Ecology and Evolution of Amazonian Fishes

Joined July 2019
We now have 273 gymnotiform electric fish species in South and Central America, including these from deep river channels (to 50 m) in the Western Amazon. How can we possibly learn all all this biodiversity? One species at a time. Image from: checklist.pensoft.net/articl…
Meet Eigenmannia macuxi from the Branco river in the Amazon Basin. This brings to 27 the number of valid species in the most species-rich genus of sternopygid electric fishes, including many cryptic and pseudo-cryptic species. researchgate.net/publication…

For context, the US income inequality over the century from 1910 - 2010. From the Guilded Age through the early 20th century crises and mid century rise of the middle class, to the election of 1980 and subsequent laws allowing the immense concentration of wealth we have today.
Inequality has been steadily rising in the US over the past half century. ourworldindata.org/grapher/e…

Since 1975, when the top marginal tax rate was reduced from 70% to 37%, $79 trillion in wealth has been redistributed from the bottom 90% to the top 1%, according to that bastion of socialism the RAND Corporation. Trickle down economics is a total scam.

Also known as the Kapok tree, or Ceiba pentandra, a canopy emergent which can grow up to over 200 ft (61 m).
🇧🇷🌳 Sumaúma, 🌳 sagrada que acumula tanta água a partir das suas raízes, que, quando tem em excesso, libera água e irriga várias outras espécies nas proximidades. 👉🏽 Vamos protegê-la do desmatamento,de madeireiras ilegais que insistem no desmatamento.

In southern Louisiana we enjoy sitting in the shade.
Louis Armstrong never lived on the equator, which is why he recommended walking on the sunny side of the street.

Is the world successfully "decarbonizing," as the infamous Gates climate memo implied last week? Well, it turns out the answer depends on how you define 'decarbonization,' and how you measure 'success'... Quick thread🧵
Sorry to see. This is an area known for tornados.

“Amazônia em Alerta” A repercussão do nosso artigo na Science segue no El País. As águas amazônicas atingiram 41 °Cdurante a seca extrema, sem qualquer refúgio térmico para peixes e mamíferos aquáticos. Isso ameaça não só a biodiversidade, mas também a principal fonte de proteína de milhões de pessoas na Amazônia. As mudanças climáticas já estão alterando o prato das famílias ribeirinhas. A ciência precisa ser ouvida, e com urgência.Leia mais em elpais.com/clima-y-medio-amb… #Amazônia #MudançasClimáticas #SegurançaAlimentar #Biodiversidade

What does all this mean for the world’s 8 billion people? The physical damage inflicted by global warming costs the global economy around $1.4 trillion a year, according to BloombergNEF.
