Predicted relative habitat suitability for three species of snails in three time periods. Bulinus globosus (a, b and c), Biomphalaria pfeifferi (d, e and f), and Lymnaea natalensis (g, h and i). Habitat suitability increases from blue via yellow to red. Left column: present-day climate (1980-1999), mid-column: near-future climate (2046-2065), right column: end century climate (2080-2099).
