“…A similar specificity at the level of host genus was observed among hymenolepidids from various Soricidae (Binkienė et al 2011). Faunal assembly and specificity are a reflection of historical and microevolutionary processes that have structured the biosphere and thus lead to predictions about the distribution of helminth diversity in space and time (e.g., Hoberg et al 2012). Interacting abiotic and biotic mechanisms, and patterns of isolation over time, support the concept that endemic hosts may be predicted to have unique helminth faunas.…”

“…Faunal assembly involving temporal and geographic mosaics related to recurrent events of geographic expansion and contact among potential host groups and host switching appear to be important drivers in establishing regional assemblages of cestodes among rodents (e.g., Haukisalmi et al 2010b;Hoberg et al 2012;Makarikov et al 2012). For example, among hymenolepidids, the genus Arostrilepis appears to be the sister of tapeworms among Soricomorpha with origins then attributable to host colonization of Arvicolinae (e.g., Haukisalmi et al 2010a); subsequent diversification reflects episodes of host colonization among geomyid and neotomine rodents (e.g., Makarikov et al 2012;Hoberg et al 2012).…”

Considering H. folkertsi, morphological similarity among Nearctic species is observed for H. tualatinensis in a geomyid from central Oregon, H. pitymi in an arvicoline from Tennessee, and H. robertrauschi in species of Onychomys a related neotomine, and putative sister of Peromyscus, across west-central North America from southern Canada to northern Mexico.…”

“…The taxonomy and biogeography of these rodents are particularly intricate reflecting both the temporal duration of this group with origins in the late Miocene and early Pliocene in the Nearctic and the range of habitats that are occupied by various species (e.g., Kurtén and Anderson 1980;Avise et al 1983;Dragoo et al 2006). The extensive geographic range of this assemblage suggests the potential for substantial insights about the history and patterns of North American biogeography and ecology, which can be revealed by exploring diversity and faunal assembly of complex hostparasite systems (e.g., Whitaker Jr 1968;Whitaker and Hamilton 1998;Hoberg et al 2012;Makarikov et al 2013a).…”

A previously unrecognized species of hymenolepidid cestode attributable to Hymenolepis is described based on specimens in Peromyscus polionotus, oldfield mouse, from Georgia near the southeastern coast of continental North America. Specimens of Hymenolepis folkertsi n. sp. differ from those attributed to most other species in the genus by having testes arranged in a triangle and a scolex with a prominent rostrum-like protrusion. The newly recognized species is further distinguished by the relative position and length of the cirrus sac, shape of seminal receptacle, and relative size of external seminal vesicle and seminal receptacle. Hymenolepidid cestodes have sporadically been reported among the highly diverse assemblage of Peromyscus which includes 56 distinct species in the Nearctic. Although the host genus has a great temporal duration and is endemic to the Nearctic, current evidence suggests that tapeworm faunal diversity reflects relatively recent assembly through bouts of host switching among other cricetid, murid, and geomyid rodents in sympatry.

“…This coevolutionary period would have resulted in the acquired immunity to the current assemblage of Nearctic parasites infecting the mammals dispersing southwards after the continental connection. This phenomenon of coevolution has been amply documented for parasites and mammals in the Northern Hemisphere (Hoberg et al 2012). The proper information necessary to build or to develop the adaptive immunity was not widespread in the South American Neotropical mammals, which in addition featured a relatively low fecundity (many, if not most, Hystricognath rodents, marsupials and xenarthrans have a relatively low intrinsic rate of natural increase relative to the invading sigmodontine rodents).…”

The Great American Biotic Interchange (GABI) is a large-scale zoogeographic event that illustrates the exchange and diversification of mammals between North and South America. This phenomenon was accelerated by the connection of both landmasses during the Pliocene. Support for this phenomenon includes the extant distribution of xenarthrans, didelphiomorph marsupials, hystricognath and cricetine rodents, sciurids and carnivores, as well as the distribution of fossils in the stratigraphic record and the coalescence of genotypes. Contrasting with the relatively well-documented role and history of mammals in GABI, the role of their parasites has been largely neglected. As a consequence, the reconstructions of the causes of diversification, extinction and dispersion of groups of mammals during the Pliocene (and Miocene) invoke changes in climate patterns and the role of competitors or predators, yet in most cases the lines of evidence are not direct. We posit that infections with parasites offer a direct form of evidence of the role of interactions among species, by considering that the successful establishment of species of parasites in new groups of vertebrates will result in a net effect on their adaptive immune system. Thus, the current distribution of nematode parasites of the families Aspidoderidae, Nippostrongylidae, Onchocercidae, Oxyuridae, Rictaluriidae and Viannaidae offers evidence that the historical associations of these nematodes and their hosts diverge from the expected cospeciation and codivergence. Thus, clades of parasites infect disparate clades of mammals and, by deviating from the expected cospeciation, represent a paradox. This paradox deters investigators from studying historical associations among symbionts, since researchers lose the compelling simplicity of testing coevolutionary associations through the congruence of their resulting phylogenies. However, the reconstruction of historical associations must acknowledge the differential survival of parasites in novel hosts. This consideration is part of the Stockholm Paradigm, which includes the hypotheses known as Ecological Fitting, Oscillations, Taxon Pulses and Mosaics of Geographic Coevolution. We introduce nine host-parasite systems that provide insights on the role of parasites in GABI. We posit that the conservatism of parasite resource use, heritability of the adaptive immune system, and the genetic structure of parasites make it possible to elucidate the role of these parasites in GABI.

A fine‐scale phylogenetic assessment of digenean trematodes in central Alberta reveals we have yet to uncover their total diversity

Despite over 100 years of digenean trematode parasite species descriptions, from a wide diversity of vertebrate and invertebrate host species, our ability to recognize the diversity of trematode species within a single lake remains an incredible challenge. The most challenging aspect is the identification of species from larval stages derived from intermediate hosts, due to the disjointed data of adult worm morphological descriptions, from which species are named, and links to corresponding molecular identifiers in depauperate databases. Cryptic species also play a significant role in the challenge of linking trematode larvae to adults, species identifications, and estimating diversity. Herein, we utilize a large, longitudinal dataset of snail first‐intermediate host infection data from lakes in Alberta, Canada, to infer trematode larval diversity using molecular phylogenetics and snail host associations. From our assessments, we uncover a diversity of 79 larval trematode species among just five snail host species. Only 14 species were identified to a previously described species, while the other 65 species are either cryptic or otherwise unrepresented by mitochondrial genes in GenBank. This study currently represents the largest and most diverse singular molecular survey of trematode larval fauna composed of over one thousand mitochondrial sequences. Surprisingly, rarefaction analyses indicate we have yet to capture the complete diversity of trematodes from our sampling area.
