Body size, nuptial gift characteristics and courtship behaviour, among other traits, can reflect the quality of a potential mate and, thus, might be under sexual selection. To maximize their mating success, individuals can show behavioural plasticity in sexual context. Allocosa senex is a burrow-digging wolf spider that exhibits reversal in courtship roles and in sexual size-dimorphism expected for spiders.

- The immune response carries costs, with trade-offs between immunity and reproduction noted in various arthropod species, leading to expected sex differences in immune function.
- Research conducted on the burrowing wolf spider Allocosa senex found that female spiders displayed higher lytic activity than males, indicating stronger immune responses.
- Additionally, males that dug deeper burrows exhibited increased lytic activity, suggesting that their behavior influences their immune responses, while no correlation was found between male body condition and burrow length, a trait influenced by female choice.
Natural selection shapes prey-predator relationships and their behavioral adaptations, which seek to maximize capture success in the predator and avoidance in the prey. We tested the ability of adults of the scorpion Bothriurus bonariensis (Bothriuridae) to prey on synchronous and sympatric adults harvestmen of Acanthopachylus aculeatus, Discocyrtus prospicuus, Parampheres bimaculatus and Pachyloides thorellii (Gonyleptidae).
