  abstract = {{S}oil respiration represents the largest flux of {CO}2 emission from terrestrial ecosystems, being affected by land-use changes and soil properties. {T}here are few studies investigating the response of soil respiration to land-use changes in the {C}aatinga biome. {T}his study aimed to measure soil respiration from {C}aatinga vegetation and degraded pasture, to verify the effect of land-use changes on soil respiration. {M}easurements of soil respiration were performed using the infrared gas analyzer method over nine months (in rainy and dry seasons), in {C}aatinga and degraded pasture in the semi-arid region of {P}ernambuco. {T}he soil moisture, soil temperature, soil organic carbon ({SOC}), {N}ormalized {D}ifference {V}egetation {I}ndex ({NDVI}), and climatic variables were also measured. {S}oil organic carbon and {NDVI} were higher in {C}aatinga than in degraded pasture, while the inverse occurred with soil temperature. {T}he soil respiration showed a clear seasonal variation, with the highest values occurring in the wet season, being positively correlated with soil moisture and negatively with soil temperature. {S}oil respiration was significantly higher in the {C}aatinga (8.0 ton ha(-1) yr(-1) of {C}) than in degraded pasture (3.7 ton ha(-1) yr(-1) of {C}). {T}hese higher values of soil respiration in {C}aatinga were due to lower soil temperature and higher {SOC}, and can be seen as indicators of good environmental quality.},
