Abstract

The mangrove ecosystem is diverse and its species composition varies longitudinally around the world, therefore, primary productivity based on litterfall has been extensively studied. In the present study, litter production was evaluated for three years to identify patterns in relation to physical chemicals of water and sediment. Litter fall was measured by means of traps, in addition, chemical physics (salinity, redox potential, conductivity, temperature and pH) of surface, interstitial and groundwater, and mangrove sediments (Texture, pH, organic matter, bulk density and moisture content) were measured. The main results showed that litter production registered low interannual variation, with 5.15 ton•ha-1•year-1 the first year (2014-2015), the second year (2015-2016) was 5.1 ton•ha-1•year-1and the third year (2016-2017) registered a lower production with 4.93 ton•ha-1•year-1, with high influence of salinity levels, flood pattern and rainfall, in addition to the type of substrates fines (clays) maintain the conditions for retaining moisture and organic matter, which allow the mangrove a greater recycling of nutrients in situ, which is reflected in greater primary productivity. Likewise, the negative response in the production of mangrove litter to the increase in salinity emphasizes the need to document these processes in the face of global climate change scenarios.

Full professor researcher "C". Field of specialization: Hydrobiology with special reference to the ecology of shallow aquatic ecosystems. The Doctor obtained his bachelor's degree in Biology at the Faculty of Sciences UNAM, a master's degree in Biological Oceanography and a doctorate in Marine Sciences at the UACPyP-CCH UNAM. He was Associate Researcher C at the Institute of Marine Sciences and Limnology of UNAM where he served as President of the Faculty of Researchers. In 1997, he joined the Academic Division of Biological Sciences at the Universidad Juárez Autónoma de Tabasco, where he is Research Professor Titular C de TC, responsible for the Consolidated Academic Body "Diagnosis and Management of Tropical Wetlands", level I in the S:NI, Regular member of the Mexican Academy of Sciences. Previously, he received the Scientific Merit Award at UJAT. He served as Academic Secretary of the Center for Global Change and Sustainability in the Southeast; Research and Postgraduate Coordinator in the Academic Division of Biological Sciences, UJAT; and Head of the Editorial Department of University Magazines of the Secretariat of Research, Postgraduate and Linkage, UJAT. For eight years he was editor of the journal Universidad y Ciencia, a period in which recognition was obtained by the Index of Mexican Journals of Scientific and Technological Research of CONACyT. He also directed the "Design of the Tabasco Water Institute" project. He has published 30 indexed articles, 6 books, 19 peer-reviewed book chapters, and 68 articles in non-indexed national and international peer-reviewed scientific and popular journals and in extensive memoirs. His lines of research include: 1) evaluation of the ecological condition of coastal wetlands, 2) macrofauna distribution patterns, and 3) trophic ecology. Since 1988 he taught undergraduate courses at the Faculty of Sciences, later a master's degree at the same Faculty and a Doctorate in Biological Oceanography at UACPyP, UNAM. Currently, he teaches courses and seminars related to aquatic biology, limnology and ecology of estuarine organisms in the Bachelor of Biology UJAT, Master of Environmental Sciences UJAT, Master of Sciences in Restoration of Coastal Ecosystems UNACAR and Doctorate in Sciences in Ecology and Management of Tropical Systems UJAT. He has trained 22 undergraduate students, eight master's students and four doctoral students. He directed two postdoctoral stays. He collaborated as a visiting scientist (2006-2007) at the Smithsonian Environmental Research Center, Smithsonian Institution, in the U.S.A. It is participating in several networks, among which the "Network for the Knowledge of Coastal Resources of the Southeast of Mexico" stands out, whose products include the creation of the Master's Degree in Sciences in Restoration of Coastal Ecosystems UNACAR, recognized in the PNPc and the Publication of the book Aquatic Resources of the Southeast.
