Doctoral thesis
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
