Soil biota (earthworm, nematode and soil surface fauna) data of organic, permaculture and conventional horticultural farms of Central Hungary

This dataset has been produced from the PhD research of Alfréd Szilágyi supervised by Csaba Centeri and Eszter Kovács Tormáné. The study compared permaculture, organic and conventional farming systems regarding their ecosystem-service provision potential and sustainability. Multiple ecological indicators were measured in the field during the field study in 2020, and the basic datasets (soil test results; photo gallery of the studied farms with soil core sample; soil resistance and moisture; decomposition; earthworms; nematodes; soil surface fauna; pollinators; agrobiodiversity and habitat types) are uploaded in Zenodo separately to provide scientific data on permaculture systems. In this way, we hope to contribute to international efforts to evaluate the performance of agroecological agriculture alternatives. These publications also serve as supplements to the PhD thesis. For the sake of further usability of the datasets short description of the used methods is described. For further information please contact the authors.

Global warming effects of cropland expansion by reduction of biogenic secondary organic aerosols

This is the dataset to support our paper title of “Global warming effects of cropland expansion by reduction of biogenic secondary organic aerosols”. Cropland expansion has been the most significant global land use change since industrialization. However, evaluations of radiative forcing from land use changes have often neglected the radiative effects of secondary organic aerosols (SOA) linked to cropland expansion. Sensitivity experiments using an Earth system model that incorporates advanced SOA processes reveal approximately a 10% reduction in the global biogenic SOA burden due to cropland expansion since industrialization. This reduction weakens SOA’s role in scattering radiation and forming clouds, leading to a decline in its cooling effect by 146 mW m⁻², which is equivalent to 8% of the warming caused by CO₂ emissions since industrialization. This effect is expected to increase by nearly half under future climate warming and reduced emissions scenarios. Therefore, policies addressing food security and climate change must consider the radiative impacts of biogenic SOA associated with cropland expansion.   The dataset consists of three zip files, which include model code and output from sensitivity simulations conducted with the Community Earth System Model (CESM) version 1.2.2, using the IMPACT aerosol module and an offline radiative model. The files are described as follows:   Model code.zip: Contains the source code for the IMPACT aerosol module, which was integrated as an additional aerosol module within CESM version 1.2.2, available from the NCAR repository.   PD_Cases.zip: This file contains two folders (Concentration and Radiation), which hold the simulation results for concentration and radiation in present-day cases. The Concentration folder includes 13 subfolders. The Radiation folder contains four subfolders representing different radiation simulation results. These include simulations with and without the direct radiative effects of SOA (labeled ADEwSOA and ADEwoSOA respectively) and simulations with and without the indirect radiative effects of SOA (labeled AIEwSOA and AIEwoSOA respectively). Each of these subfolders contains 13 additional subfolders, which share the same names as those in the Concentration folder. These 13 subfolders correspond to specific sensitivity experiments, the details of which are explained below. Within each subfolder, you will find the five-year averaged model output for all 12 months. 18L20E20C represents simulations with pre-industrial land use, and present-day emissions and climate conditions; 20L20E20C represents simulations with present-day land use, emissions, and climate conditions. Eight subfolders for single vegetation type transition experiments include model output for cases where land use transitions from deciduous broadleaf forest to cropland (DBF2CRO), evergreen broadleaf forest to cropland (EBF2CRO), evergreen needleleaf forest to cropland (ENF2CRO), grassland to cropland (GRA2CRO), shrubland to cropland (SHR2CRO), deciduous broadleaf forest to grassland (DBF2GRA), evergreen broadleaf forest to grassland (EBF2GRA), and evergreen needleleaf forest to grassland (ENF2GRA). Three subfolders for latitude-specific experiments cover conversions for all vegetation types in tropical (20°S–20°N, LLAT), mid-latitude (50°S–20°S and 20°N–50°N, MLAT), and high-latitude (south of 50°S and north of 50°N, HLAT) regions.   FU_Cases.zip: This file contains two folders (Concentration and Radiation), which hold the simulation results for concentration and radiation in future cases. The Concentration folder includes 4 subfolders. The Radiation folder contains four subfolders representing different radiation simulation results. These include simulations with and without the direct radiative effects of SOA (labeled ADEwSOA and ADEwoSOA respectively) and simulations with and without the indirect radiative effects of SOA (labeled AIEwSOA and AIEwoSOA respectively). Each of these subfolders contains 4 additional subfolders, which share the same names as those in the Concentration folder. These 4 subfolders correspond to specific sensitivity experiments, the details of which are explained below. Within each subfolder, you will find the five-year averaged model output for all 12 months. 18L20E21C represents simulations with pre-industrial land use, and present-day emissions, and future climate conditions; 18L21E21C represents simulations with pre-industrial land use, future emissions, and future climate conditions; 20L20E21C represents simulations with present-day land use, and present-day emissions, and future climate conditions; 20L21E21C represents simulations with present-day land use, future emissions, and future climate conditions.

Consumer biodiversity increases organic nutrient availability across aquatic and terrestrial ecosystems

Human land-use intensification threatens arthropod (e.g., insect and spider) biodiversity across aquatic and terrestrial ecosystems. Insects and spiders play critical roles in ecosystems by accumulating and synthesizing organic nutrients like polyunsaturated fatty acids (PUFA).  However, links between biodiversity and nutrient content of insect and spider communities have yet to be quantified. We relate insect and spider richness to biomass and PUFA-mass from stream and terrestrial communities encompassing nine land-uses. PUFA-mass and biomass relate positively to biodiversity cross ecosystems. In terrestrial systems, human-dominated areas have lower biomass and PUFA-mass than more natural areas, even at equivalent levels of richness. Aquatic ecosystems have consistently higher PUFA mass than terrestrial ecosystems. Our findings reinforce the importance of conserving biodiversity and highlight unique benefits of aquatic biodiversity. This is all of the data and code required to reproduce the analyses.  The repository doesn't allow specific folder structures, but the data should ideally be organized into  folders organized and named as follows -     1_raw_data/ ├─ bdm_data/ │  ├─ bdm_families_list.csv ├─ pufa_concentration_data/ │  ├─ Literature_estimates/ │  │  ├─ Literature_estimates.xlsx │  ├─ Margaux_PUFA_Conc/ │  │  ├─ 2a.Lunz 2019_FA_InsectTransfer - Content.xlsx │  │  ├─ 3a.Lunz 2019_FA_InsectConsu - Content.xlsx │  ├─ Martin_Creuzberg_PUFA_Conc/ │  │  ├─ all_STOTEN.xlsx │  ├─ Tarn_PUFA/ │  │  ├─ Mindelsee_FA.xlsx ├─ wsl_data/ 2_modified_data/ ├─ terr_insects_nutrients_null.rds ├─ aq_insect_nutrients_null.rds ├─ aquatic.data.rds ├─ terrestrial_data.rds ├─ insect_data/ │  ├─ aq_insect_regressions.rds │  ├─ te_insect_regressions.rds ├─ null_models/ │  ├─ aquatic_habitat_all.rds │  ├─ terrestrial_habitat_all.rds 3_r_scripts/ ├─ Diversity_Analaysis.rmd ├─ Null_models.rmd ├─ Nutrient_content.rmd ├─ Scaling_relationships.rmd
