Special Issue Information

Dear Colleagues,

Global changes are profoundly reshaping the biodiversity patterns and community-building mechanisms of terrestrial ecosystems. Pressures such as climate warming, frequent extreme weather events, land-use transformation, and biological invasions are reshaping plant-animal-microbe trophic interactions through cascading effects, driving ecosystem functional transformations. This Special Issue focuses on the responses and adaptations of terrestrial biomes to global changes. Key areas of focus include (1) multiscale diversity dynamics: loss thresholds and maintenance mechanisms from genetic to landscape scales; (2) new paradigms in community building: trade-offs between environmental filtering, dispersal constraints, and ecological drift in disturbed environments; (3) trophic interactions: the feedback effects of food web restructuring on carbon and nitrogen cycles; and (4) ecosystem resilience: predictive models for restoration based on functional traits and phylogenetics. We encourage innovative research that integrates remote sensing, multi-omics, controlled experiments, and other interdisciplinary approaches to provide the theoretical foundation for biodiversity conservation and ecosystem management.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The genera Cortinarius and Russula are common ectomycorrhizal fungi, serving as excellent indicators of forest ecosystem health and soil conditions. This study conducted a systematic taxonomic investigation of macrofungi in the Huzhong National Nature Reserve of the Greater Khingan Mountains, integrating morphological and molecular phylogenetic analyses. Six new record species for China were identified: Cortinarius acutus, Phlegmacium balteatum, Cortinarius huronensis, Cortinarius lewisii, Cortinarius luteoornatus, and Russula grisescens. The article provides descriptions of their morphological characteristics and distribution, supported by phylogenetic analysis using ITS sequences. These findings expand the known distribution of these taxa to China’s taiga forests, reveal the region’s rich macrofungal diversity, and provide essential data for taxonomic, biogeographic, and forest ecosystem research.

Grassland productivity faces heightened uncertainty under nonlinear climatic forcing. This study characterizes the spatial heterogeneity of nonlinear variations and nonstationary climate sensitivities across the Eurasian Steppe Region (EASR) to provide a scientific basis for its adaptive management. Using the aboveground net primary productivity (ANPP) and climate datasets (1982–2015), we employed piecewise linear regression, LOWESS, and sliding window partial correlation analysis to identify temporal turning points and dynamic climate–productivity relationships. We identified distinct turning points in 1994 and 2008, revealing a phased “Increasing–Decreasing–Increasing” trajectory. A key novelty is the mapping of eight phased trajectory patterns, illustrating significant spatial heterogeneity in productivity trends. Furthermore, we demonstrate temporally reversed climate sensitivities. Notably, the sensitivity of ANPP to temperature shifted from positive to negative as warming-induced water stress intensified. While precipitation remains the dominant driver (68% of the region), its influence is nonstationary and state-dependent. In the Qinghai–Tibet Plateau, the limiting factor transitioned from thermal to water availability. Overall, productivity in the EASR appears to undergo phased reorganization under shifting climatic baselines. Our findings suggest that future ecosystem models should incorporate time-varying sensitivity parameters to account for nonlinear dynamics and potential trend reversals in grassland ecosystems.

The biosphere is undergoing critical transformations due to deforestation, agricultural expansion, and logging, which have led to biodiversity loss, degradation of ecosystem services, and climate change. In tropical forests such as the Ecuadorian Amazon, these pressures are especially severe because reductions in forest cover compromise key ecological processes. The purpose of this article is to analyze the relationship between shifting agriculture, food security, and conservation in the Ecuadorian Amazon, with emphasis on the agroforestry system known as the chakra practiced by Kichwa communities. This model integrates crops such as cacao, maize, and cassava with native trees, without chemical inputs, and constitutes a practice that is both culturally significant and environmentally sustainable. Whereas conventional shifting agriculture tends to reduce soil fertility and the forest’s regenerative capacity, chakras maintain important levels of floristic diversity, favor the conservation of endemic species, and provide ecosystem services such as carbon sequestration and nutrient regulation. In this sense, chakras represent a resilient yet context-dependent agroforestry alternative that connects food security and sovereignty, biological conservation, income, Indigenous identity, and climate-change mitigation, although their long-term sustainability remains influenced by market forces, land-use pressure, and policy support in tropical contexts.
