Los científicos advierten contra la falsa creencia de que los árboles y otras plantas que crecen en los cauces compliquen la situación en caso de grandes avenidas de agua. “En la dana de Valencia se ha demostrado que los amontonamientos han sido de coches” elpais.com/clima-y-medio-amb…
El error de eliminar árboles y vegetación de ríos y barrancos ante el riesgo de inundación

El error de eliminar árboles y vegetación de ríos y barrancos ante el riesgo de inundación

Existe una creencia de que los cauces ‘limpios’ de plantas previenen las riadas, pero el efecto es el contrario: la velocidad del agua aumenta y provoca una mayor devastación en caso de avenidas

Un niño de una familia con estrés económico que a los 7 años tiene un rendimiento cognitivo alto, a los 18 ya lo tiene más bajo que un niño de familia más favorecida que partió de un CI medio. La genética se ve sobrepasada por un ambiente desfavorable. jstor.org/stable/43965555

Por esto no puedes dejar los cauces de los ríos como un lavabo. Porque el agua corre a gran velocidad y ESE es el problema. Que no es igual que te impacte a 30 km/h que a 90 una masa de agua descomunal.

Finalmente, encontramos uma abundância extremamente baixa de tubarões tanto em #SãoTomé como no #Príncipe (0,05 tubarões por hora), muito menor do que outras ilhas oceânicas do Atlântico! (8/9)

To fill the lack of ecological data in the archipelago, we deployed 400+ benthic #BRUVS, aiming to: 1) Characterise fish species composition in #SãoTomé and #Príncipe 2) Understand the effect of environmental variables relevant for marine planning on fish communities. (4/9)

BRUVS sitting in the bottom while recording. BRUVS were composed of a pyramid-shaped PVC frame, with the camera in the centre of the frame and an arm holding a bait cage. The frame was weighted using diving weights to keep them in the bottom

Finally, we found an extremely low abundance of #sharks in both #SãoTomé and #Príncipe (0.05 sharks per hour), much lower than other Atlantic oceanic islands! (8/9)
