cytogenetics analysis and testis morphology of aquatic species of the families belostomatidae, gelastocoridae, gerridae, notonectidae, and veliidae (heteroptera).	the heteroptera have holocentric chromosomes with kinetic activity restricted to the end of chromosomes. the first meiotic division is reductional for the autosomes and equational for the sexual. only a few species of this suborder have been analyzed. in this study, we observed the morphologies of the testes of the heteroptera species belostoma anurum (herrich-schäffer, 1948), belostoma micantulum (stal, 1858), gelastocoris angulatus (melin, 1929), gelastocoris flavus flavus (guérin-méneville, 1 ...	2015	25797798
distribution and fluctuations of backswimmers (notonectidae) in a tropical shallow lake and predation on microcrustaceans.	notonectids are widely distributed in freshwaters and can prey on zooplankton in temperate lakes. however, its role in structuring the zooplankton community is unknown in tropical lakes. thus, our objective was to study the notonectid martarega uruguayensis in a brazilian tropical shallow lake to evaluate its potential as a zooplankton predator. its horizontal distribution was analized in the lake throughout one year in fortnightly samplings. backswimmers were more abundant (mean density 162.9 ± ...	2016	27409228
