Cím:Size matters for lice on birds: Coevolutionary allometry of host and parasite body size / Harnos Andrea, Lang Zsolt, Petrás Dóra, Bush Sarah E., Szabó Krisztián, Rózsa Lajos
Dátum:2017

Megjegyzések: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 magnitudeand variability of parasite size according to Harrison's rule (HR: positive relationship between host and parasite body sizes) andPoulin's Increasing Variance Hypothesis (PIVH: positive relationship between host body size and the variability of parasite bodysize). 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 forhost 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 familiesand guilds of avian lice follow both HR and PIVH; however, ricinids did not follow PIVH and the "body lice" guild of philopteridlice did not follow HR or PIVH. We discuss mathematical and ecological factors that may be responsible for these patterns, and wediscuss the potential pervasiveness of these relationships among all parasites on Earth.

Megjegyzések:New analytical methods are improving our ability to reconstruct robust species trees from multilocus datasets, despite difficulties in phylogenetic reconstruction associated with recent, rapid divergence, incomplete lineage sorting and/or introgression. In this study, we applied these methods to resolve the radiation of toads in the Bufo bufo (Anura, Bufonidae) species group, ranging from the Iberian Peninsula and North Africa to Siberia, based on sequences from two mitochondrial and four nuclear DNA regions (3490 base pairs). We obtained a fully-resolved topology, with the recently described Bufo eichwaldi from the Talysh Mountains in south Azerbaijan and Iran as the sister taxon to a clade including: (1) north African, Iberian, and most French populations, referred herein to Bufo spinosus based on the implied inclusion of populations from its type locality and (2) a second clade, sister to B. spinosus, including two sister subclades: one with all samples of Bufo verrucosissimus from the Caucasus and another one with samples of B. bufo from northern France to Russia, including the Apennine and Balkan peninsulas and most of Anatolia. Coalescent-based estimations of time to most recent common ancestors for each species and selected subclades allowed historical reconstruction of the diversification of the species group in the context of Mediterranean paleogeography and indicated a long evolutionary history in this region. Finally, we used our data to delimit the ranges of the four species, particularly the more widespread and historically confused B. spinosus and B. bufo, and identify potential contact zones, some of which show striking parallels with other co-distributed species.
