SBC LTER: Reef: Coefficients for estimating biomass from body size or percent cover for kelp forest species

General Information

Data Package:
Local Identifier:	knb-lter-sbc.127.4
Title:	SBC LTER: Reef: Coefficients for estimating biomass from body size or percent cover for kelp forest species
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	These data provide coefficients to estimate the biomass of macroalgae, invertebrates and fish from field measurements of body size or percent cover. We developed quantitative relationships between mass and length or mass and percent cover, and conversion factors for transforming wet mass into dry mass, shell free and decalcified dry mass, and ash-free dry mass for 103 taxa of benthic macroalgae and macroinvertebrates common to giant kelp forests in southern California. We also compiled literature-based relationships between mass and total length for 52 species of reef fish common to giant kelp forests in southern California.

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.
