摘要: Although in recent years behavioral syndromes have received a wealth of attention, how traits within respond to changing environments is not well resolved. Here, we test the effects temperature on suite spider Anelosimus studiosus determine (1) whether there are shifts individuals’ social tendency, activity level, and foraging behavior response temperature, (2) if these shift direction predicted by within-population axes trait covariance, (3) differ among individuals. In previous work, documented syndrome A. where increased tolerance conspecifics correlated with decreased level aggressiveness toward prey. Furthermore, distinct among-population differences behavior, individuals from warm sites tend be more aggressive active than cold sites. Our data here reveal that at warmer temperatures exhibit diminished conspecifics, levels, shorter latencies attack, tendencies attack multiple prey items. found individual were consistent across regimes for majority considered here: latency attack. These findings hypothesis behaviors linked together shared genetic underpinnings (e.g., metabolic differences) non-independently contemporary abiotic environment (i.e., temperature). our suggest itself could responsible variation structure studiosus.
