Relative abundance of woody plants and their utilization by beavers (Castor canadensis) were measured on watersheds in Ashtabula and Columbiana Counties, Ohio, in 1966-67. A food index showed aspen (Populus sp.), alder (Alnus sp.), hop-hornbeam (Ostrya virginiana), black cherry (Prunus serotina), willow (Salix sp.)> dogwood (Cornus sp.) and oak (Quercus sp.) to be major foods; 20 different wood...

A new species of the family Lyctocoridae, Lyctocoris ichikawai Yamada & Yasunaga sp. nov., is described from Shikoku and Kyushu, southwestern Japan. The species was found to inhabit near the sap-exuding parts on the trunk of Sawtooth Oak, Quercus acutissima Carruth. (Fagaceae). Lyctocoris ichikawai is considered to be most closely related to L. zhangi Bu & Zheng, 2001 from continental China and...

The internal transcribed spacer (ITS) of ribosomal DNA has been used to confirm taxonomic classifications and define phylogenies in several plant species following sequencing or polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) techniques. In this study, co-dominant ITS PCR-RFLP molecular markers were produced in 30 Fagaceae individuals belonging to the Castanea, Fag...
