Cyanobacterial-lichen soil crusts of San Nicolas Island
Proceedings: The Fourth California Islands Symposium: Update on the Status of Resources
Santa Barbara Museum of Natural History
Cyanobacterial-lichen soil crusts are a dominant feature on the soils of San Nicolas Island. These crusts can play many important roles in ecosystems in which they occur. These roles can include contribution of nitrogen to soil nitrogen pools, enhancement of element uptake in vascular plants, increase in vascular plant seedling establishment and survival, and stabilization of soil surfaces. Species composition of crusts on San Nicolas Island are discussed, along with the roles the crusts play in the different habitat types found on the island, and the effects of disturbance on the crusts, including successional sequences, nitrogenase activity, and recovery rates.
