Caribbean's 'Chicken Frog' Fights Fungal Threat
14 May
Summary
- The large 'mountain chicken' frog is critically endangered.
- Chytrid fungus poses a severe threat to the amphibian's survival.
- Conservation programs include captive populations and biobanking.
The 'mountain chicken' frog, scientifically known as Leptodactylus fallax, is a large amphibian native to Dominica and Montserrat, now critically endangered. This unique species, once a popular dish due to its taste resembling chicken, is struggling for survival against a devastating fungal disease. The chytrid fungus, Batrachochytrium dendrobatidis, appeared on Dominica in 2002, causing an 85% population drop within 18 months, and later affected Montserrat by 2009.
This fungus attacks the frog's skin, disrupting vital functions and leading to heart failure. Coupled with historical threats of overhunting and habitat loss, the species' rapid decline has led to its 'Critically Endangered' classification by the IUCN. The mountain chicken is distinct for its unusual breeding habits, laying eggs in underground burrows and nurturing its young with trophic eggs.
An international effort, the Mountain Chicken Recovery Programme, is working to prevent the species' extinction. This program includes creating captive populations in European zoos and a dedicated breeding center in Dominica. Scientists are also exploring advanced reproductive technologies and biobanking to preserve genetic diversity. Research into environmental refuges, such as solar-heated ponds that can kill the fungus, is also underway.
