Territorial choruses of giant otter groups (Pteronura brasiliensis) encode information on group identity

Group living animals often engage in corporate territorial defence. Territorial group vocalizations can provide information about group identity, size and composition. Neighbouring groups may use this information to avoid unfavourable direct conflicts. Giant otters are highly social and territorial ...

Usability Test of Exercise Games Designed for Rehabilitation of Elderly Patients After Hip Replacement Surgery: Pilot Study

Background Patients who receive rehabilitation after hip replacement surgery are shown to have increased muscle strength and better functional performance. However, traditional physiotherapy is often tedious and leads to poor adherence. Exercise games, provide ways for increasing the engagement of ...

A description of the gross pathology of drowning and other causes of mortality in seabirds

Background Mortality of seabirds due to anthropogenic causes, especially entrapment in fishing gear, is a matter of increasing international concern. This study aimed at characterising the gross pathology of seabirds that drowned in fishing nets and comparing it with that in other common causes of ...

Effects of fish movement assumptions on the design of a marine protected area to protect an overfished stock

Marine Protected Areas (MPA) are important management tools shown to protect marine organisms, restore biomass, and increase fisheries yields. While MPAs have been successful in meeting these goals for many relatively sedentary species, highly mobile organisms may get few benefits from this type of ...

Diversity and Antimicrobial Potential of Predatory Bacteria from the Peruvian Coastline

The microbiome of three different sites at the Peruvian Pacific coast was analyzed, revealing a lower bacterial biodiversity at Isla Foca than at Paracas and Manglares, with 89 bacterial genera identified, as compared to 195 and 173 genera, respectively. Only 47 of the bacterial genera identified were ...

Revealing Hidden Diversity of the Underestimated Neotropical Ichthyofauna: DNA Barcoding in the Recently Described Genus Megaleporinus (Characiformes: Anostomidae)

Molecular studies have improved our knowledge on the neotropical ichthyofauna. DNA barcoding has successfully been used in fish species identification and in detecting cryptic diversity. Megaleporinus (Anostomidae) is a recently described freshwater fish genus within which taxonomic uncertainties remain. ...

Comparative cytogenetic analysis of marine Palaemon species reveals a X1X1X2X2/X1X2Y sex chromosome system in Palaemon elegans

Background The maintenance of species and the promotion of speciation are closely related to chromosomal rearrangements throughout evolution. Decapoda represents the most species-rich order among crustaceans and, despite its ecological and economic importance, little is known about decapod karyology. ...

Reproduction of an azooxanthellate coral is unaffected by ocean acidification

Anthropogenic carbon dioxide (CO2) emissions and consequent ocean acidification (OA) are projected to have extensive consequences on marine calcifying organisms, including corals. While the effects of OA on coral calcification are well documented, the response of reproduction is still poorly understood ...

The sea cucumber genome provides insights into morphological evolution and visceral regeneration

Apart from sharing common ancestry with chordates, sea cucumbers exhibit a unique morphology and exceptional regenerative capacity. Here we present the complete genome sequence of an economically important sea cucumber, A. japonicus, generated using Illumina and PacBio platforms, to achieve an assembly ...

Three Draft Genome Sequences of Vibrio coralliilyticus Strains Isolated from Bivalve Hatcheries

ABSTRACT Reported here are the genome sequences of three Vibrio coralliilyticus isolates RE87, AIC-7, and 080116A. Each strain was isolated in association with oyster larvae in commercial aquaculture systems. These draft genomes will be useful for further studies in understanding the genomic features ...

Chloroplast Genome Sequences of Seven Strains of the Bloom-Forming Raphidophyte Heterosigma akashiwo

ABSTRACT We report here the complete chloroplast genome sequences of seven strains of the bloom-forming raphidophyte Heterosigma akashiwo. These ~160-kb sequences contain 124 protein-, 6 rRNA-, and 34 tRNA-coding sequences. Notable sequence variations were observed among these seven sequenced and two ...

The Greenland shark Somniosus microcephalus—Hemoglobins and ligand-binding properties

A large amount of data is currently available on the adaptive mechanisms of polar bony fish hemoglobins, but structural information on those of cartilaginous species is scarce. This study presents the first characterisation of the hemoglobin system of one of the longest-living vertebrate species (392 ...

Hydraulic steering system for vehicles, particularly for watercrafts or the like

Hydraulic steering system for means of transport, particularly for watercrafts or the like, comprising: at least one steering control member (1) such as a steering wheel, a rudder tiller or helm; a hydraulic pump (2) provided with a rotatable driving shaft (102) and on which said control member (1) ...

Spherical rescue unit

A spherical rescue unit (100) comprising a gyro stabilized rescue capsule (103), said capsule is placed inside a set of guide rails (109) and attached to said set of guide rails (109) via bearing, said set of guide rails (109) is attached to a floating arrangement further characterized in the floating ...

Epidemiological link of a major cholera outbreak in Greater Accra region of Ghana, 2014

Background Cholera remains an important public health challenge globally. Several pandemics have occurred in different parts of the world and have been epidemiologically linked by different researchers to illustrate how the cases were spread and how they were related to index cases. Even though the ...

Antioxidant humic acid derivatives and methods of preparation and use

Disclosed are antioxidative, natural compounds, their salts, chelates and cleavage derivatives that exhibit a superior combination of properties. The compounds can be used for a variety of purposes, including stabilizing foods, cosmetics, beverages and nutritional supplement. The compounds can be prepared ...

Ursolic Acid, a Natural Nutraceutical Agent, Targets Caspase3 and Alleviates Inflammation‐Associated Downstream Signal Transduction

Scope Ursolic acid (UA) is a pentacyclicterpenoid carboxylic acid that is present in a wide variety of plant foods. There are many beneficial health effects that are attributed to the properties of UA. However, the specific cellular targets of UA and the mechanism underlying downstream signal transduction ...

The effects of familiarity on escape responses in the Trinidadian guppy (Poecilia reticulata)

Predation is the main cause of mortality during early life stages. The ability to avoid and evade potential threats is, therefore, favoured to evolve during the early stages of life. It is also during these early stages that the process of familiarization occurs. It has long been recognized that associating ...

Correction: Soy and fish as features of the Japanese diet and cardiovascular disease risks

The ability of algal organic matter and surface runoff to promote the abundance of pathogenic and non-pathogenic strains of Vibrio parahaemolyticus in Long Island Sound, ...

Food safety is a major concern in the shellfish industry, as severe illness can result from consuming shellfish that have accumulated waterborne pathogens. Shellfish harvesting areas are typically monitored for indicator bacteria such as fecal coliforms that serve as proxies for enteric pathogens although ...
