(Journal article; Peer reviewed, 2019)This is the first in-depth study which quantifies lice infestation levels on wild and farmed salmonids in a fjord system in Iceland (Arnarfjörður, Westfjords) and gives a baseline for the assessment of sea lice infestation ... -
Sea Lice Working Group Report
(NINA Special Report;39, Book, 2009)The collective term “sea lice” is colloquially used to refer to numerous species of copepod crustaceans of the family Caligidae that are externally parasitic on the skin of marine and anadromous fishes. The most intensively ... -
Seabird beachcast events associated with bycatch in the Norwegian purse seine fishery
(Peer reviewed; Journal article, 2022)Beachcast events, where a large number of seabird carcasses drift ashore, occur with irregular intervals. These events are due to specific situations where mass mortality of seabirds have occurred. Disentangling the cause ... -

Seasonal and elevational variability in the induction of specialized compounds from mountain birch (Betula pubescens var. pumila) by winter moth larvae (Operophtera brumata)
(Peer reviewed; Journal article, 2021)The mountain birch [Betula pubescens var. pumila (L.)] forest in the Subarctic is periodically exposed to insect outbreaks, which are expected to intensify due to climate change. To mitigate abiotic and biotic stresses, ... -
Seasonal and spatial variation of stream macroinvertebrate taxonomic and functional diversity across three boreal regions
(Peer reviewed; Journal article, 2023)1. The exploration of biodiversity has predominantly been based on taxonomicmeasures, whereas functional diversity, a key component of biodiversity, is compar-atively understudied. Therefore, studies simultaneously ... -
Seasonal habitat use of three predatory fishes in a freshwater ecosystem
(Peer reviewed; Journal article, 2022)To understand the spatiotemporal overlap in the habitat use of sympatric predators, we studied longitudinal activity and reservoir section and depth use of pike (Esox lucius), pikeperch (Sander lucioerca) and catfsh (Silurus ... -
Seasonal host and ecological drivers may promote restricted water as a viral vector
(Peer reviewed; Journal article, 2021)In climates with seasonally limited precipitation, terrestrial animals congregate at high densities at scarce water sources. We hypothesize that viruses can exploit the recurrence of these diverse animal congrega- tions ... -
Seasonal variation in growth, consumption and growth efficiency in overwintering juvenile steelhead
(Peer reviewed; Journal article, 2019)Food availability and thermal regimes can largely govern growth opportunities in fishes. In temperate regions, streams can exhibit summer temperatures that exceed the optima for coolwater-adapted species relative to the ... -
Seasonal variation in urban pollen resource use by north temperate European honeybees
(Peer reviewed; Journal article, 2023)Urban green infrastructure can provide important habitats for pollinators and support urban ecosystem services. Therefore, these areas must be managed to maximize biodiversity and density of pollinating insects. We used ... -
