1. 1. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

   University essay from Högskolan i Gävle/Samhällsbyggnad

   Author : Mathias Billenberg; [2023]
   Keywords : TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

   Abstract : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. READ MORE

3. 2. Advancing understanding of tropical forest carbon dynamics through improved allometric models for palms: A case study with Prestoea montana in Puerto

   University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Paschalis Chatzopoulos; [2021]
   Keywords : Above ground biomass; allometry; Luquillo Forest Dynamics Plot; Palms;

   Abstract : Tropical forests are major components of Earth’s carbon stocks, but their diversity and structural complexity pose major challenges for making accurate estimates of their above ground biomass (AGB). Palms, in particular, are prominent and unique components of many tropical forests that have anatomical and physiological differences from dicot trees which affect their height - diameter allometry and consequently, our ability to accurately estimate their AGB.

4. 3. A detailed study on Amazon Forest structure and mortality rates through LPJ-GUESS vegetation model

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Sara Mazzuoli; [2021]
   Keywords : Amazon s Forest; LPJ-GUESS; simulation; TEAM-NETWORK; dynamic vegetation model; observation; mortality; allometry; tree stand structure; biomass; cohort; PFTs; plant functional types; NPP; Earth and Environmental Sciences;

   Abstract : Nowadays it has become relevant for scientists to understand the impact of tropical forest structure on the Global Carbon Cycle. Dynamic vegetation models have been developed to pursue this issue, specifically by improving algorithms that could analyze the allometry, biomass content and mortality rate of each singular simulated plant individual and how this responds to climate change, management and rising CO2 concentrations.

5. 4. Increased Drought and Fire Intensity Regimes Reduce the Ecological Resilience of Mediterranean Forests in the South-West Australian Floristic Region

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Shareen Sanders; [2020]
   Keywords : Allometric models; Above-ground biomass AGB ; drought; fire; disturbance; understorey; resilience; Mediterranean.;

   Abstract : Future climate projections suggest an increase in average temperature as well as a decrease in average winter rainfall across the south-west Australian floristic region (SWAFR). These adverse future climatic conditions will amplify the intensity and frequency of disturbance events such as drought and fire. READ MORE

6. 5. Measuring carbon sequestration and soil fertility in Swedish forest gardens : a methodological study

   University essay from SLU/Dept. of Soil and Environment

   Author : Elsa Lagerquist; [2016]
   Keywords : biomass production; allometric equations; soil science; carbon cycling; agroforestry;

   Abstract : Agroforestry is an old agricultural practice which has got renewed interest during the last decades as an alternative to industrialized agriculture. Agroforestry is a practice with potential to promote several ecosystem services, e.g. carbon seques-tration and soil improvement. READ MORE
