Aim  We characterized changes in reporting rates and abundances of bird species over a period of severe rainfall deficiency and increasing average temperatures. We also measured flowering in eucalypts, which support large numbers of nectarivores characteristic of the region. 
Resistance and resilience: can the abrupt end of extreme drought reverse avifaunal collapse?
How the avifauna of a highly modified region responded to a 13year drought followed by a two-year period of substantially higher than average rainfall suggests a widespread mechanism is responsible for declines.
BIODIVERSITY RESEARCH: Diversity and distribution of macroinvertebrates in lentic habitats in massively altered landscapes in south‐eastern Australia
Aim  We investigated whether faunas of lentic macroinvertebrates differed among two landscape types: (1) those that are largely covered in forests (presumed to be in a more pre‐human‐impact
The interaction between land use and catchment physiognomy: understanding avifaunal patterns of the Murray–Darling Basin, Australia
Aim  We assessed whether different patterns of land use within similar physiognomic catchments (= watersheds) produced discernible effects on avian assemblages and, if so, whether such effects were
Fire, drought and flooding rains: The effect of climatic extremes on bird species’ responses to time since fire
Climatic extremes and fire affect ecosystems across the globe, yet our understanding of how species are influenced by the interaction of these broadscale ecological drivers is poorly understood.
Avifaunal disarray: quantifying models of the occurrence and ecological effects of a despotic bird species
Noisy miner densities increased with proximity to forest edges (higher densities on forest edges and open sites), in low rainfall areas, and in vegetation dominated by trees with blade-shaped rather than needle-shaped leaves.
Avifaunal disarray due to a single despotic species
The evidence for widespread assemblage-level phase shifts across eastern Australia is reviewed, triggered partly by anthropogenic habitat alteration and mediated by a native, despotic bird: the noisy miner Manorina melanocephala.
The past, present and potential future distributions of coldadapted bird species
Aim Species’ distributions change through time, and many species have recently shifted their ranges in response to anthropogenic climate change. However, predicting future distributional changes
Interrogating recent range changes in South African birds: confounding signals from land use and climate change present a challenge for attribution
Aim  Apparent anthropogenic warming has been underway in South Africa for several decades, a period over which significant range shifts have been observed in some indigenous bird species. We asked
No short-term change in avian assemblage following removal of Yellow-throated Miner (Manorina flavigula) colonies
This study was undertaken in part thanks to funding by Biosis Research, Pty Ltd, and staff at the Walpeup Research Station, ParksVictoria and the Ouyen Caravan Park.


Tree Hollows and Wildlife Conservation in Australia
This work is an account of the dependent fauna of Australia, and introduces a considerable amount of new data on development of hollows, selection by fauna, pests and introduced species, and artificial hollows.
Use of guilds for modelling avian responses to vegetation in the Intermountain West (USA)
Aim  Individually focused conservation management of many species is expensive and logistically impractical. Mesofilter conservation methods may facilitate the simultaneous management of multiple
Seasonal Movements in the Australian Honeyeaters (Meliphagidae) and Their Ecological Significance
The Meliphagidae (honeyealers), the largest Australian bird family (69 species), have diverse and complicated patterns of seasonal movements, which are defined and their evolutionary, ecological and behavioural patterns are defined.
Influences of species, latitudes and methodologies on estimates of phenological response to global warming
New analyses are presented addressing the global impacts of recent climate change on phenology of plant and animal species. A meta‐analysis spanning 203 species was conducted on published datasets
Seasonal variation and the effects of drought on the abundance of arthropods in savanna woodland on the Northern Tablelands of New South Wales
Most arthropod groups were greatly reduced in number during the drought and some groups virtually disappeared, although coleopterans were not significantly affected.
Native bird breeding in a chronosequence of revegetated sites
It is shown that there is very little breeding activity in replantings by species that have declined dramatically in rank abundance between large ‘reference’ areas and fragmented landscapes, suggesting that in-site habitat structure is the predominant driver.
The lag daemon: hysteresis in rebuilding landscapes and implications for biodiversity futures.

Landscapes must be conceived, and managed, as spatial and temporal mosaics to allow for persistence of the full set of species that should occupy them, meaning that senescing and replanted habitats may need to be juxtaposed.
Are Replanted Floodplain Forests in Southeastern Australia Providing Bird Biodiversity Benefits?
Revegetation of massively altered landscapes for multiple benefits (including biodiversity and ecological function) has accelerated over the past two decades in southern Australia. However, much of
Geographical expansion and increased prevalence of common species in avian assemblages: implications for large‐scale patterns of species richness
Modern processes have played a role in shaping the distribution patterns of species richness at large spatial scales based on the composition of common and rare species, and this suggests that anthropogenic activities cannot be ignored as a possible causal factor when considering ecological patterns atLarge spatial scales.
Refugees and residents: densities and habitat preferences of lorikeets in urban Melbourne
The high densities of Musk Lorikeets recorded possibly reflect a paucity of flowering in Victorian BoxIronbark forests during the autumnlwinter of 2002 and the availability of supplementary nectar resources in the urban environment.
