Spatial Patterns of Movement of Dung Beetle Species in a Tropical Forest Suggest a New Trap Spacing for Dung Beetle Biodiversity Studies
A primary goal of community ecologists is to understand the processes underlying the spatiotemporal patterns of species distribution. Understanding the dispersal process is of great interest in ecology because it is related to several mechanisms driving community structure. We investigated the mobility of dung beetles using mark-release-recapture technique, and tested the usefulness of the curr...
متن کاملA 'metaphising' dung beetle.
You may have seen the film Microcosmos, produced in 1996 by the French biologists Claude Nuridsany and Marie Perrenou. It does not star humans, but much smaller creatures, mostly insects. The filmmakers’ magnifying camera transposes the viewer into the world of these organisms. For me, Microcosmos is not an ordinary naturalist documentary; it is an exercise in metaphysics. One sequence in the f...
متن کاملDung beetle movements at two spatial scales
To understand the dynamics of spatially structured populations, we need to know the level of movements at different spatial scales. This paper reports on Aphodius dung beetle movements at two scales: movements between dung pats within pastures, and movements between pastures. First, I test an assumption common to many recent models of spatially structured populations – that the probability of a...
متن کاملRespiratory airflow in a wingless dung beetle.
The sealed subelytral cavity of many flightless beetle species is widely acknowledged to be an adaptation to water saving in arid-habitat species. However, this hypothesis relies on the acceptance of two largely untested assumptions: (i) that the movement of respiratory gases is unidirectional from anterior to posterior and (ii) that the coordinated action of the spiracles directs this flow. We...
متن کاملVariegated tropical landscapes conserve diverse dung beetle communities
BACKGROUND Conserving biodiversity in tropical landscapes is a major challenge to scientists and conservationists. Current rates of deforestation, fragmentation, and land use intensification are producing variegated landscapes with undetermined values for the conservation of biological communities and ecosystem functioning. Here, we investigate the importance of tropical variegated landscapes t...
