The promotion of tourism has been considered to be a key strategy in reducing people's dependence on marine resources and for creating alternative livelihoods for the communities living in Marine Protected Areas (MPAs). This paper studies the determinants for the decision of participation in tourism-related activities and examines whether tourism could be regarded as an alternative livelihood for ...

Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 marine mammals. As a group, they directly connect to the most central species (i.e cod and haddock) in the Barents Sea (i.e. cod and haddock) and consume over half of the available ...

Acute and chronic exposure to organophosphates (OPs), including agricultural pesticides, industrial chemicals, and chemical warfare agents, remain a significant worldwide health risk. The mechanisms by which OPs alter development and cognition in exposed individuals remain poorly understood, in part due to the large number of structurally diverse OPs and the wide range of affected proteins and ...

During a research cruise in 2016, we isolated fungi from sediments, seawater, driftwood, fruiting bodies, and macroalgae using three different media to assess species richness and potential bioactivity of cultivable marine fungi in the High Arctic region. Ten stations from the Svalbard archipelago (73–80 °N, 18–31 °E) were investigated and 33 fungal isolates were obtained. These grouped into 22 ...

A 12-week feeding trial was carried out to investigate possible effects of dietary orange peels derived pectin (OPDP) and <i>Lactobacillus plantarum</i> CR1T5 (LP) singularly or combined on innate immune response, disease resistance, and growth performance of Nile tilapia fingerlings under indoor biofloc system. The fingerlings were fed the following diets: diet 1 (0 g kg⁻¹ OPDP and ...

In contrast to the plethora of studies focusing on the genomic basis of adaptive phenotypic divergence, the role of gene expression during speciation has been much less investigated and consequently less understood. Yet, the convergence of differential gene expression patterns between closely related species‐pairs might reflect the role of natural selection during the process of ecological speciation. ...

Tourism development is considered a key accompanying strategy in creating alternative livelihood options for the communities living in and adjacent to the Marine Protected Areas. This paper examines the socioeconomic characteristics of the Nha Trang Bay protected area to determine the factors that influence the decision to participate in tourism sectors, and analyse whether these decisions would ...

Freshwater macroinvertebrates and fishes are focal groups in major ecosystem biomonitoring programs in the Iberian Peninsula. Yet, their use as bioindicators is sometimes constrained by the time and cost needed for sorting macroinvertebrates specimens and their challenging taxonomic identification, and the huge sampling procedures for capturing rare or incipient fish species, respectively. Given the ...

In this work, we demonstrate that the indole-oxazole-pyrrole framework of the breitfussin family of natural products is a promising scaffold for kinase inhibition. Six new halogenated natural products, breitfussin C–H (3 – 8) were isolated and characterized from the Arctic, marine hydrozoan Thuiaria breitfussi. The structures of two of the new natural products were also confirmed by total synthesis. ...

Grass carp (<i>Ctenopharyngodon idellus; n</i> = 320) were received four different diets for 56 days. The experimental diets were: fishmeal (FM) containing 10% fishmeal (without rapeseed meal), and rapeseed meal (RM) containing 50% rapeseed meal (without fishmeal), and two semi-purified diets either without (T0) or with 1.25% (T1) supplemental hydrolysable tannin. The approximate content of tannin ...
