The estimation of carbon accumulation in restoration areas over time is an important step for the evaluation of the success of restoration programs and to indicate the best practices for forest management and conservation. In the present study, we evaluated the aboveground biomass (AGB) of 10 tree species (fast-growing and slow-growing tree species) that are representative of the Brazilian Atlantic forest to test if biomass accumulation varies with tree age and ecological group (fast- and slow-growing). We also used regression models to simulate how much carbon is sequestered over time in restoration areas of tropical wet forests. The results exhibited differences between the two groups in terms of biomass accumulation; the slow-growing species accumulated an almost two-fold higher amount of total biomass (379.4 kg) than the fast-growing species (208.56 kg). The estimated age of the individuals explained the biomass accumulation: the long-lived and slow-growing species accumulate less biomass over a longer time, and the short-lived fast-growing species accumulate more biomass over a shorter period. These differences suggest that the fast-growing tree species contribute more to the carbon stock during the early years (approximately 37 years) of the restoration and that the slow-growing species contribute more significantly during the later stages of succession. We estimated that second-growth forests (41? 60 years old) accumulate more than two-fold carbon than immature forest (21?40 years old) and much more than ten-fold carbon than young forests (7?20 years old). These differences in carbon sequestration magnitudes suggest that services provided by restoration areas, can increase exponentially in the first 60 years, and this is particularly important for future conservation and management of areas undergoing restoration.

Five different concentrations of golden flaxseed flour (0%: F0 (control), 5%: F1, 10%: F2, 15%: F3, 20%: F4) were used as a functional ingredient to replace the fat in chicken burgers. The products were analyzed for moisture, protein, carbohydrate, fat, ash, shear force, consumer acceptance, and their sensory and technological characteristics. The fat, carbohydrate, and protein contents of the raw hamburgers did not differ significantly. An increase in golden flaxseed flour concentration caused a decrease in moisture content and an increase in ash content. The addition of golden flaxseed flour positively affected the technological characteristics and increases in the yield and water retention capacity were observed, together with decreases in shrinkage and mechanical resistance. Formulation F1 presented the highest average acceptance, which did not differ from the F0, and the latter also did not differ from F2. The F3 and F4 formulations differed from the others, with lower average values for acceptance. The check-all-that-apply method revealed that the formulations F0, F1, and F2 were described by sensory terms that corresponded to the desired sensory characteristics. The addition of golden flaxseed flour improved the technological characteristics and the biofunctional potential arising from its bioactive compounds, making it an option as an ingredient for meat products. |
