Epiphyte diversity in Irish conifer plantations
(Trinity College (Dublin, Ireland). Department of Botany, 2007)Government policy aims to increase the area under forestry in Ireland from its current 10% to 17% by 2030. Baseline information on the biodiversity of these forestry plantations is required if they are to be effectively ... -
The palaeoecology of Clara Bog, Co. Offaly
(Trinity College (Dublin, Ireland). Department of Botany, 2000)This thesis contains the results of an investigation into the palaeoecology of a midlands raised bog, Clara Bog, Co. Offaly. It was undertaken to investigate the development of the bog and some of its features. The thesis ... -
Multi-proxy evidence from bogs for environmental change in Ireland over the last 1,200 years
(Trinity College (Dublin, Ireland). Department of Botany, 2001)In order to understand recent and future climate change, it is necessary to document how climates have varied in the past. Literature and research concerning climate change of the last 1,200 years, namely the Medieval Warm ... -
Micropropagation of ash (Fraxinus excelsior L.)
(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
(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
(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
(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
(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
(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

Phylogenetic analysis of Papaver L.
(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
(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 ... -
Thank you for not flowering: conservation genetics and gene flow analysis of native and non-native populations of Fraxinus (Oleaceae) in Ireland
(2014)The risks of gene flow between interfertile native and introduced plant populations are greatest when there is no spatial isolation of pollen clouds and phenological patterns overlap completely. Moreover, invasion probabilities ... -
Bumblebees are not deterred by ecologically relevant concentrations of nectar toxins.
(2014)Bees visit flowers to collect nectar and pollen that contain nutrients and simultaneously facilitate plant sexual reproduction. Paradoxically, nectar produced to attract pollinators often contains deterrent or toxic plant ... -
Ecology and mode-of-life explain lifespan variation in birds and mammals.
(2014)Maximum lifespan in birds and mammals varies strongly with body mass such that large species tend to live longer than smaller species. However, many species live far longer than expected given their body mass. This may ... -
Interannual variation in nitrous oxide emissions from perennial ryegrass/white clover grassland used for dairy production.
(2014)Nitrous oxide (N2 O) emissions are subject to intra- and interannual variation due to changes in weather and management. This creates significant uncertainties when quantifying estimates of annual N2 O emissions from grazed ... -
Agricultural policies exacerbate honeybee pollination service supply-demand mismatches across europe.
(2014)Declines in insect pollinators across Europe have raised concerns about the supply of pollination services to agriculture. Simultaneously, EU agricultural and biofuel policies have encouraged substantial growth in the ...
