“…Comparing β-diversity is an important area of basic and applied ecological research; however, few studies have addressed β-diversity in studies of communities of parasitic organisms, especially in anurans. Studies of β-diversity are carried out more commonly with parasites of mammals and fish (Krasnov et al, 2019;Qin et al, 2019;Spickett et al, 2017;Spickett et al, 2019). The present study suggests that increased research in the understanding of the patterns of spatial variation of parasite communities at the level of β-diversity will provide information that will aid in the interpretation of comparative results.…”

The helminth community of Lithobates spectabilis (n =77) was studied from Las Pilas (low altitude) and Metznoxtla (high altitude), Biosphere Reserve Barranca de Metztitlán, Hidalgo, Mexico. Species diversity was compared at the infracommunity and the component community level using Hill numbers, and the beta diversity was calculated. Five species of Digenea, 5 of Nematoda, and 2 of Acanthocephala were found in the frogs from the 2 localities. The species richness of parasites in Las Pilas (9 species) was higher than that of Metznoxtla (7 species). The helminth community in Las Pilas was dominated by nematodes and, in Metznoxtla, it was dominated by digeneans. The most prevalent species in Las Pilas was Foleyellides cf. flexicauda (65% of frogs were infected) and, in Metznoxtla, it was Megalodiscus americanus (76% were infected). Glypthelmins quieta was the species with the highest mean abundance in both localities (Las Pilas = 4.5; Metznoxtla = 11.0). The difference in species composition between the 2 localities was significant (Anosim; R = 0.54, p < 0.05). The differences in the composition of species of helminths between the 2 localities suggest that local environmental conditions are different, which may reflect differences in local host diet.

“…Our analyses demonstrated the influence of both host sex and age, as well as season of sampling on the structure and dynamics within these networks. Interestingly, and as shown in previous studies (Zelmer et al ., 2004 ; Chaisiri et al ., 2017 ; Spickett et al ., 2019 ; Junker et al ., 2022 ), the effect of a given factor on the same metric can vary between localities.…”

“…This follows the same pattern as nestedness contribution and is likely due to the same physiological and behavioural gender differences as highlighted above. Environmental gradients between the 2 localities might mediate the extent to which host heterogeneity influences parasite transmission in relation to host sex and age classes of warthogs (Spickett et al ., 2019 ; Junker et al ., 2022 ).…”

Few studies have investigated the ecological interactions between wild species of Suidae and their parasites, leaving our knowledge concerning this host–parasite system fragmented. In the present study, we applied network studies to analyse community nestedness in helminth assemblages of common warthogs, Phacochoerus africanus (Gmelin) (Suidae). Helminth data were compiled from 95 warthogs, including young and adult males and females, from 2 different conservation areas in Mpumalanga and Limpopo Provinces, South Africa, collected monthly over a period of 1 year each. The aim was to study the effect of host sex, age and season of sampling on the structure of helminth infracommunities harboured by the warthogs and to search for non-random structural patterns in the warthog–helminth interaction networks. Furthermore, we investigated the influence of a warthog's age, sex and season of sampling on beta diversity and dark diversity of their helminth infracommunities. Lastly, we asked whether the effects of host sex, age and sampling season on helminth communities differed between the 2 localities. We found that helminth communities of warthogs were nested and host–parasite interactions were influenced by all 3 factors as well as combinations thereof. However, the resulting patterns differed at the 2 localities, indicating that local environmental processes are important drivers of community structure.
