Abstract

Slatkovodni rakovi vrlo su pogodni modeli za istraživanje agonističkog ponašanja. Agonističko ponašanje je ponašanje koje uključuje agresivnost, obranu i izbjegavanje borbe. Slatkovodni rakovi agresivne su životinje, a njihove česte borbe igraju važnu ulogu u formiranju njihove društvene strukture. Rakovi se međusobno bore za resurse kao što su hrana, sklonište i partneri, koji su im potrebni za uspješan rast, preživljavanje i reprodukciju. U ovom radu ukratko je opisano agonističko ponašanje slatkovodnih rakova te faktori koji na njega utječu. U određivanju ishoda borbe ulogu imaju razni vanjski i unutarnji faktori te iskustva raka u prošlim borbama iz kojih izlaze kao pobjednici (efekt pobjednika) ili gubitnici (efekt gubitnika). Borbe mogu biti različitih intenziteta, a svaka rezultira pobjednikom (dominantni rak) i gubitnikom (podređeni rak). Nizom borbi formira se linearna hijerarhija dominacije, na čijem je vrhu alfa rak.

Abstract (english)

Freshwater crayfish are very suitable models in studying agonistic behaviour. Agonistic behaviour is a type of behaviour which involves aggression, defence and avoiding fights. Crayfish are aggressive animals and their frequent fights play an important role in formation of their social structure. Crayfish fight each other to gain resources such as food, shelter and mates, which they need for successful growth, survival and reproduction. In this work, agonistic behaviour has been shortly described, along with the factors that affect it. Various intrinsic and extrinsic factors define the battle outcome as well as experience gained in previous fights (known as the winner effect and the loser effect). Fights are characterised by different intensities and each of them generates the dominant crayfish and its subordinate. The alpha crayfish is on the top of the linear dominance hierarchy, created by a series of battles.
