The Foraging Ecology And Habitat Selection Of The Yellow-Plumed Honeyeater (Lichenostomus Ornatus) At Dryandra Woodland, Western Australia, Kellie Wilson Jan 1997

The Foraging Ecology And Habitat Selection Of The Yellow-Plumed Honeyeater (Lichenostomus Ornatus) At Dryandra Woodland, Western Australia, Kellie Wilson

Theses : Honours

The foraging ecology and habitat selection of the Yellow-plumed Honeyeater was examined using observations and vegetation surveys at Dryandra Woodland, Western Australia. Foraging ecology data was collected over three seasons (autumn, winter and spring) in 1997 at three sites within Dryandra. Habitat selection studies involved 156 sites being surveyed for the presence or absence of the Yellow-plumed Honeyeater. The vegetation characteristics of the site were measured. Yellow-plumed Honeyeaters foraged by gleaning foliage most of the time. Bark and aerial foraging were also common. Birds clearly selected for tree height, preferring to forage on larger (older) trees which may be because …


The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges Jan 1997

The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges

Theses : Honours

Conventional agricultural practices (tillage, extensive application of synthetic fertilisers and biocides) exert substantial disturbance on soil ecosystems, consequently causing severe land degradation through loss of soil organic matter. These practices also place significant pressure on the soil inhabitants. However, permaculture systems practice non-tillage and extensive mulching. These non-tillage practices reduce the amount of perturbation on the litter invertebrates and encourage their abundances. The aims of this study were to describe the above-ground mesofaunal communities in the mulch layer of selected urban permaculture systems in the Perth Metropolitan area. This included determining the faunal abundance and diversity. Four permaculture sites were …
