Does artificial asymmetric warming reduce nectar yield in a Tibetan alpine species of Asteraceae?
The negative effect of asymmetric warming on nectar yields in S. nigrescens may be explained by a concomitant depletion of leaf non-structural carbohydrates. The results thus highlight a novel aspect of how climate change might affect plant-pollinator interactions and plant reproduction via induction of allocation shifts for plants growing in communities subject to asymmetric warming.
In view of lower sensitivity and accuracy rates for fine-needle aspiration biopsy, the routine use of frozen-section examination seems to be necessary especially in cases with highly suggestive clinical findings of malignancy.
