Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

open access: yesBoreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

Two LEAFY homologs ILFY1 and ILFY2 control reproductive and vegetative developments in Isoetes L.

open access: yesScientific Reports, 2017
LEAFY (LFY) is a plant-specific transcription factor, which is found in algae and all land plants. LFY homologs exert ancestral roles in regulating cell division and obtain novel functions to control floral identity. Isoetes L.
