The phylogenetic results imply an East Tethyan origin of the Scaridae and the recurrent evolution of excavating and scraping feeding modes, and a two‐phase model of parrotfish evolution to explain patterns of comparative diversity. Expand
Interspecific pollen transfer as a mechanism of competition: effect of Castilleja linariaefolia pollen on seed set of Ipomopsis aggregata
The results suggest that there is a priority effect; deposition of C. linariaefolia pollen on I. aggregata flowers results in competition, but only when C. Linariaefolium pollen is deposited first. Expand
Morphological and genetic species diversity in ostracods (Crustacea: Oligostraca) from Caribbean reefs
Using a morphological (shell shape and ornamentation) and molecular barcoding approach (28S rDNA), this work provides the first report of the biodiversity of ostracods in the mesophotic coral ecosystems of northeastern Caribbean. Expand
A new species of Pseudoleptochelia Lang, 1973 (Crustacea: Peracarida: Tanaidacea: Leptocheliidae) from the Northwest Atlantic with observations on the status of the genus.
Pseudoleptocheliajuliae n. sp. is described from Puerto Rican waters in depths from 1 to 28 m. The new species and P. fairgo from western Australia are the only members of the genus as defined inExpand
Population connectivity of the plating coral Agaricia lamarcki from southwest Puerto Rico
High population connectivity with subtle subpopulation structure among all sampling localities is estimated in the brooding Caribbean plate coral, Agaricia lamarcki. Expand
A new species of Litarachna (Acari, Hydrachnidia, Pontarachnidae) from a Caribbean mesophotic coral ecosystem
The new species was collected from nearly 70 m depth, the greatest depth from which pontarachnid mites have been found until now, and was found in association with the tube of the polychaete Sabellastarte magnifica at the shallow waters of north Puerto Rico. Expand
The oligochaetofauna of the Nipe soils in the Maricao State Forest, Puerto RicoThe 7th international symposium on earthworm ecology · Cardiff · Wales · 2002
Summary The oligochaetofauna of the Nipe soils of Puerto Rico was studied for the first time. Earthworm and soil samples were taken over a year at six different sites. Earthworms were hand sortedExpand
Saltipedis (Spinosaltipedis) puertoricensis, a new subgenus and species of apseudomorphan (Crustacea: Tanaidacea: Parapseudidae) from coastal waters off Culebra Island, Puerto Rico, with keys and
The new species is the fourth representative of the genus Saltipedis Guţu to be described from the western Atlantic and the new subgenus is distinguished by the presence of strongly developed accessory setae on the mandible between the base of the palp and the molar process. Expand
The earthworms of Baño de Oro, Luquillo experimental forest, Puerto Rico
The earthworm fauna of the four forest types at the Bano de Oro region of the Luquillo Experimental Forest was sampled over 6 months and the total species density and biomass showed no significant correlation to forest type or soil depth, but some species did show different distribution patterns according to certain soil properties.

Abundance and distribution of Pontodrilus litoralis in the shores of the Cabo Rojo Lighthouse, Puerto Rico
Abstract The structure and dynamics of the populations of the oligochaete Pontodrilus litoralis on the coasts near the Cabo Rojo Lighthouse in Puerto Rico were studied. Sampling was made at low tideExpand
