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