| aquatic and semiaquatic heteroptera (nepomorpha and gerromorpha) fauna of greek holiday islands (rhodes, crete and corfu) with first records of three species from europe and greece. | a comprehensive survey on aquatic and semiaquatic bugs (heteroptera: nepomorpha and gerromorpha) of three greek holiday islands, rhodes, crete and corfu, was conducted from 2007 to 2010 at 237 localities. in this paper, hundreds of detailed records for 30 taxa in nine families are given. the occurrences of rhagovelia infernalis africana lundblad, 1936 and velia mariae tamanini, 1971 are confirmed and recorded for the first time from europe sensu stricto. additionally, some notes on morphology, t ... | 2017 | 28187549 |
| competitive interactions limiting the number of species in rock pools: experiments with sigara nigrolineata. | rock-pool corixids (hemiptera) arctocorisa carinata and callicorixa producta were excluded from small rock pools. first-stage larvae of sigara nigrolineata, separately or together with larvae of either of the rock-pool species, were then introduced daily at a rate simulating reproduction by typical populations. in all three treatments, the survival of s. nigrolineata larvae was high at the beginning of experiment, 0.39-0.83 between the 1st and 5th stages, but later high mortality was observed. c ... | 1993 | 28312945 |
