Evaluation of photosynthetic pathways of vegetation, and of sources of sedimentary organic matter through C in Terminos Lagoon, Campeche, México

Evaluation of photosynthetic pathways of vegetation, and of sources of sedimentary organic matter through C in Terminos Lagoon, Campeche, México

SUBMERGED VEGETATION WAS ISOTOPICALLY CHARACTERIZED IN ORDER TO DETERMINE THE PHOTOSYNTHETIC MECHANISM USED BY EACH SPECIES AND ITS ADAPTATION TO A TROPICAL LAGOONAL ENVIRONMENT OF VARIABLE SLAINITY. ISOTOPIC COMPOSITION FOR THALASSIA TESTUDINUM OF -11.6 TI 15.9 AND DICTYOTA SP OF -16.8 TO 18.7 WAS REGISTERED. FOR HALODULE WRIGHTII AND THE RED ALGAE TWO INTERVALS WERE REGISTERED: H. WRIGHTYY FROM 15.2 TO 17.0 TO THE NORTHEAST OF THE LAGOON AND FROM -23.6 TO 27.6 THROUGHOUT THE REST OF THE SYSTEM, AND THE RED ALGAE OF -17.2 ON THE SUBLITTORAL (BAHAMITA) AND FROM -23.3 TO 27.1 WITHIN THE LAGOON. THE REGISTRATION OF THE TWO INTERVALS OF ISOTOPICA VALUES FOR THESE LAST TWO TYPES OF VEGETATION, THE MANNER IN WHICH THESE INTERVALS ARE RELATED TO THE DISTRIBUTION OF THE VEGETATION WITHIN THE SYSTEM AND TO THE ENVIRONMENTAL CHARACTERISTICS OF EACH LOCALITY, AND THE IMPLICATIONS WITH RESPECT TO PHOTOSYNTHESIS, ARE DISCUSSED. SURFACE SEDIMENT AND DETRITUS WERE ISOTOPICALLY CHARACTERIZED IN ORDER TO IDENTIFY THE NATURAL SOURCES OF ORGANIC CARBON AND ITS DISTRIBUTION WITHIN THE LAGOON. A CLUSTER ANALYSIS WAS APPLIED TO HYDROLOGICAL, SEDIMENTARY AND ISOTOPIC DATA TO DEFINE GROUPS OF SIMILAR LOCALITIES. THE LAGOON WAS DIVIDED INTO TWO AREAS: AREA 1 TO THE NORTH AND NORTHEAST WITH AN AVERAGE δ13C-15.5‰ WHICH INDICATES THAT THE ORGANIC MATTER OF SEAGRASS AND ALGAE BEDS IS THE SOURCE OF ORGANIC CARBON, AND AREA 2, THE REST OF THE SYSTEM WITH AN AVERAGE δ13C OF -20.3‰ THAT INDICATES A PREDOMINANCE OF ORGANIC CARBON OF TERRESTRIAL ORIGIN.

LA VEGETACIÓN SUMERGIDA SE CARACTERIZO ISOTOPICAMENTE CON EL OBJETO DE RECONOCER EL MECANISMO FOTOSINTÉTICO UTILIZADO POR LA VEGETACIÓN Y SU ADAPTACIÓN A UN MEDIO LAGUNAR TROPICAL DE SALINIDAD VARIABLE. LA COMPOSICIÓN ISOTÓPICA VARIO POCO PARA THALASSIA TESTUDINUM DE -11 6 A -15.99 Y DICTYOTA SP. DE -16.8 A-18.7. PARA HALODULE WRIGHTII Y LAS ALGAS RODÓFITAS SE REGISTRARON DOS INTERVALOS AL NOROESTE DE LA LAGUNA Y EN EL RESTO DEL SISTEMA, Y LAS RODÓFITAS EN EL SUBLITORAL (BAHAMITA) Y DE -23.3 A -27.1 DENTRO DE LA LAGUNA. SE DISCUTEN EL REGISTRO DE LOS DOS INTERVALOS DE VALORES ISOTÓPICOS PARA LOS DOS ÚLTIMOS TIPOS DE VEGETACIÓN, LA RELACIÓN DE LOS INTERVALOS CON LA DISTRIBUCIÓN DE LA VEGETACIÓN EN EL SISTEMA Y CON LAS CARACTERÍSTICAS AMBIENTALES DE CADA LOCALIDAD, Y SU IMPLICACIÓN A NIVEL FOTOSINTÉTICO. EL DETRITO Y SEDIMENTO SUPERFICIAL SE CARACTERIZARON ISOTOPICAMENTE PARA DETERMINAR LAS FUENTES NATURALES DE LOS APORTES DE CARBONO ORGÁNICO Y LA DISTRIBUCIÓN DE ESTE EN EL SISTEMA LAGUNAR. SE APLICO UN ANÁLISIS DE CONGLOMERADOS CON LOS HIDROLÓGICOS, SEDIMENTARIOS E ISOTÓPICOS PARA DETERMINAR AGRUPACIONES DE LOCALIDADES SIMILARES. LA LAGUNA SE DIVIDIÓ EN DOS ÁREAS: AREA1, AL NORTE-NORESTE CON LO CUAL INDICA QUE LA MATERIA ORGÁNICA DE LAS PRADERAS DE PASTOS Y ALGAS CONSTITUYE LA FUENTE DE CARBONO ORGÁNICO: ÁREA 2, EL RESTO DEL SISTEMA CON QUE REFLEJA LA PREDOMINANCIA DEL CARBONO ORGÁNICO DE ORIGEN TERRESTRE.
