Ecotoxicity of losartan potassium in aquatic organisms of different trophic levels
(2021-10-01)
The intensive use of the antihypertensive losartan potassium (LOS) has culminated in its high occurrence in aquatic environments. However, insufficient studies had investigated its effects in non-target organisms. In this ...

Trophic level and overlap of sea lion (Zalophus californianus) in the Gulf of California, Mexico
(2008)
Stable isotope and scat analyses were used in concert to determine trophic level and dietary overlap among California sea lions from different rookeries in the Gula of California. Isotopic analysis of the fur of sea lion ...
The trophic role of lutjanid fish and impacts of their fisheries in two ecosystems in the Gulf of Mexico
(Journal of Fish Biology, 1998)
The trophic role of snappers was evaluated on the continental shelves of the south-western Gulf of Mexico and the Yucatan in the south-eastern Gulf of Mexico. Mass-balanced, steady-state trophic models of the two ecosystems ...
Energy flow and network analysis of Terminos Lagoon, SW Gulf of Mexico
(Journal of Fish Biology, 1998)
The food web in Terminos Lagoon, south-western Gulf of Mexico was dominated by the detrital pathway, with benthic invertebrates playing a significant role in transferring energy from detritus to higher trophic levels. The ...
First approach to the trophic ecology and diet of the rainbow runner, elagatis bipinnulata (Quoy & Gaimard, 1825) (Pisces: Arangidae), in the central Colombian Caribbean
The rainbow runner (Elagatis bipinnulata) scores high in trophic level (4.24) but it is not a voracious fish (Q/B = 10.8). Its diet
is dominated by the dwarf herring (Jenkinsia lamprotaenia), eats more in the dry season, ...
