Vabalų (Insecta, Coleoptera)fauna ir paplitimas Lietuvos pajūrio buveinėse / Beetle (Insecta, Coleoptera) fauna and its distribution in seashore habitats of Lithuania

Ferenca, Romas 06 October 2014 (has links)
Baltijos pajūris išsiskiria savita gamta, specifinėmis, tik šiam regionui būdingomis buveinėmis, kurias sukuria švelnus jūrinis klimatas, nederlingi ir druskingi smėlio dirvožemiai, vyraujantys vakarų vėjai. Darbo tikslas – ištirti Baltijos pajūrio buveinių vabalų (Insecta, Coleoptera) fauną, pasiskirstymą buveinėse ir jų sezoninę dinamiką. Vabalai tirti 2008-2010 m. 10 skirtingų Baltijos pajūrio buveinių. Baltijos pajūrio buveinėse nustatytos 1206 vabalų rūšys, priklausančios 70 šeimų, kas sudaro 32,7 % nuo visų žinomų vabalų Lietuvoje. Atrastos 52 naujos Lietuvos faunai vabalų rūšys, priklausančios 16 šeimų. Rūšis Cryptocephalus ochroleucus Fairm. yra nauja visam Rytų Pabaltijui ir Fenoskandijai. Didžiausia vabalų įvairovė nustatyta sengirėje (174 rūšys), mažiausia – pilkosiose kopose apaugusiose samanomis ir kerpėmis (20 rūšių). Atvirose Baltijos pajūrio buveinėse dominuoja termofilinės, psamofilinės vabalų rūšys. Stenotopinės vabalų rūšys (89) ir halobiontinės (27 rūšys) yra būdingos atviroms pajūrio buveinėms, o halobiontinės rūšys – pilkosiose ir baltosiose kopose su Leymus arenarius. / The Baltic Sea coast typical habitats formed by a mild sea climate are characterized by infertile and saline sands, predominant western winds and are peculiar only to this region. The aim of the study is to investigate the beetle (Insecta, Coleoptera) fauna of seashore habitats of Lithuania, beetle distribution in different habitats. The material was collected during the study period of 2008–2010 in 10 different localities of Curonian Spit. Research territories were selected so that investigated plots covered all habitats of the Baltic Sea coast. After analyzing and generalizing the material collected in the Baltic seashore habitats a total of 1206 beetle species belonging to 70 families, or 32.7% of all known Lithuanian beetle fauna were determined; 52 beetle species of 16 families were recorded first time for Lithuania. Cryptocephalus ochroleucus Fairm. is a new species in the Eastern Baltic region and in Fennoscandia. The old-growth mixed forest distinguished by the greatest species number (174 beetle species) and grey dunes overgrow with lichens, mosses and Poaceae exibited the lowest species number (20 beetle species). The open habitats of the Baltic Sea coast were dominated by termophilic psamophilic beetle species. Stenotopic (89 species) and halobiontic (27 species) beetle species were typical only of open seashore habitats. Halobiontic species were the most abundant in the grey / white dunes with Leymus arenarius.

Beetle (Insecta,Coleoptera) fauna and its distribution in seashore habitats of Lithuania / Vabalų (Insecta, Coleoptera) fauna ir paplitimas Lietuvos pajūrio buveinėse

Ferenca, Romas 06 October 2014 (has links)
Typical habitats of Baltic seashore habitats are characterized by infertile saline sands and predominant western winds. The current Baltic sea coast habitats are the result of human activities. This landscape is one of the youngest and the same time one of the most sensitive. The beetles of Baltic seashore habitats have been investigated only fragmentarly, and there is no research data about the Baltic Sea costal beetle complexes. The aim of this study is to investigate the beetle fauna and distribution in different habitats of Baltic seashore of Lithuania. / Baltijos pajūriui būdingi nederlingi ir druskingi smėlio dirvožemiai, dominuojantys vakarų vėjai.Dabartinės Baltijos pajūrio buveinės, tai aktyvios žmonių veiklos rezultatas, ir tuo pačių vienas jauniausių ir labiausiai pažeidžiamų Lietuvos kraštovaizdžių. Baltijos pajūrio vabzdžiai buvo tyrinėjami tik fragmentiškai, Iki šiol nebuvo atlikti Baltijos pakrančių buveinių vabalų kompleksų tyrimai. Šio darbo tikslas - ištirti Baltijos pajūrio buveinių vabalų fauną ir paplitimą buveinėse.

Vertical zonation of three species of California limpets (Acmaeidae) as a function of predation

Bros, William Ernest 01 January 1978 (has links)
Various studies indicate the acmaeid limpet species Collisella digitalis, Collisella pelta and Notoacmea scutum inhabit different vertical zones in the rocky-intertidal region. At Sunset Bay, Oregon, Shotwell (1950) found that C. digitalis was situated in the upper intertidal C. pelta inhabited the mid-intertidal and N. scutum was located in the mid to lower zone in the rocky-intertidal region. Frank (1965) observed the same distribution patterns at Coos Bay, Oregon as did the author in the rocky-intertidal region near Dillon Beach, California. Species distributions in the rocky-intertidal region are thought to be limited from above by physical stress and from below by predation or competition (Connell 1970; Dayton 1971; Vermeij 1972; Paine 1974; Bertness 1977). The purpose of the present study was to investigate effects of the predators Pisaster ochraceus, Cancer antennarius and Pachygrapsus crassipes on the distributions of the three acmaeid limpet species particularly with respect to their lower limits.
