  • Anthropogenic and environmental influences on nutrient accumulation in mangrove sediments 
    Pérez, Alexander; Machado, Wilson; Sanders, Christian J. (Elsevier, 2021)
    Here we provide a global review on nutrient accumulation rates in mangroves which were derived from sixty-nine dated sediment cores, addressing environmental and anthropogenic influences. Conserved mangroves presented ...
  • Carbon and Nitrogen Contents Driven by Organic Matter Source within Pichavaram Wetland Sediments 
    Naidu, Sathy A.; Kathiresan, Kandasamy; Simonson, Jeffery H.; Blanchard, Arny L.; Sanders, Christian J.; Pérez, Alexander; Post, Ruth M.; Subramoniam, Thanumalaya; Naidu, Raj A.; Narender, Rajendran (MDPI, 2022)
    Differences in grain size, total organic carbon (OC), total nitrogen (TN), OC/TN ratios, and stable isotope (δ13C and δ15N) were assessed in sediments from areas covered by mangrove and saltmarsh vegetation within Pichavaram ...
  • Climate change, migrations, and the peopling of sine-Saloum mangroves (Senegal) in the past 6000 years 
    Carré, Matthieu; Quichaud, L.; Camara, A.; Azzoug, M.; Cheddadi, R.; Ochoa, Diana; Cardich Salazar, Jorge Aquiles; Pérez, Alexander; Salas-Gismondi, Rodolfo; Thébault, J.; Thomas, Y. (Elsevier, 2022)
    We present a reconstruction of human demography and shell fishing activity in the Sine-Saloum mangrove Delta (Senegal) in the past 6000 years using the summed probability density (SPD) of radiocarbon dates in archaeological ...
  • Factors influencing organic carbon accumulation in mangrove ecosystems 
    Pérez, Alexander; Libardoni, Bruno G.; Sanders, Christian J. (Royal Society Publishing, 2018)
    There is growing interest in the capacity of mangrove ecosystems to sequester and store 'blue carbon'. Here, we provide a synthesis of 66 dated sediment cores with previously calculated carbon accumulation rates in mangrove ...
  • High-resolution marine data and transient simulations support orbital forcing of ENSO amplitude since the mid-Holocene 
    Carré, Matthieu; Braconnot, Pascale; Elliot, Mary; d'Agostino, Roberta; Schurer, Andrew; Shi, Xiaoxu; Marti, Oliver; Lohmann, Gerrit; Jungclaus, Johann; Cheddadi, Rachid; Abdelkader-di Carlo, Isma; Cardich Salazar, Jorge Aquiles; Ochoa, Diana; Salas-Gismondi, Rodolfo; Pérez, Alexander; Romero, Pedro E.; Turcq, Bruno; Corrège, Thierry; Harrison, Sandy P. (Elsevier, 2021)
    Lack of constraint on spatial and long-term temporal variability of the El Niño southern Oscillation (ENSO) and its sensitivity to external forcing limit our ability to evaluate climate models and ENSO future projections. ...
  • Organic matter redox state driven by specific sources in mangrove sediments: A case study from peruvian ecosystems 
    Pérez, Alexander; Cebrián-Torrejón, Gerardo; Montoya, Noemí; Piquero-Cilla, Joan; Sanders, Christian J.; Doménech-Carbó, Antonio; Machado, Wilson (MDPI, 2021)
    In order to determine the organic matter redox state in relation to specific sources in mangrove sediments, two 60 cm-long sediment cores were collected from mangrove-covered and mudflat zones within a mangrove forest in ...
