“…Specificity as exhibited by dilepidid cestodes of the Alcidae (those in puffins, auklets, guillemots and murres) is indicated by complete development (egg production) being limited to a narrow range of related hosts (generally congeners) (Hoberg 1 984a). This observation is compatible with the assertion of Rausch (1983) that specificity can be represented by a "positive-negative dichotomy." Data concerning parasites of alcids do not support the contention by Dogie1 (1964), Holmes et al (1977), and Holmes (1979) that specificity is a continuum over a range of preferred to nonpreferred hosts.…”

HOBERG, E. P. 1986. Evolution and historical biogeography of a parasite-host assemblage: Alcataenia spp. (Cyclophyllidea: Dilepididae) in Alcidae (Charadriiformes) . Can. J. Zool . 64: 2576-2589.The methodology of phylogenetic systematics was used to develop hypotheses for the evolution of eight species of Alcataenia, a group of host-specific cestodes of the Alcidae and, to a lesser extent, the Laridae (Charadriiformes). Concurrently, aspects of the early biogeography of alcids were reevaluated making it possible to study the historical and distributional relationships of parasites and hosts. The most parsimonious hypothesis for the phylogeny of Ale-crtcrenicr suggested that sequential colonization or host switching with limited coevolution (coaccommodation) by parasites best explained the distributional patterns exhibited by Alcataenia spp. Morphological evolution of specific species of Alcataenia accompanied host switching, but was limited subsequent to the initial event of colonization. Thus evolution of these parasites following colonization lagged behind continuing diversification of the host group. Although alcids are an ancient group, as indicated by palaeontological and phylogenetic data, their cestode fauna is apparently not. It is postulated that Alcataenia spp. were acquired by their characteristic hosts in the late Pliocene and early Pleistocene, following diversification of the Alcidae at the generic level during the Miocene. Host distributions of respective Alcataenia spp. are more narrow than expected, considering the relatively young age of this assemblage. The current paradigm linking pronounced host specificity with coevolution of hosts and parasites in assemblages of great evolutionary age is not supported.HOBERG, E. P. 1986.

L'hypothese la plus simple sur la phylogenie d'Alcataenia suggere que la colonisation ~Cquentielle, ou changement d'h6te par les parasites et coCvolution limitCe (coaccomodation), est le phCnomkne qui peut 1e mieux expliquer la repartition actuelle des especes d'Alcatuenia. Certaines espkces particulieres d'Alcataenia ont subi une Cvolution morphologique en changeant d'hate, mais cette Cvolution a 6tC ralentie apres le debut de la colonisation.

“…Eimeria and nematodes are the most common species, probably because of their direct life cycles, while lower levels of trematode and cestode infections may be due to an indirect life history (Rausch 1983). From the results of this study, we found that the prevalence of parasites was higher in the Poyang population, suggesting that it is more prone to infection.…”

Background: Parasites have adverse effects on the life and survival of many migratory waterbirds, especially birds on the endangered species list. Hooded Cranes are large migratory colonial waterbirds wintering in wetlands, which are prone to parasite infection, thus monitoring the diversity of parasites is important for sound wetland management and protection of this species. Methods: From November 2012 to April 2013, we collected 821 fresh faecal samples from the three lakes (Poyang, Caizi and Shengjin Lake) in the lower and middle Yangtze River floodplain, and detected with saturated brine floating and centrifugal sedimentation methods. Parasite eggs were quantified with a modified McMaster's counting method.

“…However, even with seemingly barely pathogenic species, as are most avian helminths according to Rausch (1983), immunity to helminth parasites is evidently crucial to the host (e.g. Ito, 1985).…”

Parasites and the avian spleen: helminths

A comparative analysis of the relationship between the spleen–a major organ of immunity and helminths was undertaken with bird species, using the phylogenetic regression technique. Species in which many individuals are infected with nematodes relative to the number of individuals examined for the presence of helminths (termed ‘relative nematode presence’) have significantly larger spleens, for a given body weight, in females (though not in males). There was little indication that this relationship depends on incidental ecological indices, the weights of other organs, or the ‘relative presences' of trematodes, cestodes or haematozoa. Combined with previous, experimental, work it suggests that the avian spleen is important in resisting nematodes. Body weight is correlated with the relative presence of helminths; but even after removing body size effects, bird species which tend to be infected with trematodes are also more likely to be infected with cestodes. This paper indicates that the spleens of wild bird species are associated with macroparasites in the natural environment.
