Aim
Understanding the mechanisms shaping biodiversity patterns, particularly the role of community assembly processes, remains a central challenge in ecology. In this study, we examine how climate and anthropogenic pressures jointly drive community assembly and biodiversity patterns through taxon co-occurrence analyses.
Location
Southwest China, East Asia.
Taxa
Chironomids.
Methods
Spatial chironomid data from 129 lakes (3297-m elevational gradient) across southwest China and a century-scale subfossil chironomid record from an alpine lake, Tiancai, were used to assess taxon co-occurrence and biodiversity patterns across space and time, and linked to environmental drivers including climate and human impact.
Results
Spatially, chironomid richness exhibited a unimodal elevational pattern, peaking at mid-elevations (3011–4014 m a.s.l.) where co-occurrence was minimised; conversely, both low- (1291–2988 m a.s.l.) and high- (4022–4588 m a.s.l.) elevation lakes showed reduced richness and elevated co-occurrence. It shows that key environmental proxies diverged, that is, human activity intensity, temperature and nutrient level declined with elevation, water transparency increased while productivity and environmental heterogeneity peaked mid-elevations. Temporally, at mid-elevation Lake Tiancai, richness declined since the 1990s while co-occurrence, evenness and variability increased, driven predominantly by rising temperature, with rare taxa and specialists accounting for the vast majority of taxon loss.
Conclusions
Our findings reveal elevation-dependent biodiversity mechanisms: Human disturbance dominates richness patterns in low-elevation lakes, while climate warming disproportionately threatens rare and narrowly distributed taxa at mid-elevations. Critically, an inverse richness-co-occurrence relationship persists across spatial (low/mid elevations) and temporal scales, where elevated co-occurrence signals environmental filtering that constrains local biodiversity. Conservation strategies must, therefore, prioritise protecting heterogeneous habitats to mitigate biotic homogenisation and sustain vulnerable taxa.

Aim
Studies assessing changes in vegetation with climate change have not separated atmospheric and water shortage stresses, although they drive different vegetation patterns in relation to continentality, water balance and bedrock types. We aim to assess how these two stresses will likely impact forest communities.
Location
European Alps.
Taxon
Angiosperms and Conifers.
Methods
We selected from the literature 773 forest plots that were sampled for vegetation composition during the 20th century. We collected at each plot climate variables from databases and calculated several climate indices (including winter rainfall continentality and summer water balance) at two periods (1965–1994 and 1995–2024). We conducted a canonical correspondence analysis (CCA) on the vegetation (understory species) and environmental tables (including eight 1965–1994 climatic variables and bedrock type, exposure, and canopy cover). The significance of differences in climate conditions between the two periods was tested separately for each climate variable and each of the 19 community types identified by a cluster analysis conducted after the CCA.
Results
Elevation, continentality and bedrock were the three primary complex environmental variables affecting temperature, atmospheric and water shortage stresses, factors directly driving vegetation composition. Climate change induced an overall decrease in summer water balance and an increase in temperature and continentality. However, a stronger increase in water shortage stress was observed for high elevation sites from northern latitudes with a high summer water balance, while a slight decrease in atmospheric stress was observed for summer-dry continental communities from the southwestern French and Italian Alps.
Main Conclusions
Atmospheric and water shortage stresses have specific effects on forest community composition and therefore need to be accounted for when predicting changes in vegetation composition with climate change.

The availability of genomic and genetic data is fundamental to advancing biogeographical research, particularly in biodiversity-rich but data-poor regions such as the South Atlantic. Yet, despite increasing mandates for open science, researchers face significant barriers to accessing datasets from published studies. While some authors may withhold data due to legitimate concerns about intellectual property protection, ongoing analyses, or conservation purposes, these situations should be clearly justified. Otherwise, prolonged or indefinite data restriction, manifesting as missing accession numbers, incomplete metadata, withheld sample information, poor geographic localisation, or even demands for co-authorship as a condition for data sharing, undermine transparency, reproducibility, and scientific progress. We argue that such practices constitute more than technical oversights. They represent structural and ethical obstacles that undermine transparency, reproducibility, and scientific progress. In this perspective, we aim to underscore the relevance of this discussion in the context of biogeography. To test biogeographic hypotheses using published data, particularly in comparative analyses, genetic data must be properly georeferenced and accompanied by accurate taxonomic identification. We emphasise that requesting data is not an attempt to appropriate or diminish the merit of the original work. Rather, it is a means of amplifying its value through new analyses and the generation of novel insights that remain grounded in proper attribution and collaboration. We call upon journals to strengthen data-sharing policies and enforce compliance. We urge institutions to redefine ethical standards around data availability. We also advocate for funding agencies to treat open data as a core metric of research impact. Without a collective shift in culture and responsibility, science risks falling short of its ideals. Data are not academic currency. They are the foundation upon which science must stand.

Aim
Southern China was not directly affected by large continuous ice sheets during the late Pliocene to the Quaternary period, thus playing a central role in shaping the biodiversity distribution patterns of species globally. While numerous phylogeographical studies have focused on three subkingdoms: the Qinghai-Tibetan Plateau (QTP), the Sino-Himalayan Forest and the Sino-Japanese Forest, research on the formation of plant diversity in South China is limited. This study aims to investigate the drivers of plant diversification in southern China by elucidating the evolutionary history of the endemic selfing herb Caulokaempferia coenobialis.
Location
Southern China.
Taxon
Caulokaempferia coenobialis (Zingiberaceae).
Methods
We analysed the evolutionary history of C. coenobialis by sequencing 11 chloroplast regions and three nuclear genes from 145 individuals across 15 populations, as well as assembling 29 plastid genomes.
Results
C. coenobialis exhibits high genetic diversity at the species and regional levels, with low population genetic diversity and significant inter-population differentiation. All populations diverged into two major lineages located in Southwest and South China approximately 2.75 Ma, after which the South China lineage diverged into two sublineages in Southern and Northern South China approximately 1.21 Ma. These two divergences coincided with the Karst development between Southwest and South China and the transgressions and regressions in South China during the Pleistocene.
Main Conclusions
The Pleistocene monsoonal climatic fluctuations, the tectonic activity of the southeastern boundary fault of the QTP, the resulting development of Karst landforms and the transgressions and regressions in South China shaped the phylogeographical pattern of C. coenobialis. The study offers new insights into the effect of Pleistocene climatic fluctuations and neotectonic movement on the genetic isolation and population differentiation of plant species in southern China. It also offers practical implications for achieving the ‘30 × 30’ target of the Kunming-Montreal Biodiversity Framework.

Range size constitutes a fundamental characteristic of every species and is commonly believed to influence diversification rates. This relationship is potentially dependent on the mode of speciation and other intrinsic factors, including geographic setting and species attributes. Yet, not only the size of the geographic range, but also the heterogeneity of environments it comprises, including its vertical extent (elevational range size) can affect speciation and extinction processes. For instance, mountain species and those whose range encompasses only one ecoregion (specialists) are expected to show higher diversification rates than lowland and generalist species. This study aims to investigate the link between range size, niche specialisation and diversification rates in a speciose bird superfamily that occurs throughout the Americas.
Location
America.
Taxon
The Tyrannoidea superradiation.
Methods
We employed a suite of phylogenetic methods including phylogenetic generalised least squares regressions, ancestral reconstructions and multiple-states speciation-and-extinction models.
Results
We observed a triangular pattern in the relationship between geographic and elevational range size, indicating that while species with a broad elevational range generally also have a large geographic range, the opposite is not necessarily true. The strong support for the BAYAREALIKE + j model, along with the negative association between range size and diversification rates, suggests that the predominant mode of speciation in this system is likely parapatric speciation, where divergence arises due to steep environmental gradients or local adaptation. Species inhabiting only one ecoregion and mountain species exhibited higher diversification rates than generalists and lowland species.
Main Conclusions
Reconstruction of ancestral geographic ranges and habitat supports the idea that the colonisation of open environments that proliferated in the Miocene fueled the diversification of this superfamily. The absence of a positive relationship between range size and diversification may explain the low conservatism observed for the analysed spatial traits
