In general, faunal diversity increases with forest age; therefore, we predict that ant species richness in secondary forests will increase during succession and species composition will vary among different stages of ...

Effects of terrigenous sedimentation are considered a serious threat to Puerto Rico’s coral reefs. This study assesses: 1) the composition of sediments accumulating at reef sites on the southwestern shelf of Puerto Rico; ...

Observations of humpback whales (position, number and presence of calf) were obtained from a commercial whale-watching vessel during January to March 1995 to 1997 along the northwestern coast of Puerto Rico. These data ...

In the wider Caribbean, the Nassau grouper (Epinephelus striatus) is considered a commercially important fish. However, its former abundance has declined precipitously in many areas due to overfishing. In Mona Island, ...

Surveys of Sistema Los Chorros (815m length) and Sistema Vientos (600 m) represent the first cave maps from southern Puerto Rico published in the last quarter century. These are the largest caves known in that area. They ...

A study was conducted on the industrial area waters of Guayanilla Bay to determine the potential for microbial utilization of toxic compounds such as fluorene, naphthalene, phenanthrene, phenol and pentachlorophenol (PCP) ...

Coelothrix irregularis (Harv.) Børgesen, until recently a member of the Rhodymeniaceae, has had several familial assignments within the Rhodymeniales. While suggested by some that the genus belonged in the Champiaceae on ...

Plants have theoretically multiple alternatives for preventing self pollination and consequently the effect of inbreeding, such as sequential flowering, dichogamy and self–incompatibility to name a few. We investigated the ...

The objective of this study was to provide evidence supporting the contention that sediment transport (bedload) is a major environmental factor controlling the distribution of shallow-water gorgonian species. Gorgonians ...
