Interactions Between Individuals and Sex Rather Than Morphological Traits Drive Intraspecific Dung Removal in Two Dung Beetle Species

چکیده

Dung beetle functional ecology has traditionally focused on studying the relation between traits and ecosystem functions in multispecies assemblages, often ignoring contribution of behavioral interactions trait variability within species. Here we focus factors that affect dung removal at an intraspecific level two horned species with dimorphic males ( Onthophagus taurus verticicornis ). By setting treatments for each single individuals (one female, F; one major male, M; minor m) or pairs (MF, mF, MM, mm, FF), examined effect morphological (head, pronotum, leg, horn), sex, individuals. Our results showed depended more sex than underlying traits, whose effects were negligible. Single females generally removed males, which suggests are effective males. In both species, least female FF) high efficiency, but did not perform differently from sum (M + F, m f, F F). This additive effect: (or females) join their efforts when they together. The only (MM mm) less M m), indicates a mutual inhibition male morphs performed similarly as same amount dung. Despite our limited to suggest beetles might be influenced by rather traits.

Temporal Segregation between Dung-Inhabiting Beetle and Fly Species

The coexistence of ecologically similar species (i.e. species utilizing the same resource) is a major topic in ecology. Communities are assembled either through the biotic interactions of ecologically similar species, e.g. competition, or by the abiotic separation of species along gradients of environmental conditions. Here, we investigated the temporal segregation, succession and seasonality o...

Assessing the Importance of Intraspecific Variability in Dung Beetle Functional Traits.

Functional diversity indices are used to facilitate a mechanistic understanding of many theoretical and applied questions in current ecological research. The use of mean trait values in functional indices assumes that traits are robust, in that greater variability exists between than within species. While the assertion of robust traits has been explored in plants, there exists little informatio...

Dung 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...

A '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...

Greenhouse gas emissions from dung pats vary with dung beetle species and with assemblage composition

Cattle farming is a major source of greenhouse gases (GHGs). Recent research suggests that GHG fluxes from dung pats could be affected by biotic interactions involving dung beetles. Whether and how these effects vary among beetle species and with assemblage composition is yet to be established. To examine the link between GHGs and different dung beetle species assemblages, we used a closed cham...
