In the scenario of productive intensification, it is necessary to generate alternatives to model land-cover changes and their environmental consequences. This study aimed to generate land-cover projections and quantify the impact of these changes on ecosystem service supply in Uruguay. To achieve this, we used land-cover maps, Markovchain models and an ecosystem services supply index (ESSI). Transition probabilities between land-cover classes were calculated for two time periods (2000–2010 and 2010–2019) based on maps from 2000, 2010 and 2019. These probabilities informed two Markov chain models to project land-cover changes up to 2037. With the projected land-cover maps, spatial models were used to relate the proportion of croplands and grasslands with the ESSI. Our results indicate a continued expansion of croplands and afforestation over the coming decades, while grasslands will remain the dominant land cover, representing 46% of the landscape by 2037. Grasslands exhibited the highest probability of persistence in both periods, while croplands and afforestation increased their persistence probability by 60% and 13%, respectively. The ESSI shows a 5% decrease between 2000 and 2037. These findings highlight the ongoing transformation of Uruguay's landscapes and the potential trade-offs between land-use intensification and ecosystem services. The results provide valuable empirical evidence to support territorial planning and sustainable management strategies, helping to balance production needs with environmental conservation.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 8","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144888319","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}

An ex-situ experiment was conducted in which colonies of <i>Tubastraea aurea</i> were exposed to a continuous flow of seawater sourced from Guanabara Bay. During the experiment, colonies developed a Stress-Induced Mucus Aggregate (SIMA) that progressively enveloped the polyps and was associated with marked tissue loss upon removal. This response is distinct from the coral's typical mucus secretion and is hypothesised to result from environmental stress-induced alterations in the associated microbiota. The influx of organic matter and pollutants likely promotes a shift toward pathogenic and anaerobic microbial communities, which may further impair tissue respiration and contribute to coral mortality. 16S rRNA gene sequencing identified four ecologically significant bacterial genera—<i>Vibrio</i>, <i>Pseudoalteromonas</i>, <i>Alcanivorax</i> and <i>Shewanella—</i>commonly found in marine systems. These organisms demonstrate functional duality in coral microbiomes, simultaneously influencing both biofilm-mediated community assembly and disease dynamics. Their context-dependent roles markedly affect coral health outcomes under environmental stress regimes, highlighting their importance in reef ecosystem resilience. These findings suggest that microbial community dynamics in highly disturbed environments may play a key role in limiting the establishment and persistence of <i>T. aurea</i> in Guanabara Bay.

While its diet has been described in some regions, little is known about its population parameters, including its geographic distribution. Although traditionally considered endemic to the Cerrado, recent records from ecotone regions suggest its presence in other Brazilian biomes at enclaves of Cerrado or altered landscapes. This study presents new records of the hoary fox in two regions of <i>Zona da Mata</i>, Minas Gerais: Juiz de Fora and Viçosa, in areas originally covered by Atlantic Forest. In Juiz de Fora, two camera trap records were obtained in 2022, in an abandoned pasture near a small forest fragment. In Viçosa, a roadkilled individual was recorded in 2024. These records expand the species' known range 150 km eastward into the Atlantic Forest biome. The study areas have been historically subjected to forest conversion to agriculture, particularly exotic pastures, which may facilitate the expansion of species tolerant to open habitats, such as the hoary fox. It remains unclear whether these occurrences result from habitat transformations due to human activities or represent natural distributions. Understanding and updating the species' distribution is essential for estimating population size, assessing its responses to landscape changes and improving extinction risk assessments.

To achieve this aim, we analysed spatial changes in biodiversity and trophic structure, and explored their relationship with the main physical environmental variables. The study was conducted during spring 2021 and summer, autumn and winter 2022 in the south of Santa Cruz province, at sites with different salinity regimes and wave exposure. Different tidal levels and substrate slopes were compared. Data of abundance, richness and diversity of taxa and functional feeding groups were analysed and compared using univariate and multivariate statistics. Distinct macroinvertebrate assemblages could be recognised in the rocky intertidal of the study area, which were related to the different combinations of environmental variables. The salinity regime was the environmental factor most closely associated with the changes in the composition and diversity of the macroinvertebrate assemblage at a medium geographic scale. The macrotidal regime that characterises the region together with the particular geomorphology of its rocky shores highlights the effect of those variables that cause stress due to desiccation and exposure to extreme conditions. The main physical factors determining the diversity of taxa and feeding strategies at a small geographical scale are tidal level and substrate slope. Protection from waves favours the settlement of infaunal species and exotic species in sheltered rocky shores, where they find a more suitable and less stressful environment for their settlement. The results obtained are important for their biogeographic and ecological implications and provide relevant information for establishing management and conservation measures for coastal environments.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 8","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782619","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}

Kauri is threatened by kauri dieback disease caused by <i>Phytophthora agathidicida</i>. Despite kauri's ecological importance in structuring plant communities, little is known about the consequences of kauri dieback on the plant species ecologically associated with kauri—kauri associates. This study examined (1) the environmental drivers of diseased kauri occurrences, (2) the correlations between the occurrences of kauri associates and environmental factors and (3) which kauri associates frequently co-occurred with diseased kauri as a result of shared environmental responses. A joint species distribution model with nine environmental factors was used to analyse the occurrences of diseased kauri and 16 kauri-associated plant species located within a 10-m radius of 761 kauri trees in lowland kauri-podocarp-broadleaved forests of Waitākere Ranges, Auckland, New Zealand. Our results showed that diseased kauri occurred more frequently in sites at lower elevation, with shallower organic soil layers and a history of logging or timber processing disturbance. Additionally, successional strategies influenced the relationship between kauri associate occurrences and environmental factors, with kauri associates characteristic of early succession frequently co-occurring with diseased kauri due to environmental factors. This suggests that kauri dieback could either cause the retrogression of succession in kauri forests or that kauri in younger stands were more likely to be diseased. Both of these possibilities indicate that kauri dieback would likely change the successional trajectory of kauri forests.
