"Joro spiders also appear to be able to capture and feed on at least one insect that other local spiders are not: adult brown marmorated stink bugs, an invasive pest that can infest houses and damage crops."
I remember visiting the Lake Michigan dunes in Indiana in the 70s, only to encounter what appeared to the small me to be mountains of dead alewife. Ten years later, my grandfather took me salmon fishing there. I'd imagine that by now, the ecosystems of the Great Lakes bear little resemblance to what they contained 200 years ago. Sad in a way, but the whole of Earth seems destined to becoming a single, climate-based ecosystem. Island ecologies may survive for a few centuries, but the main continents are going to become very consistent, with all the world-champion species holding sway.
