     概要を見る

    <jats:title>Abstract</jats:title> <jats:p>The West Indian sweetpotato weevil, Euscepes postfasciatus (Fairmaire), is one of the pests of the sweet potato, Ipomoea batatas, in tropical and subtropical countries. Although an eradication program using the sterile insect technique (SIT) for this weevil is now underway in Japan, the lack of potent attractants such as sex pheromones for this weevil species prevents effective monitoring and hampers pest control operations. New methods to monitor the performance of sterile males using trapped wild females are needed. In this study, we tested whether the ejaculate of the labeled males that were fed an artificial diet labeled with the trace element, rubidium (Rb), is detectable in the fertilized females. We fed an artificial diet treated with Rb (1.00, 0.50, 0.25, and 0.00%) to adult male weevils for 14 d after emerging and quantified the rubidium content in inseminated females. We also examined the side effects of the artificial diet on mating performance and longevity. The advantages of monitoring the spatial level of sterility using data from females labeled with ejaculate of Rb-fed males in an SIT eradication program are discussed.</jats:p>

     概要を見る

    Evolutionary ecological theory suggests that selection arising from interactions with conspecifics, such as sexual and kin selection, may result in evolution of intraspecific conflicts and evolutionary 'tragedy of the commons'. Here, we propose that such an evolution of conspecific conflicts may affect population dynamics in a way that enhances species coexistence. Empirical evidence and theoretical models suggest that more abundant species is more susceptible to invasion of 'selfish' individuals that increase their own reproductive success at the expense of population growth (intraspecific adaptation load). The density-dependent intraspecific adaptation load gives rise to a self-regulation mechanism at the population level, and stabilizes species coexistence at the community level by negative frequency-dependence.

  • Idea paper: Airport ecology, an environment without predation pressure drives evolution

     概要を見る

    Evolutionary changes in organisms are directly observable, and they can occur rapidly in the presence of strong natural selection. Here, we present the "airport ecology" to describe the rapid evolution of animals. The pygmy grasshopperTetrix japonicaexhibits significant variations in pronotum color and markings and is a good model organism for "airport ecology." There are trade-offs in black-spot markings in the pygmy grasshoppers; although it helps in camouflaging and reducing predation pressure, it stimulates overheating, resulting in a reduction in mating opportunities and foraging success under high solar irradiance. Therefore, the frequency of black-spotted morphs is lower at lower latitudes than at higher latitudes along a latitudinal cline. However, in an airport where predation pressure is reduced by the removal of predatory bird populations, we predict that the frequency of black-spotted morphs ofT. japonicawill be lower in habitats without predators than in those with predators at the same latitude; this demonstrates the anthropogenic effect onT. japonicapolymorphism. As suggested here, predator-free environments such as airports are valuable for illustrating the effects of anthropogenic activity on animal evolution. These findings can be extended to several other species that are found around airports and are potentially preferred by avian predators in terms of not only rapid evolution of color polymorphism but also evolution of various life-history traits.
