“…In both species, as in other varunid crabs, copulation occurs during the intermolt period without precopulatory courtship behavior, and only females whose gonopores are decalcified can copulate (Fukui 1994;Brockerhoff & McLay 2005;Nara et al 2006;Sal Moyano et al 2014). Some varunid species exhibit pre-and post-copulatory guarding (Brockerhoff & McLay 2005;Nara et al 2006;Sal Moyano et al 2014), but no mate guarding has been observed in the dimorphic species, H. takanoi: A male simply approaches the female, grasps and handles her with his chelae and walking legs, and maneuvers her into the copulatory posture, during which the male and female embrace with the female on top (Miyajima et al 2012). However, in the non-dimorphic species H. sinensis, males sometimes guard females after copulation, and unlike the dimorphic species, the initiation of mating involves the approach of either the male or female, and males rarely capture females with their chelae (Miyajima et al 2012).…”

Many animals have unique morphological characters that function in social behavior. Sexual selection can affect the expression of such traits in males and females, leading to sexual dimorphism. We investigated the social function of setal patches on the chelae of two species of varunid crabs, one in which males, but not females, have setal patches (Hemigrapsus takanoi), and one in which both sexes have setal patches (Hemigrapsus sinensis). We experimentally removed setal patches and compared fighting and mating behavior of individuals with and without setal patches. In H. sinensis, males with setal patches removed were inferior fighters compared to intact males. In male H. takanoi and female H. sinensis, setal removal did not influence the outcome of fights. In mating, males lacking setal patches had a similar ability to copulate with females as intact males in both species. However, male H. takanoi with their setae removed tended to take more time to initiate copulation than did intact males. When females were given the opportunity to choose intact males or males without setal patches, females of H. takanoi did not discriminate between the two. Female H. sinensis, however, copulated with intact males more frequently compared to males lacking setal patches. Male H. sinensis showed no preferences for the presence of setal patches or the body size of females. Thus, our results indicate that setal patches have a social function in male H. takanoi and male H. sinensis, but not in female H. sinensis, suggesting that the setal patches of male crabs are a sexually selected trait in both species. However, the social function of male setal patches was more prominent in the species in which both sexes possess setal patches than in the species in which only males bear setal patches.

“…Burrow ownership means that it would be better to sit and wait for females to arrive rather than go in search of them. Previous work studied pre-copulatory guarding in N. granulata and demonstrated that copulation duration depend on diverse factors such as the OSR, female mating history and physical characteristics of the study area in different populations (Sal Moyano et al 2014a). Thus, we hypothesize that post-copulatory guarding behavior of N. granulata varies according to the diverse biological and physical factors in different populations.…”

Variation in the post‐copulatory guarding behavior of Neohelice granulata (Brachyura, Grapsoidea, Varunidae) in two different habitats

Crab guarding behaviors are influenced by the biological and physical characteristics that each population experiences in a particular habitat. We studied post‐copulatory guarding behavior and the factors affecting it, such as the presence of burrows, female receptivity duration, operational sex ratio (OSR) and male size, in two different populations of Neohelice granulata: Mar Chiquita coastal lagoon (MCL) and San Antonio Oeste (SAO). Laboratory experiments showed that post‐copulatory guarding duration varied between the study areas. In MCL, it depended upon the presence of burrows and female receptivity duration, whereas it was independent of the OSR and male size. In SAO, it was dependent upon the OSR and female receptivity duration, whereas it was independent of the presence of burrows and male size. Thus, N. granulata males display different reproductive strategies related to their post‐copulatory guarding behavior pattern in different habitats. These strategies are related to the fact that this species constructs and defends a burrow that provides shelter and a place to mate, something that other varunids do not have.
