Canada: Climate change could be to blame for increased invasive jellyfish sightings

Published 2024년 9월 3일

Tridge summary

Dr. Florian Lüskow from the University of British Columbia predicts an increase in sightings of the invasive peach blossom jellyfish in B.C. due to climate change. These jellyfish, clones from the same polyp, have been found in 34 locations, with the northernmost sighting in Pavilion Lake. They appear in shallow waters when temperatures exceed 21°C. Dr. Evgeny Pakhomov notes that rising freshwater temperatures could push their range further north, although only male jellyfish have been found, limiting their adaptability. Lüskow suggests using environmental DNA to detect jellyfish in their polyp form and encourages public reporting of sightings.

A University of British Columbia researcher is predicting that sightings of an invasive, freshwater jellyfish could increase rapidly in the wake of climate change. Dr. Florian Lüskow completed his research into the peach blossom jellyfish during his postdoctoral fellowship at UBC's department of earth, ocean and atmospheric sciences. The peach blossom jellyfish clones have been spotted in 34 places in B.C., with a sighting in Pavilion Lake, just west of Cache Creek being the northernmost sighting in the province. The first reported sighting was in August 1990, and they've mainly been found in the Lower Mainland, Vancouver Island and the Sunshine Coast, but more recently there have been sightings further inland in Osoyoos Lake. The paper adds that it cannot rule out peach blossom jellyfish in areas further north or east, but records don't exist. "We know that of the 100 jellyfish examined so far, each has been male comprised of the same genetic material, which means these thousands ...
