Some scientists are skeptical whether seed dispersal syndromes actually exist because their parallel, pollination syndromes, are often disputed in scientific literature. Seed dispersal syndromes do not seem to have much disagreement among scientists. It is unclear whether this is due to lack of research or interest in seed dispersal syndromes, or that scientists agree with the idea of seed dispersal syndromes. It also may be that seed dispersal syndromes are harder to test because once seeds disperse they are difficult to collect and study. Jordano (1995) states that the evolution of fruit traits for seed dispersal success is only dependent on diameter. This is one scientist’s perspective but does not appear to be the common consensus among scientists. Colour and olfaction are other common seed dispersal syndromes tested and discussed in scientific literature. One limitation to seed dispersal syndromes mentioned is the limited definitions of syndrome characteristics such as odour or texture. It is possible that there has not been enough research to test these characteristics or they do not play a role in seed dispersal syndromes.
