Living in Vulcan's forge: Algal adaptation to stressful geothermal ponds on Vulcano Island (southern Italy) as a result of pre‐selective mutationsPhycological Research - Tập 57 Số 2 - Trang 111-117 - 2009

SUMMARYFour species of eukaryotic algae proliferate in the sulfureous, acidic
(pH 3.1) water of the largest geothermal pond on Vulcano Island (southern
Italy). Consequently, this pond constitutes a natural laboratory for analysis of
adaptation by phytoplankters to extremely stressful conditions. To distinguish
between the pre‐selective or post‐selective origin of adaptation processes
allowing the ... hiện toàn bộ
The induction of reproductive cell formation of Ulva pertusa Kjellman (Ulvales, Ulvophyceae)Phycological Research - Tập 46 Số 3 - Trang 199-203 - 1998
Masanori Hiraoka, Sachito Enomoto
SUMMARYSynchronous zooid formation in Ulva pertusa Kjellman was induced in
excised disks maintained in sterilized seawater at 20°C, 12:12 h L:D cycle and
fluorescent light at 100 μmol photons m 2s 1. Zooids were reieased from mature
disk tissue on the morning of the second or the third day after excision. The
degree of zooid formation was found to be dependent on disk size and the region
of the mo... hiện toàn bộ
