Spatial variation in the distribution and abundance of submersed macrophytes in the Mary River, a subtropical Australian river, was examined at 29 sites on four occasions (116 samples) over a one year period. Thirteen submersed macrophyte taxa representing seven families were recorded during the study period. Submersed macrophyte cover was generally patchy and mean quadrat cover per sample was ...

Although functional trait variability is increasingly used in community ecology, the scale- and size-dependent aspects of trait variation are usually disregarded. Here we quantified the spatial structure of shoot height, branch length, root/shoot ratio and leaf number in a macrophyte species Potamogeton maackianus, and then disentangled the environmental and ontogenetic effects on these traits....

Two opposing hypotheses concerning determinants of mangabey (Cercocebus albigena) ranging patterns have been advocated. One hypothesis suggests that ranging patterns of mangabeys are largely a response to fruit availability, while the other hypothesis advocates that concerns of fruit availability are supplemented or overridden by concerns of fecal contamination and that the risk of parasite inf...
