Abstract:
Abstract Ectocarpene, (+)-(6S)-(1Z-butenyl)-2,5-cycloheptadiene, is the mating pherom one of the three distantly related seaweeds Ectocarpus siliculosus, Sphacelaria rigidula and Adenocystis utricularis. Analogu es of this pheromone, dif­fering in position and π-electron density of the double bond in the C4-side chain, were synthesized and assayed for biological activity. The results suggest, that the fundamen­tal molecular recognition process is conservative in all species, while receptor dynamics and -topologies have been modified by individual developments and expressions dur­ing plant phyl

Abstract:
Water availability and low temperatures are believed to be the main ecological limits for continental Antarctic lichens. Lichen growth may also be limited by nitrogen availability. Thallus nitrogen content of two dominant Antarctic macro lichens decreases significantly at the onset of the summer snow melt, but the causes are unknown. Over the past 40 years precipitation rates have increased in the Windmill Islands region of continental Antarctica. An increase in snow fall may result in lichens being wet for longer periods during the summer, which may result in an increase in photosynthetic a
