TEHRAN, May 23- As Earth's temperatures continue to rise, freshwater ecosystems in the Arctic are becoming unusually warm -- too warm for many native species.

As planet warms, Arctic lakes, rivers will lose their biodiversityTEHRAN, Young Journalists Club (YJC) - According to a report, the trend could cause regional extinctions, resulting in a tremendous loss of biodiversity in Arctic lakes and rivers.

The recently published Arctic Freshwater Biodiversity Report, a product of the Circumpolar Biodiversity Monitoring Program, CBMP, suggests Arctic species are running out of Arctic habitat.

"The findings of the report are alarming. Global warming is reducing the area of the region that can be considered as Arctic," Danny Chun Pong Lau, an ecologist at Umeå University in Sweden, said in a news release. "The consequence is that southern species move northwards and cold tolerant species face possible local extinction when they cannot adapt or compete for resources."

The report was compiled by an international group of climate scientists, biologists, ecologists and conservationists. Using data from dozens of studies and surveys, the report offers an overview of the health of fish, benthic macroinvertebrates, zooplankton, algae, and macrophyte populations across the Arctic.

The first circumpolar database on freshwater biodiversity will make it easier for scientists to track the biological changes caused by climate change.

"The aim is to make knowledge more accessible and easy to update," says Danny Chun Pong Lau. "All data will be available in the Arctic Biodiversity Data Service online database."
