Marine Biodiversity in the Caribbean: Regional Estimates and Distribution Patterns
The state of knowledge of marine biodiversity is analyzed based on the geographic distribution of georeferenced species records and regional taxonomic lists and it is found that the currently accepted classification of marine ecoregions of the Caribbean did not apply for the benthic distributions of five relatively well known taxonomic groups.
Viability of Ascaris and other helminth genera non larval eggs in different conditions of temperature, lime (pH) and humidity.
Results showed that there is a combination of conditions (temperature, pH and humidity) that is optimal for inactivation, and Ascaris, Toxocara and Taenia, in that order, were the most resistant, while the most sensitive were Trichuris and Hymenolepis.
The Caprellidea (Crustacea: Peracarida: Amphipoda) from the Gulf of Mexico with a description of a new species of Paracaprella
A new species of caprellid amphipod of the genus Paracaprella is described and illustrated in detail from coral rubble samples from the Arrecife Tuxpan/Lobos Protected Natural Area, off Veracruz State, Mexico, WSW Gulf of Mexico.
Regional diversity of amphipoda in the Caribbean Sea.
The order Amphipoda is one of the most diverse within Peracarids, and comprises 6950 described marine species, but areas of higher diversity seem to be concentrated along the Mexican Caribbean, Cuba and the Northern coast of South America (Venezuela-Colombia).
A new species of commensal amphipod (Amphipoda: Gammaridea: Leucothoidae) from Veracruz Coral Reef System, SW Gulf of Mexico
A new species of commensal amphipod of the genus Leucothoe (Leucothoidae) is described from the Veracruz coral reef system, Veracruz, in the SW Gulf of Mexico. The specimens were collected from the…
Peracarid crustaceans from three inlets in the southwestern Gulf of Mexico: new records and range extensions
Four new Gulf of Mexico records and nine geographic range extensions of peracarid crustaceans within the Gulf are presented for the southwestern Gulf of Mexico. The new records were obtained from…
Leucothoe Laurensi, A New Species Of Leucothoid Amphipod From Cuban Waters (Crustacea: Amphipoda: Leucothoidae)
Assessment of biodiversity in Chilean cattle using the distribution of major histocompatibility complex class II BoLA-DRB3 allele.
The phylogenetic tree showed that Red Angus and Black Angus cattle were in the same clade, crossbreeds were close related to their parent breeds, and Holstein cattle from Chile were closely related to Holenstein cattle in Japan.
Large-Scale Spatial Distribution Patterns of Gastropod Assemblages in Rocky Shores
This work represents the first effort to sample gastropod biodiversity on rocky shores using a standardized protocol across a wide scale and will generate more work to build global databases allowing for large-scale diversity comparisons of rocky intertidal assemblages.
A new sponge-inhabiting leptostracan species of the genus Nebalia (Crustacea: Phyllocarida: Leptostraca) from the Veracruz Coral Reef System, Gulf of Mexico
A new species of Leptostraca, Nebalia villalobosi, is described from the Veracruz Coral Reef System, SW Gulf of Mexico, which is the first record of a leaptostracan associated with the sponge Ircinia fistularis.
