资源简介:
We estimated rates of DOC exudation by Macrocystis
pyrifera using short-term (2-4 hours) in situ incubations
of entire blades and portions of stipes in the kelp forest at Mohawk
Reef near Santa Barbara, California, USA
(34 o 23.660’ N,
119 o 43.800’ W). Incubations of blades were
conducted within 2 m of the sea surface at midday on eight dates
between October 2007 and August 2011 to investigate the effects of
blade growth stage, nutrient status (as indicated by C:N ratio
determined using an Exeter Analytical CE-440 CHN/O/S elemental
analyzer), epiphyte load, sea surface irradiance, and sea surface
temperature on rates of DOC release from intact blades.
