Ecologists, particularly those engaged in biogeomorphic studies, often seek to connect data from three or more domains. Using three-block partial least squares regression, we present a procedure to quantify and define bi-variance and tri-variance of data blocks related to plant communities, their soil parameters, and topography. Bi-variance indicates the total amount of covariation between these three domains taken in pairs, whereas tri-variance refers to the common variance shared by all domains. We characterized relationships among three domains (plant communities, soil properties, topography) for a salt marsh, four coastal dunes, and two temperate forests spanning several regions in the world. We …

South Africa has one of the most active civil societies in the world, with more than 85,000 registered civil society organizations (CSOs). However, the growth of CSOs in post-apartheid South Africa does not necessarily imply that the sector is strong. While it is true that the demise of the apartheid regime increased democratic representation within South Africa, CSOs have experienced a series of institutional challenges which have weakened their organizational stability. This has included increased oversight by the state, inefficient and inconsistent funding from government, fickle demands by private donors, and competition from other sectors. Through an in-depth case study …
