This data set contains information on spermatic cyst development in the coral Dendrophyllia ramea: spermatic cysts sizes and maturation stage are included. A total of three...

This data set contains information from counts of oocytes per mesentery in the coral Dendrophyllia ramea: results are givien as number of oocytes per analysed mesentery. A total...

This data set contains information on oocyte developmental stages for the coral Dendrophyllia ramea: oocyte sizes and maturation stages are included. A total of three polyps...

This data set contains information from counts of oocytes per polyp of the coral Dendrophyllia_ramea: these data have been used to calculate fecundity. A total of three polyps...

The values of carbon flux were determined in juveniles/adults of 3 species of migratory mesopelagic fishes, 2 species of decapods and 2 species of large euphausiids sampled...

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...

Here we present the elementary composition [ln(Fe/K) and ln(Al/K)] from suspendend sediment samples for Negro, Solimões and Amazon Rivers (northern and south channels) during a...

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...

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...

Measurements of body size (prosome length), dry weight, and lipid content (oil sac area and volume) in wild-caught copepods were compiled from multiple studies conducted in the...

In November 2022, February 2023, and May 2023, six red-crowned cranes were released into the Yancheng National Nature Reserve for Rare Birds, to increase the western migratory...

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...
