Historical Biogeography and Diversification of Truffles in the Tuberaceae and Their Newly Identified Southern Hemisphere Sister Lineage
Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes species with socio-economic importance...
متن کاملEcological and Historical Factors in Fern Biogeography
Remarkable diversity in recognized endemic centres as well as noteworthy disjunct distributions have led students of the pteridophytes to seek historical explanations for these phenomena. A suite of distinctive attributes limit the array of possible explanations: most biogeographically significant are ( I ) the smaller number of species-range determinants, and (2) the substantial capacity for l...

A comparison of clustering methods for biogeography with fossil datasets
Cluster analysis is one of the most commonly used methods in palaeoecological studies, particularly in studies investigating biogeographic patterns. Although a number of different clustering methods are widely used, the approach and underlying assumptions of many of these methods are quite different. For example, methods may be hierarchical or non-hierarchical in their approaches, and may use E...
