Title Desiccation induced nitrate and ammonium uptake in the red alga Catenella repens (Rhodophyta, Gigartinales)
 
Creator Datta, Ramalakshmi

Description 458-460
Nitrate and
ammonium uptake rates were measured under laboratory conditions for the
intertidal mangrove alga C. repens when the thalli were desiccated to
0-60% and resubmerged. An enhancement in the nitrate and ammonium uptake

was seen in plants desiccated
up to 20-40%.These enhanced rates were 1.76 (for nitrate) and 1.42 (for
ammonium) times higher than the uptake rates of fully hydrated plants
(control). After desiccation, the enhancement in the nitrate uptake rates on
resubmergence lasted much longer than the increase in ammonium uptake. The
degree and duration of this enhancement in nitrate uptake due to desiccation
must be aiding the alga in the procurement of nitrogen.
