Migrating silver eels return from the sea to the river of origin after a false start
(Peer reviewed; Journal article, 2021)The European eel’s singular spawning migration from European waters towards the Sargasso Sea remains elusive, including the early phase of migration at sea. During spawning migration, the movement of freshwater resident ... -
Atlantic Puffin Fratercula arctica fishing in a freshwater lake to feed its chick
(Peer reviewed; Journal article, 2021)We present details for the observation of an adult Atlantic Puffin Fratercula arctica collecting food in Lake Linnévatnet (78°02’N 13°48’E), the second largest freshwater lake in the Svalbard archipelago, on 11 August 2020. ... -
Changes in wetland habitat use by waterbirds wintering in Czechia are related to diet and distribution changes
(Peer reviewed; Journal article, 2021)1. Understanding species habitat use and factors affecting changes in their distribu-tions are necessary to promote the conservation of any biological community. We evaluated the changes in wetland use of the non- breeding ... -
First circumpolar assessment of Arctic freshwater phytoplankton and zooplankton diversity: Spatial patterns and environmental factors
(Peer reviewed; Journal article, 2021)1. Arctic freshwaters are facing multiple environmental pressures, including rapid climate change and increasing land-use activities. Freshwater plankton assemblages are expected to reflect the effects of these stressors ... -
Fire and herbivory drive fungal and bacterial communities through distinct above- and belowground mechanisms
(Peer reviewed; Journal article, 2021)Fire and herbivory are important natural disturbances in grassy biomes. Both drivers are likely to influence be- lowground microbial communities but no studies have unravelled the long-term impact of both fire and herbiv- ... -
Handbook of field sampling for multi-taxon biodiversity studies in European forests
(Peer reviewed; Journal article, 2021)Forests host most terrestrial biodiversity and their sustainable management is crucial to halt biodiversity loss. Although scientific evidence indicates that sustainable forest management (SFM) should be assessed by ... -
Contrasting structural complexity diferentiate hunting strategy in an ambush apex predator
(Peer reviewed; Journal article, 2021)Structural complexity is known to influence prey behaviour, mortality and population structure, but the effects on predators have received less attention. We tested whether contrasting structural complexity in two newly ... -
Fading opportunities for mitigating agriculture-environment trade-offs in a south American deforestation hotspot
(Peer reviewed; Journal article, 2021)Strong trade-offs between agriculture and the environment occur in deforestation frontiers, particularly in the world's rapidly disappearing tropical and subtropical dry forests. Pathways to mitigate these trade-offs are ... -
An assessment of relative habitat use as a metric for species’ habitat association and degree of specialization
(Peer reviewed; Journal article, 2021)In order to understand species’ sensitivity to habitat change, we must correctly determine if a species is associated with a habitat or not, and if it is associated, its degree of specialization for that habitat. However, ... -
Transformative governance of biodiversity: insights for sustainable development
(Peer reviewed; Journal article, 2021)While there is much debate on transformative change amongacademics and policymakers, the discussion on how to governsuch change is still in its infancy. This article argues thattransformative governance is needed to enable ... -
Predation on livestock as an indicator of drastic prey decline? The indirect effects of an African swine fever epidemic on predator–prey relations in Poland
(Peer reviewed; Journal article, 2021)ABSTRACT The gray wolf (Canis lupus) is one of the most conflictual mammals in Europe. Wild boar (Sus scrofa) are an essential part of gray wolf diet in central Europe, but after the emergence of African swine fever (ASF) ... -
Hunting harvest data in Sweden indicate precipitous decline in the native mountain hare subspecies Lepus timidus sylvaticus (heath hare)
(Peer reviewed; Journal article, 2021)Brown hare (Lepus europaeus) seems to outcompete mountain hare (L. timidus) wherever the two species co-occur, but few studies have validated or even addressed this issue. In southern Sweden, the distribution of non-native ... -
Modelling the downstream longitudinal effects of frequent hydropeaking on the spawning potential and stranding susceptibility of salmonids
(Peer reviewed; Journal article, 2021)Hydropower plant operating conditions are expected to change to be more in tandem with intermittent power production so as to meet the requirements of the Paris Agreement, which in turn may negatively impact ecolog- ical ... -
Soundscapes predict species occurrence in tropical forests
(Peer reviewed; Journal article, 2021)Accurate occurrence data is necessary for the conservation of keystone or endangered species, but acquiring it is usually slow, laborious and costly. Automated acoustic monitoring offers a scalable alternative to manual ... -
Infection by the cestodes Triaenophorus crassus and Diphyllobothrium spp. in a polymorphic whitefish population
(Peer reviewed; Journal article, 2021)The whitefish (Coregonus lavaretus s.l.) stock in Lake Femunden, Norway, includes three morphs: deepwater spawning (D-), river spawning (R-) and shallow water spawning (S-) whitefish. Infections by Diphyllobothrium spp. ... -
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 ... -
Model-based decomposition of environmental, spatial and species-interaction effects on the community structure of common fish species in 772 European lakes
(Peer reviewed; Journal article, 2021)Aim: We tested whether there is a strong effect of species interactions on assembly of local lake fish communities, in addition to environmental filters and dispersal. Location: Seven hundred and seventy-two European lakes ... -
Maturation in Atlantic salmon (Salmo salar, Salmonidae): a synthesis of ecological, genetic, and molecular processes
(Peer reviewed; Journal article, 2021)Over the past decades, Atlantic salmon (Salmo salar, Salmonidae) has emerged as a model system for sexual maturation research, owing to the high diversity of life history strategies, knowledge of trait genetic architecture, ... -
Seasonal and elevational variability in the induction of specialized compounds from mountain birch (Betula pubescens var. pumila) by winter moth larvae (Operophtera brumata)
(Peer reviewed; Journal article, 2021)The mountain birch [Betula pubescens var. pumila (L.)] forest in the Subarctic is periodically exposed to insect outbreaks, which are expected to intensify due to climate change. To mitigate abiotic and biotic stresses, ... -
Values, Beliefs, Norms, and Conservation-Oriented Behaviors toward Native Fish Biodiversity in Rivers: Evidence from Four European Countries
(Peer reviewed; Journal article, 2021)Riverine biodiversity in Europe is under threat from a range of anthropogenic factors. Key to effective biodiversity conservation is the public’s willingness to support restoration efforts. Based on value-belief-norm (VBN) ...
