| Summary: | 1992a). Previous biological research on anchialine caves has allochthonous sources are the open water cenotes and the along many tropical karstic and volcanic coastlines (Iliffe anchialine cave ecosystems in the Yucatan Peninsula, Quintana and Caribbean continue. are partially or totally submerged by stratified fresh and been limited to taxonomic and biogeographic investigations on Carbon and nitrogen stable isotopes were used to investigate cave ecosystem is supported by two allochthonous organic community. the lines of evidence for the 13carbon data, 15 contributor. Conceptual models for carbon and nitrogen cycling among the biotic and abiotic components of the data imply that nitrification is the chemoautolithotrophic discriminate food sources in these caves and to trace their ecosystem were constructed from the data. Suspension feeding ecosystem. Stable carbon and nitrogen isotopes were used to first detailed ecological investigation of an anchialine for niche partitioning is the first reported for any cave herein classified according to feeding type. This evidence marine waters and are prominent geological features found nitrogen data and morphological analysis all converge to the overlying jungle soil, while environmental and stable isotope prove fundamental to protecting this sensitive and economically questions regarding organic carbon and nitrogen cycling in Roo, Mexico. Anchialine caves are subterranean passages that same conclusions. These ideas offer a new paradigm for selective and species specific feeding behavior and are significant resource as development in the Yucatan Peninsula sources and possibly one chemoautolithotrophic source. The the biogeochemical and ecological processes that govern the troglobitic (cave limited) fauna, but fundamental these systems remain unexplored. This thesis represents the throughout the Caribbean region. This understanding may troglobitic fauna occupying the same niche exhibited understanding how this ecosystem operates both locally and utilization by the troglobites. The isotope data suggest the |
