description This study was carried out within the framework of the project: “Impacto de la Variabilidad y Cambio Climático en el Ecosistema de Manglares de Tumbes”. Supported by the International Development Research Centre (IRDC) of Canada under management of the Instituto Geofísico del Perú (IGP), in cooperation with the Instituto del Mar del Perú (IMARPE) and the Universidad Peruana Cayetano Heredia (UPCH). The authors acknowledge the program Cátedra CONCYTEC en Ciencias del Mar, which supported the realization of this thesis as well. Detailed geochemical analyses were supported by the IRDC and by the project MINIOX (IMARPE), and were performed in the Marine Geology Laboratory of IMARPE and in the Marine Science Laboratory of UPCH. CJS is supported by the Australian Research Council (DE160100443, DP150103286 and LE140100083). We would like to thank our colleagues Luis Quipuzcoa, Ernesto Fernández, Wilson Carhuapoma, Percy Montero, Rubén Alfaro, Manuel Vera, and Bruno G. Libardoni, without their help this study would not have been possible. We also are grateful to Dr. Ken Takahashi, Douglas Tait and Dr. Wilson Machado, who provided us with invaluable suggestions since the early stage of this study.

We also are grateful to Dr. Ken Takahashi, Douglas Tait and Dr. Wilson Machado, who provided us with invaluable suggestions since the early stage of this study.A tropical mangrove forest in Northern Peru was studied to determine if physical and biogeochemical characteristics of creek water and subtidal sediments are related to the seasonal hydrological regimes. The results showed that during the dry season, there were greater reducing conditions (Eh) and greater fine particle content (silt and clay) in the subtidal sediments. In contrast, the wet season showed greater dissolved oxygen concentrations in creek water as well as lower total organic matter and chlorophyll-a contents in the subtidal sediments. Carbohydrate and protein concentrations indicated remobilization and degradation of sedimentary organic matter, which were higher during the dry season than in the wet season. The results presented here indicate that changes in the hydrological regime affect the biogeochemical dynamics of mangroves, modulating the sediment redistribution as well as the organic matter deposition and degradation. This research provides insight to the biogeochemical dynamics in Peruvian mangrove sediments which are sensitive to extreme El Niño-Southern Oscillation events and the potential effects of climate change.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengSpringer Science and Business Media LLCHydrobiologiainfo:eu-repo/semantics/openAccessdepositioNBiogeochemistry-1concentration (composition)-1concentration (composition)-1degradation-1https://purl.org/pe-repo/ocde/ford#3.02.00-1Hydrological controls on the biogeochemical dynamics in a Peruvian mangrove forestinfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/1340oai:repositorio.concytec.gob.pe:20.500.12390/13402024-05-30 15:36:40.939http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="5ad57b5d-a031-4f27-8b70-fb6f168b04e7"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Hydrological controls on the biogeochemical dynamics in a Peruvian mangrove forest</Title> <PublishedIn> <Publication> <Title>Hydrobiologia</Title> </Publication> </PublishedIn> <PublicationDate>2017-02-23</PublicationDate> <DOI>https://doi.org/10.1007/s10750-017-3118-2</DOI> <Authors> <Author> <DisplayName>Pérez, Alexander</DisplayName> <Person id="rp03955" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Gutiérrez, Dimitri</DisplayName> <Person id="rp03890" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Saldarriaga, Maritza S.</DisplayName> <Person id="rp03953" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Sanders, Christian J.</DisplayName> <Person id="rp03954" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Springer Science and Business Media LLC</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>depositioN</Keyword> <Keyword>Biogeochemistry</Keyword> <Keyword>concentration (composition)</Keyword> <Keyword>concentration (composition)</Keyword> <Keyword>degradation</Keyword> <Abstract>A tropical mangrove forest in Northern Peru was studied to determine if physical and biogeochemical characteristics of creek water and subtidal sediments are related to the seasonal hydrological regimes.
