Monographic Studies In The Genus Polyporus (Basidiomycotina), Dirk Krueger
Doctoral Dissertations
The aim of this dissertation research was an examination of the homobasidiomycete genus Polyporus as currently circumscribed. Emphasis was on addressing the genus by a variety of tools appropriate to modern monographic studies, without producing another worldwide monograph. In addition to morphological examination, which traditionally was the basis of all fungal systematics, mating experiments with monokaryotic cultures, and contemporary phylogenetic tools were used.

Master's Theses
Leptodactylus fuscus is a broadly distributed frog species in the Neotropical region. Previous allozymic evidence supported the hypothesis of L. fuscus as a composite of several species. However, morphological and advertisement call data supported the hypothesis of a single-species taxon. These competing hypotheses were evaluated using cladistic analyses of mitochondrial DNA sequences. Fragments of 12S rRNA, 16S rRNA, and ND1 protein-coding genes from 17 populations were sequenced. Phylogenetic analyses were performed using: maximum parsimony, maximum likelihood, and Bayesian analysis. Data sets were analyzed separately and combined. Analyses of the combined data set show four exclusive clades of L. fuscus: …
