Ricinuleids are one of the least investigated groups of Arachnida. In particular, knowledge of their ultrastructure is poor. Observations of the distal tarsomeres of ricinuleids show differences in their shape and equipment ...

La fragmentación de hábitats debida a la deforestación origina profundos cambios en los procesos ecológicos; uno de estos cambios es el efecto de borde, el cual consiste en la generación de microclimas variables y de ...
Amphibians are greatly affected by diversity loss and recent declines in amphibian populations are well documented. One of the proposed causes of such declines, UV-B radiation, has been reported to induce lethal and ...

El objetivo del trabajo fue evaluar la variabilidad morfológica y el crecimiento corporal de 4 poblaciones del cocodrilo de pantano (Crocodylus moreletii) que se encuentran en la Unidad de Manejo para la Conservación de ...
Seasonal and environmentally induced variation in the type and frequency of leaf trichomes of Wigandia urens (Ruiz & Pavon) Kunth (Hydrophyllaceae) was studied. Depending on the microsite, W. urens plants had smooth leaves ...
We document variation among 13 populations of distinct species of the lizard genus Xenosaurus in four key reproductive traits: minimum size at maturity, litter size, size at birth, and relative clutch mass (RCM). Despite ...

1 Gaps in the forest canopy allow establishment of many understorey species. As gaps close, their: demographic behaviour is affected by changing environmental conditions. A demographic analysis of Primula vulgaris populations ...

To understand the population dynamics of a species, it is necessary to document the way in which its demographic behaviour varies through space and time. Anthropogenic disturbance, such as shifting cultivation, is an ...

Several studies have proposed a group of morpho-functional traits as determinants of the ecological strategy of species. Among these, four morpho-functional traits are considered to be relevant in determining a plant's ...
Se analiza la estructura y composición florística de 13 potreros establecidos en áreas originalmente cubiertas por selva alta perennifolia, en la Sierra de Los Tuxtlas, Veracruz. En ellos es común encontrar árboles aislados ...
We updated the floristic checklist of the Nizanda region, Isthmus of Tehuantepec (southern Mexico), characterized the occurring plant communities based on dominant species, and described the region's flora according to ...

We evaluated the Collembola communities at 3 different heights on epiphytic moss. The study was carried out in an Abies religiosa forest, in the locality of San Rafael in the State of Mexico, Mexico. Collembola inhabiting ...
