Paired spawning with male rotation of meagre Argyrosomus regius using GnRHa injections, as a method for producing multiple families for breeding selection programs
(Elsevier, 2018-06-08)
Weekly gonadotropin-releasing hormone agonist (GnRHa) injections were used to induce spawning in paired male and female meagre (Argyrosomus regius) with a weekly rotation of the males, in order to produce ...
Dependence of pH values in the digestive tract of freshwater fishes on some abiotic and biotic factors
(Springer, 2017-10-09)
The values of pH in the digestive tracts of 20 freshwater fish species inhabiting various Russian Federation waterbodies were studied. Only in six species (Coregonus lavaretus, Coregonus migratorius, ...
Occurrence of cyclic imines in European commercial seafood and consumers risk assessment
(Elsevier, 2017-12-01)
Cyclic imines constitute a quite recently discovered group of marine biotoxins that act on neural receptors and that bioaccumulate in seafood. They are grouped together due to the imino group functioning ...
Herbivore control in connected seascapes: habitat determines when population regulation occurs in the life history of a key herbivore
(Wiley, 2018-02-08)
Herbivore outbreaks often trigger catastrophic overgrazing events in marine macrophyte ecosystems. The sea urchin Paracentrotus lividus, the dominant herbivore of shallow Mediterranean seascapes, is ...
The cellular localization and redistribution of multiple aquaporin paralogs in the spermatic duct epithelium of a maturing marine teleost
(Wiley, 2018-05-27)
Aquaporin‐mediated fluid transport in the mammalian efferent duct and epididymis is believed to play a role in sperm maturation and concentration. In fish, such as the marine teleost gilthead seabream ...
Do the Escherichia coli European Union shellfish safety standards predict the presence of Arcobacter spp., a potential zoonotic pathogen?
(Elsevier, 2017-12-27)
The genus Arcobacter comprises Campylobacter-related species, considered zoonotic emergent pathogens, the presence of which in water has been associated with fecal pollution. Discharges of fecal polluted ...
Skeletogenesis in the Persian sturgeon Acipenser persicus and its correlation with gene expression of vitamin K‐dependent proteins during larval development
(Wiley, 2018-01-18)
The present study describes morphological development of the skeleton in the Persian sturgeon Acipenser persicus and discusses the hypothesis that expression of genes encoding vitamin K‐dependent proteins ...
Update on Mycoplasma hyopneumoniaeinfections in pigs: Knowledge gaps for improved disease control
(Wiley, 2017-08-23)
Mycoplasma hyopneumoniae(M. hyopneumoniae) is the primary pathogen of enzooticpneumonia, a chronic respiratory disease in pigs. Infections occur worldwide andcause major economic losses to the pig ...
The role of forest maturity in extreme hydrological events
(Wiley, 2018-02-10)
This study aims to clarify the influence of forests, as well as other prevalent land cover types, on extreme hydrological events through a land cover gradient design. We selected 10 catchments within a ...
Avoiding quantification bias in metabarcoding: Application of a cell biovolume correction factor in diatom molecular biomonitoring
(Wiley, 2017-12-26)
In recent years, remarkable progress has been made in developing environmental DNA metabarcoding. However, its ability to quantify species relative abundance remains uncertain, limiting its application ...
