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...

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...

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,...

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...

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

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...

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...

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....

Stream benthic macroinvertebrates were collected for a period of 3 consecutive months (December 2019 to March 2020), in 4 nested/non-nested sites within the catchment of Val...

All studies included in the meta-analysis are listed with study details such as experimental design, species studied, number of replicates, salinity levels and mean values and...

Compiled marine radiocarbon data from the global ocean, derived from planktonic/benthic foraminifera and corals, spanning the last deglaciation, with associated calendar ages...

Age BP = 1950Record key: 1 - TRA7, 2 - FN1a, 3 - FN2, 4 - TRA5, 5 - FN1b

Temperature was measured at 15-minute intervals between March 21 and September 17, 2022. The temperature dataset includes: (1) continuous measurements of air temperature from a...

This data set comprises CTD data of the RV ALKOR cruise AL607 conducted in February 2024 (February 10th – February 16th) in the Western Baltic Sea by the University of Hamburg....

This data set comprises CTD data of the RV ALKOR cruise AL606 conducted in January 2024 (January 22nd – January 30th) in the Western Baltic Sea by the University of Hamburg. The...

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...

This data set comprises CTD data of the RV ALKOR cruise AL549 conducted in January 2021 (January 25th – February 1st) in the Western Baltic Sea by the University of Hamburg. The...

This data set comprises CTD data of the RV ALKOR cruise AL585 conducted in January 2023 (January 23rd – January 31st) in the Western Baltic Sea by the University of Hamburg. The...
