This simple illustration is only part of the carbon cycle, increased calcification will remove carbon dioxide from the water, allowing for the dissolution of more gas.

Increased calcification won't be much help removing CO2 from the water.

Furthermore in contrast to researchers arguing rising atmospheric CO2 will inhibit calcification, increased photosynthesis not only increases calcification, paradoxically the process of calcification produces CO2 and drops pH to levels lower than predicted by climate change models.

In this study, averaged across all generation points, each coccolithophore cell increased its calcification rate (26 %) and calcium carbonate quota (26 %) in the future ocean treatment (figures 2a and 3a), and the total concentration of calcium carbonate in the culture (PIC l − 1) increased 18 % in the future ocean condition (table 4).

Not exact matches

Some crustaceans have been observed with increased amounts of calcification in their exoskeletons in response to ocean acidification, Taylor said.

While these results indicate that coccolithophore calcification might increase under future ocean conditions, the researchers say that it's still unclear «whether, or how, such changes might affect carbon export to the deep sea.»

Blood vessel calcification may put people who develop recurrent kidney stones at increased risk of heart disease, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN).

The team found that people with kidney stones had more calcification in the abdominal aorta, which could explain their increased risk for heart disease.

There is, therefore, much current interest in how coccolithophore calcification might be affected by climate change and ocean acidification, both of which occur as atmospheric carbon dioxide increases.

Previous studies showed that the coral calcification process has a diel rhythmic cycle of increasing rates towards midday, and then decreasing towards dusk (Gutner - Hoch et al., 2016; Schneider et al., 2009).

Reduced food supply owing to lower POC fluxes could exacerbate these impacts because the metabolic cost of increased rates of calcification become greater as pH declines (Wood et al., 2008).

One of the most critical effects of increasing ocean acidity relates to the production of shells, skeletons, and plates from calcium carbonate, a process known as 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.

During the entire period of simulation, net reef calcification decreased although increasing seawater temperature mitigated effects of reduced CO2 emission and the resulting decrease of the pH values on reef calcification.

The calcification risk declined steadily as the number of sleep hours increased, even after the researchers accounted for participants» age, sex, race, level of education, whether or not they smoked, and whether or not they had sleep apnea, a sleep disorder that interrupts breathing and raises blood pressure and heart risk.

Future studies should directly investigate whether exercise increases the activation of vitamin K - dependent proteins, but it seems reasonable to suggest that part of the reason exercise promotes cardiovascular health may be because it ensures a more abundant supply of carbon dioxide, which vitamin K uses to activate proteins that protect our heart valves and blood vessels from calcification.

Without sufficient amounts of vitamin K2, undercarboxylated osteocalcin and MGP can lead to increased coronary calcification and cardiovascular disease.

There are over 25 published studies confirming that deficiencies of K2 are correlated with increased arterial calcification and that prescriptive dosing with vitamin K2 can prevent this.

So topical vasodilators and magnesium oil which reduces calcification (in turn increasing blood flow!).

They also point out that mutations that impair the «non-essential» vitamin K dependent proteins lead to bone fragility, arterial calcification, and increased cancer rates [3]-- all «age - related diseases.»

The goal of the massages / exercises is to reduce fibrosis and calcification of the scalp, whilst increasing blood flow and elasticity.

A cataract, which is technically an increased opacification and calcification of the lens in the eye, can occur at any age.

Other, but rarer, causes of metastatic calcification include kidney disease (this is the most common cause in cats), malignant tumors producing abnormal hormones that increase blood calcium concentrations (e.g. tumors of the lymphoid system and glands of the anal sac), diabetes mellitus and lung disease.

The most probable immediate cause is an increase in the blood enzyme lipase, which leads to degeneration of the subcutaneous adipose tissue (fat), followed by calcification of the degenerated tissue.

Free cartilage flaps can lodge in joints and may increase in size with calcification becoming «joint mice» which can be seen on radiographs.

Calcification takes energy, so increased biological energy needed to form and maintain deep sea coral structures may diminish the corals» other biological processes, including reproduction.

All species studied have shown a decline in calcification with increasing pCo2.

On the other hand the paper reports that increased CO2 had a negative impact on calcification in 21 cases out of 25 studied positive in 2 and mixed in the remaining 2.

The closest they come to saying this is «in four of the 18 species (limpets, purple urchins, coralline red algae, calcareous green algae), net calcification increased relative to the control under intermediate CO2 levels (605 and 903 ppm), and then declined at the highest CO2 level (2856 ppm)».

Source: Nature, Reduced Calcification of Marine Phytoplankton in Response to Increased Atmospheric CO2, Issue 407 p. 364 -367

Community calcification decreased as a function of increasing pCO2 and decreasing Î © arag.

One of the dangers identified by the report is a reduction in calcification of coral and other marine organisms as a result of anthropogenic climate change and in particular increased CO2 emissions.

Factors that had the greatest effect on calcification were CO2 removal and subsequent generation of alkaline pH. As CO2 was removed, growth medium pH increased and soluble Ca2 + was removed from solution.

Conversely without photosynthesis, nighttime respiration and calcification increase surface CO2 concentrations and lower pH. Reefs benefit because those processes replenish the depleted CO2 required for photosynthesis on the following day.

The resulting increase in respiration and calcification caused an «acidification event».

Lower calcification rates would reduce the alkalinity pump, reduce surface CO2 and increase the buffering capacity of surface waters.

Coral bleaching and slowing of coral calcification already are causing mass mortalities, increased coral disease, and reduced reef carbonate accretion, thus disrupting coral reef ecosystem health [40], [124].

Specifically, the increase in CO2 and HCO3 — availability might increase photosynthetic rates in some photosynthetic marine organisms, and the decrease in CO32 — availability for calcification makes

Elevating pCO2 concentration and shifting nitrogen source have a synergistic effect on calcification [24], and here we indicate that the responses of E. huxleyi to elevated pCO2 might be offset by simultaneously increasing temperature.

It is therefore unlikely that cell size is responsible for the increased PIC content and calcification rate in the future ocean treatment.

Therefore, although our results suggest that coccolithophore calcification will increase in future ocean conditions (table 6), it is unclear whether, or how, such changes might affect carbon export to the deep sea [7,8].

Cells increased inorganic carbon content and calcification rate under warm and acidified conditions compared with ambient conditions, whereas organic carbon content and primary production did not show any change.

For example, De Bodt et al. [22] found a 57 % increase in photosynthetic rate under elevated pCO2 that was non-statistically significant (table 6), whereas Langer et al. [15] found a 3 % increase in calcification rate under elevated pCO2 that was statistically significant (table 6).

Therefore observed increases in energetic costs are more likely linked to cell homeostasis rather than calcification as previously thought.
