Observations of a White-tailed Eagle incubating eggs of a Greylag goose
(Others, 2023)Interspecific takeovers of nests are thought to be rare in birds. A female White-tailed Eagle Haliaeetus albicilla was observed incubating a nest of a Greylag Goose Anser anser with five eggs at Reinøya, Troms County, ... -
Observed and projected changes in urbanization and nature conservation in a typical fast growing city of Ethiopia, Jimma
(Peer reviewed; Journal article, 2023)Urbanization poses a signifcant threat to biodiversity, particularly in developing nations characterized by high rural–urban migration and inadequate urban planning that fails to consider nature conservation. Insufcient ... -
Occupancy versus colonization–extinction models for projecting population trends at different spatial scales
(Peer reviewed; Journal article, 2020)Understanding spatiotemporal population trends and their drivers is a key aim in population ecology. We further need to be able to predict how the dynamics and sizes of populations are affected in the long term by changing ... -
Occupancy-based monitoring of ungulate prey species in Thailand indicates population stability, but limited recovery
(Peer reviewed; Journal article, 2020)Longitudinal studies of wildlife are urgently needed in South-East Asia to understand population responses to the high poaching pressure that characterizes this region. We monitored population trends and habitat use of ... -
Occurrence and seasonality of Gyrodactylus salaris and G. salmonis (Monogenea) on Arctic char (Salvelinus alpinus (L.)) in the Fustvatnet lake, Northern Norway
(Peer reviewed; Journal article, 2023)Gyrodactylus spp. (Monogenea) were found on 16.9% (233 out of 1376) Arctic char, Salvelinus alpinus (L.), sampled from September 2010 to October 2011 in the Fustvatnet lake, Northern Norway. Two species were identified: ... -
The occurrence of the cold-water coral Lophelia pertusa (Desmophyllum pertusum) on Equinor oil and gas structures in the North Sea
(NINA Report;2457, Research report, 2024)This report has restricted access -
Occurrence of the European eel in lakes in the northern part of its distribution area is limited to low-altitude coastal areas, likely due to topographical conditions
(Peer reviewed; Journal article, 2019)With the decline of the European eel, protection measures in all parts of the eel’s distribution area may be increasingly important. Norway has a vast coastline (58°–71°N), but the distribution of eel has been largely ... -
Ocean climate and egg investment in the black-legged kittiwake Rissa tridactyla
(Journal article; Peer reviewed, 2017)Birds allocate substantial resources to their eggs during the laying period, resources also needed for other concurrent costly processes such as mate acquisition, nest building and site defence. Egg and clutch sizes may ... -
Ocean currents as a potential dispersal pathway for Antarctica’s most persistent non-native terrestrial insect
(Peer reviewed; Journal article, 2021)The non-native midge Eretmoptera murphyi is Antarctica’s most persistent non-native insect and is known to impact the terrestrial ecosystems. It inhabits by considerably increasing litter turnover and availability of soil ... -

Ocean-wide drivers of migration strategies and their influence on population breeding performance in a declining seabird
(Journal article; Peer reviewed, 2017)Which factors shape animals’ migration movements across large geographical scales, how different migratory strategies emerge between populations, and how these may affect population dynamics are central questions in ... -
Off the conservation radar: the hidden story of Europe’s tiny pea clams (Bivalvia: Sphaeriidae)
(Peer reviewed; Journal article, 2024)This study highlights the conservation problems faced by the tiny freshwater bivalves of the family Sphaeriidae, also known as pea, pill, or fingernail clams (or mussels) in Europe. Despite their global distribution, assumed ... -
Offshore oil rigs – a breeding refuge for Norwegian Black-legged Kittiwakes Rissa tridactyla?
(Peer reviewed; Journal article, 2020)In recent decades, the population of Black-legged Kittiwake Rissa tridactyla has declined substantially in most parts of the North Atlantic. Concurrently, there has been an increased urbanisation of the species, with ... -
