A dramatic juvenile population shrinkage of T. tridentatus was recorded from the nursery creché site closest to a new bridge built in 2007 2.5 km away.

Juveniles of Carcinoscorpius rotundicauda expanded their local range with more individuals at the station farthest away from the newly built bridge 3.5 km away.
