Measurements of the osmotic concentration in shrimp haemolymph were adjusted with polynomial functions (Zar 1984) and the isosmotic
point was calculated in the intersection with the line of equality.
amazonicum larvae (zoeae I, II, V, IX) and/or post-larvae exposure to different salinities (fresh water, 6, 12 or 18) about the metabolism and/or intracellular isosmotic
variabilis is isosmotic
in relation to the medium, whose mean salinity is 38[per thousand].
By 2 d after feeding, the ingested blood meal is isosmotic
with the hemolymph, which is about 200 mosm/1 (Sawyer, 1986; Zebe et al.
The aim of the present study was to examine the renal function of rats after exercise training in aquatic and land environments and to determine the effects of training on volume correction after plasma isosmotic
These results are physiologically confirmed by the reported isosmotic
point for pink shrimp to an external salinity of 28.
When the trend of increasing TMAO in bony fishes with depth is extrapolated to hadal depths, the point at which the fishes would become isosmotic
(osmoconforming) with seawater is 8000-8500 m, coinciding nicely with the maximum depth of fish from database records and observational data.
The collected fluid was pooled, an isosmotic
, anti-coagulant solution (ISO-EDTA: 20 mmol [1.
Additional energy is expended on isosmotic
intracellular ion regulation under salinity stress for both osmoconformers and osmoregulators (for reviews see Schoffeniels and Gilles (1970) and Pequeux (1995)).
Although research on the subject is scant, sponges--unlike terrestrial organisms--are thought to be isosmotic
with their surroundings (e.
The salinity of the isosmotic
point has been associated with better conditions for growth of marine aquatic crustaceans as a result of the supposed physiological comfort and lower energy expenditure with osmoregulatory activity (Silva et al.
Accordingly, Kalber and Costlow (1966) found that zoeae regulate their hemolymph hyperosmotically to external salinities below 30 ppt and are isosmotic
or slightly hypoosmotie at higher salinities.
