Anadromous salmonids begin life adapted to the freshwater environments of their natal streams before a developmental transition, known as smoltification, transforms them into marine-adapted fish. In wild, smoltification is photoperiod-regulated process, involving radical remodeling gill function cope with profound osmotic and immunological challenges seawater (SW) migration. While prior work has highlighted role specialized “mitochondrion-rich” cells (MRCs) accessory (ACs) in delivering this...

Atlantic salmon ( Salmo salar ) move from fresh- to seawater environments following a seasonally timed preparative transition called smoltification, which takes place under photoperiodic control in the freshwater environment. In masu Oncorhynchus masou ), coordination of sexual maturation is proposed involve fish-specific circumventricular organ, saccus vasculosus (SV), through its intrinsic opsin-based light sensitivity, thyrotrophin secretion and modulation deiodinase activity (TSH-DIO...

The spatial and temporal distribution of forage quality is among the most central factors affecting herbivore habitat selection. Yet, for high latitude areas, quantity has been found to be more important than quality. Studies on large ungulate foraging patterns are faced with methodological challenges in both assessing animal movements at scale distribution, relevant metrics. Here we use first-passage time analyses assess how reindeer relate measured as phenology cover growth forms along...

Abstract Question: Different plant growth forms may have distinctly different functioning in ecosystems. Association of phenological patterns with form will therefore help elucidate the role phenology an ecosystem. We ask whether common vascular plants differ terms vegetative and flowering phenology, if such differences are consistent across environmental gradients caused by landscape‐scale topography. Location: A high‐latitude alpine landscape Finnmark County, Norway (70°N). Methods:...

Several studies on endozoochory have established large herbivores as important for seed dispersal, yet no evaluated how is dependent ecological scale and context. Here we address effects of reindeer density in a hierarchical, multi‐scale study, encompassing several contexts. We found to vary with spatial scale. Higher densities at the level landscape areas, indexed through faeces abundance, were related both less species lower abundance emerging plants from faeces. In contrast, there was...

Across taxa, circadian control of physiology and behavior arises from cell-autonomous oscillations in gene expression, governed by a networks so-called 'clock genes', collectively forming transcription-translation feedback loops. In modern vertebrates, these contain multiple copies clock family members, which arose through whole genome duplication (WGD) events during evolutionary history. It remains unclear to what extent members are functionally redundant or have allowed for functional...

Small-scale subsistence farmers in South Africa have been introduced to genetically modified (GM) crops for more than a decade. Little is known about i) the extent of transgene introgression into locally recycled seed, ii) what short and long-term ecological socioeconomic impacts such mixing seeds might have, iii) how perceive GM crops, iv) degree approval conditions are followed controlled. This study conducted Eastern Cape, Africa, aims primarily at addressing first these issues. We...

The aquaculture industry is under pressure to satisfy global demand for marine foods. Atlantic salmon has been bred more than 40 years, and substantial progress made within the culturing breeding programs. improved growth rate of accompanied by an earlier onset maturation. Among factors controlling maturation in are photoperiod, temperature, body composition. Early sexual detrimental fish health quality when viewed from aquacultural viewpoint. There several approaches alleviating this...

Atlantic salmon migrate to sea following completion of a developmental process known as smolting, which establishes seawater (SW) tolerant phenotype. Smolting is stimulated by exposure long photoperiod or continuous light (LL) period short (SP), and this leads major changes in gill ion exchange osmoregulatory function. Here, we performed an RNAseq experiment discover novel genes involved photoperiod-dependent remodeling the gill. This revealed cohort whose expression rises dramatically fish...

The molecular repertoire of the mucosa-associated lymphoid tissue (MALT) in olfactory rosette most teleost fish is unknown. Here we present basal transcriptome Atlantic salmon (Salmo salar). To investigate its mucosal immune features, performed a comparative transcriptomic analysis with gills, one studied organs possessing MALT. Pathway enrichment revealed that cytokine-cytokine interaction and neuroactive ligand-receptor pathways were at core shared similarity between two organs....

Abstract We discuss a 44-month longitudinal study of the stability two-factor Norwegian Book Suggestibility Scale for Children (BSSC; Melinder, Scullin, Gunner⊘d, & Nyborg, 2005) in sample 7-year-old children (M Time 2 age=94 months). Several measures suggestibility were assessed: yielding to suggestive questions (Yield), shifting answers response negative feedback (Shift), sum Yield and Shift (Total Suggestibility), open-ended misleading direct tag about an event experienced 44 months...

Abstract The developmental transition of juvenile salmon from a freshwater resident morph (parr) to seawater (SW) migratory (smolt), known as smoltification, entails reorganization gill function cope with the altered water environment. Recently, we used RNAseq characterize breadth transcriptional change which takes place in FW phase smoltification. This highlighted importance extended exposure short, winter-like photoperiods (SP) followed by subsequent increase photoperiod for completion...

We report the histological and transcriptomic changes in olfactory organ of Atlantic cod exposed to Francisella noatunensis. Experimental infection was performed at either 12 °C or 17 °C. Infected fish presented classic gross pathologies francisellosis. Nasal morpho-phenotypic parameters were not significantly affected by elevated temperature infection, except for number mucus cells group seven weeks after challenge. A higher genes altered through time reared At termination, nasal...

For production wells in depleted reservoirs, identifying the oil and gas zones for completion is a long-lasting challenge. This not because conventional logging-while-drilling tools are working but due to increased complexity of reservoir fluids under conditions. In this scenario, no longer single-phase two-phase conditions released from or displacement aquifer movement during production. There strong business need an accurate fluid-typing solution without additional data acquisition. We use...

Abstract The developmental transition of juvenile salmon from a freshwater resident morph (parr) to seawater (SW) migratory (smolt) requires range physiological adaptations, including the capacity hypo-osmoregulate. This process, known as smolting, involves both photoperiod-dependent preparative changes before SW is encountered, and activational stimulated by exposure SW. To explore relationship between these two aspects we undertook experiments in which transcriptomic responses SW-challenge...

Abstract Anadromous salmonids begin life adapted to the freshwater environments of their natal streams before a developmental transition, known as smoltification, transforms them into marine-adapted fish. In wild, extending photoperiods spring stimulates typified by radical reprogramming gill from an ion-absorbing organ ion-excreting organ. Prior work has highlighted role specialized “mitochondrion-rich” cells in delivering this phenotype. However, transcriptomic studies identify thousands...
