A new paper published today, led by Chicago's Shedd Aquarium, reveals how volunteers across Illinois, Wisconsin and Michigan enabled researchers to gather seven years of data on the spawning migrations of suckers, an understudied yet essential group of freshwater fishes. Using observations collected by trained members of the public, the collaborative team of researchers have discovered that temperature is the primary trigger for sucker spawning migration, which can help inform conservation strategies in light of a changing climate.
