Spatial scaling laws and weight dependent distributions in guilds of Diptera and parasitic Hymenoptera
2001
Ulrich, W. (Nicholas Copernicus University, Torun (Poland). Dep. of Animal Ecology)
The paper tests the recent published synthetic theory of biodiversity of Ritchie and Olff (1999) using data on parasitic Hymenoptera and soil living Diptera. Neither the predicted size dependent size ratio patterns, nor the left skewed species number-size class ratios, nor right skewed species richness-productivity patterns were found. It is concluded that the basic assumptions of the theory is not applicable at fine scales and to guilds of higher trophic levels
