🦀 "Cuando el problema se convierte en negocio, hay resistencia a acabar con él".
Científicos cuestionan el "invasivorismo", el consumo de especies invasoras, como estrategia de gestión de invasiones biológicas. En muchos casos, perpetúan o agravan el problema.

If you can't beat 'em, eat 'em?
Really?
Our new opinion piece in @pnas.org defends that the so-called invasivorism is not an effective management strategy. In most cases, it is not even a strategy

“(...) Deciding which of the numerous existing management options to apply requires weighing up the social and ecological costs and benefits in a specific context"

To tackle biological invasions, we need to study people and ecosystems together.
Our recent paper shows how social–ecological networks can reveal introduction pathways, impacts, and better management strategies.

Excited to announce the imminent publication of the new Crayfishes Guide for Canada !
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

🔵 Aquaculture is one of the most important pathways for the introduction of non-native species.
Since 1950, one third of species used in aquaculture have been farmed outside of their native ranges.

Mara Torreblanca explained how the otter has learned to consume on the Atlantic blue crab, /Callinectes sapidus/, a truly dangerous prey, forced by the temporal scarcity of the red swamp crayfish, /Procambarus clarkii/.

Today, Mara Torreblanca successfully defended her MSc thesis on otter diet in the Río Cachón, and the role of the many, and colourful, invasive prey
At @pablodeolavide.upo.es , with @sergiobedmar.bsky.social and @oficialdegui.bsky.social
A really great work! (lucky us!)

Day 2 of the #GuardIAS meeting was all about our 11 case studies!
Great to see the nitty-gritty of using eDNA & drones for detection, modelling population spread, and launching new citizen science projects.
Also got a preview of upcoming online events from at @invasivesnet.bsky.social.
🌱 Más de 1.200 especies no nativas están establecidas en la Península, según un estudio en el que ha participado @ebdonana.bsky.social

Las plantas vasculares (Tracheophyta) y los insectos (Arthropoda) dominan entre las especies no nativas en Iberia. Asteraceae y Formicidae son las familias más frecuentes. Foto: Vespa velutina.

La mayoría de especies no nativas llegaron por escape de jardines, acuarios o cultivos, en especial plantas. Insectos y crustáceos se introdujeron como polizones o acompañantes involuntarios, reflejando el papel del transporte global. España y Portugal comparten patrones similares.
La mayoría de las especies provienen del Paleártico, pero también llegan desde América, África y Asia. El comercio y el clima explican esta mezcla de orígenes
Las introducciones se dispararon desde 1950, con picos en los años 70. Aunque los registros han bajado, las invasiones siguen activas y requieren vigilancia
Las #invasionesbiológicas avanzan en la Península Ibérica: más de 1200 especies no nativas ya están establecidas. Un estudio mapea rutas, orígenes y focos de invasión con la ayuda de datos de @gbif.org. ¿Cómo frenarlas antes de que sea tarde?

We have completed the 3rd year of our monitoring in Río Cachón (Zahara de los, Atunes, S Spain),a highly invaded and constantly changing small estuary.
16 surveys and +400 fyke nets, hundreds of otter scats, to just start learning how complex and fascinating the system is.

📝Non-Native Species in Aquaculture: Burgeoning Production and Environmental Sustainability Risks doi.org/10.1111/raq.... Finally out! 🥳@rosscuthbert.bsky.social @mkour.bsky.social
Non-native species have accounted for approximately one-third of global annual aquaculture production, with this proportion exceeding 35% nowadays. While offering economic opportunities and sustaining livelihoods, non-native production also pose significant environmental risks.
According to the proportion of species donated and received, Asia and North America were the primary donors of non-native species, while Europe and South America receive a large number of species. Asian species have been extensively translocated both inter- and intra-continentally for aquaculture
