We consider partitioned linear models where the model matrix X = (X1 : X2) has full column rank, and concentrate on the special case where X 0 X2 = 0 when we say that the model is orthogonally partitioned.We assume that the underlying covariance matr

Biodiversity, or biological diversity, is “the variety of life on our planet, measurable as the variety within species, between species, and the variety of ecosystems” [12, 41] and the most widely applied index of biodiversity is surely Fisher's
