A Novel Interaction: The thin stripe hermit Crab, Clibanarius vittatus, kills the Florida crown conch, Melongena corona, for its shell

A Novel Interaction: The thin stripe hermit Crab, Clibanarius vittatus, kills the Florida crown conch, Melongena corona, for its shell.

Abstract/Description
The hermit crab Clibanarius vittatus kills Melongena corona solely to acquire a better fitting shell. This finding is contrary to previous studies, which found that hermit crabs of other species cannot kill gastropods or, in most instances, remove freshly dead gastropods from their shells. This interaction cannot be classified as predation because Melongena tissue was never consumed. Clibanarius killed Melongena only when by doing so they could trade up to a better fitting shell. It cannot be...
Show moreThe hermit crab Clibanarius vittatus kills Melongena corona solely to acquire a better fitting shell. This finding is contrary to previous studies, which found that hermit crabs of other species cannot kill gastropods or, in most instances, remove freshly dead gastropods from their shells. This interaction cannot be classified as predation because Melongena tissue was never consumed. Clibanarius killed Melongena only when by doing so they could trade up to a better fitting shell. It cannot be classified as competition because there is no opportunity for Melongena to gain from the interaction. Therefore the term “lethal eviction” is hereby proposed for this interaction. The ability to kill a gastropod to obtain a superior shell gives Clibanarius vittatus an evolutionary advantage over other hermit crab species. It is not known if the outcome of this interaction is widespread where both species occur or if it is confined to the study area.

Factors Influencing the Distribution and Abundance of Sphaeroma terebrans in Florida’s Red Mangroves
Title
Factors Influencing the Distribution and Abundance of Sphaeroma terebrans in Florida’s Red Mangroves.
Creator
Huff, Sarah, Devlin, Donna, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
In Palm Beach County, S. terebrans burrows into grounded roots and trunks of R. mangle causing collapse. This is contrary to previous studies suggesting this species burrows only into free-hanging roots. Nutrients and C. virginica cover may affect S. terebrans abundance and distribution. Surveys show burrowing significantly varies among sites, but not between free-hanging and grounded roots. Nutrients vary by site, but neither N nor P was correlated with burrowing. Nutrient treated roots...
Show moreIn Palm Beach County, S. terebrans burrows into grounded roots and trunks of R. mangle causing collapse. This is contrary to previous studies suggesting this species burrows only into free-hanging roots. Nutrients and C. virginica cover may affect S. terebrans abundance and distribution. Surveys show burrowing significantly varies among sites, but not between free-hanging and grounded roots. Nutrients vary by site, but neither N nor P was correlated with burrowing. Nutrient treated roots showed no colonization pattern associated with N or P. Lignin varied among sites, but didn’t affect burrowing. Finally, C. virginica limited colonization in the portion of R. mangle tissue it covered. The location of C. virginica on the seaward/landward side was not predictive of burrowing. R. mangle height and leaves were not negatively affected by cover treatment or burrowing. Results highlight the need for additional research to determine the influence of environmental factors on this species interaction.

Postglacial expansion of Rhizophora Mangle l. In the Caribbean Sea and Florida
Title
Postglacial expansion of Rhizophora Mangle l. In the Caribbean Sea and Florida.
Creator
Kennedy, John Paul, Devlin, Donna, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
The Last Glacial Maximum (LGM) was a period of massive range contraction for numerous taxa, including the water-dispersed mangrove species, Rhizophora mangle L. Following the LGM, R. mangle expanded poleward via propagule transport by ocean currents. In this study, we use microsatellite loci to characterize the genetic structure of nine R. mangle populations and compare potential expansion pathways that resulted in the colonization of the Florida peninsula and Caribbean islands.

Show moreThe Last Glacial Maximum (LGM) was a period of massive range contraction for numerous taxa, including the water-dispersed mangrove species, Rhizophora mangle L. Following the LGM, R. mangle expanded poleward via propagule transport by ocean currents. In this study, we use microsatellite loci to characterize the genetic structure of nine R. mangle populations and compare potential expansion pathways that resulted in the colonization of the Florida peninsula and Caribbean islands. Results show comparatively greater genetic connectivity between the Caribbean mainland and Florida, a similar pattern between West Africa and Caribbean islands, and substantial admixture on the island of San Salvador, the Bahamas. We conclude that Florida and Caribbean island R. mangle populations were likely recolonized via different expansion pathways. Estimates of recent migration rates are low and populations are structured into three regions (Caribbean mainland, Caribbean islands, Florida). These findings provide insight for future management and conservation initiatives.
