This study used radiation and weather data obtained from a SONDA BSRN radiation station, as well from a flux tower installed in the study area; both were near the urban areaofPetrolina, Brazil. Furthermore, radio-sounding data collected nearby were employed to obtain column integrated atmospheric water vapour, to estimate atmospheric emissivity. |

Litterfall quantity and quality may respond to alterations in resource availability expected with ongoing land-use and climate changes. Here, we quantify the effects of altered resource availability on non-woody litterfall quantity and quality (nitrogen and phosphorus concentrations) in easternAmazonian forest regrowth (Brazil) through twomulti-year experimentalmanipulations: (1) daily irrigation (5mmd?1) during the dry season; and (2) fortnightly litter removal. Consistentwith other tropical forest data litterfall exhibited seasonal patterns, increasingwith the onset of the dry season and declining with the onset of the rainy season. Irrigation did not affect litterfall mass and had little impact on nitrogen (N) or phosphorus (P) concentrations and return, except for decreasing litter P concentration at the end of two irrigation periods. Litter removal did not alter litterfall mass or P concentration, but progressively reduced litterfall N during the course of the experiment. Overall, these results suggest signi?cant resistance to altered resource availabilitywithin the bounds of our experimental treatments; our ?ndingsmay help to constrain carbon and nutrient cycling predictions for tropical forests in response to land-use and climate changes |
