  • Asymmetry of mandibular dentition is associated with dietary specialization in snail-eating snakes

    Masaki Hoso

    PEERJ   5   e3011  2017.03  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Background, In vertebrates, the left-and-right pairs of homologous organs are generally present in equal numbers. A remarkable exception is known in the snail eating snakes of the family Pareidae: almost all the pareid snakes have much more teeth on the right mandible than on the left for functional specialization in feeding on the dextral majority of land snails. Because the only exceptional species with symmetric dentition has been regarded as a slug-eater, the extent of dietary specialization on slugs could shape the degree of the lateral asymmetry of mandibular dentition (dentition asymmetry) even among snail eaters.
    Methods. To test this, I compared the morphology and behavior of two sympatric species of Taiwanese snail-eating snakes, Pareas atayal and P, formosensis.
    Results. Specimens collected in the same locality showed that the dentition asymmetry of P. formosensis was significantly smaller than that of P. atayal. Congruent to its weak asymmetry, P, formosensis showed a strong preference of slugs to snails in the feeding experiment.
    Discussion. The dietary specialization of P. formosensis on slugs would contribute to niche partitioning from the sympatric congener P. atayal. This study suggests that the diverse variation in the dentition asymmetry of pareid snakes is the result of their dietary specialization and divergence.

  • Cost of autotomy drives ontogenetic switching of anti-predator mechanisms under developmental constraints in a land snail

    Proceedings of the Royal Society B: Biological Sciences   279 ( 1748 ) 4811 - 4816  2012.12

     View Summary

    Autotomy of body parts offers various prey animals immediate benefits of survival in compensation for considerable costs. I found that a land snail
    <italic>Satsuma caliginosa</italic>
    of populations coexisting with a snail-eating snake
    <italic>Pareas iwasakii</italic>
    survived the snake predation by autotomizing its foot, whereas those out of the snake range rarely survived. Regeneration of a lost foot completed in a few weeks but imposed a delay of shell growth. Imprints of autotomy were found in greater than 10 per cent of
    <italic>S. caliginosa</italic>
    in the snake range but in only less than 1 per cent out of it, simultaneously demonstrating intense predation by the snakes and high efficiency of autotomy for surviving snake predation in the wild. However, in experiments, mature
    <italic>S. caliginosa</italic>
    performed autotomy less frequently. Instead of the costly autotomy, they can use defensive denticles on the inside of their shell apertures. Owing to the constraints from the additive growth of shells, most pulmonate snails can produce these denticles only when they have fully grown up. Thus, this developmental constraint limits the availability of the modified aperture, resulting in ontogenetic switching of the alternative defences. This study illustrates how costs of adaptation operate in the evolution of life-history strategies under developmental constraints

  • Non-adaptive speciation of snails by left-right reversal is facilitated on oceanic islands

    Masaki Hoso

    Contributions to Zoology   81 ( 2 ) 79 - 85  2012.05

    Authorship:Lead author, Corresponding author

     View Summary

    The nearly neutral theory of molecular evolution predicts that small population size is essential for non-adaptive evolution. Evolution of whole-body left-right reversal in snails is generally a compelling example of non-adaptive speciation, because variants with reversed chirality would suffer from reduced mating opportunities within a population. Despite this reproductive disadvantage, sinistral snail species have repeatedly originated from dextral ancestors in terrestrial pulmonates. Here I show that snail speciation by reversal has been accelerated on oceanic islands. Analysing the global biogeography of 995 genera across 84 stylommatophoran families, I found that the proportion of sinistral snail genera was enhanced in genera endemic to oceanic islands. Oceanic islands are relatively small land masses offering highly fragmented habitats for snails. Thus, the upper limit of population size would probably have been small for a long time there. Oceanic islands may have facilitated the fixation of the nonadaptive allele for speciation by reversal, allowing subsequent ecological divergence of sibling species. This study illustrates the potential role of genetic drift in non-adaptive speciation on oceanic islands.
