Developing a Social Impact Measurement Framework for the UNESCO’s Biosphere Reserve (Cat Ba Archipelago Biosphere Reserve, Viet Nam)
The Biosphere Reserve (BR) seeks to contribute to social sustainability at a global level (UNESCO/MAB, 1996; Ishwaran et al., 2008a). This study develops a Social Impact Measurement Framework (SIMF) for the UNESCO’s BR (through the case study of Cat Ba Archipelago BR, Viet Nam). The SIMF for the BR …

Interactions of the Terrestrial Biosphere With Climate and Atmospheric Chemistry
Isoprenoids are the most dominant class of biogenic volatile organic compounds (BVOCs) and have been shown to significantly impact global tropospheric chemistry and composition, climate and the global carbon cycle. In the second part of this dissertation, the sensitivity of biogenic isoprene and …

Diversity and evolution of ecosystems: From genomes to the biosphere
In this thesis, I present research on biological systems at three different scales of space and time: biodiversity of ecological systems, the dynamics of repetitive elements and their diversity in the genome, and the development of phylogenetic trees in evolution. The unifying theme is the …

Coupling of Integrated Biosphere Simulator to Regional Climate Model version 3
… is a description of the coupling of Integrated Biosphere Simulator (IBIS) to Regional Climate Model version 3 (RegCM3), and an assessment of the coupled model (RegCM3-IBIS). RegCM3 is a 3-dimensional, primitive equation limited area model used throughout the world for seasonal predictability and …

Unraveling the Eco-Evolutionary Complexity of Uncultivated Bacteriophages in the Biosphere
Bacteriophages, or phages, have historically been distinguished by their small sizes and relatively simple genomes compared to cellular life. Discoveries over recent decades, however, have uncovered remarkably large phages, called jumbo phages, which are defined by having genomes over 200 kilobases …

Mobilizing Assets for Sustainable Rural Tourism Development in UNESCO’s Frontenac Arch Biosphere
UNESCO biosphere reserves are internationally recognized as ‘learning places’ for sustainable development. In the Frontenac Arch Biosphere, sustainable tourism has been recognized as a core avenue for sustainable development, with opportunities for tourism operations to promote more sustainable …

Biosphere-atmosphere interaction in a one-dimensional climate model of the tropics
… which includes two way interaction between the biosphere and the atmosphere. The model integrates a radiative-convective equilibrium model of the atmosphere, a land surface model including plant growth and competition and a monsoon circulation model which allows for the exchange of heat and …

Investigating the influence of biosphere-atmosphere interactions on atmospheric chemistry and composition
The interactions between the biosphere and the atmosphere are an important controlling factor for regional to global atmospheric chemistry and composition. This ultimately has wide impacts on issues like air quality and climate change. However, there are still substantial uncertainties in the …

Ground - dwelling arthropods in a biosphere reserve: patterns of diversity and conservation implications
… beetle and millipede diversity in the Vhembe Biosphere Reserve – the largest biosphere reserve in South Africa, and one of the largest in Africa. Firstly we aim to provide an evaluation of the ability of a range of broad and fine scale predictors to explain the variation in the diversity of …

Fruit bat diet, foraging ecology and seed dispersal in the Vhembe Biosphere Reserve.
Agricultural intensification, and a rapid human population growth have resulted in increased human wildlife contact. In the case of fruit bats, conflict with commercial fruit farmers has been a leading contributor to a decline of bat species populations, despite the vital ecosystem service of seed …

Phylogenetic and physiological characterization of deep-biosphere microorganisms in El’gygytgyn Crater Lake sediments
… microbial ecosystems in the deep subsurface – a biosphere that was originally considered devoid of life – was discovered in multiple microbiological studies. However, most of the studies are restricted to marine ecosystems, while our knowledge about the microbial communities in the deep …

Examining the Role of Climate, Carbon and Nitrogen Interactions in the Terrestrial Biosphere
In the second part of this thesis, a comprehensive model of terrestrial nitrogen (N) dynamics is developed and coupled with the geographically explicit terrestrial C cycle model of ISAM. Observations from the Long-term Intersite Decomposition Experiment (LIDET) dataset were compiled for the …

Biosphere-atmosphere exchange of ammonia from a fertilized corn canopy in Central Illinois
Chemical fertilizer use is the primary source of anthropogenic atmospheric NH3 in Illinois. Atmospheric NH3 is a precursor to secondary particulate matter (PM) and it also contributes to eutrophication and soil acidification following wet or dry deposition. Uncertainty in NH3 emissions due to …

Metagenomic approaches for examining the diversity of large DNA viruses in the biosphere
The discovery of large DNA viruses has challenged the traditional perception of viral complexity due to their enormous genome size and physical dimensions. Previously, viruses were considered small, filterable agents until the discovery of large DNA viruses. Among large DNA viruses, the phylum …
