Question

Some fench scientests did
an experiment with Squirrel​

Answer 1

Abstract

The decline of the red squirrel (Sciurus vulgaris) in several European countries due to the introduction of the American grey squirrel (S. carolinensis) and the predicted arrival of the grey squirrel in France in the near future has lead to the development of a preventative conservation project in this country. In this study, we conducted an extensive survey of mitochondrial DNA variation in French red squirrels using a fragment of the mitochondrial D-loop and we compared the results with previously published data from other European populations.

Introduction

The red squirrel Sciurus vulgaris is a well-known animal found in many types of coniferous, deciduous and mixed forests of Eurasia [1]. It is a very widespread species, with a range extending from the British Isles in the west throughout the Palaearctic to Hokkaido Island in the east [1], [2]. The red squirrel is currently common throughout much of this range and is listed as “Least Concern” on the IUCN Red List [3]. However, it is of conservation concern in Britain, Ireland and, most recently, Italy, due to a combination of loss or fragmentation of its woodland habitat [4] and interspecific competition with the introduced North American S.
