Sex-specific trait architecture in a spider with sexual size dimorphism
Simona Kralj-Fišer, Matjaž Kuntner, Paul Vincent Debes
Izvirni znanstveni članek

Sexual dimorphism, or sex-specific trait expression, may evolve when selection favours different optima for the same trait between sexes, that is, under antagonistic selection. Intra-locus sexual conflict exists when the sexually dimorphic trait under antagonistic selection is based on genes shared ...

It’s complicated: how sex, family and season affect growth of a sexually size dimorphic spider

Female-biased sexual size dimorphism (SSD), where females are larger than males, is widespread. While ultimate explanations for SSD are well established, the proximate developmental mechanisms remain poorly understood. Studying sex-specific growth trajectories to identify common versus sex-specific ...

Larger females do not achieve higher lifetime fecundity in an extremely size-dimorphic spider

Female body size is often linked positively to clutch fecundity because size limits the number of eggs or offspring produced per clutch. Yet larger clutches may not increase lifetime reproductive success if offset by fewer reproductive events, shorter lifespan, reduced offspring survival, or mating- ...
