Sentences with phrase «between calcification»

In addition, they state that there was «no significant correlation between calcification rate and seawater aragonite saturation (Ωarag)» and «no evidence of CO2 impact on bleaching.»

Not exact matches

In women, aortic calcification appears earlier than coronary artery calcification, and thus may be a more sensitive indicator of subclinical cardiovascular disease than coronary artery calcification.25 However, a previous Dutch study26 found no significant association between coronary calcification and whether a woman had ever compared with never breastfed.

To study this concept, researchers evaluated the association between dietary intake of fruits and vegetables in young adults and the presence of coronary artery calcification (CAC) 20 years later.

There was no association between large HDL - P and coronary artery calcification in either population group.

Hence, it could be suggested that the small differences in the calcification rates observed between 100 mg / L and 200 mg / L calcium additions during the day could be a result of relatively mediocre photosynthetic activities of the endo - symbionts, but this should be further studied.

The calcification rate values (µmol CaCO3 h − 1 cm − 2) were calculated according to the equation: Δ A T 2 ∗ V chamber − V coral T ∗ A coral where ΔAT is the difference in Total Alkalinity (AT) measured between the beginning and the end the incubation period, V is the volume of the chamber or the coral fragment, T is the duration of the incubation and A is the coral surface area.

Toby Tyrrell, Professor in Earth System Science at the University of Southampton and co-author of the study, said: «In the future ocean, the trade - off between changing ecological and physiological costs of calcification and their benefits will ultimately decide how this important group is affected by ocean acidification and global warming.

Similarities between invertebrates and vertebrates regarding the elements associated with calcification process come in agreement with previous reports of Atlan et al. (1997) and Liao et al. (1997).

His lab, the largest at the Buck, has diverse projects underway, including: understanding the link between aging and nutrients, gut function, calcification, circadian clocks and diabetic complications.

Linkages between the buildup of atmospheric CO2 from burning fossil fuels and the slowing of coral calcification due to ocean acidification.

This time they looked at the connections between sleep duration and coronary artery calcification.

Since you state that a decrease in net calcification could result from a decrease in gross calcification, an increase in dissolution rates, or both, you distinguish between these responses and get to the conclusion that the impact of ocean acidification on a creature's net calcification may be largely controlled by the status of its protective organic cover and that the net slowdown in skeletal growth under increased CO2 occurs not because these organisms are unable to calcify, but rather because their unprotected skeleton is dissolving faster.

Lying at the fuzzy interface between physical artist and physical world, Solar's body of work is full of ligaments in fragile tension — mineral abstractions connect with metaphors of calcification and sediment, shaped earth binds with fossilized bone.

There is a potential for both positive and negative feedbacks between the ocean and atmosphere, including changes in both the physics (e.g., circulation, stratification) and biology (e.g., export production, calcification) of the ocean.

There are several feedbacks between decreasing the rate of calcification that organisms do in the ocean, and the carbon cycle.

Goddéris Y, Donnadieu Y, de Vargas C, Pierrehumbert RT, Dromart G 2008: Causal or casual link between the rise of nannoplankton calcification and a tectonically - driven massive decrease in Late Triassic atmospheric CO2?

The decreases in calcification and PIC occur simultaneously with decreases in the observed carbonate ion concentration, suggesting a possible link between acidification and decreasing calcification in this vulnerable region.

Moreover, using the average emission scenario (IS92a) of the Intergovernmental Panel on Climate Change, we predict that the calcification rate of scleractinian - dominated communities may decrease by 21 % between the pre-industrial period (year 1880) and the time at which pCO2 will double (year 2065).

Annual bands were then identified manually between density minima, and the annual extension (cm / year), density (g / cm3 / year), and calcification (extension * density; g / cm2 / year) rates were calculated for the core.

In order to establish a cause - and - effect relationship between acidification and decreased calcification, a team led by Carnegie's Ken Caldeira and including Jacob Silverman (the lead author) and Kenneth Schneider, formerly of Carnegie, compared measurements of the rate of calcification in one segment of Australia's Great Barrier Reef called Bird Island that were taken in between 1975 and 1979 to those made at the neighboring Lizard Island in 2008 and 2009.

Coastal ecosystems may show acidification or basification, depending on the balance between the invasion of coastal waters by anthropogenic CO2, watershed export of alkalinity, organic matter and CO2, and changes in the balance between primary production, respiration and calcification rates in response to changes in nutrient inputs and losses of ecosystem components.

Genome - wide transcriptomic changes between present and future ocean conditions are discussed at the 215 generation point, and qPCR for some genes that have been previously identified as involved with calcification [26] was measured across all generation points.
