High-resolution modeling of uplift landscapes can inform micrositing of wind turbines for soaring raptors
Hanssen, Frank Ole; May, Roelof Frans; Nygård, Torgeir (Journal article, 2020)Collision risk of soaring birds is partly associated with updrafts to which they are attracted. To ident ify the risk-enhancinglandscape features, a micrositing tool was developed to model orographic and thermal updraft ... -
Identifying high‑risk areas for introduction of new alien species: the case of the invasive round goby, a door‑knocker for Norway
Forsgren, Elisabet; Hanssen, Frank Ole (Peer reviewed; Journal article, 2022)Identifying new areas of colonisation by alien species is important for early detection and management. Door-knocker species pose problems for traditional predictive models because of lacking presence–absence data, but ... -
Legacies of Historical Exploitation of Natural Resources Are More Important Than Summer Warming for Recent Biomass Increases in a Boreal–Arctic Transition Region
Tømmervik, Hans; Bjerke, Jarle W.; Park, Taejin; Hanssen, Frank Ole; Myneni, Ranga B. (Peer reviewed; Journal article, 2019)Eurasian forest cover at high northern latitudes (> 67 N) has increased in recent decades due to stimulatory effects of global warming, but other factors may be important. The objective of this study is to compare the ... -
Match between soaring modes of black kites and the fine-scale distribution of updrafts
Santos, Carlos D.; Hanssen, Frank Ole; Muñoz, Antonio-Román; Onrubia, Alejandro; Wikelski, Martin; May, Roelof Frans; Silva, João P. (Journal article; Peer reviewed, 2017)Understanding how soaring birds use updrafts at small spatial scales is important to identify ecological constraints of movement, and may help to prevent conflicts between wind-energy development and the conservation of ... -
A natural antipredation experiment: predator control and reduced sea ice increases colony size in a long-lived duck
Hanssen, Sveinn Are; Moe, Børge; Bårdsen, Bård-Jørgen; Hanssen, Frank Ole; Gabrielsen, Geir W. (Peer reviewed; Journal article, 2013)Anthropogenic impact on the environment and wildlife are multifaceted and far-reaching. On a smaller scale, controlling for predators has been increasing the yield from local natural prey resources. Globally, human-induced ... -
Utilizing LiDAR data to map tree canopy for urban ecosystem extent and condition accounts in Oslo
Hanssen, Frank Ole; Barton, David Nicholas; Venter, Zander; Nowell, Megan Sara; Cimburova, Zofie (Peer reviewed; Journal article, 2021)LiDAR-based segmentation of urban tree canopies and their physical properties (canopy height, canopy diameter, 3D surface and volume) is a replicable, complementary and useful information source for urban ecosystem condition ... -
Wind turbines cause functional habitat loss for migratory soaring birds
Marques, Ana T.; Santos, Carlos D.; Hanssen, Frank Ole; Muñoz, Antonio-Román; Onrubia, Alejandro; Wikelski, Martin; Moreira, Francisco; Palmeirim, Jorge Manuel; Silva, João P. (Journal article; Peer reviewed, 2019)1 . Wind energy production has expanded to meet climate change mitigation goals, but negative impacts of wind turbines have been reported on wildlife. Soaring birds are among the most affected groups with alarming fatality ...
