... as a baseline for future long term monitoring. Seasonal trends, environmental effects and disturbances on haul-out numbers were investigated for seals at this site. The haul-out site was occupied by both Australian A. pusillus doriferus , and New Zealand A. forsteri , fur seals, with A. pusillus doriferus...

... This paper reviews the factors involved in the decline, both inter- and intra-specific, of Australian frogs from both disturbed and apparently pristine habitats. Despite a lack of published accounts and an absence of long term population studies, a variety of causes were identified. Habitat...

..., in which case each species will respond directly to environmental factors; 2) dependent upon a set of biological interactions among species; or 3) of a combination of both environmental and biological factors. Our second point is that climate extremes will drive substantial change beyond any changes...

... Surveys of microbat communities in several regions of Western Australia have revealed a diversity-productivity model of community structure in which co-occurring species occupy different foraging niches, but environmental factors influence turnover in species composition across landscapes...

... (environmental) factors. The latter include history and geography while poor dispersal capability is typically important amongst the former. Oceanic islands, seamounts and specialised deep-sea habitats, such as hot vents and cold seeps, often have significant numbers of narrow-range taxa. Low levels of narrow...

... activity and awareness, rather than the actual rate of strandings. However, annual fluctuations in the number of stranding reports are probably also due in part to variations in environmental factors. ...

... plant productivity; animals then do not have to rely on proximate factors to predict conditions nine months in advance. External influences that re-align reproduction to match a phase-shift in environmental conditions have to either adjust the period of the biological clock, or else induce a phase-shift...

.... But it relied on doubtful survey techniques. Since the Mabo Case and the Coronation Hill Inquiry, Aboriginal cultural values have become decisive factors in environmental assessment. A value matrix model, incorporating a science-culture axis, is proposed. “That a thing may have any value in exchange, two...

... Few quantitative data exist on the anecdotal observations of many researchers which apparently indicate a global decline of Amphibia in both disturbed and seemingly pristine habitats. This study was initiated to determine the responses of frogs to local, human-induced environmental stress. Frogs...

... This chapter discusses the nutritional factors that determine the densities of arboreal folivores - principally the koala, greater glider, common ringtail possum and common brushtail possum - in eucalypt forests. We examine the subject on two scales. The first is a broad approach that relies...
