The statistical analysis of multi-environment trial data aims to provide reliable and accurate predictions of genotype performance across the target environments and information on specific performance from the interaction of genotypes with the envir

The skins of crocodylids and gavialids can be distinguished from those of alligatorids by the presence of darkly pigmented pits, known as integumentary sense organs (ISOs), on the postcranial scales. The structure of ISOs, in Crocodylus porosus, was

Pekin ducks (Anas platyrhynchos) were bilaterally adrenalectomized (ADX) using a two-stage procedure and given daily i.m. injections of 1 mg kg bw(-1) of dexamethasone (DEXA), a steroid lacking mineralocorticoid activity, and 0.9% saline drinking wat

Dorsal aortic blood flow (DABF) and caudal venous blood flow (CVBF) were measured in free-swimming conscious freshwater (FW) North American eels (Anguilla rostrata) with Doppler-flow probes. DABF and CVBF increased in a dose-dependent manner followin

An intravenous injection of 2 μg of [Asp1,Val5]-ANG II attenuated fluid secretion by the nasal salt glands of Pekin ducks. Ganglionic blockade with mecamylamine stopped salt gland secretion. Flow was reestablished by intravenous methacholine bromide

Hypercalcemia, hypomagnesia and hypophosphatemia were observed in freshwater (FW) eels (Anguilla rostrata LeSueur) after removal of the corpuscles of Stannius. These changes did not occur if Stanniectomized (CSX) eels were removed from FW and placed

The distribution of stanniocalcin immunoreactivity was examined in the corpuscles of Stannius of the white sucker (Catostomus commersoni) by using a chum salmon stanniocalcin antiserum, Western blotting, and light and electron microscopy. The white s

Crocodylids are better adapted than alligatorids, through a suite of morphological specializations, for life in hyperosmotic environments. The presence of such specializations even in freshwater crocodylids has been interpreted as evidence for a mari

Renal function was observed in freshwater North American eels (Anguilla rostrata LeSueur) 2 weeks after the removal of the corpuscles of Stannius. There was a positive linear correlation between glomerular filtration rates and urine flow rates in bot
