A population of Stratiomys japonica, a species belonging to the family Stratiomyidae (Diptera), common name 'soldier flies', occurs in a hot volcanic spring, which is apparently among the most inhospitable environments for animals because of chemical and thermal conditions. Larvae of this species, which naturally often experience temperatures more than 40(More)
Previously, we described the heat shock response in dipteran species belonging to the family Stratiomyidae that develop in thermally and chemically contrasting habitats including highly aggressive ones. Although all species studied exhibit high constitutive levels of Hsp70 accompanied by exceptionally high thermotolerance, we also detected characteristic(More)
Heat shock protein 70 (Hsp70) is the major player that underlies adaptive response to hyperthermia in all organisms studied to date. We investigated patterns of Hsp70 expression in larvae of dipteran species collected from natural populations of species belonging to four families from different evolutionary lineages of the order Diptera: Stratiomyidae,(More)
The biting midges larvae fauna of the intertidal and supralittoral zones in Sel'dianaia small bay (Kandalaksha Bay of the White Sea) is studied. It is represented by Stilobezzia sp., Dasyhelea sp. and Culicoides manchuriensis immature stages. Their distribution displays the strict vertical zonation. The abundance of larvae collected differs strongly at the(More)
The heat shock proteins belonging to the Hsp90 family (Hsp83 in Diptera) play a crucial role in the protection of cells due to their chaperoning functions. We sequenced hsp90 genes from three species of the family Stratiomyidae (Diptera) living in thermally different habitats and characterized by extraordinarily high thermotolerance. The sequence variation(More)
Transitions in habitats and feeding behaviors were fundamental to the diversification of life on Earth. There is ongoing debate regarding the typical directionality of transitions between aquatic and terrestrial habitats and the mechanisms responsible for the preponderance of terrestrial to aquatic transitions. Snail-killing flies (Diptera: Sciomyzidae)(More)
The structure of the hsp70 gene cluster was investigated for two species of the family Stratiomyidae (Diptera), Stratiomys singularior and Oxycera pardalina. Their larvae inhabit nearshore-aquatic biotopes with contrasting temperature regimes, composition and concentration of salts. It was shown that the S. singularior hsp70 gene cluster contains five(More)
