Effect of Flexible Back on Energy Absorption during Landing in Cats： A Biomechanical Investigation

Cats are characterized by their excellent landing ability. During the landing, they extend and bend their flexible backs. This study was undertaken to examine the effect of flexible back on impact attenuation. We collected kinematic and ground reaction force data from cats performing self-initiated jump down at different heights. Based on these measurements, the mechanical energy and elastic back energy were calculated. Further, we derived a beam model to predict back stiffness from the morphology of the vertebral spines. We found that cat could actively modulate the bending level of flexible back and the landing angle at different heights, making some kinetic energy be stored briefly as elastic strain energy in the back. This mechanism allows cat to reduce the kinetic energy dissipated by limbs and improve the efficiency of energy absorption. These results can provide bio- logical inspiration for the design of a flexible spine on a landing robot, and we anticipated their use in the energy absorption equipments for planetary exploration.

寄生蜂对稻飞虱控害作用研究进展

稻飞虱(褐飞虱、白背飞虱和灰飞虱)近年来在亚洲地区连续大爆发，由次要害虫上升为主要害虫，给农业生产造成了重大的经济损失，严重威胁到世界粮食生产安全，寄生蜂作为稻飞虱的重要天敌，对其发生起着有效的自然控制作用。本文归纳整理了稻飞虱主要的寄生蜂种类及其优势种群的生物学、生态学特性，并重点总结了寄生蜂优势种群的寄生选择、种群消长影响因素以及它们的保护利用等，并对寄生蜂研究、保护、利用中存在的问题进行概括总结，旨在为稻飞虱的有效防控提供一定的参考价值。
