<p>The PhD research project focus on the study of evolution, adaptation, and speciation in<br />the subterranean environment using troglobitic Coleoptera of the genus Anthroherpon<br />as a model organism. Genus Anthroherpon belongs to the tribe Leptodirini (Coleoptera:<br />Leiodidae: Cholevinae), a group that has undergone extensive diversification in the<br />subterranean environment. All species of this genus have developed typical<br />troglomorphic modifications: complete anophthalmy, apterism, extreme elongation of<br />appendages, head, and pronotum, and physogastric elytra. To understand the<br />evolutionary history of this group, the troglomorphic adaptations need to be studied in<br />a phylogenetic framework. The thesis provide a comprehensive evolutionary analysis<br />of the Anthroherpon radiation, using a dated molecular phylogeny as a framework for<br />understanding Anthroherpon diversification, reconstructing the ancestral range, and<br />exploring troglomorphic diversity. In light of these findings, a new taxonomical<br />organisation of the group has been proposed.</p> / <p>Doktorska disertacija predstavlja studiju evolucije, adaptacije i specijacije u<br />podzemnim staništima troglobiontnih tvrdokrilaca roda <em>Anthroherpon</em>. Pomenuti rod<br />pripada tribusu Leptodirini (Leiodidae, Cholevinae), grupi koja je prošla intenzivnu<br />diverzifikaciju u uslovima podzemnih staništa. Sve vrste pomenutog roda poseduju<br />tipične troglomorfne osobine, kao što su: anoftalmija, apterizam, ekstremno izduženi<br />telesni nastavci, glava i pronotum, i fizogastrija. Radi razumevanja evolucione istorije<br />grupe, troglomorfne adaptacije su studirane u filogenetskom kontekstu. U analizi<br />evolutivne radijacije roda <em>Anthroherpon</em> korišćena je datirana molekularna filogenija<br />kao okvir za razumevanje diverzifikacije roda, evolucije troglomorfnih karaktera i<br />rekonstrukciju predačkog areala. U svetlu novih nalaza predložena je nova<br />taksonomska organizacija grupe.</p>
