Harlequin frog rediscovered in remote region of Colombia

Discovery made possible through The Conservation Leadership Programme

After 14 years without having been seen, several young scientists supported by the Conservation Leadership Programme (CLP), have rediscovered the Carrikeri Harlequin Frog (Atelopus carrikeri) in a remote mountainous region in Colombia.

The critically endangered Carrikeri Harelquin frog was recently rediscovered by the Project Atelopus team in the Sierra Nevada de Santa Marta Mountains in Colombia’s Magdalena department. Colombia is one of the world’s richest countries in amphibian diversity with more than 583 species. Unfortunately, in the past several years, there has been a decline in amphibian populations especially in higher elevations in Colombia.

“By discovering that the endangered frog still exists, we hope it will show how important conservation is,” said Luis Alberto Rueda, scientist for the Project Atelopus team who led the expedition. “And we plan to continue with our research so that we can better assist in helping to ensure that this frog will not become extinct.”

In addition to Rueda, who is part of the GECOH (Grupo de Ecofisiología, Comportamiento y Herpetologia) of the University of the Andes, the individuals who are part of the Atelopus team of scientist include: Oswaldo Cortes, Giovanni Chaves, Erika Salazar, Jose Gil, Sergio Pulido, Astrid Nossa, Fabian Tavera, Jenny Gallo, Ximena Villagrán and Nidia Rodriguez members of the Ecodiversidad Colombia Foundation (

The Carrikeri Harelquin frog is native to the Sierra Nevada de Santa Marta Mountains in Colombia’s Magdalena province. The frog lives in the páramo habitat at an attitude of 4,000 meters and is approximately five centimeters in size. This population is unique since it possesses orange markings, which are unusual for this species. Páramo is a neotropical grassland ecosystem located in high elevations between the upper forest line (about 3,100 meters in altitude) and the permanent snow line (about 5,000 meters). Nearly 57 percent of this ecosystem worldwide is found in Colombia.

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
