#new species of frog

"For over a decade, the Yosemite toad has been recognized as a federally threatened species, after experiencing a 50% population decline during the Rim Fire of 2013.

The wildfire, which encompassed a mass of land near Yosemite National Park, made the amphibian species especially vulnerable in its home habitat. 

Native to the Sierra Nevada, the toads play a key role in the area’s ecosystem — and conservationists stepped in to secure their future.

In 2017, the San Francisco Zoo’s conservation team began working with the National Park Service, Yosemite Conservancy, U.S. Fish & Wildlife Service, California Department of Fish & Wildlife, and the U.S. Geological Survey. 

The goal of all of these stakeholders? To raise their own Yosemite toads, re-establishing a self-sustaining population in the wild. 

“Over the past several years, SF Zoo’s conservation team has been busily raising hundreds of these small but significant amphibians from tadpole stage, a species found only in the Sierra Nevada, for the purpose of reintroducing them to an area of Yosemite National Park where it was last seen 11 years ago,” the zoo shared on social media. 

By 2022, a group of toads were deemed ready for release — and at the end of June of this year [2024], 118 toads were flown via helicopter back to their habitat.

“It’s the first time anyone has ever raised this species in captivity and released them to the wild,” Rochelle Stiles, field conservation manager at the San Francisco Zoo, told SFGATE. “It’s just incredible. It makes what we do at the zoo every day worthwhile.”

Over the past two years, these toads were fed a diet of crickets and vitamin supplements and were examined individually to ensure they were ready for wildlife release.

Zoo team members inserted a microchip into each toad to identify and monitor its health. In addition, 30 of the toads were equipped with radio transmitters, allowing their movements to be tracked using a radio receiver and antenna.

The project doesn’t end with this single wildlife release; it’s slated to take place over the next five years, as conservationists continue to collect data about the toads’ breeding conditions and survivability in an ever-changing climate. They will also continue to raise future toad groups at the zoo’s wellness and conservation center...

While the future of the Yosemite toad is still up in the air — and the uncertainty of climate change makes this a particularly audacious leap of faith — the reintroduction of these amphibians could have positive ripple effects for all of Yosemite.

Their re-entry could restore the population balance of invertebrates and small vertebrates that the toads consume, as well as balance the food web, serving as prey for snakes, birds, and other local predators.

“Zoo-reared toads can restore historic populations,” Nancy Chan, director of communications at the San Francisco Zoo, told SFGATE. 

Stiles continued: “This is our backyard, our home, and we want to bring native species back to where they belong.”

Say hello to Platypelis saikamavo, a new Malagasy species of microhylid frog with a bright yellow belly that we just described!

This species was discovered over TWENTY years ago, but it has taken until now for it to receive a name. Why? Because there was some uncertainty about another species with a yellow belly, Platypelis mavomavo. Fortunately, we were able to solve that problem last year, and thus, P. saikamavo could be described!

(lot of big frog wins)

For the first time in five years, northern corroboree frogs have been spotted in Namadgi National Park by ACT government ecologists.

The species is listed as critically endangered and the government has been attempting to restore their population in the park for more than a decade.

Ecologists have been releasing frogs and eggs into the park as part of a breeding program, but they had not been spotted in the wild since 2019.

This year, 16 male frogs were identified at the Ginini Flats Wetlands site and a further 21 frogs were counted at a lower elevation site in the park. "Having not seen these frogs in the wild since 2019, we were beginning to think all hope was lost, and that the species was close to extinction," Environment Minister Rebecca Vassarotti said.

She told ABC Radio Canberra the frogs were under pressure due to many issues including climate change, habitat loss and the invasive chytrid fungus.

That deadly fungus affects the frogs' skin and stops them from being able to take in water and important salts.

Ms Vassarotti said ecologists had been experimenting with the breeding program and releasing frogs in different areas to see if they could make a difference.

"We've been ... releasing eggs in some other areas in Namadgi, where they hadn't previously been seen," she explained.

"These were at slightly lower elevations. And the reason we were doing that is that they were elevations where there wasn't such an impact of this awful fungus."Ms Vassarotti said this was an "exciting" development but acknowledged there was more work to be done through the breeding program.

"Australia is the extinction capital of the world," Ms Vassarotti said in a statement.

"Way too often, climate change and human impact on the environment has resulted in us losing unique species permanently as they become extinct.

"I've been heartbroken to have to continue to list species as close to extinction.

"The identification of new northern corroboree frogs across a range of sites restores my confidence that we can save this incredible frog that is so unique to our region."

After conservationists dug hundreds of new ponds in the canton of Aargau, amphibian numbers significantly increased.

The European tree frog population in particular "exploded", scientists say.

Scientists hope this method could be used globally as pond building is simple and effective.

Ecuador is one of the most biodiverse places on the planet—a country about the size of Nevada that’s home to more than twice the number of plant and animal species as the United States and Canada combined. Yet its wild spaces—rich in gold, timber, and fertile soil for large-scale agriculture—are also among the world’s most threatened. In 2008, when Ecuador became the first country in the world to enshrine a revolutionary concept called the “rights of nature” in its constitution, conservationists gained perhaps their most powerful tool for protecting wild spaces. Today, that tool is being put to the test as advocates race to preserve habitats and the remarkable species they support.

20th of September 2024: Luozha Lazy Toad

Once again I come on Frog Friday to bring you the hottest new frogs, in this case one who was officially published about in December of 2023: the Luozha Lazy Toad (Scutiger luozhaensis). They were originally found in 2021 in Tibet at an alpine stream in a meadow [1].

They’re of a medium size, being around 5-7 cm long. They can be identified in part by small spine patches all over their body. Their forelimbs are considered rather long while their hindlimbs are rather short. Their eyes also look great, with a vertical pupil and a dark iris with irregular bronze spotting [1].

While they haven’t been evaluated by the IUCN, they are common in their habitat, which is the Luozha county in Tibet. Their habitat is within high altitudes, but extends beyond just streams to include ponds and moist scrub or forest floors near bodies of water. Their breeding season is up until June, as afterwards no mating calls have been recorded, however their tadpoles likely overwinter [1].

Their discovery provides support for the Paleo-Tibetan origin hypothesis [1], which supposes that a lot of biodiversity originally formed within the Paleo-Tibet (meaning species differentiated there), only to be further separated by the slopes of the Himalayas [2].

*points to a baby* A REPRODUCTION HAS OCCURRED

[reasonsforhope]

Pairing frogs and toads together might conjure memories of Arnold Lobel’s beloved characters — dressed to the nines in caramel coats and polyester — biking off toward adventure. 

But in the animal world, frogs and toads on nearly every continent are facing a much more harrowing adventure: a decades-long fight against a mysterious fungal virus that has afflicted over 500 amphibian species. 

Since the 1990s, scientists estimate that the chytridiomycosis disease caused by the fungal pathogen Bd (Batrachochytrium dendrobatidis) has led to the extinction of 90 amphibians. One of the lost species includes the Panamanian golden frog, which hasn’t been spotted in the wild since 2009. 

Fortunately, a new research study has finally pinpointed the virus that has been infecting fungal genomes for decades. 

“Bd is a generalist pathogen and is associated with the decline of over 500 amphibian species…here, we describe the discovery of a novel DNA mycovirus of Bd,” wrote Mark Yacoub — the lead author of the study and a microbiology doctoral student at the University of California, Riverside. 

In an interview with UC Riverside News, Yacoub said that he and microbiology professor Jason Stajich observed the viral genome while studying the broader population genetics of mycovirus (viruses of fungi). 

The discovery will undoubtedly have monumental impacts on future amphibian conservation efforts. This includes the possible launching of new research studies into fungal species strains, the practice of cloning and observing spores, and engineering a solution to the virus. 

But Yacoub cautioned that this is only the beginning. 

“We don’t know how the virus infects the fungus, how it gets into the cells,” Yacoub said. “If we’re going to engineer the virus to help amphibians, we need answers to questions like these.”

Still, as scientists strengthen conservation efforts to save frogs and toads (and salamanders too!) they also appear to be saving themselves. Yacoub pointed out several amphibian species around the world have begun exhibiting resistance to Bd. 

“Like with COVID, there is a slow buildup of immunity,” Yacoub explained. “We are hoping to assist nature in taking its course.”

Why are frogs and toads so important?

From the get go, every amphibian species plays an important role in their local ecosystem. Not only are they prey for a slew of animals like lizards, snakes, otters, birds, and more, but in an eat-or-be-eaten world, frogs and toads benefit the food chain by doing both. 

Even freshly hatched tadpoles — no bigger than a button — can reduce contamination in their surrounding pond water by nibbling on algae blooms. 

As they grow bigger (and leggier), amphibians snack on whatever insect comes their way, greatly reducing the population of harmful pests and making a considerable dent in the transmission malaria, dengue, and Zika fever by eating mosquito larvae. 

“Frogs control bad insects, crop pests, and mosquitoes,” Yacoub said. “If their populations all over the world collapse, it could be devastating.” 

Yacoub also pointed out that amphibians are the “canary in the coal mine of climate change,” because they are an indicator species. Frogs and toads have permeable skin, making them sensitive to changes in their environment, and they also rely on freshwater. 

When amphibians vanish from an ecosystem, it’s a symptom of greater environmental issues...

Herpetologist Maureen Donnelly echoed Yacoub’s sentiments in an interview with Phys Org, noting that when it comes to food chains, biodiversity, and environmental impact, the role of frogs and toads should not be overlooked. 

“Conservation must be a global team effort,” Donnelly said. “We are the stewards of the planet and are responsible for all living creatures.”
