Eucalyptus plantations (EP) have the potential to facilitate the regeneration of native species; however, in some cases, they may also hinder this process. The factors influencing the effects of EP on the regeneration of native species remain poorly understood. This study aims to identify the conditions that make these plantations favorable or unfavorable for the regeneration of native species. We investigated EP in agricultural landscapes in the south-eastern Malagasy highlands, located at the edge of dense rainforest. Floristic surveys were conducted in 20 EP situated at varying distances from natural forest fragments (near&lt;950 m, in forest edge; intermediate/far&gt;950 m in savannah). The understory of EP was characterised by a high abundance of native species. However, they were found to be more abundant and diverse in the intermediatestory of EP located near natural forest fragments. These native species are still in the early stages of plant succession, as they have essentially occupied the understory of the EP and contribute minimally to the basal area. The basal areas of native species in EP sites adjacent to natural forests are, in fact, comparable to those found in 0–5-year-old slash-and-burn fallows, which also occur on the periphery of natural forests. EP established in savannahs away from natural forests can act as catalysts for the natural regeneration of native species that would not occur without them. Conversely, EP on the edge of or within natural forests slow down the natural regeneration of native species, which would develop more rapidly in their absence. This study emphasises the significance of landscape spatial context in optimising the role of EP in the conservation and restoration of tropical forest ecosystems.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"60 ","pages":"Article e03631"},"PeriodicalIF":3.5,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941781","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}

Here, we examined alterations in density, species richness, community composition and life history strategy of oribatid mites following the transformation of tropical lowland rainforests into oil palm and rubber plantations in Jambi province, Sumatra, a region heavily affected by deforestation in Indonesia. Oribatid mites were sampled from litter and soil of four different land-use systems: rainforest, rubber agroforest (‘jungle rubber’), rubber and oil palm monoculture plantations. Oribatid mites in the litter layer more sensitively responded to changes in land use than those in soil, with density and species richness in rubber and oil palm plantations being significantly lower than those in rainforest. Community composition in rainforest and juggle rubber was similar, and distinct from that in rubber and oil palm plantations. In monoculture plantations, life history strategy of oribatid mites shifted towards parthenogenetic reproduction with larger genital plate, while sex ratio, egg number per female and body size were little affected. Soil pH and water content were identified as main drivers of community composition in both litter and soil, while soil microbial biomass correlated only with oribatid mite community composition in litter. Our results stress the critical role of plant litter in supporting oribatid mite communities in the face of land-use change. The similar community structure, life history strategies and environmental characteristics in rainforest and jungle rubber point to agroforestry as a promising management option to safeguard soil biodiversity in plantation systems.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"60 ","pages":"Article e03625"},"PeriodicalIF":3.5,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941782","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}

Subsequently, seeds from each treatment were collected and evaluated for their phenotypic characteristics and germination traits. We then conducted a five-month continuous monitoring of seedling survival, assessed their initial growth, and established a dynamic life table to track their development progress. Our findings revealed that self-pollinated <em>T. sinense</em> seeds exhibited inferior phenotypic traits, including decreased length, width, thickness, and 1000-grain weight, as well as lower germination rates and germination indices compared to seeds from the other pollination treatments. Furthermore, self-pollinated seedlings displayed shorter stems, smaller cotyledons, and reduced dry weights, but had longer taproots than cross-pollinated seedlings. They also showed lower survival rates and higher mortality rates than cross-pollinated seedlings. Analysis of the mortality density and hazard rate functions revealed a significant mortality peak and the highest failure risk at the two-month stage in <em>T. sinense</em> seedlings, indicating potential challenges during this period. In conclusion, our results indicate that self-pollination poses a significant threat to the survival of <em>T. sinense</em> by reducing seed genetic quality and seedling viability. Consequently, enhancing the genetic quality of <em>T. sinense</em> seeds through artificial cross-pollination could be a crucial strategy for promoting population renewal and supporting conservation efforts in the future.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"60 ","pages":"Article e03627"},"PeriodicalIF":3.5,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941780","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}

Because of their high sensitivity to even minor disturbance to natural habitats, orchid diversity is a key bioindicator of terrestrial ecosystem function. We evaluated orchid diversity in cemeteries of 13 European countries.

We propose that cemeteries are of major importance as refugia in conserving orchids in most of the visited European countries; however, one of the most urgent issues is to identify the many anthropogenic factors determining biodiversity of cemeteries, and to eliminate some newly emerged management practices in cemeteries that undermine biodiversity, including the orchid flora.

Overall, forests had higher soil and plant nutrient concentrations than grasslands. Soil N, K, and CEC increased with increasing dung counts across vegetation types, whereas plant K decreased with increasing dung counts only in Shorea forests and grazing lawns.

The aim of this investigation was to record the groundlayer diversity of grasslands found in northern Sumatra Island, Indonesia, and to determine whether that diversity was structured fire and mammalian herbivory. We sampled ten 50 m x 50 m vegetation plots in grassy vegetation across an aridity gradient, with soil data and grazing pressure data collected on site, and climate and fire frequency data compiled from geographic resources. We classified all species according to two morphological characteristics that related to plant evolution under fire and herbivory, namely stem form and leaf placement. We recorded 89 groundlayer species across all plots, with an average of 29 species per plot. Our analysis confirmed that the strongest axis of community differentiation was with respect to the fire-grazing trade-off axis, which selected for specific adaptive stem and leaf placement morphologies. The groundlayer diversity of grasslands in northern Sumatra is closely related to other monsoonal regions of Southeast Asia, likely reflecting grassland connectivity during the last ice age.
