Fractional trophic levels (i.e., trophic positions) describe the position of organisms within food webs and help define their functional roles in ecosystems (Odum & Heald,...

Bulk stable isotope ratios, primarily of carbon (δ13C) and nitrogen (δ15N), are increasingly used to examine predator-prey interactions and food web structure. We compiled δ13C...

Fatty acid (FA) composition has increasingly been used to estimate the dietary preference of marine organisms. Specific fatty acids and fatty acid ratios serve as trophic...

Information on the energy density of prey is critical for estimating food requirements and consumption by predators and modelling energy flux through food webs (Van de Putte et...

This dataset comprises gene expression data in the deep pelagic jellyfish Periphylla periphylla exposed to anthropogenic disturbance. Specifically, we tested the effects of...

This dataset comprises the microbial community composition associated with the outer bell of the deep pelagic jellyfish Periphylla periphylla exposed to anthropogenic...

This dataset comprises the physiological and behavioural stress response of the deep pelagic jellyfish Periphylla periphylla to anthropogenic disturbance. Specifically, we...

The dataset contains the concentrations of 11 essential elements (micro-nutrients) analysed in whole bodies of 78 forage species sampled on the continental shelf or in the...

The freshwater hydrozoan Craspedacusta sowerbii has invaded exotic habitats around the world. This data set contains information on the water and organic content, as well as...

Climate change and anthropogenic disturbances, among other factors, can change the seawater stoichiometry (C/N/P) and consequently elemental ratios of phytoplankton. This change...

Gelatinous and soft-bodied zooplankton (GZ) have long been considered to have low energetic value and are insufficient to sustain higher trophic levels. However, the nutritional...
