The climate variability hypothesis proposes that in variable temperate climates poikilothermic animals have wide thermal tolerance windows, whereas in constant tropical climates they have small thermal tolerance windows. In this study we quantified and compared the upper and lower lethal thermal tolerance limits of numerous bivalve species from a tropical (Roebuck Bay, north western Australia) ...

Introduction Conclusions References

Potassium transport characteristics were investigated in three species of freshwater bivalves: a corbiculid, Corbiculafluminea, and two unionids, Carunculina texasensis and Ligumia subrostrata. Using K, all three were found to take up potassium from dilute artificial pondwater ([K] about O.OSmmolP). The influx (7i) was 0.72/iequivg"drytissueh^ in the corbiculid, significantly higher than the va...

Specimens of four species Bivalvia not previously recorded from Iraq were discovered. These are Didimacar tenebrica, Aspidopholas obtecta, Neotrapezium sublaevigatum, and Barbatia trapezina which belong to the Noetiidae, Pholadidae, Trapezidae Arcidae families, respectively. All specimens collected alive intertidal zone northwest Persian-Arabian Gulf, Iraq, in Fao region. Although these widespr...

Bivalves are the focus of experimental research as they can filtrate a broad size range microplastics (MPs) with negative consequences for their physiology. Studies use MP shapes, materials, sizes and concentrations raising question on whether these reflect environmental observations. We review studies effects MPs marine bivalves contrast characteristics used corresponding data from environment...

Sixteen species belonging to 9 families of gastropods and bivalves have been recorded from Huneish island, Yemen. Measurments, diagnosis coloured photos for every specimen were provided .
