Invasive Species To Blame for Collapse of Vital Ecosystem, Scientists Confirm
AURORA, Colorado — October 26, 2023, 10:00 AM MDT — A team of ecologists from the University of Colorado has confirmed that the rapid collapse of a critical freshwater ecosystem in the Rocky Mountain region is directly attributable to the unchecked proliferation of an invasive species, according to a study published Thursday in the journal Nature Ecology & Evolution. The investigation focused on High Mountain Lake, a formerly pristine alpine body of water that has seen its native amphibian and insect populations decline by more than 90 percent over the past five years.
The research concluded that the invasive species, identified as the spiny water flea (Bythotrephes longimanus), was introduced into the lake through contaminated fishing gear. The findings indicate that the invasive species has outcompeted native zooplankton for food sources, thereby disrupting the entire aquatic food web and leading to a dramatic reduction in water clarity. Scientists warn that the invasive species’ impact could serve as a blueprint for similar ecological disasters across the Northern Hemisphere if preventative measures, including rigorous boat and gear inspections, are not uniformly enforced. The United States Geological Survey has declared this invasive species incident a level-three ecological emergency, the second-highest classification, citing the irreversible loss of endemic biodiversity.
