Low-oxygen 'dead zones' in North Pacific linked to past ocean warming
Low-oxygen dead zones North Pacific ocean warming
2015/12/7
A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic, conditions that led to vast marine dead zones.Results of the re...
Effect of low oxygen and high carbon dioxide atmospheres on the formation of volatiles during storage of two sweet cherry cultivars
modified atmosphere monoterpenic hydrocarbons alcohols esters
2015/3/17
The aroma profiles of two sweet cherry cultivars Kordia and Vanda were investigated during storage at different oxygen and carbon dioxide levels and at a low temperature using solid phase microextract...
Effect of low oxygen storage conditions on volatile emissions and anaerobic metabolite concentrations in two plum fruit cultivars
plum fruit volatiles ethanol
2015/3/3
By harvest time, small amounts of acetaldehyde were accumulated in the flesh of plums, such as 0.31 mg/l for the cv. Stanley and 1.03 mg/l for the cv. Valjevka. This relative difference in concentrati...
Storage of sweet cherries in low oxygen and high carbon dioxide atmospheres
ethanol acetaldehyde firmness
2015/1/22
Acetaldehyde and ethanol are already present in detectable levels at the time of harvest, under aerobic conditions and in healthy, undamaged fruit. Both metabolites can be detected, at different conce...
Tolerance of plum (Prunus domestica L.) fruits stored in low-oxygen atmosphere
ethanol acetaldehyde low oxygen
2015/1/21
Plum fruits of the cultivars Stanley and Valjevka picked at the beginning of climacteric were stored in different storage atmospheres for 31 days at 3°C. The relations between the O2 and CO2 content d...
Responses of cut carnations to a low oxygen level in the ambient atmosphere
Dianthus caryophyllus L. low oxygen atmosphere
2015/1/20
Carnation (Dianthus caryophyllus L.) flowers were subjected to low oxygen to investigate the physiological effects on flower senescence. The effect of ultra low oxygen (0.6–0.8%) led to low accumulati...
Ethanol content in cut roses at low oxygen atmosphere storage
Rosa hybrida L. ethanol acetaldehyde low oxygen content of sugar
2015/1/20
Low oxygen atmosphere is beneficial for preservation of fresh cut roses. Flower tolerance to specific atmosphere yielding anaerobic products was determined. A suitable gas mixture of ULO conditions (0...
Experimental evidence of a low-oxygen refuge for large zooplankton
Experimental evidence a low-oxygen refuge large zooplankton
2014/4/4
We tested the hypothesis that hypoxic zones in the metalimnion and hypolimnion of lakes can provide a refuge against fish predation for large zooplankton. Experiments were run in a large indoor mesoco...
Response of Sesame (Sesamum indicum L.) to Low Oxygen Concentration during Germination
Germination Hypoxic stress Sesame Sesamum indicum L.
2009/7/29
Screening of crop varieties tolerant to a low oxygen environment caused by heavy rain has become an important work in monsoon Asia countries in recent years. We examined the growth of sesame (Sesamum ...
Langmuir circulations disturb the low-oxygen refuge of phantom midge larvae
Langmuir circulations disturb the low-oxygen refuge phantom midge larvae
2014/6/9
The previously unknown effects of wind-induced Langmuir circulations on the distribution of phantom midge larvae (Chaoborus flavicans) were studied by echosounding. The study was carri...
