  1. 1. Short-Time Temporal Changes of CH4 Fluxes in Different Tropical Tree Species : In-situ research regarding methane emissions from inundation-adapted Amazonian tree species in Jardim Bot�nico do Rio de Janeiro.

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Emelie Athley; [2023]
    Keywords : Methane CH4 ; environment; greenhouse gas GHG ; emission; Amazonian tree species; tropical trees; wetland; flux; CH4 emission from plants; tree mediated CH4 emission; Global CH4 budget; environmental stressors; meteorological parameters; natural CH4 emissions;

    Abstract : Methane (CH4) is guaranteed to affect climate change and is essential in rising temperatures. Scientists have known for over two decades that wetlands emit CH4 to such an extent that it affects our climate. Tropical trees that grow in wetlands tend to emit or act as a conduit of CH4, to the extent that it has a negative environmental impact. READ MORE

  3. 2. Methane tree stem flux over the course of the spring flood : Spatial and temporal effects in a boreal riparian zone

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Elin Berg; [2022]
    Keywords : Methane; tree stem flux; boreal forest; riparian zones; spring flood;

    Abstract : Methane (CH4) tree stem-atmosphere flux is viewed as a new frontier in the global carbon cycle and may be of great importance. The effect on flux from different tree species, forest ecosystems and seasons is still uncertain. READ MORE

  4. 3. Methane fluxes from tree stems in Amazon floodplains : Evaluating methodological aspect of measuring spatial and seasonal variability in a flooded system

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : felicia Widing; Nina Rubensson; [2018]
    Keywords : CH4; Tree stems; Amazon floodplain forest; Wetlands; flux; Solimões; Negro; Tapajós;

    Abstract : Träd i tropiska våtmarker har uppmärksammats som en viktig källa till regionala och globala metan (CH4) utsläpp, då träd fungerar som utsläppskanaler för metan som bildas i sedimenten. Dock finns det en osäkerhet gällande säsongsvariation och rumslig variation samt mängden CH4 utsläpp från träd, eftersom kunskapen kring regionala flöden är begränsad. READ MORE

  5. 4. Integration of LiDAR data and satellite imagery for biomass estimation in conifer-dominated forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Keywords : digital elevation model; vegetation classification; AGB; aboveground biomass; remote sensing; LiDAR; SPOT-5; DEM; canopy height model; CHM; tree segmentation; Earth and Environmental Sciences;

    Abstract : Ett första steg i arbetet att uppskatta kolflödet mellan landbaserade ekosystem och atmosfären är att så precist som möjligt analysera kvantiteten ovanjordisk biomassa. LiDAR teknologi har i detta avseende visat sig vara ett värdefullt verktyg. READ MORE
