  abstract = {{B}y definition 'ecosystem engineers' are those organisms capable to modify physically the environment by producing 'biogenic' structures ({BS}). {L}arge macroinvertebrates like termites, earthworms and ants produce {BS} with distinguishable physico-chemical properties. {W}e measured total {C}-org, {NH}4+ and {NO}3- contents in the {BS} produced by two species of {N}eotropical termites (subfamily {N}asutermitinae) in a gallery forest ({GF}) of the {E}astern {P}lains of {C}olombia. {W}e sampled from the top of the {BS} to the edge at proportional distances, i.e. 20-100% for the largest {BS} in the soil surface and 50-100% for the smallest arboricole {BS}. {C}ontrol soil was sampled {I} m apart from the {BS}. {V}alues of total {C}-org were high in the {BS} produced by {N}asutitermes sp1 (epigeic mound), while a high {N} mineralization process was observed in the same {BS} and in the {N}asutitermes sp2 arboreal nest. {T}he role of these two ecosystem engineers in nutrient cycling is discussed.
