| 實物特徵: | The rich-ness and abundance of aquatic plant communities were studied in 14 habitats of the Venezuelan “llanos” (07º35’-07º55’ N - 68º50’-69°00’ W, Apure) during an annual cycle. Annual means were 27ºC, 115 mm rainfall and 77% relative humidity. A permanent transect was set in each habitat (ten consecutive square meter quadrats from the shore to the water). The plants and the area they covered in each quadrat were recorded monthly for a year. The total richness was 69 species. Alatalo and Alatalo’s diversity analysis indicats that season, and its correlate, water level, influence species diversity and abundance more than habitat (spatial factor: geometric index-Euclidean distance). |
