“…Thus, it is possible that the most frequent tactic of nest relocation adopted by the males involves moving to another fallen log nearby. Given that males can also occupy abandoned nests in the same fallen log (Quesada‐Hidalgo et al., 2019), an interesting question is whether empty nests located in more protected zones are reoccupied faster than empty nests located in less protected zones.…”

“…The number of eggs received by a male is positively related to the integrity of his nest, so that males with well‐preserved nests have higher reproductive success (Rojas et al., 2019). Eggs laid by females are actively protected by the males, which are able to repel predators, such as ants, conspecifics, and earthworms (Quesada‐Hidalgo et al., 2019). If a nest‐owner male dies or deserts, his nest may be promptly occupied by another male that may even care for the unprotected eggs (Quesada‐Hidalgo et al., 2019).…”

Nest‐site selection in a neotropical arachnid with exclusive male care: Proximate cues and adaptive meaning

Nest‐site selection is a crucial decision made by parents because inadequate sites may expose the offspring and the parent to harsh abiotic and biotic conditions. Although nest‐site selection has been reported for some species of arthropods, the proximate cues used by parents to select the nest site and the adaptive meaning of nest‐site selection are still poorly understood. We investigated nest‐site selection in the harvestman Quindina limbata, in which males build mud nests on the surface of fallen logs and perform parental care. This species inhabits tropical forests where rainfall destroys nearly 50% of the nests, representing an important selective force shaping nest‐site selection. We followed 139 nests and recorded the position (angle) where these nests were located on the fallen log surface. Males showed a complex pattern of nest‐site selection that responded to three proximate cues: the direct impact of raindrops on the upper half of the fallen log, the drag force caused by flowing water on the laterals of the fallen log, and water saturation on the lowest part of the fallen log. These selective pressures created a bimodal pattern of nest distribution on the lower half of the fallen logs. The peaks of this distribution occurred in places where nests are protected from the direct impact of raindrops, the drag force caused by flowing water is not high, and the risk of nest flooding is low. The possible adaptive meaning of nest‐site selection is to minimize the risk of nest destruction, which imposes energetic costs to males that need to build another nest. Nest‐site selection may also minimize reproductive costs because males with damaged nests show decreased attractiveness to females. Finally, nest‐site selection may increase offspring fitness minimizing the risk of egg mortality associated with nest destruction and anoxia when nests are flooded.

Parental care is widespread across the animal kingdom. Parental behaviours are beneficial by increasing offspring survival but induce significant costs to the parents. Because parental care is far more common in females, the associated reproductive costs have been largely studied in this sex. Although male parental care is likely to involve significant costs, it has been markedly less well investigated. We studied the costs of egg-carrying on locomotor performance in an amphibian species (Alytes obstetricans) with male parental care. We examined complementary parameters including hopping performance, righting response, hindleg muscle response to egg burden, and homing time in males carrying or not carrying eggs. We found that carrying males showed altered locomotor performance for most traits. In addition, alteration of performance was closely related to relative clutch size. Clutch desertion occurred in smaller individuals carrying larger relative clutch mass, and performance after desertion was similar to that of non-reproductive individuals. Overall, our study demonstrates that carrying eggs significantly alters male mobility and that performance–clutch size trade-offs are relevant in understanding the evolution of paternal care.

“…1B). Field experiments with Q. albomarginis and Q. limbata showed that male presence inside the nest is crucial for offspring survival because eggs in unattended nests may be attacked by fungi or consumed by predators, such as ants and conspecifics (Mora 1990;Quesada-Hidalgo et al 2017). Moreover, females of both species seem to copulate exclusively with nest-owning males and carefully inspect nest structure before copulating and laying eggs (Mora 1990, Toscano-Gadea andRojas 2014).…”
