MCQ - 8-11375

Western cousins the Timber rattlesnake may be especially vulnerable because of certain behaviors adapted for coping with the cold climate in which it lives.
Rattlesnakes are generally found in warm climates because, like all reptiles, they cannot generate or regulate their own body temperature internally and must rely on the sun’s warmth for heart. But Timber rattlesnake migrated into colder northern areas about 8,000 years ago when glaciers retreated. In these northern regions, the snakes developed a number of adaptive strategies to survive, but ultimately these behaviors make them more vulnerable to human predation, their main threat.
One survival strategy the snakes have developed is hibernation. For approximately eight months of the year, the rattlers remain motionless in deep frost-free crevices, with their body temperature dropping as low as 40 degrees. In the spring when they emerge, they must warm their chilled bodies by sunning for three or four days on rocks in the open. This behavior, coupled with the fact that Timber rattlesnakes tend to concentrate in large numbers at their wintering sites, make them eyes prey. Gestating females are particularly vulnerable because they spend much of their basking in the sun in order to produce live young from eggs. In addition, females have very long afterbirth intervals, producing live young only every three to five years. If a frost or cold spell comes late in the year, the entire litter of six to twelve young may die.
Efforts are underway to protect the Timber rattlesnake and it’s habitat from human depredation young may die.
