Un año más escuchando tantas historias inspiradoras en nuestra provincia, en la XI Jornada de Historia Natural de la SGHN. Especialmente emotivo por ser en una de las ciudades más importantes para mí.

Spatially 🗺️, these species use different parts of Cadiz Bay so plastic is transported to various regions of the natural area.

Temporal ⌛ variation is linked to differences in migratory behavior.

All this complicates the implementation of effective management strategies.

However, we also found that l.black-backed gulls transported more plastics overall due to their larger numbers during wintering and migration.
In total, the 3 spp. reached 531kg. of plastic in 2022.

Notably, we also found spatiotemporal variation in plastic transport

The three species involved are white storks, yellow-legged gulls and lesser black-backed gulls. All of them use the Cadiz Bay and adjacent landfills.

We found that storks transported more ⬆️ plastic mass per cápita by pellets to the wetlands probably due to their bigger size.

Landfills 🗑️ have become a reliable source of food 🍔 for some species and have even altered their migratory behavior 🧳✈️.
However, these open-air landfills also contain pollutants ☠️, including plastics. These contaminats do affect the birds, but their impact might be even worse...

Gracias amigo por esperarme cada día al volver de clase, por enseñarme que la vida es mucho más bonita que todo lo que nos han contado. Gracias por ser el único cuerdo en un mundo de locos.

6/ PRELIMINARY results show that around 500kg were estimated in one year
LF deposited more plastics due to their bigger populations.
This plastic biovectored followed the migratory pattern of the 3spp. As they use different regions of Cadiz Bay, mostly all the area suffer this transport.
April 3, 2025 at 8:32 AM
5/ Plastic was present in 80% of LM, 95% LF and 97% CC pellets. CC pellets were bigger and had similar plastic %. CC & LF had more N of particles than LM.
🥇We conclude that storks are more important vector per cápita than gulls.
But what if we include also populations??? Let’s see model results:
April 3, 2025 at 8:32 AM
4/ Model ⏰: We simulated that each individual estimated in the Cadiz Bay would egest 1 pellet with a random ⚖️ from those we 🔬.
We simulated it 10000 times to have ⬇️⬆️ ranges.
We then had a value of plastic transported for each day.
April 3, 2025 at 8:32 AM
3/ We followed by 🛰️ data, the movement of several individuals in the region, identify the sources of plastic and studied the daily wetlands-landfills travels
We censed birds in close dumps in 2022 and estimated with LOESS the number of individuals that roosted in the Cadiz Bay each day in 2022
April 3, 2025 at 8:31 AM
2/ Our study was performed in the SW of Spain, starred by three waterbird species: C. ciconia (CC), L. michahellis (LM) and L. fuscus (LF).
We sampled pellets from Cadiz Bay and separated their plastic content over 0.5mm. We took their ⚖️ and N particles.
😱 We also took some photos as this one:

1/🧵 One of the main drivers of 🌍 change is pollution
Birds foraging in landfills eats #plastics that egest in natural areas by pellets in a process known as biovectoring
We’re at the #BOU2025 presenting how we compare and quantify the biovector role of some aquatic species towards a natural area

Finally, water in the marsh. It took its time but what an image... Between rays of light and heavy showers, the rainbow appears, flamingos and avocets dance, kestrels fly over a new sea, terns arrive from a long journey, deer splash trying to escape from water.
