Bottom trawling in the deep sea is one of the main drivers of sediment resuspension, eroding the seafloor and altering the content and composition of sedimentary organic matter (OM). The physical and biogeochemical impacts of bottom trawling were studied on the continental slope of the Gulf of Castellammare, Sicily (southwestern Mediterranean), through the analysis of two triplicate sediment cores collected at trawled and untrawled sites (<span classCombining double low line"inline-formula">ĝ'1/4550</span> m water depth) during the summer of 2016.

17 p, 1.8 MB Gap-filling a spatially explicit plant trait database : comparing imputation methods and different levels of environmental information / Poyatos López, Rafael (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sus, Oliver (European Organisation for the Exploitation of Meteorological Satellites, Organització Europea per a l'Explotació de Satèl·lits Meteorològics) ; Badiella Busquets, Llorenç (Universitat Autònoma de Barcelona. Servei d'Estadística Aplicada) ; Mencuccini, Maurizio (Centre de Recerca Ecològica i Aplicacions Forestals) ; Martínez Vilalta, Jordi, 1975- (Centre de Recerca Ecològica i Aplicacions Forestals)
The ubiquity of missing data in plant trait databases may hinder trait-based analyses of ecological patterns and processes. Spatially explicit datasets with information on intraspecific trait variability are rare but offer great promise in improving our understanding of functional biogeography. [...]

12 p, 3.1 MB Automatic high-frequency measurements of full soil greenhouse gas fluxes in a tropical forest / Courtois, Elodie A. (University of Antwerp. Department of Biology) ; Stahl, Clément (Université des Antilles. AgroParisTech) ; Burban, Benoit (Université des Antilles. AgroParisTech) ; Berge, Joke Van den (University of Antwerp.

Measuring in situ soil fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) continuously at high frequency requires appropriate technology. We tested the combination of a commercial automated soil CO2 flux chamber system (LI-8100A) with a CH4 and N2O analyzer (Picarro G2308) in a tropical rainforest for 4 months. [...]

22 p, 2.8 MB The influence of soil properties and nutrients on conifer forest growth in Sweden, and the first steps in developing a nutrient availability metric / Van Sundert, Kevin (University of Antwerp. Centre of Excellence PLECO (Plants and Ecosystems)) ; Horemans, Joanna A. (University of Antwerp. Centre of Excellence PLECO (Plants and Ecosystems)) ; Stendah, Johan (Swedish University of Agricultural Sciences. Department of Soil and Environment) ; Vicca, Sara (University of Antwerp. Centre of Excellence PLECO (Plants and Ecosystems))
The availability of nutrients is one of the factors that regulate terrestrial carbon cycling and modify ecosystem responses to environmental changes. Nonetheless, nutrient availability is often overlooked in climate-carbon cycle studies because it depends on the interplay of various soil factors that would ideally be comprised into metrics applicable at large spatial scales.

17 p, 7.3 MB The devil's in the disequilibrium : sensitivity of ocean carbon storage to climate state and iron fertilization in a general circulation model / Eggleston, Sarah (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Galbraith, Eric D. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Ocean dissolved inorganic carbon (DIC) storage can be conceptualized as the sum of four components: saturation (DICsat), disequilibrium (DICdis), carbonate (DICcarb) and soft tissue (DICsoft). Among these, DICdis and DICsoft have the potential for large changes that are relatively difficult to predict. [...]

Planktic foraminifera were collected with 150 µm BONGO nets from the upper 200 m water depth at 20 stations across the Mediterranean Sea between 2 May and 2 June 2013. The main aim is to characterize the species distribution and test the covariance between foraminiferal area density (ρA) and seawater carbonate chemistry in a biogeochemical gradient including ultraoligotrophic conditions.
