DOI: 10.1007/s00442-021-05083-7
Abstract: Understanding the direct and indirect effects of niche and neutral processes in structuring species diversity is particularly challenging because environmental factors are often geographically structured. Here, we used Structural Equation Modeling to quantify direct and… read more here.
