20.500.12556/DKUM-64831 PLENILSKO VEDENJE LARV DVEH VRST VOLKCEV V RAZLIČNIH RAZMERAH PREDATORY BEHAVIOUR OF TWO ANTLION SPECIES IN DIFFERENT CONDITIONS V magistrskem delu smo obravnavali vedenjsko plastičnost pri larvah dveh vrst volkcev (Neuroleon microstenus in Euroleon nostras) in preverili konsistentnost obnašanja pri posamezniku. Ugotovili smo, da so larve vrste N. microstenus oba vedenjska vzorca odstranjevanja ostankov plena v povprečju uporabljale enako pogosto. Proučevali smo vedenjsko plastičnost volkcev vrste N. microstenus in ugotovili, da se vedenjski vzorci v razmerah z apliciranim vidnim dražljajem, v razmerah z manjšo granulacijo substrata in v razmerah, kjer smo larve hranili z manjšim plenom, razlikujejo od vedenjskih vzorcev v kontrolnem poskusu. Pri volkcih vrste N. microstenus smo zabeležili 12 osnovnih vedenjskih vzorcev, ki so v različnih razmerah bili različno zastopani, kar kaže na vedenjsko plastičnost vrste. Pri vrsti E. nostras pa smo zabeležili 9 različnih osnovnih vedenjskih vzorcev, ki so zaradi vedenjske plastičnosti prav tako različno zastopani v različnih razmerah (kontrola, vidni dražljaj in vibracijski dražljaj). Zanimiva sta dva na novo opisana vedenjska vzorca - obmirovanje med dražljajem in priprava mesta prežanja. Povprečen čas hranjenja larv je bil najkrajši v kontrolnem poskusu, podaljšal se je z vidnim dražljajem in spremembo granulacije. Naše raziskave niso potrdile, da bi manjši plen vplival na čas prehranjevanja larve. Rezultati statističnih analiz signifikantnih razlik ne potrjujejo. In this master thesis we studied the behavioural plasticity of larvae in two different species of antlions (Neuroleon microstenus and Euroleon nostras) and verified the consistency of specific behaviours in individuals. We discovered that in N. microstenus larvae both behavioural patterns of removing prey remains were used with about the same frequency. We studied the behavioural plasticity in individual N. microstenus larvae and discovered that behavioural patterns in specific circumstances such as application of visual stimuli, smaller granulation of the substrate and smaller prey size, vary from the behaviours observed in the control group. In N. microstenus we recorded 12 behavioural patterns which varied in frequency when different circumstances occurred, thus pointing to the presence of behavioural plasticity in the species. In E. nostras larvae 9 different behavioural patterns were recorded which were also represented with variable frequency depending on which circumstances occurred (control group, visual stimuli, and vibrational stimuli). Additionaly, two newly described behavioural patterns were recorded – quiescence during stimuli and the preparation of the ambush position. The average feeding time of the larvae was shortest in the control group and was prolonged with the application of visual stimuli and the change in substrate granulation. Our research did not confirm the theory that smaller prey has an effect on the duration of the feeding. Statistical analysis results did not point to significant differences. volkci lijakarji nelijakarji Neuroleon microstenus Euroleon nostras vedenjska plastičnost vidni dražljaj vibracijski dražljaj sprememba granulacije velikost plena antlions pit-builder non-pit-builder Neuroleon microstenus Euroleon nostras behavioural plasticity visual stimuli vibrational stimuli change in granulation prey size true true false [J.
