ABSTRACT Restricted range size brings about noteworthy genetic consequences that may affect the viability of a population and eventually its extinction. Particularly, question if an increase in inbreeding can avert accumulation load via purging is hotly debated conservation field. Insular populations with limited sizes represent ideal setup for relating to these factors. Leveraging set eight differently sized Galápagos mockingbirds ( Mimus ), we investigated how island shaped effective N e...
Borrelia burgdorferi is a zoonotic pathogen whose maintenance in nature depends upon an infectious cycle that alternates between tick vector and mammalian hosts. Lyme disease humans results from transmission of B. by the bite infected tick. The population dynamics throughout its natural are not well understood. We addressed this topic assessing colonization, dissemination persistence within disparate environments. To follow bacterial populations during infection, we generated seven isogenic...
Parasites are evolutionary hitchhikers whose phylogenies often track the history of their hosts. Incongruence in closely associated lineages can be explained through a variety possible events including host switching and independent speciation. However, recently diverged stochastic population processes, such as retention ancestral polymorphism or secondary contact, also explain discordant genealogies, even fully co-speciating taxa. The relatively simple biogeographic arrangement Galápagos...
The diphyllobothriid tapeworm Dibothriocephalus dendriticus, one of the causative agents fish-borne zoonosis dibothriocephalosis, is mainly distributed in Arctic/subarctic and temperate zones Northern Hemisphere (Europe, North America, Asia), but also southern cone region South America (Patagonia). genetic structure gene flow among 589 individuals D. representing 20 populations, were studied using mitochondrial cox1 as first choice marker 10 polymorphic nuclear microsatellite loci a dominant...

Organisms with wide geographical or phenotypic diversity often constitute assemblages of genetically distinct species lineages. Within parasites, an emergence host-specific lineages is assumed to create such cryptic variability; however, empirical evaluation these processes scarce. Here, we analyse populations a parasite complex life cycle, host spectrum and global distribution, the aim reveal factors underlying evolution host- geography-dependent Using 15 microsatellite loci, deep genetic...
A degree of host specificity, manifested by the processes host-parasite cospeciations and switches, is assumed to be a major determinant parasites' evolution. To understand these patterns formulate appropriate ecological hypotheses, we need better insight into coevolutionary at intraspecific level, including maintenance genetic diversity population structure parasites their hosts. Here, address questions analyzing large-scale molecular data on louse
Dicyemids and orthonectids were traditionally classified in a group called Mesozoa, but their placement single clade has been contested position(s) within Metazoa is uncertain. Here, we assembled comprehensive matrix of Lophotrochozoa (Metazoa) investigated the position Dicyemida (= Rhombozoa) Orthonectida, employing multiple phylogenomic approaches. We sequenced seven new transcriptomes one draft genome from dicyemids ( Dicyema , Dicyemennea ) two Rhopalura ). Using these published data,...
Abstract In recent decades, the world has witnessed a remarkable resurgence of bedbugs (Hemiptera: Cimicidae). Although populations common bedbug, Cimex lectularius L., expanded in temperate regions its original distribution, tropical C. hemipterus (F.), increased abundance warmer regions, where it also had been historically distributed. However, recently observed to be expanding other areas, e.g. North Australia, Middle East, United States and Russia. parts Europe, few sporadic ephemeral...
Population structure and genetic interrelationships of giant liver fluke Fascioloides magna from all enzootic North American regions were revealed in close relation with geographical distribution its obligate definitive cervid hosts for the first time. Variable fragments mitochondrial cytochrome c oxidase subunit I (cox1; 384 bp) nicotinamide dehydrogenase (nad1; 405 applied as a tool. The concatenated data set both cox1 nad1 sequences (789 contained 222 that resulted 50 haplotypes. Genetic...
The extracellular subunit of the major histocompatibility complex MHCIIβ plays an important role in recognition pathogens and initiation adaptive immune response vertebrates. It is widely accepted that pathogen-mediated selection combination with neutral micro-evolutionary forces (e.g. genetic drift) shape diversity MHCIIβ, but it has proved difficult to determine relative effects these forces. We evaluated effect drift balancing on 12 small populations Galápagos mockingbirds belonging four...
Fascioloides magna (Trematoda: Fasciolidae) is an important liver parasite of a wide range free-living and domestic ruminants; it represents remarkable species due to its large spatial distribution, invasive character, potential colonize new territories. The present study provides patterns population genetic structure admixture in F. across all enzootic regions North America natural foci Europe, infers migratory routes the on both continents. In total, 432 individuals from five American...
Laelaps agilis C.L. Koch, 1836 is one the most abundant and widespread parasitic mite species in Western Palearctic. It a permanent ectoparasite associated with Apodemus genus, which transmits Hepatozoon via host's blood. Phylogenetic relationships, genealogy host specificity of are uncertain Here, we investigated population genetic structure 132 individual mites across Europe from their Clethrionomys hosts. relationships variation populations were analyzed using cytochrome c oxidase subunit...
Abstract Dibothriocephalus latus is the most frequent causative agent of fish-borne zoonosis (diphyllobothriosis) in Europe, where it currently circulating mainly Alpine lakes region (ALR) and Russia. Three mitochondrial genes ( cox 1, cob nad 3) 6 microsatellite loci were analysed to determine how recently detected triploidy/parthenogenesis tapeworms from ALR displayed at DNA level. A geographically distant population Krasnoyarsk Reservoir Russia (RU-KR) was as a comparative population. One...
Ligula intestinalis (Linnaeus, 1758) is a tapeworm parasite with worldwide distribution that uses wide variety of fish species as its second intermediate host. In the present study, we investigated prevalence and population genetic structure plerocercoids L. in five common cyprinoid species, roach Rutilus rutilus (Linnaeus), freshwater bream Abramis brama white Blicca bjoerkna bleak Alburnus alburnus rudd Scardinius erythrophthalmus collected six water bodies Czech Republic (Milada, Most,...
Abstract Sucking lice of the parvorder Anoplura are permanent ectoparasites with specific lifestyle and highly derived features. Currently, genomic data only available for a single species, human louse Pediculus humanus. Here, we present genomes two distinct lineages, different host spectra, rodent Polyplax serrata. Genomes these ecologically lineages closely similar in gene content display conserved order genes, exception translocation. Compared P. humanus, serrata noticeably larger (139...
