Estimating Competition Coefficients from Census Data: A Test with Field Manipulations of Tidepool Fishes

摘要: Interaction coefficients between species have been estimated using both static regression models (from a single census) and dynamic (incorporating population change through time). However, the output of these varied has not compared with results experimental manipulations within same system. Using guild tidepool sculpins, I tested whether competition obtained from were consistent manipulations. Field revealed competitive effect Oligocottus maculosus on Clinocottus globiceps growth no C. O. growth. The result most closely matched experiments. Static models, in contrast, less results, sometimes even predicting interactions different sign those show that inconsistency model...
