چکیده

Predators may communicate silently through olfactory compounds in urine, faeces, and glandular secretions. Infochemicals and metabolites consist of both non-polar (short-chain fatty acids and their metabolites) and polar (sulphur-based and associated carrier proteins) compounds that interact to provide multiple layers of information to conspecifics (Brennan 2009). Information within urine can communicate territorial markers (Gorman & Trowbridge 1989; Brennan 2009), oestrous (Sankar & Archunan 2008), nutritional status (how recently a predator has fed; Gelperin 2008), and a time-stamp of the predator’s void (Wyatt 2003) Degradation of these molecules over time will reduce the level of information available in the chemical compound (Wyatt 2003).

Novel use for a predator scent: preliminary data suggest that wombats avoid recolonising collapsed burrows following application of dingo scent

Southern hairy-nosed wombats (Lasiorhinus latifrons) are fossorial marsupials that live in large burrow systems where their digging behaviour brings them into conflict with agriculture. In the absence of any available control options, non-selective culling is the primary mode of wombat management. This approach is contentious and has unknown implications for long-term wombat conservation. Preda...

Familiarity Breeds Contempt: Kangaroos Persistently Avoid Areas with Experimentally Deployed Dingo Scents

BACKGROUND Whether or not animals habituate to repeated exposure to predator scents may depend upon whether there are predators associated with the cues. Understanding the contexts of habituation is theoretically important and has profound implication for the application of predator-based herbivore deterrents. We repeatedly exposed a mixed mob of macropod marsupials to olfactory scents (urine, ...

Are dingoes a trophic regulator in arid Australia? A comparison of mammal communities on either side of the dingo fenceaec_2022

The direct and indirect interactions that large mammalian carnivores have with other species can have far-reaching effects on ecosystems. In recent years there has been growing interest in the role that Australia’s largest terrestrial predator, the dingo, may have in structuring ecosystems. In this study we investigate the effect of dingo exclusion on mammal communities, by comparing mammal ass...

Tools and Technology An In Situ Vertebrate Bioassay Helps Identify Potential Matrices for a Predator-Based Synthetic Management Tool

To assist management and conservation needs, researchers have called for active kairomones to be elucidated and synthesized directly from animal exudates. However, the existing literature does not provide guidance on how to initiate this complex process. To our knowledge, composite synthetic predator scents that incorporate multiple compounds to accurately mimic the natural signal have not been...
