Ecdysteroid-dependent molting in tardigrades
(Journal article; Peer reviewed, 2024)Although molting is a defining feature of the most species-rich animal taxa—the Ecdysozoa, including arthropods, tardigrades, nematodes, and others1,2—its evolutionary background remains enigmatic. In pancrustaceans, such ... -
From aquaculture sludge to microalgae : Experimental analysis and value chain assessment
(Doctoral thesis, 2025-05-08)Denne studien evaluerer hvorvidt mikroalgedyrking og anaerob nedbrytning er biologisk og teknologisk egnet som avfallsbehandling av fiskeslam fra akvakultur. Videre ble denne verdikjedens miljøkonsekvenser, grunnleggende ... -
BOATSv2: New ecological and economic features improve simulations of high seas catch and effort
(Journal article; Peer reviewed, 2024)Climate change and industrial fishing are having profound effects on marine ecosystems. Numerical models of fish communities and their interaction with fishing can help assess the biogeochemical and socioeconomic dynamics ... -
Aquaporin-3a Dysfunction Impairs Osmoadaptation in Post-Activated Marine Fish Spermatozoa
(Journal article; Peer reviewed, 2024)Spermatozoon volume regulation is an essential determinant of male fertility competence in mammals and oviparous fishes. In mammals, aquaporin water channels (AQP3, -7 and -8) have been suggested to play a role in spermatozoon ... -
Untangling the Derogenes varicus species complex in Scandinavian waters and the Arctic: description of Derogenes abba n. sp. (Trematoda, Derogenidae) from Hippoglossoides platessoides and new host records for D. varicus (Müller, 1784) sensu stricto
(Journal article; Peer reviewed, 2024)Several studies have shown that the euryxenic trematode Derogenes varicus (Müller, 1784) represents a species complex. Four lineages have been designated (DV1–4) with the DV1 clade corresponding to D. varicus sensu stricto. ... -
Identifying the stand properties that support both high biodiversity and carbon storage in German forests
(Journal article; Peer reviewed, 2024)Forest ecosystems face threats related to human-driven degradation, climate change, and biodiversity loss. Addressing these challenges requires management strategies that combine biodiversity conservation with climate ... -
Engaging participatory mapping for co-management and spatial depiction of nature’s contributions to people in the Portuguese biosphere reserves
(Journal article; Peer reviewed, 2024)UNESCO Biosphere Reserves (BRs) are pivotal for studying and fostering sustainable interactions between people and nature. In this study, a public participatory geographical information system (PPGIS) approach was employed ... -
Understanding the Causes of Lumpfish (Cyclopterus lumpus) Mortality in Norwegian Hatcheries: Challenges and Opportunities
(Journal article; Peer reviewed, 2024)Lumpfish are broadly used as biological sea lice removers in Norwegian salmon farming and are mostly produced in hatcheries. To date, there is little systematic documentation on the mortality causes of lumpfish in hatcheries. ... -
Beyond the mosaic model of brain evolution: Rearing environment defines local and global plasticity
(Journal article; Peer reviewed, 2024)Comparative animal studies have identified a trend toward a more global structural organization as brains become larger, suggesting that brain regions grow in sync as predicted by the concerted model of brain evolution. ... -
How well do connectivity tools agree over the full life cycle? A case study of Irish Sea plaice Pleuronectes platessa Linnaeus, 1758
(Journal article; Peer reviewed, 2025)Adult plaice in the Irish Sea have distinct traits that reflect the spawning locations that could suggest a number of different populations. However, do connectivity pathways support this concept? Different tools are ... -
Ten simple rules to bridge ecology and palaeoecology by publishing outside palaeoecological journals
(Journal article; Peer reviewed, 2024)Owing to its specialised methodology, palaeoecology is often regarded as a separate field from ecology, even though it is essential for understanding long-term ecological processes that have shaped the ecosystems that ... -
Little seasonal variation of mercury concentrations and biomagnification in an Arctic pelagic food web
(Journal article; Peer reviewed, 2024)Despite numerous studies on mercury in Arctic biota, data from inaccessible, ice-covered regions − especially during the polar night and late winter − remain scarce. This scarcity results in poor understanding of the ... -
Long-term nitrogen deposition reduces the diversity of nitrogen-fixing plants
(Journal article; Peer reviewed, 2024)Biological nitrogen fixation is a fundamental part of ecosystem functioning. Anthropogenic nitrogen deposition and climate change may, however, limit the competitive advantage of nitrogen-fixing plants, leading to reduced ... -
Geohistorical insights into marine functional connectivity
(Journal article; Peer reviewed, 2024)Marine functional connectivity (MFC) refers to the flows of organic matter, genes, and energy that are caused by the active and passive movements of marine organisms. Occurring at various temporal and spatial scales, MFC ... -
Salmon lice biology, environmental factors, and smolt behaviour with implications for the Norwegian salmon farming management system: A critical review
(Journal article; Peer reviewed, 2025)In 2017, a new regulatory management system, the traffic light system (TLS), was implemented to estimate the effects of salmon lice from Norwegian salmon aquaculture on marine survival of wild Atlantic salmon and forms the ... -
Ex vivo and in vitro methods as a platform for studying anthropogenic effects on marine mammals: four challenges and how to meet them
(Journal article; Peer reviewed, 2024)Marine mammals are integral to global biodiversity and marine health through their roles in coastal, benthic, and pelagic ecosystems. Marine mammals face escalating threats from climate change, pollution, and human activities, ... -
Aqp4a and Trpv4 mediate regulatory cell volume increase for swimming maintenance of marine fish spermatozoa
(Journal article; Peer reviewed, 2024)Volume regulation is essential for cell homeostasis and physiological function. Amongst the sensory molecules that have been associated with volume regulation is the transient receptor potential vanilloid 4 (TRPV4), which ... -
Caldanaerobacter subterraneus subsp. keratinolyticus subsp. nov., a Novel Feather-Degrading Anaerobic Thermophile
(Journal article; Peer reviewed, 2024)Caldanaerobacter subterraneus subsp. keratinolyticus subsp. nov. strain KAk was isolated from a geothermal hot spring located in Kazakhstan. Growth occurred at temperatures ranging from 50 to 80 °C, with approximately 70 ... -
The importance of locally sourced data in identifying population trends: Insights from Iberian vertebrates
(Journal article; Peer reviewed, 2024)Understanding species population trends is key for assessing their conservation status and proposing measures to ensure their future persistence amid recent biodiversity loss. However, studies are reporting contrasting ... -
Spatio-temporal patterns in the biomass, species composition and nitrogen content of drift macroalgae in an urbanised coastal embayment
