(Trinity College (Dublin, Ireland). Department of Botany, 2001)The reported failure of regeneration in British oakwoods and some observations of a dearth of saplings and young trees in Irish woods has prompted concerns about the ability of Irish semi-natural woodland to self-perpetuate. ... -
The effects of elevated CO2 and water stress on C2 pasture species (Blepharis linariifolia and Cenchrus biflorus) native to Sudan
(Trinity College (Dublin, Ireland). Department of Botany, 2001)A doubling of the pre-industrial atmospheric CO2 concentration (~280 ppmv) is expected by the middle of this century, if the current rate of growth in the annual emission of fossil carbon is maintained. The effects of ... -
