Threats

Intrinsic Vulnerability

Most oribatid mites are K-selected (Norton 1994) meaning they have stable populations with long generation times, low metabolic rates, slow development, low fertility, iteroparity, and adults are long-lived. They are also slow to disperse/recolonize due to their small size (0.3 - 2.1 cm per day; Lehmitz et al. 2012), which also means they cannot move out of harm's way during a disturbance event.
