[HTML][HTML] The effects of oil spills on marine fish: Implications of spatial variation in natural mortality

Ø Langangen, E Olsen, LC Stige, J Ohlberger… - Marine Pollution …, 2017 - Elsevier
The effects of oil spills on marine biological systems are of great concern, especially in
regions with high biological production of harvested resources such as in the Northeastern …

Density‐and size‐dependent mortality in fish early life stages

…, G Ottersen, L Ciannelli, Ø Langangen… - Fish and …, 2019 - Wiley Online Library
The importance of survival and growth variations early in life for population dynamics depends
on the degrees of compensatory density dependence and size dependence in survival at …

[HTML][HTML] Contrasting effects of rising temperatures on trophic interactions in marine ecosystems

…, G Reygondeau, LC Stige, Ø Langangen - Scientific Reports, 2019 - nature.com
In high-latitude marine environments, primary producers and their consumers show seasonal
peaks of abundance in response to annual light cycle, water column stability and nutrient …

Effect of a fish stock's demographic structure on offspring survival and sensitivity to climate

LC Stige, NA Yaragina, Ø Langangen… - Proceedings of the …, 2017 - National Acad Sciences
Commercial fishing generally removes large and old individuals from fish stocks, reducing
mean age and age diversity among spawners. It is feared that these demographic changes …

Individual heterogeneity in life histories and eco‐evolutionary dynamics

Y Vindenes, Ø Langangen - Ecology letters, 2015 - Wiley Online Library
Individual heterogeneity in life history shapes eco‐evolutionary processes, and unobserved
heterogeneity can affect demographic outputs characterising life history and population …

Stage‐specific biomass overcompensation by juveniles in response to increased adult mortality in a wild fish population

J Ohlberger, Ø Langangen, E Edeline, D Claessen… - Ecology, 2011 - Wiley Online Library
Recently developed theoretical models of stage‐structured consumer–resource systems have
shown that stage‐specific biomass overcompensation can arise in response to increased …

Age structure affects population productivity in an exploited fish species

J Ohlberger, Ø Langangen, LC Stige - Ecological Applications, 2022 - Wiley Online Library
Long‐term changes in the age and size structure of animal populations are well documented,
yet their impacts on population productivity are poorly understood. Fishery exploitation can …

Effects of climate change on trait-based dynamics of a top predator in freshwater ecosystems

…, E Edeline, J Ohlberger, Ø Langangen… - The American …, 2014 - journals.uchicago.edu
Predicted universal responses of ectotherms to climate warming include increased maximum
population growth rate and changes in body size through the temperature-size rule. …

Six decades of pike and perch population dynamics in Windermere

Ø Langangen, E Edeline, J Ohlberger, IJ Winfield… - Fisheries …, 2011 - Elsevier
We use six decades of catch-at-age data for perch (Perca fluviatilis) and pike (Esox lucius)
in Windermere (UK) to estimate age- and sex-specific population sizes, natural mortalities …

[HTML][HTML] A standard protocol for describing the evaluation of ecological models

…, F Fransner, C Hansen, B Husson, Ø Langangen… - Ecological …, 2022 - Elsevier
Numerical models of ecological systems are increasingly used to address complex environmental
and resource management questions. One challenge for scientists, managers, and …
