The structural equation model tested for direct effects of environmental heterogeneity on the contribution of diversity to variation in ecosystem functioning (that is, the diversity effect), as well as for indirect effects that were mediated by variation in species richness and species turnover. ...
---An equation for a straight line where log c = Y intercept and z = the slope of the line. Frank Preston: "The commonness and Rarity of Species" (1948) -The Lognormal Distribution-Suggested plotting species/abundance data on a geometric scale rather than a linear scale.-Grouped his dat...
In agreement with previous analyses, we find no support for the idea that differences in species richness are simply due to chance. However, contrary to most previous work, we also find no support for the hypotheses that high species richness is correlated with small body size and fast life ...

Both species richness (left graph below) and overall bird abundance (right graph below) were lowest in the vineyards without remnants nearby, and highest in remnants and in the surrounding matorral. Richness and abundance were very similar in remnants compared to the surrounding matorral. Species ...

We used GLMM with a negative binomial distribution, which deals with overdispersion in a Poisson distribution, to assess temporal trends in the richness of each pollination mode. Spatial structure was included in the model using the stochastic partial differential equation approach, as implemented by ...
