Tiny populations of invasive species such as Asian carp start their domination of new ecosystems by hanging out at local landmarks, according to a new study published in the journal Theoretical Ecology this week.
Understanding how species use these local hotspots can play a key role in how officials approach population control for conserving endangered species and controlling invasive ones.
“We recently found that only ten Asian carp are needed to establish a population in the Great Lakes,” said Kim Cuddington, an ecology professor from the University of Waterloo. “But then we asked, if there are so few individuals initially, how do they find a mate and create an ecological disaster?”
