Therefore, in the present study, we aimed to analyse the microhabitat use and thermal ecology of <i>Gymnodactylus geckoides</i> in Catimbau National Park, in Pernambuco state, Brazil, considering different landscape conditions (anthropic and conserved), as well as environmental factors (body, air and substrate temperature, humidity and light intensity). We recorded bromeliads, leaf litter, as well as rocky outcrops, fallen trunks and rocks, with the use of microhabitats differing due to the environmental conditions. <i>G. geckoides</i> was mostly active at night, with substrate and air temperatures revealing a high correlation with body temperature. Regarding environmental factors, only light intensity revealed significant variations. The distribution model allowed us to observe <i>G. geckoides</i> inhabiting lower elevations, influenced by microhabitat availability. Our research represents the first effort to create a distribution model for lizards in Caatinga domain, using <i>G. geckoides</i> as an illustrative model to demonstrate the plasticity of species in response to environmental changes, also indicating a high dependency on habitat quality for thermoregulation. This domain provides <i>G. geckoides</i> with a thermally optimal and stable microclimate, maintaining its optimal body temperature requiring low thermoregulatory effort. Our results corroborate with previous studies and predictions and expand prior work regarding the thermal ecology of nocturnal neotropical lizards.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695787","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 New Zealand kauri, <i>Agathis australis</i>, is a foundation species that modifies its soil environment and, by doing so, it acts as an ecological filter selecting for a distinctive suite of plant species that co-occur preferentially with it. 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. Future studies should integrate longitudinal demographic data with disease progression to investigate the mechanistic effects of disease on kauri community dynamics.</p>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"50 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aec.70102","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144672007","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}

A total of 90 households were randomly selected for tree species inventory. Six transect lines were established for the inventory of tree species in study sites. Along each of the 3 transect lines, 15 quadrates were laid out. The total number of quadrates used was 90 (45 quadrates for each study site). Shannon, Simpson and evenness indices were used to calculate the richness and diversity of the tree species in the study area. From the study, the Shannon, Simpson and evenness diversity indices revealed that tree species richness per quadrate in both study sites was (1.84b ± 0.25) and (2.49a ± 0.14). This exposed the tree species; the Shannon, Simpson and Evenness diversity indices were higher at the Bohe site than at Bachira. The significant value index of individual tree species at parkland agroforestry was assessed, and <i>Croton macrostachyus</i> and <i>Cordia africana</i> were ranked first and second tree species in both studies sites with mean IVIs of 52.22% and 38.43%, respectively. This is recommended to farmers to increase the diversity and richness of tree species in their parkland agroforestry practice and reducing the charcoal market and needs further detailed investigation accordingly.

Although numerous demographic studies have been conducted, no comprehensive synthesis exists to identify gaps and achievements within this field for Arecaceae, which could guide future research efforts. This study provides an overview of current knowledge on Arecaceae demography. Through a systematic review, 59 demographic studies were identified, totaling 181 study cases.

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.

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.

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.

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 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.
