Oamenii de știință chilieni avertizează că o muscă arctică s-a reprodus în Antarctica

On Friday, Chilean scientists warned that the Arctic fly Trichocera maculipennis has been observed reproducing in the natural environment of the Antarctic Peninsula, raising concerns of an invasive threat to local species. The observation was made by an expedition of the Chilean research institute Centro Internacional Cabo de Hornos during the latest austral summer, between December 2025 and March 2026, when colonies were found in several caves close to penguin breeding areas. The United Nations, cited by Agerpres via AFP, reported that the Antarctic Peninsula is among the fastest‑warming regions on Earth in the past half‑century, with temperatures rising by almost 3 °C, a change that environmental experts say facilitates the arrival of invasive species. In the previous five years, the presence of Trichocera maculipennis had already been noted in the sewage systems of scientific and military stations in Antarctica, but the current finding marks the first documented natural‑habitat colonisation. Both HotNews and Antena 3 stress that the spread of the fly could endanger native Antarctic fauna, although no specific species have been identified as at risk in the reports.
