Abstract

Termofilni mravi roda Cataglyphis nastanjuju pustinje i polupustinje Palearktika koje pripadaju najtoplijim i najsušim staništima na Zemlji. Zahvaljujući brojnim morfološkim i fiziološkim prilagodbama te prilagodbama ponašanja najaktivniji su za vrijeme najtoplijeg dijela dana izbjegavajući time predatore i kompeticiju. Sve vrste su strvinari koji se hrane organizmima uginulim od vrućine. Radilice Cataglyphis mrava u potragu za hranom odlaze samostalno, prelazeći velike udaljenosti, a zatim se bez pogreške vraćaju u mravinjak najkraćim mogućim putem zahvaljujući iznimno razvijenom sustavu navigacije. Cilj ovog rada je dati pregled prilagodbi mrava roda Cataglyphis na život u suhim i vrućim uvjetima, s naglaskom na traženje hrane i navigaciju.

Abstract (english)

The thermophilic ant genus Cataglyphis inhabits the arid and semiarid regions of the Palearctic, which are among the hottest and driest habitats on Earth. Thanks to numerous morphological, physiological and behavioral adaptations, these ants are most active during the hottest part of the day, thus avoiding predators and competition. All species are scavengers and feed on organisms that have died from the heat. Cataglyphis workers travel long foraging distances on their own and then return straight back to the nest, without getting lost and by the shortest possible route, thanks to an incredibly developed navigation system. This paper provides an overview of the adaptations of the ant genus Cataglyphis to life in dry and hot environments, focusing on foraging and navigation.
