We expect as the habitat is less transformed, the assemblage is more stable over time, which could be observed through fewer changes in species richness and composition over time.

This scenario leads us to think about high levels of species turnover, which may reflect assemblages that are unstable in time.
Eurysternus mexicanus was found in the same habitat type during T2.

From forest to pasture: Related articles in Web of Science Google Scholar. If we look at species composition, we find that there are big differences between the two sampling periods for all of the habitats, with the exception of the pasture. This ahlffter assumes that the protected areas are relatively stable, with no changes in their biota when they are protected from external influences.
Six species, Ateuchus illaesumEurysternus mexicanus, O. The changes that occurred between samplings affected the less abundant species in the cloud forest and in the pasture.

Studies carried out using a single indicator group such as this study can provide a first approximation, but we know that different groups respond differently to fragmentation and change Pineda et al. Frog, bat, and dung beetle diversity in the cloud forest and coffee agroeco-systems of Veracruz, Mexico. The highest richness 13 species was recorded during the second sampling T2 of the traditional shaded coffee plantation, whereas the lowest richness three species was recorded in the first sampling T1 of the pasture.
Comparative analysis of reproductive and nesting behavior in several species of Eurysternus Dalman Coleoptera: This species was the most abundant at T1 in the secondary forest, yet was absent from this habitat at T2. In the survey Howden and Howden11 species were found, 9 of which had been collected in ; D. At each site, every month during the first sampling period T1we set up a transect with 10 pitfall traps spaced 25 m apart and baited with alternating human excrement and decomposing squid.
An interesting question is: We recognize that our results are based on the study of a single indicator group on one landscape, but even so, it is possible to make a recommendation regarding conservation policies. Rapid turnover and edge effects in dung beetle assemblages Scarabaeidae at a Bolivian neotropical forest-savana ecotone. This has resulted in landscapes that are highly fragmented and where biological diversity faces constant and varied disturbances.
Gonzalo Halffter Madrid, Spain, is a national emeritus lecturer at the Institute of Ecology in Xalapa Mexico and a renowned expert in the study of biodiversity and the management of the natural environment.
We are not referring to the other species given that they are typical of habitats where we did not sample during this study. Sign In or Create an Account. Biogeographical and ecological factors affecting the altitudinal variation of mountainous communities of coprophagous beetles Coleoptera: Copronecrophagous beetles of the Scarabaeinae subfamily Coleoptera: The diversity and abundance of epiphytes were lower than those for the sites mentioned above.
View large Download slide. These data suggest that, except in pastures, the Scarabaeinae assemblages are very unstable over time. The nesting behavior of dung beetles Scarabaeinae.
At T2, Coprophanaeus telamon went from being a moderately abundant species to being co-dominant, and we recorded three species in low abundance that were not caught at T1. What are the number and identity of the species that remain constant in habitats with different degrees of disturbance?
Biology Conservation, 10 2: Dr Halffter has had a long and prolific scientific career, above all in the field of zoology research specifically in the field of entomology, about which he is considered a preeminent authority. Scarabaeinae G Halffter Biogeographia 15 1, We have been addressing these questions with a strategy Halffter based on four points: The second, halfftdr canopy is m high ginzalo is comprised of cultivated species belonging to IngaCitrusMusaPerseaand Psidium.
The assemblages belong to cloud forests the original vegetation typesecondary forests, traditional shaded coffee plantations, commercial shaded coffee plantations, and a cattle pasture.
Biology International Special Issue. Altitudinal variation of dung beetle Scarabaeidae: We recognize that halvfter differences between T1 and T2 are not the same for all habitats varying between 4 and 11 yrwhich could introduce a source of potentially confounding effect. Avaliacaodoimpactodafragmentacaoda floresta sobre Scarabaeinae Coleoptera: Areas that were originally occupied by TMCFs are now covered with shaded coffee plantations, cattle pastures, and other crop sites Challenger
