Contraction–Expansion Dynamics Shape Refugia and Recolonisation Processes in the Gondwana Rainforests of Australia World Heritage Area
Climate stability and historical gene flow have shaped distinct refugial and recolonised areas within the Gondwana Rainforests of Australia World Heritage Area (GRWHA), with significant implications for future conservation. The study identified persistent refugia—regions of high climate stability, species richness, and genetic differentiation—and recolonised zones marked by lower stability but higher genetic diversity. Notably, the Clarence River Corridor acts as both a biogeographic barrier and a zone of admixture, homogenizing genetic signals. While rainforest suitability expanded post-Last Glacial Maximum (LGM), future projections indicate substantial contraction, particularly in southern regions, with high-altitude refugia emerging. This multi-species approach integrates climate modeling, landscape genomics, and intraspecific diversity metrics to inform regionally tailored restoration strategies, prioritizing provenancing guidance and assisted migration under climate change.
Environmental Controls of Rainforest Tree Communities: Climate Change Implications for the Gondwana Rainforests
A 15-year study of the Gondwana Rainforests of Australia reveals significant floristic changes driven by elevation-dependent environmental controls. High-elevation tree communities (≥ 900 m) show persistent in situ recruitment patterns, closely mirroring canopy composition, and are primarily influenced by precipitation and cloud water inputs, which mitigate moisture stress. In contrast, mid-to-low elevations (≤ 700 m) exhibit distinct understorey recruit compositions differing from the established canopy, linked to higher temperatures, evaporation, and lower humidity. These changes, particularly pronounced at low elevations (300 m), are exacerbated by drought and bushfires, suggesting a trajectory toward future community turnover. Climate projections indicate increasing moisture stress and fire risk, potentially threatening the Outstanding Universal Value of this UNESCO World Heritage Area. The study used multivariate analyses to examine shifts in tree community composition and their environmental drivers, providing critical insights for management strategies.
Long-term demographic responses to historical logging and ongoing climate change in an upland subtropical rainforest
Historical logging and ongoing climate change continue to significantly impact the recovery of upland subtropical rainforests in southeast Queensland, part of Australia's Gondwana Rainforests World Heritage Site. Despite over 50 years since logging cessation, these forests show persistent structural and compositional differences compared to intact plots, with logged areas exhibiting higher recruitment of pioneer species but greater sensitivity to warming temperatures and extreme weather events. The study, utilizing a rare long-term dataset spanning 1962–2015, found that while logged plots demonstrate faster diameter growth initially, this slows as basal area increases. Intact plots, conversely, show growth concentrated in larger, cloud-water-intercepting trees. These findings highlight the enduring legacy of logging and the need for adaptive management strategies to mitigate climate change impacts on these critical biodiversity refugia.

Population genomics of rainforest mountain frogs (Anura: Limnodynastidae: Philoria) severely impacted by the Australian megafires
The Australian megafires of 2019/20 severely impacted six of seven montane frog species in the genus Philoria, which are endemic to the Gondwana Rainforests of Australia. Population genomics analysis revealed that narrow-range species can be managed as single populations, while P. kundagungan, P. loveridgei, and P. sphagnicolus exhibit strong genetic differentiation between mountaintop populations, indicating limited natural dispersal. Fire-impacted populations, such as P. pughi and P. knowlesi, may face long-term threats due to reduced adaptive capacity. The study recommends prioritizing in situ conservation, genetic rescue, and translocation efforts to enhance resilience in these isolated, ancient frogs, emphasizing the need for updated fire buffer management in a changing climate.
Another ghost of Gondwana—Progradungula barringtonensis Michalik & Smith, sp. nov., a new species of the relict spider genus Progradungula (Araneae: Gradungulidae) from a temperate rainforest in eastern Australia
Researchers have discovered a new species of relict spider, Progradungula barringtonensis, from the temperate rainforests of Barrington Tops National Park in eastern Australia. This finding expands the known diversity of the genus Progradungula, which includes only two other species, both considered 'living fossils.' The newly described species exhibits unique characteristics in its male genitalia and web structure, showing plasticity that may be influenced by food availability. The study combines morphological analysis with field observations to shed light on the evolutionary history and ecological adaptations of these rare spiders, contributing to our understanding of Gondwana's ancient biodiversity.
New species and records of earthworms (Oligochaeta: Megascolecidae) from Queensland’s Scenic Rim
Researchers have identified new species of earthworms (Oligochaeta: Megascolecidae) within Queensland’s Scenic Rim, a critical part of the UNESCO-listed Gondwana Rainforests of Australia. This discovery underscores the region's rich biodiversity, particularly among invertebrates, which are often overlooked despite their ecological significance. The study highlights the likely presence of additional undocumented species due to earthworms' limited mobility and the fragmented nature of the Scenic Rim, suggesting further exploration is warranted. The research contributes to our understanding of the complex ecosystems within this World Heritage Area.
Paleobotany reframes the fiery debate on Australia's rainforest edges
Fossil evidence from Argentina and eastern Australia reveals that biodiverse rainforests with abundant Eucalyptus existed over 50 million years ago, shaped by nonfire disturbances like landslides and volcanic flows. The dominance of fire-adapted eucalypts is linked to more recent geological and climatic changes, including C4 grassland expansion and human activity. This challenges the narrative that tall eucalypt forests (TEFs) are threatened by 'invasive' neighboring rainforests, suggesting instead that both ecosystems are part of a single humid forest system with ancient, evolving interactions. The study urges a reevaluation of management practices to protect the outstanding World Heritage values and carbon storage of these areas, emphasizing the need for restoration and research focused on rainforest margins.
Investigating the role of the World Heritage brand in attracting visitors to protected areas in Queensland, Australia
Approximately one in four visitors to UNESCO World Heritage Sites in Queensland, Australia, indicated that the World Heritage brand influenced their decision to visit. This study is the first in-depth exploration of visitor awareness and preference for the World Heritage brand, revealing that while brand recognition varies significantly across sites—with only one-third of visitors recalling it spontaneously—it remains a powerful motivator for tourism. The research developed a practical framework for understanding protected area brands' roles among stakeholders and established baseline sociodemographic data across Queensland’s World Heritage Sites. Methodologically, the study employed focus groups, visitor surveys (1,827 valid responses), expert interviews, and on-site observations, analyzing data through descriptive statistics and chi-square tests to assess brand influence. Findings have already informed national and international policy on World Heritage branding.
What type of rainforest burnt in the South East Queensland's 2019/20 bushfires and how might this impact biodiversity
During Australia's 2019/20 bushfires, 12% of South East Queensland's (SEQ) rainforest estate, including parts of the UNESCO World Heritage Gondwana Rainforests, was affected by fires. Surprisingly, the wettest rainforest types and putative past refugia experienced higher burn rates than expected, challenging traditional assumptions about fire resilience in such ecosystems. The study used NIAFED data combined with regional ecosystem mapping to estimate burn areas and severity, revealing that while most fires were low-severity, patches of high severity occurred. Biodiversity impacts were assessed using previous estimates for each rainforest type, highlighting the potential threat to endangered rainforest species like semi-evergreen vine thickets on igneous rocks, where 50% of remnants may have burned. The findings suggest that under drought conditions, any rainforest is vulnerable, implying a contraction of rainforest areas if climate change exacerbates wildfires and droughts.
A new species of Philoria (Anura: Limnodynastidae) from the uplands of the Gondwana Rainforests World Heritage Area of eastern Australia
Researchers have identified a new species of mountain frog, Philoria knowlesi, within the Gondwana Rainforests World Heritage Area of eastern Australia. This discovery was made through comprehensive genetic sampling and analysis, including SNP data from the nuclear genome, which revealed distinct genetic lineages in the central and western McPherson Ranges. The study also clarified the distributions of two other species, P. loveridgei and P. kundagungan, while highlighting significant threats to these amphibians, including climate change and chytridiomycosis. All three taxa—Philoria knowlesi, P. loveridgei, and P. kundagungan (including its northern subpopulation)—are classified as Endangered (EN), with the southern subpopulation of P. kundagungan critically endangered (CR). The findings underscore the urgent need for conservation efforts to protect these highly threatened species.
Beyond bushfire severity: mapping the ecological impact of bushfires on the Gondwana Rainforests of Australia World Heritage Area
Bushfire severity mapping in Queensland's Gondwana Rainforests World Heritage Area properties following the 2019/20 wildfires was found to under-predict ecological impact, particularly in closed-canopy rainforests. This oversight biased against prioritizing rainforest-dependent threatened fauna for assessment and recovery resource allocation. The study introduces an approach that incorporates fire tolerance of vegetation communities to extend bushfire severity mapping, predicting potential ecological impact on ecosystems and priority species. By prioritizing threatened species based on ecological impact rather than fire severity alone, post-fire surveys and monitoring can be more effectively targeted, directing resources and recovery actions towards areas of greatest concern.
Extensive range contraction predicted under climate warming for two endangered mountaintop frogs from the rainforests of subtropical Australia
Two endangered mountaintop frogs, Philoria kundagungan and Philoria richmondensis, endemic to the Gondwana Rainforests of Australia World Heritage Area (GRAWHA), face severe range contraction due to climate warming. Under projected low and high warming scenarios by 2055, their habitats are expected to shrink by 64% to 91% for P. kundagungan and 50% to 85% for P. richmondensis, respectively. The study used the maximum entropy approach to model current and future distributions, validated against field data, revealing alarming declines that necessitate urgent conservation action. Proposed strategies include establishing ex-situ insurance populations and conservation translocations to ensure long-term survival amid ongoing threats such as wildfires.
Propositional A/r/tography: An Analytical Protocol
Propositional A/r/tography introduces a novel analytical protocol that leverages speculative and propositional potentials to deepen understanding of a/r/tographic renderings. This approach serves as an experimental gateway for generating layered, iterative data, offering new methods for analysis in qualitative research. Developed through fieldwork with young people in the UNESCO-listed Gondwana Rainforests of Australia, the protocol responds dynamically to processes of making, materiality, and mapping, providing a framework for speculative propositions that encourage further exploration and experimentation with visual renderings.
Conserving Refugia: What Are We Protecting and Why?
Refugia serve as vital conservation tools by buffering environmental conditions and safeguarding species and communities. This study introduces three novel definitions for refugia—persistent, future, and temporary—that integrate ecological and evolutionary dynamics into a decision-making framework applicable across varying temporal and spatial settings. These definitions are supported by criteria for identification, core value, and management strategies to guide both short- and long-term conservation efforts. Using the World Heritage Gondwana Rainforests (WHGR) of eastern Australia as a case study, the research illustrates how recognizing buffer zones, corridor connections, and emergency species translocations can protect critical assets following extreme events like the 2019–2020 fires. The findings emphasize the importance of safeguarding ecological and evolutionary processes across scales to enhance biodiversity conservation outcomes.
Disparate origins for endemic bird taxa from the ‘Gondwana Rainforests’ of Central Eastern Australia
A phylogenetic analysis of eight bird taxa endemic to Central Eastern Australia's Gondwana Rainforests reveals disparate origins, with five showing Plio-Pleistocene divergences from northern relatives, indicating recent lowland rainforest expansion and contraction. In contrast, two upland species, the rufous scrub-bird and logrunner, diverged during the Miocene, suggesting longer persistence and temperate origins. Additionally, reciprocal monophyly was not recovered in mitogenomes of Albert’s lyrebird and superb lyrebird. These findings support the rainforests' biota comprising isolates of varying ages and origins.

Researchers have identified two new species of crayfish, Euastacus binzayedi and Euastacus angustus, within the Gondwana Rainforests of Australia. These species, distinguished by unique morphological traits such as dorsal and ventral chelae protrusions in E. binzayedi and a laterally compressed body with prominent ventromesial carpal spine in E. angustus, exhibit significant genetic divergence from closely related species, with estimates of 4.8% and 8.7%, respectively. Both species are exceptionally rare, known only from single localities. The study highlights the biodiversity richness of the Gondwana Rainforests while emphasizing the need for conservation efforts to protect these newly discovered taxa.
The scenic rim of southeastern Queensland, Australia: A history of mid Cenozoic intraplate volcanism
A study of the Scenic Rim in southeastern Queensland, Australia, reveals a detailed history of mid Cenozoic intraplate volcanism linked to significant changes in the Australian plate's velocity. The research indicates that a major slowdown in plate movement began around 26 million years ago and lasted until 23 million years ago, coinciding with the collision of the Ontong Java plateau with the northern subduction margin of the Australian plate. Trace element and isotopic analyses show minimal contamination for most volcanic units, except rhyolites formed during the slow plate velocity period. The study also highlights the presence of highly evolved rocks, such as comendites, with extreme concentrations of incompatible elements, and provides insights into the melting and mixing processes in the upper mantle and lower crust. The region's diverse landscapes and wildlife habitats, including parts of the World Heritage listed Gondwana Rainforests, offer excellent exposures of subsurface magmatic architecture.
