Response To Water

The salt marsh periwinkle, Littorina irrorata, exhibits a spatial refuge from predation by climbing the stems of Spartina alterniflora in order to avoid benthic predators. Salt marsh periwinkles have a broad geographic distribution, and for many species, responses to predators also varies with biogeography. This study sought to determine if the geographical location of the home marsh influenced the response of periwinkles (climbing height) to blue crab predator cues both via air and water. Snails from Louisiana (LA) climbed higher in general than those from North Carolina (NC), regardless of chemical cue. However, LA snails climbed 11 cm higher in the presence of waterborne predators than control snails with no cue, while NC snails only climbed five cm higher in the same comparisons. Airborne chemical cue tended to have snails climbing at intermediate heights. These responses were significantly enhanced when both populations of snails were housed together. Periwinkle response to predator cues was stronger in LA than NC, and so it is possible that the behavioral response of these snails to predators varies with biogeography of the home marsh. Also interestingly, the results of this study also suggest that cue delivery is probably occurring via mechanisms other than water, and potentially via airborne cues. Therefore, salt marsh periwinkles likely respond to numerous cues that initiate behavioral responses, including airborne cues, and these responses may vary by home-marsh geography.

Snake Predators

AbstractStudies of a limited number of species of fish in the superorder Ostariophysi have shown they they exhibit strong antipredator behaviour to conserved alarm substance in feces and in other byproducts from predatory fish that have consumed ostariophysans. Our experiments examined the ability of a previously untested ostariophysan to recognize chemical cues from two species of snake predators. In Experiment 1, shoals of golden shiners (Notemigonus chrysoleucas) exhibited strong shelter-seeking responses to water which contained waste byproducts from either a sympatric snake or an allopatric snake which had been fed golden shiners but not to a distilled water control. There was no difference in response to the sympatrie snake predator, northern water snakes (Nerodia sipedon), compared to the allopatric snake predator, black-bellied garter snakes (Thamnophis melanogaster). In Experiment 2, individual shiners exhibited vigourous dashing when presented with water which contained waste byproducts from N. sipedon fed golden shiners but exhibited a much weaker response to water which contained waste byproducts from N. sipedon fed green swordtails (Xiphophorus helleri, a non-ostariophysan) or to a water control. These results suggest that the alarm substance produced in the epidermis of the golden shiners is conserved in snake waste byproducts. Experiment 3 showed that there was little difference in shelter-seeking behaviour by shoals of shiners when presented with water in which N. sipedon had soaked, water in which T. melanogaster had soaked, or a distilled water control. Thus it appears that secretions from the skin of these predators may not be chemically labelled.

Myrophis Punctatus

The speckeld worm eel Myrophis punctatus lives in high-densities assemblages, and usually digs through, or lies on the substrate. These behaviours could lead to chemical marks on the substrate and could modulate the spatial distribution in this species. We tested the hypothesis that the spatial choice of the speckled worm eel is modulated by the presence of conspecific odour on the substrate. Here, we showed that the speckled worm eel avoids the substrate area containing the conspecific odour, indicating that this chemical cue modulates the eel's spatial decision. The eels clearly detected the conspecific's odour. This perception might indicate the presence of conspecifics into the substrate. Since the eels avoided an area containing conspecific odour, we suggest this may be a response that avoids the consequences of invading a resident-animal's territory.
