Birds maintain higher plasma glucose concentrations (P(Glu)) than other vertebrates of similar body mass and, in most cases, appear to store comparatively very little glucose intracellularly as… Expand
The Integration of Osmoregulation and Energy Balance in Hummingbirds
Hummingbirds subsist almost entirely on a liquid diet composed of floral nectar, and, when energy demands are high, they can consume more than three times their body mass in fluid per day. At the… Expand
Glucose transporter expression in English sparrows (Passer domesticus).
Patterns of glucose transporter expression have been well-characterized in mammals. However, data for birds is currently restricted to isolated cells, domestic chickens and chicks, and ducklings.… Expand
Function of mammalian-type and reptilian-type nephrons in kidney of desert quail.
WRAUN, ELDON J., ~%LLCAM 1% J)ANTZLER. Function of mamunalian-type and reptilian-type nephrons in kidney of desert quail. Am. J. Physiol. 222(3): 617-629. I972.---Bird kidneys have mammaliantype (MT)… Expand
Structure and concentrating ability in the avian kidney.
We quantified various aspects of the morphology of the kidney in seven bird species and related these measures to urinary concentrating ability (the concentration of ureteral urine in dehydrated… Expand
A leaf lipoxygenase of potato induced specifically by pathogen infection.

Lipoxygenase (LOX) activity has been identified consistently during pathogen-induced defense responses. Here we report the involvement of a specific leaf LOX gene of potato (Solanum tuberosum),… Expand
Osmoregulation in the Field by Salt-Marsh Savannah Sparrows Passerculus sandwichensis beldingi
We studied the osmoregulatory strategy of salt-marsh savannah sparrows (Passerculus sandwichensis beldingi) in the field in Baja California, Mexico, and we compared these birds with a subspecies of… Expand
Scaling of osmotic regulation in mammals and birds.
Allometric equations provide a means of summarizing and relating the components of renal structure and function in water balance and osmotic regulation. These summary equations also serve as base… Expand
Ingress of Clavibacter michiganensis subsp. michiganensis into Tomato Leaves Through Hydathodes.
ABSTRACT Hydathodes of tomato leaves served as extremely efficient infection courts for the bacterial canker pathogen, Clavibacter michiganensis subsp. michiganensis. Chlorotic lesions developed at… Expand
Sodium chloride and water transport in the thin descending limb of Henle of the quail.

Birds and mammals can produce hyperosmotic urine, but their renal morphology and urine-concentrating mechanisms differ. To elucidate the countercurrent urine concentration mechanism in birds, we… Expand
