The spatial scaling of saprotrophic fungal beta diversity in decomposing leaves

Larry M. Feinstein, Christopher B. Blackwood
2013 Molecular Ecology

Does the skull carry a phylogenetic signal? Evolution and modularity in the guenons

ANDREA CARDINI, SARAH ELTON
2008 Biological Journal of the Linnean Society  
This finding, if confirmed in other groups, implies that the utility of specific FDMs for phylogenetic inference could, in many cases, be hampered by the low reproducibility of results.  ...  In the present study, we used computerized methods to 'dissect' the skulls of a primate clade, the guenons, into functional and developmental modules (FDM).  ...  To all of them, once more, we extend our deepest gratitude. This study was funded by a grant from The Leverhulme Trust.  ...
