Biodiversity & Plant Systematics

Biodiversity I have recently focussed on a number of issues relative to the discovery process of new species as informed decisions concerning global taxonomic priorities demand some understanding of how species are discovered and revised. We have shown: that on average there is a lag period of 35 years between collection and description of new species (see here); a very large proportion of type specimens are collected by a few 'big hitter' collectors i.e. 50% of all type specimens have been collected by 2% of collectors (see here). We have also explored, for flowering plants, why the increasing number of authors associated with species discovery do not reflect an increase in taxonomic capacity as has been claimed in recent literature. Most recently we have shown that more than 50% of the world’s natural history collections may not have a correct name (see here). Taxonomy & Foundation Monographs The aim of our Foundation Monograph approach is to accelerate the pace of taxonomic revisions of large problematic groups. The first two foundation monographs were published in 2015 on Convolvulus (see here) and Ipomoea in Bolivia (see here). Systematic theory Over the last few years I have focussed on conceptual issues of homology, deep homology and parallelism. Most recently I have returned to the issue of morphological data and phylogeny, showing that ‘phylogenetic trees do not reliably predict feature diversity’ (see here) and also re-visiting compatibility and character congruence as methods for analysing morphological data.
