Protocols in ecological and environmental plant physiology


Australian Journal of Botany is an international journal for the publication of original research and reviews in plant science with relevance to Southern Hemisphere ecosystems including ecology and ecophysiology, conservation biology and biodiversity, forest biology and management, cell and molecular biology, palaeobotany, reproductive biology and genetics, mycology and pathology and structure and development.

Foliar physiognomic climate estimates for the Late Cretaceous (Cenomanian–Turonian) Lark Quarry fossil flora, central-western Queensland, Australia 
blank image
Tamara L. Fletcher, Patrick T. Moss and Steven W. Salisbury
pp. 575-582

The Cretaceous palaeoclimate on land is poorly understood when compared with sea-surface estimates. Using the relationship between the shape and size of woody dicot leaves and climate, we determined that, ~93 million years ago, Lark Quarry, central-western Queensland, was warm and wet. This insight allows us to further understand the environment in which angiosperms and associated insects diversified in, as well as the climatic conditions experienced by the area’s diverse vertebrate fauna.

Susceptibility to Teratosphaeria nubilosa and precocity of vegetative phase change in Eucalyptus globulus and E. maidenii (Myrtaceae)

Gustavo Balmelli, Sofía Simeto, Diego Torres, Alicia Castillo, Nora Altier and Julio J. Diez
pp. 583-591

We analysed the susceptibility of Eucalyptus globulus and E. maidenii to Teratosphaeria nubilosa. E. maidenii was less damaged than E. globulus but the change to adult foliage began significantly earlier on E. globulus. The work highlights the selection opportunities for sites at high risk of T. nubilosa infection.

Do leaf traits in two Dalbergia species present differential plasticity in relation to light according to their habitat of origin?

Ana Silvia Franco Pinheiro Moreira, Ana Clara Luppi Queiroz, Fernanda de Vasconcelos Barros, Maíra Figueiredo Goulart and José Pires de Lemos-Filho
pp. 592-599

Different growth environments can result in different leaf structure. In the present study, Dalbergia nigra (Atlantic forest species) and D. miscolobium (cerrado species) exhibited high phenotypic plasticity to light, although in different leaf traits. The forest species was more plastic when considering leaf traits that may be related to gas exchange (number of leaflets per leaf, stomatal pore area and density, percentage of leaflet occupied by stomatal pore area, and estimated stomatal conductance), whereas the cerrado species showed higher plasticity in light-interception traits, such as leaflet mass per area and leaflet thickness.

Managing nutrient regimes improves seedling root-growth potential of framework banksia-woodland species 
blank image
Erin Griffiths and Jason C. Stevens
pp. 600-610

Increasing seeding root growth potential is a critical factor in determining restoration success of banksia-woodland systems. Optimising nutrient regimes during nursery production provides an opportunity to increase root growth of Banksia and Eucalyptus species when outplanted into field conditions.

Embryonic development of Syagrus inajai (Spruce) Becc. (Arecaceae, Arecoideae), an Amazonian palm

Poliana Roversi Genovese-Marcomini, Maria Sílvia de Mendonça and Sandra Maria Carmello-Guerreiro
pp. 611-621

The study of the embryonic development of palms is essential for understanding the establishment and evolutionary success of these plants. The aim of this study was to carry out a morpho-anatomical analysis of the embryo of Syagrus inajai, in different phases of its development, culminating in the establishment of four specific development stages. These states are observed in other species of palms. The existence of an embryonic development pattern in this family is therefore proposed.

Effect of forest fragmentation and altitude on the mating system of Eucalyptus pauciflora (Myrtaceae)

Archana Gauli, René E. Vaillancourt, Dorothy A. Steane, Tanya G. Bailey and Brad M. Potts
pp. 622-632

Variation in mating system has important fitness and evolutionary consequences for plants. We examined the effects of forest fragmentation on the mating system of Eucalyptus pauciflora and showed that, while outcrossing rates were not affected, seed yield was reduced by fragmentation. This finding means that seed from remnant native trees of this species is unlikely to show deleterious effects of inbreeding and that locally collected seed is suitable for ecological restoration unless maladapted due to climate or other environmental change.

Impact of distance to mature forest on the recolonisation of bryophytes in a regenerating Tasmanian wet eucalypt forest 
blank image
Thomas P. Baker, Gregory J. Jordan, Patrick J. Dalton and Susan C. Baker
pp. 633-642

Understanding the ability of species to recolonise after disturbances created by forest harvesting is critical for sustainable forestry. This paper examined how bryophyte recolonisation was impacted by distance to a mature forest. Recolonisation of bryophytes declined with increasing distance to a mature forest and therefore the distance between retained mature forest patches should be considered in the management of forest harvesting.

Seed ecology of Lepidosperma scabrum (Cyperaceae), a dryland sedge from Western Australia with physiological seed dormancy 
blank image
S. R. Turner
pp. 643-653

Lepidosperma scabrum is a common understorey species currently required for urban bushland restoration, though its propagation has been highly problematic to date. In this study, the type of seed dormancy present in this species is defined along with the requirements to promote high levels of germination.

Recruitment of Eucalyptus strzeleckii (Myrtaceae) in remnant patches of native vegetation in the Latrobe Valley and South Gippsland, Victoria 
blank image
Harley Schinagl, Wendy Wright and Philip Rayment
pp. 654-662

Many remnant populations of the Environment Protection and Biodiversity Conservation Act 1999-listed Eucalyptus strzeleckii K.Rule (Strzelecki gum) are dominated by large, senescing trees and recruitment is rarely observed. The present study documented regeneration of saplings in good-quality habitats. The key variables influencing recruitment were identified and have implications for land managers.

Low-phosphorus conditions affect the nitrogen nutrition and associated carbon costs of two legume tree species from a Mediterranean-type ecosystem 
Anathi Magadlela, Aleysia Kleinert, Léanne L. Dreyer and Alex J. Valentine

Legumes from nutrient-poor ecosystems such as the Cape Floristic Region grow on variable P soils. We investigated legume adaptations to low P soils, and found that related legume species in nutrient-poor ecosystems can have very different strategies to ensure optimal mineral acquisition. Globally, the distribution of legumes in nutrient-poor soils may not rely on the same functional traits.

Spatial and temporal variation in damage and dieback in a threatened subantarctic cushion species 
J. Whinam, J. A. Abdul-Rahman, M. Visoiu, M.-B. F. di Folco and J. B. Kirkpatrick

Dieback in the cushion Azorella macquariensis, on Macquarie Island was monitored for four years. Although damage from wind appeared responsible for most damage at any one time, a yellow dieback, with symptoms consistent with a pathogen, caused the most rapid dieback.
