Por si te perdistes las newsletters anteriores te pongo en contexto:
Me voy a Tailandia el viernes (chincha rabincha)
Quería buscar Danios, porque se supone que están en el sudeste asiático.
Miré un sitio serio de citas de especies de peces (Fish base) y Tailandia no salía entre los países donde se han visto Danios.
Me puse triste. (Bueno poco, que voy a ver muchas más cosas en Tailandia. Era para darle fuerza dramática al relato).
Pero, mirándolo más despacio, vi que daban un mapita.
Míralo. Los círculos verdes es donde hay danios y te he pintado de azul Tailandia:
Estamos rodeados.
¿De verdad que no hay? Ya no lo tengo tan claro.
Igual no ha habido ninguna exploradora lo suficientemente audaz para encontrarlo y reportarlo.
Así que buscaré. ¿Te imaginas que soy la primera? 😱
Di que no molaría.
Ahora observa un poco más. En la tabla y en el plano tienes dos tipos de círculos. El redondo y el que es una i. I significa introducido.
Es decir el ser humano, ha metido Danios donde no estaban originalmente.
El área natural, digamos, es más tendente a la India, pero en Japón, Sri Lanka, Filipinas… ahí ha sido introducido. He leído en otra fuente que por control de mosquitos.
Y si te fijas más también está en USA y Colombia. Eso está en otro continente. No toca que en esos países haya Danios. Pero si llegan ahí, están en unas condiciones que les molan de temperatura, tipo de agua etc… pues empiezan a reproducirse.
Y eso puede causar desastres ecológicos importantes.
En el proyecto:
hago muchísimo hincapié en este tema. No puedes soltar tus danios al río Segura. Tienen que estar en un acuario.
Hay mucha gente a la que le regalan una tortuguita de Florida, esas de mofletes naranjas, que un buen día piensa que estaría mejor en el río en libertad y la suelta al río de su pueblo.
Y como es una tortuga fuerte y se lo come todo desplaza a las especies autóctonas como el galápago leproso.
Así con un montón de bichos.
Ahora, estoy segura de que la posibilidad de que un niñ@ que haya hecho mi proyecto libere una especie que no toca a un hábitat que no es el suyo es muy pequeña. Es algo que siempre que visito un cole que ha hecho el proyecto pregunto y les queda clarísimo.
Un abrazo

In case you missed the previous newsletters I'll put you in context:
I'm going to Thailand on Friday
I wanted to look for Danios, because they are supposed to be in South East Asia.
I looked at a serious fish species dating site (Fish base) and Thailand was not listed as one of the countries where Danios have been seen.
I was saddened. (Well, a little, as I'm going to see a lot more in Thailand. It was to give dramatic force to the story).
But, looking at it more slowly, I saw that they gave a map.
Look at it above. The green circles are where there are danios and I've painted Thailand blue:
We are surrounded.
Are there really no danios? I'm not so sure anymore.
Maybe there hasn't been any explorer daring enough to find it and report it.
So I'll look. Can you imagine I'm the first? 😱
Say it wouldn't be cool.
Now watch some more. In the table and in the plan you have two types of circles. The round one and the one that is an i. I stands for introduced.
That is to say, the human being has put Danios where they were not originally.
The natural area, let's say, tends to be more towards India, but in Japan, Sri Lanka, the Philippines... there it has been introduced. I have read in another source that it was introduced for mosquito control.
And if you look more closely it's also in the USA and Colombia. That's on another continent. It doesn't mean that there are Danios in those countries. But if they get there, they are in conditions that suit them in terms of temperature, type of water, etc... they start to reproduce.
And that can cause major ecological disasters.
In the project The start of life, I put a lot of emphasis on this issue.
You can't release your danios in a local river (unless you are in India). They have to be in an aquarium.
There are many people who are given a Florida turtle, those with orange cheeks, who one day think that it would be better in the river in the wild and release it into the river in their village.
And as it is a strong turtle and eats everything, it displaces the native species such as the European pond turtle.
And so on with a lot of critters.
Now, I am sure that the chance of a child who has done my project releasing a species it doesn't touch into a habitat that is not its own is very small. It's something that I always ask when I visit a school that has done the project and it's very clear to them. It also has the not inconsiderable advantage that you can see Danios in embryonic stage without having to go to Bangladesh.
A big hug
