根据第一段“The last time CO2 levels were as high as today, ocean waters drowned the lands where big cities like Houston, Miami, and New York City now exist.(上次二氧化碳浓度达到今天的水平时,海水淹没了休斯敦、迈阿密和纽约等大城市现在所在的土地。)”以及第二段“It’s a time called the ...
An abstract of the conference paper "Effects of high levels of CO2 on gene expression in two different genotypes of Fagus sylvatica," by Donatella Paffetti and colleagues is presented.Paffetti, DonatellaMaren, OlbrichFladung, MatthiasErnst, Dieter...
A novel root‐to‐shoot stomatal response to very high CO2 levels in the soil: electrical, hydraulic and biochemical signalling 来自 Semantic Scholar 喜欢 0 阅读量: 39 作者:JA Lake,HJ Walker,DD Cameron,BH Lomax 摘要: Investigations were undertaken in the context of the potential environmental ...
Climate and CO2levels have always varied together. During past ice ages CO2levels were low, and during warm periods CO2was higher. The rock “weathering thermostat” prevents a runaway climate on very long timescales. Climate Myth: CO2 was higher in the past ...
Using ice cores drilled in Greenland and Antarctica, scientists havea pretty good recordof how the composition of Earth’s atmosphere has fluctuated over the last 800,000 years. That’s why scientists know carbon dioxide levels are higher than they’ve ever been in that amount of time. ...
Thus, high levels of CO2 drive TCA cycle reactions in the direction of acetyl-CoA and pyruvate production. The authors suggest that the reversed TCA cycle may have been important for early life, when the atmosphere was rich in CO2. This is a preview of subscription content, access via your...
“CO2in the atmosphere has gone up 100 ppm in my lifetime,” said Kathleen Benison. a geologist at West Virginia University who researches past climates. “That’s incredibly fast geologically.” “You don’t have to be a scientist to realize something totally unusual is going on, and that...
4 Metabolites in H. maritima growth medium. a, Sulfide production during growth under mixotrophic conditions (CO2, H2, S0 and 0.2 g l−1 yeast extract). b, Concentrations of potential fermentation products and some amino acids in the medium after inoculation and after 1, 2 and 3 days of...
aHigh levels of oxygen in plant cells can disrupt photosynthesis and also cause phototorespiration-an inefficient form of the dark reactions in which O2 is fixed rather than CO2 and no carbohydrate is produce. 正在翻译,请等待...[translate]...
Simulated declines in CO2 sequestration and biome stability were translated to economic terms by a) using social costs of carbon estimates for climate regulation and b) transferring ES values from other studies for habitat services. Furthermore, we considered influences of price levels by calculating ...
