| nepomorpha, gerromorpha and leptopodomorpha (hemiptera: heteroptera) of the tuscan archipelago (italy). | this paper provides the first checklists for nepomorpha (12 spp.), gerromorpha (10 spp.) and leptopodomopha (5 spp.) of the tuscan archipelago; summarizing and updating the knowledge for this area. the presence of the family micronec- tidae is recorded for the first time in the archipelago, as well as six species: nepomorpha - micronecta scholtzi (fieber, 1860), sigara selecta (fieber, 1848), s. stagnalis (leach, 1817), s. lateralis (leach, 1817); gerromorpha - gerris asper (fieber, 1860); lepto ... | 2013 | 26312344 |
| aquatic heteroptera (nepomorpha, gerromorpha) in small intermittent rivers of ukraine steppe zone. | small intermittent rivers are some of the most widespread types of water currents in the steppe zone. in the ecosystems of the intermittent rivers we have found 28 species of water bugs that compose the majority of the described fauna in the south ukraine. our study added two new species to the faunistic list of this zone (sigara fossarum, hydrometra gracilenta), and finally confirmed the presence of micronecta scholtzi in ukraine. we also studied the seasonal changes of biotopic distribution an ... | 2013 | 24039514 |
| extreme call amplitude from near-field acoustic wave coupling in the stridulating water insect micronecta scholtzi (micronectinae). | underwater acoustic transducers, particularly at low frequencies, are beset by problems of scale and inefficiency due to the large wavelengths of sound in water. in insect mating calls, a high call volume is usually desirable, increasing the range of signal transmission and providing a form of advertisement of the signaller's quality to a potential mate; however, the strength of the call is constrained by body size and by the need to avoid predators who may be listening in. male crickets and wat ... | 2018 | 29321267 |
| so small, so loud: extremely high sound pressure level from a pygmy aquatic insect (corixidae, micronectinae). | to communicate at long range, animals have to produce intense but intelligible signals. this task might be difficult to achieve due to mechanical constraints, in particular relating to body size. whilst the acoustic behaviour of large marine and terrestrial animals has been thoroughly studied, very little is known about the sound produced by small arthropods living in freshwater habitats. here we analyse for the first time the calling song produced by the male of a small insect, the water boatma ... | 2011 | 21698252 |
