Abstract

The adaptive value of fluorescence among the vertebrates has been studied most in fishes and birds, and only a few observations have been published regarding fluorescence in the pelage of mammals. Recently, reports of fluorescence in some marsupials, the platypus, and in flying squirrels have become available. We report the occurrence of fluorescent properties in some mammals from Arkansas. Most carnivores, bats, and rodents did not exhibit the property when viewed under UV light. However, opossums, rabbits, a weasel, muskrats, and moles showed substantial UV response, and a few other mammals showed minor fluorescence. Colors fluoresced included pink, green, and light cyan. Most species exhibited only 1 color, but the opossum responded with 2 colors. Potential explanations for positive responses to UV light include species signaling, mate assessment, predator avoidance, or prey location. Alternatively, the response may be an artifact without adaptive significance.
阿肯色州部分哺乳动物的荧光研究
荧光在脊椎动物中的适应价值研究最多的是鱼类和鸟类,而关于荧光在哺乳动物皮毛中的观察报告很少。最近,在一些有袋类动物、鸭嘴兽和鼯鼠身上发现了荧光。我们报告了在阿肯色州的一些哺乳动物中出现的荧光特性。大多数食肉动物、蝙蝠和啮齿动物在紫外线下观察时没有表现出这种特性。然而,负鼠、兔子、鼬鼠、麝鼠和鼹鼠表现出明显的紫外线反应,其他一些哺乳动物表现出轻微的荧光。荧光的颜色包括粉色、绿色和淡青色。大多数物种只表现出一种颜色,而负鼠则表现出两种颜色。对紫外线积极反应的潜在解释包括物种信号、配偶评估、捕食者躲避或猎物定位。或者,响应可能是没有自适应意义的工件。
