Urban waterfowl are important seed dispersers for native and alien plants

Researchers analyses the role of mallards and Canada geese in the dispersal of seeds of aquatic and terrestrial plants. This research reveals that, contrary to previously thought, plants that do not have long-distance dispersal mechanisms can reach other habitats via waterfowl.

Las especies exóticas presentan una ventaja competitiva durante la dispersión de semillas que realizan las aves acuáticas por endozoocoria

This new study underlines the important role of seed traits in the endozoochory potential of alien and native plant species, notably through their influence on retention time and germination.

Plant-animal interactions in a scenario of rapid population expansion of a Mediterranean juniper

• Researchers at the Doñana Biological Station have analyzed which species have an essential role in the seed dispersal of Phoenicean juniper in the Doñana National Park.

Gulls can disperse seeds from native and alien plants between urban urban green areas

A study leaded by researchers from the Doñana Biological Station (EBD-CSIC) and the Institut de Ciències del Mar (ICM-CSIC) estimated the seeds dispersed and beyond Barcelona based on the movement of gulls monitored by GPS telemetry and seeds detected in their diet.
Modelling shows that around 30% of the seeds (including native plants but also alien species) were dispersed by gulls within green urban areas, concentrated in two main hotspots (Ciutadella Park and Montjuic), with important...

Different waterfowl species eat (and disperse) different seeds, depending on where they feed

A study led by the Doñana Biological Station (EBD-CSIC) found that the first step in seed dispersal by waterfowl – seed ingestion – depends on seed availability in the waterfowl foraging habitats. Researchers found that the main gradient found to determine such interactions is related to soil moisture, in line with differences between waterfowl groups in their microhabitat preferences along the land-water continuum
