By using documents handed in by local peasants for permission to use guns to counter agricultural damage by wildlife and records of deer hunting, the distribution of sika deer (Cervus nippon) around the Kanto plain during Edo era was demonstrated. As a result of the analysis of 540 historical documents, (1) agricultural damage was shown to have been caused by sika deer and boar, which were driven from fields all the time, (2) agricultural damage existed in lowlands, tablelands and hills, and happened only at fields, not in forestry regions, (3) complaints to agricultural damage was concentrated especially in the "takaba" regions, (4) agricultural damage occurred continuously through out the Edo era at each place. The similarity between land-use of the area where the documents continuously existed and that of the outskirts on the area suggests that sika lived everywhere at that time.

This paper describes a study of the spatial structure and gap dynamics of a beech forest affected by the overbrowsing by sika deer (Cervus nippon) in the eastern part of the Tanzawa mountain zone of Kanagawa Prefecture. Beech (Fagus crenata), walnut (Pterocarya rhoifolia), linden (Tilia japonica) and fir (Abies homolepis) dominate the canopy layer of the forest, but the shrub layer is dominated by epaullete trees (Pterostyrax hispidata), which are pioneer plants and unpalatable for sika deer. All seedlings except these are subject to great stress caused by sika deer overbrowsing. It assumed that epaullete trees invade and grow rapidly in many gaps in the beech forest, without competition from other species. On the other hand, seedlings of other species grow normally in areas protected by fence. In conclusion, control of the sika deer population is required for normal regeneration of the beech forest.

The authors studied the likelihood that seeds were being dispersed by the Japanese black bear (Ursus thibetanus japonicus) in a deciduous forest near Ashikawa Village, Yamanashi Prefecture. The forest was composed of 113 tree species. Japanese black bear ate fruits and seeds belonging to 37 species (including 7 unidentified). About 86.7 to 99.7% of seeds identified in 360 samples of bear feces were in good condition for 17 species (10 drupes, 5 berries, 1 multiple fruit of droplets and 1 pome). However, no intact seeds were found for 5 nut species. The germination rate of Yamasakura (Prunus jamasakura) seeds taken from feces was the same as for uneaten seeds. The results of this investigation suggest a high likelihood of seed dispersal by the Japanese black bear.

ツキノワグマの糞に飛来する食糞性コガネムシ (以下糞虫) を山梨県芦川村および東京都奥多摩町で調査した。18種が確認された。いずれも広域に分布し, 他の動物の糞でも確認されている種であった。種により季節消長は異なり, 5種は春から秋にかけて成虫が出現したが, 13種は特定の季節のみ成虫の出現が確認された。日周消長は, トラップで採集された10種のうち5種は昼間中心に, 4種は夜間中心に飛来する種, 1種は季節的に活動時間帯が変化する種であった。糞虫の活動場所は, 8種はdwellerで, 糞の表面および糞の内部でのみ確認された。10種はtunnellerで, 糞下部の土壌内からも糞とともに確認された。Tunnellerは, 産卵期以外も, 糞とともに土壌内から確認された。ツキノワグマの糞に数多く飛来した, コブマルエンマコガネ, クロマルエンマコガネ, マエカドコエンマコガネはいずれも, 昼間中心に飛来し, tunnellerタイプの糞虫であった。
