Population and distribution of beavers Castor fiber and Castor canadensis in Eurasia
(Peer reviewed; Journal article, 2020)1. A century ago, overhunting had reduced Eurasian beaver Castor fiber populations to c. 1200 animals in scattered refugia from France to Mongolia. Reintroductions and natural spread have since restored the species to large ... -
Spreading or Gathering? Can Traditional Knowledge be a Resource to Tackle Reindeer Diseases Associated with Climate Change?
(Peer reviewed; Journal article, 2020)This paper inquires whether reindeer herders’ traditional knowledge (TK) provides a reservoir of precaution and adaptation possibilities that may be relevant to counteract climate change. As our core example, we used the ... -
Consequences of barriers and changing seasonality on population dynamics and harvest of migratory ungulates
(Peer reviewed; Journal article, 2020)Many animal populations providing ecosystem services, including harvest, live in seasonal environments and migrate between seasonally distinct ranges. Unfortunately, two major sources of human-induced global change threaten ... -
Spatiotemporal tourism pattern in a large reindeer (Rangifer tarandus tarandus) range as an important factor in disturbance research and management
(Peer reviewed; Journal article, 2020)Tourism and recreation in protected areas may compromise conservation values if their forms and volumes exceed the area’s tolerance. Disturbance-sensitive species such as wild and semi-domestic reindeer (Rangifer tarandus ... -

Mortality of Atlantic salmon after catch and release angling: assessment of a recreational Atlantic salmon fishery in a changing climate
(Peer reviewed; Journal article, 2020)Human activities have the potential to accelerate population-level decline by contributing to climate warming and decreasing the capacity of species to survive warming temperatures. Here we build a predictive model to test ... -

Evaluating the use of local ecological knowledge (LEK) in determining habitat preference and occurrence of multiple large carnivores
(Peer reviewed; Journal article, 2020)Understanding habitat preferences and distribution of threatened species is a cornerstone of conservation, however many of the techniques available can be resource intensive. One cost-effective method is by collecting ... -
Evaluating cumulative effects of small scale hydropower development using GIS modelling and representativeness assessments
(Journal article, 2020)Assessing cumulative effects are a vital task for strategic environmental assessments (SEA) but lack of consistent methodology has hampered the development and implementation of useful tools. We present a model for GIS and ... -
Foraging tactics in dynamic sea-ice habitats affect individual state in a long-ranging seabird
(Peer reviewed; Journal article, 2020)1. Individual heterogeneity in diet and foraging behaviour is common in wild animal populations, and can be a strong determinant of how populations respond to environmental changes. Within populations, variation in ... -
Towards a systematics of ecodiversity: The EcoSyst framework
(Journal article, 2020)Background Although a standard taxonomy of organisms has existed for nearly 300 years, no consensus has yet been reached on principles for systematization of ecological diversity (i.e., the co‐ordinated variation of abiotic ... -
COVID-19 lockdowns cause global air pollution declines
(Peer reviewed; Journal article, 2020)The lockdown response to coronavirus disease 2019 (COVID-19) has caused an unprecedented reduction in global economic and transport activity. We test the hypothesis that this has reduced tropospheric and ground-level air ... -
Paint it black: Efficacy of increased wind turbine rotor blade visibility to reduce avian fatalities
(Peer reviewed; Journal article, 2020)As wind energy deployment increases and larger wind-power plants are considered, bird fatalities through collision with moving turbine rotor blades are expected to increase. However, few (cost-) effective deterrent or ...
