中文摘要 | 為探討鳥類豐富度和棲地指標(FSA, FSD和FHD)之關聯,吾人研究其主要食物(昆蟲)和上述指標之關係。初步結果顯示同屬針葉林的松和雲杉林的昆蟲相組成較類似。而柳林由於FSA和FHD值較大,故昆蟲相較為豐富;由昆蟲和棲地因子之相關性可以說明鳥類反應其漆地正如其食物(昆蟲)亦然。 |
英文摘要 | I examined the insect/habitat relationships in the dune forest northwestern coast, California, in order to gain an insight into the bird/habitat relationships. Twenty buckets were set in representative of 3 habitat types-Willows (Salix spp), Spruce (Picea sp), and Lodgepole pine (Pinus contorta). Spruce and Lodgepine stand are more similar in insect fauna. Willow stand is the highest in FSA and- FHT, and thus most abundant in insect communities. FAS (<2m) and FHD are significantly correlated with insect communities but for FSD, which explain why FSD is a poor indicator of bird communities. |
