摘要

阿特拉克斯是一种标志性的澳大利亚蜘蛛,因为它的毒液对人类来说是致命的。此外,一些毒液生物分子有希望作为治疗和生物杀虫先导物。然而,与该物种的生活史和行为有关的方面,可能会影响毒液成分的变化,一直被忽视。我们评估了不同环境(捕食、同种耐受性和探索新领地)和刺激(空气和刺激)下幼鱼和成年雌鱼的不同行为特征(反捕食者行为、防御和活动)。成年鱼对空气的反应比幼鱼快,但对刺激的反应,随着时间的推移,幼鱼和成年鱼都变得更具防御性。在同种耐受性和探索性方面,成虫和幼虫没有差异。了解有毒物种的行为是很重要的,因为行为可能会影响生理特征,比如毒液,以及蜘蛛适应不同条件的能力。

Behaviour of the Sydney funnel-web spider Atrax robustus over different contexts, time, and stimuli

Atrax robustus is an iconic Australian spider because the venom can be lethal to humans. Moreover, some of the venom biomolecules have promise as therapeutic and bioinsecticidal leads. Nonetheless, aspects related to the life history and behaviour of this species, which might influence changes in venom components, have been overlooked. We assessed different behavioural traits (antipredator behaviour, defensiveness and activity) of juveniles and adult females across different contexts (predation, conspecific tolerance and exploration of a new territory) and stimuli (puff of air versus prod) over time. Adults responded to a puff of air faster than juveniles, but in response to a prod, both juveniles and adults become more defensive over time. No differences were observed between adults and juveniles for conspecific tolerance and exploration. Understanding behaviour of venomous species is important because behaviours may affect physiological traits, such as venom, and the ability of spiders to adapt to different conditions.
