Abstract

Istraživanje dobne strukture i relativne gustoće populacije kućnog macaklina (Hemidactylus turcicus L.) provedeno je na otocima Hvaru i Visu u razdoblju od 2002. do 2006. godine. 21 lokacija na Visu i 51 lokacija na Hvaru bile su obuhvaćene u transekt i obilažene jednom mjesečno tokom cijele godine. Jedinke su prebrojavane tokom jutra, dana, večeri i noći pri čemu su razlikovani odrasli i mladi. Dobiveni rezultati ukazuju na promjene dnevne i sezonske aktivnosti kućnog macaklina. Relativna gustoća populacije odraslih znatno je veća od relativne gustoće populacije mladih. Relativna gustoća alopatrijske populacije odraslih na Visu značajno je veća od relativne gustoće simpatrijske populacije odraslih na Hvaru. Smanjena gustoća populacije kućnog macaklina na Hvaru proizlazi iz pojave zidnog macaklina (Tarentola mauritanica L.) kada žive skupa na staništu, ali i različitih stanišnih uvjeta koji vladaju na tom otoku što je vidljivo kroz smanjenu gustoću na lokacijama na kojima se pojavljuje isključivo kućni macaklin.

Abstract (english)

The study of age structure and relative population density of the Mediterranean gecko (Hemidactylus turcicus L.) was conducted on the islands of Hvar and Vis during the period from 2002 until 2006. The total of twenty one locations on Vis and fifty one on Hvar were included in a transect and then visited once a month during the whole year. Individuals were counted in the morning, afternoon, evening and night during which time adult geckoes were distinguished from juveniles. The study results indicate that there are changes in the Mediterranean gecko’s daily and seasonal activities. The relative population density of adult geckos is significantly higher than the relative population density of the juvenile ones. The relative density of allopatric adult population on Vis is significantly higher than the relative density of sympatric adult population on Hvar. Also, lower population densities of the Mediterranean gecko on Hvar are caused by the occurrence of the Moorish gecko (Tarentola mauritanica L.) in habitats where they live together, but also from different habitat conditions on that island which is obvious from lower population density on locations where the Mediterranean gecko is solely present.
