Endozoochorus dispersal of aquatic plants: does seed gut passage affect plant perfomance?
The ingestion of seeds by vertebrates can affect the germinability and/or germination rate of seeds. It is, however, unclear if an earlier germination as a result of ingestion affects later plant performance. For sago pondweed, Potamogeton pectinatus, the effects of seed ingestion by ducks on both g...

The ingestion of seeds by vertebrates can affect the germinability and/or germination rate of seeds.
