Phenotypic plasticity in specialists: How long-spined larval Sympetrum depressiusculum (Odonata: Libellulidae) responds to combined predator cues

Phenotypic plasticity is a common defensive strategy in species experiencing variable predation risk, such as habitat generalists. Larvae of generalist dragonflies can elongate their abdominal spines in environments with fish, but long spines render larvae susceptible to invertebrate predators. Long-spined ...

Decadal erosion of coral assemblages by multiple disturbances in the Palm Islands, central Great Barrier Reef

Increases in the frequency of perturbations that drive coral community structure, such as severe thermal anomalies and high intensity storms, highlight the need to understand how coral communities recover following multiple disturbances. We describe the dynamics of cover and assemblage composition of ...

Interphase human chromosome exhibits out of equilibrium glassy dynamics

Fingerprints of the three-dimensional organization of genomes have emerged using advances in Hi-C and imaging techniques. However, genome dynamics is poorly understood. Here, we create the chromosome copolymer model (CCM) by representing chromosomes as a copolymer with two epigenetic loci types corresponding ...

Water, water everywhere: environmental DNA can unlock population structure in elusive marine species

Determining management units for natural populations is critical for effective conservation and management. However, collecting the requisite tissue samples for population genetic analyses remains the primary limiting factor for a number of marine species. The harbour porpoise (Phocoena phocoena), one ...

Killer whale (Orcinus orca) interactions with blue-eye trevalla (Hyperoglyphe antarctica) longline fisheries

Over the past five decades, marine mammal interactions with fisheries have become a major human-wildlife conflict globally. The emergence of longline fishing is concomitant with the development of depredation-type interactions i.e., marine mammals feeding on fish caught on hooks. The killer whale (Orcinus ...

Exploring the Impact of the Biofloc Rearing System and an Oral WSSV Challenge on the Intestinal Bacteriome of Litopenaeus vannamei

We provide a global overview of the intestinal bacteriome of Litopenaeus vannamei in two rearing systems and after an oral challenge by the White spot syndrome virus (WSSV). By using a high-throughput 16S rRNA gene sequencing technology, we identified and compared the composition and abundance of bacterial ...

The contribution of nano-zinc to alleviate salinity stress on cotton plants

To investigate the effect of nano-zinc fertilizer on growth, yield and mineral status of cotton plants grown under salt stress, a pot experiment was set up in the greenhouse of the National Research Centre. The treatments were as follows: (I) diluted seawater: 10% (S1), 20% (S2) and tap water as a control ...

A Comparative Evaluation of Carcass Quality, Nutritional Value, and Consumer Preference of Oreochromis niloticus from Two Impoundments with Different Pollution Levels in ...

The objective of the study was to determine the quality and consumer preferences of Nile tilapia (Oreochromis niloticus) from two water bodies with different pollution levels and trophic states. Water quality assessment of the two impoundments was carried out. Fish were sampled from hypereutrophic Lake ...

Characterization of Extended-Spectrum β-Lactamase-Producing Enterobacteriaceae From Retail Food in China

In this study, we characterized the β-lactamase genes and phenotypic resistance of cephalosporin-resistant Enterobacteriaceae isolated from retail foods in China. Of 1,024 Enterobacteriaceae isolates recovered from raw meat products, aquatic products, raw vegetables, retail-level ready-to-eat (RTE) ...

Mesopredatory fishes from the subtropical upwelling region off NW-Africa characterised by their parasite fauna

Eastern boundary upwelling provides the conditions for high marine productivity in the Canary Current System off NW-Africa. Despite its considerable importance to fisheries, knowledge on this marine ecosystem is only limited. Here, parasites were used as indicators to gain insight into the host ecology ...

Herbivore biocontrol and manual removal successfully reduce invasive macroalgae on coral reefs

Invasive macroalgae pose a serious threat to coral reef biodiversity by monopolizing reef habitats, competing with native species, and directly overgrowing, and smothering reef corals. Several invasive macroalgae (Eucheuma clade E, Kappaphycus clade A and B, Gracilaria salicornia, and Acanthophora spicifera) ...

Effects of dietary aflatoxin B1 on accumulation and performance in matrinxã fish (Brycon cephalus)

Aflatoxins (AF) can be cumulative in fish tissues and can influence weight, length, feed intake and survival depending on the species. The aim of this work is to measure performance and aflatoxin levels in tissues of matrinxã (Brycon cephalus) fish chronically exposed to aflatoxin. Aflatoxin was incorporated ...

Testing the utility of DNA barcodes and a preliminary phylogenetic framework for Chinese freshwater mussels (Bivalvia: Unionidae) from the middle and lower Yangtze River

The middle and lower portions of the Yangtze River basin is the most species-rich region for freshwater mussels in Asia. The management and conservation of the taxa in this region has been greatly hampered by the lack of a well-developed phylogeny and species-level taxonomic framework. In this study, ...

Food safety impacts of antimicrobial use and their residues in aquaculture

Background Residues of antimicrobials in food have received much attention in recent years because of growing food safety and public health concerns. Their presence in food of animal origin constitutes socioeconomic challenges in international trade in animal and animal products. The major public health ...

Food compositions having a realistic meat-like appearance, feel and texture

The invention provides novel food compositions having a realistic meat-like appearance, feel, and texture. The compositions comprise from about 40 to about 90% functional proteins, from about 0.05 to about 2% of one or more cross-linking agents, and from about 60 to about 10% of a meat slurry, wherein ...

Peptides from fish gelatine

The invention relates to a process of preparing low molecular weight peptides from gelatine. The gelatine is broken down into low molecular weight peptides using enzymes from Bacillus sp. to obtain peptides with low ash content. The gelatine is clarified by adjusting the pH to 7 using alkali hydroxide ...

Method and device for cryogenic freezing of products using a porous conveyor carrier and for minimizing cryogenic consumption

A device for the total or partial freezing of articles, comprising a conveyor made of a porous material isolated by an enclosure, as well as means for impregnating a cryogenic liquid of said conveyor, and means for disposing of the articles to be frozen on the porous conveyor, characterized by the following ...

When context modulates the influence of action observation on language processing

Numerous studies in the field of embodied cognition have shown a crosstalk between language and sensorimotor processes. In particular, it has been demonstrated that perceiving an action influences subsequent language processing. However, when studying the effect of action observation on language processing ...

Apparatus for predicting a power consumption of a maritime vessel

The invention relates to an apparatus 100 for predicting a power consumption of a maritime vessel. The apparatus 100 comprises an input interface 101 configured to receive a speed of the maritime vessel and a physical parameter of a maritime environment of the maritime vessel, the speed and the physical ...

System providing multiple services using sensors with central control unit for vessels

A multiple services system through sensors having a central monitoring unit for vessels, consisting of a central monitoring unit (2) and a set of sensors (3) being connected to each other in a wireless way, and being susceptible to establish communication through the central monitoring unit (2) with ...
