  1. 1. Studying gene expression scaling with cell size in Arabidopsis thaliana : the role of the nuclear RNA exosome complex

    University essay from SLU/Dept. Of Plant Biology

    Author : Emily Tåhlin; [2024]
    Keywords : RNA; transcription; cell size; smFISH; Arabidopsis thaliana;

    Abstract : The scaling of organ size with body size - known as morphological allometry - is a fundamental mechanism observed in all organisms (Mirth et al. 2016). READ MORE

  3. 2. Drivers of flower size evolution in the selfing species Arabidopsis thaliana

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Clàudia Fernández Mestre; [2023]
    Keywords : Arabidopsis thaliana; petal size; fitness; selection; evolutionary drivers; GWAS;

    Abstract : The influence of pollinators on the evolution of flower morphology has been extensively explored. Yet, the effect of other ecological factors, such as genetic drift, environmental filtering, and allometric constraints, gained less attention. In this study, we addressed the importance of those drivers in a predominantly selfing species. READ MORE

  4. 3. 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.

  5. 4. 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.

  6. 5. Estimating above ground biomass in a Salix plantation using high resolution UAV images

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Simon Nåfält; [2018]
    Keywords : biomass; Salix; structure from motion; unmanned aerial vehicle; allometry; point cloud; Earth and Environmental Sciences;

    Abstract : In forest biomass estimations, three dimensional (3D) canopy structure data derived from images captured by unmanned aerial vehicles (UAVs), also known as drones, has shown potential due to the flexibility and cost efficiency of the method. However, little research has been done for its applicability in bioenergy forest. READ MORE
