Using quantitative text analysis, we evaluated 65 years of research on this iconic genus. Since 1960, research publications about the <i>Nothofagus</i> have steadily increased. Network analysis and structural topic models indicate that over this period, research activity has been concentrated on three broad themes: (i) long-term vegetation history and palaeoecology, (ii) forest ecology and management, with the latter becoming more prevalent over time, and (iii) the taxonomy and ecology of species associated with <i>Nothofagus</i>. Efforts to understand the long-term evolution, dispersal, and history of the group continue to inform debates about the biogeography of the Southern Hemisphere. Over time, there have been changes in the geographic patterns of research activity, with it becoming increasingly concentrated in South America since around 2000, with a commensurate decline in Australia and Aotearoa-New Zealand. This change in geographic activity is also associated with a shift in focus. Research in South America has increasingly addressed applied questions, including the potential response of forests with a <i>Nothofagus</i> component to climate change and questions associated with the silvicultural use of the group. Some outstanding research gaps remain, especially regarding our understanding of the ecology of the 19 tropical members of the genus, most of which are scarcely mentioned in the literature. A number of these tropical <i>Nothofagus</i> are of conservation concern, making this lack of basic ecological and distributional information alarming.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 10","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70130","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224122","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}

This research aimed to identify bird roadkill hotspots in semiarid environments, the spatial–temporal variation of roadkill hotspots, and which landscape variables are associated with them. Roadkill data were collected over 3–4 years on different roads. Ripley's <i>K</i> statistic—2D was used to verify aggregations, and HotSpot Analysis—2D to map critical points. Generalised Linear Mixed Models (GLMM) were applied to correlate hotspots with landscape variables, seasons and proximity to protected areas. It was detected that bird roadkill hotspots present significant spatial–temporal variation, and only 11 roadkill hotspots persisted for longer. It was also observed that hotspots are more frequent in agricultural environments as the distance from preservation areas increases, and they are more present in the rainy season. The great spatial–temporal dynamics of hotspots reinforce the need for long-term surveys and corroborate the findings that it is not advisable to implement mitigation measures based exclusively on hotspot analyses. Alternative approaches based on land use and occupation patterns and the relationship between species biology and habitat use should be considered in the management of road projects.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 10","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223795","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}

Diverse microbial communities have colonised different organs in various life forms, and their genetic diversity, and biochemical functions they perform, play a critical role in an organism's fitness and ecosystem status. The study of gut microbiota in marine organisms has gained increasing attention due to the critical role of gut bacteria in host digestion, nutrient metabolism and immune function. The Cape sea urchin, <i>Parechinus angulosus</i>, is the most widely distributed echinoid along southern Africa's coastline and inhabits coastal regions with contrasting oceanic physico-chemical features. The diversity of the gut-associated bacteria, spatial compositional variation across its distribution range, and the connection between host genomic diversity and gut microbiota are currently unknown. This study used a combination of 16S rRNA metabarcoding and ezRAD sequencing of host genomes to describe the diversity in Cape sea urchin and its associated gut microbiota. Bacterial taxa belonging to 20 phyla, 39 classes, 89 orders, 128 families and 191 genera were identified. While <i>α</i> diversity did not vary significantly within the bioregions inhabited by the sea urchin (west coast and south coast), <i>β</i> diversity indices revealed significant differences in bacterial community composition between individuals collected from the two bioregions. A distance decay analysis indicated a statistically significant correlation between geographical distance and dissimilarity in bacterial assemblage throughout the distributional range. Genomic analysis revealed no statistically significant population structure throughout the species' range. Similarly, after taking geographical distances into consideration, no statistically significant correlation between genomic distance and dissimilarity of bacterial assemblage was found, and the topologies of the genomic tree and clustering tree of microbial diversity were not concordant, showing that the factors that affect genomic structure in the host are not directly affecting their gut-associated microbiota. This study serves as a first stepping stone towards a better understanding of the role of gut-associated microbiota in Cape sea urchins and will help to enhance our understanding of the intricate relationships between marine organisms and their associated microbial communities.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 10","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223796","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}

Since the 1970s, there have been major changes in the science underpinning and general perspectives on relationships between logging and forest biodiversity conservation. Science has quantified the impacts of logging operations on biodiversity at a range of scales – from the tree to stand, landscape, and ecosystem levels. It has also highlighted deficiencies in the protection of forest biodiversity, resulting in an expansion of the protected area network in forests, as well as changes in the way forests are managed. In this paper, I briefly discuss some of the changes in the understanding of logging impacts on biodiversity over the past ~50 years, particularly in terms of the array of contributions made by the esteemed ecologist Jamie Kirkpatrick. These include his contributions to the following: (1) the development of new ways of identifying the most important areas as places to reserve; (2) assessments of the conservation values, including world heritage values, of particular areas; (3) forest management change via his rigorous scientific appraisals of forest policies and legislative instruments such as Regional Forest Agreements (RFAs). Just as there have been enormous changes in the management and conservation of Australia's native forests over the past 50+ years, there will likely also be large changes in the coming 10–50 years. On that basis, I conclude with some commentary on future prospects for forest biodiversity conservation in Australia.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 9","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70128","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146365","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}

Poor or misinterpreted data may lead to inefficient management and poor outcomes. Here, we review the disturbance ecology of an endangered plant and show that previous assumptions about its life history and disturbance response are incorrect. Wrinkled Buttons (<i>Leiocarpa gatesii</i>) is endemic to the Otway Ranges in Victoria, Australia. Once considered extinct, in recent decades it has increasingly been found colonising fuel breaks and disturbed track margins, where most known plants have been found. Track maintenance is identified as a threat in the species' National Recovery Plan, placing the agencies responsible for track maintenance in a difficult position. Existing information suggested that <i>L. gatesii</i> is a short-lived species that depends on a soil seed bank, released from dormancy by fire-related cues. In contrast, here we show that <i>L. gatesii</i> is a rhizomatous perennial, capable of re-shooting from fragments buried in soil moved by machinery. Its seeds germinate immediately with moisture and light, without promotion by smoke or heat. Comparison of transects on tracksides and within forests shows that <i>L. gatesii</i> is somewhat associated with tracksides, but not restricted to them, with many plants occurring in long-undisturbed forests. Plants on tracksides are more likely to be in flower, have more flowers per plant, and shorter stems, compared to forest plants. We suggest that the apparent extinction of <i>L. gatesii</i>, and the lack of records away from disturbed track margins, is a result of its low detectability when not in flower, rather than its disappearance into a soil seed bank. We discuss the practical implications of fire regime and track maintenance for the conservation of this species.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 9","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102091","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}

Globally, bryozoan habitats are rare and at risk from anthropogenic disturbance. This paper presents two newly described bryozoan habitats in Western Port (~70 km south-east of Melbourne, Australia) and further expands our current knowledge of bryozoan habitats in other parts of the bay. These previously unknown bryozoan habitats discovered in the North and Western Arms of Western Port are comprised of laminar forms that develop erect plates, growing large (up to 1 m in circumference and vertical relief) robust colonies and structure on cobble and shelly sand substrates in areas of high current and moderate wave energy. These bryozoan habitats are composed of two main species: <i>Adeonellopsis sulcata</i> (Milne Edwards, 1836) and <i>Celleporaria foliata</i> (MacGillivray, 1888). Colonies of <i>A. sulcata</i> and <i>C. foliata</i> were in approximately equal proportional abundance at the North Arm site, while <i>A. sulcata</i> dominated the Western Arm site. These bryozoan habitats support a variety of marine life, with sponges, ascidians, molluscs, echinoderms, fishes, cnidarians, smaller, non-habitat-forming bryozoan species and macroalgae recorded. The North and Western Arm bryozoan habitats differ from previously described bryozoan reefs in the Eastern Arm, which are dominated by fenestrate species forming erect rounded foliose colonies arranged in continuous linear rows and patch reefs in shallower areas of the bay. The new findings add to an emerging understanding of bryozoan habitats in Western Port (a Ramsar site of international significance), which are unique in their ecophysical setting and one of only four known such habitats in Australia.

Knowledge about early life stage dispersal remains limited, yet recent larval netting over two spawning seasons in the Macquarie River and adjoining irrigation channels fed by river pumps has revealed important insights. Freshwater catfish exhibited actipassive larval drift dispersal during a short spawning and nesting period in late austral spring to early summer (October–December), coinciding when water temperatures exceeded 21°C. Larvae (9.3–23.9 mm in standard length) were sampled in drifting ichthyoplankton nets set in the main flow of the river, as well as in adjacent irrigation channels. Sporadic low catch rates during the second season, likely due to flooding events, suggest potential disruption of nesting and spawning. Most freshwater catfish larvae were collected in overnight drift samples, indicating that drifting may be a nocturnal dispersal method. No larvae were captured in the still water areas using overnight light traps, further underscoring the potential importance of drift as a dispersal mechanism. The detection of frequent loss of larval individuals at unscreened pumps highlights a previously undocumented threat to the species during the larval life stage. Downstream larval drift contributes to the dispersal of early life stages of this species, but also increases susceptibility to entrainment at pump intakes and water diversions, which often operate at peak capacity during the larval drift period. Threats may be particularly pronounced in lowland rivers, where long reaches and higher levels of water extraction are likely to increase the risk of larval entrainment. This reinforces the need for modern fish protection screens at water diversions to mitigate this risk and help safeguard the future of freshwater catfish in the Murray–Darling Basin.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 9","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70124","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057728","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}

Here, hole punch growth measurements were conducted on tagged kelp plants to quantify these factors at multiple sites and in each season across 7° of latitude in New South Wales (NSW), Australia. Kelp biomass production varied among sites and among seasons, being higher over winter and spring than in summer and autumn and higher at Port Stephens than at Coffs Harbour, Batemans Bay and Eden. However, detrital production per plant, from kelp erosion and mortality, did not vary significantly among sites or seasons, although detrital production per unit area varied among sites with differences in kelp density. Overall, kelp growth and biomass and detrital production in NSW were comparable to those previously recorded in South Australia and Western Australia, although erosion was generally lower and mortality rates were generally higher than in Western Australia. This has important implications for management; the relatively uniform growth, biomass and detrital production across Australia indicates that, to maximise the blue carbon potential of kelp forests across Australia's Great Southern Reef, management should focus on preserving large, high-density kelp forests with high levels of detrital transport into deep offshore waters.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 9","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70120","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145038191","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}
