| description | Riparian soils are recognized as important regions of long-term carbon storage. However, different hydromorphological factors along riparian gradients, as well as land use, can influence the distribution and concentration of soil organic carbon (SOC). The objective of this study was to evaluate the concentrations of SOC in catenas of riparian soils and to characterize soil organic matter (SOM) at the micromorphological level in three riparian ecosystems of Iztaccihuatl volcano (grasslands, forests, and agricultural zone). At each site, disturbed and undisturbed samples were collected in soil profiles along a catenary perpendicular to the stream. In the laboratory, COS was determined in the fine soil fraction and soil organic matter (SOM) micromorphology was described in thin sections. COS varied according to vegetation and land use (grassland 38.95 kg m-2 > forest 34.40 kg m-2 > agricultural zone 17.77 kg m-2). The highest values in COS occur in soils closer to the stream up to 68.92 kg m-2. SOM presents different organic residues and stages of decomposition and with higher abundance in the riparian subsoil where hydromorphism conditions limit its mineralization. Riparian soils have a greater potential to accumulate carbon (halophytic and autochthonous) than adjacent uplands. Likewise, degradation of these ecosystems has an impact on carbon storage and their role in climate change mitigation. |

Los suelos ribereños se reconocen como regiones importantes de almacenamiento de carbono. Sin embargo, los diferentes factores hidromorfológicos de los gradientes ribereños, así como el uso del suelo, pueden influir en la distribución y concentración de carbono orgánico del suelo (COS). El objetivo de este estudio fue evaluar las concentraciones de COS en catenas de suelos ribereños y caracterizar la materia orgánica del suelo (MOS) a escala micromorfológica en tres ecosistemas ribereños del volcán Iztaccíhuatl (pastizales, bosques y zona agrícola). En cada sitio se colectaron muestras alteradas e inalteradas en perfiles de suelos en una catena perpendicular a la corriente. En el laboratorio se determinó el COS en la fracción de tierra fina y se describió la micromorfología de la MOS en secciones delgadas. El COS varió de acuerdo con la vegetación y el uso de suelo (pastizal 38.95 kg m-2 > bosque 34.40 kg m-2 > zona agrícola 17.77 kg m-2). Los valores más altos de COS ocurren en los suelos más cercanos a la corriente hasta 68.92 kg m-2. La MOS presenta diferentes residuos orgánicos y etapas de descomposición y con mayor abundancia en el subsuelo ribereño donde las condiciones de hidromorfismo limitan su mineralización. Los suelos ribereños tienen un mayor potencial para acumular carbono (halóctono y autóctono) que las tierras altas adyacentes. Asimismo, la degradación de estos ecosistemas repercute en el almacenamiento de carbono y en su papel en la mitigación del cambio climático.
