Invasive planktonic crustaceans have become a prominent feature of aquatic communities worldwide, yet their effects on food webs are not well known. The Asian calanoid copepod, Pseudodiaptomus forbesi, introduced to the Columbia River Estuary approximately 15 years ago, now dominates the late-summer zooplankton community, but its use by native aquatic predators is unknown. We investigated wheth...

This study assessed horizontal and vertical distribution abundance of zooplankton community in water samples collected from 26 stations at a depth 0 to 250 m the northern Bay Bengal. A total 55 species were identified where Copepod was 72.41% Ciliophora 8.62%. Among Copepod, 48%, 40% 12% Calanoid, Cyclopoid Harpacticoid respectively. also found 2 Decapod, Rotifer, Cladocera, 1 Chaetognatha Stom...

Amino acids (AAs) are critical biochemical compounds for living organisms. Because of the limited capacity for their de novo synthesis in many animals, the nutritional value of food largely depends on its AA composition relative to the animal’s requirements. To improve present knowledge on AA variability in freshwater crustaceans, we studied the interand intraspecific variability in three contr...

During range expansion, invasive species can experience new thermal regimes. Differences between the performance of local and alter interactions, including predator-prey interactions. The Asian tiger mosquito, Aedes albopictus , is a known vector several viral diseases public health importance. It has successfully invaded many regions across globe currently threatens to invade UK where conditio...

Abstract The occurrence of scyphozoan blooms is frequently reported in coastal areas, suggesting a need to assess its impacts on trophic webs. However, many species remain understudied with regard their feeding ecology. Here, selectivity experiments were conducted learn about the possible prey preference Catostylus tagi among mesozooplankton and estimate rates. In general, C. demonstrated relat...

A new species of copepod, Colobomatus stelliferi n. sp., belonging to the cyclopoid family Philichthyidae Vogt, 1877 is proposed based on female specimens collected from the mandibular canals of three species of sciaenid teleosts: Stellifer brasiliensis (Schultz) (type-host), S. rastrifer (Jordan) and S. stellifer (Bloch), collected in Caraguatatuba Bay, State of São Paulo, Brazil. The new spec...
