On the Other “Phylogenetic Systematics”
Cladistics, 2000De Queiroz and Gauthier, in a serial paper, argue that biological taxonomy is in a sad state, because taxonomists harbor “widely held belief” systems that are archaic and insufficient for modern classification, and that the bulk of practicing taxonomists are essentialists.

Reflections on Systematics and Phylogenetic Reconstruction
Acta Biotheoretica, 2009I attempt to raise questions regarding elements of systematics--primarily in the realm of phylogenetic reconstruction--in order to provoke discussion on the current state of affairs in this discipline, and also evolutionary biology in general: e.g., conceptions of homology and homoplasy, hypothesis testing, the nature of and objections to Hennigian ...

ON THE BOUNDARIES OF PHYLOGENETIC SYSTEMATICS
Cladistics, 1986Abstract— The parsimony criterion both measures the ability of genealogical hypotheses to explain observed similarities and corresponds to Hennig's principle of grouping by synapomorphy. Sæther's proposal of grouping according to homoiology is neither Hennigian nor justified on any other grounds. Criticisms by Felsenstein that parsimony analysis may be

PHYLOGENETIC SYSTEMATICS AND THE SPECIES PROBLEM
Cladistics, 1988Abstract— A tension has arisen over the primacy of interbreeding versus monophyly in defining the species category. Manifestations of this tension include unnecessary restriction of the concept of monophyly as well as inappropriate attribution of “species” properties, to “higher taxa”, and vice versa.

PHYLOGENETIC SYSTEMATICS IN BOTANY
TAXON, 1978SummaryPhylogenetic systematics in the sense of W. Hennig has exerted a great influence on systematic zoology. Among botanists, however, it has been overlooked and the present paper is intended as a brief summary of the principles, results, and advantages of its application in botanical systematics.In phylogenetic reconstruction monophyletic groups are

Phylogenetic systematics and biomechanics in ecomorphology
Environmental Biology of Fishes, 1995Research in all fields of biology increasingly uses phylogenetic systematics to interpret biological data in an evolutionary context. It is becoming widely accepted that comparative studies of the correlation of biological features, such as ecomorphological studies, must frame their analyses within the context of a phylogenetic hierarchy rather than ...

Phylogenetic Systematics of Pontederiaceae
Systematic Botany, 1986Six different methods of cladogram construction were applied to a data set embracing 34 species and subspecies of Pontederiaceae. Nineteen Wagner trees were constructed using dif- ferent combinations of character subsets and outgroups. Although 12 trees were constructed using the largest character cliques uncovered by character compatibility analysis ...
