摘要

作者:Tyler-Julian, Kara;查普曼，凯特·M;弗朗西丝,坎迪斯;摘要:通过对123只野生海牛和16只圈养海牛肢体(左右鳍)使用情况的观察，研究了佛罗里达海牛(Trichechus manatus latirostris)的侧边偏好。我们还分析了野生海牛的档案数据，以建立船舶引起的身体疤痕指数，以确定规避行为的偏侧性。野生和圈养海牛在个体水平上表现出鳍侧化，而在群体水平上表现出鳍侧化，包括触底、划水和进食等行为。相比之下，海牛在种群水平上的船疤痕偏倚是偏侧的，更多的海牛表现为左侧疤痕偏倚(45%)，而不是右侧疤痕偏倚(34%)或背部疤痕偏倚(21%)。

Behavioral lateralization in the Florida manatee (Trichechus manatus latirostris)

Author(s): Tyler-Julian, Kara; Chapman, Kate M; Frances, Candice; Bauer, Gordon B | Abstract: We examined side preferences in the Florida manatee (Trichechus manatus latirostris) through observations of limb use (right and left flipper) in 123 wild and 16 captive individuals. We also analyzed archival data on wild manatees to develop an index of boat-caused body scars to determine lateralization of evasive action. Wild and captive manatees displayed flipper lateralization at the individual, but not the population level for several behaviors including substrate touches, sculling, and feeding. In contrast, manatees were lateralized at the population level for boat-scar biases with more manatees showing a left scar bias (45%) versus right (34%) or dorsal (21%).
