Winter and Summer Bird Communities of Twin Cays , Belize
نویسنده
چکیده
Avian species richness and abundance were studied in order to characterize the bird fauna of Twin Cays, Belize. Auditory and visual surveys were conducted for both migratory and resident species during winter and summer seasons. The Mangrove Yellow Warbler was the most common bird species on the islands in both seasons, with an estimated mean density of 13.4 birdsha during the winter and 10.9 birdsha in the summer. The importance of mangrove habitats to a diversity of migratory passerines and resident breeding birds along the Mesoamerican Barrier Reef is supported with 56 species of 20 families recorded from the islands.

Mangrove roots in the well-protected channels and ponds among dense mangrove stands provide very similar habitats for sponges in the Twin Cays and Pelican Cays and harbor extraordinarily dense and diverse sponge communities in both locations. The species of sponges are very different, however, possibly because of an important difference in context: the Twin Cays mangrove roots are embedded in p...

Gnathostomulida, a phylum of microscopic, interstitial marine worms, are well represented in detritus-rich sandy sediments that are usually found between coral reefs, seagrasses and mangroves. Of 25 species encountered in more than 100 sediment samples collected in southern Belize between 1974 and 2004, 18 species were found in the vicinity of Twin Cays.
متن کاملCaribbean placozoan phylogeography.
We here address placozoan distribution and phylogeography in five locations in the Caribbean Sea. We performed a coarse-resolution presence/absence survey of placozoans in Belize, Bermuda, Grenada, Jamaica, and Panama and a fine-resolution study of the distribution of placozoans in Twin Cays, Belize. Placozoans were recovered in every country sampled. Animals were sequenced at the mitochondrial...
متن کاملPhylogenetic Diversity of Diazotrophs along an Experimental Nutrient Gradient in Mangrove Sediments
The diversity of diazotrophs was studied in the sediment of mangrove forests (Twin Cays, Belize) subjected to a long-term fertilization with nitrogen and phosphorus. Terminal Restriction Fragment Length Polymorphism (TRFLP) and cloning of PCR-amplified nifH genes were combined via in silico analysis to assign clones to TRFLP-nifH phylotypes, as well as to characterize the occurrence of phylotyp...

A combination of transplant experiments and provision of recruitment surfaces has been initiated to determine the degree to which differences in sponge diversity and species composition at two Twin Cays sites, Hidden Creek and Sponge Haven, reflect differences in abiotic factors, ecological interactions, and recruitment history. This report contains the first stages of this project. The Hidden ...
