The value of no-take marine reserves as fisheries-management tools is controversial, particularly in high-poverty areas where human populations depend heavily on fish as a source of protein. Spillover, the net export of adult fish, is one mechanism by which no-take marine reserves may have a positive ...
Plastic responses can have adaptive significance for organisms occurring in unpredictable environments, migratory species and organisms occupying novel environments. Zebrafish (Danio rerio) occur in a wide range of habitats and environments that fluctuate frequently across seasons and habitats. We expect ...
Larval zebrafish was subjected to a methodological exploration of the gastrointestinal microbiota and transcriptome. Assessed was the impact of two dietary inclusion levels of a novel protein meal (NPM) of animal origin (ragworm Nereis virens) on the gastrointestinal tract (GIT). Microbial development ...
In the last decades the growing awareness of the ecological importance of seagrass meadows has prompted increasing efforts to protect existing beds and restore degraded habitats. An in-depth knowledge of factors acting as major drivers of propagule settlement and recruitment is required in order to ...
A cut resistant glove is provided having an inner surface and an outer surface wherein the inner surface is adapted for contacting a hand of a user, and the outer surface is visible while the user is wearing the glove. The glove includes a two layer knit fabric of a plaited construction including a ...
The protective glove according to the invention is characterized in that it includes at least one resilient member (17) integral with the chain mail fabric, arranged to draw the chain mail fabric of at least one of the glove fingers (16) in the direction or substantially in the direction of the longitudinal ...
There is herein defined a fluid delivery device (3) for a visor cleaner. The fluid delivery device (3) includes a fluid reservoir (7), which contains cleaning fluid when ready for use. The fluid delivery device (3) also includes an absorbent cleaning element (13) that is arranged to take in fluid from ...
A system for efficiently circulating water in a large volume of rearing space for aquatic organisms, comprising an impervious enclosure for containing the water and aquatic organisms and a pump for pumping water from an intake duct through intake ducting to a flow diverter, which then directs a flow ...
A flexible vibration board (12), a piezoelectric element (13) fixed to at least one side of the vibration board (12), and a fixed board (14) and a weight (16) for promoting deformation of the piezoelectric element (13) caused by vibration of the vibration board (12) are provided in the body (10). When ...
Wolbachia, a widespread endosymbiont of terrestrial arthropods, can protect its host against viral and parasitic infections, a phenotype called "pathogen blocking". However, in some cases Wolbachia may have no effect or even enhance pathogen infection, depending on the host-Wolbachia-pathogen combination. ...
Zebrafish, Denio rerio, can be an alternative to other classic animal models for human infectious diseases to examine the processes of microbial infections and host–pathogen interactions in vivo because of their small body dimension but large clutch size. We established germ-free zebrafish infection ...
Abstract The Rio Nhamundá is a poorly-known clearwater river draining the southern Guiana Shield of Brazil. In this study we report the findings of a preliminary ichthyological survey, focusing on catfishes ( Siluriformes). We identify a total of 36 species (31 genera, seven families) from the Nhamundá, ...
Marine natural products are a rich source of novel and biologically active compounds. The number of identified marine natural compounds has grown 20% over the last five years from 2009 to 2013. Several challenges, including sample collection and structure elucidation, have limited the development of ...
We developed a habitat suitability index (HSI) model to evaluate the variability of suitable habitat for neon flying squid (Ommastrephes bartramii) under anomalous environments in the Northwest Pacific Ocean. Commercial fisheries data from the Chinese squid-jigging vessels on the traditional fishing ...
An indirect competitive enzyme-linked immunosorbent assay (icELISA) and an immunochromatographic strip assay using a highly specific monoclonal antibody, were developed to detect methyltestosterone (MT) residues in animal feed. The optimized icELISA had a half-inhibition concentration value of 0.26 ...
The rise of human populations and the growth of cities contribute to the depletion of natural resources, increase their cost, and create potential climatic changes. To overcome difficulties in supplying populations and reducing the resource cost, a search for alternative pharmaceutical, nanotechnology, ...
Background Parkinson’s disease (PD) is the second most common neurodegenerative disease, affecting 2% of the population aged over 65 years old. Mitochondrial defects and oxidative stress actively participate in degeneration of dopaminergic (DA) neurons in PD. Paeonolum, a main component isolated from ...
The unparalleled biodiversity of Lake Tanganyika (Africa) has fascinated biologists for over a century; its unique cichlid communities are a preferred model for evolutionary research. Although species delineation is, in most cases, relatively straightforward, higher-order classifications were shown ...
The extant Cyprinodontiformes (killifishes) with their two suborders Cyprinodontoidei and Aplocheiloidei represent a diverse and well-studied group of fishes. However, their fossil record is comparatively sparse and has so far yielded members of the Cyprinodontoidei only. Here we report on cyprinodontiform ...
This experimental microcosm study reports the influence of organic enrichments by mussel biodeposits on the metabolic activity and functional diversity of benthic prokaryotic communities. The different biodeposit enrichment regimes created, which mimicked the quantity of faeces and pseudo-faeces potentially ...
