Humans constantly change and even destroy #ecosystems - what happens then? It's called 'novel ecosystems'. "They now exist as self-sustaining systems. These are wild but changed ecosystems. They have passed some critical threshold which means they are unlikely to ever go back to how they were before." #Hawaii has become a laboratory for #ecologists to study such "freakosystems": bbc.com/future/article/2025040

From 2018: #Native Knowledge: What #Ecologists Are Learning from #IndigenousPeople

From Alaska to Australia, scientists are turning to the knowledge of traditional people for a deeper understanding of the natural world. What they are learning is helping them discover more about everything from melting Arctic ice, to protecting fish stocks, to controlling wildfires.

By Jim Robbins • April 26, 2018

"While he was interviewing Inuit elders in Alaska to find out more about their knowledge of beluga whales and how the mammals might respond to the changing Arctic, researcher Henry Huntington lost track of the conversation as the hunters suddenly switched from the subject of belugas to beavers.

"It turned out though, that the hunters were still really talking about whales. There had been an increase in beaver populations, they explained, which had reduced spawning habitat for salmon and other fish, which meant less prey for the belugas and so fewer whales.

"'It was a more holistic view of the ecosystem,' said Huntington. And an important tip for whale researchers. 'It would be pretty rare for someone studying belugas to be thinking about freshwater ecology.'

"Around the globe, researchers are turning to what is known as Traditional Ecological Knowledge (TEK) to fill out an understanding of the natural world. TEK is deep knowledge of a place that has been painstakingly discovered by those who have adapted to it over thousands of years. 'People have relied on this detailed knowledge for their survival,' Huntington and a colleague wrote in an article on the subject. 'They have literally staked their lives on its accuracy and repeatability.'

"This realm has long been studied by disciplines under headings such as ethno-biology, ethno-ornithology, and biocultural diversity. But it has gotten more attention from mainstream scientists lately because of efforts to better understand the world in the face of climate change and the accelerating loss of biodiversity.

"Anthropologist Wade Davis, now at the University of British Columbia, refers to the constellation of the world’s cultures as the 'ethnosphere,' or 'the sum total of all thoughts and dreams, myths, ideas, inspirations, intuitions, brought into being by human imagination since the dawn of consciousness. It’s a symbol of all that we are, and all that we can be, as an astonishingly inquisitive species.'

"One estimate says that while native peoples only comprise some 4 or 5 percent of the world’s population, they use almost a quarter of the world’s land surface and manage 11 percent of its forests. 'In doing so, they maintain 80 percent of the planet’s biodiversity in, or adjacent to, 85 percent of the world’s protected areas,' writes Gleb Raygorodetsky, a researcher with the POLIS Project on Ecological Governance at the University of Victoria and the author of The Archipelago of Hope: Wisdom and Resilience from the Edge of Climate Change."

Nine months ago, the russians destroyed the Kakhovka Hydro Power Plant, leaving behind a desolate landscape. However, signs of nature's recovery have emerged this spring. #Ecologists are cautiously optimistic. Yet, all this restoration work would have been unnecessary had the russians not committed this act of terror.

#Canada moves to protect #CoralReef that scientists say ‘shouldn’t exist’

Discovery was made after #FirstNations tipped off #ecologists about groups of fish gathering in a fjord off #BritishColumbia

"On the last of nearly 20 dives, the team made a startling discovery – one that has only recently been made public.

"'When we started to see the living corals, everyone was in doubt,' says Cherisse Du Preez, head of the deep-sea ecology program at Fisheries and Oceans Canada. 'Then, when we saw the expansive fields of coral in front of us, everybody just let loose. There were a lot of pure human emotions.'

"Despite existing in absolute darkness, the lights of the submersible captured the rich pinks, yellows and purples of the #corals and #sponges.

"The following year, the team mapped #LopheliaReef, or #q̓áuc̓íwísuxv, as it has been named by the #Kitasoo Xai’xais and #Heiltsuk First Nations. It is the country’s only known living coral reef.

"The discovery marks the latest in a string of instances in which Indigenous knowledge has directed researchers to areas of scientific or historic importance. More than a decade ago, #Inuk oral historian Louie Kamookak compared #Inuit stories with explorers’ logbooks and journals to help locate Sir John Franklin’s lost ships, HMS Erebus and HMS Terror. In 2014, divers located the wreck of the Erebus in a spot Kamookak suggested they search, and using his directions found the Terror two years later."

Why #Ecologists Are Haunted by the Rapid Growth of #GhostForests

A study in North Carolina of dying #trees may represent a foreboding preview of what may come to #coastal #ecosystems worldwide.

by Jim Morrison

"As the ocean intrudes and saltwater rises, it kills trees and creates these ghost forests—bare trunks, and stumps, ashen tombstones marking a once-thriving coastal ecosystem. In North Carolina, #pine, #RedMaple, #sweetgum and bald #cypress forests are being replaced by saltmarsh. Eventually, that saltmarsh will be replaced by open water, a shift that leads to significant and complex costs to the environment and the local economy. The loss of forests will reduce carbon storage, further fueling climate change, and the agriculture industry, timber interests will suffer as saltwater moves inland."

#Global #warming is leading to longer growing seasons worldwide, with many #plants growing earlier in spring and continuing longer in autumn thanks to warmer #temperatures—so is the general opinion. Now, however, plant #ecologists at the University of Basel have been able to show that this is not the case.
