Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Marine Parasite Biogeography Mirrors Host Patterns Across Latitude, Area, and Diversity

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Parasites are integral components of biodiversity, yet they remain poorly represented in large‐scale biogeographic theory. In this study, we test whether marine parasites follow three macroecological patterns established for free‐living taxa, namely that parasite species richness: (1) scales positively with area (both host body size and geographic area)

Breeding systems in Echinococcus granulosus (Cestoda; Taeniidae): selfing or outcrossing?

open access: yes, 1999
We used the PCR-SSCP method followed by sequencing in order to assess the genetic variability of coding and non-coding parts of the genome of Echinococcus granulosus (Cestoda; Taeniidae) and to test whether or not the parasite populations are mainly self-

Zoonotic risks in urban areas: Prevalence of helminth parasites in urban populations of Lissachatina fulica in Sarawak, Malaysia

open access: yesVeterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background The giant African land snail (Lissachatina fulica), an invasive species with significant medical, agricultural and economic importance, is abundant in urban areas of Kota Samarahan, Sarawak. The proximity between humans and the snail may increase the risk of pathogen transmission.
