We evaluated the status of coarse woody debris (CWD, fallen wood) on floodplains of the southern Murray-Darling basin of southeastern Australia. The floodplains are dominated floristically by the river red gum Eucalyptus camaldulensis. Aerial survey

Habitat clearance generally produces fragmented landscapes. A major consequence is the creation of large amounts of new ‘edge habitat’, often of a kind not previously existing, such as abrupt forest- agricultural land interfaces. Much work from a

Three species of sexually dichromatic, insectivorous birds (Golden Whistler, Pachycephala pectoralis; Rufous Whistler, Pa. rufiventris; Rose Robin, Petroica rosea) employ a characteristic foraging manoeuvre (snatching or sally-striking) disproportion

The bird community structure of an undisturbed forest (Olinda State Forest) east of Melbourne, Victoria, varied greatly among the winters of 1993, 1994 and 1995. Increases in the total density of all diurnally active species were as much as 66% betwe

Communities of forest and woodland birds are usually studied intensively at only one or a few locations. This provides a perspective that perhaps emphasizes local phenomena at the expense of placing local dynamics in the context of processes operatin

There has been debate as to whether the composition of avifaunas is determined primarily by responses of species to the floristic composition of habitats or to the structural features of habitats (viz. physiognomy). Some evidence suggests that the ef

Habitat ordinations were performed on 37 sites in forests and woodlands along a latitudinal transect that spanned over 250 km in central Victoria. Australia. Multivariate analyses of these data by using nonmetric. multidimensional scaling (AIDS) were

There are several ways to approach the question of how distributions of species are determined, including field experimentation and computer or mathematical modelling. If large numbers of species are to be considered simultaneously, modelling is the
