To better manage and promote resilience in threatened woodlands, we need to know more about the relationships between structure and diversity in these ecosystems. The influences of tree assemblage attributes on herb species have been investigated in forests, but such effects are poorly understood in more open woodland systems. This study aimed to determine how tree species richness, size class diversity and canopy cover influence native herb species richness and cover in coastal grassy woodlands of south-eastern Australia. Tree and herb composition and structure data were captured in 93 plots situated across the distribution of critically endangered Cumberland Plain Woodland. Bayesian models were used to elicit effects of trees on herbs. Where tree species richness was high, there were 28 % more native herb species on average, with both grasses and forbs contributing to the increase, and herb cover was 16 % higher. Tree size diversity increased native grass cover (by 19 %) but had no effect on forb cover or herb species richness. Native herb cover was 10 % lower under high tree canopy cover. In more recently disturbed woodlands, native grass cover increased under simulated thinning of dense, small tree regrowth, highlighting its potential as a conservation management tool. We found that species rich and structurally diverse canopy tree assemblages supported components of native herb species richness and cover in grassy woodlands.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"313 ","pages":"Article 111526"},"PeriodicalIF":4.4,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145271167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Here, we tested whether PAs serve as climate refuges for small ectotherms, the Australian <em>Lampropholis</em> skinks, by combining species-specific physiological data with biophysical modelling. We simulated environmental and physiological conditions across thousands of locations inside and outside PAs under present, +2 °C, and +4 °C climate scenarios to derive key thermal stress metrics — thermal safety margin (TSM), hours above critical thermal maximum (CTmax), and daily activity hours. Our results show that PAs can buffer skinks from heat stress by increasing TSMs, reducing exposure to temperatures above CTmax, and maintaining higher activity time under current and climate change scenarios. These benefits were strongest at low latitudes, where thermal stress is most intense, and varied among species depending on their physiological traits and ecological specialisation. Species with broader thermal tolerances experienced greater benefits from protection. Our findings demonstrate that PAs can mitigate climate stress in ectotherms, especially in tropical regions.

This study explores how plant palatability influences the epiphytic and endophytic microbiota of grassland plants and affects the gut microbiota of Brandt’s vole (<em>Lasiopodomys brandtii</em>), a key but declining herbivore in Inner Mongolian steppes. We analyzed the microbial communities of eight candidate food plants and the fecal microbiota of field and captive voles using 16S rDNA high-throughput sequencing. Results show that high-palatable plants (e.g., <em>Leymus chinensis</em>) had significantly lower endophytic bacterial diversity compared to low-palatable plants (e.g., <em>Cleistogenes squarrosa</em>). Low-palatable plants were enriched with Actinobacteria (24.66 %) and exhibited higher secondary metabolite synthesis capabilities, such as antibiotic production by <em>Pseudomonas</em>, potentially deterring herbivory. In contrast, high-palatable plants were dominated by Proteobacteria (98.45 %), including genera like <em>Ralstonia</em> which enhance plant digestibility, and suppress plant defenses to prioritize growth. Crucially, field Brandt’s voles consuming diverse plants show Bacteroidetes-dominated microbiomes for fiber digestion, while laboratory-reared voles on restricted diets develop dysbiosis with pathogenic Proteobacteria. Notably, 15 microbial phyla were shared between plant surfaces and vole guts, suggesting microbial transmission. These findings suggest a coevolutionary continuum wherein low-palatable plants utilize microbial defenses to resist herbivory, while high-palatable plants promote digestibility and vole attraction. This continuum shapes herbivore foraging behavior and nutrient cycling. We conclude that supporting diverse vegetation and microbe-mediated interactions is critical for conserving Brandt’s vole populations and maintaining ecological balance in grassland systems.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"313 ","pages":"Article 111504"},"PeriodicalIF":4.4,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145271456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

As the urgency to address biodiversity loss intensifies, the disappearance of species from their ecological niches poses increasing challenges for effective conservation management. This is particularly true for elusive species that have remained undetected for extended periods. Here we use limited locational data to build species distribution models (SDMs) for a threatened marsupial, the long-nosed potoroo (&lt;em&gt;Potorous tridactylus trisulcatus&lt;/em&gt;). In Gariwerd (Grampians National Park) the species has been rarely observed following the significant landscape impacts of multiple megafires and drought events. We developed a SDM from sparse historical data (&lt;em&gt;n&lt;/em&gt; = 17 records) to guide targeted camera trapping (2021–2024). Despite data limitations, the SDM facilitated the discovery of previously unknown extant populations. We iteratively refined our models through incorporating new field data, tracking parameter changes, and improving model fit. Final predictions identified suitable but currently unoccupied habitat that may be important for enhancing population resilience. We also performed connectivity analysis on habitat patches containing potoroos to estimate connectivity between extant populations and inform conservation planning. Our findings demonstrate the utility of preliminary SDM's, built on extremely limited data, as a starting point for managing rare and threatened species, enabling more targeted interventions to address threatening processes. Furthermore, our approach identified currently unoccupied suitable habitat critical for enhancing population resilience. These findings demonstrate the utility of SDMs, even with limited data, to direct surveys and identify key areas for proactive conservation strategies, including threat management and potential translocations, for data-deficient and declining species globally. Despite the utility of our models, we emphasise the critical importance of field validation and advocate for its inclusion as an essential step in distributional models.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Paper suitability: biological conservation&lt;/h3&gt;&lt;div&gt;The escalating biodiversity crisis, driven by anthropogenic pressures, necessitates innovative approaches to conservation management, particularly for elusive species where distributional knowledge is often severely limited.

We used a set of LED light poles placed along meadows in Freising, Germany, and placed sets of plasticine dummy caterpillars at different distances from the ALAN source, overnight, to measure predation between May and November 2024. We hypothesized that attack rates would be positively correlated with distance from the ALAN source, and that vegetation characteristics and moon phase would modify the impact of ALAN on predation rates. We found strong positive correlations between distance and total attack rates, arthropod attack rates, and a similar tendency in small mammals. Arthropod attacks were also significantly impacted by moon phase. We did not find any effect of distance to the ALAN source on slug attacks; their activity was evenly distributed in the landscape, but was significantly impacted by vegetation height. All groups were negatively impacted by a mowing event at the end of the season. Our results show that variability in ALAN in the lit environment can modify individual ecosystem functions, i.e., predation, in urban green landscapes, with variation at small spatial scales.
