A new genus and species of Eusiridae (Crustacea, Amphipoda, Amphilochidea) from bathyal sediments off the southwestern Gulf of Mexico.

A new monotypic genus of eusirid amphipod, Pseudorhachotropis gen. nov., is described and illustrated from a male specimen collected from bathyal soft bottoms (2321 m depth) in the southern Gulf of Mexico.

Cadmium, copper and lead in macroalgae from the Veracruz Reef System, Gulf of Mexico: spatial distribution and rainy season variability.

This study focused on the spatial distribution of trace metals in the Veracruz Reef System in the Southern Gulf of Mexico, and its variability in the early (July) and late (September) rainy season of 2008, by analyzing the concentration of Cd, Cu and Pb in benthic macroalgae. Mean concentrations are lower (Pb 295 ± 347 ng g(-1), Cd 17.9 ± 15.

[Effects of hurricane "Pauline" (1997) on the fauna associated with the plant Eichhornia crassipes in Laguna Coyuca, South Pacific of Mexico].

Effects of hurricane "Pauline" (1997) on the fauna associated with the plant Eichhornia crassipes in Laguna Coyuca, South Pacific of Mexico. Reports on the effects of hurricanes on marine and coastal environments often deal with coral reefs, but little is known about their effect on the communities associated with the water hyacinth, Eichhornia crassipes. From January 1997 (pre-hurricane) through April 1998 (post-hurricane) we made montly collections of fauna in E.

[Does sea-grass biomass control the density of peracarids (Crustacea: Peracarida) in tropical lagoons?].

We analyzed the time-space variation of the peracarid crustaceans that inhabit seagrasses of the Alvarado Lagoon System, Veracruz, Gulf of Mexico. The organisms were collected from 108 samples in six sites with Ruppia maritima beds (December 1992 to November 1994). The assemblage was composed of 11 species.
