Zooplancton en la larvicultura de peces neotropicales

Revista MVZ Córdoba, 2008
La larvicultura de peces neotropicales altriciales presenta limitaciones para el manejo de la primera alimentación dado el pobre desarrollo del tracto digestivo y capacidad natatoria. La alimentación de la larva debe considerar el tamaño, densidad y calidad de la presa ofrecida.

Shifts in the seasonal trophic ecology of larvae and juveniles of European hake (Merluccius merluccius): From the Galician upwelling system (NW Spain)

Fisheries Oceanography, Volume 31, Issue 5, Page 539-553, September 2022., 2022
Abstract The trophic ecology of European hake (Merluccius merluccius) larvae and early‐juveniles from the Iberian shelf off Galicia (NW Spain) are assessed by means of stable isotopes (SIA) and nutritional condition in conjunction with hydrobiological variations observed during the winter and summer season of 2012.

Testing Bergmann's rule in marine copepods

Ecography, Volume 44, Issue 9, Page 1283-1295, September 2021., 2021
Macroecological relationships provide insights into rules that govern ecological systems. Bergmann's rule posits that members of the same clade are larger at colder temperatures. Whether temperature drives this relationship is debated because several other potential drivers covary with temperature.

Reverse diel vertical movements of oceanic manta rays off the northern coast of Peru and implications for conservation

Ecological Solutions and Evidence, Volume 2, Issue 1, January–March 2021., 2021
Manta photo supplied by Stephanie Venables Recovered satellite tags revealed fine‐scale reverse diel vertical movements of oceanic manta rays in the coastal and highly stratified waters of northern Peru. Movements appeared to be driven by a strategy of foraging and thermal recovery.

Habitat light sets the boundaries for the rapid evolution of cichlid fish vision, while sexual selection can tune it within those limits

Molecular Ecology, Volume 29, Issue 8, Page 1476-1493, April 2020., 2020
Abstract Cichlid fishes' famous diversity in body coloration is accompanied by a highly diverse and complex visual system. Although cichlids possess an unusually high number of seven cone opsin genes, they express only a subset of these during their ontogeny, accounting for their astonishing interspecific variation in visual sensitivities. Much of this
