dc.description	El presente estudio se desarrollo como una auxilia de investigación en el marco del macroproyecto “Relación hormigas arrieras y servicios ecosistémicos del suelo en el humedal El Charco-Oasis, Villavicencio, Meta”. El trabajo contribuyo al análisis de la posible influencia de la hormiga arrieras cortadoras de hoja sobre algunas propiedades fiscas e hidrológicas del suelo en el humedal urbano El Charco-Oasis, ecosistema relevante para la regulación ambiental y conservación de la biodiversidad. Se realizó el muestreo y análisis del suelo en zonas con y sin presencia de hormigas, se evaluaron variables como humedad gravimétrica, porosidad, textura y estabilidad estructural, mediante el porcentaje de agregados estables al agua (%EAA) y el diámetro medio ponderado (DMP). Estos indicadores permitieron explorar posibles variaciones asociadas a la actividad de excavación, remoción y redistribución de partículas. Los resultados permitieron identificar tendencias descriptivas relacionadas con diferencias en algunas propiedades físicas, particularmente en la heterogeneidad espacial de la porosidad y en indicadores de estabilidad estructural. Sin embargo, la prueba exacta bilateral de Mann- Whitney no evidencio diferencias estadísticas significativas entre los grupos evaluados (p > 0,05). Debido al carácter exploratorio y al tamaño limitado de la muestra, los resultados deben interpretarse como asociaciones y no como evidencia de causalidad. En este sentido, el estudio aportó una aproximación al posible papel de la bioturbación de las hormigas arrieras en la organización física del suelo y destacó la importancia de profundizar en estas interacciones mediante diseños experimentales más robustos. Los resultados constituyeron una base para futuras investigaciones orientadas al manejo, conservación y restauración de humedales urbanos.
dc.description.abstract	This study was conducted as a research auxiliary within the framework of the macro-project “Relationship between leafcutter ants and soil ecosystem services in the El Charco-Oasis wetland, Villavicencio, Meta.” The work contributed to the analysis of the potential influence of leafcutter ants on some physical and hydrological properties of the soil in the El Charco-Oasis urban wetland, an ecosystem relevant for environmental regulation and biodiversity conservation. Soil sampling and analysis were carried out in areas with and without the presence of ants. Variables such as gravimetric moisture, porosity, texture, and structural stability were evaluated using the percentage of water-stable aggregates (%WSA) and the weighted average diameter (WAD). These indicators allowed for the exploration of possible variations associated with the burrowing, removal, and redistribution of soil particles. The results allowed for the identification of descriptive trends related to differences in some physical properties, particularly in the spatial heterogeneity of porosity and in indicators of structural stability. However, the two-tailed Mann-Whitney U test did not reveal statistically significant differences between the evaluated groups (p > 0.05). Due to the exploratory nature of the study and the limited sample size, the results should be interpreted as associations and not as evidence of causality. In this sense, the study provided an approximation of the possible role of leafcutter ant bioturbation in the physical organization of the soil and highlighted the importance of further investigating these interactions through more robust experimental designs. The results provided a basis for future research focused on the management, conservation, and restoration of urban wetlands.
