POPULATION LIMITATIONS OF THE FLORIDA APPLE SNAIL (POMACEA PALUDOSA)
Title
POPULATION LIMITATIONS OF THE FLORIDA APPLE SNAIL (POMACEA PALUDOSA).
Creator
Drumheller, Danielle, Dorn, Nathan, Florida Atlantic University, Department of Biological Sciences, Charles E. Schmidt College of Science
Abstract/Description
In this thesis I examined factors limiting population success of apple snails (Pomacea spp.) in Florida wetlands. First, I examined effects of summertime hydropattern in replicated wetlands on reproduction and juvenile growth. Annual reproductive effort of Florida apple snails (Pomacea paludosa) and the invasive apple snail P. maculata under was not affected by deeper water in the summer. When juvenile P. paludosa were forced to grow in reportedly favorable and relatively deeper summertime...
Show moreIn this thesis I examined factors limiting population success of apple snails (Pomacea spp.) in Florida wetlands. First, I examined effects of summertime hydropattern in replicated wetlands on reproduction and juvenile growth. Annual reproductive effort of Florida apple snails (Pomacea paludosa) and the invasive apple snail P. maculata under was not affected by deeper water in the summer. When juvenile P. paludosa were forced to grow in reportedly favorable and relatively deeper summertime depths survival was high between treatments and growth was unaffected. In the other chapter I examined interactions between the two snails with a series of observations and experiments. I examined historical data on the assemblages and found that P. paludosa were locally extinguished in one of the wetlands within six years of invasion by P. maculata. Two field experiments gave conflicting results about the importance of interspecific inhibition of P. paludosa by the invasive snail, but in either case resource reduction could not be demonstrated. Lab exposure to P. maculata chemical cues strongly inhibited P. paludosa growth, although P. paludosa did not behaviorally avoid mucus of P. maculata. In mesocosms Pomacea paludosa growth was reduced with increasing exposure to adult P. maculata waterborne cues, and the results suggest that contact with mucus at a low exposure may even have a greater inhibiting effect. This interspecific direct chemical growth inhibition was novel for gastropods, but could be more generally important, and its potential impacts to P. paludosa populations should be explored further.

Discrimination of chemical signals from gastropods by hermit crabs
Title
Discrimination of chemical signals from gastropods by hermit crabs.
Creator
Gonsalves, Deirdre C., Florida Atlantic University, Brooks, W. Randy
Abstract/Description
Some species of hermit crabs can locate chemically predation sites where snails are consumed and subsequently obtain their shells. This study addressed four questions: (1) Is chemotaxis to snail odors prevalent among hermit crabs? (2) Do members of hermit crab lineages respond similarly to common snail odors? (3) Do hermit crabs respond more acutely to snails whose shells they most frequently occupy? and (4) Does phylogeny of snails influence responses by hermit crabs? Two sets of congeners ...
Show moreSome species of hermit crabs can locate chemically predation sites where snails are consumed and subsequently obtain their shells. This study addressed four questions: (1) Is chemotaxis to snail odors prevalent among hermit crabs? (2) Do members of hermit crab lineages respond similarly to common snail odors? (3) Do hermit crabs respond more acutely to snails whose shells they most frequently occupy? and (4) Does phylogeny of snails influence responses by hermit crabs? Two sets of congeners (Clibanarius vittatuslC. tricolor and Dardanus venosuslD. fucosus) in the family Diogenidae, and three congeners (Pagurus pollicaris, P. longicarpus, and P. annulipes) in the family Paguridae were tested. Fifteen species of snails from 11 families served as test odors. Hermit crab response was measured by the fondling display, where one hermit crab investigates the shell of a neighboring crab. The diogenids discriminated odors more readily than did the pagurids. Correlations between responses and shells most frequently occupied existed for C. vittatus and D. venosus. Clibanarius tricolor was the only crab to respond to confamilial test odors.
