The burrow microhabitat of the land crab Cardisoma guanhumi: Respiratory/ionic conditions and physiological responses of crabs to hypercapnia
Pinder, Alan W., and Allan W. Smits. 1993. "The burrow microhabitat of the land crab Cardisoma guanhumi: Respiratory/ionic conditions and physiological responses of crabs to hypercapnia." Physiological zoology 66(2): 216-236.Cardisoma guanhumi in Puerto Rico spend much of the dry season in burrows that descend to groundwater. Burrows are sometimes 3-4 m deep and may be capped with dried mud for over 3 mo. Samples of gas and water from burrows ... -
Effect of Boundary Layers on Cutaneous Gas Exchange
Pinder, A. W., and M. E. Feder. 1990. "Effect of Boundary Layers on Cutaneous Gas Exchange." Journal of Experimental Biology 154: 67-80.Boundary layers may offer significant resistance to cutaneous oxygen uptake by amphibians in water. This hypothesis was tested by measuring resistance to oxygen uptake as a function of water velocity in bullfrogs submerged ... -
Effect of Coronary Ablation and Adrenergic-Stimulation on In-Vivo Cardiac-Performance in Trout (Oncorhynchus-Mykiss)
GAMPERL, AK, AW PINDER, and RG BOUTILIER. 1994. "Effect of Coronary Ablation and Adrenergic-Stimulation on In-Vivo Cardiac-Performance in Trout (Oncorhynchus-Mykiss)." Journal of Experimental Biology 186: 127-143.In fish, catecholamine-induced changes in cardiac performance in vivo are the result of complex interactions between the direct adrenergic effects on the heart and peripheral circulation and the reflex responses to increased ... -
Heart-Rate and Hemolymph Pressure Responses to Hemolymph Volume Changes in the Land Crab Cardisoma-Guanhumi - Evidence for Baroreflex Regulation
BURGGREN, W., A. PINDER, B. MCMAHON, M. DOYLE, et al. 1990. "Heart-Rate and Hemolymph Pressure Responses to Hemolymph Volume Changes in the Land Crab Cardisoma-Guanhumi - Evidence for Baroreflex Regulation." Physiological zoology 63(1): 167-181. doi:10.1086/383509No abstract available. -
Influence of Hypoxia and Adrenaline Administration on Coronary Blood-Flow and Cardiac-Performance in Seawater Rainbow-Trout (Oncorhynchus-Mykiss)
GAMPERL, AK, AW PINDER, and RR GRANT. 1994. "Influence of Hypoxia and Adrenaline Administration on Coronary Blood-Flow and Cardiac-Performance in Seawater Rainbow-Trout (Oncorhynchus-Mykiss)." Journal of Experimental Biology 193: 209-232.To investigate the relationship between cardiac performance and coronary perfusion, cardiovascular variables (Q, Vs, fH, PDA) and coronary blood flow (q(cor)) were measured in rainbow trout (Oncorhynchus mykiss) (1.2-1.6 ... -
Larval cardiorespiratory ontogeny and allometry in Xenopus laevis
Orlando, Kent, and Alan W. Pinder. 1995. "Larval cardiorespiratory ontogeny and allometry in Xenopus laevis." Physiological zoology 68(1): 63-75. doi:10.1086/physzool.68.1.30163918Very little is known about the early development of cardiorespiratory regulatory mechanisms in newly hatched amphibian larvae. We tested whether early cardiovascular responses to hypoxia reflect local flow regulation in ... -
Oxygen transport in egg masses of the amphibians Rana sylvatica and Ambystoma maculatum: Convection, diffusion and oxygen production by algae
Pinder, Alan W., and Stephen C. Friet. 1994. "Oxygen transport in egg masses of the amphibians Rana sylvatica and Ambystoma maculatum: Convection, diffusion and oxygen production by algae." Journal of Experimental Biology 197: 17-30.Many amphibians lay their eggs in gelatinous masses up to 10-20 cm in diameter, posing problems for diffusive oxygen delivery. Oxygen may also be provided by water convection between eggs or by oxygen production by endogenous ... -
The respiratory development of Atlantic salmon .1. Morphometry of gills, yolk sac and body surface
Wells, PR, and AW Pinder. 1996. "The respiratory development of Atlantic salmon .1. Morphometry of gills, yolk sac and body surface." Journal of Experimental Biology 199(12): 2725-2736.During development from larva to juvenile in Atlantic salmon, Salmo salar, there is a change in the anatomical potential for gas exchange among gills, body skin and yolk sac as the larvae resorb yolk, grow and develop ... -
The respiratory development of Atlantic salmon: II. Partitioning of oxygen uptake among gills, yolk sac and body surfaces
Wells, Patrick R., and Alan W. Pinder. 1996. "The respiratory development of Atlantic salmon: II. Partitioning of oxygen uptake among gills, yolk sac and body surfaces." Journal of Experimental Biology 199(12): 2737-2744.During post-hatch development of Atlantic salmon (Salmo salar L.), O-2 uptake partitioning changes from primarily cutaneous to primarily branchial. Over 80% of post-hatch O-2 uptake was cutaneous, with the yolk sac responsible ...
