By measuring the fluorescence spectra of pearls from various species of mother oysters, a distinction has already become possible as to whether the pearls are from Pinctada fucata, Pinctada maxima, Pteria penguin or Pinctada margaritifera. In this study, the fluorescence of pearls from freshwater bivalves was measured. The results have made it possible to distinguish freshwater pearls from the ...

Sir, The ingestion of crustacea and mollusca is one of the most frequent causes of food allergy (1). The mollusca phylum includes lamellibranchia (bivalves) and involves the following orders: mytiloida (familia mytilidae: mussels); ostreoida (familia ostreidae: oysters) and veneroida (familia veneridae: clams) (2). Herein we report a study of 11 cases of IgE-mediated urticaria/angioedema caused...

The existence of seagrass in coastal areas can affect marine biota that live around it. Seagrass has an important role as area ​​care, spawning, and protection. This study aims to determine the success conserving beds Enhalus acorodies species terms bivalve diversity on south coast East Lombok. research was conducted using transect observation methods. data obtained were analyzed evenness index...

We present the first DNA taxonomy publication on abyssal Mollusca from the Clarion-Clipperton Zone (CCZ), central Pacific ocean, using material collected as part of the Abyssal Baseline (ABYSSLINE) environmental survey cruise 'AB01' to the UK Seabed Resources Ltd (UKSRL) polymetallic-nodule exploration area 'UK-1' in the eastern CCZ. This is the third paper in a series to provide regional taxon...

A sedimentological survey of the southwest arm of the Holocene Pigeon Creek tidal lagoon on San Salvador Island, Bahamas was conducted to determine the origin and distribution of calcareous sediments. Transect surveys, surface samples, and sediment cores were collected and examined to determine the abundance and distribution of sediments and sediment producers in the lagoon and associated tidal...

Midori River estuary faces Ariake Bay,and has the largest sandy tidal flat(approximately2,100ha)in Japan.We investigated the spatial distribution of particle size composition of the sediment,microphytobenthos on the surface sediment and macrobenthic animals at the stations set along a cross transect line in Midori River estuary. The Chl-a concentrations of the surface sediment that reflected th...

Abstract The Jurassic rocks of Gebel Maghara, northern Sinai, Egypt, contain a well-preserved and highly diverse macrobenthic fauna, dominated by bivalves. This particularly bivalves gastropods, have received little attention in the last 100 years. In an attempt to provide sound database on marine bivalve diversity Egypt during period, first faunal group, protobranch bivalves, is reviewed detai...
