Sentences with phrase «of acidification stress»

Less clear are the impacts of acidification stress and multiple stressors on deep - sea fish populations and fisheries production (Rosa and Seibel, 2008).

Not exact matches

Today the vast majority of the populace in industrialized nations suffers from problems caused by the stress of acidosis, because both modern lifestyle and diet promote acidification of the body's internal environment.

Scientists have been warning that decreasing amounts of available oxygen will increase stress on a range of species, even as they also face the effects of rising temperatures and ocean acidification.

Add in the stress of ocean acidification and protecting coral reefs becomes even more important (and challenging).

Unpublished work by Gates, led by the University of Hawaii's Hollie Putnam, shows that adult cauliflower corals (Pocillopora damicornis) exposed to stress during brooding produce larvae with increased resilience to heat and ocean acidification.

During the experiments, the animals shut down parts of themselves when undergoing the stress of ocean acidification, redirecting their energy to new growth.

But this study is the first to probe how the coral microbiome and physiology respond to simultaneous stresses of temperature and acidification.

That's the conclusion of a new study that used measurements of an array of human pressures on the ocean — from acidification to overfishing — to make a map of where those factors combined into stressed - out hotspots, as well as how the combinations of stressors had changed over time.

Local human - made stresses add to the global warming and acidification effects, all of these driving a contraction of 1 — 2 % per year in the abundance of reef - building corals [39].

A reduction of regional stress such as nutrient runoff or the loss of oxygen can mitigate the impact of global stressors like ocean acidification and warming.

Coral reefs are under stress for several reasons, including warming of the ocean, but especially because of ocean acidification, a direct effect of added carbon dioxide.

Corals and other species that depend upon them are also highly vulnerable due to the combined effects of warming ocean water, ocean acidification, and other human - caused stresses.

Joeri Rogelj from the Institute for Atmospheric and Climate Science and a lead researcher of the report, said: «Ocean acidification due to increased atmospheric concentrations of carbon dioxide... will put increasing stress onto marine eco-systems.

Local human - made stresses add to the global warming and acidification effects, all of these driving a contraction of 1 — 2 % per year in the abundance of reef - building corals [39].

Other sources of stress such as nutrient runoff, sedimentation, overfishing, and ocean acidification appear to interact with heat stress to change the bleaching threshold [11], [18], [24], [25].

The discussion in the article and my comment, regarding mass coral bleaching and mortality, is about thermal stress / ocean heat, not acidification (only incidentally related in terms of possible impact on regrowth).

Selina Ward studies the early life history stages of corals and the responses of reproduction and recruitment to environmental stresses such as temperature change, ocean acidification, elevated nutrients and Trichodesmium.

What I concluded is that in the vicinity of human habitation (e.g., occupied coral atolls), other human excesses are currently a source of greater harm than ocean acidification (or heat stress, which is as a separate issue).

Coral reefs are threatened by rising water temperatures, ocean acidification, and sea - level rise.3, 5 Coral reefs typically live within a specific range of temperature, light, and concentration of carbonate in seawater.6 When increases in ocean temperature or ultraviolet light stress the corals, they lose their colorful algae, leaving only transparent coral tissue covering their white calcium - carbonate skeletons.6 This phenomenon is called coral bleaching.

-- Life in the oceans are under severe stress and 90 % of the big fish biomass is already fished out, plus ocean acidification is occurring which threatens entire bio webs.
