Branchial chamber structure and osmoregulatory function in the prawn, Palaemon elegans (Crustacea: Decapoda) from the Caspian Sea
The structure, ultrastructure and osmoregulatory function of the branchial chamber were investigated in Palaemon elegans (Rathke, 1837) by light microscope, electron microscope and immunohistochemistry methods, respectively. Each chamber possesses a branchiostegite, 3 epipodites and 8 phyllobranchiate gills. The lamellae are attached along the two outer surfaces of the triangular gill axis. Ult...

متن کاملReproduction and growth of the freshwater prawn, Palaemon paucidens (Decapoda: Palaemonidae) in a lake of Korea.
This study analyzed the reproduction and growth of freshwater prawn, Palaemon paucidens De Haan 1844 from Suk-dang lake(Korea). The analysis of the sex ratio showed a higher proportion of males than that of females. The average size of the eggs was 6.12 (+/-0.55) mm3 in the non-eyed stage (stageA) and 7.20 (+/-0.86)mm3 in the eyed stage (stage B). The reproductive output (RO) calculated with th...

15 صفحه اولSex and the Syndrome: Individual and Population Consistency in Behaviour in Rock Pool Prawn Palaemon elegans
Animal personality has been widely documented across a range of species. The concept of personality is composed of individual behavioural consistency across time and between situations, and also behavioural trait correlations known as behavioural syndromes. Whilst many studies have now investigated the stability of individual personality traits, few have analysed the stability over time of enti...
