When talking about climate change, discussion tend to focus on rising global mean temperatures. But the shifts in the climate system have other effects, too. Oceanographic models predict an increase of extreme short-term events such as heat waves or upwelling events. With an experiment lasting several months over the summer of , scientists at GEOMAR Helmholtz Centre for Ocean Research Kiel, together with colleagues from Portugal and Bermuda, investigated whether short-term heat waves could have a lasting impact on coastal ecosystems.
When talking about climate change, discussion tend to focus on rising global mean temperatures. But the shifts in the climate system have other effects, too.

With an experiment lasting several months over partnersuche borken summer ofscientists at GEOMAR Helmholtz Centre for Ocean Research Kiel, together with colleagues from Portugal and Bermuda, investigated whether short-term heat waves could have a lasting impact on coastal ecosystems.
He is the lead author of the study, which has recently been published in the international journal Global Change Biology. The partnersuche borken was conducted in the Kiel Partnersuche borken Benthocosms KOBswhich consist of a total of 12 experimental chambers installed on a pontoon directly on the shores of the Kiel Fjord. In each of these chambers the researchers held partnersuche borken community of seagrass, bladderwrack and their associated animals such as snails, crabs and mussels, for almost four months.
The KOBs are special in that the researchers partnersuche borken precisely control various environmental parameters in each chamber, including seawater temperature, salinity, pH or oxygen content. In the course partnersuche borken the study, the participants simulated the temperatures of the year within the KOBs.
That's why this partnersuche borken was a good partnersuche borken for our experiment," says Dr. The organisms in four of the experimental chambers experienced the temperatures. In four chambers, the scientists applied an additional summer heat wave in August. In the last four chambers, the species community experienced two weaker heat waves in June and July, before reaching the severe summer heat wave in August.
About half of the species in the KOBs partnersuche borken clear reactions to the heat waves. Some species showed negative effects, which accumulated over the three heat waves, while other species coped better with the summer heat after experiencing the two spring warming events.
So, if the frequency and intensity of heatwaves increases in partnersuche borken future, there will be winners and losers in coastal ecosystems. The current structure of the species is likely to shift.
However, not all relevant factors have partnersuche borken examined in detail yet. Currently in the Kiel Indoor Benthocosms another long-term experiment dealing with the effects of heat waves bekanntschaften machen französisch partnersuche borken conducted.
Here the focus is on the impact of longer and more severe heat waves. Also in the current experiment in the Kiel Outdoor Benthocosms, warming supplemented by phases of oxygen depletion is an factor.

Incubation chambers with Zostera partnersuche borken seagrass and the associated infauna community in in the KOB. In four of the 12 benthocosms chambers the species community experienced the tempertur curve of blue line. In four chambers, the researchers simulated a summer heatwave in August.
In partnersuche borken last four chambers there were a total of three heat waves during the summer. The Kiel Outdoor Benthocosms. Fees, Cost of living etc. Centre Research Studying Discover. As a result of the ongoing climate change, oceanographic models predict an increase in extreme events such as heat waves. In a long-term experiment, in the Kiel Outdoor Benthocosm experimental facility, scientists at GEOMAR Helmholtz Centre for Ocean Research Kiel have found clear indications that such events on a time scale of a few days or weeks can change coastal ecosystems in the long term.
The results of the study have recently been published in the international journal Global Change Partnersuche borken.
