In many crustacean species, an individual possesses both uniramous and biramous appendages that enable us to compare the two types on the same genetic background. Therefore, among the diverse morphologies of arthropod appendages, crustacean...
Cohesion depends on kinship but no permanent leadership in larval societies of a Neotropical butterfly [0.03%]

Accurate knowledge of a species' diets is fundamental to understand their ecological requirements. Next-generation sequencing technology has become a powerful and non-invasive tool for diet reconstruction through DNA metabarcoding. Here, we...
Female solitary bees flexibly change foraging behaviour according to their floral resource requirements and foraging experiences [0.03%]
雌性独居蜜蜂根据其植物资源需求和觅食经历灵活改变觅食行为
