Purple harlequin tree frog3/28/2024 ![]() ![]() Dramatic declines in variable harlequin frog populations began in the late 1980s, and they continue to trend downward. ![]() The parasitic chytrid fungus infects the skin of amphibians and has affected many frog species across the globe. “ Release trials may or may not succeed, but the lessons we learn will help us to understand the challenges faced by a frog as it transitions from captivity into the wild,” says Brian Gratwicke, Smithsonian Conservation Biology Institute scientist and international coordination of the Panama Amphibian Rescue and Conservation Project (PARC). Researchers are hopeful that they will provide insight into restoring variable harlequin frog populations to their former glory. Through years of research and breeding, Smithsonian scientists have created a thriving colony in human care and released approx. 500 healthy frogs in Panama’s Colon province Jan. 36: 1-2.The introduction of the amphibian chytrid fungus has decimated populations of the once abundant variable harlequin frogs.

Precipitation is typically not limiting, but may be somewhat seasonal. Epiphytes and climbing plants are also abundant. Rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground.

This anuran is sometimes called the Harlequin Frog, but its relationship within the true toad family (Bufonidae) seems well-accepted (Staniszewski, 1995). ![]() This toad's bright colors undoubtedly serve as a warning of its toxicity (Capula, 1989 Staniszewski, 1995). Fish and Wildlife Service (Levell, 1997).Ī.varius has poisonous glandular skin secretions which are toxic or repellent to potential predators. zeteki, is listed on Appendix I of the CITES Treaty, and is considered endangered by the U.S. Its main habitat is rainforest and these forests are being destroyed at an alarming rate in addition, these little toads may be vulnerable to mysterious fungal infections which seem to be affecting frogs in many parts of the world (Capula, 1989 Staniszewsli, 1995 USGS, 1999). Conservation StatusĪ.varius has begun to disappear from places in Costa Rica where it was common only a few years ago, and is considered an endangered species. They are undoubtedly important insect predators of the forest floor. Harlequin toads are popular in the commercial pet trade, despite being very difficult to maintain successfully (Staniszewski, 1995). Males lack vocal sacs, and attract females by visual displays which can include leg and head twitching, stamping the ground, and hopping in place (Staniszewski, 1995).Ī.varius eats small insects such as flies and gnats (Capula, 1989).
