Arrozales del Delta del Ebro plagados de caracol manzana. Se trata de una especie exótica invasora que produce graves daños en los arrozales, siendo muy difícil de erradicar.
La introducción de especies foráneas puede producir graves daños ambientales, sociales y económicos.
We sampled the surface sediment (~50 cm) of the Albufera with a spear and extracted an almost perfect core (it's not right for me to say so, because I extracted it). You can see a very structured deposition. Can you guess what happened in the thicker top layer?

This was yesterday during the field trip for the course Impacts on the Aquatic Environment in the Master's Degree in Biodiversity: Conservation and Evolution, at the Faculty of Biology of the University of Valencia.

Totalmente cierto! Un jardín, un huerto o un parque (por eso son también tan importantes en las ciudades). Siempre voy fijándome! ☺️☺️

New paper out! Using sediment cores, we analyzed rotifer diapausing egg banks to track temporal variation in reproductive success. Populations with ⬆️ variation showed ⬇️ hatching fractions, supporting bet hedging.
If interested, you can find it here: doi.org/10.1093/plan...
Or ask me directly ;)
Gracias Juli! Leeré la reseña y el libro Sara García Alonso con mucho interés. Por cierto, el post y el título del libro me han recordado este otro que leí este verano y que me pareció una delicia 👇🏻

Rotifer habitats with shorter and less stable hydroperiods likely select for earlier (sex induced) diapause. Also, we detected trade-offs between traits related to leaving diapause that show the dilemma of spreading hatching among or within growing seasons.

Second stop: Delta de l'Ebre! Here, we spotted the invasive golden apple snail <Pomacea canaliculata> 🐌. Our project #BioScaling also explores how rice fields can act as gateways for non-native species introduction and establishment. 🌾 #InvasiveSpecies

We were just doing plant cover transects with first year Biology undergraduates but they were struck by the diversity of bugs that can play a role in pollination. There is nothing more mind-blowing than observing nature!!! Hooray for these young naturalists!

NEW PAPER, JUST OUT! 👀
Insects from the '70s and '80s were already collecting microplastic, decades before the term microplastic even existed. 🤯
A thread on the surprising history of this pollutant and the incredible insect larvae that helped us uncover it. 🐛
