Impact of the 2011 Tohoku Earthquake on the species diversity of rocky intertidal sessile assemblages. [PDF]

Ecol Evol
The 2011 Tohoku Earthquake in Japan had a serious impact on rocky intertidal community. We assessed alpha diversity, beta diversity, and their effect sizes during the pre‐earthquake period (2003–2010) and post‐earthquake period (2011–2019) at local scale and regional scale.

Local ecological knowledge (LEK) suggests overfishing and sequential depletion of Peruvian coastal groundfish

Marine and Coastal Fisheries, Volume 15, Issue 6, December 2023., 2023
Abstract Objective Fish populations targeted by recreational and artisanal fisheries remain largely unassessed in low‐ and middle‐income countries. This generally results in a lack of regulatory action from government agencies, thus aggravating the risk of overfishing.

Danger, risk and anti‐predator behavior in the life history of long‐distance migratory sandpipers

Journal of Avian Biology, Volume 2022, Issue 6, June 2022., 2022
Two recent and independent studies both estimate substantially lower survival rates of semipalmated Calidris pusilla than of western C. mauri sandpipers, consistent with the pronounced multi‐decade population decline of the former. Migratory danger has climbed steadily for both these long‐distance migrants since the mid‐1970s as the number of peregrine

Characterization and production potential of carotenes in Peruvian strains of Dunaliella salina Teodoresco

Journal of the World Aquaculture Society, Volume 53, Issue 3, Page 765-780, June 2022., 2022
Abstract Chlorophyte microalgae Dunaliella are halophilic flagellated cells; they can resist high salinities, producing β‐carotene to balance osmotic stress. This pigment has important antioxidant properties for biotechnology, the prevention of tissue aging, the efficiency of the immune system, and sun protection against UV‐B rays.

Trophic interactions and metal transfer in marine ecosystems driven by the Peruvian scallop Argopecten purpuratus aquaculture

Journal of the World Aquaculture Society, Volume 53, Issue 2, Page 452-474, April 2022., 2022
Abstract This study investigates the trophic interactions and As and Cd transfer along seven marine ecosystems in Peru. Five of these ecosystems are driven by aquaculture of the Peruvian scallop Argopecten purpuratus. A southward increased gradient of δ15N was observed among the three examined regions along the Peruvian coast.
