Fatty acids (FA) are a major source of nutrients and energy in aquatic food webs, as well serving the main components all cell membranes. Increasing anthropogenic impacts (e.g., climate change) predicted to selectively alter production these critical compounds, with potential cascading effects reaching higher trophic level organisms, including humans. To provide more comprehensive assessment effects, we synthesized systematically explored differences abundance distribution FA fish, due their...
Lipids are key compounds in marine ecosystems being involved organism growth, reproduction, and survival. Despite their biological significance ease of measurement, the use lipids deep-sea studies is limited, as our understanding energy nutrient flows deep ocean. Here, a comprehensive analysis total lipid content, class fatty acid composition, was used to explore functional diversity nutritional content within faunal assemblage comprising 139 species from 8 phyla, including Chordata,...
Synthetic and non-synthetic microfibers are found in habitats wildlife globally. Yet, it remains unclear whether different microfiber types affect fish or increase bioaccumulation of sorbed persistent organic pollutants (POPs). To better understand effects fish, we tested (cotton polyester), to examine as a vector chemicals them with without chemical mixtures (clean exposed treated wastewater effluent). The on survival, growth, condition indices, fatty acids, along polybrominated diphenyl...
Abstract Anguillid eels were once considered to be the classic example of catadromy. However, alternative life cycles have been reported, including skipping freshwater phase and habitat shifting between fresh, brackish, saltwater throughout growth phase. There is a lack knowledge regarding these alternate strategies, for example, proportion individuals in population that adopt them compared We provide description cycle strategies temperate anguillids, their possible drivers, methods...
We combined fatty acid (FA) and stable isotope (SI) analyses to investigate the trophic ecology of different stages European eels (Anguilla anguilla) across seawater (SW), brackish water (BW), freshwater (FW) habitats. Salinity was main driver differences in biochemical composition, greatest variation occurred between SW FW eels. had a higher content FA indicator carnivory, as well highest ratios (C, N). In contrast, exhibited lipid omega-6 polyunsaturated FA, but lowest ratios, suggesting...
Many anguillid eel species display facultative catadromy. Some spend their entire life cycle in marine coastal areas, but the geographical extent of this, especially at extremes distributional ranges, is unknown. We analysed otolith Sr:Ca and Ba:Ca from yellow-stage European ( Anguilla anguilla) sampled along coast Norway several freshwater lakes (58°N–63°N), to infer initial settlement later movement patterns with regards habitat salinity. Most (80%) habitats n = 371) had settled remained...
Natural variations in the 13C:12C ratio (carbon-13 isotopic abundance [δ13C]) of food supply have been used to determine dietary origin and metabolism fatty acids, especially n-3 polyunsaturated acid (PUFA) biosynthesis pathway. However, n-6 PUFA following linoleic (LNA) intake remains under investigated. Here, we sought use natural δ13C signature oils fish analyze changes LNA eicosapentaenoic (EPA) + docosahexaenoic (DHA) adult humans. Participants with migraine (aged 38.6 ± 2.3 y, 93%...
Abstract Fatty acids in neutral and polar lipids were used to investigate trophic connections species from five families of demersal (Rajella fyllae, Malacoraja senta, Alepocephalus bairdii, Borostomias antarcticus) pelagic fish (Bathytroctes macrolepis, Lampanyctus spp., Chaulidos sloani, Serrivomer beanii) sampled the deep Atlantic Ocean off Newfoundland, Canada. Lipid extracts fractionated into neutral, acetone-mobile polar, phospholipids separate fatty storage those membranes....
Abstract. Biochemical markers developed initially for food-web studies of terrestrial and shallow-water environments have only recently been applied to deep-sea ecosystems (i.e., in the early 2000s). For first time since their implementation, this review took a close look at existing literature field trophic ecology synthesize current knowledge. Furthermore, it provided an opportunity preliminary analysis global geographic latitudinal, along depth gradient) trends isotopic (δ15N, δ13C) fatty...
Lipids, particularly fatty acids (FAs), are major sources of energy and nutrients in aquatic ecosystems play key roles during vertebrate development. The European eel Anguilla anguilla goes through biochemical physiological changes throughout its lifecycle as it inhabits sea- (SW), and/or brackish- (BW) freshwater (FW) habitats. With the ultimate goal being to understand reasons for eels adopting a certain life history strategy (FW or SW residency vs. 'habitat shifting'), we explored...
Triterpenoid biosynthesis is generally anaerobic in bacteria and aerobic Eukarya. The major class of triterpenoids bacteria, the hopanoids, different to that Eukarya, lanostanoids, their 4,4,14-demethylated derivatives, sterols. In deep sea, prokaryotic contribution primary productivity has been suggested be higher because local environmental conditions prevent classic photosynthetic processes from occurring. Sterols have used as trophic biomarkers producers compositions, they are...
Abstract The European eel is a facultative catadromous species, meaning that it can skip the freshwater phase or move between marine and habitats during its continental life stage. Otolith microchemistry, used to determine habitat use of salinity history, requires sacrifice animals. In this context, blood-based gene expression may represent non-lethal alternative. work, we tested ability blood transcriptional profiling identify different salinity-habitat histories eel. Eels collected from...
