Airborne laser scanning reveals uniform responses of forest structure to moose (Alces alces) across the boreal forest biome
Petersen, Tanja Kofod; Kolstad, Anders Lorentzen; Kouki, Jari; Leroux, Shawn J.; Potvin, Lynette R.; Tremblay, Jean-Pierre; Wallgren, Märtha; Widemo, Fredrik; Cromsigt, Joris P. G. M.; Courtois, Coline; Austrheim, Gunnar; Gosse, John; den Herder, Michael; Hermanutz, Luise; Speed, James David Mervyn (Peer reviewed; Journal article, 2023)1. The moose Alces alces is the largest herbivore in the boreal forest biome, where it can have dramatic impacts on ecosystem structure and dynamics. Despite the importance of the boreal forest biome in global carbon ... -
Biodiversity dynamics in urban areas under changing land-uses
Petersen, Tanja Kofod (Doctoral theses at NTNU;2021:107, Doctoral thesis, 2021)Ecology goes to town Urbanisation is increasing worldwide, but as urban expansion inevitably happens at the cost of other ecosystems, understanding how this will affect biodiversity is crucial. Especially if we wish to ... -
Can plant traits predict seed dispersal probability via red deer guts, fur, and hooves?
Petersen, Tanja Kofod; Bruun, Hans Henrik (Journal article; Peer reviewed, 2019)Seed dispersal by mammals provides functional connectivity between isolated plant habitat patches. Across much of Europe, red deer (Cervus elaphus) populations are growing steadily, potentially leading to increasing ... -
Changes in the use of agricultural land in an urban municipality
Huso, Eli Kristin (Master thesis, 2021)Sammendrag Jordbruksareal er utsatt for press til andre formål enn jordbruk i urbane områder, på grunn av populasjonsvekst og urbanisering. Dette skyldes økt etterspørsel etter areal til boliger, infrastruktur, industri ... -
Climate and land-use drive the functional composition of vascular plant assemblages across Norway
Petersen, Tanja Kofod; Vuorinen, Katariina Elsa M; Bendiksby, Mika; Speed, James David Mervyn (Peer reviewed; Journal article, 2022)Traditionally, biogeography has described the distribution of species. But as plant functional traits and functional diversity underpin ecosystem dynamics, understanding drivers of functional diversity at biogeographical ... -
Competitors and ruderals go to town: plant community composition and function along an urbanisation gradient
Petersen, Tanja Kofod; Speed, James David Mervyn; Grøtan, Vidar; Austrheim, Gunnar (Journal article; Peer reviewed, 2021)Urbanisation is expected to function as a filter for plant species by changing the physiochemical environment, causing species turnover along an urbanisation gradient. Analyses of the functional traits of species characteristic ... -
A regionally coherent ecological fingerprint of climate change, evidenced from natural history collections
Speed, James David Mervyn; Evankow, Ann; Petersen, Tanja Kofod; Ranke, Peter Sjolte; Nilsen, Nellie Henriette; Turner, Grace Winifred; Aagaard, Kaare; Bakken, Torkild; Davidsen, Jan Grimsrud; Dunshea, Glenn; Hassel, Kristian; Finstad, Anders Gravbrøt; Husby, Magne; Hårsaker, Karstein; Koksvik, Jan Ivar; Prestø, Tommy; Vange, Vibekke (Peer reviewed; Journal article, 2022)Climate change has dramatic impacts on ecological systems, affecting a range of ecological factors including phenology, species abundance, diversity, and distribution. The breadth of climate change impacts on ecological ... -
Species data for understanding biodiversity dynamics: The what, where and when of species occurrence data collection
Petersen, Tanja Kofod; Speed, James David Mervyn; Grøtan, Vidar; Austrheim, Gunnar (Peer reviewed; Journal article, 2021)1. The availability and quantity of observational species occurrence records have greatly increased due to technological advancements and the rise of online portals, such as the Global Biodiversity Information Facility ... -
Urban aliens and threatened near-naturals: Land-cover affects the species richness of alien- and threatened species in an urban-rural setting
Petersen, Tanja Kofod; Speed, James David Mervyn; Grøtan, Vidar; Austrheim, Gunnar (Peer reviewed; Journal article, 2020)Urbanisation has strong effects on biodiversity patterns, but impacts vary among species groups and across spatial scales. From a local biodiversity management perspective, a more general understanding of species richness ... -
Urbanisation and land-cover change affect functional, but not compositional turnover of bird communities
Petersen, Tanja Kofod; Speed, James David Mervyn; Grøtan, Vidar; Frøyen, Yngve Karl; Austrheim, Gunnar (Peer reviewed; Journal article, 2023)Liver sinusoidal endothelial cells (LSECs) are fenestrated endothelial cells with a unique, high endocytic clearance capacity for blood-borne waste macromolecules and colloids. This LSEC scavenger function has been ...
