“…Cooperative behaviors may entail sharing reproductive duties (Emlen and Wrege 1988), predator-warning (Sherman 1977), or assistance in acquiring mates (Krakauer 2005). In tadpoles, mechanisms for cooperation may include competitive restraint (reducing exploitative competition), decreased interference with competitors (thereby increasing time available for foraging), or beneficial behaviors such as stirring up more periphyton than they can consume (Waldman 1991, Hokit andBlaustein 1997). However, these beneficial behaviors may be counteracted by genetic similarities between kin that increase the potential for exploitative competition, potentially canceling out effects of cooperation (Griffiths and Armstrong 2001).…”

“…Previous studies that have addressed the effect of kinship on growth variation have shown conflicting results. For example, in Rana temporaria, full-sib treatments had lower variation in growth rate and mass at metamorphosis (Pakkasmaa and Aikio 2003), while Hokit and Blaustein (1997) found that mass was more skewed towards small tadpoles in mixed groups compared to kin groups.…”

“…However, empirical studies testing this hypothesis have shown conflicting results. While some studies on fish and amphibians have found higher variation in growth in sibling groups (Beacham 1989, Waldman 1991, others have found the opposite result (Hokit and Blaustein 1997, Anderson and Sabado 1999, Pakkasmaa and Aikio 2003, Saidapur and Girish 2001, Girish and Saidapur 2003.…”

The effect of kinship on intraspecific competition in larvae of the poison frog Ameerega bassleri (Anura, Dendrobatidae). According to inclusive fitness theory, cooperation between related individuals should ameliorate the effect of intraspecific competition. However, close relatedness is also thought to increase similarity between individuals and therefore increase the risk of exploitative competition. Studies of the effects of kinship in larval amphibians have produced mixed results concerning these two hypotheses. We examined the effect of kinship on the mean and variation of mass after 30 days of growth in groups composed of either pure siblings or a mixture of five different sibships in a species of poison frog, Ameerega bassleri. We found no significant differences between sibling and mixed treatments with respect to mass or variation in mass. Our results are consistent with other studies in larval anurans which have found no differences between sibling and mixed treatments, suggesting that the effects of kin selection and genetic similarity between competitors may in some cases cancel each other out.

Kin discrimination in tadpoles of Hylarana temporalis (Anura: Ranidae) and Sphaerotheca breviceps (Anura: Dicroglossidae) hydroperiod and social habits

Kin discrimination in tadpoles of Hylarana temporalis (Anura: Ranidae) and Sphaerotheca breviceps habits. Kin discrimination ability was studied in tadpoles of and , which live in two distinctly different habitats; the former shows social aggregation and the latter live scattered. Early in development, tadpoles of are found in small aggregations in the streams of Western Ghats but in later stages they are generally seen in isolated pools cut off from the main channel following drying up of the stream.breed during south-west monsoons in tadpoles living in aggregation exhibit kin discrimination while those not living in aggregation may not exhibit kin discrimination. Further, tadpoles that face desiccation threat may also not exhibit kin discrimination behavior. Tests were conducted on tadpoles of the above two species at two developmental stages (Gosner Stages 28-30 and 34-36) to reveal their association choice with sibs and non-sibs. Tadpoles of associated with both familiar (reared with sibs) and unfamiliar (reared in isolation) sibs in early but not in later stages of development. Tadpoles of showed no association important in later stages of development taking place in pools of water bodies that face desiccation. Absence of kin recognition in is associated with their lack of natural aggregation and perennial desiccation threat of the ephemeral ponds. We suggest that kin discrimination behavior in tadpoles is related to their social habits and hydroperiod of their habitat.

Five clutches of Rana temporalis eggs collected along a stream were reared separately until formation of Gosner stage 25 tadpoles. The effect of kinship and density was then studied by rearing ten siblings in 1 (sib 1) or 5 (sib 5) l water, and mixed rearing of ten tadpoles (2 from each of the 5 clutches) in 1 (mix 1) or 5 (mix 5) l water; each group replicated five times. In all the groups tadpoles showed a sigmoid growth curve. Both kinship and density interacted to affect mean proportions of individuals reaching metamorphic climax (MC), mean body mass, and size frequency at MC (day 79). The proportion of tadpoles reaching MC was highest in sib 5 (82%) followed by mix 5 (77%), sib 1 (73%), and mix 1 (64%) groups. Crowding plus mixing significantly lowered the median developmental stage mean body mass and broadened the spectrum of developmental stages or size classes at MC. The size difference of individuals at MC was inversely related to density of rearing. Frequency of different developmental stages was comparable in sib 1, sib 5, and mix 5 groups. Interestingly, small individuals were significantly greater in number in the mix 1 group compared to sib 1. The above findings suggest that genotypic heterogeneity in conjunction with crowding retards growth rate of tadpoles in comparison with those reared in a genetically homogenous (sib) environment. Further, they suggest that the adverse effect of mixed rearing is context dependent.
