研究称圈养吸血蝙蝠被释放到野外后仍会维持其社交网络_我的网站

A |     科学家在《当前生物学》杂志上刚刚发表了一篇名为“在实验室中合作以及在野外维持社交网络的吸血蝙蝠”的研究论文。    Recent discoveries in Pompeii are revealing the lifestyle of the middle class in the ancient Roman city. Pompeii’s archaeological park announced its findings on Saturday. While much of the early studies of Pompeii were focused on the city’s elite, archeologists have increasingly become interested in the lives of the city’s middle and lower classes.,The excavation of a home or “domus” started in 2018 and is now paying dividends. The house had a courtyard with a well-adorned cistern or water tank, but other parts of the house show that the owner may not have had unlimited funds to decorate their house. One of the five rooms was left unpainted and with an earthen floor. Archeologists believe it may have been used for storage.,They also identified a bedroom with the remains of a bedframe and cloth from a pillow. The bedframe appeared identical to three cots found in a storage room that may have also served as sleeping quarters for enslaved people in the city.,Science & TechVideos: Archeologists Discover IKEA-Like Adjustable Beds in Ancient Roman City of Pompeii8 November 2021, 02:29 GMT,Another storeroom had built-in shelves and may have held dishes and cookware for a nearby kitchen. Archaeologists also discovered a storage trunk. While the trunk itself was damaged when the ceiling collapsed on it, they found a preserved oil lamp with carvings of the Greek god Zeus, called Iupiter by the Romans, transforming into an eagle.,"In the Roman empire, there was an ample chunk of the population that struggled with their social status and for whom 'daily bread,' was anything but a given,'' Gabriel Zuchtriegel, Pompeii’s archaeological park’s director said. "A vulnerable class during political crises and food shortages, but also ambitious about climbing the social ladder.",Archaeologists also found a fragment of what they believe was a translucent plate rimmed with emerald and cobalt blue and an intact incense burner shaped like a cradle.。他们对普通吸血蝙蝠（Desmodus rotundus）进行22个月的人工饲养及随后的追踪测试。该研究包括对从“大空心树”中选择的大约23只雌性吸血蝙蝠进行的测试，以及在野外的大约200只吸血蝙蝠。

B | 在收集上述蝙蝠的数据之前，科学家们记录了在野外栖息的蝙蝠之间的社交合作的观察结果。

C | 他们测量了每只蝙蝠与另一只蝙蝠之间的接近程度，并利用皮尔逊相关系数呈现结果。平均数显示了关联的三个要素：亲属关系（血缘关系），梳理行为和分享食物。一旦将蝙蝠释放到野外，研究人员就使用定制的高分辨率传感器对其进行跟踪。使用在所有这些时期收集的数据，研究人员表明，圈养的吸血蝙蝠之间的合作关系可以预测它们野外栖息地的距离。根据这项研究（以及以往的类似数据研究），“甚至在控制亲属关系的情况下”，食物共享和社交梳理行为也是相互关联和对称的。
