- Description: Riparian zones are a characteristic component of many landscapes throughout the world and increasingly are recognised as key areas for biodiversity conservation. Their importance for bird communities has been well recognised in semi-arid environments and in modified landscapes where there is a marked contrast between riparian and adjacent upslope vegetation. The value of riparian zones in largely intact landscapes with continuous vegetation cover is less well understood. In this study, birds were surveyed at 30 pairs of riparian and adjacent non-riparian sites in extensive mesic forests of the Victorian Highlands, Australia. Riparian sites were floristically distinct from non-riparian sites and had a more complex vegetation structure, including a mid-storey tree layer mostly absent from non-riparian sites. Bird assemblages at riparian sites had significantly greater richness, abundance and diversity of species than was recorded at adjacent non-riparian sites. Species composition also differed significantly between these habitat types. Compositional differences in assemblages were due to a suite of distinctive species in each habitat and to significant contrasts in the densities of species that occurred in both habitat types. Many species (36%) attained a significantly greater abundance in riparian habitats. The distinctiveness and richness of the riparian avifauna contribute to the diversity of continuous forest landscapes. The spatial patterning of the avifauna, the occurrence of complementary assemblages, the presence of rare species and the potential for riparian habitats to serve as refuges, all point to the value of riparian zones and highlight the importance of landscape-level planning and management for avifaunal conservation. © 2006 Elsevier Ltd.

- Description: Movement is a trait of fundamental importance in ecosystems subject to frequent disturbances, such as fire-prone ecosystems. Despite this, the role of movement in facilitating responses to fire has received little attention. Herein, we consider how animal movement interacts with fire history to shape species distributions. We consider how fire affects movement between habitat patches of differing fire histories that occur across a range of spatial and temporal scales, from daily foraging bouts to infrequent dispersal events, and annual migrations. We review animal movements in response to the immediate and abrupt impacts of fire, and the longer-term successional changes that fires set in train. We discuss how the novel threats of altered fire regimes, landscape fragmentation, and invasive species result in suboptimal movements that drive populations downwards. We then outline the types of data needed to study animal movements in relation to fire and novel threats, to hasten the integration of movement ecology and fire ecology. We conclude by outlining a research agenda for the integration of movement ecology and fire ecology by identifying key research questions that emerge from our synthesis of animal movements in fire-prone ecosystems.

- Description: Banksias are iconic Australian plants, with a Gondwanan origin. Their specialised roots help survival on low-phosphorus soils, and many species have reproductive cycles adapted to fire. They are trophically important in many of Australia’s native forests, woodlands and heathlands, providing nectar, pollen and seeds for many species of birds, mammals and invertebrates. While legacies of land use have reduced the historic extent of some Banksia species, more recent declines have raised additional concerns about their persistence in some landscapes. A range of factors are considered to be impacting Banksia persistence (Lamont et al. 2007), including habitat loss and fragmentation (e.g. Miller et al. 2020), increased fire frequency (e.g. Bradstock et al. 1997) and climate change (e.g. Steel et al. 2019), but there is no consensus about how these interacting factors may be driving declines, and how widespread these declines may be. The challenges facing Banksia species conservation in the south-eastern state of Victoria were the focus of an online workshop in May 2020. The workshop brought together researchers and land managers from Victorian and interstate universities, Victorian government agencies and volunteer land management groups to share their knowledge of the threats facing banksias, and document ideas to reverse declines. It was organised by Arthur Rylah Institute for Environmental Research (Department Environment, Land, Water and Planning), La Trobe University (Department of Ecology, Environment and Evolution) and Federation University (Centre for eResearch and Digital Innovation).
