American Green Tree Frog: Naturally found in the Southeastern United States, they prefer swamps and densely foliaged lakesides as habitats. Certain coastal populations, however, have developed a tolerance to moderate salinity in water thanks to different processes that regulate osmosis. Males form large choruses during mating season, and as a result are forced to modify their calls in frequency and duration to stand out from the others and draw attention from females. In some areas, they even compete with other species such as the invasive Osteopilus septentrionalis and modify their call to be more clearly heard. Females prefer lower-frequency calls, so if a male notices that his is distinctly higher-frequency than others in the area, he may forego calling altogether and attempt to ambush a female instead.

Purple Harlequin Toad: Native to French Guiana, it was found to likely belong to the Guiana Shield clade of harlequin toads through genetic testing done in 2020. Different populations separated by location vary significantly in size, with females from the Sophie region being smaller than males – contrary to all other populations of this species. Unfortunately, they are threatened by local logging and the chytrid fungus.

IT WAS LATE ON JULY 16, 1957, and Charles M. Bogert was in a recording booth in Highland County, Florida, with a pair of singers who wouldn’t sing. The burgeoning producer, who had left a busy life in New York to chase talent in the Sunshine State, had heard the two perform live that very evening, in a chorus of hundreds. He had plucked them from the crowd, and thenushered them out of the swampy night and into this soundproofed room. But his would-be stars—out of their element, lacking inspiration—were silent. So Bogert took out a pair of headphones and played them a recording of their own voices from earlier, amid the chorus. Instantly they began an unrestrained duet: BOOP! BOOP! BOOP — WAMP — BOOP — WAMP — BOOP — WAMP! The booper here is a barking treefrog (Hyla gratiosa), while the wamper is a hybrid frog, thought to be the offspring of a barking and a green treefrog (Hyla cinerea). Theirs is a standout performance on Sounds of North American Frogs, originally released on Smithsonian Folkways Recordings in 1958, and re-released at the end of 2023 by the same label...

It's a received wisdom that amphibians are intolerant of salinity in their water. With the usual caveat that Rana (or Fejervarya) cancrivora, a superficially ordinary Rana-like frog from Asia, is 'the only marine amphibian' and is presented as almost a miracle of nature. In fact, prehistoric amphibians were preserved in saltwater environments, and a few species of salamanders and frogs are tolerant of mildly brackish conditions.

One study investigated the salinity tolerances of tadpoles, belonging to a few species of North American frogs. All of the species investigated had near-perfect rates of survival at 5 parts per thousand of salinity. Where estuaries are of such a low salinity, it is clearly the freshwater components of estuarine biota that predominate. Nonetheless the salinity is elevated sufficiently at only 5 ppt, to qualify such water as brackish. The tadpoles of all the species suffered and died at higher percentages of salinity.

Thus it can only be remarkable when amphibians survive, and thrive, at higher salinities than 5 ppt. A large meta-analysis of amphibian salt tolerance, revealed that the majority of amphibian occurrences in brackish environments, predictably involved low salinities of about 5 ppt or below. Of the others, most involve salinities up to about 10 ppt. For contrast, seawater has a salinity of 33-38 ppt, and is usually communicated as 35 ppt, as though it were the same everywhere.

A salinity of 10 ppt is still at the low end of brackish salinities, below a specific gravity reading of 1.01. Therefore it is below the salinity expected to be maintained I a standard mangrove tank. A salinity of merely 5 ppt, is below 1.004. The mangrove associated R. cancrivora, is however able to complete it's life cycle, where the specific gravity would be 1.02.

It is also more significant when aquatic life stages are tolerant of saltwater, because amphibious, terrestrially motile animals may move to find freshwater. A number of species of amphibian adults, such as toads and mole salamanders, have been recorded in the field, in and around waters more saline than their proven or probable physiological tolerance.

Rana cancrivora are observed in the field to be at least temporarily present in waters with full marine salinity. Tadpoles of this species tolerate this, but the adults seem to have an upper limit of tolerance that is lower than their tadpole stages, at 28 ppt. Other amphibians with a fairly good physiological tolerance of salinity, seem limited to water where it is no more brackish, than 10 ppt or close readings.

These include the American bullfrog (Rana catesbiana), green treefrog (Hyla cinerea), Cuban treefrog (Osteopilus septentrionalis), yellow-bellied toads (Bombina variegata), common platanna (Xenopus laevis), and tiger salamander (Ambystoma tigrinum). Few amphibians tolerate higher than 10 ppt.

Adult cane toads (Rhinella marinus) live around waters with a salinity close to 15 ppt, although its life cycle is known to be impaired at salinities as low as 8 ppt, and 12 ppt is lethal to their tadpoles. Thus R. marinus, although they forage in coastal areas where the salinity is higher, are really among those amphibians bound to lower salinities of around 5 ppt or lower.

Which is to say, the aquatic life stages of an amphibian with amphibious or terrestrial adults, may be essentially a freshwater element that is present in certain estuarine environments. Some snakes and turtles similarly frequent mangroves and saltmarsh habitats, but require environmental freshwater, for example, moving to freshwater in order to drink, but feeding in brackish water.

This is the hybridity of the estuarine biota, with its marine and freshwater components, and also the bivalence of most amphibian life cycles, being able to breed in one environment, even microenvironment, whilst exploiting elsewhere. Typical amphibian life cycles are not inferior to those of reptiles and mammals, or the amphibians would not be so ubiquitous.

Which does in fact raise the question, of why there aren't any truly marine frog species. R. cancrivora and at least two other ranids, demonstrate that amphibians can actually evolve physiological tolerance to elevated natural salinities. Although this seems more common in some clades than in others. Asking the question is like asking why certain successful fish clades have remained essentially freshwater animals, such as cyprinids, loaches, tetras, and for the most part, catfishes.

Surely more than one factor is responsible, and possible explanations won't be mutually exclusive, when it comes to explaining why or why not. But competitive exclusion by clades that are established and dominant in saltwater environments, is a limit upon the range of niches, that are available for colonization, by intrusive pioneers moving down from upriver.

Adult frogs do not do very well in fast flowing waters, so they are unlikely to do very well where the tide is powerful. Some anurans have specialized tadpoles, bearing derived lifestyles and morphologies, that are appropriate to habitats such as fast flowing streams. But in such environments, fish competitors are relatively few. In the sea, frog tadpoles without mobile, paired hydrofoils, would need to compete against fishes with them, and other successful competitors.

First i must apologize I have a tendency to forget that tumblr - even when we're all 'on' - is not live interaction and additionally you can't actually read my mind 😅

This was in reaction to seeing your ... delightful?? .. new frog. In such a state. And I got nervous 😋🦀💖

Annon... I´m gonna cry... I love you♡♡♡ you´re making me do happy jumps♡

And I understand fully what you mean about "reading minds" if you can call it that, we´re all there at times!

I hope this is you trying to get me to talk about my wonderful frog Kaj because that´s what I´m gonna do know XD

-

This is Kaj - named after my second favorite show as a child - he´s 25 cm long, and he´s a treefrog, there didn´t stand which one but my best guess is a red eyed tree frog, he just doesn't have the blue stripes, he could also be a Agalychnis moreletii (Morelet's tree frog) but he doesn't have black eyes and Morelet´s are known for their black eyes (a nickname of theirs is black eyed frog).

He could also be an American green tree frog, but his feet are a bit too pigmented, and back a bit to light for that, although the eyes would match there.

Actually he´s a woman as he has an ovary and oviduct (the blue stuff you can see below his urostyle) but I didn´t know that until I unpacked him, where I already had named him

Going with the idea he´s a Morelet (as that´s what he looks most like) he would be around 60mm (f-54 m-60/64)

Red eyed tree frog gets around 6/7 cm (f-7,5 m-5)

All in conclusion he´s a tree frog. Which kind of one? Karl.

And no, the crabs need not fear, he´s much too small to be of any danger in the wild, and my Kaj is made of plastic so he doesn't really jump or eat, unfortunately.

Although some crabs might want to watch out for the Goliath frog... (world's biggest frog at around 32 cm and 3.3 kilograms)

Video description: Chart showing audio clips of various American frogs with months labeled at the top. As the play bar moves through the months, the frog calls active at those months play.

First are Wood Frog, Boreal Chorus Frog, and Spring Peeper. Northern Leopard Frog joins almost immediately. American Toad and Gray Treefrog join together. Wood Frog then ends, followed by Boreal Chorus Frog and Spring Peeper. Green Frog enters around the time Boreal Chorus Frog and Spring Peeper end. Shortly thereafter, American Bullfrog enters. Northern Leopard Frog ends, then American Toad and Gray Treefrog end together, then the last two continue together until Green Frog cuts off shortly before American Bullfrog.

This is an American Green Treefrog who hangs out on my deck.

[exocynraku]

Very excited you like my frogo. There are ten in total. We had a huge rain come in that lasted for two days and so they were gone, hunting and probably enjoying the nice weather. I've been waiting for them to return and now they are back! We have two that hang out on one of our hummingbird feeder. They are Gray treefrogs. Sorry- I'm training to be a herpetologist so... I know things pfft. I'll try not to bore you with that stuff. I have called the bigger one Nectar and the little one my grandmama named Nancy. We have seven little American green treefrogs and they doesn't have names but we have been lovingly been calling them days of the week. Then the last two are Shelly and Shelby. They stay on the shell decoration. They are Cope's green treefrogs. Thank you for letting me talk about my frogs. I'll stop boring you now ^^.

WOWOWOWOW!!! SOOO MANY!!!! so so so cool!! i love the pic where theyre all of the window LOL thats funny

Mural at infant school in Brazil - crowdfunding campaign

https://youtu.be/OhFp7ym5bIc

Original campaign: https://chuffed.org/project/infant-school-mural-brazil

What and where

We are painting an 85 metre mural at João Batista Cardoso infant school in São Luiz do Paraitinga, Brazil with the participation of the children, parents and teachers.

The mural will transform the wall into bright, colourful and engaging space for the whole community to enjoy, especially the children as they walk to and from school.

Why

The infant school takes approximately 180 children from 3-6 years old and is compulsory as the first stage of schooling in Brazil. The school provides a wonderful space for young children to play and learn but as part of a small rural town it lacks the funds to spend on anything other than the normal day-to-day running costs of the school. For this reason we are using crowdfunding and asking you to help us realise the project.

We strongly believe that participatory art projects bring people together in a creative, constructive and positive action that benefits both the individual participating and their wider community. Mural projects nurture and inspire creativity in children and adults alike and can boost morale, community cohesion and create a sense of pride and ownership over a public space.

How

Our community artist and project leader Andy will organise and implement the painting in conjunction with the director, teachers and parents of the school. Andy is an experienced community artist and has spent the last five years working in Brazil running various participatory art projects for children and young people with different charities and NGOs.¹

We will run scheduled sessions with the different classes for the children to participate in the painting as well as inviting and encouraging parents to participate as well.

Design

The design depicts many of the animals that are native to this region of Brazil and also the Paraitinga river which runs by the side of the school and from which the town gets its name.

The design of the mural is simple and geometric, this creates an impactful visual style whilst at the same time allowing for everyone to take part in painting as the design can be ‘painted by numbers’.

Mural plan to scale:

Details of each animal:

Capivara / Capybara – Hydrochoerus hydrochaeris

Corujinha-do-mato / Tropical screech-owl – Megascops choliba

Borboleta 88 / Cramer’s eighty-eight butterfly – Diaethria clymena

Bugio-ruivo / Brown howler monkey – Alouatta guariba

Jararacuçu / Jararacussu – Bothrops jararacussu

Tucano-de-bico-verde / Green-billed toucan – Ramphastos dicolorus

Preguiça-de-garganta-marrom / Brown-throated three-toed sloth - Bradypus variegatus

Beija-flor-de-orelha-violeta / White-vented violetear - Colibri serrirostris

Anta-brasileira / South American tapir - Tapirus terrestris

Saúva-limão / Leafcutter ant - Atta sexdens

Tatu-galinha / Nine-banded armadillo - Dasypus novemcinctus

Onça-pintada / Jaguar - Panthera onca

Periquito rico / Plain parakeet - Brotogeris tirica

Macaco-prego / Black capuchin - Sapajus nigritus

Rã-flautinha / Lutz's treefrog - Aplastodiscus albosignatus

Morcego-beija-flor / Geoffroy's tailless bat - Anoura Geoffroyi

Jacutinga / Black-fronted piping guan - Pipile jacutinga

Quati-de-cauda-anelada / South American coati - Nasua nasua

When

We have already painted around 20% of the space beginning with the water pattern which included the participation of the school children and we believe the project will realistically take five months to finish.

This timeline is an estimate that can change depending on various factors. It also does not just reflect the time it will take to paint the mural but the time it will take to complete the project as a whole. This includes the other preparation work necessary such as: finalising the design and colour choices inline with paint available, preparing the large stencils, transferring the design onto the wall and organising participatory workshops with the school children inline with the school's timetable.

Objectives

To complete the painting of the mural through the participation of parents, children and local community members.

To transform the space, creating a sense of ownership, pride and community.

To strengthen the ties between the families and the school.

To run further sessions with each class so that every child in the school makes their mark on the mural.

Funding

Until this point our community artist has given his time voluntarily to work on the project and we have been able to cover the cost of the paint and materials through fundraising events at the school. But with the scale of the mural and the time it will take to complete it this funding will to allow him to support himself whilst he completely dedicate his time to running the project with the school over the next five months.

We are looking for your help to raise £1000 to be able to fully realise the mural and achieve our objectives for the project.

This funding amount is based on the minimum monthly wage in Brazil which for 2019 is R$998.²

The average GBP-BRL exchange rate for the last 12 months has been 4.989.³

This equates to £200.04 per month, so a projected timeline of 5 months therefore gives a total of £1000.20
