摘要

为了弥补食物来源中矿物质的不足,许多有蹄类动物采用了各种方法,例如舔盐、摄取土壤以及啃食鹿角或骨头。啃食鹿角或骨头这种噬骨行为在鹿科动物中已有大量记载,但在梅花鹿(Cervus nippon)分布广泛的日本南部马笼岛,却只观察到梅花鹿有这种行为。本研究旨在对日本中部梅花鹿食骨症的观察结果进行初步说明。2018年7月9日和16日,在多摩川大学箱根自然森林部署了15个用于野生动物监测的相机陷阱,其中一个偶然捕捉到了成年雌性梅花鹿啃咬四梢鹿角的多次事件。这些事件的发生恰逢梅花鹿的产仔季节,而在产仔季节,食物中的矿物质普遍缺乏,这表明噬骨症是对日本中部梅花鹿食物中营养缺乏的一种反应。因此,由于缺乏在其他地区进行的梅花鹿食骨症研究,系统调查可能会为梅花鹿在不同地理区域的这种行为提供更多证据。与文章相关的数字视频图像可在 http://www.momo-p.com/showdetail-e.php?movieid=momo240508cn01a 网站上获取。

Video evidence of unusual antler-gnawing behavior of sika deer (Cervus nippon) in central Japan

Video evidence of unusual antler-gnawing behavior of sika deer (Cervus nippon) in central Japan

To compensate for mineral deficiencies in food sources, numerous ungulate species use various methods, such as salt licking, soil ingestion, and gnawing on antlers or bones. While osteophagia, the act of gnawing on antlers or bones, is well-documented in cervid species, it has only been observed in sika deer (Cervus nippon) on Mageshima Island in southern Japan despite their widespread distribution. This study aimed to provide an initial account of the observations of osteophagia in sika deer from central Japan. One of the 15 camera traps deployed in the Hakone Nature Forest of Tamagawa University for wildlife monitoring serendipitously captured multiple instances of adult female sika deer gnawing on a four-tined antler on July 9th and 16th in 2018. These occurrences coincided with the fawning season of the species during which mineral deficiencies in the diet are prevalent, suggesting that osteophagia serves as a response to nutrient deficiencies in the diet of sika deer in central Japan. Thus, systematic surveys may yield additional evidence of this behavior in sika deer across diverse geographical areas given the absence of studies on osteophagia in sika deer conducted in other regions. Digital video images related to the article are available at http://www.momo-p.com/showdetail-e.php?movieid=momo240508cn01a.

期刊介绍: The Journal of Ethology features reviews and original papers relating to all aspects of animal behavior, including traditional ethology. Papers on field, laboratory, or theoretical studies are welcomed. In contrast to many other ethological journals that prefer studies testing explicit hypotheses, the Journal of Ethology is interested both in observational studies and in experimental studies. However, the authors of observational studies are always requested to provide background information about behaviors in their study and an appropriate context to establish the scientific importance of their observation, which in turn produces fascinating hypotheses to explain the behaviors.
