This study examines the effects of thinning retention density and stand structural variations on soil bacterial communities and metabolite composition in <em>Pinus massoniana</em> forests within degraded red soil regions of Changting, Fujian. High-throughput sequencing and non-targeted metabolomics were used to analyze bacterial diversity, metabolites, and their functional interactions with stand structure. The results showed that with increasing thinning retention density, bacterial richness (Sobs, Chao1, ACE), evenness (Pielou), and diversity (Shannon) followed the trend: T2000 &gt; T1600 &gt; T2700 &gt; T1200 &gt; T0. The relative abundance of Acidobacteria and Proteobacteria first increased and then decreased, whereas Chloroflexi declined. Bacterial community composition varied by thinning density: Chloroflexi dominated unthinned stands, Acidobacteria were most abundant in moderately thinned stands, and Proteobacteria were prevalent in higher-density thinned stands. Metabolomics identified 1188 metabolites, including lipids (18.7 %), organic acids (7.8 %), and phenols (7.8 %). Differential metabolites, such as L-selenomethionine, scopolamine, and isocitrate, were enriched in key pathways related to phenylpropanoid biosynthesis, secondary metabolite synthesis, and amino acid alkaloid production. Correlation analysis revealed that adenosine 3′-phosphate 5′-phosphosulfate and isocitrate were positively associated with Chloroflexi, while Tropinone and Seleno-l-methionine correlated with Proteobacteria. Overall, thinning alters microbial composition and metabolic pathways, reducing oligotrophic bacteria while promoting copiotrophic bacteria, and the decomposition functional metabolites such as L-selenomethionine and sinapyl alcohol decreased. These changes influence soil nutrient cycling and provide insights into sustainable forest management in degraded red soil regions.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"62 ","pages":"Article e03734"},"PeriodicalIF":3.5,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study leveraged data from 1739 vegetation plots from natural evergreen broad-leaved forests from the 2019 forest management inventory in Jiangxi Province, China. A boosted regression trees model was employed to assess regional effects on species richness, followed by the construction of a structural equation model (SEM) to elucidate the direct and indirect pathways of key drivers on tree layer species richness. The results revealed a tree layer species richness range of 3–17, with higher richness values predominantly in the northern, western, and southern regions. Species richness declined significantly with increasing latitude (<em>P</em> &lt; 0.05). About 40 % of the variation in tree layer species richness can be accounted for by the regional species pool (SP) and the selected regional environmental factors. The SEM revealed that SP, stand basal area per unit area (BA) and precipitation seasonality (PS) directly and positively affected tree layer species richness, while precipitation of driest quarter (PDQ) negatively affected richness directly. Tree layer species richness was affected indirectly by the anomaly in annual mean temperature from the Last Glacial Maximum to the present (Anomaly_RAMT) and regional annual mean temperature (RAMT) through SP, and by PDQ and precipitation of warmest quarter (PWAQ) through BA. Hence, conserving high-richness areas can help maintain elevated levels of biodiversity.

Forest specialists, such as shade-tolerant plants, are especially vulnerable to local extinction, whereas shade-intolerant species persist more in deforested landscapes. We conducted a field experiment across 39 Atlantic Forest landscapes to assess how forest loss affects sapling growth and survival along a forest cover gradient. We planted and monitored 2496 saplings from four tree species classified as shade-tolerant or shade-intolerant. Using path analysis, we evaluated the direct and indirect effects of landscape (forest cover), local (canopy openness) and sapling variables (leaf mass per area -LMA-, chlorophyll index, herbivory) on sapling performance. For shade-tolerant species, LMA emerged as the main factor influencing height growth, while basal area growth was primarily affected by canopy openness, determined by forest cover. In contrast, for shade-intolerant species, canopy openness—shaped by forest cover—was the dominant driver of both height and basal area growth. However, LMA, chlorophyll content and herbivory also influenced growth. Shade-tolerant species showed nearly double the survival rate of shade-intolerant species, with forest cover being the main driver of mortality for both groups. Our findings underscore the profound impact of forest loss on sapling growth dynamics and the survival of shade-tolerant and intolerant species. Moreover, they highlight a potential decline in forest resilience and the urgent need for restoration actions. Curbing deforestation and implementing restoration programs around existing fragments can be effective strategies to enhance sapling establishment and maximize ecosystem functionality in human-modified landscapes.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"62 ","pages":"Article e03730"},"PeriodicalIF":3.5,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144563473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 carried out automated 24-h video surveys to track strawberry flower visitors in three study sites in the region of Paris (France) with different surrounding land-use composition. We tested whether different flower visitor groups were active at different times of day (i.e. temporal complementarity vs. overlap), and whether foraging behaviour varied among groups and across the day. We found that most pollinators were active during the day, with ants reported as the main nocturnal flower visitors. Moreover, we found complementarity in the temporal activity of flower visitors in the least urbanised site. In contrast, in the more densely urbanised sites, a single peak of activity occurred during the afternoon, with dominance of honey bees, indicating overlap in temporal niche. We also found that the flower-visit duration varied substantially among pollinator groups, sites, and over the course of the day.

Here, we examined whether and how urban areas promote the persistence of a keystone, endangered endemic Mediterranean island lizard (<em>Podarcis pityusensis</em>) threatened by a rapidly spreading invasive snake (<em>Hemorrhois hippocrepis)</em>. By integrating field transects, citizen science data, snake trapping, and population dynamics models, we show that invasive snakes drive rapid lizard extirpation in natural areas, but urbanization buffers this effect, enabling local persistence. Intensive snake trapping revealed that urbanization hinders snake spread, acting as an ecological filter. Finally, population dynamics models show that, contrary to a source-sink model, urban lizard populations can persist in the mid-term without immigration, as surrounding peri-urban populations have collapsed under sustained predation pressure by the invasive snake.

We used a dendroecological approach to measure beaver occupation time and maximum browsing distance around 61 lakes. Around each beaver lodge, we established 1 m² plots along three transects in which we measured distance of browsing from shore and counted annual rings on coppices resulting from beaver presence.

Stable isotope analysis (δ¹³C and δ¹⁵N) of beaver carcasses collected from local trappers showed that the beavers’ diet included the consumption of conifer trees and a seasonal shift in food consumption. We found that lakes ranging from 4 to 20 ha were optimal for beavers, as this lake size mattered more than the availability of specific food sources. Beavers exhibited high adaptation skills by using different plant species depending on the season to maximize resource availability and energy cost trade-off.
