The marine environment includes diverse microeukaryotic organisms that play important
functional roles in the ecosystem. With molecular approaches, eukaryotic taxonomy has …

This study provides a morphological, ultrastructural, and phylogenetic characterization of a
novel micro‐eukaryotic parasite (2.3–2.6 µm) infecting amphipod genera Echinogammarus …

Biological invasions may act as conduits for pathogen introduction. To determine which
invasive non-native species pose the biggest threat, we must first determine the symbionts …

Dispersal of alien species is a global problem threatening native biodiversity. Co-
introduction of non-native parasites and pathogens adds to the severity of this threat, but this …

The velvet swimming crab Necora puber has been fished in Ireland since the early 1980s
and contributes significant income to smaller fishing vessels. From 2016 onwards, reduced …

Invasive non-native amphipods (Crustacea) are becoming a model system in which to
explore the impact and diversity of invasive parasites—parasites that are carried along an …

Wild Acetes sibogae australis from northern Moreton Bay, Australia displaying opacity of the
hepatopancreas were sampled and examined histologically, revealing infection by …

Amphipods are a group of globally abundant Crustacea present throughout terrestrial,
marine and freshwater ecosystems. These organisms host a highly diverse systematic …

This paper reviews current knowledge of the structure, genesis, cytochemistry and putative
functions of the haplosporosomes of haplosporidians (Urosporidium, Haplosporidium …

Temperature and pH can expedite the ability of pathogens to cause diseases in cold-water
corals (CWCs). The present study employed a combination of histology and polymerase …
