TL;DR: The alkaloid composition of 56 species of the genus Lupinus was studied by capillary gas-liquid chromatography and GLC-mass spectrometry and their relative abundances in leaves and seeds are recorded.
285 citations
TL;DR: Within the two major clades, namely Teratosphaeriaceae and Mycosphaerellaceae, most anamorph genera are polyphyletic, and new anamorph concepts need to be derived to cope with dual nomenclature within the MyCosphaerella complex.
284 citations
TL;DR: No single locus was found to be the ideal DNA barcode gene for the genus, and species identification needs to be based on a combination of gene loci and morphological characters.

TL;DR: This review begins by setting out the context and the scope of human evolution, and sets out the formal nomenclature, history of discovery, and information about the characteristic morphology, and its behavioural implications, of the species presently included in the human clade.
Abstract: This review begins by setting out the context and the scope of human evolution. Several classes of evidence, morphological, molecular, and genetic, support a particularly close relationship between modern humans and the species within the genus Pan, the chimpanzee. Thus human evolution is the study of the lineage, or clade, comprising species more closely related to modern humans than to chimpanzees. Its stem species is the so-called ‘common hominin ancestor’, and its only extant member is Homo sapiens. This clade contains all the species more closely-related to modern humans than to any other living primate. Until recently, these species were all subsumed into a family, Hominidae, but this group is now more usually recognised as a tribe, the Hominini. The rest of the review sets out the formal nomenclature, history of discovery, and information about the characteristic morphology, and its behavioural implications, of the species presently included in the human clade. The taxa are considered within their assigned genera, beginning with the most primitive and finishing with Homo. Within genera, species are presented in order of geological age. The entries conclude with a list of the more important items of fossil evidence, and a summary of relevant taxonomic issues.

TL;DR: The monophyly of Trifolium is confirmed, a new infrageneric classification of the genus is proposed, and a single origin of all North and South American species is hypothesized, while the species of sub-Saharan Africa may originate from three separate dispersal events.
