| sexual selection of male parental care in giant water bugs. | paternal care can be maintained under sexual selection, if it helps in attracting more mates. we tested the hypothesis in two giant water bug species, appasus major and appasus japonicus, that male parental care is sexually selected through female preference for caring males. females were given an opportunity to choose between two males. in the first test of female mate choice, one male carried eggs on its back, while the other did not. the egg status was switched between these two males in the ... | 2016 | 27293778 |
| contrasting genetic structure of closely related giant water bugs: phylogeography of appasus japonicus and appasus major (insecta: heteroptera, belostomatidae). | appasus japonicus and a. major, two belostomatid species of the giant water bug found in parts of east asia, have very similar morphological characteristics and ecological niches, and also overlapping habitats. however, the results of our previous published study utilizing molecular phylogenetic analyses of mitochondrial and nuclear dna revealed extensive genetic differences, which indicated that the possibility of inter-specific hybridization was extremely unlikely. we collected a. japonicus an ... | 2014 | 24398367 |
