Martin.9904282This exploratory research investigates the possibility that ring structures in bat and rodent bones may provide climatic information. Long bone segments in modern animals that hibernate and those that do not will be embedded, sectioned, and examined under a scanning electron microscope. Theoretically, there should be differences in skeletal morphology represented by these behavioral differences. If successful, this approach can be used to explore the physiological strategies of ancient mammals, perhaps identifying the earliest fossil evidence for torpor in many mammalian groups. Ring structures could also be used to infer climatic changes during the Pleistocene, perhaps consistent with interglacial and glacial cycles.

Martin.9904282这项探索性研究调查了蝙蝠和啮齿动物骨骼中的环形结构可能提供气候信息的可能性。现代动物冬眠和不冬眠的长骨段将被嵌入、切片并在扫描电子显微镜下检查。 理论上，这些行为差异所代表的骨骼形态应该存在差异。 如果成功，这种方法可用于探索古代哺乳动物的生理策略，或许可以识别许多哺乳动物群体中最早的麻木化石证据。 环结构也可用于推断更新世期间的气候变化，也许与间冰期和冰期循环一致。
