Modelling the Effects of Forest use Change on Brownification of Finnish Rivers under Atmospheric Pressure
(Journal article; Peer reviewed, 2024)Browning of surface waters due to increased terrestrial loading of dissolved organic matter (DOM) is observed across the Northern Hemisphere. The effects influence several ecosystem services from freshwater productivity ... -
Importance of environmental signals for cardiac morphological development in Atlantic salmon
(Peer reviewed; Journal article, 2024)The hearts of salmonids display remarkable plasticity, adapting to various environmental factors that influence cardiac function and demand. For instance, in response to cold temperature, the salmonid heart undergoes growth ... -
Successful large-scale and long-term kelp forest restoration by culling sea urchins with quicklime and supported by crab predation
(Journal article; Peer reviewed, 2024)In 2013, a large scale (70 hectare) kelp forest restoration experiment was conducted in a sea urchin barren that had been stable for 45 years. We used 200 tons of quicklime to eradicate the sea urchin population. Kelp ... -
Advancing consistent socio-economic monitoring of coastal ecosystem restoration through collaborative metric development
(Journal article; Peer reviewed, 2024)Ecological restoration programs increasingly aim to provide socio-economic and environmental benefits. However, monitoring of socio-economic outcomes of these programs lags behind monitoring of ecological outcomes. ... -
The interaction between plastics and microalgae affects community assembly and nutrient availability
(Journal article; Peer reviewed, 2024)The presence of plastics and microplastics in water environments has raised concerns for potential negative impacts. The broader ecological implications for ecosystem functioning are, however, still unknown. The interaction ... -
