Investigating variation in temperature-related genes in Aspen
Last updated: 19 January 2010
Colin Kelleher (National Botanic Gardens)
Annelies Pletsers (Trinity College Dublin)
Aspen has a wide longitudinal and latitudinal range, and shows variation in bud-burst timing across this range.
This study aims to identify candidate genes related to bud-burst, assessing these for single nucleotide
polymorphisms (SNPs).

Improving the delivery of advice from conservation ecology to REPS
Last updated: 24 July 2009
Matthew Jebb (National Botanic Gardens)
A methodology has been developed to identify areas of high plant diversity in Ireland. Being able to classify farmland as being of High Nature Value, in an objective manner, will allow the distribution of subsidies aimed at environmental protection to be targeted at the most appropriate farms. A preliminary survey has been undertaken for three counties as examples, and an outline of the next steps required to develop a regional or county scale operational model are being developed.

Conservation status and population genetics of the Kerry Lily
Last updated: 8 January 2009
Darach Lupton (National Botanic Gardens)
The Kerry Lily, Simethis planifolia is a protected species in Ireland, only known
from three locations - two in South-West Kerry and one in West Cork. The Irish populations
are the most northerly in Europe, and the species is protected under the Flora Protection Order.
This project aims to assess the conservation status, and genetic diversity of the species.

Eradication of Gunnera tinctoria on Clare Island, Co Mayo.
Last updated: 14 January 2009
Cristina Armstrong (National Botanic Gardens) and Deirdre Cunningham (Mayo County Council) with part funding from the Biodiversity Fund, Heritage Council.
A project to control and eradicate Gunnera tinctoria on Clare Island, based on 3 years of field
trials using the herbicide Glyphosate on Achill Island. The distribution of G. tinctoria has been
mapped on Clare Island, to know the exact location of each population to be treated, and during 2008 the first
eradication measures were undertaken.

A revision of the ant-plant genus Hydnophytum.
Last updated: 8 February 2009
Matthew Jebb (National Botanic Gardens) and Camilla Huxley (Oxford University).
Hydnophytum is the largest of the five genera of 'ant-plants' in the Rubiaceae. These plants are
almost exclusively epiphytic, and develop chambered tubers at the base of their stems, which act as homes
to ants or other creatures - a remarkable symbiotic relationship in which the ant colony gets a home,
and leaves behind detritus that helps to feed the plant.

Floras of the Irish Isles
Last updated: 8 February 2009
Matthew Jebb (National Botanic Gardens).
A literature survey of Irish island floras revealed a correlation between the log of the
island’s area to the log of species richness. These island floras conformed to a regression
line, which indicated that with every doubling in area, an Irish island’s floral diversity increases by ca. 3.4 %.

The vascular flora of Lambay
Last updated: 8 February 2009
Matthew Jebb (National Botanic Gardens).
Lambay is an island lying some four kilometres off the east coast of county Dublin.
Two previous publications have dealt with the vascular flora of Lambay, in 1883 and 1907.
The results of this resurvey demonstrate major changes in the vegetation and species.
309 vascular plant taxa are presently recorded as naturalised on Lambay, 78 previously recorded species were not
refound, while 54 taxa have been recorded for the first time.

Phylogeny and biogeography of the genus Nepenthes
Last updated: 8 February 2009
Josef Mullins (Reading University), Matthew Jebb (National Botanic Gardens).
molecular data sets from the chloroplast (trnL – trnF) and nuclear genome (5S-NTS)
were analysed to investigate phylogenetic relationships within the family.
The two gene trees indicated incongruence of a number of taxa (15 taxa). The analysis
suggests a circum-Indian Ocean origin for the genus with a highly conserved and
relictual basal clade, and a recent and rapid expansion from New Guinea westwards into South-East Asia.
There is no evidence for long-distant dispersal in the genus, and species that do not show hybridogenic
orgin are confined to single islands or island grops, whilst taxa of hybrid origin are sometimes remarkably widespread.
