Bat (Chiroptera) activity and community composition in contrasting agricultural landscapes and the adjacent Budongo forest reserve, Uganda
(Master thesis, 2010-06-01)Abstract. Human activities are causing a biodiversity crisis in all biomes of the Earth. As the world's population continues to grow, more land will be converted to agricultural land to meet the growing food demands, ... -
Comparing species-temperature relationships of arctic-alpine plants among three altitudinal transects in Svalbard
(Master thesis, 2008)Broad scale data has normally been used to predict vascular plant species responses to global climate change. The aim of this study is to investigate to what extent a high sampling resolution reveals local variations among ... -
Effects of gas supersaturation on migrating Atlantic salmon smolt (Salmo salar) in Evangervatnet
(Master thesis, 2016-11-21)Total dissolved gas supersaturation (TDGS) downstream of power plants may cause harmful effects on the fauna in many rivers. The harmful effects of TDGS are known as gas bubble disease (GBD). TDGS has been proposed as one ... -
Large mesopelagic fishes biomass and trophic efficiency in the open ocean
(Peer reviewed; Journal article, 2014-02-07)With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could be significantly larger ... -
Making predictions in a changing world: The benefits of individual-based ecology
(Peer reviewed; Journal article, 2015-12-17)Ecologists urgently need a better ability to predict how environmental change affects biodiversity. We examine individual-based ecology (IBE), a research paradigm that promises better a predictive ability by using ... -
On a hexactinellid sponge aggregation at the Great Meteor seamount (North-east Atlantic)
(Peer reviewed; Journal article, 2015-11)Hexactinellids or glass sponges constitute a predominantly deep-sea sponge group typically occurring at bathyal and abyssal depths. Some species form dense populations along the European and African continental slope but ... -
Thermal plasticity in farmed, wild and hybrid Atlantic salmon during early development: Has domestication caused divergence in low temperature tolerance?
(Peer reviewed; Journal article, 2016-02-16)Background: In the past three decades, millions of domesticated Atlantic salmon Salmo salar L. have escaped from farms into the wild. Their offspring display reduced survival in the natural environment, which demonstrates ...
