Molecular analyses reveal high cryptic diversity of trematodes in a sub-Arctic lake
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-14)
To identify trematode diversity and life-cycles in the sub-Arctic Lake Takvatn, Norway, we characterised
120 trematode isolates from mollusc first intermediate hosts, metacercariae from second intermediate
host fishes and invertebrates, and adults from fish and invertebrate definitive hosts, using molecular
techniques. Phylogenies based on nuclear and/or mtDNA revealed high species richness (24 ...
Ontogenetic dynamics of infection with Diphyllobothrium spp. cestodes in sympatric Arctic charr Salvelinus alpinus (L.) and brown trout Salmo trutta L.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-23)
The trophic niches of Arctic charr and brown trout differ when the species occur in
sympatry
. Their
trophically transmitted parasit
es are expected to reflect these
differences.
Here
, we investigate how the infections
of
Diphyllobothrium dendriticum
and
Diphyllobothrium ditremum
differ between
charr and trout. These tapeworms use
copepods ...
High parasite diversity in the amphipod Gammarus lacustris in a subarctic lake
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-05)
Amphipods are often key species in aquatic food webs due to their functional roles in the ecosystem and as intermediate hosts for trophically transmitted parasites. Amphipods can also host many parasite species, yet few studies address the entire parasite community of a gammarid population, precluding a more dynamic understanding of the food web. We set out to identify and quantify the parasite ...
