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,...

Organisms accumulate major and trace elements (including metals) directly from the external environment and/or indirectly through diet. As such, their elemental composition can...

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...

Quantitative data on diet composition is key to understand prey–predator interactions and to parameterize ecosystem models. We compiled estimates of diet proportions from 26...

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...

The dataset contains energy density values and concentrations in 19 elements analysed in whole bodies of 15 meso- to bathypelagic species sampled in the twilight zone (deep...

The dataset contains carbon (C) and nitrogen (N) stable isotope compositions analysed in the muscle tissue of 15 meso- to bathypelagic species sampled in the twilight zone (deep...

An experimental approach was developed to assess the individual and combined effects of two climate change stressors (seawater temperature and POC quality) on deep-sea benthic...

The dataset contains 108 records of major and trace element concentrations measured on (eviscerated) whole bodies of meso- to bathypelagic fish (19 species), decapods (4...

The dataset contains 361 records of energy density values measured on (eviscerated) whole bodies of meso- to bathypelagic fish (49 species), decapods (4 species) and euphausiids...

This file contains data on mesopelagic fish stomach content reported as the number of prey categories in each fish stomach and their carbon masses. These data come from samples...

This file contains data on numerical abundance of larvae and transforming stages of fishes collected during the CSIC-SUMMER survey carried out in October 2010 in five zones...

Stable isotope analysis (SIA) has emerged as a valuable tool for understanding the trophic structure of the marine food web and gaining insights into trophic levels and niche....

We used carbon and nitrogen stable isotope (δ13C and δ15N) analyses to investigate the trophic network of the CWC reef habitat off Angola (SE Atlantic Ocean). Samples were...

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 values of natural abundance of stable isotopes were measured in 13 micronekton fish species sampled during the BATHYPELAGIC cruise (North Atlantic, June 2018). This dataset...

This file contains data on numerical abundance of mesopelagic fishes collected in winter (December 2009) and summer (July 2010) in the Balearic Islands region. A relatively...

The Deep-sea Sponge Microbiome Project is a large-scale study, integrating 16S amplicon sequencing data of seawater, sediment, and sponges, with a large set of ecological and...

Records of distribution of deep-sea lithistids (Porifera, Heteroscleromorpha) of the Azores archipelago

Alpine lakes support unique communities which may respond with great sensitivity to climate change. To understand the drivers of benthic macroinvertebrate community structure,...
