摘要 | Animals' morphology and locomotion are finely tuned to their specific habitats. For example, grass-living lizards often have reduced limbs, elongated bodies, and remarkably long tails, which can potentially aid them in moving through dense vegetation. Despite previous research demonstrating the role of tails in lizard locomotion through autotomy experiments, their specific effects within their natural habitats remains largely unexplored. We investigated how tails influence the locomotion of green-spotted grass lizards (Takydromus viridipunctatus) by observing their runs before and after tail loss on tracks with and without grass-like obstacles. Using various kinematic parameters extracted from video recordings, we analyzed the associations among these parameters and assessed the joint impact of tails and the grassland environment on lizard locomotion. The results revealed significant reductions in maximal distance, stride length, sprint speed, body angle, and pause number following tail loss, while stride frequency and tail angle remained unaffected. Moreover, we observed a substantial increase in pause frequency on tracks with grass-like obstacles for tailless lizards, emphasizing the critical role of long tails in facilitating grass lizard locomotion within grassland environments. This study provides a comprehensive evaluation of the impact of a long tail on grass lizard locomotor capabilities, offering insights into the interplay between various locomotor parameters. Crucially, it highlights a synergistic effect between the tail and the grassland habitat on locomotion, strongly suggesting that a long tail contributes significantly to their adaptation to grassland habitats at a biomechanical level. |
