Angiosperm seeds lacking external flesh can be adapted for endozoochory

It is often assumed that only plants with a fleshy fruit disperse inside vertebrate guts, i.e. by “endozoochory”. However, only 8% of European angiosperms have a fleshy fruit, and endozoochory of other plants by herbivorous or granivorous birds and mammals is widespread in nature. Many terrestrial and aquatic plants disperse via endozoochory by migratory waterbirds, providing long-dispersal dispersal.

Fish eggs can be dispersed by waterfowl

Researchers have found that eggs of two fish species can survive passage through the digestive tract of waterfowl after being swallowed, and this finding may help explain the long-standing mystery of how some species of fish colonize isolated lakes and ponds.

European Corvids disperse plants from 42 families by endozoochory

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...

Waterbirds can disperse whole plants inside their guts

It is well known that some plants and plant fragments can become attached to the feathers of ducks and other waterbirds and be transported short distances. An increasing diversity of plant seeds have also been shown to survive gut passage and to be able to disperse longer distances inside migratory birds. For the first time, this paper shows that entire flowering plants can be dispersed on the inside.

Long-distance dispersal by migratory waterbirds

Modern literature on plant dispersal by birds focuses mainly on the importance of frugivory and scatter-hoarding, yet recent studies show that endozoochory by migratory waterbirds is an important mechanism of long-distance dispersal for a broad range of plants. Nevertheless, there is a lack of empirical field studies that identify the plants dispersed by waterbirds in a comprehensive manner. In particular, so far there are no detailed studies of the level of spatial variation in the plant...
