Conversely, the non-migratory movements of song thrushes, either at wintering grounds or at stopovers, generate short dispersal distances (mostly < 1 km), very similar across plant species. Reason: differences in retention times among plant spp are not important when movements are not directional.

🧵 8/8 The mechanistic models of seed dispersal were developed in close collaboration with Juan M. Morales in Scotland and Spain.
This research was funded by the MIGRANTSEEDS project.
The paper was wonderfully led by @cabracho-estevanez.bsky.social as part of his PhD thesis.

🧵 7/n GPS tracking of birds involved numerous field campaigns between 2019 and 2023 in Cádiz (Spain), Helgoland (Germany), Falsterbo (Sweden), and Ventės Ragas (Lithuania). This was possible thanks to bird ringers and ringing stations (Vogelwarte Helgoland, Falsterbo Fågelstation and Ventės Ragas).

🧵 6/n But, due to their longer retention times, plant species with smaller seeds have a greater capacity to be dispersed by migratory flights and over longer distances. So, apart from fruiting phenology (doi.org/10.1038/s415...), seed size is a key trait that helps plants track rapid climate change.

🧵 5/n Our study reveals the ability of migrant frugivorous birds to (re)distribute plant species. Their role as long-distance seed dispersers may help explain past changes in plant distributions and the colonization of oceanic islands, and could be crucial for plants in fragmented landscapes.

🧵 4/n Song thrushes can disperse seeds over tens or even hundreds of km during their migration, depending on the plant species (maximum distances ranged from 58 km to 521 km). Conversely, seed dispersal distances mediated by non-migratory movements were typically shorter than 1 km.

🧵 3/n Here, we studied the seed dispersal capacity of the song thrush (Turdus philomelos) by tracking migratory movements across Europe and by combining this information with empirical data on fruit ingestion times, departure times, flight speed, and seed retention times in the birds' gut.

🧵 2/n The migration of frugivorous birds is one of the biological phenomena with the greatest potential to disperse the seeds of fleshy-fruited plants over long distances. But we did not know the distances over which frugivorous birds are able to disperse seeds during migration.

How far can frugivorous birds disperse seeds during migration?

Longer seed retention does not guarantee longer dispersal distances if animals exhibit a resident behaviour

Tiempos de retención de semillas más largos no garantizan mayores distancias de dispersión si los animales tienen un comportamiento residente

Spotless starling (Sturnus unicolor) released after being tagged with a GPS transmitter. We are studying the movements of these open-habitat frugivores to better understand their role as seed dispersers in anthropogenic landscapes.

Los cambios de uso en las salinas del Parque Natural Bahía de Cádiz y la dispersión de semillas por aves frugívoras están modificando poco a poco el paisaje de la marisma.

Acebuches, lentiscos y plantas exóticas como Opuntia dillenii colonizan y se expanden por los muros.

Este jueves Claudio defenderá su tesis doctoral sobre dispersión de semillas a larga distancia por aves frugívoras migratorias.

Si quieres saber cómo ha abordado este tema tan fascinante y desafiante, te esperamos a las 10:30 en la Sala Bolivar del Edificio Constitución 1812 (Cádiz) de la UCA.

Los gálbulos de cedro canario suponen el 95% de la dieta del mirlo capiblanco en biomasa (doi.org/10.3161/0001...).
En este ecosistema árido, el agua es tan importante como el alimento determinando la probabilidad y la intensidad del uso del espacio!

Todos estos movimientos estuvieron fuertemente ligados a la cobertura de cedros canarios (a) y a la zonas con puntos de agua cercanos (b), así como zonas con mayor pendiente (c) y (d) cobertura de arbustos de gran porte
