Lichen community diversity on a remnant forest in south of Chaco region (Cordoba, Argentina)

The lichen community diversity in patches of Chaco forest -NE of Cordoba Province, Argentina was analyzed. Fifteen forest patches embedded in farmland areas were sampled. Size of the patch and exposure to the crops were registered. In each patch, ten trees (sample units) with epiphytic lichens were...
