Behaviour and habitat use of first-time migrant Arctic charr: novel insights from a subarctic marine area
(Peer reviewed; Journal article, 2023)Anadromous Arctic charr Salvelinus alpinus is a cold-adapted salmonid that is vul nerable to climate warming and anthropogenic activities including salmon farming, hydropower regulation, and pollution, which poses a ... -
Biotic homogenisation and differentiation as directional change in beta diversity: synthesising driver–response relationships to develop conceptualmodels across ecosystems
(Peer reviewed; Journal article, 2023)Biotic homogenisation is defined as decreasing dissimilarity among ecological assemblages sampled within a given spatial area over time. Biotic differentiation, in turn, is defined as increasing dissimilarity over time. ... -
Consequences of past climate change and recent human persecution on mitogenomic diversity in the arctic fox
(Journal article, 2019)Ancient DNA provides a powerful means to investigate the timing, rate and extent of population declines caused by extrinsic factors, such as past climate change and human activities. One species probably affected by both ... -
Do DOM quality and origin affect the uptake and accumulation of lipid-soluble contaminants in coastal filter feeders? An experimental simulation of teflubenzuron exposure to blue mussels
(Peer reviewed; Journal article, 2023)The increased export of terrestrial dissolved organic matter (terrDOM) to coastal marine ecosystems may affect local filter feeders and the local food web via the altered uptake of organic material and associated contaminants. ... -
Evaluating citizen science data for forecasting species responses to national forest management
(Journal article; Peer reviewed, 2016)The extensive spatial and temporal coverage of many citizen science datasets (CSD) makes them appealing for use in species distribution modeling and forecasting. However, a frequent limitation is the inability to validate ... -
Good-bye to tropical alpine plant giants under warmer climates? Loss of range and genetic diversity in Lobelia rhynchopetalum
(Journal article; Peer reviewed, 2016)The main aim of this paper is to address consequences of climate warming on loss of habitat and genetic diversity in the enigmatic tropical alpine giant rosette plants using the Ethiopian endemic Lobelia rhynchopetalum as ... -
Group 2i Isochrysidales produce characteristic alkenones reflecting sea ice distribution
(Peer reviewed; Journal article, 2021)Alkenones are biomarkers produced solely by algae in the order Isochrysidales that have been used to reconstruct sea surface temperature (SST) since the 1980s. However, alkenone based SST reconstructions in the northern ... -
Habitat suitability models based on opportunistic citizen science data: Evaluating forecasts from alternative methods versus an individual-based model
(Peer reviewed; Journal article, 2021)Aim: To evaluate the utility of opportunistic data from citizen science programmes for forecasting species distributions against forecasts with a model of individualbased population dynamics. Location: Sweden. Methods: We ... -
How many routes lead to migration? Comparison of methods to assess and characterize migratory movements
(Journal article; Peer reviewed, 2016)Summary 1. Decreasing rate of migration in several species as a consequence of climate change and anthropic pressure, together with increasing evidence of space-use strategies intermediate between residency and complete ... -
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 ... -
Learning from scientific literature: Can indicators for measuring success be standardized in “on the ground” restoration?
(Journal article, 2020)The Society for Ecological Restoration (SER) Primer identifies key ecosystem attributes for evaluating restoration outcome. Broad attribute categories could be necessary due to the large variety of restoration projects, but ... -
Linking public participation in scientific research to the indicators and needs of international environmental agreements
(Peer reviewed; Journal article, 2014)Different monitoring approaches collect data that can measure progress toward achieving global environmental indicators. These indicators can: (1) Audit management actions; (2) Inform policy choices; and (3) Raise awareness ... -
MICESE: A New Method Used for the Formulation of Key Messages from the Scientific Community for the EU Post 2020 Biodiversity Strategy
(Journal article, 2020)The European Union (EU) 2020 Biodiversity strategy will soon come to an end and may not have been as successful as envisioned. In the current context of the global biodiversity crisis, the European Commission, the research ... -
Numerical responses of saproxylic beetles to rapid increases in dead wood availability following geometrid moth outbreaks in sub-arctic mountain birch forest
(Peer reviewed; Journal article, 2014)Saproxylic insects play an important part in decomposing dead wood in healthy forest ecosystems, but little is known about their role in the aftermath of large-scale forest mortality caused by pest insect outbreaks. We ... -
Population genetics of the wolverine in Finland: the road to recovery?
(Peer reviewed; Journal article, 2020)After decades, even centuries of persecution, large carnivore populations are widely recovering in Europe. Considering the recent recovery of the wolverine (Gulo gulo) in Finland, our aim was to evaluate genetic variation ... -
Prevailing weather conditions and dietcomposition affect chick growth and survival in the black-legged kittiwake
(Journal article; Peer reviewed, 2018)To identify priorities for management of seabirds during the breeding season, it is important to understand the ecological mechanisms driving chick growth and survival. In this study, we examined the effects of diet and ... -
Sperm velocity in a promiscuous bird across experimental media of different viscosities
(Peer reviewed; Journal article, 2020)In species with internal fertilization, the female genital tract appears challenging to sperm, possibly resulting from selection on for example ovarian fluid to control sperm behaviour and, ultimately, fertilization. Few ... -
A test of local adaptation to drought in germination and seedling traits in populations of two alpine forbs across a 2000 mm/year precipitation gradient
(Peer reviewed; Journal article, 2023)Seed regeneration is a critical stage in the life histories of plants, affecting species' abilities to maintain local populations, evolve, and disperse to new sites. In this study, we test for local adaptations to drought ... -
Ultra-small bacteria and archaea exhibit genetic flexibility towards groundwater oxygen content, and adaptations for attached or planktonic lifestyles
(Journal article, 2023)Aquifers are populated by highly diverse microbial communities, including unusually small bacteria and archaea. The recently described Patescibacteria (or Candidate Phyla Radiation) and DPANN radiation are characterized ... -
