title: Seasonal chamber measurements of CH4 fluxes and their isotopic composition along with environmental conditions at vegetation removal experiments in hollows at Siikaneva bog, Finland, in 2021 and 2022

description: The data set contains measurements of methane (CH4) emissions and their δ13C values at vegetation removal experiments consisting of three vegetation treatments (intact vegetation, vascular plants removed, all vegetation removed). We took pore water samples for DOC, concentrations and δ13C values of CH4 dissolved in the pore water and measured the peat temperature, each at 7, 20 and 50 cm depth in the peat profile outside of as well as within each vegetation removal area. Additionally, we determined the leaf area index of each vascular plant species present at our sampling sites and measured the water table depth. One complete set of measurements consisted of manual chamber CH4 flux measurements at five spatial replicates of the plot cluster consisting of the three vegetation treatments. Each chamber measurement was performed once under light and once under dark conditions. In summer 2021 each measurement was additionally performed under single and double shading of the measurement plot. Pore water sampling and peat temperature measurements were performed once in an area of intact vegetation and once within the area where vascular plants had previously been removed at each of the five spatial replicates. Water table depth was measured once per spatial replicate. Such measurement sets were collected at the hollow microtopography type of Siikaneva bog in South-Western Finland, in July, August and October 2021 as well as in May, July, September and October 2022. Data on CH4 dissolved in the pore water is available only from the 2022 campaigns. We combined CH4 flux measurements on vegetation removal experiments with pore water concentrations and isotopic data to identify the seasonal change in the components of CH4 fluxes (production, oxidation, transport pathways) as well as in their environmental and ecological controls.

title: Compilation of new data on stable nitrogen and carbon isotope ratios of marine biota from the subarctic and temperate Atlantic, and western Mediterranean Sea

description: 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 mesopelagic fish, but mesopelagic cephalopods, decapods and zooplankton, and cetaceans are also represented. This dataset follows a previous data file presented in Silva et al. (2022b) (https://doi.pangaea.de/10.1594/PANGAEA.945917) and maintains the same layout. A total of 1045 records are included, of which 612 correspond to mesopelagic fish (55 species), 18 to non-mesopelagic fish (1 species), 168 to decapods (7 species), 68 to marine mammals (12 species), 5 to Cephalopoda (2 species) and 174 to zooplankton (14 taxa). Data are available for the subarctic and temperate Atlantic, the northeast Atlantic (off the Iberian Peninsula, Azores, and Bay of Biscay), and the Western Mediterranean. Samples come from years 2002 to 2021, and expand to all seasons. The table contains data on bulk stable isotope ratios of carbon (δ13C) and nitrogen (δ15N), and the total organic carbon to nitrogen ratio (C/N) measured in sample tissues or in the whole body of organisms are presented in this file. To eliminate the effect of lipids on δ13C values, lipids were extracted from samples before analysis (column "δ13C_LE (delipized)", or in other cases a mathematical correction was applied a posteriori (column "δ13C_Lipid Corrected"). For each data record, it is provided the sampling location, geographic coordinates, month and year of sample collection, method of sample collection, taxonomic ranks (phylum, class, order, family), number and size (or size range) of sampled organisms, as well as the reference and DOI of the original data source, for further details on the samples analysed and/or the analytical techniques used.

title: Compilation of new estimations on trophic positions of marine biota from the temperate Atlantic and western Mediterranean

description: 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 Trophic Level (TL) can be made by from direct analyses of stomach contents or indirectly using tracers like stable isotopes. The present file gives TL for marine organism derived from isotopic data (δ15N) presented in Olivar et al. (submitted to PANGAEA). This file follows a previous data file on TL of mesopelagic organism by Silva et al. (2022) and keeps the same layout. We present estimates of Trophic Levels from 770 samples encompassing 32 species of mesopelagic fish, 7 of crustacean decapods, and 17 species of cetaceans. Fish and crustacean samples come from the temperate Atlantic (Azores, Bay of Biscay, western Iberian Peninsula), and from the western Mediterranean. The baseline to calculate TL for the western Iberian Peninsula and western Mediterranean organisms were the isotopic data of herbivorous copepods obtained concurrently, while for the Bay of Biscay values of the euphausiid Meganyctiphanes norvegica were used. All the cetaceans (order Cetartiodactyla) come from the Azores or the Bay of Biscay. Western Iberian Peninsula and western Mediterranean mesopelagic fish diets from stomach content analyses of the same specimens included in this table are given in Bernal et al. (2023). For each data record, it is provided the sampling location, geographic coordinates, month and year of sample collection, method of sample collection, taxonomic ranks (phylum, class, order, family), number and size (or size range) of sampled organisms, type of analyses and estimation method, as well as the reference and DOI of the original data source, for further details on the samples analysed and/or the analytical techniques used.

title: Cranidial and pygidial measurements, and cranidial landmark data of Sahtuia carcajouensis and Mackenzieaspis parallelispinosa

description: This dataset contains measurements and landmark data taken from two species of middle Cambrian trilobite from the Northwest Territories of Canada. This was conducted to quantify their growth and development. Following collection, specimens were prepared in the laboratory, coated in ammonium chloride sublimate, and then photographed, either with a Nikon DSLR camera, or an Olympus SZX-16 microscope. Linear measurements and landmark positions were collected from photos using the software ImageJ version 1.53. Linear measurements were taken from the cranidia and pygidia, and landmarks were only collected from the cranidia. Specimens are labeled as either their Geological Survey of Canada type number (published specimens) or as their original designation number (unpublished specimens). Linear measurements of cranidia and pygidia are expressed in millimeters, whereas landmark data are expressed as x and y coordinates. Landmarks have been fitted using Bookstein method, calculated in Past4.04.

title: Informational Unification of Fundamental Interactions: An Operator-Based Framework with Emergent Spectral Hierarchies

description: We present an exploratory, operator-based framework in which the variety of fundamental interactions is approached from an informational perspective. The framework is built around a single functional acting on a relational substrate, combining local, non-local, and hierarchical contributions together with an irreversible cost term. Rather than treating gauge symmetries as fundamental inputs, the approach investigates whether structured interaction sectors can be associated with distinct stability properties of this operator.

The physical content of the proposal is examined through the spectral properties of the Hessian of the informational functional. In this setting, the organisation of eigenvalues is used as a diagnostic tool to characterise the presence or absence of hierarchical structures that may be interpreted as interaction sectors. No attempt is made to derive specific gauge groups or coupling constants.

A sequence of computational toy models is introduced to probe the internal consistency of the framework. These models are analysed through systematic comparisons with carefully defined null constructions, using spectral entropy, gap-based measures, and concentration indicators. The results show that non-trivial spectral hierarchies arise only when the full informational structure is present, and are suppressed when key terms are removed. Robustness tests across scales, system sizes, and coupling regimes suggest that these features are not solely attributable to fine-tuned parameter choices.

The framework is intended as a pre-unificatory, information-theoretic investigation rather than a complete unification scheme. Its purpose is to clarify how interaction-like structures might emerge from a single operator, and to provide a transparent computational setting in which such ideas can be tested and refined.
