En este estudio analizamos los patrones espaciales y temporales de la cobertura y uso del suelo de la Reserva de la Biosfera Selva El Ocote (REBISO) y sus impactos en la conectividad funcional del paisaje de acuerdo con 2 especies indicadoras, la pava cojolita (Penelope purpurascens) y el pajuil (Penelopina nigra). Se emplearon mapas de cobertura del suelo de 2005 y 2019 elaborados con imágenes satelitales de alta resolución. La matriz predominante en ambos años fue la vegetación secundaria arbustiva (37.7%), en la que estuvieron inmersos bosques maduros (3.6%) y secundarios (35.8%), además de otras coberturas no forestales (22.9%). En este período se deforestaron 753 ha (0.7%) de bosques maduros y secundarios, y se regeneraron 226 ha (0.2%). Entre 2005 y 2019 se incrementó la fragmentación del área, pero el contagio (CONTAG) fue de 61.6%, lo que muestra una conectividad estructural intermedia de la vegetación forestal. La conectividad funcional para ambas especies se concentró en la zona núcleo I de la REBISO y para la pava cojolita, también hacia el sur de esta área. Se señalan las áreas críticas para mantener y mejorar la conectividad funcional de estas especies al interior de esta área protegida.

El sureste de México ha sufrido una gran transformación del paisaje, en parte por la presencia de sistemas de aprovechamiento forestal. Describimos comunidades de avifauna en monocultivos de eucalipto y hule en Huimanguillo, Tabasco, y evaluamos la influencia estructural de estos monocultivos en las aves. Se establecieron 118 puntos de conteo de aves (6 réplicas) y parcelas para evaluar la vegetación. En los 708 puntos se observaron 4,699 individuos de 148 especies de aves; la mayor riqueza y abundancia se presentó en eucalipto. El Anosim mostró diferencias significativas entre hule y eucalipto. El Simper indicó que Psilorhinus morio y Eupsittula nana aportaron mayores porcentajes de disimilitud. La estructura de vegetación difirió estadísticamente entre sitios, particularmente las variables arbóreas en plantaciones con respecto a sus matrices circundantes. Los modelos lineales generalizados (GLM) indicaron que la estructura de sotobosque y el tipo de plantación influyen sobre la diversidad de aves. Los monocultivos de eucalipto en Huimanguillo sustentan una comunidad de aves más rica que la del hule. El eucalipto parece formar parte fundamental del hábitat invernal para aves migratorias en esta región. El sotobosque en sistemas agroforestales es un elemento esencial para las aves en paisajes dominados por actividades antrópicas.

Impacts caused to freshwater reservoirs by human activities have increased in tropical and subtropical regions in the last decades. We studied the effects of land use on the physicochemical properties of water and their effects on larval Odonata diversity in a subtropical lagoon. During 1 year, physicochemical variables were measured, and Odonata larvae were collected in 8 sites (4 in the urbane zone and 4 in the more conserved rural zone) with different land uses that cover the entire periphery of the lagoon. Physicochemically, no clustering of samples from urban and rural zones or by site was observed, rather clustering reflected temporal patterns. A total of 28 species were found and some of them showed a differential distribution between both zones, and between the 8 sites and collectings. The highest diversity was recorded in the rural zone. The site with domestic waste discharges had the lowest diversity and it showed high concentrations of nitrates and ammonium. We conclude that the effect of land use in this lagoon is still incipient on Odonata diversity. The diversion and treatment of urban waters and proper land management are recommended to ensure the maintenance of Odonata diversity.

El murciélago mastín azteca (Molossus aztecus) es una especie que habita desde México hasta Brasil. A pesar de su amplia distribución, sorprende la aparente escasez de registros en Norteamérica. Aquí revisamos la información disponible en bases de datos públicas para conocer la distribución espacio-temporal de sus registros y estimamos su distribución potencial actual para facilitar esfuerzos de colecta futuros. Después de la selección de datos con criterios que disminuyen la incertidumbre en la identidad y la localización geográfica, obtuvimos 411 registros de este murciélago, los cuales se concentran en México (207), Nicaragua (77) y Guatemala (74). La mayor cantidad de registros proviene de meses lluviosos como julio (85) y agosto (84), y de los años 1966 (74) y 1969 (70). En las últimas 2 décadas, los registros en bases de datos son nulos, lo que podría deberse al rezago en la digitalización de ejemplares ya colectados. La distribución potencial indica condiciones altamente idóneas para M. aztecus en la vertiente del Pacífico, en donde aún hay zonas poco exploradas por mastozoólogos. Para mejorar el conocimiento de su distribución, es necesario incluir otros métodos de muestreo y fomentar la digitalización de colecciones científicas.

Private conservation areas (PCA) are a complementary resource that can be used to favor the conservation of mammals in tropical regions of the world. However, their reduced extent can exert a differential influence on the behavior of the species present, and ultimately affect their coexistence. We investigated the daily activity patterns of canopy mammals during the rainy season of 2016 in a 100 ha PCA in tropical forest. To record activity, 11 camera traps were set up in trees at 15 m above ground level. Sciurus deppei was the only diurnal mammal recorded. Potos flavus was more active around midnight, while Caluromys derbianus and Coendou mexicanus were active before (21:00 to 23:00 h) and after midnight (01:00 to 04:00 h). Tamandua mexicana and Didelphis marsupialis were active throughout the night. The nocturnal mammals showed great overlap in their hours of activity. Overall, there was no difference in activity patterns of canopy mammals in this small PCA compared to those reported in larger protected natural areas. The highest number of records occurred in the tallest trees located in the highest and best-conserved parts of the study area, suggesting the importance of forested PCA to the conservation of canopy mammals.

El género Ganoderma se ha estudiado escasamente en el sureste de México. El objetivo del presente estudio fue contribuir al conocimiento de la diversidad de especies de Ganoderma para México y Tabasco. Se analizaron 247 ejemplares de herbario provenientes de 16 municipios del estado. Se observaron las características macro y micromorfológicas de los basidiomas. Las observaciones microscópicas se hicieron en KOH al 5% y la determinación taxonómica se realizó mediante diversas claves especializadas. Se identificaron y describieron 21 especies de Ganoderma, de las cuales 17 corresponden al subgénero Ganoderma y 4 al subgénero Elfvingia. G. carnosum, G. dunense, G. lipsiense, G. multipileum, G. multiplicatum, G. neojaponicum, G. orbiforme, G. philippii, G. sichuanense,G. stipitatum y G. subresinosum son registros nuevos para México. Dichas especies también son reportes nuevos para Tabasco, incluyendo a G. australe, G. oerstedii, G. oregonense, G. sessiliforme, G. tsugae y G. zonatum. Se presenta una clave dicotómica para las especies identificadas. El inventario refleja la diversidad de Ganoderma en México y el trópico tabasqueño.

The hairy fruit-eating bat Artibeus hirsutus is endemic to Mexico and is considered a rare species. The little biological and ecological data on this species does not provide much information on its conservation status. The objective of this work was to evaluate the population structure and reproductive activity of a colony of A. hirsutus in west-central Mexico. We visited 12 times Isla Grande Atoyac, Jalisco. The individuals were captured inside the 2 caves with bucket traps or by hand directly from the cave roof, and with mist nets placed within the vegetation. We marked 77 individuals (67 adults, 5 juveniles, and 5 newborns), of which 34 were recaptured. The pooled recapture rate was 58.47%, and it increased from March to October and decreased in November and December. The minimum-number-alive value was higher in February (34) and lower in October (5), with an average of 21.1 individuals. Among the adult bats, 25.3% were males and 74.6% were females, with an overall female-biased sex ratio of 1:3.2. Sexual dimorphism was observed, with a significantly greater forearm length in females (55.7 mm) than males (54.4 mm). The study population showed a seasonal bimodal polyestry reproductive pattern.

Species of Lobophora (Dictyotales) are distributed throughout the sub-tropical and tropical seas worldwide. Recent analyses have revealed high species diversity in regions previously presumed to host only a single species, such as the Bismarck Sea, Eastern Pacific, Western Atlantic, Mediterranean Sea, and Greater Caribbean. Here, samples from Veracruz and Quintana Roo, Mexico, were collected, and 2 genetic markers (cox3 and psbA) were sequenced. The results confirmed the presence of L. dispersa and L. variegata. Lobophora dispersa is recorded for the first time on the Mexican coast. The distribution of its cox3 haplotypes shows genetic differentiation within the Greater Caribbean and Gulf of Mexico, possibly indicating limited dispersal and isolation by distance. Lobophora variegata exhibits lower genetic variability compared to L. dispersa, but its haplotypes did not show any obvious pattern. Lobophora declerckii, previously reported in the “Anegada de Afuera” reef, Veracruz, was not found, possibly due to its affinity to subtidal depths. Morphologically, L. dispersa and L. variegata align with previous descriptions, although we observed more variation in thallus cell thickness in L. dispersa. However, relying solely on morphological characters is insufficient to confidently identify the species, necessitating further sampling to determine the species diversity in Mexico.
叶蝗属的种类分布于世界各地的亚热带和热带海域。最近的分析显示，在以前被认为只有单一物种的地区，如俾斯麦海、东太平洋、西大西洋、地中海和大加勒比海，物种多样性很高。本文收集了墨西哥韦拉克鲁斯州和金塔纳罗奥州的样品，并对2个遗传标记(cox3和psbA)进行了测序。结果证实了分散L.和杂色L.的存在。在墨西哥海岸首次记录到弥散的Lobophora。其cox3单倍型的分布在大加勒比海和墨西哥湾显示出遗传分化，可能表明有限的分散和距离隔离。与散叶叶相比，杂色叶叶的遗传变异性较低，但其单倍型没有明显的规律。以前在韦拉克鲁斯的“Anegada de Afuera”珊瑚礁中报道的loophora declerckii没有被发现，可能是由于它对潮下深度的亲和力。在形态上，分散L.和杂色L.与先前的描述一致，尽管我们观察到分散L.的菌体细胞厚度差异更大。然而，仅仅依靠形态特征不足以自信地识别物种，需要进一步采样以确定墨西哥的物种多样性。
