Adaptive host responses to infection can resemble parasitic manipulation
(Journal article; Peer reviewed, 2023)Using a dynamic optimisation model for juvenile fish in stochastic food environments, we investigate optimal hormonal regulation, energy allocation and foraging behaviour of a growing host infected by a parasite that only ... -
“A cleaner break”: Genetic divergence between geographic groups and sympatric phenotypes revealed in ballan wrasse (Labrus bergylta)
(Journal article; Peer reviewed, 2020)Capture and long‐distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in ... -
Complex sublinear burrows in the deep sea may be constructed by amphipods
(Journal article; Peer reviewed, 2023)Trails, burrows, and other “life traces” in sediment provide important evidence for understanding ecology—both of the maker and of other users—and behavioral information often lacking in inaccessible ecosystems, such as ... -
Considering sampling bias in close-kin mark–recapture abundance estimates of Atlantic salmon
(Journal article; Peer reviewed, 2021)Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close-kin mark–recapture (CKMR) is based on the principles of conventional mark–recapture, but instead of being ... -
Control region sequences indicate that multiple externae represent multiple infections by Sacculina carcini (Cirripedia: Rhizocephala)
(Peer reviewed; Journal article, 2014-07-29)The rhizocephalan barnacle, Sacculina carcini, is a common parasite of the European shore crab, Carcinus maenas, in which it causes significant detrimental physical and behavioral modifications. In the vast majority of ... -
The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project
(Peer reviewed; Journal article, 2017-01)The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples ... -
Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
(Journal article; Peer reviewed, 2022)The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy ... -
Diversification in evolutionary arenas—Assessment and synthesis
(Journal article; Peer reviewed, 2020)Understanding how and why rates of evolutionary diversification vary is a key issue in evolutionary biology, ecology, and biogeography. Evolutionary rates are the net result of interacting processes summarized under concepts ... -
Diversity of European habitat types is correlated with geography more than climate and human pressure
(Journal article; Peer reviewed, 2021)Habitat richness, that is, the diversity of ecosystem types, is a complex, spatially explicit aspect of biodiversity, which is affected by bioclimatic, geographic, and anthropogenic variables. The distribution of habitat ... -
Duration of the parasitic phase determines subsequent performance in juvenile freshwater pearl mussels (Margaritifera margaritifera)
(Peer reviewed; Journal article, 2017-03)Host–parasite systems have been useful in understanding coevolutionary patterns in sympatric species. Based on the exceptional interaction of the long‐lived and highly host‐specific freshwater pearl mussel (FPM; Margaritifera ... -
Enhancing pollination is more effective than increased conventional agriculture inputs for improving watermelon yields
(Journal article; Peer reviewed, 2020)Agricultural practices to improve yields in small‐scale farms in Africa usually focus on improving growing conditions for the crops by applying fertilizers, irrigation, and/or pesticides. This may, however, have limited ... -
Evolutionary effects of fishing gear on foraging behavior and life-history traits
(Peer reviewed; Journal article, 2018-11)Fishing gears are designed to exploit the natural behaviors of fish, and the concern that fishing may cause evolution of behavioral traits has been receiving increasing attention. The first intuitive expectation is that ... -
An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L.
(Journal article; Peer reviewed, 2023)Sexual size dimorphism (SSD) is caused by differences in selection pressures and life-history trade-offs faced by males and females. Proximate causes of SSD may involve sex-specific mortality, energy acquisition, and energy ... -
Food resource uncertainty shapes the fitness consequences of early spring onset in capital and income breeding migratory birds
(Journal article; Peer reviewed, 2022)Due to climate change, the timing of spring arrival and nesting onset in many migratory bird species have advanced. Earlier spring onsets prolong the available breeding period but can also deteriorate local conditions, ... -
From a crisis to an opportunity: Eight insights for doing science in the COVID‐19 era and beyond
(Journal article; Peer reviewed, 2020)The COVID-19 crisis has forced researchers in Ecology to change the way we work almost overnight. Nonetheless, the pandemic has provided us with several novel components for a new way of conducting science. In this perspective ... -
Genetic response to human-induced habitat changes in the marine environment: A century of evolution of European sprat in Landvikvannet, Norway
(Journal article; Peer reviewed, 2021)Habitat changes represent one of the five most pervasive threats to biodiversity. However, anthropogenic activities also have the capacity to create novel niche spaces to which species respond differently. In 1880, one ... -
Germination and seedling growth of Calluna vulgaris is sensitive to regional climate, heathland succession, and drought
(Journal article; Peer reviewed, 2023)The coastal heathlands of Northwest Europe are highly valued cultural landscapes, that are critically endangered due to land use and climatic changes, such as increased frequency and severity of drought events. Our study ... -
Inclusion of juvenile stages improves diversity assessment and adds to our understanding of mite ecology – A case study from mires in Norway
(Journal article; Peer reviewed, 2022)Arachnid orders, Mesostigmata, Trombidiformes, and Sarcoptiformes, commonly known as ‘mites’, are abundant in mires, both as adults and as juveniles. However, due to the challenges of identification, the juvenile forms are ... -
An innovative approach to using an intensive field course to build scientific and professional skills
(Journal article; Peer reviewed, 2022)This paper reports on the design and evaluation of Field Studies in Functional Ecology (FSFE), a two-week intensive residential field course that enables students to master core content in functional ecology alongside ... -
A long-term study of size variation in Northern Goshawk Accipiter gentilis across Scandinavia, with a focus on Norway
