Description

The database compiles data (used in Singh et al. In Review, Frontiers in Marine Science) obtained from a laboratory experiment where Juvenile amphipods (Allorchesta compressa) were raised on fresh and aged kelp (Ecklonia radiata (“Type”) that had either been treated with antibiotics or left untreated (Treatment). Aged kelp had been maintained in an aquarium for two weeks to allow bacteria in the biofilm to increase to levels found in surf zones. Treated kelp represented kelp with reduced bacterial abundances, while control kelp represented kelp with natural abundances of bacteria. The experiment comprised 5 replicates for each treatment/type combination. The experiment ran over 6 weeks to examine growth of amphipods, and a further 2 weeks to examine reproductive traits (number of eggs and number of ovigorous females. Bacterial abundances were measured on kelp pieces at intervals throughout the experiment, along with tissue toughness, carbon (C) and nitrogen (N) content and C:N ratios to represent food palatability and quality.

Research Activity Title

Role of microbial assemblages in affecting the nutrient cycling associated with wrack and in supporting the food web of surf zones and sandy beaches

Research Activity Description

This data set formed part of a broader PhD project examining the dynamics of microbial assemblages, nutrients and wrack biomass, and the role of microbes in nutrient cycling and supporting the food web of surf zones and sandy beaches in south-western Australia.
