Do mites eat and run? A systematic review of feeding and dispersal strategies

Dispersal is an important process affecting the survival of organisms and the structure and dynamics of communities and ecosystems in space and time. It is a multiphase phenomenon influenced by many internal and external factors. Dispersal syndromes can be complicated, but they are vital to our knowledge of the biology of any organism. We analysed dispersal ability in mites (Acariformes and Parasitiformes), a highly diverse group of wingless arthropods, taking into consideration various modes of dispersal, feeding strategies, body size and the number of articles published for each species. Based on 174 articles summarized for this study, it appears that mites are opportunistic when it comes to dispersal, regardless of their feeding habits, and are often able to adopt several different strategies as needs arise. Moreover, we find a significant positive relationship between the amount of research effort that was put into studying a given species and the number of modes of dispersal that were described. The most salient conclusion to be drawn from this positive correlation is that additional studies are needed, especially on a broader set of mite taxa, until the aforementioned correlation is no longer demonstrably significant.
