Evidence of fresh oil from the BP/Deepwater Horizon Mississippi Canyon-252 (MC-252) well was found in the northern Gulf of Mexico up to 1 year and 10 months after it was capped on 15 July 2010. Offshore and coastal samples collected after capping displayed ratios of biomarkers matching those of MC-252 crude oil. Pre- and post-capping samples were compared. Little weathering had occurred, based on the abundance of low-molecular-weight (LMW) n-alkanes and polycyclic aromatic hydrocarbons (PAHs) in the post-capping samples. The occurrence of fresh oil in offshore waters and coastal areas suggest that the MC-252 well continued to leak hydrocarbons into the Gulf of Mexico at least until 22 May 2012, the end of this study period.

Solenogastres is a group of mollusks with evolutionary and ecological importance. Nevertheless, their diversity is underestimated and knowledge about the distribution of the approximately 300 formally described species is limited. Factors that contribute to this include their small size and frequent misidentification by non-specialists.

Background: Within the subfamily Leptomysinae (fam. Mysidae), the tribe Mysidopsini has five here acknowledged genera and 74 extant species. It embraces the genera with six species from the coasts of the NW-Atlantic (Narragansett Bay to Florida), the Caribbean and Gulf of Mexico; with two species from the SW-Atlantic off Brazilian shores and from the Pacific coast of Ecuador; with three species from the Caribbean, Gulf of California and southern California; with ten species from the Atlantic coasts of the USA to Brazil, Caribbean, Gulf of Mexico and E-Pacific from California to Panama; and, finally, the globally occurring .

Objectives: This study aimed to evaluate the working and health conditions faced by divers in small-scale fisheries in the Midriff Islands Region of the Gulf of California, Mexico.
Methods: The study was conducted in five fishing communities. A semi-structured questionnaire was administered to 113 fishers (~15% of the commercial divers in the region).

(Theobald) (Hemiptera: Aphididae), commonly called the sorghum aphid, is an invasive pest of sorghum () (L.) in North America. It was first observed in 2013 along the Gulf Coastal Plains ecoregion of Texas, Louisiana (USA), and Mexico, where it quickly established itself as an economically important pest within a few years.

When a species is introduced in a new location, it is common for it to establish itself when it finds favorable conditions in the receptor community with regard to interspecific interactions with native species. The azooxanthellate corals coccinea and are invasive species introduced in the Caribbean Sea, the Gulf of Mexico, and the Brazilian Southwest Atlantic. They are successful competitors for space, have multiple reproductive modes, and have high larval dispersion and recruitment, but studies on food and trophic relationships of the genus are still scarce.
