Arlequin toads (Atelopus) at the Jambatu Centre Research and Conservation of Amphibians in San Rafael, Ecuador. In plastic or glass boxes, with litter, water or rocks – according to the needs of each species – the centre reproduces 34 varieties of toads in captivity, whose populations have decreased dramatically due to the increase in temperature and changes in the conditions of humidity.
