20.500.12556/DKUM-63902 Vpliv temperature na pigmentacijo in velikost telesa larv volkca vrste Euroleon nostras Effect of temperature on pigmentation and body size of antlion larvae Euroleon nostras Spreminjajoče se okolje vpliva na osebke, ki v njem živijo. Temperatura je eden izmed ključnih dejavnikov, ki je za organizme pomemben in v okolju tudi zelo spreminjajoč. Temperatura vpliva na biokemične in fiziološke procese v organizmih. Vpliv temperature je še posebej pomemben pri eksotermnih organizmih, katerih telesna temperatura je odvisna od temperature okolice. V magistrski nalogi smo želeli preveriti vpliv temperature na velikost in pigmentiranost telesa ter razvoj in aktivnost larv vrste E. nostras. Ugotovili smo, da so larve prvega in drugega larvalnega stadija aktivne najdlje časa, kar pomeni, da so čez zimo v mirovanju najkrajši čas, medtem ko so larve tretjega larvalnega stadija v diapavzi najdaljši čas. Ugotovili smo, da se kaže počasnejši razvoj larv, ki smo jih gojili pri nižjih temperaturah v primerjavi z larvami gojenimi pri višjih temperaturah. Prav tako so se pokazale razlike v pigmentaciji larv. Larve gojene pri nižjih temperaturah so imele dorzalno stran glave in protoraksa temnejše obarvane kot larve gojene pri višjih temperaturah. A changing environment affects all organisms that lives within it. Environmental temperature is one of the key factors important to organisms, while also being quite variable. It affects the biochemical and physiological processes in living organisms. The effect of temperature is most noticeable in ectothermic organisms, whose body temperature depends on the temperature of their environment. In this Master's thesis we investigated the effect of temperature on the body size, pigmentation, development and activity of E. nostras larvae. We found that first and second instar larvae were active for the longest amount of time, which means that their winter period of inactivity was the shortest, while the third instar larvae remained in diapause for the longest period. The results also indicate that larvae reared at lower temperatures exhibited a slower rate of development than larvae reared at the higher temperature. There were also noticeable differences in larvae's pigmentation. Larvae reared in the cooler temperature regime had darker coloration on the dorsal side of the head and prothorax in comparison to larvae reared in higher temperature regime.
