Researchers tracked more than 2,000 plant communities in Arctic over four decades, and found that some species thrived while others declined.<\/p>\n\n\n\n

In the tundra, there\u2019s no clear winner<\/em><\/h2>\n\n\n\n

Scientists studying plants in one of the most extreme environments on Earth say the Arctic is indeed changing under the impact of global warming\u2014but not in a uniform way.<\/p>\n\n\n\n

Researchers tracked more than 2,000 plant communities over four decades, and found that some species thrived while others declined. Many locations saw new species flourish, while others lost biodiversity.<\/p>\n\n\n\n

\u201cOur study sheds light on how climate change is reshaping one of the world\u2019s most fragile ecosystems, which is warming at four times the global average,\u201d said lead author Dr. Mariana Garc\u00eda Criado, a postdoctoral researcher in tundra biodiversity at the University of Edinburgh.<\/p>\n\n\n\n

\u201cWarmer temperatures are bringing in more species, but not everywhere. Shrubs are reshaping the Arctic ecosystem, but not universally. In other words, while the plant mix is shifting, the overall composition remains in flux. There are no clear winners or losers.\u201d<\/p>\n\n\n\n

The research, published today in Nature<\/a><\/em>, spanned 2,174 plots across 45 sites from the Canadian High Arctic to Alaska and Scandinavia. A team of 54 researchers from 50 institutions collaborated on the project, part of the International Tundra Experiment (ITEX)<\/a>.<\/p>\n\n\n\n

UBC geography professor Dr. Greg Henry, who helped establish the study\u2019s data collection system, described the research as involving \u201cthousands of hours of fieldwork in remote locations\u2014enduring extreme weather, clouds of biting insects and even the occasional polar bear encounter.\u201d<\/p>\n\n\n\n

But, he added, it\u2019s all worth it. \u201cWe need to do long-term research to understand the Arctic, as ecosystem change starts with plants. When they change, everything follows\u2014including Arctic animals, local and Indigenous communities, and the global carbon cycle.\u201d<\/p>\n\n\n\n

Why it matters<\/h2>\n\n\n\n

Dr. Isla Myers-Smith, a professor at UBC\u2019s faculty of forestry and the University of Edinburgh, says the study underscores just how unpredictable Arctic change can be. \u201cWe\u2019re seeing biodiversity shift in unexpected ways, with some species thriving while others decline,\u201d she explains. \u201cThese shifts are reshaping ecosystems in ways we don\u2019t yet fully understand, making it even more urgent to track what\u2019s happening and prepare for the consequences.\u201d<\/p>\n\n\n\n

Global collaborations help us understand what\u2019s happening, but Dr. Myers-Smith says, \u201cThis isn\u2019t just about tracking change. It\u2019s about acting fast to confront the climate crisis.\u201d
