Snakes can learn to discriminate profitable from less-manageable prey. Naive garter snakes, Thamnophis melanogaster, attacked both the carrion-eating leech Erpobdellapunctata and the blood-sucking leech Haementeria officinalis even though naive snakes respond less to the odor of H. officinalis. The latter thwarted...

Many flowering plants attract insect pollinators by releasing odorant molecules that mimic an insect s natural food sources or potential egg-laying sites. Plants pollinated by flies or beetles that normally feed on or lay their eggs in dung or carrion sometimes use foulsmelling compounds to attract these insects. 

Not all floral scents consist of fragrant volatiles. Unpleasant odors associated with dung, carrion, urine, rotting fungi, and decaying cabbage and onion have been found in abiotic mimicry in many plant families such as Araceae, Aristolochiaceae, Orchidaceae, and Apocynaceae.103 Several saprophagous insects are attracted to these flowers and act as selective pollinators. 

Chemically, 1. a. are often alcohols or carboxylic acids and esters derived from alkenes or alkadienes but also terpenoid or heterocyclic compounds may have I. a. activity. In many cases the ratio of ciVfrani-isomers or, in the case of chiral compounds, the enantiomer ratio often plays a decisive role for the effectiveness of La. Many other substances occurring in the environment also have an attracting effect on insects, especially those associated with the search for food examples the typical odors of certain plants (e.g., arum), flower and fruit odors, emanations from animals and humans [CO2, lactic acid, (-)-(/ )-l-octen-3-ol] or carrion. 

We hypothesized that compounds that attract brown tree snakes could be those that are considered major components of the odor of carrion. These include cadaverine, di-methylamine, dimethyl disulfide, dimethyl sulfide, ethanethiol, trimethylamine, and putre-scine, (Eskin, Henderson Townsen, 1971 Stager, 1964). For testing, we chose odor concentrations that were easily detectable, but not overpowering, to the human nose. 

Carrion, which may be detected at least in part by odor cues, possesses considerable attraction for carnivores, whether as a...
