The Nuclear DNA Content and Genetic Diversity of Lampetra morii
We investigated the nuclear DNA content and genetic diversity of a river lamprey, the Korean lamprey Lampetra morii, which is distributed in the northeast of China. L. morii spends its whole life cycle in fresh water, and its adult size is relatively small (~160 mm long) compared with that of other lampreys. The haploid nuclear DNA content of L. morii is 1.618 pg (approximately 1.582 Gb) in ger...

متن کاملA micropuncture study of kidney function in the river lamprey Lampetra fluviatilis adapted to sea water.
Micropuncture techniques have been used to investigate kidney function in lampreys adapted to hyperosmotic media. Plasma electrolyte concentrations were maintained well below corresponding concentrations in the external environment. Urine composition was variable, but generally showed high concentrations of magnesium, sulphate and chloride ions. Lampreys in 50% sea water produced urine which wa...
متن کاملLocalization of ion-transport in the intestine of the migrating river lamprey, Lampetra fluviatilis L.
The intestine of the river lamprey, like that of teleosts, plays a major role in marine osmoregulation (Morris, 1958; Pickering & Morris, 1970). Monovalent ions from the ingested hyperosmotic environment can be transported across the intestine against a concentration gradient ultimately producing a net water flux from the gut lumen to the bloodstream. This water movement compensates for renal a...
متن کاملMeasurement of single nephron filtration rate in the kidney of the river lamprey, Lampetra fluviatilis L.
1. The reliability of [3H]inulin as a reference substance for the measurement of glomerular filtration rate (GFR) in river lampreys was investigated. 2. Simultaneously measured renal clearances of [3H]inulin and [14C]-polyethylene glycol (PEG) were not significantly different. 3. Recoveries of [3H]inulin in the urine following its injection into the proximal tubule and urinary duct averaged 83....
