Phytogeography and the stoichiometric niche: exploring their interplay in Sulawesi
The Indonesian island of Sulawesi is comprised of a mosaic of soil types including the largest ultramafic outcrops in the tropics (ultramafic soils are macronutrient low and phytotoxic heavy metal rich). The island’s ontogeny is also distinctive, whereby it has formed only recently < 2 million years ago via agglomeration...Trethowan, Liam A.

Automating the construction of higher order data representations from heterogeneous biodiversity datasets
Datasets created from large-scale specimen digitisation drive biodiversity research, but these are often heterogeneous: incomplete and fragmented. As aggregated data volumes increase, there have been calls to develop a “biodiversity knowledge graph” to better interconnect the data and support meta-analysis, particularly relating to the process of species description. This work...Nicolson, Nicky

Taxonomy, evolutionary history, and ecological dominance of Themeda and Heteropogon.
Heteropogon and Themeda grasses are common and significant components of the C4 savannas which have recently gained more attention for conservation and biodiversity research. The two genera have been the subject of ecological research due to their widespread and dominant species H. contortus and T. themeda. Like many tropical plant...Arthan, Watchara

Molecular and Genome Evolution in the Malesian Slipper Orchids (Paphiopedilum section Barbata).
Paphiopedilum section Barbata (Cypripedioideae: Orchidaceae) is an evolutionarily young and charismatic group of terrestrial orchids native to the Himalayas, Indochina and Malesia. It contains several interesting species complexes, variable chromosome numbers (2n=28-42) and genome sizes (2C=55-70 pg) with hybrid speciation suspected on the basis of morphological data. In Chapter 1,...Yap, Jing Wei

Conservation genetics and biogeography of the Caribbean pine (Pinus caribaea var. bahamensis) in the Bahaman archipelago.
The Bahaman archipelago contains large expanses of pine forests, where the endemic Caribbean pine Pinus caribaea var. bahamensis is the dominant species. This pine forest ecosystem is rich in species and also a valuable resource for the local economy. Small areas of old-growth forest still remain in the Turks and...Sanchez, Michele

Boraginaceae Varronia rupicola (Urb.) Brtton : biogeography, systematic placement and conservation genetics of a threatened species endemic to the Caribbean.
In the Caribbean region, Varronia rupicola (Boraginaceae) is a medium to large, woody shrub endemic to the Puerto Rican Bank where it is threatened with extinction due to its limited area of occupancy, small populations and on-going threats. The greatest of these is currently loss of suitable habitat through development...Hamilton, Martin Allen

Molecular ecology and conservation of Mediterranean orchids and their mycorrhizal fungi.
The distribution and abundance of orchid mycorrhizal fungi (OMF) can influence the the establishment and resulting spatial pattern, as well as the population dynamics, of their host plants. Yet, our understanding of these mycorrhizal associations is currently limited by our restricted knowledge of the ecology and spatial distribution of OMF,...Calevo, Jacopo

Species integrity and hybridization in anthropomorphic Orchis species (Orchidaceae).
Hybridization is widespread in Orchis (Orchidaceae), with 38 recorded hybrids between the 21 accepted species. The four anthropomorphic Orchis species that occur in Britain (O. anthropophora, O. militaris, O. purpurea and O. simia) are on the edge of their range and are of high conservation priority. Understanding how these species...Bersweden, Leif

Plant conservation in space, time and a changing world: forecasting the fate of Coffea arabica in Ethiopia.
We are facing an ever-increasing environmental crisis on our planet, with multiple threats from humankind. Industrialisation, deforestation, overpopulation and exploitation of our natural resources is driving species to extinction and changing the environment we live in. We need to plan for the future in order to adapt or mitigate these...Moat, Justin

Heterogeneous cloth: an ethnography of the coming into being of barkcloth artefacts at the Royal Botanic Gardens, Kew, and amongst the Nuaulu of Nua Nea Village, Maluku, Eastern Indonesia.
5. Abstract This thesis uses barkcloth artefacts as a methodological point of entry and fieldsite, to explore their material properties. It argues that the material properties of barkcloth artefacts are indexical of social relations, as it moves between contexts; exploring the nature of properties as inherently diverse or diversely exploited,... -

Taxonomy and systematics of Urophyllum (Rubiaceae) in Thailand and Indochina.
The genus Urophyllum Wall. is a taxonomically problematic genus of Rubiaceae in Thailand due to the lack of a recent taxonomic revision and identification key to the species. This has led to confusion in the identification of species and no conservation status assessments for the genus. The aim of this...Yooprasert, Sawita

Phylogenetics and characterisation of Lamiaceae tribe Ocimeae, subtribe Ociminae.
Phylogenetic analyses of the subtribe Ociminae (Lamiaceae) based on four plastid DNA regions (trnL–trnF intergenic spacer, trnH-psbA intergenic spacer, matK and rps16 intron) and two nuclear DNA regions (ITS and ETS) are presented. Bayesian inference was utilized for the reconstruction of phylogenies and for the assessment of statistical support for...Althobaiti, Ashwaq T.

Fungal interactions with vascular and non-vascular plants: an investigation of mutualisms and their roles in heathland regeneration.
Mycorrhizal mutualisms between aboveground vascular plant communities, which reward their belowground fungal associates with photosynthates in return for growth-limiting nutrients such as phosphate, are widely recognized as stable long-term interactions which helped plants colonize land. Pezoloma ericae (D.J. Read) Baral, an ascomycete mycorrhiza-forming fungus present amongst plants in the Ericales,...Kowal, Jill
