The development of a Bayesian network model that examines the trade-offs between the conservation value of the landscape for a range of taxa (flora, mammals, birds and herpetofauna) and its primary production value under alternative land uses is described. The model emphasises structural diversity of vegetation and ecosystem productivity as key drivers of both biodiversity and agricultural production. Simple scenarios, used to examine the influence of different land uses on multiple components of biodiversity and agricultural productivity, demonstrated the potential for the analysis of the trade-offs associated with alternative landscape designs. The potential of the model, as a planning or policy development tool for land management agencies or regional Natural Resource Management bodies, at multiple scales, is identified.

Being part of an open signalling system, odour cues can be exploited by 'eavesdropping' predators that hunt by smell, making association with odour a high-risk behaviour for prey. Here, we show that adult great barred frogs (Mixophes fasciolatus) are highly attracted to odour cues of conspecifics and those of sympatric striped marsh frogs (Limnodynastes peronii). This attraction decreased significantly with the addition of odours of a scent-hunting predator, the red-bellied black snake (Pseudechis porphyriacus), indicating that frogs perceived predation risks from associating with frog odours. Male frogs, however, maintained some attraction to unfamiliar conspecific scents even with predator odours present, suggesting that they perceived benefits of odour communication despite the risk. Our results indicate that adult frogs can identify species and individuals from their odours and assess the associated predation risk, revealing a complexity in olfactory communication previously unknown in adult anurans.
