S.Ayyub (Division of Ecology and Evolution, Research School of Biology, Australian National University); C. Linde (Division of Ecology and Evolution, Research School of Biology, Australian National University); B. Gooden (CSIRO, Health & Biosecurity).   Various factors may be associated with Eucalyptus dieback in Australia. To investigate Eucalyptus viminalis woodlands’ soil-mediated effects on plant performance, we conducted a greenhouse experiment […]

Heterodichogamy in Ascarina lucida (Chloranthaceae).

Phil Garnock-Jones (Victoria Uniiversity of Wellington). Ascarina lucida (Chloranthaceae) is an endemic New Zealand wind-pollinated small tree. Its sexual system has been described variously, as dioecious, gynodioecious, or monoecious with strong protandry. Inflorescences are terminal thyrses of 2–3-flowered cymules. Flowers are unisexual and highly reduced: each male flower is a single anther with about 80,000 small

Persoonia angustiflora? I hardly knew her! Reinstatement of a Western Australian taxon. 

Lindsay R. J. Shelton (Western Botanical Consultancy and The Western Australian Herbarium); Nicole Dakin (Western Botanical Consultancy) and Geoff Cockerton (Western Botanical Consultancy).  Preliminary data supports the reinstatement of an Eastern variety of Persoonia angustiflora endemic to the Parkers Range area in the Western Australian Goldfields. P. angustiflora var. burracoppinensis is morphologically readily separable from the Western form of P. angustiflora and should be

Phylogenetic diversity in conservation: why we should proceed with care.

Marcel Cardillo (Australian National University); Alex Skeels (Australian National University). Phylogenetic diversity (PD) connects systematics with conservation, by using phylogenetic branch lengths to quantify an assemblage’s “evolutionary history”, which is widely regarded as worthy of protection. Although PD is still rarely used in practical conservation decision making, it is becoming more visible in the international policy
