Fish zona radiata (eggshell) protein: A sensitive biomarker for environmental estrogens
(Peer reviewed; Journal article, 1997-04)Environmental estrogens have recently caused great concern because of their ability to mimic natural hormones and influence vital endocrine functions in humans and wildlife. The induction of vitellogenin (Vtg) synthesis ... -
Fisheries in the Drylands of Sub-Saharan Africa – “Fish come with the rains”. Building resilience for fisheries-dependent livelihoods to enhance food security and nutrition in the drylands
(FAO Fisheries and Aquaculture Circulars ; 1118, Book, 2016)Dryland areas cover more than half of sub-Saharan Africa and are home to nearly 50 percent of its populations, who depend on agriculture (including livestock, crops and fisheries) as their main livelihood strategy. Sporadic ... -
Fisheries Surveys Are Essential Ocean Observing Programs in a Time of Global Change: A Synthesis of Oceanographic and Ecological Data From U.S. West Coast Fisheries Surveys
(Journal article; Peer reviewed, 2022)As climate change and other anthropogenic impacts on marine ecosystems accelerate in the 21st century, there is an increasing need for sustained ocean time series. A robust and collaborative network of regional monitoring ... -
Fisheries, the inverted food pyramid
(Peer reviewed; Journal article, 2015-12-13)A global assessment of fishing patterns and fishing pressure from 110 different Ecopath models, representing marine ecosystems throughout the world and covering the period 1970–2007, show that human exploitation across ... -
Fisheries-induced evolution
(Peer reviewed; Journal article, 2015-12)Increased mortality from fishing is expected to favor faster life histories, realized through earlier maturation, increased reproductive investment, and reduced postmaturation growth. There is also direct and indirect ... -
Fisheries-induced evolution in morphology: a selection experiment on the Trinidadian guppy (Poecilia reticulata)
(Master thesis, 2016-06-01)For the past century, the human population has been growing, and the human technology has been advancing, both at historically-unprecedented rates. As a result, the overall impact of human activities on the lives and deaths ... -
Fishes in a changing world: learning from the past to promote sustainability of fish populations
(Journal article; Peer reviewed, 2018)Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, ... -
Fishing for answers

Five reasons to take the precautionary approach to deep sea exploitation
(Journal article, 2023)Extractive activities in the deep sea are poised to advance faster than the science needed to evaluate risks. Here, we call for a strong precautionary approach in developing these industries. -

Flesh quality of Atlantic salmon smolts reared at different temperatures and photoperiods
(Peer reviewed; Journal article, 2019)Possible interactive effects of temperature and photoperiod on flesh quality in Atlantic salmon post‐smolts were studied. Juvenile (initial mean weight 96.0 g ± 3.1 SEM ) Atlantic salmon were reared at six different ... -
Flexible behaviour in a mesopelagic fish (Maurolicus muelleri)
(Journal article; Peer reviewed, 2021)Variability of mesopelagic scattering layers is often attributed to environmental conditions or multi-species layer composition. Yet, little is known about variation in behaviour among the individuals forming scattering ... -
The flickering connectivity system of the north Andean páramos
(Peer reviewed; Journal article, 2019-06-13)Aim: To quantify the effect of Pleistocene climate fluctuations on habitat connectivity across páramos in the Northern Andes. Location: Northern Andes. Methods: The unique páramos habitat underwent dynamic shifts in elevation ... -
Flow Cytometric Analysis of Bacterial Protein Synthesis: Monitoring Vitality After Water Treatment
(Journal article; Peer reviewed, 2021)Bacterial vitality after water disinfection treatment was investigated using bio-orthogonal non-canonical amino acid tagging (BONCAT) and flow cytometry (FCM). Protein synthesis activity and DNA integrity (BONCAT–SYBR ... -
Flow cytometric quantification of viruses in activated sludge
(Peer reviewed; Journal article, 2015-10-18)Viruses may play a critical role in the microbial dynamics of activated sludge systems; however the difficulty of their quantification makes long term and large scale studies costly, timely and challenging. Thus a flow ... -
Flower morphology variation in five species of Penstemon (Plantaginaceae) displaying Hymenoptera pollination syndrome
(Journal article; Peer reviewed, 2023)Background: Geographic distance promotes phenotypic variation by facilitating environmental distance, limiting gene flow, and exposing plants to different pollen vectors. Therefore, understanding how plant morphology changes ... -
Food characteristics and territory habitat selection in Lapland longspurs Calcarius lapponicus in the early part of the breeding season at Hardangervidda, southern Norway
(Master thesis, 2017-05-04)Climate change currently affects the whole globe. Especially tundra and alpine areas are expected to change in the coming decades, affecting the species which today inhabits these areas. The Lapland longspur Calcarius ... -
Food intake, growth, and expression of neuropeptides regulating appetite in clown anemonefish (Amphiprion ocellaris) exposed to predicted climate changes
(Journal article; Peer reviewed, 2021)The clown anemonefish (Amphiprion ocellaris) is a common model species in studies assessing the impact of climate changes on tropical coral fish physiology, metabolism, growth, and stress. However, the basic endocrine ... -
Food resource uncertainty shapes the fitness consequences of early spring onset in capital and income breeding migratory birds
(Journal article; Peer reviewed, 2022)Due to climate change, the timing of spring arrival and nesting onset in many migratory bird species have advanced. Earlier spring onsets prolong the available breeding period but can also deteriorate local conditions, ... -
