Bioluminescent flashes drive nighttime schooling behavior and synchronized swimming dynamics in flashlight fish

Schooling fishes, like flocking birds and swarming insects, display remarkable behavioral coordination. While over 25% of fish species exhibit schooling behavior, nighttime schooling has rarely been observed or reported. This is due to vision being the primary modality for schooling, which is corroborated ...

Using REACH for the EU Environmental Footprint: Building a Usable Ecotoxicity Database, Part I

ABSTRACT The European Union Environmental Footprint (EU‐EF) is a harmonized method to measure and communicate the life cycle environmental performance of products and organizations. Among 16 different impact categories included in the EU‐EF, 1 focuses on the impact of substances on freshwater ecosystems ...

Comparing Options for Deriving Chemical Ecotoxicity Hazard Values for the European Union Environmental Footprint, Part II

ABSTRACT Using the European Union's Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) ecotoxicity data, this paper compares 3 different approaches to calculate final substance toxicity hazard values using the USEtox approach (chronic EC50 + acute EC50/2), using only acute ...

Extraction of essential oils

Essential oils are extracted from a biomass through milling in a solvent to form a solution of the essential oil in the solvent. The solvent is or is part of a cover than reduces oxidative and other degradation of the essential oil during milling and isolation. The solubilized essential oil may be allowed ...

Methods for making grill-type smoked food ingredients

A method for making a liquid (e.g. water or oil)-based food ingredient, having grill flavour properties, comprises: combusting in the presence of oxygen, an intimate mixture of (i) 2 - 15 parts by weight smoke source and (ii) 1 part by weight flavour source, to generate smoke; and combining the smoke ...

Method for making grill-type smoked food ingredients

A method for making an oil-based food ingredient, having grill flavour properties, comprises: combusting at a temperature of from 200 to 380 degrees C, in the presence of oxygen, a mixture of (i) 2 - 15 parts by weight smoke source and (ii) 1 part by weight flavour source, to generate smoke; and combining ...

Alcoholic beverage containing particles comprising a caviar-based foodstuff

The present invention relates to particles which comprise at least one gelled network of at least one gelling polysaccharide in which are embedded at least: —one caviar-based food; —one agent for reinforcing the gelled network of the gelling polysaccharide and which is resistant to alcohol; and water, ...

Process for producing a foamed meat or fish product

The invention relates to a process for producing a foamed meat or fish product, comprising the steps of: delivering a pumpable starting material containing comminuted meat or fish and pieces of bone or cartilage to a dispersing apparatus having a chamber with a cylindrical rotor disposed therein, which ...

Monitoring Silane Sol-Gel Kinetics with In-Situ Optical Turbidity Scanning and Dynamic Light Scattering

Organosilanes (e.g., R’-SiOR3) provide hydrophobic functionality in thin-film coatings, porous gels, and particles. Compared with tetraalkoxysilanes (SiOR4), organosilanes exhibit distinct reaction kinetics and assembly mechanisms arising from steric and electronic properties of the R’ group on the ...

The effect of mangrove restoration on avian assemblages of a coastal lagoon in southern Mexico

Background Mangrove forests provide many ecosystem services, including the provision of habitat that supports avian biodiversity. However, hurricanes can knock down trees, alter hydrologic connectivity, and affect avian habitat. In 1995, Hurricanes Opal and Roxanne destroyed approximately 1,700 ha ...

The acute physiological status of white sharks (Carcharodon carcharias) exhibits minimal variation after capture on SMART drumlines

Abstract Drumlines incorporating SMART (Shark-Management-Alert-in-Real-Time) technology are a new tool used in several bather protection programmes globally. In New South Wales (NSW), Australia, the white shark (Carcharodon carcharias) is a target species for SMART drumlines because they are often ...

Applying science to pressing conservation needs for penguins

Abstract More than half of the world's 18 penguin species are declining. We, the Steering Committee of the International Union for Conservation of Nature Species Survival Commission Penguin Specialist Group, determined that the penguin species in most critical need of conservation action are African ...

Molecular Epizootiology of Toxoplasma gondii and Cryptosporidium parvum in the Eastern Oyster (Crassostrea virginica) from Maine (USA)

Shellfish are known as a potential source of Toxoplasma gondii (responsible for toxoplasmosis), and Cryptosporidium parvum, which is one of the major causes of gastroenteritis in the world. Here we performed a comprehensive qPCR-based monthly survey for T. gondii and C. parvum during 2016 and 2017 in ...

Evolution and diversity of two cisco forms in an outlet of glacial Lake Algonquin

Abstract The diversity of Laurentian Great Lakes ciscoes (Coregonus artedi, sensu lato) arose via repeated local adaptive divergence including deepwater ciscoes that are now extirpated or threatened. The nigripinnis form, or Blackfin Cisco, is extirpated from the Great Lakes and remains only in Lake ...

Fluorescence in Situ Hybridization (FISH) for Detecting Anaplastic Lymphoma Kinase (ALK) Rearrangement in Lung Cancer: Clinically Relevant Technical Aspects

In 2011, the Vysis Break Apart ALK fluorescence in situ hybridization (FISH) assay was approved by the United States Food and Drug Administration as a companion diagnostic for detecting ALK rearrangement in lung cancer patients who may benefit from treatment of tyrosine kinase inhibitor therapy. This ...

Hydrolysed Collagen from Sheepskins as a Source of Functional Peptides with Antioxidant Activity

The extraction and enzymatic hydrolysis of collagen from sheepskins at different times of hydrolysis (0, 10, 15, 20, 30 min, 1, 2, 3 and 4 h) were investigated in terms of amino acid content (hydroxyproline), isoelectric point, molecular weight (Mw) by sodium dodecyl sulphate polyacrylamide gel electrophoresis ...

Preoptic Area Activation and Vasotocin Involvement in the Reproductive Behavior of a Weakly Pulse-Type Electric Fish, Brachyhypopomus gauderio

Social behavior exhibits a wide diversity among vertebrates though it is controlled by a conserved neural network, the social behavior network (SBN). The activity of the SBN is shaped by hypothalamic nonapeptides of the vasopressin-oxytocin family. The weakly electric fish Brachyhypopomus gauderio emits ...

Dynamic Expression and Regulation of Urotensin I and Corticotropin-Releasing Hormone Receptors in Ovary of Olive Flounder Paralichthys olivaceus

Urotensin I (UI), a fish corticotropin-releasing hormone (CRH) like peptide, has been found throughout vertebrate species that has great effects on adaptive physiology comprising stress-related responses, and osmotic regulation by binding with CRH type I receptor (CRHR1) and CRH type II receptor (CRHR2) ...

Physiological Responses of Pacific White Shrimp Litopenaeus vannamei to Temperature Fluctuation in Low-Salinity Water

Temperature is a significant environmental factor in aquaculture. To investigate the physiological responses during temperature fluctuation (28~13°C), experimental shrimps (Litopenaeus vannamei) were treated with gradual cooling from acclimation temperature (AT, 28°C) to 13°C with a cooling rate of ...

Genetic and Biochemical Evidence That Enterococcus faecalis Gr17 Produces a Novel and Sec-Dependent Bacteriocin, Enterocin Gr17

Bacteriocins are ribosomally synthesized antibacterial peptides or proteins from microorganisms. We report a novel bacteriocin producing strain, Enterococcus faecalis Gr17, that was isolated from the Chinese traditional low-salt fermented whole fish product Suan yu. E. faecalis Gr17 displayed potent ...
