An overview of helminths of the European fire-bellied toad Bombina bombina (Amphi-bia, Anura) in the Volga River Basin

open access: yesBiosystems Diversity, 2021
The helminthofauna of Bombina bombina (Linnaeus, 1761) has been studied to an unequal degree in different parts of the habitat. Thus, it has been studied in more detail in the west of its range (in the countries of central and eastern Europe) and in less

Metabarcoding of Sediment eDNA Uncovers Ecological Gradients and Biodiversity in Philippine Mangroves

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Community diversity metrics revealed a clear ecological gradient, with the highest diversity observed in recolonized mature stands, intermediate in the natural stands, and lowest in the restored stands. Taxonomic profiles varied with mangrove stand, age, and zonation.

Twenty Years after De Ley and Blaxter—How Far Did We Progress in Understanding the Phylogeny of the Phylum Nematoda?

open access: yes, 2021
Molecular phylogenetics brought radical changes to our understanding of nematode evolution, resulting in substantial modifications to nematode classification implemented by De Ley and Blaxter and widely accepted now.

How Host Phylogeny and Diet Shape the Specificity and Specificity Diversity of Animal Gut Microbiomes

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
By identifying unique/enriched microbial species across taxa and diet types in 318 animal species with our SSD (specificity and specificity diversity) framework, we demonstrated that host phylogeny and diet are joint drivers of microbial specificity compositional heterogeneity, potentially linking the macroecological pattern of phylosymbiosis with the ...

Evolutionary rates of mitochondrial sequences and gene orders in Spirurina (Nematoda) are episodic but synchronised

open access: yesWater Biology and Security, 2022
In contrast to highly conserved mitogenomic architecture in most metazoan lineages, which indicates that rearrangement events are generally strongly selected against, a limited number of often unrelated lineages exhibit highly elevated architectural ...
