Age of European silver eels during a period of declining abundance in Norway
(Journal article, 2020)The European eel (Anguilla anguilla) is critically endangered throughout its range. Knowledge about age distribution of future spawners (silver eels) is essential to monitor the status and contribute to the recovery of ... -
Application of Landsat-derived vegetation trends over South Africa: Potential for monitoring land degradation and restoration
(Peer reviewed; Journal article, 2020)Monitoring vegetation change is important because the nature, extent and rate of change in key measures, such as plant biomass, cover and species composition, provides critical insight into broader environmental and land ... -
Assessing the resilient provision of ecosystem services by social-ecological systems: introduction and theory
(Journal article; Peer reviewed, 2017) -
Density-dependent selection and the maintenance of colour polymorphism in barn owls
(Peer reviewed; Journal article, 2022)The capacity of natural selection to generate adaptive changes is (according to the fundamental theorem of natural selection) proportional to the additive genetic variance in fitness. In spite of its importance for development ... -
Don't mind if I do: Arctic humpback whales respond to winter foraging opportunities before migration
(Peer reviewed; Journal article, 2023)Migration patterns are fundamentally linked to the spatio-temporal distributions of prey. How migrating animals canrespond to changes in their prey’s distribution and abundance remains largely unclear. During the ... -
Ecosystem Services and Opportunity Costs Shift SpatialPriorities for Conserving Forest Biodiversity
(Peer reviewed; Journal article, 2014)Inclusion of spatially explicit information on ecosystem services in conservation planning is a fairly new practice. This study analyses how the incorporation of ecosystem services as conservation features can affect ... -
Evolutionary change in metabolic rate of Daphnia pulicaria following invasion by the predator Bythotrephes longimanus
(Peer reviewed; Journal article, 2022)Metabolic rate is a trait that may evolve in response to the direct and indirect effects of predator-induced mortality. Predators may indirectly alter selection by lowering prey densities and increasing resource availability ... -
Extreme event impacts on CO2 fluxes across a range of high latitude, shrub-dominated ecosystems
(Peer reviewed; Journal article, 2020)The Arctic is experiencing an increased frequency of extreme events which can cause landscape-scale vegetation damage. Extreme event-driven damage is an important driver of the decline in vegetation productivity (termed ... -
Global analysis of seasonal changes in trematode infection levels reveals weak and variable link to temperature
(Peer reviewed; Journal article, 2023)Seasonal changes in environmental conditions drive phenology, i.e., the annual timing of biological events ranging from the individual to the ecosystem. Phenological patterns and successional abundance cycles have been ... -
The impact of leopards (Panthera pardus) on livestock losses and human injuries in a human-use landscape in Maharashtra, India
(Journal article, 2020)There are many ways in which large carnivores and humans interact in shared spaces. In this study we provide insights into human-leopard relationships in an entirely modified, human-dominated landscape inhabited by dense ... -
The legacy of forest disturbance on stream ecosystem functioning
(Peer reviewed; Journal article, 2021)1. Forest clearance is a pervasive disturbance worldwide, but many of its impacts are regarded as transient, diminishing in intensity as forest recovers. However, forests can take decades to centuries to recover after ... -
Occupancy versus colonization–extinction models for projecting population trends at different spatial scales
(Peer reviewed; Journal article, 2020)Understanding spatiotemporal population trends and their drivers is a key aim in population ecology. We further need to be able to predict how the dynamics and sizes of populations are affected in the long term by changing ... -
On fitness and partial migration in a large herbivore – migratory moose have higher reproductive performance than residents
(Journal article; Peer reviewed, 2016)Partially migratory populations comprise both resident and migratory individuals. Th ese tactics may coexist if their demographic contribution to future generations (i.e. fitness) are equal or vary temporally with environmental ... -
Predation or scavenging? Prey body condition influences decision-making in a facultative predator, the wolverine. Photo gallery
(Journal article; Peer reviewed, 2017)What determines whether a predator scavenges or kills its own prey? Using data on wolverines ( Gulo gulo ) in Scandinavia, we studied variation in diet and feeding strategies along a gradient of environmental productivity, ... -
Resources and predation: drivers of sociality in a cyclic mesopredator
(Peer reviewed; Journal article, 2022)In socially fexible species, the tendency to live in groups is expected to vary through a trade-of between costs and benefts, determined by ecological conditions. The Resource Dispersion Hypothesis predicts that group size ... -
Revealing hidden insect–fungus interactions; moderately specialized, modular and anti-nested detritivore networks
(Journal article; Peer reviewed, 2018)Ecological networks are composed of interacting communities that influence ecosystem structure and function. Fungi are the driving force for ecosystem processes such as decomposition and carbon sequestration in terrestrial ... -
The roles of humans and apex predators in sustaining ecosystem structure and function: Contrast, complementarity and coexistence
(Peer reviewed; Journal article, 2022)In nearly every ecosystem, human predators (hunters and fishers) exploit animals at extraordinarily high rates, as well as target different age classes and phenotypes, compared to other apex predators. Demographically ... -
Setting reference levels and limits for good ecological condition in terrestrial ecosystems – Insights from a case study based on the IBECA approach
(Journal article, 2020)Effective evidence-based nature conservation and habitat management relies on developing and refining our methodological toolbox for detecting critical ecological changes at an early stage. This requires not only optimizing ... -
Top-down control of a marine mesopredator: Increase in native white-tailed eagles accelerates the extinction of an endangered seabird population
(Peer reviewed; Journal article, 2023)1. Bottom-up control is an important regulator of marine mesopredators such as seabirds. The prevalence of top-down control on these species is however less well understood. In particular, how native predators affect seabird ... -
Towards a systematics of ecodiversity: The EcoSyst framework
(Journal article, 2020)Background Although a standard taxonomy of organisms has existed for nearly 300 years, no consensus has yet been reached on principles for systematization of ecological diversity (i.e., the co‐ordinated variation of abiotic ...
