Effect size in ecological experiments: the application of biological models in meta-analysis

Article Abstract:

The use of meta-analysis to study biological models requires a common metric of effect size which has been defined as the difference between experimental and control treatments. Research was conducted on the effects of fish predation using two sets of data. Results showed that the approach posed potential problems and an ecologically based model is used as an alternative approach. The standardization of effect size in meta-analysis is a challenge that can be resolved through the specificity with which metrics can be defined.

Phosphorus distribution in three crustacean zooplankton species

Article Abstract:

Phosphorus (P) distribution has been studied in three crustacean zooplankton species to determine the proportion allocated to nucleic acids, phospholipids and other P compounds, as well as the distribution between somatic tissues and eggs and the implications for P fluxes in lakes. The species studied were Daphnia magna, Daphnia galeata and Eudiaptomus gracilis. The crustacean zooplankton exhibit low intraspecific variability in ratios of phosphorus to dry weight.
