Inequitable distribution of plastic benefits and burdens on economies and public health
(Peer reviewed; Journal article, 2023)Plastic heterogeneously affects social systems – notably human health and local and global economies. Here we discuss illustrative examples of the benefits and burdens of each stage of the plastic lifecycle (e.g., macroplastic ... -
Inferring heavy tails of flood distributions through hydrograph recession analysis
(Peer reviewed; Journal article, 2023)Floods are often disastrous due to underestimation of the magnitude of rare events. Underestimation commonly happens when the magnitudes of floods follow a heavy-tailed distribution, but this behavior is not recognized and ... -
Influence of climate change and pesticide use practices on the ecological risks of pesticides in a protected Mediterranean wetland: A Bayesian network approach
(Peer reviewed; Journal article, 2023)Pollution by agricultural pesticides is one of the most important pressures affecting Mediterranean coastal wetlands. Pesticide risks are expected to be influenced by climate change, which will result in an increase of ... -
Influence of dense macrophyte vegetation and total gas saturation on the performance of acoustic telemetry
(Peer reviewed; Journal article, 2022)Acoustic telemetry is widely used as a method for high resolution monitoring of aquatic animal movement to investigate relationships between individual animals and their environment. In shallow freshwater ecosystem, aquatic ... -
Influence of flood risk characteristics on flood insurance demand: a comparison between Germany and the Netherlands
(Journal article; Peer reviewed, 2013)The existence of sufficient demand for insurance coverage against infrequent losses is important for the adequate function of insurance markets for natural disaster risks. This study investigates how characteristics of ... -
The influence of hydrodynamic exposure on carbon storage and nutrient retention in eelgrass (Zostera marina L.) meadows on the Swedish Skagerrak coast
(Journal article; Peer reviewed, 2020)Cold-temperate seagrass (Zostera marina) meadows provide several important ecosystem services, including trapping and storage of sedimentary organic carbon and nutrients. However, seagrass meadows are rapidly decreasing ... -
Influence of larval transport and temperature on recruitment dynamics of North Sea cod (Gadus morhua) across spatial scales of observation
(Peer reviewed; Journal article, 2020)The survival of fish eggs and larvae, and therefore recruitment success, can be critically affected by transport in ocean currents. Combining a model of early‐life stage dispersal with statistical stock–recruitment models, ... -
Influence of Riverine Input on Norwegian Coastal Systems
(Peer reviewed; Journal article, 2020)Coastal ecosystems are of high ecological and socioeconomic importance and are strongly influenced by processes from land, sea, and human activities. In this study, we present physical, chemical, and biological observations ... -
Influence of suspended sediment front on nutrients and phytoplankton dynamics off the Changjiang Estuary: A FVCOM-ERSEM coupled model experiment
(Peer reviewed; Journal article, 2020)High-turbidity water is a common feature in the estuary and inner shelf. Sediment suspension functions as a modulator that directly influences the interactions among nutrients, phytoplankton and other related ecosystem ... -
Influences of climate change on long-term time series of persistent organic pollutants (POPs) in Arctic and Antarctic biota
(Peer reviewed; Journal article, 2022)Time series of contaminants in the Arctic are an important instrument to detect emerging issues and to monitor the effectiveness of chemicals regulation, based on the assumption of a direct reflection of changes in primary ... -
