山东宁阳早更新世哺乳动物化石(英文) 总被引:2,自引:2,他引:0
1999年,作者收到王元青博士转来胡长康老师未研究的一批哺乳动物化石。这些化石由山东省博物馆工作人员采自山东宁阳县伏山的裂隙堆积物中。根据化石围岩判断这批化石可归入同一动物群。该动物群包含12种:松鼠科1种(Sciurotamias sp.),兔科2种(Brevilagus brachypus,Lepus sp.),食肉目5种(Pachycrocuta perrieri,Nyctereutes sinensis,Canis variabilis, Homotherium sp.和Meles sp.),牛科2种(Gazella sp., Ovibovinae gen etsp.indet.),鹿科2种(Cervus sp.,Cervidae gen et sp.indet.)。其中,Pachycrocuta perrieri个体明显小于桑氏鬣狗(Pachycrocuta licenti),p2后附尖较发育,p4前附尖高,ml三角座窄。四川巫山原鉴定为桑氏鬣狗的标本中至少有一件下颌骨(重庆自然博物馆,CV877)应当归入此种。Meles sp.具有较周口店第18点发现的Meles chiai及中更新世常见的Meles mel? 相似文献

一般说来,从枝菌根(AM)真菌大多数是从植物根系根毛区(成熟区)侵入和扩展的,在显微镜下往往看不到根尖分生区和根冠表皮细胞被AM真菌侵染的特征。这就很容易给人们造成一种假象,似乎AM真菌不能侵染根尖分生区和根冠表皮细胞,即它们对AM真菌是免疫的。然而笔者多次于显微镜下看到AM真菌侵染根尖分生区和根冠表皮细胞,并形成典型的泡囊、丛枝、菌丝等结构。这一现象导致作者在温室盆栽和大田条件下研究了玫瑰红巨孢囊霉( Gigaspora rosea Nicol & Schenck)、珠状巨孢囊霉(Gigaspora margarita Becker & Hall)、根内球囊霉(Glomus omtraradices schenck & Smith、摩西球囊霉(Glomus mosseae (Nicol & Gerd.)
