The dataset contains species occurrence records of deep-sea benthic fauna distributed along the Brazilian Continental Margin (BCM). Benthic records from existing and openly...

Stomach contents analysis is a standard dietary assessment method that potentially enables quantifying diet components with high taxonomic resolution. We compiled diet...

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...

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...

Sample sizes: Peterhead Inlet n = 80, Sylvia Grinnell n = 21.

Oceanic food webs are organized in a continuum from microbial to metazoan linked by trophic interactions. Assessment of the position of organisms in the food web, i.e., their...

Isotopic data are valuable to investigate species interactions and food web structure. This file compiles δ13C and δ15N values of various marine taxa; most of data correspond to...

This dataset is a compilation of spatial layers and scientific data underpinning the 2022-23 revision of the nomination proforma for the "North Atlantic Current and Evlanov Sea...

The dataset presents the number of mesopelagic Decapoda collected during the CSIC-SUMMER survey carried out in October 2020 in five zones around the Iberian Peninsula: south of...

Mesopelagic fish collected during 3 field campaigns in 2020 were analysed for their lipid content. The sampling was conducted on 5 main locations; 2 stations in the Western...

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....

This database contains functional traits of target and non-target fish species (Actinopterygii and Elasmobranchii) from the Azores archipelago, Portugal. The included traits are...

Ecosystem models often use wet weights to parameterise biota disregarding their water content. This may be especially erroneous for gelatinous plankton, such as salps and...

The data has been collected during the the year-long drift expedition "Multidisciplinary drifting Observatory for the Study of Arctic Climate" (MOSAiC) from September 2019 to...
