Solving a novel confinement problem by spartaeine salticids that are predisposed to solve problems in the context of predation.

摘要: Intricate predatory strategies are widespread in the salticid subfamily Spartaeinae. The hypothesis we consider here is that spartaeine species proficient at solving prey-capture problems also novel problems. We used nine from this our experiments. Eight of these (two Brettus, one Cocalus, three Cyrba, two Portia) known for specialized invasion other spiders’ webs and actively choosing spiders as preferred prey (‘araneophagy’). Except use trial error to derive web-based signals with which they gain dynamic fine control resident spider’s behaviour (‘aggressive mimicry’).The ninth species, Paracyrba wanlessi, not araneophagic instead specializes preying on mosquitoes. presented a confinement problem could be solved by error. test spider began each an island tray water, atoll surrounding island. From island, choose between potential escape tactics (leap or swim), but decided random before tactic would fail achieve partial success. Our findings show seven aggressive-mimic repeating ‘correct’ choices switching alternative after making ‘incorrect’ choice. However, predicted, there was no evidence C. gibbosus P. non-aggressive-mimic problem. discuss context often-made distinction domain-specific domain-general cognition.
