    • Micropropagation of ash (Fraxinus excelsior L.) 

      Abbott, Jane I. E. (Trinity College (Dublin, Ireland). Department of Botany, 2005)
      Ash (Fraxinus excelsior L.) is a native hardwood species in Ireland used as a fast growing tree that is well adapted to agricultural sites. It produces wood valued for its toughness and elasticity. A key objective for Its ...

    • The contribution of nitrous oxide emissions from Irish agriculture to global warming 

      Abdalla, Mohamed F. (Trinity College (Dublin, Ireland). Department of Botany, 2007)
      Results from this thesis concern the calculation of annual fluxes and emission factors of the greenhouse gas nitrous oxide from two agricultural soils in Co. Carlow, Ireland. For a cut and grazed pasture in 2004, the annual ...

    • Plant and snail communities in three habitat types in a limestone landscape in the west of Ireland, and the effects of exclusion of large grazing animals 

      Long, Maria P. (Trinity College (Dublin, Ireland). Department of Botany, 2011)
      This thesis documents the plant and snail communities found in woodland, scrub and grassland in the Burren region in the west of Ireland. The flora of the Burren is renowned and has been well ­studied, but the vegetation ...

    • Phosporous dynamics of grazed grassland in Ireland 

      Bourke, David (Trinity College (Dublin, Ireland). Department of Botany, 2008)
      The loss of phosphorus (P) from agricultural sources is one of the main causes of eutrophication in P limited freshwater ecosystems. High losses have been shown from grazed grasslands in particular. The aim of this ...

    • Large trees, supertrees and the grass phylogeny 

      Salamin, Nicolas (Trinity College (Dublin, Ireland). Department of Botany, 2003)
      During the last decade, the advances of molecular techniques have profoundly changed the way scientists build and use phylogenetic trees. Vast fields of research as different as ecology, evolution of development, genomics, ...

    • The vegetation ecology and native status of Scots pine (Pinus sylvestris L.) in Ireland 

      Roche, Jennifer (Trinity College (Dublin, Ireland). Department of Botany, 2010)
      This thesis examines the vegetation ecology, native status and biodiversity value of Scots pine (Pinus sylvestris L.) in Ireland, using a variety of biogeographical, palaeoecological and ecological approaches at different ...

    • A systematic revision of the Santalaceae R. Br. of Southeast Asia 

      Macklin, Jill (Trinity College (Dublin, Ireland). Department of Botany, 2001)

    • Phylogenetic analysis of Papaver L. 

      Carolan, James C. (Trinity College (Dublin, Ireland). Department of Botany, 2004)
      The phylogenetic relationships of Papaver L. were investigated using morphological, molecular and phytochemical characters. Such information is of great utility because Papaver species produce highly valuable secondary ...

    • Grass-evolution and diversification : a phylogenetic approach 

      Bouchenak-Khelladi, Yanis (Trinity College (Dublin, Ireland). Department of Botany, 2007)
      The growth in size of phylogenetic trees, over the last 20 years, has allowed evolutionary biologists to better test hypotheses about the evolutionary history of organisms, and especially those of species rich taxa such ...
