Invasive earthworms unlock arctic plant nitrogen limitation

Nature Communications, 2020
Arctic plant growth is predominantly nitrogen limited, where the slow nitrogen turnover in the soil is commonly attributed to the cold arctic climate. Here the authors show that the arctic plant-soil nitrogen cycling is also constrained by the lack of ...

Environmental Impacts—Freshwater Biogeochemistry [PDF]

, 2015
Climate change effects on freshwater biogeochemistry and riverine loads of biogenic elements to the Baltic Sea are not straight forward and are difficult to distinguish from other human drivers such as atmospheric deposition, forest and wetland management , eutrophication and hydrological alterations. Eutrophication is by far the most well-known factor

Environmental Impacts—Lake Ecosystems [PDF]

, 2016
The North Sea region contains a vast number of lakes; from shallow, highly eutrophic water bodies in agricultural areas to deep, oligotrophic systems in pristine high-latitude or high-altitude areas. These freshwaters and the biota they contain are highly vulnerable to climate change.

A high-resolution dynamic probabilistic material flow analysis of seven plastic polymers; A case study of Norway

Environment International, 2023
Plastic pollution has long been identified as one of the biggest challenges of the 21st century. To tackle this problem, governments are setting stringent recycling targets to keep plastics in a closed loop.

Understory functional groups and fire history but not experimental warming drive tree seedling performance in unmanaged boreal forests

Frontiers in Forests and Global Change, 2023
IntroductionSurvival and growth of tree seedlings are key processes of regeneration in forest ecosystems. However, little is known about how climate warming modulates seedling performance either directly or in interaction with understory vegetation and ...

Implementation of real-time source apportionment approaches using the ACSM–Xact–Aethalometer (AXA) setup with SoFi RT: the Athens case study [PDF]

Atmospheric Measurement Techniques
Air pollution, particularly from particulate matter (PM), poses serious public health and environmental risks, especially in urban areas. To address this, accurate source apportionment (SA) of PM is essential for effective air quality management ...

Molecular-scale description of interfacial mass transfer in phase-separated aqueous secondary organic aerosol [PDF]

Atmospheric Chemistry and Physics, 2021
Liquid–liquid phase-separated (LLPS) aerosol particles are known to exhibit increased cloud condensation nuclei (CCN) activity compared to well-mixed ones due to a complex effect of low surface tension and non-ideal mixing.

Contributions to local- and regional-scale formaldehyde concentrations [PDF]

Atmospheric Chemistry and Physics, 2019
Reducing ambient formaldehyde concentrations is a complex task because formaldehyde is both a primary and a secondary air pollutant, with significant anthropogenic and biogenic sources of volatile organic compound (VOC) precursor emissions.

Herbivores rescue diversity in warming tundra by modulating trait-dependent species losses and gains

Nature Communications, 2017
Warming can reduce plant diversity but it is unclear which species will be lost or gained under interacting global changes. Kaarlejärvi et al. manipulate temperature, herbivory and nutrients in a tundra system and find that herbivory maintains diversity ...
