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.

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

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
