Chaos of climate change, inside a laboratory 22.5.2017 Deccan Herald - Supplements
Climate change will alter the ecosystems that humanity depends upon in the coming century. But given the complexity of the living world, how can you learn what may happen? A team of Australian scientists has an answer: miniature ecosystems designed to simulate the effect of climate change. The experiments are already revealing dangers that would have been missed had researchers tried to study individual species in isolation. "If you just take one fish and put it in a tank and see how it responds to temperature, you can imagine that's a huge simplification of reality," said Ivan Nagelkerken, an ecologist at the University of Adelaide who is leading the research effort. Testing the effects Yet studying an entire ecosystem in nature, made up of thousands of species, has its own drawbacks. "In nature you have all this complexity, and you never know which factor is really causing the outcome you're observing," Ivan said. Between these two extremes, Ivan and his colleagues have tried to create a happy ...

It's getting hotter: New study shows massive increase in moss growth in Antarctic Peninsula 19.5.2017 DNA: Top News
For the naysayers who don’t believe climate change exists, here’s a reality check: Antarctica’s landscape is transforming from white to green, as plant life on the continent grows like never before. As reported by AFP, scientists, who published a paper in Current Biology, have said they have found a sharp increase in plant growth in the past 50 years. Currently, plant life is 0.3% in what used to be a state dominated by ice.    “Temperature increases over roughly the past half century on the Antarctic Peninsula have had a dramatic effect on moss banks growing in the region,” said co-author Matt Amesbury, of the University of Exeter, adding that if this trend continued, then the peninsula would be a much greener place than it is today. Five moss cores — or column-like samples drilled from the Earth — showed evidence of what scientists called “changepoints,” or points in time after which biological activity clearly increased. Areas sampled included three Antarctic islands — Elephant Island, Ardley Island, ...

Climate change is making algal blooms worse 8.5.2017 Deccan Herald - Supplements
Researchers have long suggested that climate change could mean more damage from algal blooms — runaway growths of algae that can strangle marine ecosystems and devastate coastal economies. Now, a study has examined how warming ocean temperatures have already driven an intensification of blooms around North America — the first time this link has been established at an oceanic scale. Harmful algal blooms can occur when changes in water conditions lead to a huge growth in the number of a particular species of algae. The blooms can produce toxins, become so large that they kill marine life and even turn water a different colour. Research has established that one factor that helps blooms spread is a sudden increase in nutrients such as nitrogen and phosphorus — often from agricultural fertilisers — and it has also linked warming temperatures to individual events. But the broader influence of climate change on these outbreaks is less well-quantified. Longer seasons Christopher Gobler, ...
