General Information
Data Package:
Local Identifier:knb-lter-sbc.156.1
Title:SBC LTER: Reef: The size-dependent functional response of lobster foraging on purple urchin
Alternate Identifier:DOI PLACE HOLDER
Abstract:

These data summarize the results of a size-dependent functional response experiment in which California spiny lobster (Panulirus interruptus) foraged on purple urchins (Strongylocentrotus purpuratus). Lobster of different sizes foraged on one of three different size classes of urchins at 4-6 different densities of urchin. Data are contained in one table.

Description:

California spiny lobster are a generalist predator that regularly consume purple urchins. Previous work has shown that lobster-urchin interactions are size dependent. Here, we used mesocosm foraging trials to estimate the size-dependence of the lobster functional response. We collected 45 lobster from the Santa Barbara channel ranging in size from 178- 2736 g. We allowed each lobster to forage on one of three size classes of urchin. Urchin size classes were 10-30, 30-50, and 50-70 mm test diameter. We estimated urchin mass using a test diameter to weight relationship (LINK) where each size class was defined by the mean test diameter of the range (e.g. 20, 40, 60 mm carapace length). For each foraging trial, we fed lobsters ad libidum for 48 hours, starved the lobsters for 48 hours, and then allowed then to forage on a specified density of urchins for 48 hours in 200 L laboratory mesocosms. Urchin densities used in the experiment were 2,3,5,10, 16, and 26 ind. arena-1.

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.
