Frugivorous weevils are too rare cause Janzen-Connelll effects in New Guinea lowland rain forest

Popis výsledku v původním jazyce

Seed predators may play a particularly important role in tropical rain forests as a highly specialized guild of herbivores that can destroy a large proportion of seed crops, thus influencing the population dynamics of individual plant species as well asoverall plant diversity. Therefore, this study examines the abundance, species richness and host specificity of frugivorous weevils on a phylogenetically diverse sample of plants in the lowland rain forest of Papua New Guinea, testing two key prerequisites, that they are host specific and cause significant seed mortality, for them to be a potentially important mortality factor in maintaining plant diversity in tropical forests. Further, we test the hypothesis that seed-eating species exhibit higher hostspecificity than flesh-eating species, responding thus to the more specialized plant defences of seeds. We studied community of frugivorous weevils by quantitative rearing of 57 weevil species represented by 10 485 individuals from 326 w
