摘要

在其分布区的北部,阿伯特松鼠(Sciurus aberti)有两种颜色形态:野生型灰色形态和黑色形态。通过在美国科罗拉多州博尔德市及其附近使用相机诱捕器、公民科学数据和亲自观察,我们将目前的颜色形态频率与 1969-1971 年研究报告中的频率进行了比较。在所有研究地点,我们都观察到,与历史数据相比,黑色形态出现的频率大幅增加,且具有显著的统计学意义。我们推测,这种增加可能是由于在不断变化的森林环境中有利于黑色形态的选择。

Increase in the frequency of melanism in Abert’s Squirrel in Boulder, Colorado
In the northern portions of its range, Abert’s Squirrel (Sciurus aberti) has two color morphs: a wild-type gray morph and a melanistic morph. Using camera traps, citizen science data and in-person observations in and near Boulder, Colorado (USA), we compared current color morph frequencies to those reported in a 1969–1971 study. At all study sites, we observed a large and statistically significant increase in the frequency of the melanistic morph compared to historic data. We hypothesize that this increase may be due to selection favoring the melanistic morph in a changing forest environment.

期刊介绍: Mammalia is an international, multidisciplinary, bimonthly journal devoted to the inventory, analysis and interpretation of mammalian diversity. It publishes original results on all aspects of the systematics and biology of mammals with a strong focus on ecology, including biodiversity analyses, distribution habitats, diet, predator-prey relationships, competition, community analyses and conservation of mammals. The journal also accepts submissions on sub-fossil or recently extinct mammals.
