The role of social experience in eavesdropping by male wolf spiders (Lycosidae)

摘要: When reproductive success is limited by mate search costs, males can reduce costs eavesdropping and initiating displays if conspecific courtship detected. Here, we examine male Schizocosa ocreata wolf spiders, with field studies, laboratory studies using video playback live exposure studies. In enclosure experiments, introduced responded increased signalling behaviour in the presence of a courting male. laboratory, field-collected spent more time engaged interaction behaviours performed bouts activity response to stimulus than did laboratory-reared males, suggesting that might arise as consequence experience. To explore this further, conducted associative learning on naive, pairing sensory cues indicating female presence. Results showed no prior learned associate other females. subsequent recognized differences behaviour, responding often for longer periods stimuli spiders walking or an empty leaf litter background (no spider). Additional significantly when presented two three simultaneously. Together, these findings confirm meet assumptions suggest social experience arising from interactions conspecifics may impact behaviour.
