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 ...

<i>Aim</i> - The Atlanto‐Mediterranean edible purple sea urchin, <i>Paracentrotus lividus</i>, is a commercially exploited keystone species in benthic communities. Its browsing activity can deeply modify the littoral landscape, and changes in its abundance are of major conservation concern. This species is facing nowadays contrasting anthropogenic pressures linked to predator release, exploitation ...

Any ecosystem based fisheries management system is necessarily faced with the problem of multiple objectives that trade-off against one another. Typically, objectives such as the maximization of yield, employment or profit or minimizing environmental impacts will be optimized in different parts of the decision space, which is formed of the fishing mortality rates that can be applied to the various ...

The conditions that lead to antitumor or protumor functions of natural killer T (NKT) cells against mammalian tumors are only partially understood. Therefore, insights into the evolutionary conservation of NKT and their analogs—innate-like T (iT) cells—may reveal factors that contribute to tumor eradication. As such, we investigated the amphibian <i>Xenopus laevis</i> iT cells and interacting MHC ...
