Strategy combining mammalian fats with supplementation of pungent spices in aqu...
Ruiz, Alberto; Gisbert, Enric; Estevez, Alicia; Reyes-López, Felipe E.; Vallejos-Vidal, Eva; Tort, Lluís; Dias, Jorge; Engrola, Sofia; Magalhães, SaraThe replacement of fish oil (FO) in aquafeeds usually leads to imbalances in the dietary content of n-3 and n-6 polyunsaturated fatty acids (PUFA), with negative consequences for fish performance, health, and fillet quality. Animal-rendered fats are an alternative lipid source high in saturated fatty acids, potentially sparing n-3 PUFA from oxidation, and with lower n-6 PUFA contents than plant-based oils, espe...
Trait-Specific Indirect Effects Underlie Variation in the Response of Spiders t...
Henriques, Jorge F.; Lacava, Mariángeles; Guzman, Celeste; Gavin-Centol, Maria Pilar; Ruiz-Lupión, Dolores; Ruiz, Alberto; Viera, CarmenIn cannibalistic species, selection to avoid conspecifics may stem from the need to avoid being eaten or to avoid competition. Individuals may thus use conspecific cues to modulate their behavior to such threats. Yet the nature of variation for such cues remains elusive. Here, we use a half-sib/full-sib design to evaluate the contribution of (indirect) genetic or environmental effects to the behavioral response...
