Abstract Aim After environmental disasters, species with large population losses may need urgent protection to prevent extinction and support recovery. Following the 2019–2020 Australian megafires, we estimated recovery in fire‐affected fauna, inform conservation status assessments management. Location Temperate subtropical Australia. Time period 2019–2030 beyond. Major taxa terrestrial freshwater vertebrates; one invertebrate group. Methods From > 1,050 taxa, selected 173 whose...
Summary 1. Expert knowledge is used routinely to inform listing decisions under the IUCN Red List criteria. Differences in opinion arise between experts presence of epistemic uncertainty, as a result different interpretations incomplete information and differences individual beliefs, values experiences. Structured expert elicitation aims anticipate account for such increase accuracy final estimates. 2. A diverse panel 16 independently evaluated up 125 parameters per taxon assess category...
ABSTRACT In the development of a species distribution model based on regression techniques such as generalized linear or additive modelling (GLM/GAM), basic assumption is that records presence and absence are real. However, common concern in many studies examining distributions absences cannot be inferred with certainty. This particularly case where rare, difficult to detect and/or does not occupy all available habitat considered suitable. The western ground parrot ( Pezoporus wallicus...
Aim: Increasing interest in holistic measurement of the response fauna communities to interventions requires suitable community condition metrics. However, development such metrics is hindered by absence broad-scale typologies at spatial and ecological resolutions. We aimed derive a preliminary typology terrestrial bird for Australia, based on co-occurrence data, describe map likely distribution each type across continent. Location: Mainland continental islands Time period: 1973-2022 Major...
Abstract Flowering phenology and seed set characteristics of five species Banksia were studied in relation to the nectarivorous birds which feed at their inflorescences. Within woodland study site near Perth, flowering seasons sequential only slightly overlapping, providing a year‐round nectar source. Although honeyeaters visited alt species, was very low each case. Caging experiments indicated that, B. attenuata least, alternative pollinators may play more important role pollination than do...
Catastrophic megafires can increase extinction risks; identifying species priorities for management and policy support is critical preparing responding to future fires. However, empirical data on population loss recovery post-fire, especially megafire, are limited taxonomically biased. These gaps could be bridged if species' morphological, behavioural, ecological life history traits indicated their fire responses. Using expert elicitation that estimated changes following the 2019–20...
Abstract The influence of animals on patterns seed dispersal has not been well explored, despite the importance in plant population biology. Furthermore, exploitation as agents considered one reason for replacement gymnosperms by angiosperms Cretaceous. We studied a cycad , Macrozamia riedlei, and showed that absence animals, ripe seeds drop directly beneath parent more than 40 cm from base. Several eat fleshy outer integument seeds, possums (Trichosurus vulpecula), transport up to 24 m...
Reduction in seed set after self-pollination compared to that cross-pollination is widespread Stylidium. No evidence was found for the existence of any kind prezygotic incompatibility. Evidence presented support suggestion recessive lethal equivalents act discriminate against products self-pollination. These factors induce ovule or abortion entry pollen tube into micropyle ovule, and they are abundant natural populations most perennial Stylidium species. Patterns suggest an average plant may...
Abstract ContextFeral cat predation has had a significant impact on native Australian fauna in the past 200 years. In early 2000s, population monitoring of western ground parrot showed dramatic decline from pre-2000 range, with one three meta-populations declining to very low levels and second becoming locally extinct. We review 8 years integrated introduced predator control, which trialled incorporation feral bait Eradicat® into existing fox baiting programs. AimsTo test efficacy...
Summary In conservation management, ensuring that the most appropriate research is conducted and results are actually put into practice a complex challenging process. While there success stories, many hurdles can reduce likelihood of being initiated its findings communicated implemented. This article describes ideal research–management cycle, summarizes major factors impede it draws on experiences authors to provide series examples successful approaches help keep cycle going. We consider...
The Pilbara region has one of the most diverse reptile assemblages in world and includes many typical arid zone species as well saxicoline endemics. We present results a four-year survey during which pitfall trap lines were used to sample 297 quadrats for total two weeks spring autumn. located across chosen main substrate types. Environmental variables measured characterise soil geomorphic, vegetative climatic setting each quadrat. program PATN expose patterns composition among quadrats,...
Abstract In an era characterized by recurrent large wildfires in many parts of the globe, there is a critical need to understand how animal species respond fires, rates at which populations can recover, and functional changes fires may cause. Using quantified habitat parameters over ~400‐yr post‐fire chronosequence obligate‐seeding Australian eucalypt woodland, we build test predictions birds, as individual aggregated into groups according their use specific resources, time since fire....
The geographic range, status and breeding season are documented for 325 bird species known to occur in the Pilbara, Western Australia, since first records were made 1699.The fauna is a mixture of Torresian, Eyrean Bassian components, along with variety seabirds, migratory wading birds Asian vagrants.The region lies entirely within arid zone overall harshness environment means that few resident.The richness total avifauna (resident non-resident) due mainly diversity habitats, especially those...
Automated recording units (ARUs) are an integral instrument in a broad range of applications such as invasive species management, behavioural studies, and environmental impact assessments. They have become particularly important conservation programmes for cryptic threatened bird species. While the fundamental issues signal attenuation degradation well known, understanding how factors influence detectability calls on ARU recordings particular circumstances is essential accurate...
As part of a regional biodiversity survey, in total 304 quadrats, 1 ha each, were positioned to represent the diversity physical environments across geographical extent Western Australian wheatbelt. Uncleared sites variously affected/unaffected by salinity chosen, but those showing overt changes caused other types disturbance avoided as far possible.Drift fences and pit traps used compile lists ground-dwelling spiders, scorpions, frogs, reptiles mammals on quadrats. For analysis, these data...
A population of Night Parrots (Pezoporus occidentalis) was discovered in 2013 western Queensland and has become the primary focus efforts aimed at conserving habitat protecting species from extinction. Critical information on nesting location, breeding season behaviour, clutch size success is currently limited to anecdotal 19th-century observations accounts by early natural historians. Here we describe several attempts Pullen Reserve. Our include nest fledgling descriptions, characteristics,...
Abstract Conservation translocation is a valuable management tool for conserving and restoring biodiversity. managers researchers strive success spend considerable time energy planning positive outcome. However, many translocations fail. Defining what makes ‘successful’ can be challenging. Criteria must relevant to the objectives of translocation, should measurable have realistic timeframes achievement. How we evaluate these criteria highly dependent on our ability monitor species...
Abstract Conservation translocations have become an increasingly popular method to restore or secure vulnerable populations. However, greatly vary in success. The use of population viability analysis (PVA) may increase the likelihood meeting translocation goals. quality PVAs inform is dependent on availability ecological data and clear objectives guide them. Here, we used planned conservation Western Grasswren (Amytornis textilis textilis) from mainland Shark Bay onto Dirk Hartog Island,...
AbstractMeasures of abundance and population trends are necessary for informed management rare species, but obtaining reliable estimates sparsely occurring species is an ongoing challenge in conservation biology. It even more difficult when the interest also cryptic. We censused a one such Western Ground Parrot (Pezoporus wallicus flaviventris), over several years to develop monitoring protocol assist future management, extend understanding its response fire, provide model that could be used...
We report on a specimen of the Night Parrot (Pezoporus occidentalis) found dead in Diamantina National Park, western Queensland. It was low dissected tableland near head small creek, an area vegetated by sparse shrubland Gidgee (Acacia cambagei), Crimson Turkey Bush (Eremophila latrobei) and Blunt-leaf Cassia (Senna artemisioides var. helmsii.) Conditions were dry vegetation not flowering or seeding. is second such to be region since 1990. The two specimens less than 200 km apart. Molecular...
