However, along its peripheral agricultural frontiers, mammal assemblages are gradually being eroded due to deforestation of this large area known as the Arc of Deforestation, particularly along the Amazon's southeast. In this study, we aimed to expand on the knowledge of richness, composition, and defaunation of mammal assemblages in two priority protected areas for biodiversity in the region: Cristalino State Park (hereafter Cristalino) and Xingu State Park (hereafter Xingu). We used camera traps and line transects for data collection between 2020 and 2021. Our results demonstrated that both protected areas support rich assemblages of medium- and large-sized mammals within the south-central Amazon (Cristalino—32 species, Xingu—30 species). Due to the differing vegetation types between each park, the two mammal assemblages showed significant differences in species composition. Even with one of the highest biomasses of large ungulates (tapir and brocket deer) and apex predators (jaguar and puma) compared to other protected areas in south-central Amazon, both areas showed a high biomass defaunation index relative to these same areas. The result is largely driven by the low abundance of peccaries, especially <i>Tayassu pecari</i>. This could be one of the impacts of extensive human pressure caused by deforestation and degradation around and inside these protected areas. Both parks play an important role in the survival of threatened mammals, and in maintaining biodiversity and ecosystem functionality in the southern Amazon, helping to curb agricultural expansion into the interior of the Amazon rainforest.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70088","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using PlantSearch data from outside species-native distributions, it was found that species potential niches displayed a ‘centrifugal organisation’ of thermal niches. As a result, ‘potential niches of cold-adapted species extend to warmer temperatures, whereas potential niches of warm-adapted species extend to cooler temperatures’. These patterns could have important implications for tree species management under climate change, and the study described here aimed to determine if similar patterns could be found with the MAT niches of eucalypt species. The realised niches of 48 eucalypt species and subspecies were assessed in terms of MAT range using maps from a 2016 book and 2022 paper as well as the Atlas of Living Australia (ALA). Potential niches for 44 species and subspecies were examined using ex situ data from the PlantSearch database of Botanic Gardens Conservation International (BGCI). Results from the study described here were less clear-cut than the North American study, but some similarities were found. For example, potential niches of cold-adapted species extended to warmer temperatures, whereas potential niches of warm-adapted species extended to cooler temperatures. In summary, there was some support for the conclusions of the North American study. However, data from arboreta and botanic gardens should be used with care or levels of species climatic tolerance may be exaggerated. The collation of data from commercial trials, which would be more representative of broadscale areas and could also include provenance as well as species information, is recommended.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strength of fish-habitat associations can be indicative of ecosystem resilience, making them important benchmarks for ecological monitoring. These relationships are relatively unknown in mesophotic (30–150 m) marine systems due to the constraints of sampling in deeper waters. We aimed to assess fish-habitat associations in two unstudied no-take National Park Zones in the recently established Abrolhos Marine Park, Western Australia. We used the first baited remote underwater stereo-video systems (stereo-BRUVs) in this area to quantify demersal fish and benthic habitats between 33 and 154 m depth and modelled associations among fish species, traits and environmental covariates using Hierarchical Modelling of Species Communities (HMSC). Significant evidence of species-environment, trait-environment, and species-species associations was identified which may influence local community assembly. Benthic habitats explained 62.4% of the modelled variation in fish abundance, and 7 of the 21 modelled species showed strong statistical relationships with habitat, particularly macroalgae. The modelled species-environment relationships enabled us to infer the distribution of a subset of fish species across these understudied no-take zones. This study demonstrates the potential of discrete opportunistic studies using stereo-BRUVs for investigating the key drivers of community assembly in mesophotic marine environments.

Given <i>Austropuccinia psidii</i> (myrtle rust) mainly infects new growth, post-fire emergence of new epicormic shoots and seedlings is ideal for the development of the disease, leading to further loss of plants along with subsequent increase of fungal inoculum in the region. Extreme fire events across New South Wales and Queensland in 2019–2020 and subsequent vegetation regeneration across a wide area provided ideal conditions for disease epidemics. Surveys for myrtle rust were conducted across rainforest, coastal heath and woodland environments from south-eastern NSW to south-east Queensland 6–12 months post-fire. Myrtle rust was identified in all regions and ecosystems surveyed apart from areas in south-eastern NSW. Of the 73 Myrtaceae species surveyed in areas other than southern NSW, 44 were found with myrtle rust symptoms, ranging from small spots and limited damage to severe blighting, dieback and death of reshooting trees and seedlings.

Forest-dependent species face increasing challenges, including habitat loss, fragmentation and severe landscape changes, often resulting in population declines and local extinction. In this study, we investigate the effects of anthropogenic landscape changes—specifically fragmentation and native vegetation cover on—bird populations in the Atlantic Forest of northeastern Brazil. We hypothesise that (1) sites with pristine native vegetation will exhibit higher thresholds for local extinction compared to disturbed areas, even when large habitat fragments are present; (2) bird responses will vary based on land use patterns, landscape structure and forest dependence; and (3) many species will display distinct local sensitivity to environmental disturbances, diverging from global patterns reported in the literature. We collected data from 100 sites between 2012 and 2019, ensuring an even distribution across 10 classes of native vegetation. We assessed three bird attributes within a 1-km radius buffer around each site, using six landscape metrics. We recorded a total of 238 bird species, with 36 identified as highly sensitive. Our findings reveal that the most pristine areas support bird taxa that have already disappeared locally in other regions. Semi-dependent forest species appeared to benefit from reduced native vegetation cover. Moreover, our data unveiled unique local patterns of species sensitivity to environmental change. To safeguard Atlantic Forest birds in northeastern Brazil, we emphasise the importance of maintaining a minimum threshold of 60% native vegetation within the landscape, preserving fragments larger than 100 ha.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared changes in body condition and snout-vent length (SVL) of tuatara, and abundance of a host-specific, ectoparasitic tick for tuatara among sites, plus evidence for survival and emergence of the next generation of tuatara. We found a general increase in SVL and maintenance of body condition between release in 2012 and 2023 at all sites, with some differences between males and females. However, tuatara at some sites showed more growth and/or higher body condition by 2023, particularly correlating with site temperature. Although ticks persisted on founding tuatara, there were fewer ticks on the next generation and those at the southern site. Evidence for a second generation of tuatara was also weakest at the southern site.

We applied two correlative modelling approaches—model-selection procedures using MaxEnt and Ensemble Small Models—incorporating a broad suite of environmental predictors beyond traditional bioclimatic variables. Our results highlight that Ensemble Small Models outperformed model-selection procedures (MaxEnt) in predicting suitable habitats for these microendemic species, yielding more spatially precise predictions centred in highland, montane and submontane regions. Suitability was strongly associated with environmental variables related to precipitation and moisture, which play a critical role in shaping the realised niche of the <i>B. pernix</i> group.

This supports the hypothesis that mountain ranges act as long-term refugia during climatic fluctuations. Importantly, models incorporating heterogeneous environmental data outperformed those using only bioclimatic variables, highlighting the value of accounting for topographic and climatic complexity when modelling narrow-range taxa. Despite identifying additional suitable habitats, many of these areas remain unprotected and are increasingly threatened by deforestation and land-use change.
