Journal ArticleDOI
The polyphyly of Plasmodium: comprehensive phylogenetic analyses of the malaria parasites (order Haemosporida) reveal widespread taxonomic conflict.
Spencer C. Galen,Janus Borner,Ellen S. Martinsen,Juliane Schaer,Christopher C. Austin,Christopher J. West,Susan L. Perkins +6 more
TL;DR: The most comprehensive phylogenetic analysis of the malaria parasites conducted to date is presented, finding that Plasmodium, the malaria parasite genus that includes the species of human medical concern, is polyphyletic with the life-history traits characteristic of this genus having evolved in a dynamic manner across the phylogeny.
Journal ArticleDOI
Contribution of a mutational hot spot to hemoglobin adaptation in high-altitude Andean house wrens.
Spencer C. Galen,Chandrasekhar Natarajan,Hideaki Moriyama,Roy E. Weber,Angela Fago,Phred M. Benham,Andrea N. Chavez,Zachary A. Cheviron,Jay F. Storz,Christopher C. Witt +9 more
TL;DR: The experimental results highlight the influence of mutation rate on the genetic basis of phenotypic evolution by demonstrating that a large-effect allele at a highly mutable CpG site has promoted physiological differentiation in blood O2 transport capacity between house wren populations that are native to different elevations.
Journal ArticleDOI
Diverse avian malaria and other haemosporidian parasites in Andean house wrens: evidence for regional co-diversification by host-switching
TL;DR: A model of diff use co-diversifi cation is suggested in which host and parasite clades have diversifi ed over the same time period and in the same geographic area, but with parasites having limited or ephemeral host specifi city.
Journal ArticleDOI
Deeply conserved susceptibility in a multi-host, multi-parasite system.
Lisa N. Barrow,Sabrina M. McNew,Sabrina M. McNew,Nora Mitchell,Spencer C. Galen,Holly L. Lutz,Heather R. Skeen,Thomas Valqui,Jason D. Weckstein,Christopher C. Witt +9 more
TL;DR: This study suggests that susceptibility is governed, in part, by conserved, latent aspects of anti-parasite defence, demonstrating the importance of deep phylogeny for understanding present-day ecological interactions.
Journal ArticleDOI
An inverse latitudinal gradient in infection probability and phylogenetic diversity for Leucocytozoon blood parasites in New World birds.

TL;DR: The results show that integrating host traits, host ancestry, bioclimatic data, and microhabitat characteristics that are important for vector reproduction are imperative to understand and predict infection prevalence and diversity of vector-transmitted parasites.
