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

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.
