Do cushions of Thylacospermum caespitosum ( Caryophyllaceae ) facilitate other plants under extreme altitude and dry conditions in the north-west Himalayas?
The results support the emerging theoretical prediction of restricted facilitative effects under extreme combinations of cold and dryness, integrating these ideas in the context of the ecology of cushion plants. This evidence suggests that cases of missing strong facilitation are likely to be found in other extreme alpine conditions.
There has been a significant reduction in bacteriologically confirmed MDR-TB cases. The increase in RMP monoresistance has important implications for treatment.
