The biotic and abiotic factors of an ecosystem exert an influence on the behavior and survival of organisms, which adapt to changes in these factors to ensure their reproduction and survival. Phenotypic plasticity regards any type of change induced by the environment without the need for genetic modifications. The aim of the present study was to evaluate whether the investment of the antlion, Myrmeleon brasiliensis (Neuroptera, Myrmeleontidae) in trap building is a phenotypic response that changes according to the surrounding environment. Larvae were observed in their natural environment (control), in a simulated natural environment (below tents) and after being transplanted to the laboratory. We found that the investment in trap size is a plastic phenotypic response in M. brasiliensis larvae and this behavior varies in accordance with the location in which the larvae build their traps. In areas with protection for the traps, greater investment was made in the size of the trap and consequently increased the success in capturing prey.

蚁狮幼虫 Myrmeleon brasiliensis (Neuroptera, Myrmeleontidae) 觅食行为的可塑性

生态系统的生物和非生物因素对生物的行为和生存产生影响,生物适应这些因素的变化以确保其繁殖和生存。表型可塑性涉及环境引起的任何类型的变化,而无需进行遗传修饰。本研究的目的是评估蚁狮Myrmeleon brasiliensis(Neuroptera,Myrmeleontidae)在陷阱建造中的投入是否是一种根据周围环境而变化的表型反应。在自然环境(对照)、模拟自然环境(帐篷下方)和移植到实验室后观察幼虫。我们发现对陷阱大小的投资是M. brasiliensis的可塑性表型响应幼虫,这种行为根据幼虫建立陷阱的位置而变化。在有陷阱保护的地区,对陷阱的大小进行了更大的投资,从而提高了捕获猎物的成功率。
