La fragmentation del bosque mesofilo de montana y pa-trones de uso del suelo en la region oeste de Xalapa, Veracruz, Mexico.

This study showed that, although species richness remains relatively constant across a landscape, local richness alpha diversity changes notably over even relatively short periods of time. This could be a characteristic of moderately disturbed landscapes where the assemblages are very flexible. Co-authors View all Claudia E.

As for abundance, the two types of forest are the most variable, and the pasture is the most stable. The temporal and spatial distribution of the 18 species registered in this study were notably diverse.

During three intensive sampling periods, and using the same methodology, the accumulated number of species alpha diversity was 29 species, whereas the historical record gamma diversity, including samplings from several researchers was 50 species.

Este trabajo pone de manifiesto que gonzzalo la riqueza de especies del paisaje se mantiene relativamente constante, la riqueza a nivel local diversidad alfa cambia notablemente aun en lapsos cortos de tiempo. The general objective of this study was to determine the stability in time of copronecrophagous beetles Scarabaeinae assemblages in a set of habitats representing a gradient of anthropogenic transformation in a mountainous tropical landscape.

Usted necesita tener Javascript activado para poder verla. The species accumulation curves reached a clear asymptote in 6 of the 10 possible cases and at the level of the entire hhalffter Fig.

Protected areas, whether they are national parks or biosphere reserves, are currently established to conserve a space that is rich in living beings, preferably a type of community with the least degree of anthropogenic interference possible.

The changes that occurred between samplings affected the less abundant species in the cloud forest and in the pasture. Habitat associations and community analysis of south Texas dung beetles Coleoptera: One way of learning about these dynamics and the level of variation in an assemblage is to evaluate whether its members species continue to be present over time and whether their abundance remains constant Connell and SousaMagurran and Philip As we have indicated, these variations could be a reflection of the flow of Scarabaeinae between the habitats of this landscape that are shaded by trees.

Quintero and Roslin cite references detailing the recovery of other groups of animals in the Manaus experiment, providing a whole new perspective on what can happen to species richness a few halfvter after the tropical landscape is altered by people, as long as the matrix is “friendly.

An ecological and evolutive approach. The diversity and abundance of epiphytes were lower than those for the sites mentioned above.

To detect those guilds for which frequency of appearance differed by sampling year, we subdivided the contingency tables and reanalyzed the data with the same test Zar Species diversity and habitat fragmentation:
