Fine-scale genetic structuring on Manacus manacus leks
In white-bearded manakins (Manacus manacus), for which larger leks are more attractive to females and so secure the maximum number of matings, there is extraordinary fine-scale genetic structure, with leks being composed of clusters of related kin.
Species assignment and hybrid identification among Scandinavian hares Lepus europaeus and L. timidus
To determine species differentiation in nuclear DNA markers, elucidate the extent of interspecific gene flow, identify true hybrids within the authors' sample and evaluate the ability of hunters to identify hybrids, it is believed that a reticulated mode of evolution among hares, with repeated gene flow over the species barrier, is responsible for low estimates.
Mapping cladograms into morphospaces

- 18 December 2002
A method for synthesizing phylogenetic results that are interpreted from cladistic analyses with phenetic results from morphological space analyses is presented here; in particular, points that represent forms typifying taxa in morphospace are assigned as terminal nodes for appropriate cladograms that are mapped into morphospaces by positioning nonterminal nodes and orienting internodes according to a geometric algorithm.
