“…To determine whether area of endemism had a significant phylogenetic signal in the evolutionary history of Parahaemoproteus and Plasmodium within Amazonia, we conducted a randomization test (Maddison and Slatkin 1991) for each haemosporidian clade in R ver. 3.3.2 ( www.r-project.org ), as described by Bush et al (2016). A significant result would indicate that the area of endemism distribution within the tree topology is more conserved than expected by chance, showing a significant biogeographic constraint within the phylogeny.…”

Understanding how pathogens and parasites diversify through time and space is fundamental to predicting emerging infectious diseases. Here, we use biogeographic, coevolutionary and phylogenetic analyses to describe the origin, diversity, and distribution of avian malaria parasites in the most diverse avifauna on Earth. We first performed phylogenetic analyses using the mitochondrial cytochrome b (cyt b) gene to determine relationships among parasite lineages. Then, we estimated divergence times and reconstructed ancestral areas to uncover how landscape evolution has shaped the diversification of Parahaemoproteus and Plasmodium in Amazonia. Finally, we assessed the coevolutionary patterns of diversification in this host–parasite system to determine how coevolution may have influenced the contemporary diversity of avian malaria parasites and their distribution among Amazonian birds. Biogeographic analysis of 324 haemosporidian parasite lineages recovered from 4178 individual birds provided strong evidence that these parasites readily disperse across major Amazonian rivers and this has occurred with increasing frequency over the last five million years. We also recovered many duplication events within areas of endemism in Amazonia. Cophylogenetic analyses of these blood parasites and their avian hosts support a diversification history dominated by host switching. The ability of avian malaria parasites to disperse geographically and shift among avian hosts has played a major role in their radiation and has shaped the current distribution and diversity of these parasites across Amazonia.

“…This minimum number of transitions was compared with a null distribution that was obtained by randomly permutating the host phenotypes on the consensus tree and estimating the minimum number of transitions for each permutation. The permutation analysis was performed using the R function phylo.signal.disc that was developed for a previous analysis (Bush et al., 2016). Both analyses, the comparison with the star tree and the permutation analysis, were performed for the alignment of each locus and the alignment of the concatenated sequences.…”

The endosymbiotic bacterium Wolbachia infects a wide range of arthropods and their relatives. It is an intracellular parasite transmitted through the egg from mother to offspring. Wolbachia can spread and persist through various means of host reproductive manipulation. How these different mechanisms of host manipulation evolved in Wolbachia is unclear. Which host reproductive phenotype is most likely to be ancestral and whether evolutionary transitions between some host phenotypes are more common than others remain unanswered questions. Recent studies have revealed multiple cases where the same Wolbachia strain can induce different reproductive phenotypes in different hosts, raising the question to what degree the induced host phenotype should be regarded as a trait of Wolbachia. In this study, we constructed a phylogenetic tree of Wolbachia and analyzed the patterns of host phenotypes along that tree. We were able to detect a phylogenetic signal of host phenotypes on the Wolbachia tree, indicating that the induced host phenotype can be regarded as a Wolbachia trait. However, we found no clear support for the previously stated hypothesis that cytoplasmic incompatibility is ancestral to Wolbachia in arthropods. Our analysis provides evidence for heterogeneous transition rates between host phenotypes.

“…, Bush et al. ), they do share distinct morphological and behavioral characteristics that appear to be adaptations for particular microhabitats on the body of their hosts. Head lice have plump bodies and large triangular heads, with which they grasp feathers to avoid being detached when the host scratches.…”

Size matters for lice on birds: Coevolutionary allometry of host and parasite body size

Body size is one of the most fundamental characteristics of all organisms. It influences physiology, morphology, behavior, and even interspecific interactions such as those between parasites and their hosts. Host body size influences the magnitude and variability of parasite size according to Harrison's rule (HR: positive relationship between host and parasite body sizes) and Poulin's Increasing Variance Hypothesis (PIVH: positive relationship between host body size and the variability of parasite body size). We analyzed parasite-host body size allometry for 581 species of avian lice (∼15% of known diversity) and their hosts. We applied phylogenetic generalized least squares (PGLS) methods to account for phylogenetic nonindependence controlling for host and parasite phylogenies separately and variance heterogeneity. We tested HR and PIVH for the major families of avian lice (Ricinidae, Menoponidae, Philopteridae), and for distinct ecological guilds within Philopteridae. Our data indicate that most families and guilds of avian lice follow both HR and PIVH; however, ricinids did not follow PIVH and the "body lice" guild of philopterid lice did not follow HR or PIVH. We discuss mathematical and ecological factors that may be responsible for these patterns, and we discuss the potential pervasiveness of these relationships among all parasites on Earth.
