摘要

研究人员于2021年4月28日在伊利诺伊州北部的沼泽沼泽中发现了一只成年雌性布兰丁龟的粪便中含有哺乳动物毛发。通过对护毛长度、近端干型和护毛区横截面的比较分析，表明该护毛属于一种麝鼠。这是第一次记录到布兰丁鳖的哺乳动物食物，也是第二次在该地点记录到布兰丁鳖的饮食中有新的猎物。鉴于这一发现，我们建议有必要对这种海龟进行额外的饮食研究。

First Evidence of Muskrat (Ondatra zibethicus) in the Diet of the Blanding's Turtle (Emydoidea blandingii)

Abstract We discovered mammalian hair in the feces of an adult female Emydoidea blandingii (Blanding's Turtle) in a palustrine marsh in northern Illinois on 28 April 2021. Comparison and analysis of guard-hair length, proximal shaft pattern, and cross section of the shield region revealed the hair to be that of an Ondatra zibethicus (Muskrat). This is the first recorded mammalian food item of a Blanding's Turtle and is the second time a novel prey item has been documented in the diet of a Blanding's Turtle at this site. In light of this discovery, we suggest a need for additional diet studies on this turtle.

期刊介绍： The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion. The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
