	abstract = {<p>Lice (Insecta: Phthiraptera) are ectoparasites that reduce host life expectancy and sexual attractiveness. Their taxonomic richness varies considerably among their hosts. Previous studies have already explored some important factors shaping louse diversity. An unexplored potential correlate of louse taxonomic richness is host behavioural flexibility. In this comparative study, we examine the relationship between louse generic richness, innovative capabilities (as a proxy for behavioural flexibility), and brain size while controlling for host species diversity, phylogeny, body size and research effort. Using data for 108 avian families, we found a highly ignificant positive relationship between host innovative capabilities and the taxonomic richness of amblyceran lice, but a lack of a similar relationship in ischnoceran lice. Host brain size had only a marginal impact on amblyceran diversity and no correlation with ischnoceran diversity. This suggests that the effect in Amblycera is not mediated by metabolic limitations due to the energetic costs of brain size and maintenance, rather directly caused by the ecological differences between hosts with differing cognitive capabilities. We propose four alternative and mutually non-exclusive hypotheses that may explain this phenomenon.</p>

	abstract = {<p>Two competing views have been expressed to explain ectoparasite speciation patterns, one emphasizing co-speciation and the other emphasing host switching. Though recent authors prefered a combination of these views, the available phylogenetic trees cannot be interpreted without revisiting island biogeography theory. Parasite extinction due to a temporal decline in host population size seems to be a prerequisite of subsequent speciation by host-switch. The need for a re-evaluation of \&quot;stragglers\&quot; (ectoparasites found on non-specific hosts) is emphasized.</p>
