Ecological genetics in the North Atlantic: environmental gradients and adaptati...
Schmidt, P. S.; Serrão, Ester; Pearson, G. A.; Riginos, C.; Rawson, P. D.; Hilbish, T. J.; Brawley, S. H.; Trussell, G. C.; Carrington, E.The North Atlantic intertidal community provides a rich set of organismal and environmental material for the study of ecological genetics. Clearly defined environmental gradients exist at multiple spatial scales: there are broad latitudinal trends in temperature, meso-scale changes in salinity along estuaries, and smaller scale gradients in desiccation and temperature spanning the intertidal range. The geology ...
Control of gamete release in fucoid algae: sensing hydrodynamic conditions via ...
Pearson, G. A.; Serrão, Ester; Brawley, S. H.We investigated the environmental factors providing signals for gamete release in fucoid algae, with a particular focus on the inhibitory effect of water motion. The release of gametes by Fucus distichus occurred in still water under high light and was associated with the depletion of dissolved inorganic carbon (DIC) in tide pools isolated from the ocean during daytime low tides. Diurnal patterns of gamete rele...
