It is estimated that over half of all species on the earth are parasitic at some stage during their life, which makes parasitism the most common lifestyle on earth. Parasites are integrated into almost every living system and recent estimates suggest parasites, and other symbiotic species, are declining at a faster rate than their vertebrate and invertebrate hosts. Given the diversity of parasites and the fact that they can cause disease and serve as a food source, it is essential to consider the role of parasite communities in wildlife conservation and ecosystem dynamics.
