Forskningsöversikt (refereegranskat)abstract
- This review presents how the boreal and the tropical forests affect the atmosphere, its chemical composition, its function, and further how that affects the climate and, in return, the ecosystems through feedback processes. Observations from key tower sites standing out due to their long-term comprehensive observations: The Amazon Tall Tower Observatory in Central Amazonia, the Zotino Tall Tower Observatory in Siberia, and the Station to Measure Ecosystem-Atmosphere Relations at Hyytiäla in Finland. The review is complemented by short-term observations from networks and large experiments.The review discusses atmospheric chemistry observations, aerosol formation and processing, physiochemical aerosol, and cloud condensation nuclei properties and finds surprising similarities and important differences in the two ecosystems. The aerosol concentrations and chemistry are similar, particularly concerning the main chemical components, both dominated by an organic fraction, while the boreal ecosystem has generally higher concentrations of inorganics, due to higher influence of long-range transported air pollution. The emissions of biogenic volatile organic compounds are dominated by isoprene and monoterpene in the tropical and boreal regions, respectively, being the main precursors of the organic aerosol fraction.Observations and modeling studies show that climate change and deforestation affect the ecosystems such that the carbon and hydrological cycles in Amazonia are changing to carbon neutrality and affect precipitation downwind. In Africa, the tropical forests are so far maintaining their carbon sink.It is urgent to better understand the interaction between these major ecosystems, the atmosphere, and climate, which calls for more observation sites, providing long-term data on water, carbon, and other biogeochemical cycles. This is essential in finding a sustainable balance between forest preservation and reforestation versus a potential increase in food production and biofuels, which are critical in maintaining ecosystem services and global climate stability. Reducing global warming and deforestation is vital for tropical forests.

Aroma-Active Compounds of Capsicum Chinense Var. Biquinho

- Capsicum chinense var. Biquinho presents a strong aroma without the burning pepper sensation. Headspace volatile compounds were isolated by SPME and analyzed by GC-FID, GC-MS, and GC-O. The major compounds profile showed similarity to the profile of spicier peppers, but several minor compounds presented high importance to Biquinho’s characteristic flavor. Aromagram showed 72 compounds; where α-cardinol, heptylisopentanoate, p-xylene, isohexanol, hexyl butanoate, and (Z)-3-hexenyl pentanoate may be potential markers for the sweet and mild pepper flavor of Biquinho. In future, genetic materials of other chili peppers may have crosses with this pepper, which will improve their sensory characteristics.

Volatile Profile of New Improved Brazilian Capsicum chinense Peppers

Bokkapitel (refereegranskat)abstract
- Brazilian geneticists are developing aromatic peppers that, besides their burning sensation, can also add flavor to foods. In this work, the volatile profiles of two new genotypes, CNPH 3931 and CNPH 4080, were compared to the profile of Orange Biquinho pepper, a very scented but not pungent Brazilian variety. Headspace volatile compounds were isolated by SPME and identified by GC-MS. The new genotypes presented very similar volatile profiles, with fewer compounds but higher volatile quantity when compared to Biquinho. They lack some important compounds to Biquinho’s aroma, but the presence of other esters can add a variety of desirable notes. These CNPH peppers were shown to be promising materials.
