Can Energy Depletion of Wild Atlantic Salmon Kelts Negotiating Hydropower Facilities Lead to Reduced Survival?
(Peer reviewed; Journal article, 2020)Repeat spawners constitute an important component of Atlantic salmon populations, but survival of post-spawning individuals (kelts) are often compromised by anthropogenic structures such as hydropower plants (HPPs). Potential ... -

Classifying grass-dominated habitats from remotely sensed data: The influence of spectral resolution, acquisition time and the vegetation classification system on accuracy and thematic resolution
(Peer reviewed; Journal article, 2020)Detailed maps of vegetation facilitate spatial conservation planning. Such information can be difficult to map from remotely sensed data with the detail (thematic resolution) required for ecological applications. For ... -

Sharing the neighbourhood: assessing the impact of kelp harvest on foraging behaviour of the European shag
(Peer reviewed; Journal article, 2020)Coastal kelp forest ecosystems create dynamic and productive habitats, supporting a wide range of epiphytic flora, invertebrates, fish and seabirds. Worldwide, kelp is harvested commercially, affecting kelp-associated ... -

Integrative taxonomy of the Changeable Hawk-Eagle Nisaetus cirrhatus complex (Accipitriformes: Accipitridae) in India
(Peer reviewed; Journal article, 2020)The Changeable Hawk-Eagle Nisaetus cirrhatus complex is represented by two taxa in mainland India: N. c. cirrhatus in the northern plains and peninsula and N. c. limnaeetus in the Himalayan foothills. Traditionally these ... -
Heart rate and swimming activity as stress indicators for Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)We investigated the relationship between telemetry measurements of heart rate and swimming activity and the physiological status in farmed Atlantic salmon (Salmo salar) to assess the potential to use telemetry measurements ... -
Selective removal of problem individuals as an environmentally responsible approach for managing shark bites on humans
(Peer reviewed; Journal article, 2020)Selective removal of problem individuals following shark bite incidents would be consistent with current management practices for terrestrial predators, and would be more effective and more environmentally responsible than ... -

Integration of a local fish market in Namibia with the global seafood trade: Implications for fish traders and sustainability
(Peer reviewed; Journal article, 2020)Within the last decades, globalization has changed the international seafood trade, allowing low-income countries to access markets in high-income countries and vice versa. Nevertheless, the effects of globalization are ... -
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 ... -
Focus on recent, present and future Arctic and boreal productivity and biomass changes
(Peer reviewed; Journal article, 2020)The reduction of cold temperature constraints on photosynthesis in recent decades has led to extended growing seasons and increased plant productivity (greening) in significant parts of Polar, Arctic and Boreal regions, ... -
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 ... -
Does defoliation frequency and severity influence plant productivity? The role of grazing management and soil nutrients
(Peer reviewed; Journal article, 2020)Rangeland management approaches, including rotational grazing, rely on assumptions about plant growth responses to the intensity, or severity (sward height) plus frequency, of defoliation. We tested these assumptions at ... -
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 ... -
