Other claims from this paper (8)

Intervention effect Covered developing buds did not atrophy.

Intervention effect Covered bracts still had reduced weight at 49 days.
Intervention effect Uncovered buds fixed about forty times more labelled carbon dioxide at 28 days.
Intervention effect Covered and uncovered buds had the same sink intensity and relative specific activity.

Intervention effect Active pollinators did not visit dry communities at all.
Intervention effect Seed and flower weight of T. pratense decreased in flooded and dry communities.
Mechanism Negative effects of wetness and temporary flooding on floral resources were mostly caused by a decrease of insect-pollinated herbaceous species.
