Abstract

How do nursery web spiders balance the costs of mating and foraging to maximize their reproductive success? Toft and Albo (2025) show that female Pisaura mirabilis demonstrate behavioral plasticity in mating strategies dependent on food availability. Females showed flexibility in mating numbers and aggressive behaviors based on hunger, resulting in equal reproductive outcomes. This study reveals an optimal mating strategy shaped by environmental stress, highlighting behavioral plasticity in nuptial gift-giving species and suggesting reproductive success under variable environmental conditions. Key Words: Behavioral plasticity, Pisaura mirabilis, nuptial gift-giving, optimal polyandry.

摘要：营养胁迫下幼蛛的行为可塑性保证了它们同等的繁殖成功率。

幼蛛如何平衡交配和觅食的成本，以最大限度地提高它们的繁殖成功率？Toft和Albo（2025）表明，雌性神奇Pisaura mirabilis在交配策略上表现出依赖于食物供应的行为可塑性。雌性在交配数量和基于饥饿的攻击行为上表现出灵活性，从而产生了平等的生殖结果。这项研究揭示了环境压力塑造的最优交配策略，突出了交配礼物物种的行为可塑性，并表明在可变环境条件下繁殖成功。
