The Comparative Effectiveness of Rodents and Dung Beetles as Local Seed Dispersers in Mediterranean Oak Forests
The process of seed dispersal of many animal-dispersed plants is frequently mediated by a small set of biotic agents. However, the contribution that each of these dispersers makes to the overall recruitment may differ largely, with important ecological and management implications for the population viability and dynamics of the species implied in these interactions. In this paper, we compared t...
متن کاملrole of functional groups of dung beetles on secondary seed dispersal by removing sheep dung case study: shahrekord rangelands)
the present study was conducted to assess the effect of dung beetles on sheep dung removal and seed dispersal in semi steppe rangelands of shahrekord province with poor condition located in iran. therefore, the large (1 cm2) and small size (1 mm2) meshes were used and filled by sheep dung in six treatments. to evaluate the role of the insects in seeds translocation, three sizes of plastic beads...
متن کاملDung beetles use their dung ball as a mobile thermal refuge
At midday, surface temperatures in the desert often exceed 60°C. To be active at this time, animals need extraordinary behavioural or physiological adaptations. Desert ants, for instance, spend up to 75% of their foraging time cooling down on elevated thermal refuges such as grass stalks. Ball-rolling dung beetles work under similar thermal conditions in South African savannahs. After landing a...
متن کاملThamnophilidae (antbird) Molt Strategies in a Central Amazonian Rainforest
—Avian molt, or the regularly scheduled replacement of feathers, is an important life history event, particularly in central Amazonian rainforest birds for which a relatively high proportion of the annual cycle can be dedicated to this process. Here, we detail molt strategies of 18 antbird species (Thamnophilidae) based on 2,362 individuals captured from lowland tropical rainforest at the Biolo...
