“…There are hemimetabolous insects (Plecoptera, Ephemeroptera, Odonata), which pass metacercariae into the imago stage (Mariluan et al, 2012) and are potentially better vectors for trematode transfer to onshorefeeding hosts, but their imago stages are rare in Pelophylax spp. diets (Tyler, 1958;Balint et al, 2008;Paunovic et al, 2010). Interestingly, infections of several plagiorchiids (Gorgodera varsoviensis, S. similis), having a second intermediate stage mainly in hemimetabolous Odonata (Sudarikov et al, 2002), had no correlation with the waterbody area in our study.…”

Helminth communities in amphibians from Latvia, with an emphasis on their connection to host ecology

et al. 2021

Helminth infracommunities were studied at 174 sites of Latvia in seven hosts from six amphibian taxa of different taxonomical, ontogenic and ecological groups. They were described using a standard set of parasitological parameters, compared by ecological indices and linear discriminant analysis. Their species associations were identified by Kendall's rank correlation, but relationships with host size and waterbody area were analysed by zero-inflated Poisson and zero-inflated negative binomial regressions. The richest communities (25 species) were found in post-metamorphic semi-aquatic Pelophylax spp. frogs, which were dominated by trematode species of both adult and larval stages. Both larval and terrestrial hosts yielded depauperate trematode communities with accession of aquatic and soil-transmitted nematode species, respectively. Nematode loads peaked in terrestrial Bufo bufo. Helminth infracommunities suggested some differences in host microhabitat or food object selection not detected by their ecology studies. Associations were present in 96% of helminth species (on average, 7.3 associations per species) and dominated positive ones. Species richness and abundances, in most cases, were positively correlated with host size, which could be explained by increasing parasite intake rates over host ontogeny (trematode adult stages) or parasite accumulation (larval Alaria alata). Two larval diplostomid species (Strigea strigis, Tylodelphys excavata) had a negative relationship with host size, which could be caused by parasite-induced host mortality. The adult trematode abundances were higher in larger waterbodies, most likely due to their ecosystem richness, while higher larval abundances in smaller waterbodies could be caused by elevated infection rates under high host densities.

The feeding of four amphibian species (Triturus cristatus, Lissotriton vulgaris, Bombina variegata, Pelophylax ridibundus) was studied in 2011, in south–western Romania. The diet of the newts was uniform and mostly composed of aquatic preys The diet of the anurans was more diversified, comprising more prey taxa, mostly terrestrial. The trophic niches of the two newt species overlapped highly but differed from those of the anurans. The trophic niches of the anurans differed from one another. The differences among the four species’ diets were determined by the use of different trophic resources, originating from different environments, and by their different sizes. The newts’ diet was less diversified because the aquatic habitat was small and poor in trophic availability. The anurans used the aquatic habitat as a base from where they captured terrestrial preys in the surrounding terrestrial environment.

“…Species consuming hard and large prey have taller and wider heads that can accommodate larger jaw muscles and increase the bite force [28,53,55]. However, studies of diet in European green frogs, including the pool frog, are limited as regards diet composition [56][57][58], with only one study analyzing prey size and its correlation with body size [59]. Studies in juvenile and adult specimens of water frogs from the Pelophylax esculentus complex showed that they have different diets [58,60], while the degree of trophic niche overlap between them indicated the existence of ontogenetic trophic niche partitioning [60].…”

Post-metamorphic ontogenetic changes in head size and shape of the pool frog (Pelophylax lessonae, Ranidae).Abstract: Post-metamorphic ontogenetic variations of head size and shape were investigated in the pool frog (Pelophylax lessonae, Ranidae). We showed that allometry is an important aspect of the post-metamorphic ontogeny of the pool frog as most of the differences between the head shape of subadults and adults were size-related adjustments. The largest changes affected by size variations included the posterior part of the head and the snout and eye region. In comparison to subadults, adults have wider heads, shorter snouts and relatively smaller eyes. Analyses of the relationships between head size and shape and the maximum size of the prey indicated the absence of correlations in adults. A positive correlation was found in subadults, but only between head width and the maximum size of the prey. Further studies will allow us to draw more generalized conclusions about the ecological relevance of the variations in head size and shape during post-metamorphic development of the pool frog.
