• 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.

A study led by the Doñana Biological Station (EBD-CSIC) found that fruit-eating birds (frugivorous) in Doñana have experienced negative changes in the last 40 years: a decrease in their abundance, a lower fat reserve, and advances in their migratory timing.
? This could be due to vegetation shifts and increasing temperatures associated with climate change. Changes in the timing of migratory birds’ arrivals and departures can lead to a lack of synchronization between birds and fruit...

Members of the crow family (Corvidae) are known to disperse seeds by frugivory or by scatter hoarding, but are rarely recognized as vectors of plants lacking a fleshy fruit, or a large nut. A century ago, S.A. Heintze carried out extensive field studies of seed dispersal by 11 species of European Corvidae, especially Magpies Pica pica and Hooded Crows Corvus cornix. His work was published in Swedish and has been overlooked until now, and suggests that contemporary views about seed dispersal...
