pyRIVE
No full textThe pyRIVE model aims at representing the biogeochemical functioning of aquatic system, by simulating concentrations of oxygen and nutrients dissolved (NH4+, NO2-, NO3-, PO43-, SiO2) and particulate (PIP, BSi), suspended matter, dissolved and particulate organic carbon (3 classes of biodegradability), dissolved gases (CO2, N2O et CH4). Biological compartments are represented by 3 taxonomic classes of phytoplankton (diatoms, chlorophyceae, and cyanobacteria), 2 types of zooplankton (rotifers with short generation time and microcrustaceans with long generation time), 2 types of heterotrophic bacteria (small autochthonous and large allochthonous) as well as nitrifying bacteria. Faecal bacteria (free and attached) are also considered as state variables. The model also takes into account benthic variables (benthic organic matter, inorganic particulate phosphorus, benthic biogenic silica)
Tree community diversity (composition and structure) along piosphere gradients in Hwange National Park (Zimbabwe)
No full textFifty-nine 50m-long vegetation transects were conducted at 0.5, 1, 2 and 5km and sometimes 8km away from 13 permanent waterholes in Hwange National Park. Along each transect, all woody plants taller than 50cm were surveyed within a 2m strip on each side of the transect, extended to a 10m strip for tall trees (>8m). Information recorded on all individual plant included species identity, height, basal circumference and other information (see variables-description.txt file). Grass height was recorded every 5m along each transect, unless the location was under a tree/bush.
These vegetation surveys were conducted between April and June 2008
δ13C and δ15N stable isotope compositions of the whisker of 24 harbour seals (Phoca vitulina) and 12 grey seals (Halichoerus grypus) captured in the baie de Somme, France, in 2019 and in 2022, for telemetry tracking
No full textδ13C and δ15N stable isotopes values were measured along the whiskers of 24 harbour seals (Phoca vitulina) and 12 grey seals (Halichoerus grypus) captured in the baie de Somme, France, to be fitted with GPS/GSM tags (15 harbour seals and 12 grey seals captured in May and October 2019 ; telemetry tracking data of these individuals are available on https://doi.org/10.17882/89715) and with DTags (9 harbour seals captured in May 2022). The present data are complementary to those obtained previously on 8 harbour seals and 10 grey seals captured in 2008 and in 2012 in the baie de Somme (data available on https://doi.org/10.17882/76528 ; data published as part of Planque et al. (2021), https://doi.org/10.1002/ece3.7739, and Planque (2021), http://dx.doi.org/10.13140/RG.2.2.35986.12480). Seal whiskers provided a temporal integration of isotope compositions during the period of whisker growth, i.e. during months prior to sampling. All whisker segments were analysed with an elemental analyser (Flash 2000, Thermo Scientific, Milan, Italy) coupled to an isotope-ratio mass spectrometer (Delta V Plus with a Conflo IV interface, Thermo Scientific, Bremen, Germany). Isotope compositions are expressed with the usual δ notation in parts per thousands (‰) relative to Vienna PeeDee Belemnite Standard for δ13C and atmospheric N2 for δ15N. Based on replicate measurements of internal laboratory standards, analytical precision is < 0.15 ‰ for both δ13C and δ15N

Thematic data on the potential for lateral erosion reactivation following the removal of ripraps on the Allier River between 2017 and 2022
No full textThe data file contains a set of topographic, granulometric and planform analysis data for two reaches of the Allier River (France) that were studied following the removal of riverbank protections. The objective was to evaluate to what extent riprap removal may be an efficient restoration measure in terms of the reactivation of bank erosion and lateral channel dynamics as well as the replenishment of the local bedload. The dataset contains (1) digital elevation models obtained by LiDAR or photogrammetric surveys on site 1 between November 2017 and February 2022, and on site 2 between February 2020 and October 2022; (2) active channel planform analysis of site 2 and of the control reaches between 2019 and 2022 carried out from aerial satellite images and IGN orthophotographs; (3) granulometric data in the channel and on the restored bank of site 2; (4) topobathymetric surveys and their comparison carried out on site 2 before the restoration work (2018) and after the restoration work in November 2021 and August 2022

Simulated land cover maps for 2080, 2100 and 2120 on the Haut Vicdessos (Pyrenees, France) considering pastoral land use changes scenarios
No full textScenarios based on 3 land use assumptions:
A) Without pastoral management constraints: land cover changes between 2008 and 2080 (or 2100 or 2120) occur at the same rate as those observed between 1983 and 2008.
B) Taking into account the agro-pastoral pressure defined by the agro-pastoral diagnoses established by the Ariège Pastoral Federation. Different pastoral pressure indices are assigned to the 16 Vicdessos summer pastures.
C) Same scenario as B, except that only the estives with high agro-pastoral pressure will be maintained in the future with a maximum pressure index of 1 (for the other summer pastures, the index is 0). The herds of the abandoned summer pasture migrate to those that are maintained
Valeurs de concentration en éléments chimiques dans des mousses collectées en France métropolitaine en 2006
No full textDépourvues de système vasculaire développé et de véritables racines, les mousses sont directement exposées aux variations du milieu. Elles répondent rapidement aux perturbations environnementales et fournissent ainsi des informations utiles sur la qualité des milieux aquatiques et terrestres ainsi que sur les changements globaux. Au travers de très nombreuses études, les mousses terrestres sont apparues comme des bioaccumulateurs efficaces du dépôt atmosphérique particulaire et soluble. La concentration d’un élément dans une mousse permet d'estimer le niveau d’exposition du brin vis-à-vis des contaminants atmosphériques. Cette technique de biosurveillance est une méthode relative qui permet de classer les sites de collecte les uns par rapport aux autres en fonction de la valeur de concentration mesurée dans l’échantillon de mousses.
Le dispositif BRAMM (Biosurveillance des Retombées Atmosphériques Métalliques par les Mousses) permet de cartographier et de modéliser les concentrations en contaminants métalliques et azoté dans des mousses forestières sur l’ensemble du territoire métropolitain. Des campagnes quinquennales sont réalisées depuis 1996 (1996, 2000, 2006, 2011, 2016 et 2021) et portent sur environ 500 sites de collectes répartis sur l’ensemble du territoire. Ces sites sont localisés en milieu rural, loin des sources locales de pollution, et forestier, sous couvert arboré.
Le dispositif BRAMM est la participation française au programme European moss survey piloté par le PIC-Végétation dans le cadre de la Convention de Genève sur la Pollution Atmosphérique Transfrontière à Longue Distance (UNECE-LRATP)
AraDiv: a dataset of functional traits and leaf hyperspectral reflectance of Arabidopsis thaliana
No full textThe AraDiv dataset provides phenotypic and leaf hyperspectral reflectance (NIRS) data for 721 widely distributed Arabidopsis thaliana accessions. Phenotypic data include vegetative, phenological, and reproductive functional traits, constituting a comprehensive dataset of A. thaliana’s intraspecific phenotypic diversity. Phenotyped accessions were grown in a common garden, and meteorological data recorded during the experiment were also included in AraDiv. The common garden experiment was conducted between February and July 2021 under shade cloth in the experimental field of Centre d’Ecologie Fonctionnelle et Evolutive (CEFE), Montpellier, France
