H.; University of Florida; Vanderbilt University; University of Florida j_havird@hotmail.com In mammals, prostaglandins (PGs) are involved in many physiological processes such as blood clotting, inflammation and regulation of vascular tone and osmoregulation. Cyclooxygenase (COX) is […]

WEAKLEY, J.C.; CLAIBORNE, J.B.; EDWARDS, S.L.**; James Cook University; Georgia Southern University; James Cook University susan.edwards@jcu.edu.au In fishes, most acid-base imbalances in the short term are moderated by blood and tissue buffering to lessen the impact […]

Meeting Abstract 6.10  Jan. 4  Mechanisms of water balance in hummingbirds HARTMAN BAKKEN, Bradley*; SABAT, Pablo; University of Wyoming, Laramie, Wyoming, USA; Universidad de Chile, Santiago, Chile bradley@uwyo.edu Hummingbirds face a curious osmoregulatory dilemma. To meet their high mass-specific energy demands, they regularly ingest multiples of their body mass per day in water; yet, with a high […]

Meeting Abstract 6.1  Jan. 4  Comparative immunolocalization of Na+/K+-ATPase and Na+/K+/2Cl- cotransporter in osmoregulatory tissues from marine and semi-marine snakes BABONIS, L.S.**; HYNDMAN, K.H.; LILLYWHITE, H.B.; Univ. of Florida, Gainesville babonis@ufl.edu The sublingual salt gland is the primary site of salt excretion in sea snakes. Using histology and immunohistochemistry, we located two ion transporters, Na+/K+-ATPase (NKA) and […]
