Fruit-eating increases biodiversity.

Fruit-eating increases biodiversity.By dispersing the seeds of plants, fruit-eating animals contribute to the possibility of increased plant speciation and thus biodiversity, investigators have discovered. These are the findings of a new study led by Renske E. Onstein and W. Daniel Kissling, researchers at the University of Amsterdam's Institute for Biodiversity and Ecosystem Dynamics (IBED). The results were published in the journal Nature Ecology & Evolution. Tropical rain forests are the supermarkets for fleshy fruits: more than 70% of woody, tropical plant species have fleshy fruits and rely on fruit-eating animals such as chimpanzees, elephants or hornbills for their seed dispersal. By dispersing the seeds of plants over large distances, these animals contribute to the possibility of plant speciation. The international team of researchers from the Netherlands, UK, France, Sweden and Denmark investigated over 2000 palm species with fleshy fruits (such as the date palm) to understand how the ecology of species, their distribution, and the interaction with potential fruit-eating animals may have affected their past speciation.
