Species abundance patterns and the structure of ground-beetle communities

The total 4-yr carabid catch in pitfalls was a good predictor of mean biomass, and was used as a measure of the quantitative importance of species. The first premise of causal models (the quantitative importance of species should be closely correlated with their niche breadth) was valid for the dominant species only. This was also the case for the second premise (dominance relations are governed by competition). -from AuthorSCOPUS: NotDefined.j
