10 new amphibian species discovered in Colombia

Secluded safe haven for frogs as global extinctions rise

Scientists today announced the discovery of 10 amphibians believed to be new to science, including a spiky-skinned, orange-legged rain frog, three poison dart frogs and three glass frogs, so called because their transparent skin can reveal internal organs.

The species were discovered during a recent Rapid Assessment Program (RAP) expedition in Colombia's mountainous Tacarcuna area of the Darien, near the border with Panama. The expedition was led by herpetologists from Conservation International (CI) in Colombia and ornithologists from the Ecotrópico Foundation, with the support of the local Emberá community of Eyakera.

Over a period of three weeks, the scientists identified approximately 60 species of amphibians, 20 reptiles and almost 120 species of birds, many of them apparently found no where else.

The potentially new species of amphibians include three glass frogs of the Nymphargus, Cochranella and Centrolene genus; three poison dart frogs of the Dendrobatidae family (Colostethus, Ranitomeya and Anomaloglossus genera), one harlequin frog of the Atelopus genus, two species of rain frogs of the Pristimantis genera and one salamander of the Bolitoglossa genus. Colombia holds one of the most diverse amphibian communities in the world, with 754 species currently recorded.

In addition to the new discoveries, the expedition recorded the presence of large mammals such as Baird's tapir (Tapirus bairdii), listed on the IUCN Red List as Endangered in Colombia, and four species of monkeys, including Geoffroy's spider monkey (Ateles geoffroyi), Geoffroy's tamarin or red crested bare-faced tamarin (Saguinus geoffroyi), white-throated capuchin or Gorgona white-fronted capuchin (Cebus capucinus) and the mantled howler monkey (Alouatta palliata). They also found populations of white-lipped peccary (Tayassu pecari).

Other surprising findings included the presence of Central American species recorded for the first time in the northern area of South America, including a salamander (Bolitoglossa taylori), a rain frog (Pristimantis pirrensis), a small lizard (Ptychoglossus myersi) and a snake not yet identified.

"Once more we confirm we are leaders in natural diversity and not only in our region but in the world. Without a doubt this discovery represents a great milestone for science and human health," said Colombia's Minister of Environment Juan Lozano.

Scientists consider amphibians important indicators of ecosystem health. With porous, absorbent skin, they often provide early warnings of environmental degradation caused by acid rain, or contamination from heavy metals and pesticides that can also harm people. Amphibians help control the spread of many diseases, such as malaria and dengue fever, because they eat the insects that deliver these diseases to human populations. In addition, amphibians are extremely susceptible to unusual weather variations, with many species impacted by climate change.

"Without a doubt this region is a true Noah's Ark. The high number of new amphibian species found is a sign of hope, even with the serious threat of extinction that this animal group faces in many other regions of the country and the world," said Jose Vicente Rodriguez-Mahecha, Scientific Director of CI-Colombia.

This area of the Darien is isolated from the Andes Mountain range. It is recognized as a center of endemism and valuable for its high biological diversity. Historically it has served as a bridge for exchange of flora and fauna between North and South America.

Although the natural cover of the Darien region is currently relatively undisturbed, it faces many threats and is undergoing rapid landscape transformation, mainly due to selective wood extraction, extensive cattle ranching, illicit crop cultivation, hunting, mining and habitat fragmentation. Between 25 and 30 percent of the natural vegetation of the area is being deforested, especially in the lowlands and alluvial plains.

Results of the expedition are expected to contribute to strengthening the protected area status that applies to almost all the Colombian Darien region, and to help bring about the declaration of a new protected area in the Tacarcuna hills. In addition, an important goal is to support initiatives that guarantee the land rights for the indigenous Emberá community of Eyakera through the creation of an Indigenous Reserve, and the development of management plans appropriate for the area and its population.

The identity and names of the new found species will be presented to the scientific community and the environmental authorities to evaluate their conservation status or risk of extinction.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
