Forest carbon in lowland Papua New Guinea: Local variation and the importance of small trees.

Austral Ecol 2015 Apr 25;40(2):151-159. Epub 2014 Sep 25.

Bell Museum and Department of Plant Biology, University of Minnesota Saint Paul, Minnesota, USA.

Efforts to incentivize the reduction of carbon emissions from deforestation and forest degradation require accurate carbon accounting. The extensive tropical forest of Papua New Guinea (PNG) is a target for such efforts and yet local carbon estimates are few. Previous estimates, based on models of neotropical vegetation applied to PNG forest plots, did not consider such factors as the unique species composition of New Guinea vegetation, local variation in forest biomass, or the contribution of small trees.

Ecology and bioprospecting.

Austral Ecol 2011 May 19;36(3):341-356. Epub 2010 Aug 19.

Department of Biological Sciences, Macquarie University, North Ryde, NSW 2109.

Bioprospecting is the exploration of biodiversity for new resources of social and commercial value. It is carried out by a wide range of established industries such as pharmaceuticals, manufacturing and agriculture as well as a wide range of comparatively new ones such as aquaculture, bioremediation, biomining, biomimetic engineering and nanotechnology. The benefits of bioprospecting have emerged from such a wide range of organisms and environments worldwide that it is not possible to predict what species or habitats will be critical to society, or industry, in the future.

The loss of aquatic and riparian plant communities: Implications for their consumers in a riverine food web.

Austral Ecol 2008 Aug 4;33(5):672-683. Epub 2008 Jul 4.

School of Earth and Environmental Science, University of Adelaide, Adelaide, SA 5005, Australia (Email:

Human induced alterations to rivers and steams have resulted in significant changes to the structure and diversity of riparian and aquatic plant communities. These changes will impact on the dynamics of riverine carbon cycles and food web structure and function. Here we investigate the principal sources of organic carbon supporting local shredder communities across a gradient in different levels of anthropogenic development along riverine reaches, in South Australia.

Habitat structure is more important than vegetation composition for local-level management of native terrestrial reptile and small mammal species living in urban remnants: A case study from Brisbane, Australia.

Austral Ecol 2007 Sep 6;32(6):669-685. Epub 2007 Aug 6.

Centre for Innovative Conservation Strategies and Australian School of Environmental Studies, Griffith University, Nathan, Queensland, Australia.

As urban areas continue to expand and replace natural and agricultural landscapes, the ability to manage and conserve native wildlife within urban environments is becoming increasingly important. To do so we first need to understand species' responses to local-level habitat attributes in order to inform the decision-making process and on-ground conservation actions. Patterns in the occurrence of native terrestrial reptile and small mammal species in 59 sites located in remnant urban habitat fragments of Brisbane City were assessed against local-level environmental characteristics of each site.

Structure and environmental relationships of insectivorous bat assemblages in tropical Australian savannas.

Austral Ecol 2005 Dec 23;30(8):906-919. Epub 2005 Nov 23.

Biodiversity Conservation, Department of Natural Resources, Environment and the Arts, Alice Springs, Northern Territory, Australia.

Patterns in the composition of assemblages of microbat species sampled during the late dry season (the 'build-up') in north Australian savannas were assessed against a range of environmental factors as well as four defined habitat types (riparian, escarpments, coastal and woodlands). Distinct species assemblages were most strongly associated with topographic and climatic variables. There were also limited associations with vegetation structure, fire and local roost potential but no associations with insects or water availability. Read More

Net woody vegetation increase confined to seasonally inundated lowlands in an Australian tropical savanna, Victoria River District, Northern Territory.

Austral Ecol 2004 Dec 12;29(6):667-683. Epub 2009 Oct 12.

Key Centre for Tropical Wildlife Management, Northern Territory University, Darwin NT, Australia.

Georeferenced digital aerial photographs were used to assess changes in overstorey vegetation cover since 1948 in the Victoria River District, Northern Territory, Australia, across a range of lowland tropical savanna habitats and with explicit consideration of known and variable site-specific grazing and fire management histories. Vegetation surveys at corresponding locations on the ground identified five distinct woody vegetation communities defined primarily by water drainage and secondarily by soil characteristics. Air-photo analyses revealed that, contrary to popular perceptions and in contrast to results from other habitats, there has been no generalized net increase in overstorey woody vegetation cover across the full range of lowland savanna habitats.

Dormancy and germination characteristics of herbaceous species in the seasonally dry tropics of northern Australia.

Austral Ecol 2000 Jun 24;25(3):213-222. Epub 2001 Dec 24.

CSIRO Tropical Agriculture, 306 Carmody Road, St Lucia, Queensland 4067, Australia (Email: and CSIRO Wildlife and Ecology, Canberra, ACT, Australia.

This study investigated changes in dormancy and germination over 8 months for 23 common species (annual and perennial grasses, legumes and other dicotyledons) from herbaceous communities in northern Australia. Seeds were exposed to three storage treatments: relatively constant laboratory conditions, an oven with fluctuating temperatures similar to those found on the soil surface (25/60°C), or exposed on the soil surface at Townsville. There were wide ranges of initial levels of dormancy (9-100%), rates of change of dormancy and response to the different storage conditions showing that species with several types of dormancy characteristics are able to coexist in these communities.
