The population genetics of host specificity: genetic differentiation in dove lice (Insecta: Phthiraptera)
Some species of parasites occur on a wide range of hosts while others are restricted to one or a few host species. The host specificity of a parasite species is determined, in part, by its ability toExpand

When do parasites fail to speciate in response to host speciation?
Cospeciation generally increases the similarity between host and parasite phylogenies. Incongruence between host and parasite phylogenies has previously been explained in terms of host switching,Expand

The phylogeny of the louse genus Brueelia does not reflect host phylogeny
Lice (Insecta: Phthiraptera) are often considered a model group of parasites for studies of cospeciation because of their high host specificity, and louse species in the genus Brueelia are relativelyExpand

Dramatically elevated rate of mitochondrial substitution in lice (Insecta: Phthiraptera).
Few estimates of relative substitution rates, and the underlying mutation rates, exist between mitochondrial and nuclear genes in insects. Previous estimates for insects indicate a 2-9 times fasterExpand

Phylogenetic analysis of partial sequences of elongation factor 1alpha identifies major groups of lice (Insecta: Phthiraptera).
As a first attempt to use molecular data to resolve the relationships between the four suborders of lice and within the suborder Ischnocera, we sequenced a 347-bp fragment of the elongation factorExpand

Taxonomic revision of Old World members of the feather louse genus Columbicola (Phthiraptera: Ischnocera), including descriptions of eight new species
The feather louse genus Columbicola Ewing is revised and divided into 24 species groups, with descriptions and illustrations provided for the 19 Old World species groups. Eight new species areExpand

Molecular Systematics of Goniodidae (Insecta: Phthiraptera)
The higher level phylogenetic relationships within the avian feather lice (Insecta: Phthiraptera: Ischnocera) are extremely problematic. Here we investigate the relationships of 1 familyExpand

Measuring individual differences in change with multidimensional Rasch models.
Item response models have been developed to explore change measurement, including those proposed by Fischer and his colleagues (e.g., Fischer & Pazer, 1991; Fischer & Ponocny, 1994), Andersen (1985)Expand
