Characterization of cannibalism in early paralarvae of Patagonian red octopus, Enteroctopus megalocyathus (Gould, 1852), grown in a controlled environment

open access: yesJournal of the World Aquaculture Society, 2021
In the experimental mariculture of Patagonian red octopus, Enteroctopus megalocyathus, paralarvae rearing showed the highest mortalities. Part of this mortality has been attributed to cannibalism, so we studied the joint effect of paralarvae density and ...

Mass Mortality of Foundation Species on Rocky Shores: Testing a Methodology for a Continental Monitoring Program

open access: yesFrontiers in Marine Science, 2021
Global concern around substantial losses of biodiversity has led to the development of a number of monitoring programs. Networks were established to obtain appropriate data on the spatial and temporal variation of marine species on rocky shores. Recently,

Breeding origins of a uniquely regular migrant songbird in the Galápagos Islands

open access: yesEcology and Evolution, Volume 13, Issue 1, January 2023., 2023
Little is known about the causes and consequences of alternative pathways flown by long‐distance migratory birds. Using population genetic analyses, we compared samples from migratory Bobolinks stopping over in Galapagos with samples from seven locations across their breeding distribution to determine the migrant's breeding population of origin ...

Six new species of Anthuridae (Peracarida: Isopoda) from the southern Mexican Pacific

open access: yesEuropean Journal of Taxonomy, 2021
Marine isopods, despite being a very diverse group, have been little studied in the Mexican South Pacific. After a revision of 171 specimens collected from Guerrero and Oaxaca, six new species, belonging to five genera, were discovered: Amakusanthura ...

Seasonal Variation in Fatty Acid and Amino Acid Composition of the Patagonian Marine Polychaete Abarenicola pusilla and Its By‐Products

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
This study aims to provide a quantitative analysis of the amino acids (AAs) and fatty acids (FAs) found in by‐products of the Patagonian marine polychaete Abarenicola pusilla. Samples of polychaetes were taken in different seasons and processed to generate three by‐products: eviscerated whole body, press cake, and press liquid.

Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics

open access: yesJournal of Animal Ecology, Volume 90, Issue 7, Page 1623-1634, July 2021., 2021
Using tank‐bromeliads, the authors experimentally investigated for the first time how aquatic–terrestrial linkages are affected by warming in the tropics. In contrast to temperate regions, warming is predicted to cause strong declines in tropical aquatic insect emergence into terrestrial ecosystems, while variably affecting terrestrial detritus ...

Application of a Simple, Low-Cost, Low-Tech Method to Monitor Intertidal Rocky Shore Assemblages on a Broad Geographic Scale

open access: yesFrontiers in Marine Science, 2021
Identifying susceptible regions where biodiversity changes occur at fast rates is essential in order to protect and ameliorate affected areas. Large-scale coastal monitoring programs that focus on long-term variability are scarce, yet the Marine ...
