- Description
- Many plants exploit the ability of animals to move in order to disperse their pollen and seeds. Despite the growing understanding of the role animals play in the reproductive lives of plants, there are few examples of amphibians contributing to these processes. We report on an Australian tree frog, Litoria fallax, interacting with and likely moving seeds of the broad-leaved cumbungi, Typha orientalis, over short distances via external transport. Field observations revealed both juvenile and adult L. fallax individuals carrying typha seeds, which were adhered to the skin on the feet, legs, belly and dorsum. Approximately 30% of observed frogs were found to be carrying 1–14 seeds at a time. The small size and specialised fibre tufts of typha seeds, which enable them to be primarily dispersed by wind, also make them susceptible to being unintentionally picked up and transported by L. fallax as they move through aquatic environments. The moist surfaces of frogs, coupled with their presence in freshwater systems that can be dominated by typha, create favourable conditions for seed attachment. These findings highlight a previously unknown interaction between an amphibian and a plant that enables seed dispersal, supporting the need for further exploration into unexpected plant vectors.
