Oxygen consumption of the amphibious snail Pomacea lineata; Influence of weight, sex and environments

1. 1. Under normoxic conditions at 25°C Pomacea lineata, free to move into or out of water, showed an increase in O2 consumption with increase in body size (dry wt), the slope of the log-log plot of these two parameters being b = 0.76. 2. 2. The metabolic rate decreased with weight. 3. 3. Males and females in a sexually receptive state did not exhibit significantly different QO2 values. 4. 4. The metabolic rates of animals when under water using ctenidium did not differ significantly from when out of water using the lung. © 1981.

Chemiluminescence induced in the laser-promoted reaction of ethanol with oxygen

The vibrational multiphoton excitation of ethanol in the presence of oxygen results in chemiluminescent reactions yielding CH* and C*2. The rise times of the chemiluminescence become progressively slower and the intensity increases with ad-O2 pressure. At 15 Torr of O2 the emission duration is longer than 10 μs. © 1983.

Oxygen uptake of active and aestivating earthworm Glosso scolex pa ulistus (Oligochaeta, Glossoscolecidae)

1. 1. The onset of or reactivation from aestivation in the earthworm Glossoscolex paulistus were dependent upon soil moisture. No evidence of temperature effect in the process was found either in field or laboratory data. 2. 2. Oxygen uptake measured in active and aestivating groups revealed remarkable reduction for aestivating earthworms at various temperatures studied. 3. 3. No evidences of temperature compensation in oxygen uptake was found in both groups of earthworms, indicating that reduction in oxygen uptake is the only adaptation for the aestivating G. paulistus. © 1985.

X-ray diffraction investigation of Co(II) ions in borosilicate glasses

The radial distribution functions of cobalt glasses with 6%, 8%, and 14% CoO are compared with those of suitable cobalt-free borosilicate matrices leading to difference distribution curves representative of the cobalt structural arrangement. Analysis of the curves indicates that cobalt ions are surrounded by approximately four oxygen neighbors at the distance expected for fourfold coordination. © 1986 American Institute of Physics.

The respiratory responses of an amphibious snail Pomacea lineata (spix, 1827), to temperature and oxygen tension variations

1. 1. The respiratory responses of Pomacea lineata to short-term (or acute) exposure to temperature and oxygen tension variations were investigated in animals acclimated to 25°C. 2. 2. The respiratory rates increased with rising temperatures; this increase was sharper between 15 and 25°C than at any other temperature interval; a tendency to a plateau in the RT curve was recorded between 25 and 35°C. 3. 3. All animals survived well to 1 hr exposure to the extreme temperatures used (5 and 40°C). 4. 4. In two different experimental approaches, the animals showed ability to regulate the respiratory rate in declining oxygen tensions, at least down to 10% (70.8 mmHg) oxygen. 5. 5. After 1 hr exposure to hypoxic conditions, P. lineata exhibited the pattern of underpayment of the oxygen debt acquired. 6. 6. Six out of ten animals survived after 40 days in anoxia (100% nitrogen). © 1987.
