Effect of passage through duck gut on germination of fennel pondweed seeds*
With 1 figure and 3 tables Abstract: Vertebrates are important seed dispersers for many plants. In addition to transport of seeds, ingestion often affects the proportion or rate of seed germination. We present one of the first studies comparing the effects of different waterbird species on the seeds...
