摘要

在遇到潜在捕食者Elaphe quadrivirgata (a组)或同域非捕食者Eumeces latiscuatus (B组)或没有其他动物(C组)时,测量了速腹竹(Takydromus tachydromoides)的运动频率,作为静止倾向的指数。a组的运动频率显著低于B组和C组。在前10min内,速球绦虫的移动频率明显低于后10min。与没有经历过这种经历的动物相比,先前接触过四角蜥蜴的蜥蜴在随后的B阶段的运动频率显著降低。结果表明,大叶蝉的不动是一种自适应的反捕食行为,以避免被天敌发现

Spontaneous Immobility of the Japanese Lacertid Lizard, Takydromus tachydromoides
Frequencies of movement, as an index of propensity for immobility, of Takydromus tachydromoides were measured in the encounters with a potential predator Elaphe quadrivirgata (Session A) or a sympatric non-predator Eumeces latiscutatus (Session B), or in the absence of other animals (Session C). Frequency of movement in Session A was significantly lower than in Sessions B and C. In Session B, T. tachydromoides moved significantly less frequently during the first 10min than dur- ing the latter 10min. The lizards previously exposed to E. quadrivirgata reduced their movements in the subsequent Session B with significantly high frequency when com- pared with animals without such experience. It is suggested that immobility of T. tachydromoides is an adaptive antipredator behavior to avoid detection by a visually
