Understanding species linkages and energy transfer is a basic goal underlying any attempt at ecosystem analysis. Although the first food-web studies were based on gut contents of captured specimens, the assessment of stable isotopes, mainly δ13C and δ15N, has become a standard methodology for wide-range analyses in the last 30 years. Stable isotopes provide information on the trophic level of s...

In the North-Western Mediterranean Sea (NWMS), changes in size and taxonomic composition of zooplankton have been hypothesized to underlie observed populations Sardina pilchardus, one main small pelagic fish species. The present study was undertaken better understand link between temporal variability diet adult sardine Bay Marseille over a period 16 months by comparing prey stomach content with...

Abstract Background The present study assessed the growth and mortality parameters of white sardine, Escualosa thoracata which is having high local demand. sardine gained importance due to its taste, demand in domestic markets as compared oil necessitated a on this resource know status exploitation level along central west coast India. Results A total 3026 individuals different size groups E. w...

Abstract Sustainable fishing practices must ensure human wellbeing by safeguarding the integrity of marine life-supporting systems. Unfortunately, a significant challenge to fisheries management is that sustainable levels can decline, often synergistically, co-occurring with climate-driven environmental stressors. Within one most impacted areas in world, and encompassing number highly targeted ...

Viral haemorrhagic septicaemia virus (VHSV) is a fish pathogen found throughout the Northern Hemisphere and is capable of infecting and causing mortality in numerous marine and freshwater hosts. In the coastal waters of British Columbia, Canada, the virus has been detected for 20 yr with many occurrences of mass mortalities among populations of Pacific herring Clupea pallasii (Valenciennes) and...

Fish protein hydrolysates (FPH), produced from the six main discard species from the West Mediterranean Sea (sardine, horse mackerel, axillary seabream, bogue, small-spotted catshark and blue whiting) were tested for their bile acid binding capacity. This capacity is directly linked to the ability to inhibit bile reabsorption in the ileum and therefore to lower cholesterol levels in the bloodst...

Many types of animals exhibit aggregative behavior: birds flock, bees swarm, fish shoal, and ungulates herd. Terrestrial and aerial aggregations can be observed directly, and photographic techniques have provided insights into the behaviors of animals in these environments and data against which behavioral theory can be tested. Underwater, however, limited visibility can hamper direct observati...

Arena is a software package intended to help e-commerce strategy researchers and designers test buying and selling strategies under different scenarios. It implements and adheres to a set of design criteria intended to ensure its simulation ability as well as prolonging its usable lifetime. The process of implementing Arena involved conducting background research into current strategies and the...

Vignolini et al. (1) reported the discovery of a multilayer structural reflector in the fruit of the herbaceous perennial Pollia condensata. The structural mechanism is remarkable, with a combination of different cells reflecting left-handed or righthanded circularly polarized light. However, several other significant contributions to the field of structural color deserve to be highlighted alon...
