Uncovering the secrets they keep – the role of parasites in food web ecology

Autor: Moore, Shannon Elizabeth

Interactions involving parasites often account for large proportions of links within aquatic food webs, yet few studies integrate parasites into their food web analyses. This analysis compares three sets of highly resolved food webs that differ in ta

Molecular study of digenean diversity in aquatic organisms in northern Norway, with a focus on the seasonality of Crepidostomum [Braun, 1900]

Autor: Slåteng, Sigurd

This study aimed to elucidate cryptic trematode diversity across multiple life stages in aquatic organisms. I collected samples from first intermediate hosts (bivalves), second intermediate hosts (amphipods and insect nymphs), and definitive hosts (f

Comparison of the parasite communities of brown trout (Salmo trutta) from two coastal lakes in central Norway

Autor: Lægran, Astrid

There are several studies concerning parasite communities in brown trout (Salmo trutta) and other salmonids in Norwegian lakes. These are mainly conducted in deeper oligotrophic inland lakes with a few coastal exceptions. Coastal lakes with eutrophic

Rodent population cycle as a determinant of gastrointestinal nematode abundance in a low-arctic population of the red fox

Publikováno v: International Journal for Parasitology: Parasites and Wildlife, Vol 9, Iss, Pp 36-41 (2019)
International Journal for Parasitology: Parasites and Wildlife

We analyzed an 11-year time series (2005–2015) of parasite abundance for three intestinal nematode species in the red fox (Vulpes vulpes) as a function of the multi-annual rodent population cycle in low-arctic Norway, while correcting for other pot

Infeksjon av fiskandmark (Dibothriocephalus ditremus) og måsemark (D. dendriticus) hos ørret (Salmo trutta) i Takvatnet gjennom de siste 20 årene

Autor: Johannessen, Julie Johanne

Næringsdyroverførte parasitter er viktige i undersøkelsen av vertens diett og habitat over tid. Dibothriocephalus ditremus (fiskandmark) og D. dendriticus (måsemark) er en av de mest alvorlige parasitter hos fisk i arktiske innsjøer da de kan p�

Gastrointestinal nematodes in Icelandic reindeer (Rangifer tarandus tarandus)

Autor: Dembereldagva, Selengemurun

Reindeer (Rangifer tarandus) are host to gastrointestinal-tract nematodes (GINs) throughout the world. Some populations of reindeer exist in almost complete isolation from others, and this can have a key influence on the species and infection rates o

Long-term dynamics of metazoan parasites in an age- and size-structured host population

Autor: Henriksen, Eirik Haugstvedt

Parasites negatively affect hosts and may constitute serious management problems. At the same time, parasites are integral components of ecosystems and represent a substantial part of the biodiversity on earth. Understanding the ecological factors th

Seasonal dietary shifts enhance parasite transmission to lake salmonids during ice cover

Ecology and Evolution

Changes in abiotic and biotic factors between seasons in subarctic lake systems are often profound, potentially affecting the community structure and population dynamics of parasites over the annual cycle. However, few winter studies exist and intera

Pathogens can impact host survival, fecundity, and population dynamics even when no obvious disease is observed. Few baseline data on pathogen prevalence and diversity of caribou are available, which hampers our ability to track changes over time and
