Acidification in the Rat Proximal Jejunum
Acidification of solutions by rat proximal jejunum was investigated in everted sacs, segments and in perfused in vivo loops. Acidification which declines down the jejunum, increased with increasing mucosal glucose concentration, reaching a maximal value. Derived Michaelis-Menten data gave an …

Ocean acidification: physiological response from fish to cell
… response to a simulated predicted ocean acidification scenario at the functional and molecular level. Using the European sea bass (Dicentrarchus labrax) as an animal model, the present study’s main focus was on the effects of high pCO2 levels in the intestinal bicarbonate handling …

Doxorubicin Inhibits Cardiomyocyte Autophagic Flux by Suppressing Lysosomal Acidification
… the site of block as a defect in lysosome acidification. To test the functional relevance of doxorubicin-triggered autolysosome accumulation, I studied animals with diminished autophagic activity due to haploinsufficiency for Beclin 1. Beclin 1+/- mice exposed to doxorubicin manifested …

Ecology of acidification and recovery in Welsh upland streams
… low pH. Field experiments tested the effects of acidification on two key processes in stream ecosystems, benthic algal grazing and leaf decomposition. Grazer impacts on algal abundance were generally feeble and largely unaffected by acid stress. Leaf litter decomposition was impaired by …

Ocean acidification and its effects upon fitness in nereidid polychaetes
… dramatic consequences. Data show that if ocean acidification continues as predicted, marine chemoreception will have to adapt rapidly with potentially profound consequences for marine life and animal interactions.It is clear from this investigation that P. dumerilii and A. succinea are not …

Spectroscopy as a tool for the management of soil acidification
… improve the measurement and management of soil acidification. The project assessed acidic cropping soils from trial sites established in the mid-Northern and Yorke Peninsula cropping regions of South Australia. The ability of Mid Infrared (MIR) soil spectroscopy in combination with Partial Least …

Adaptive Tolerance to Ocean Acidification in the Marine Sponge: Chondrilla nucula
… Revolution has led to a 30% increase in ocean acidification over pre-industrial levels. Although most ocean acidification research thus far has focused on calcifying organisms such as corals, the potential of this increase in acidity (H+ ions) to cause acid-base imbalances in soft-bodied …

Satellite-based Assessments Of Ocean Acidification For The Hawaiian Islands Region
Ocean acidification (OA) is a growing global environmental concern with impacts affecting regions all over the world, including remote areas such as Hawai‘i. OA is gaining worldwide attention due to environmental impacts including the detrimental effects of OA on coral reefs. Increased …

OCEAN ACIDIFICATION: UNDERSTANDING THE COASTAL CARBON PUMP IN A HIGH CO2 WORLD
Since the 1800s, carbon dioxide emissions due to human activities have contributed significantly to the amount of carbon in the atmosphere. Approximately a third of this carbon is absorbed by the ocean, through air-sea fluxes at the ocean surface (Sabine, 2004). Increased CO2 has changed the carbon …

Response of pteropod and related faunas to climate change and ocean acidification
Recent concern over the effects of ocean acidification upon calcifying organisms in the modern ocean has highlighted the aragonitic shelled thecosomatous pteropods as being at a high risk. Laboratory studies have shown that increased pCO2, leading to decreased pH and low carbonate concentrations, …

Impacts of ocean acidification and other (global change) stressors on marine invertebrates
… that C. carinata could tolerate in future acidification scenarios, estuarine isopod was exposed to four pH treatments (control: 7.9; 7.5, 7.0, 6.5). Seawater acidification had a significant impact on the longevity of C. carinata, where the population density decreased significantly when …

Adverse Effects of Crack/Cocaine to Marine Organisms Affected by Acidification Conditions
… is causing global warming and ocean acidification. The inorganic carbon system is one of the most important chemical equilibria in the ocean and is largely responsible for controlling seawater’s pH. Once pH values decreased, organic compound may also suffer some alterations in …

Crossing the Ecoline: a visual response to increasing levels of ocean acidification
… is a visual response to changing levels of ocean acidification. My art making is informed by the processes of dispersal and dissolution that occur at the point where the absorption of carbon dioxide takes place between the atmosphere and the ocean. This project is of an interdisciplinary nature …

Scale prevention in sea water evaporators. Part III. Decarbonation, filtration, and acidification
… evaluate the complete decarbonation-filtration-acidification process for scale prevention on sea water distillation equipment.

Ocean acidification influences on physiology and epigenetics in the Pacific oyster (Crassostrea gigas)
As ocean acidification continues to impact marine ecosystems at unprecedented rates, phenotypicplasticity may allow organisms to withstand more stressful conditions. Genomic methods can elucidate molecular mechanisms that contribute to phenotypic plasticity, allowing for a deeper understanding of …

Living costs of ocean acidification and warming in herbivorous gastropods and their adaptations
… in future marine ecosystems, including ocean acidification and warming. In addition, extreme climatic events, such as heatwaves, will become more prevalent and persistent due to global warming. Thus, extensive studies have been conducted to determine how ocean acidification and warming affect …
