Euphausiids (Crustacea: Euphausiacea) from a hotspot of marine biodiversity, Isla del Coco, Costa Rica, Eastern Tropical Pacific
Eufáusidos (Crustacea: Euphausiacea) de un punto caliente de biodiversidad marina, Isla del Coco, Costa Rica, Pacífico Tropical Oriental
Euphausiids have been well studied in several regions of the Pacific Ocean; however, there is less information regarding euphausiids in Costa Rican waters. We analyzed euphausiid specimens collected around Isla del Coco ...
NC10 bacteria in marine oxygen minimum zones
Bacteria of the NC10 phylum link anaerobic methane oxidation to nitrite denitrification through a unique O2-producing intra-aerobic methanotrophy pathway. A niche for NC10 in the pelagic ocean has not been confirmed. We ...
Mercury levels in muscle tissue of four common elasmobranch species from the Pacific coast of Costa Rica, Central America
Mercury (Hg) is a non-essential and toxic element that is ubiquitous in the marine environment and biomagnifies through food webs. Given the high trophic position of many elasmobranch species, it is important to quantify ...
