... by this study will be needed as many relevant sources of increase in variance, for example time and location, were avoided and this almost certainly reduced the standard deviation between trees. It is clear that further exploration of the measurement of species level biological diversity is urgently needed...

... Arid northwestern Australia contains one of the world’s more diverse subterranean faunas including many relict obligate groundwater (stygo-) faunas in karst and calcrete aquifers, principally crustaceans, with affinities pertinent to Tethys, and to Pangaea and its derived landmasses. Higher...

... when they should be considered exotic. Many native animals, including threatened species, are growing dependent upon exotic plants and animals, and this dependency calls into question the presumption that exotic means ‘bad’. Conversely, many native species behave at times as pests. The native-good...

... Urban bushland has survived for a variety of reasons. In some cases Sydney bushland is protected from possible development, but many stands do not enjoy protection under the planning process. Urban bushland is valued for a range of different purposes and if it is to survive then its permissible...

... The conservation status of sessile marine invertebrates is poorly understood. As a case study we present data for ascidians which share many of the problems that beset other invertebrates: i) they require a specialist to identify most of them; ii) our understanding of their biology...

... With their introduction into Australia beginning in the early nineteenth century deer have joined a long list of introduced species, many of which have become significant pests. Unlike rabbits, feral pigs, foxes and others, deer have not been considered to have had significant adverse...

... further reduced. Many of these threats, and indeed the greenhouse effect itself, are a consequence of too many people doing the wrong things in the wrong places. Unless there are serious attempts to address the population problem addressing other threats to biodiversity will be ultimately a futile...

... term, occasional high intensity wildfires in spring or summer encourage the growth of a dense understorey. Some fire regimes, particularly frequent, low-intensity bums in autumn currently used in forest management, will reduce and eventually eliminate the dense understorey. As it is lost, many native...

... No research funds have been made available to produce aversion agents and/or tactics to reduce the need for orchardists to cull flying-foxes to protect their crops. This has occurred despite many years of effort by growers to attract research funds from government and industry groups. It appears...

... Coastal biodiversity is complex due to the large numbers of species interacting in space and time at many different scales. Because little is known of the invertebrates which make up most of this biodiversity, conserving biodiversity is a difficult task. Robust analytical techniques must...

... The branchiopod family Chydoridae is present in many freshwater ecosystems, and chydorids are an important and significant component of aquatic food webs. These cladocerans are diverse and abundant, and provide an important link between primary producers and secondary consumers. They make good...

... The Greater Blue Mountains World Heritage Area (GBMWHA) is biologically diverse, including many unique and rare plants and animals as well as varied ecosystems. It also contains a large body of rock art - drawings, paintings, stencils, prints and engravings - in rock shelters and on rock...

... collecting sites. Many rare species were discovered only as a result of continuous or repeated trapping at a single site. Allowing for habitat differences, site richness is proportional to collecting intensity over time, and it is difficult to distinguish collecting history fro many inherent or special site...

... Museum collections are largely untapped sources of key information for the conservation of invertebrate biodiversity but in many cases these data are not readily available to land managers. Meanwhile significant faunal habitats containing much of Australia’s terrestrial invertebrate biodiversity...

... to these impacts due to specialised habitat requirements. Data collected over the past 15 years relating to vertebrate road mortality and trapping and tracking of small mammals, possums, herpetofauna and invertebrates confirm that many rainforest species suffer edge, linear barrier and disturbance impacts...
