New rainfrog species named in honor of Greta Thunberg

The Rainforest Trust celebrated its 30th anniversary by hosting an auction offering naming rights for new-to-science species. The funds raised are to aid their conservation.

In 2018, Rainforest Trust celebrated its 30th anniversary by hosting an auction offering naming rights for some new-to-science species. The funds raised at the auction benefited the conservation of the newly recognized species. It is estimated that about 100 new species are discovered each year.

The scientific article officially describing and naming the new species, Pristimantis gretathunbergae, was published in Pensoft’s scientific journal ZooKeys.

The international team that discovered the new rainfrog was led by Abel Batista, Ph.D. (Panama) and Konrad Mebert, Ph.D. (Switzerland). The two have collaborated for 10 years in Panama and have published eight scientific articles together and described 12 new species.

The team found the frog on Mount Chucanti, a sky island surrounded by lowland tropical rainforest in eastern Panama. Reaching its habitat in the cloud forest required access via horseback through muddy trails, hiking up steep slopes, by-passing two helicopters that crashed decades ago, and camping above 1000 m elevation. The Chucanti reserve was established by the Panamanian conservation organization ADOPTA with support from Rainforest Trust.

The Greta Thunberg Rainfrog exhibits distinctive black eyes—unique for Central American rainfrogs. Its closest relatives inhabit northwestern Colombia. Unfortunately, the frog’s remaining habitat is severely fragmented and highly threatened by rapid deforestation for plantations and cattle pasture. The Chucanti Reserve where the frog was first found is part of a growing network of natural parks and preserves championed by the Panamanian Government.

The Rainforest Trust auction winner wanted to name the frog in honor of Greta Thunberg and her work in highlighting the urgency in preventing climate change. Her “School Strike for Climate” outside the Swedish parliament has inspired students worldwide to carry out similar strikes called Fridays for Future. She has impressed global leaders and her work is drawing others to action for the climate.

The plight of the Greta Thunberg Rainfrog is closely linked to climate warming, as rising temperatures would destroy its small mountain habitat. The Mount Chucanti region already has lost more than 30% of its forest cover over the past 10 years. Deadly chytrid fungus pose additional threats for its amphibians. Conservation of the remaining habitat is critical to ensure the survival of the frog. The important work in Panama by ADOPTA and Rainforest Trust globally to protect rainforests is critical to the survival of this frog and many other endangered species.

Greek heroic deity Prometheus now has a namesake in a new tiny rain frog from Ecuador

Prometheus, the mythological Greek heroic deity, has been given a namesake in a new species of tiny rain frog, discovered in southwestern Ecuador. The name was chosen by the international team of scientists, led by Dr Paul Szekely, Ovidius University, Constanta, Romania, in acknowledgement of the Prometeo program, funded by the Ecuadorian government.

The description of this new species (Pristimantis prometeii) is the result of the cooperation between three Romanian Prometeo investigators affiliated with the Universidad Tecnica Particular de Loja and Universidad Nacional de Loja, and two Ecuadorian specialists from Pontificia Universidad Catolica del Ecuador. The full study is available from the open access ZooKeys.

During the day, frogs of the new species were found hiding in flowering plants, while at night — perching on leaves at low heights in well preserved cloud forests. They grow to 2-3 cm with the females being larger than the males.9121_Adult female in life img 2

The newly described species is part of a group of frogs called Terrarana (meaning ‘Land or terrestrial frogs’). This is a lineage of frogs that has evolved directly developing eggs, which are deposited in terrestrial habitats. Unlike other frogs, these ones do not have an aquatic tadpole stage and the embryos develop directly into froglets on land.

The newly described species is only known from Reserva Biologica Buenaventura, southwestern Ecuador, at elevations between 878 and 1082 m. This reserve is privately owned by the Jocotoco Conservation Foundation. The reserve has at least another four endemic species of amphibians, reptiles, and birds.

With more than 470 species, the directly developing rain frogs of the genus Pristimantiscontinue to surprise everyone.

“While new species are described every year, there are over a hundred discovered over the last decade only,” remind the authors.

Singing in the rain: A new species of rain frog from Manu National Park, Amazonian Peru

A new rain frog species has been described from Amazonian Peru and the Amazonian foothills of the Andes. The frog, given the name Pristimantis pluvialis, was found by researchers from Southern Illinois University Carbondale, the University of Michigan, and the National University of San Antonio Abad of Cusco in Peru. The discovery is published in the open access journal ZooKeys.

Several individuals of P. pluvialis were found during nocturnal surveys near Manu National Park, a region recognized as having the highest diversity of reptiles and amphibians of any protected area.

The species has also been collected within the private conservation area Bosque Nublado, owned by the Peruvian NGO Perú Verde, and within the Huachiperi Haramba Queros Conservation Concession, the first such type of concession granted to a native community in Peru.

The new species is likely found within the park as well, bringing the number of known amphibian species in this area to 156. Similarly to other species within its genus, which is among the largest vertebrate genera, the new rain frog exhibits direct development. This means that it is capable of undergoing its entire life cycle without a free-living tadpole stage.

It can be distinguished from other members of its genus by call, skin texture, and the presence of a rostral papilla. It was given the name “pluvialis”, translatable to “rainy” from Latin, to denote the incredibly rain-soaked habitat it lives in (>8 meters of rain yearly), and because it was found calling only after heavy rains.

Unfortunately, when a fungal disease, known as the amphibian chytrid fungus, arrived in the area back in the early 2000s, many frog species in and around the region began to decline. Out of the studied ten individuals of the presently described new species, four were found to be infected. However, the impact of the disease on these particular rain frogs is still unknown, and their numbers do not seem to have decreased.Image 3

“This discovery highlights the need for increased study throughout the tropics, for example Manu NP and its surrounding areas have been well studied, but despite these efforts, new species are being continuously discovered,” points out first author Alex Shepack, a PhD student in the laboratory of co-author Dr Alessandro Catenazzi at Southern Illinois University.

Finding the real treasure of the Incas: Two new frog species from an unexplored region

Inaccessibility and mysticism surrounding the mist-veiled mountains of the central Andes make this region promising to hide treasures. With an area of 2197 km2, most of the Llanganates National Park, Ecuador, is nearly unreachable and is traversed only by foot. However, fieldwork conducted by researchers from the Museo de Zoología at Catholic University of Ecuador resulted in the discovery of a more real and tangible gem: biodiversity.

Among other surprises, during their expeditions the researchers discovered two new species of rain frogs, formally named P. llanganati and P. yanezi. The new species are characterized by the spiny appearance typical of several species inhabiting montane forests. The study was published in the open access journal ZooKeys.

The new rain frogs belong to the megadiverse genus Pristimantis. They are direct-developing frogs, which means that they lack a tadpole stage and therefore do not undergo metamorphosis.Amphibia

The Neotropical Andes houses a spectacular radiation of Pristimantis, especially in the Montane Forests of the eastern slopes of the Ecuadorian Andes. The species richness of this genus is still underestimated as a consequence of their cryptic morphology and the still sparse amphibian inventories in unexplored regions such as the Llanganates National Park.

The discovery reminds the authors of a mystic local legend dating from the 16th century, when the Inca Empire fell into the hands of Spanish conquerors. Word has it that in exchange for the young emperor’s life, Atahualpa, Incas offered to fill an entire room with tons of gold. However, the Spaniards broke their promise and the emperor was executed. A small group of loyal Incas led by General Rumiñahui decided to hide both, the mummy of Atahualpa and the gold, in the depths of the jungle of the Llanganates National Park.
