Title:SBC LTER: Reef: Surge uptake capability in Macrocystis pyrifera in response to pulses of three different forms of nitrogen
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data describes the capacity of the giant kelp, Macrocystis pyrifera to exhibit surge uptake of three different forms of nitrogen in whole-blade incubation experiments done in spring and summer 2019. The data is contained in 2 tables: 1) uptake rates of 15N labeled nitrate, ammonium, and urea by blades exposed to pulses of nitrogen for periods lasting 1, 5, 15 and 45 min, 2) uptake rates of 15N labeled nitrate, ammonium, and urea for specific time intervals of pulsed nitrogen (e.g., 0-1 min, 1-5 min, 5-15 min and 15-45 min).

Methods and protocols used in the collection of this data package
Description:

The Macrocystis pyrifera, is a foundation species for one of the most diverse ecosystems on Earth. Its productivity is affected by the availability and potential fluctuations of nutrients such as nitrogen. The Santa Barbara Coastal Long Term Ecological Research program has been studying the physiological capacity of M. pyrifera for surge uptake as a mechanism to enhance nitrogen assimilation during seasons when nitrate is depleted. This study uses laboratory incubation experiments to examine this phenomenon for three common forms of nitrogen, nitrate, ammonium, and urea, using whole kelp blades collected from the Santa Barbara Channel, a region where ambient nitrate concentrations average < 1 μmol L-1 during summer and autumn, and the pulsed delivery of nitrate, ammonium and urea are common.

Please see the protocol for detailed method.

Abstract:

The Santa Barbara Coastal LTER (SBC LTER) is an interdisciplinary research and education program established in April 2000 with the goal of developing a predictive understanding of how environmental drivers interact with terrestrial and oceanic processes to alter material flows and influence the ecology of coastal ecosystems. SBC LTER's principal study domain is the semi-arid coast and nearshore waters of the Santa Barbara Channel in southern California, and its diverse and productive marine forests of giant kelp (Macrocystis pyrifera) serve as the focal study ecosystem. Analyses of our long-term data have identified many of the environmental drivers and ecological processes underlying the production and community dynamics of kelp forests. The research proposed to address this question is integrated in a conceptual framework that focuses on the causes and ecological consequences of the dynamics of a relatively short-lived foundation species in a setting of long-term climate change and human use.
