概括

狼蜘蛛母对于幼的出现至关重要,而不仅仅是化. 母亲根据环境风险 (如阳光照射,洪水和掠食) 灵活调整卵囊管理和逃生速度.

科学领域:

行为生态学行为生态学
进化生物学进化生物学
动物行为动物行为

背景情况:

卵袋繁殖是蜘蛛中一个昂贵的母性策略.
后代的好处和母亲的策略是其进化持久性的关键.

研究的目的:

调查母亲在狼蜘蛛小的出现中的作用.
要确定卵囊开放是否是对胚胎线索的灵活反应.
为了检查狼蜘蛛母亲如何在生态风险下调整移动.

主要方法:

研究了狼蜘蛛 (Pardosa pusiola) 与同物种和跨物种的养母.
观察到与胚胎发育相关的卵囊开放时间.
在模拟阳光照射,洪水和掠食风险下评估母亲的运动运动性能.

主要成果:

母亲的存在对于幼的出现至关重要,而不是化本身.
同种类的寄养母亲同步打开卵囊;跨种类的寄养母亲没有.
母亲根据风险调节逃生速度:在中度阳光下慢,在高阳光/掠食下快,在洪水下没有变化.

结论:

狼蜘蛛母体表现出灵活的卵囊管理和适应性运动,以应对环境风险.
昂贵的家长照顾可以通过父母的适应性行为调整来进化地维持.

关键词:

Fixed Action Patterns

Fixed Action Patterns

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
