摘要

Acorns of the North European oaks (Quercus robur and Q. petraea) are an important food source for forest vertebrates in north-western Europe. This is not surprising because acorns are highly nutritious (Gurnell, 1993) and abundant. Seed production canamount to over 600 kg/ha or 60 acorns/m2 (Jones, 1959; Ovington and Murray, 1964; Tanton, 1965; Shaw, 1968a; Gurnell, 1993; Crawley and Long, 1995). Consumers of acorns in north-western Europe include mammals such as wild boar (Sus scrofd), roe deer (Capreolus capreolus), red deer (Cervus elaphus), rabbit (Oryctolagus cuniculus), hare (Lepus europaeus), bank vole (Clethriono-mys glareolus), wood mouse (Apodemus sylvaticus), yellow-necked mouse (A. flavicollis), red squirrel (Sciurus vulgaris) and the introduced grey squirrel (S. carol-inensis), and birds such as Eurasian jay (Garrulus glandarius), wood pigeon (Columba palumbus), crow (Corvus corone) and magpie (Pica pica) (Tanton, 1965; Corbet, 1974; Bossema, 1979; Kenward and Holm, 1993; Groot Bruinderink and Hazebroek, 1995; Gomez et al, 2003). The number of vertebrate species feeding on acorns is also large in other regions containing Quercus species .

Carol-Inensis)和欧亚杰伊(Garrulus Glandarius)等鸟类,木鸽(Columba Palumbus),Crow(Corvus Corone)和Magpie(Pica Pica)(1965年Tanton; Corbet,1974; Bossema,1979; Kenward和Holm,1993; Groot Bruinderink和Hazeboek,1995; Gomez等,2003 )。含有栎种类的其他地区,哺养橡子饲喂的脊椎动物种类的数量也很大。
