  • 1 February 2004
Historically, comparisons of host and parasite phylogenies have concentrated on cospeciation. However, many of these comparisons have demonstrated that the phylogenies of hosts and parasites are… Expand

Parasite Prevalence Corresponds to Host Life History in a Diverse Assemblage of Afrotropical Birds and Haemosporidian Parasites
Avian host life history traits have been hypothesized to predict rates of infection by haemosporidian parasites. Using molecular techniques, we tested this hypothesis for parasites from three… Expand

Evolutionary history of Ramphastos toucans: molecular phylogenetics, temporal diversification, and biogeography.
The toucan genus Ramphastos (Piciformes: Ramphastidae) has been a model in the formulation of Neotropical paleobiogeographic hypotheses. Weckstein (2005) reported on the phylogenetic history of this… Expand

Comparative Phylogenetic Histories of Two Louse Genera Found on Catharus Thrushes and Other Birds
Abstract The louse genera Brueelia (Ischnocera) and Myrsidea (Amblycera) are broadly codistributed on songbirds (Passeriformes), but differ in a variety of life history characteristics. We used… Expand

The perils of using host relationships in parasite taxonomy: phylogeny of the Degeeriella complex.
The taxonomy of lice (Insecta: Phthiraptera) is often heavily influenced by host taxonomy. The use of host information to define genera of avian lice in the widespread Degeeriella complex has been… Expand

The Central American land bridge as an engine of diversification in New World doves
Aim The closure of the Central American land-bridge connection between North and South America 3.5 million years ago was a major biogeographic event that allowed considerable interchange of the… Expand

Temporal and spatial diversification of Pteroglossus araçaris (AVES: Ramphastidae) in the neotropics: constant rate of diversification does not support an increase in radiation during the Pleistocene.
We use the small-bodied toucan genus Pteroglossus to test hypotheses about diversification in the lowland Neotropics. We sequenced three mitochondrial genes and one nuclear intron from all… Expand

Climate variation influences host specificity in avian malaria parasites.
Parasites with low host specificity (e.g. infecting a large diversity of host species) are of special interest in disease ecology, as they are likely more capable of circumventing ecological or… Expand

A new real-time PCR protocol for detection of avian haemosporidians
BackgroundBirds possess the most diverse assemblage of haemosporidian parasites; including three genera, Plasmodium, Haemoproteus, and Leucocytozoon. Currently there are over 200 morphologically… Expand

There and back again: Switching between host orders by avian body lice (Ischnocera: Goniodidae)
Studies of major switches by parasites between highly divergent host lineages are important for understanding new opportunities for parasite diversification. One such major host switch is inferred… Expand
