Inside JEB i BOA CONSTRICTORS USE TWO STRATEGIES TO CLIMB

چکیده
Luring the snakes to climb the ropes by placing a dark cosy refuge at the top, Byrnes and Jayne filmed the animals’ ascents while measuring the tension on the rope as the animals coiled and uncoiled their grip. ‘All the climbing velocities were extremely slow,’ the duo says, ranging from 0.5 to 1 cm s–1 and the snakes only reached their top speeds on the thickest and tensest ropes. All of the snakes gripped the rope with some parts of their bodies as they translated other parts up, but Byrnes and Jayne noticed the animals used different movement patterns depending on whether they were scaling the thinner ropes (3 mm and 6 mm) or the thicker (9 mm) rope.

Perch size and structure have species-dependent effects on the arboreal locomotion of rat snakes and boa constrictors.
Arboreal habitats create diverse challenges for animal locomotion, but the numerical and phylogenetic diversity of snakes that climb trees suggest that their overall body plan is well suited for this task. Snakes have considerable diversity of axial anatomy, but the functional consequences of this diversity for arboreal locomotion are poorly understood because of the lack of comparative data. W...
متن کاملSubstrate diameter and compliance affect the gripping strategies and locomotor mode of climbing boa constrictors.
Arboreal habitats pose unique challenges for locomotion as a result of their narrow cylindrical surfaces and discontinuities between branches. Decreased diameter of branches increases compliance, which can pose additional challenges, including effects on stability and energy damping. However, the combined effects of substrate diameter and compliance are poorly understood for any animal. We quan...
متن کاملThe big squeeze: scaling of constriction pressure in two of the world's largest snakes, Python reticulatus and Python molurus bivittatus.
Snakes are important predators that have radiated throughout many ecosystems, and constriction was important in their radiation. Constrictors immobilize and kill prey by using body loops to exert pressure on their prey. Despite its importance, little is known about constriction performance or its full effects on prey. We studied the scaling of constriction performance in two species of giant py...

26 Inclusion body disease (IBD) is an infectious disease originally described in captive snakes. It has 27 traditionally been diagnosed by the presence of large eosinophilic cytoplasmic inclusions, and is 28 associated with neurological, gastrointestinal and lymphoproliferative disorders. Previously, we 29 identified and established a culture system for a novel lineage of arenaviruses isolated ...
