Abstract:

These data describe measures of excretion from talitrid amphipods (Megalorchestia corniculata) fed giant kelp (Macrocystis pyrifera) blades and incubated in a series of mesocosms during May 2018. Data are contained in one table: time series of mesocosm porewater nutrient concentrations measured twice daily for approximately one week (two full trials included in this dataset).

This dataset is to support the article: Lowman, H. E., Emery, K. A., Kubler-Dudgeon, L., Dugan, J. E., & Melack, J. M. (2019).

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

Two identical experimental trials to measure talitrid amphipod excretion were conducted in May 2018. Dry sand was collected from Isla Vista beach and sieved using 1.5 mm mesh. The sand was not rinsed so that existing microbial communities would remain intact, and mesocosm conditions would approximate in situ conditions on the beach. Kelp blades were collected from the Isla Vista Reef kelp forest and submerged in a flow-through seawater tank until needed. Nine high-density polyethylene buckets were assembled containing 8.5 cm of dry sand (surface area = 715 cm2) mixed with 1.25 L of unfiltered seawater. Six of the nine buckets received a single fresh kelp blade that was replaced every two days. Three of the buckets that contained kelp also received 40 adult talitrid amphipods (Megalorchestia corniculata), collected the morning of the trial at Isla Vista beach. The three remaining buckets without kelp or talitrids were the controls and contained only sand and seawater. The three treatments were repeated during both trial runs to create six total replicates of each treatment. All buckets were fitted with a screened top to prevent the organisms from escaping and a valve at the bottom to allow for pore water extraction. The buckets were exposed to natural light cycles at a temperature of 22˚ C. Water was sampled from the bottom valve three times in the first 24 hours, and once every 12 hours thereafter. At each time, 100 mL of pore water was extracted using a 60 mL syringe connected to the valve, and 100 mL of fresh seawater was poured onto the surface of the sand. Water samples were filtered through GF/F filters (Whatman, 0.7µm) prior to analysis for dissolved nutrients. Water samples were analyzed for NH4 + immediately using the ortho-phthaldialdehyde (OPA) method and measured on a Turner Trilogy fluorometer (limit of detection (LOD) = 0.05 µM). Additional samples were frozen until analysis for NO3 - concentrations with the high throughput flow injection analysis method using a Lachat Flow Injection Analyzer (LOD = 0.5 µM).

Note: The ammonium values measured during Trial 1 at Timepoint 24 were removed from the dataset analyzed for the below publication due to contamination concerns.

Abstract:

The primary research objective of the Santa Barbara Coastal LTER is to investigate the importance of land and ocean processes in structuring giant kelp (Macrocystis pyrifera ) forest ecosystems. As in many temperate regions, the shallow rocky reefs in the Santa Barbara Channel, California, are dominated by giant kelp forests. Because of their close proximity to shore, kelp forests are influenced by physical and biological processes occurring on land as well as in the open ocean. SBC LTER research focuses on measuring and modeling the patterns, transport, and processing of material constituents (e.g., nutrients, carbon, sediment, organisms, and pollutants) from terrestrial watersheds and the coastal ocean to these reefs. Specifically, we are examining the effects of these material inputs on the primary production of kelp, and the population dynamics, community structure, and trophic interactions of kelp forest ecosystems.
