Abstract:

These data describe the position of four burrowed talitrid amphipod species (Megalorchestia spp.) and unidentified juveniles surveyed on a spring tide and a neap tide in August 2016. The data table includes the counts of each species, including unidentified juveniles, from each core sample (1-30) on each transect (A-F). The distance of the sample from the bluff (0 m) is also given.

The dataset is to support the journal article: Emery, KA, VR Kramer, NK Schooler, KM Michaud, JR Madden, DM Hubbard, RJ Miller, JE Dugan. 2021. Habitat partitioning by mobile intertidal invertebrates of sandy beaches shifts with the tides. Ecosphere.

Description:

Species of the talitrid amphipod, Megalorchestia spp., are the dominant consumers of kelp wrack on sandy beaches in southern California. Population dynamics of these consumers have been studied at length by the Santa Barbara Coastal Long Term Ecological Research program. Since multiple species can coexist on the same beach and seemingly utilize the same resources, we undertook a study to explore for potential spatial separation in habitat use and how that may be mediated by tide phase. On a spring tide and on a neap tide, we established 6 cross-shore transects and took 30 evenly spaced sediment cores (10 cm diameter, 20 cm depth) from the base of the bluff (0 m) to the lowest extent of talitrid amphipod burrows. Each core was rinsed in a mesh bag, stored in a Ziplock bag, and frozen before being sorted in the laboratory. Talitrids were identified to species level except for juveniles (<8 mm body length) and counted.

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.
