Root traits are multidimensional: specific root length is independent from root tissue density and the plant economic spectrum
TLDR
Test the prediction that root, stem and leaf traits and relative growth rate respond in unison with soil fertility gradients and determine whether multiple root traits align with growth rate, leaf and stem traits and with each other. Expand
Methods for the extraction, storage, amplification and sequencing of DNA from environmental samples
TLDR
A standardised set of procedures for use on different taxa and sample media is proposed, largely based on recent trends in their use, and represents a framework for efficient, comprehensive and robust DNA-based investigations of biodiversity, applicable to mostTaxa and ecosystems. Expand
Revised circumscription of Nothofagus and recognition of the segregate genera Fuscospora , Lophozonia , and Trisyngyne (Nothofagaceae)
TLDR
A new phylogenetic analysis of morphological characters is presented and it is argued that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Noth ofagus with four subgenera.

Phylogeny and biogeography of Craspedia (Asteraceae: Gnaphalieae) based on ITS, ETS and psbA-trnH sequence data
TLDR
The single lineage of New Zealand Craspedia and the low divergences between Australian and New ZealandCraspedia samples are consistent with the derivation of New Zealander's species via a single dispersal event from south-east Australia in the Late Tertiary or Quaternary. Expand
Subfamilial relationships within Caryophyllaceae as inferred from 5' ndhF sequences.
TLDR
It is concluded that morphological characters previously used to delimit subfamilial groupings in the Caryophyllaceae are apparently unreliable estimators of phylogeny. Expand
Phylogenetic implications of trans-specific chloroplast DNA sequence polymorphism in New Zealand Gnaphalieae (Asteraceae)
TLDR
The New Zealand endemic species of Gnaphalieae (Asteraceae) present a bewildering array of morphological forms recalcitrant to phylogenetic analysis using molecular or traditional characters, which suggest a complex set of interrelationships among extant species and genera as currently circumscribed. Expand
Two genetic and ecological groups of Nostoc commune in Victoria Land, Antarctica, revealed by AFLP analysis
TLDR
The results suggest that environmental factors linked to latitude are not the greatest drivers of genetic variation in Victoria Land and advocate extensive sampling across local environmental gradients based on water availability, comparative culturing, and development of sequence characterised amplified regions (SCARs) across a range of latitudes in future seasons of the Latitudinal Gradient Project. Expand
Morphological and genetic evidence of contemporary intersectional hybridisation in Mediterranean Helichrysum (Asteraceae, Gnaphalieae).
TLDR
Fertility of hybrids is demonstrated by the viability of seeds produced by hybrids from both localities, and the detection of a backcross specimen to H. orientale and H. stoechas. Expand
Genetic variation in Mediterranean Helichrysum italicum (Asteraceae; Gnaphalieae): do disjunct populations of subsp. microphyllum have a common origin?
TLDR
Analysis of AFLP, cpDNA sequences and morphological characters show that there is geographic structure to the genetic variation within H. italicum, with eastern and western Mediterranean groups, which do not correspond with the division into subsp. Expand
