Hasenjager and Dugatkin 2016 Mixed Focal Follows

Focal follows were conducted on each fish in a group on three separate occasions. Focal follows lasted for four minutes, during which the nearest neighbor of the focal individual was recorded every ten seconds. An X indicates that no individuals were within four body lengths of the focal individual at that time.

本研究针对鱼群中的每一条个体，在三个独立的观测时段开展了焦点个体追踪观测（focal follow）。每次观测持续四分钟，期间每十秒记录一次目标个体的最近邻个体。若记录值为"X"，则代表该时刻无任何个体处于目标个体的4倍体长范围内。
