Abstract

Ponikva Sovljak nalazi se na istočnom obronku Velike Kapele. Oblikovana je u karbonatnim naslagama gornjojurske starosti, a predisponirana je izrazitim tektonskim pukotinama. Poligenetskog je postanka, nastala djelovanjem procesa korozije, padinskih procesa i urušavanja. U razdoblju od travnja do rujna 2015. godine na području ponikve provedena su mikroklimatološka mjerenja memorijskim termohigrografima. Prikupljeni su podaci o temperaturi zraka, relativnoj vlažnosti zraka i temperaturi rosišta na različito eksponiranim padinama i na njenom dnu. Također je u istom razdoblju istraživana i flora. Popisivane su biljne vrste koje rastu na različitim ekspozicijama i na dnu ponikve, koje su potom bile podvrgnute analizi ekoloških indikatorskih vrijednosti i životnih oblika. Ukupno je zabilježeno 107 biljnih svojti, od kojih najveći udio čine svojte iz porodice Lamiaceae. Raspodjela biljnih svojti i rezultati analize ekoloških indikatorskih vrijednosti ukazali su na prisutnost inverzije vegetacije u ponikvi, kao posljedice posebnih mikroklimatoloških uvjeta u ponikvi, odnosno prisutstva inverzije temperature zraka.

Abstract (english)

The Sovljak doline is located on the eastern slope of the Velika Kapela mountain. It was formed in Upper Jurassic carbonate layers, where intense tectonic fractures facilitated its formation. Corrosion, slope processes and collapse occurring in the doline suggest its polygenetic origin. From April to September 2015, microclimatic measurements, including air temperature, relative humidity and dew point were made in the doline at three different locations using data loggers. Flora inventory was also made in that period. Plants growing at various slope expositions and at the bottom of the doline were registered, and they underwent the analysis of ecological indicator values and life forms. Altogether 107 plant taxa were registered, most of which belong to family Lamiaceae. Microclimatic measurements proved the temperature inversion in the doline, which also implicated the occurrence of the vegetation inversion, shown by distribution of plant taxa and by the results of the ecological indicator values analysis.
