The footprint of evolution in seed dispersal interactions


Mutually useful interactions between vegetation and frugivorous birds have advanced for at the least 80 million years (1). Now, greater than 70% of flowering vegetation depend on birds to disperse their seeds, and about 56% of chook households eat fruits as a part of their weight-reduction plan (2, 3). Crops typically have multiple seed disperser, and birds eat several types of fruits from completely different plant species, thus establishing a posh community of interactions. These networks can change significantly throughout house and time (4). Over brief time spans, seed-dispersal interactions are dynamic and alter in response to elements resembling competitors or abundance of the interacting associate (5, 6). Nevertheless, the consequences of evolutionary processes that happen over deep time will not be clear (7). On web page 733 of this difficulty, Burin et al. (8) recommend that evolutionary stability is related to the particular function of the chook species in seed-dispersal networks.
