Long-range transcriptional regulation of vertebrate developmental genes and the evolution of genome architecture
(Doctoral thesis, 2008-09-12)Despite the recent massive progress in production of vertebrate genome sequence data and large-scale efforts to completely annotate the human genome, we still have scant knowledge of the principles that built genomes in ... -
Long-term change in a behavioural trait: truncated spawning distribution and demography in Northeast Arctic cod
(Peer reviewed; Journal article, 2015-04)Harvesting may be a potent driver of demographic change and contemporary evolution, which both may have great impacts on animal populations. Research has focused on changes in phenotypic traits that are easily quantifiable ... -
Long-term changes in life-history traits of Norwegian spring-spawning herring
(Doctoral thesis, 2019)Life-history traits are key determinants of populations’ dynamics. Those traits are susceptible to natural selection and are therefore sensitive to the mortality regime and the selection pattern a population experience. ... -
Long-Term Climate Regime Modulates the Impact of Short-Term Climate Variability on Decomposition in Alpine Grassland Soils
(Peer reviewed; Journal article, 2018-12)Decomposition of plant litter is an important process in the terrestrial carbon cycle and makes up approximately 70% of the global carbon flux from soils to the atmosphere. Climate change is expected to have significant ... -
Long-term disturbance dynamics and resilience of tropical peat swamp forests
(Peer reviewed; Journal article, 2015-01)1. The coastal peat swamp forests of Sarawak, Malaysian Borneo, are undergoing rapid conversion, predominantly into oil palm plantations. This wetland ecosystem is assumed to have experienced insignificant disturbance in ... -
Long-term dynamics of wadi trees in a hyper-arid cultural landscape
(Doctoral thesis, 2007-03-09)This study focuses on the long-term dynamics of wadi (dry river valley) trees, in particular Acacia tortilis (Forssk.) Hayne, in the hyper-arid Eastern Desert of Egypt. The project was motivated by the importance of drought ... -
Long-term ecological responses of a lowland dipterocarp forest to climate changes and nutrient availability
(Journal article; Peer reviewed, 2023)Understanding the long-term impact of projected climate change on tropical rainforests is critical given their central role in the Earth's system. Palaeoecological records can provide a valuable perspective on this problem. ... -
Long-term effects of environmentally relevant doses of 2,2’,4,4’,5,5’ hexachlorobiphenyl (PCB153) on neurobehavioural development, health and spontaneous behaviour in maternally exposed mice
(Peer reviewed; Journal article, 2011-01-13)Background: Polychlorinated biphenyls (PCBs) are widespread in the environment, human food and breast milk. Seafood is known to contain nutrients beneficial for the normal development and function of the brain, but also ... -
Long-term fire resilience of the Ericaceous Belt, Bale Mountains, Ethiopia
(Peer reviewed; Journal article, 2019)Fire is the most frequent disturbance in the Ericaceous Belt (ca 3000–4300 m.a.s.l.), one of the most important plant communities of tropical African mountains. Through resprouting after fire, Erica establishes a positive ... -
Long-term investigation of the ‘soft flesh’ condition in Northeast Atlantic mackerel induced by the myxosporean parasite Kudoa thyrsites (Cnidaria, Myxozoa): Temporal trends and new molecular epidemiological observations
(Journal article; Peer reviewed, 2022)Northeast Atlantic (NEA) mackerel (Scomber scombrus, Scombridae) represents an economically important target for the Norwegian pelagic fishing industry. Despite the commercial significance of NEA mackerel, little is known ... -
Long-term monitoring of a brown trout (Salmo trutta) population reveals kin-associated migration patterns and contributions by resident trout to the anadromous run
(Journal article; Peer reviewed, 2021)Background: In species showing partial migration, as is the case for many salmonid fishes, it is important to assess how anthropogenic pressure experienced by migrating individuals affects the total population. We focused ... -
Long-term Observations Reveal Environmental Conditions and Food Supply Mechanisms at an Arctic Deep-Sea Sponge Ground
(Journal article; Peer reviewed, 2021)Deep-sea sponge grounds are hotspots of benthic biomass and diversity. To date, very limited data exist on the range of environmental conditions in areas containing deep-sea sponge grounds and which factors are driving ... -
Long-term responses of benthic invertebrates to rotenone treatment
(Journal article; Peer reviewed, 2021)Biological invasions are regarded as one of the largest threats to native biodiversity. The eradication of alien invasive fish or parasites by culling of hosts is a controversial conservation strategy, particularly when ... -
Long-term trajectories of non-native vegetation on islands globally
(Journal article; Peer reviewed, 2023)Human-mediated changes in island vegetation are, among others, largely caused by the introduction and establishment of non-native species. However, data on past changes in non-native plant species abundance that predate ... -
Long-term trends in diatom diversity and palaeoproductivity: A 16 000-year multidecadal record from Lake Baikal, southern Siberia
(Journal article; Peer reviewed, 2022)Biological diversity is inextricably linked to community stability and ecosystem functioning, but our understanding of these relationships in freshwater ecosystems is largely based on short-term observational, experimental, ... -
Long-term welfare effects of repeated warm water treatments on Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2022)Warm water treatment has in recent years become widely used for ridding salmonids of sea lice in aquaculture although the consequences of the treatment for fish welfare are not adequately investigated. The objective of ... -
Longevity and growth of Acacia tortilis; insights from 14C content and anatomy of wood
(Peer reviewed; Journal article, 2007-06-15)Background: Acacia tortilis is a keystone species across arid ecosystems in Africa and the Middle East. Yet, its life-history, longevity and growth are poorly known, and consequently ongoing changes in tree populations ... -
Looking forward through the past: identification of 50 priority research questions in palaeoecology

Losing the ‘arms race’: multiresistant salmon lice are dispersed throughout the North Atlantic Ocean
(Journal article; Peer reviewed, 2021)Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in ... -
