概括

年轻的切叶由于生物力学发达不够,不能食. 随着它们的成熟,它们的咬力和头囊强度显著增加,使得它们能够食并防止受伤.

科学领域:

昆虫的行为昆虫的行为
生物力学生物力学
进化生物学是进化的生物学.

背景情况:

社会昆虫表现出年龄多元化,年轻的工人留在巢里,年长的工人寻找食物.
驱动这种行为转变的确切机制,特别是身体限制,尚未完全理解.

研究的目的:

为了研究Atta vollenweideri切叶咬装置的生物机械发展.
为了确定是否有机械的局限性阻止了年轻的从寻找食物.

主要方法:

在Atta vollenweideri研究了咬牙器的生物机械发展.
在不同年龄的中测量了咬伤力,下关闭肌肉体积和头囊刚度.

主要成果:

成熟的采集者产生超过100mN的咬力,明显高于小牛.
大关闭肌肉的体积增加了六倍,头囊硬度随着年龄的增长而大幅增加.
年轻的缺乏必要的肌肉容量,并且拥有易变形的适应性头囊.

结论:

化后的生物机械发展对于切叶的食至关重要.
机械约束可能在社会昆虫中观察到的年龄多元化中发挥关键作用,这些社会昆虫需要苛刻的食任务.

关键词:

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
