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...
The sources of variation for individual prey-to-predator size ratios
Henriques, Jorge; Lacava, Mariángeles; Guzmán, Celeste; Gavín-Centol, Maria Pilar; Ruiz-Lupión, Dolores; De Mas, Eva; Magalhaes, S; Moya-Laraño, JordiThe relative body size at which predators are willing to attack prey, a key trait for predator-prey interactions, is usually considered invariant. However, this ratio can vary widely among individuals or populations. Identifying the range and origin of such variation is key to understanding the strength and constraints on selection in both predators and prey. Still, these sources of variation remain largely unk...
