🙀Invasive species cause such diverse ecological impacts that we needed to broaden the lens used to classify their effects. Very happy with the collaborative and progressive nature of this work, integrating previous efforts and helping fill key gaps after years of worldwide effort!
Back in the field to continue our monitoring of the Rio Cachón (Zahara de los Atunes, S Spain).
This winter's huge floods have radically changed the estuary, forming a new mouth and adding some 200m of new estuary channel.
Many animals (and things!) were washed to the sea

Winner, Compact: Alpine Lookout by Andrea Michelutti ‘After years of waiting, I dived into the cold alpine Lake Cornino near my home in north-eastern Italy. Its clear waters rise from a spring, making it a gem among the mountains. Life is sparse, but I spotted a freshwater crayfish. It swam toward me until it was touching my wet lens. The composition I’d planned for years is built on the transition from green vegetation to deep-blue water, with mountain peaks framed in Snell’s window – a phenomenon by which an underwater viewer sees everything above the surface through a cone of light.’
[3/3] Andrea Michelutti photographie un lac alpin du nord-est italien, alimenté par une source et réputé pour la clarté de ses eaux. Depuis le fond, on distingue les sommets et le ciel, effet optique qui permet de voir simultanément sous l’eau et au-dessus.

1- la explotación tienes dos componentes (legal e ilegal) íntimamente relacionados
2- es necesario atajar el consumo (además de vedar la especie) para conservar la anguila
@pbustinduy.bsky.social , consumo puede hacer algo?

If you don't know Wanda's work- that's shocking! Because she's the best! Oh and edit- I didn't mean to say she was 'the first' to do author-illustrator/lettering combo but that she pushed that forward quite a lot. More on @Moonbow.books lnkd.in/gqqXz9R8 #wandagag #millionsofcats #newtypeface
Overall, a wonderful spring bloom
Tracks of Egyptian mongoose, Herpestes ichneumon, and otter, Lutra lutra
Iberian pond turtle, Mauremys leprosa
Iberian parsley frog, Pelodytes ibericus, tadpole
Male mummichog, Fundulus heteroclitus, had quite nice colour patterns
We also caught some European sea basses, Dicentrarchus labrax
What a beautiful fish
A come back
We had not seen marbled crab, Pachygrapsus marmoratus, in the Rio Cachón since 2022
Floods changed everything
We caught few blue crabs, Callinectes sapidus, and they seemed less agile (and less dangerous!) than usual (probably due to cold waters)
The floods had distributed red swamp crayfish, Procambarus clarkii, all along the estuary
This individual was living in the beach
In fact, all grey mullets were looking very nice
Chelon ramada
The new estuary also had new species. After 18 surveys we caught for the first time flathead grey mullets, Mugill cephalus
Such a beautiful and powerful animal

Huh. So is this the same species of parrot they were breeding at Paquime near the US-Mexico border and at Chaco???

Creo que coincidimos en la visión (también si le quitas lo fósil)
Pero la balanza que planteas me parece forzada, como si buscase adhesiones inquebrantables a cosas que vale la pena plantear y discutir
Cuando haces los cálculos para España, resulta que los datos USA se extrapolan bastante bien
Pero en lo segundo tienes toda la razón
Hola, Emilio
No tienes que convencerme de lo mucho que matan los gatos
Pero el gráfico es engañoso, porque la mortalidad no es igual de grave para cada especie
Los gatos en España matarán unos millones de gorriones al año. Pero unas decenas de alimoches muertos generan un impacto mucho mayor

La historia de los De Buen, la introducción de la gambusia y la (casi) erradicación de la malaria es tan redonda que da pena estropearla
Pero no parece que la invasión de ese pequeño pez fuese importante para el control de la enfermedad
