We are investigating the intertwining histories of mangrove forests and certain gastropods.
Some gastropod molluscs are specially adapted to mangrove environments, which are currently under threat from deforestation and rising sea levels.
Almost all of the living members of the gastropod family Potamididae live in mangrove environments, appearing in the fossil record around the same time mangrove forests first evolved.
Studying the evolution and biogeography of these gastropods gives insights into the history of the mangrove habitat itself.
We use molecular phylogenetics, museum records of distribution and the fossil record to examine these histories.
Mangroves are trees and shrubs that grow in salty coastal regions rich in sediment. Mangrove forests are found in the tropics and subtropics, between 25°N and 25°S latitude.
