Quantifying interspecific and intraspecific diversity effects on ecosystem functioning

Rapid environmental changes result in massive biodiversity loss with detrimental consequences for the functioning of ecosystems. Recent studies suggest that intraspecific diversity can contribute to ecosystem functioning to an extent comparable to contributions of interspecific diversity. Knowledge of the relative importance of these two sources of biodiversity is essential for predicting ecosystem consequences of biodiversity loss and will aid prioritization of conservation targets and implementation of management measures. However, our quantitative insights into how interspecific and intraspecific biodiversity loss affects ecosystem functioning, and how the effects of these two sources of biodiversity loss on ecosystem functioning can be compared are still very limited. To facilitate this goal, we extend the interspecific Price partitioning method originally introduced by J. Fox in 2006, previously used to quantify species loss and gain effects on ecosystem functioning, to also accoun..., , , \#\# There are two data sets that are being used
1) Weider\_Size.txt: contains the body length of Daphnia genotypes of different species in 4 different food treatments
2) Weider2008Data contains the abundances of Daphnia genotypes

The data set consists of three columns
\*Clone: gives the different Daphnia genotypes (PX for pulex, PUL for pulicaria and HYB for hybrid species)
\*Treatment: gives the different food treatments (LH: low quality high quantity, LL: low quality low quantity, HL: high quality low quantity, HH: high quality high quantity)
\* Size: body length of Daphnia (mm)
