnológica de 30 lagunas del bosque tropical seco de Costa Rica y Nicaragua durante 2010-11. Se aislaron gémulas de esponjas de agua dulce en cuatro de las localidades. Se registraron dos nuevas citas de esponjas para Nicaragua, Radiospongilla cerebellata (Bowerbank, 1863) y Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974). En Costa Rica también se registró esta última y se recolectaron ejemplares de Radiospongilla crateriformis (Potts, 1882). En otra laguna de Costa Rica, se recolectó una larva neuróptero (Insecta) de la familia Sisyridae asociada a las esponjas: Sisyra apicalis Banks, 1908. Por otro lado, hemos podido recolectar gémulas incrustadas en el tubo de alojamiento del oligoqueto Aulophorus vagus Leidy, 1880 (Annelida: Oligochaeta: Naididae), que también supone la primera cita para Costa Rica y Nicaragua. The characterization of 30 temporary ponds was done in the tropical dry forest of Costa Rica and Nicaragua, in 2010-2011. Gemmules of sponges were isolated in four of the studied sites. Two new records were set for Nicaragua, Radiospongilla cerebellata (Bowerbank, 1863) and Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974). In Costa Rica, the last ones was also recorded as well as specimens of Radiospongilla crateriformis (Potts, 1882) were collected. In another pond of Costa Rica, larva of Neuroptera (Insecta) belonging to family Sisyridae, commonly associated to sponges, was collected: Sisyra apicalis Banks, 1908. In addition, we have been able to collect embedded gemmules in the housing tube of the annelid Aulophorus vagus Leidy, 1880 (Annelida: Oligochaeta: Naididae). This species is also here reported for the first time in Costa Rica and Nicaragua.

Natural Reserve

Fauna in Tropical Dry Forest (TDF) is highly dependent on water availability due to a marked seasonality in precipitation. There are few studies addressing carnivore’s ecology and the role of seasonality of TDF in Neotropics. We used scent-station and camera trapping to assess seasonal changes in occurrence and habitat use probability with seasonality. We also described activity patterns and collected fresh scats to describe diet for small sized carnivore species in a TDF fragment in the Colombian Caribbean region. We present information regarding: Cerdocyon thous, Leopardus pardalis, and Procyon spp. The analysis showed a significantly higher occurrence probability during the dry season for the three species, and no differences in the detection probability between seasons. The diet of C. thous included 24 different food items; for L. pardalis it was composed of seven items, and finally, 25 food items were identified in the diet of Procyon spp. We found that the three species presented activity patterns corresponding with previous studies. Finally, our results reflect that these species are probably making more/larger habitat use during the dry season than in the wet season, because the area has permanent water ponds by which limited resources (such as water and food) are available almost constantly in this natural reserve.
