Seasonal variation in essential oil yield and composition from naturalized thymus vulgaris L. in New Zealand
The seasonal variation in essential oil yield and composition from naturalized Thymus vulgaris L. in Central Otago, New Zealand, is reported. Essential oil yield (l/ha), from replicated, pilot-scale… Expand
Red leaf margins indicate increased polygodial content and function as visual signals to reduce herbivory in Pseudowintera colorata.
Red-pigmented leaf margins are common, but their functional significance is unknown. We hypothesized that red leaf margins reduce leaf herbivory by signalling to herbivorous insects the presence of… Expand
