Emergency!!! Lonely heart looking for love: Female. Stocky build. Height of 2 – 3 inches.

That is a very soulful look. How could any female Sehuencas water frog resist it? Sadly, that’s the problem. They havn’t found any female Sehuencas water frogs yet.

It’s not for want of trying. Back in February 2018 worldwide interest was raised when scientists as the Cochabamba Natural History Museum (Bolivia) started a campaign to find a mate and raise funds for a search. ( I don’t know how I missed this story the first time. For long time readers, this is my frog story for this year.)  From a February 14, 2018 article by Anoop Menon for India.com,

Scientists are scouring for a mate for Romeo, who has been calling forth for mates for the last nine years now. But alas, a mate hasn’t been found in the rivers and streams of the Sehuencas water frog’s natural habitat so far. So scientists have decided to make a Match.com profile for the lovelorn frog, according to the BBC [British Broadcasting Corporation]. The effort hopes to raise awareness of the condition of the Sehuencas water frog and raise money to fund searches for the Sehuencas water frog in areas where they once thrived.

Romeo’s dating profile reads, “I’m a pretty simple guy. I tend to keep to myself and have the best nights just chilling at home, maybe binge-watching the waters around me. I do love food, though, and will throw a pair of pants on and get out of the house if there’s a worm or snail to be eaten!” His preference is for females between two to three inches tall and is okay with drinkers but not smokers. But honestly, at this point, he should be fine with just about anything.

All jokes aside, Romeo’s plight is an important one. The profile links to the campaign donation page that it is part of, with an aim of raising USD 15,000 to search for more Sehuencas water frogs. And Match.com is doing its part by matching all donations made from February 9 to today, Valentine’s Day.

Zoe Schlanger’s February 10, 2018 article for Quartz, in the context of Romeo’s (and the scientists’) quest, offers information about the ‘current state of amphibia’, Note: Links have been removed)

As the Earth faces what some experts call its “sixth mass extinction,” amphibians, like frogs, are among the most imperiled. Around half of amphibian species (which includes toads, salamanders, frogs, and newts) are reported to be in decline. A third are considered to be threatened with extinction.

Last year, 10,000 critically endangered “scrotum frogs” that lived in Lake Titicaca on the border between Bolivia and Peru died en masse. In the US, federal scientists say the overall amphibian population is shrinking in size by 3.8% every year. That trend has continued since the 1960s, due to a mix of climate change, pesticide applications, and diseases like infectious fungi which can quickly decimate populations.

Frogs seem to be especially vulnerable. Roughly 74% of frog species globally are in decline, and 80% of the frog species that live in India are threatened, a researcher recently told the Hindustan Times.

Hande ‘s February 12, 2018 article for CNN adds a few more details about Romeo and about the effort to save him,

Arturo Munoz [Arturo Muñoz Saravia] , founder of the Bolivian Amphibian Initiative and GWC [Global Wildlife Conservaation] associate conservation scientist, said, “When biologists collected Romeo 10 years ago, we knew the Sehuencas water frog, like other amphibians in Bolivia, was in trouble, but we had no idea we wouldn’t be able to find a single other individual in all this time.”

Romeo started to call for a mate about a year after he was brought into captivity and Munoz pointed out that those calls have slowed in the last few years.

“We don’t want him to lose hope, and we continue to remain hopeful that others are out there, so we can establish a conservation breeding program to save this species,” Munoz said.

Update

They raised almost $25,000 in funds to search for a female but there’s been no luck yet. Sehuencas water frogs live for about 15 years and Romeo has lived in the Cochabamba Natural History Museum for the last nine or 10 years. You do the arithmetic.

Apparently, Sehuencas water frogs were once found in both Ecuador and Bolivia. Today, there are only two regions of Bolivia (Cochabamba and Santa Cruz) where they are reputed to live. (There is more about the current search for a mate in a July 26, 2018 news item on phys.org.)The Sehuencas water frog Wikipedia entry has this to say (Note: Links have been removed),

While it is currently listed as vulnerable by the IUCN [International Union for Conservation of Nature], this is based on an assessment that has not been updated since 2004.[1] No individuals have been encountered in the wild since 2008.

You can find out more about Muñoz’s Bolivian Amphibian Initiative here. There don’t seem to be any Romeo updates on the website but they still seem to be gathering donations. Romeo’s dating profile is here.

Plea

One possibility occurred to me (and I imagine others), if there’s someone out there who has a female Sehuencas water frog in their aquarium at home, please consider saving the species. I’m certain a deal can be made.

Finally,. Good luck, Romeo!

Peruvian scientist Marino Morikawa nanoremediates wetlands

Peru’s El Cascajo Lake has undergone a successful nanotechology-enabled remediation technique developed by scientist Marino Morikawa and which he hopes can be used to clean up Lake Titicaca according to a July 6, 2016 news item on news.co.cr,

Peruvian scientist Marino Morikawa, who “revived” polluted wetlands in 15 days using nanotechnology, now plans to try to clean up Lake Titicaca and the Huacachina lagoon, an oasis in the middle of the desert.

El Cascajo, an ecosystem of roughly 50 hectares (123 acres) in Chancay district, located north of Lima, began its recovery in 2010 with two inventions that Morikawa came up with using his own resources and money.

The idea of restoring the wetlands came from a call from Morikawa’s father, who told the scientist that El Cascajo, where they used to go fishing when Marino was a child, “was in very bad condition,” Morikawa told EFE.

Marino Morikawa, who earned a degree in environmental science from Japan’s Tsukuba University, visited the wetlands and found a dump for sewage ringed by an illegal landfill where migratory birds fed.

The stinky swamp was covered by aquatic plants, Morikawa said.

The fifteen day timeline for the cleanup seems to be contradicted in this June 22, 2014 article by Rosana Pinheiro for Agencia Plano (a Latin American news portal) describes the situation at Lake El Cascajo and the nanotechnology in more detail,

Peruvian scientist Marino Morikawa created a cleanse system using nanobubbles to decontaminate lake El Cascajo, located at Chancay district, north of Lima, Peru’s capital. After nearly four years of the start of the project, 90% of the lake waters are recovered, and the place is now visited once again by at least 70 species of migratory birds.

The lake was once home to more than a thousand species of migratory birds in the 1990s. …

The [nanotechnology-enabled] treatment is done with tiny bubbles, the nanobubbles, a thousand times smaller than the ones we can see in a glass of soda. These bubbles attract bacteria and metals using static charge and then decompose, releasing free radicals which destroy viruses present in water. The process has been recognized by the Commission of Science, Technology and Innovation of the Peruvian Congress.

Biofilters were also deployed to ease the cleaning process of the water. Morikawa divided the wetland area with pieces of bamboo, creating sectors to order the withdrawal of the aquatic weeds.

… At the beginning, in December 2010, he worked alone, making daily visits to the region to develop the project. After some time, he started receiving help from friends, local population and local government.

A few months after the beginning of the treatment, it was possible to see that El Cascajo waters were more crystalline. However, it was only in January 2013 that “a miracle happened” as Morikawa says: Thousands of migratory birds returned to the lake and occupied about 70% of the area, forming a white cover around the water.

Whether this took fifteen days or several months seems less important than the remediation of the wetlands, Lake El Cascajo, the return of the birds, and a better functioning ecosystem. Let’s hope the same success can be enjoyed at Lake Titicaca.

There are more details in both pieces which I encourage you to read in their entirety.
