Aim
Quantifying the speed of invasive species range expansion and the mechanisms behind it is a key management goal that also informs ecological theories of spread. Byers et al. found that time since first global introduction (TSI) was the strongest predictor of non-native range size of coastal marine invertebrates relative to environmental and species traits, and species were predicted to expand on average 400 km/decade along coastlines. Here, one decade later using the same 138 marine invertebrates, we repeat that analysis and test the prediction that the average invader expansion speed was 400 km from 2014 to 2024.
Methods
Using the Global Biodiversity Information Facility (GBIF), we downloaded species occurrences to estimate the non-native range size of each invader along coastlines in the northern and southern hemispheres. We calculated expansion speed as the difference between each species' 2024 range size and its 2014 range size estimated by Byers et al. We tested (Hypothesis 1) TSI is still the most important variable for explaining global invasive range size; (Hypothesis 2) Mean expansion speed is 400 km/decade; (Hypothesis 3) Expansion speed is best predicted by distributional characteristics of a species' non-native range (i.e., initial range size, initial number of coastlines occupied); and (Hypothesis 4) Expansion speeds vary across taxonomic groups.
Results
TSI was still the best predictor of non-native range size (RVI = 1, β: 0.39–0.42). However, average range expansion speed since 2014 was 3000 km/decade, ~8× the previous prediction. Species that started with large ranges and distributions across multiple coastlines exhibited the fastest expansion speeds (R2 = 0.4), but there were no taxonomic patterns in expansion.
Main Conclusions
Ranges of non-native species are not at equilibrium and are still spreading rapidly, posing a challenge for coastal ecosystem management.

Aim
Using a widely distributed and frequently hybridising fish (genus Rutilus) in the Palearctic as a model system, we re-evaluated a series of hypotheses on phylogeny, taxonomy, phylogeography and the role of hybridization in evolutionary history based on the first large-scale analyses of nuclear SNPs together with mtDNA data obtained from all Rutilus species.
Location
Water systems in Northern Eurasia.
Methods
Based on nuclear (ddRADseq) data, we applied phylogenomic, population genomic and introgression analyses to assess the diversity of lineages, their distribution and hybridization in the context of the hypotheses tested.
Results
We identified 22 lineages in three major clades—Rutilus s. str., Leucos and Pararutilus. High diversity of lineages was discovered, with three revived species and three novel lineages of undescribed species in Europe. Evidence for extensive mito-nuclear discordance and ongoing and past inter- and intrageneric introgressive hybridization was found in many lineages. A Caucasian relic lineage and the endangered narrow endemic species ‘Rutilus’ atropatenus were found to represent an independent lineage (Orthroleucos) with a high level of past introgression with Rutilus.
Main Conclusions
The genetic structure of Rutilus revealed by nuclear SNPs contrasts markedly with that supported by mtDNA. Numerous mito-nuclear discordances are evidence of the past secondary contacts and highlight the weakness of taxonomy based on mtDNA alone. A super-lineage of mtDNA covering the range of many European, Siberian, Caucasian, and Central Asian Rutilus species (5000 km long) is a result of introgression of mtDNA from a widespread Ponto-Caspian lineage whose distribution likely pulsed with Pleistocene glaciation cycles. Anadromous life histories may have evolved in parallel in different clades and been facilitated by hybridization. The high plasticity, adaptiveness and species diversity of the genus Rutilus may be underlined by their heterogeneous genomes resulting from extensive interspecific hybridization. However, narrow-range endemic species may be threatened by introgressive hybridization.
目的以古北区分布广泛、杂交频繁的鹦鹉螺属（Rutilus属）为模型系统，基于首次大规模核单核苷酸多态性分析和所有鹦鹉螺物种的mtDNA数据，重新评估了一系列关于系统发育、分类、系统地理学和杂交在进化史中的作用的假设。欧亚大陆北部的水系统。方法基于核（ddRADseq）数据，应用系统基因组学、群体基因组学和基因渗入分析来评估世系的多样性、分布和杂交情况。结果鉴定出rutilus s. str.、Leucos .和Pararutilus 3大支系22个支系。发现了高度多样性的谱系，在欧洲有三个复活的物种和三个未被描述的物种的新谱系。在许多谱系中发现了广泛的核分裂不一致和正在进行和过去的基因间和基因内渐进杂交的证据。发现高加索遗迹谱系和濒临灭绝的狭窄地方性物种“Rutilus”atropatenus代表了一个独立的谱系（Orthroleucos），过去与Rutilus有高度的渗入。主要结论核snp揭示的贻贝遗传结构与mtDNA支持的遗传结构有显著差异。许多核分裂不一致是过去二次接触的证据，并突出了单独基于mtDNA的分类的弱点。一个覆盖了许多欧洲、西伯利亚、高加索和中亚贻贝物种（5000公里长）的mtDNA超谱系是广泛的本-里海谱系的mtDNA渗入的结果，该谱系的分布可能与更新世冰川旋回有关。雌雄同体的生活史可能是在不同的分支中平行进化的，并通过杂交得到促进。由于广泛的种间杂交而产生的异质基因组，可能突出了Rutilus属的高可塑性、适应性和物种多样性。然而，窄域特有种可能受到渐进杂交的威胁。

For several decades, substantial efforts have monitored cetacean distribution and abundance in the western North Pacific. Large-scale visual-based line transect surveys have been conducted since the early 1980s, covering almost the entire western North Pacific. However, information on distribution patterns of cetacean species is concentrated in summer months when sighting conditions are preferred, while dolphin fisheries, one of the main threats to cetacean populations, are conducted mainly during winter months.
Location
The western North Pacific.
Methods
To fill information gaps between these seasons and improve conservation and management measures, we compiled long-term sighting data. We constructed a simple species distribution model (SDM) to estimate the seasonal patterns for 14 delphinid and phocoenid species. Although the sighting data remained limited outside summer, the distribution probability was intra- and extrapolated to respective seasons using the constructed SDMs.
Results
Model fitting tended to be better for the species inhabiting higher latitudes than for those in lower latitudes. In addition, seasonal patterns observed in our habitat prediction maps roughly corresponded to those patterns previously reported from coastal fishers' logbooks and satellite-tracking records. The model also estimated that some species distribution changes in response to long-term warming in water temperature over the past 30 years.
Main Conclusions
The study addresses the seasonal gaps in conservation and management measures and improves understanding of population structures of the species targeted by dolphin fisheries. Our approach to predicting distribution patterns spatiotemporally is widely applicable to conservation systems for marine animals inhabiting dynamic ocean environments.

Aim
Niche conservatism and niche shift, as two opposing ecological processes influencing invasive species spread, pose challenges for developing management strategies in China. However, how these mechanisms interact during invasion remains unclear. We propose that this uncertainty stems from species traits and invasion histories. Specifically, compared to weak invasive and non-invasive alien plants, we hypothesize that vigorous invasive plants in China are more likely to exhibit niche shifts.
Location
China.
Methods
We quantified the niche dynamics of three categories of alien plant species in China using PCA and their driving factors, while simultaneously predicting their potential distributions with the MaxEnt model.
Results
Annual mean temperature (Bio1), maximum temperature of the warmest month (Bio5), and precipitation of the driest month (Bio14) were identified as key environmental variables. Most alien plant species exhibited strong niche conservatism. Vigorous and weak invaders showed higher niche stability, lower unfilling, and lower pioneering, whereas non-invaders displayed higher niche expansion, unfilling, and pioneering. The niche centroids of most species shifted toward warmer, drier, and lower-elevation areas with more intensive human activity. Longer residence time was associated with lower niche unfilling across all three species categories. Propagule pressure promoted niche filling in vigorous and weak invaders. Species with broader native ranges exhibited higher niche stability. MaxEnt models indicated that vigorous and weak invaders had extensive potential distributions, while non-invaders were more restricted.
Main Conclusion
The invasion success of alien plants in China mainly depends on niche conservatism and effective niche filling rather than extensive niche expansion. Long-term residence and strong propagule pressure promote the occupation of potential habitats. Native niche breadth has a positive effect on niche conservatism. These findings provide a scientific basis for the monitoring, risk assessment, and management of alien plants.

Aim
Climate change is driving species to either shift their ranges or face extinction. While its effects on taxonomic diversity (TD) are relatively well understood, the impacts on functional diversity (FD) and phylogenetic diversity (PD) remain less explored. Among the biological metrics considered in protected area (PA) selection, TD is the most common, yet its effectiveness in also capturing high FD and PD under future climate scenarios is uncertain. Here, we assess the implications of future climate scenarios for the conservation of TD, FD and PD of forest birds.
Location
Central Corridor of the Atlantic Forest (CCAF), Brazil.
Methods
We used ecological niche models to project the species distributions of 292 forest birds for baseline and future (2050 and 2070) scenarios. We generated binary maps of suitable areas for each species and calculated alpha and beta diversities for TD, FD and PD. We also evaluated spatial overlaps between highly diverse areas and the current PA network.
Results
Most species are projected to experience range contractions, leading to declines in TD, FD, and PD. The western CCAF, a subregion with low diversity, is expected to face the greatest losses, while coastal areas show greater resilience with fewer declines. FD and PD exhibit distinct spatial patterns, including functional type replacements in the northwestern CCAF and variations in phylogenetic lineages in the central-eastern subregion. Northeastern PAs may retain higher diversity in the future, while the southern CCAF remains underrepresented in the current PA network. The eastern CCAF is identified as a subregion of community stability across TD, FD and PD.
Main Conclusions
Incorporating multiple facets of diversity offers a comprehensive framework for conservation strategies. Beta diversity highlights critical stable areas connecting highly diverse subregions of the CCAF. Therefore, a better understanding of these patterns can guide the preservation of species, their ecological roles and evolutionary heritage in a changing world.

<div> <section> <h3> Aim</h3> <p>Understanding ecological niche shifts is crucial for predicting future changes under climate change. Modelling past niche dynamics provides a baseline for gauging the severity and direction of ongoing shifts. However, reconstructing historical habitats for data-limited, range-restricted species is challenging, as sparse species records hinder robust inference. We introduce and apply a hierarchical modelling framework to reconstruct historical habitats, assess niche shifts over time, and estimate prediction uncertainty for data-limited species. We applied this framework to the Sierra Nevada Grey-crowned Rosy-Finch (<i>Leucosticte tephrocotis dawsoni</i>) to evaluate changes in breeding habitat suitability under climate change.</p> </section> <section> <h3> Location</h3> <p>Alpine regions of California, USA.</p> </section> <section> <h3> Methods</h3> <p>We applied a hierarchical habitat selection approach based on three orders. Available habitats of finer orders were selected based on insights from broader orders. For each covariate we defined a range of nested scales of effects and employed indicator variable selection and spike-and-slab priors for variable selection. Historical niche relationships (1954–1980) were used as priors alongside current survey and bioclimatic data to characterise present-day suitable habitats (2018–2022), estimate niche shifts, validate models and assess conservation implications.</p> </section> <section> <h3> Results</h3> <p>We found substantial habitat declines, with suitability contracting by 40%–64% across habitat selection orders and suitable breeding areas shifting upslope by approximately 280 m. Historically, suitable habitats were characterised by rugged, high-elevation terrain with persistent snow. Contemporary distributions show reduced topographic constraints but increased reliance on diminishing snow resources, suggesting potential niche expansion.</p> </section> <section> <h3> Main Conclusions</h3> <p>Our approach effectively identified key variables across habitat selection orders, revealing both niche contraction and expansion driven by reduced snow persistence, processes likely affecting many alpine species globally. This framework offers a robust tool for characterising habitat changes for data-limited species, with broad applicability for conservation planning.

Modelling past niche dynamics provides a baseline for gauging the severity and direction of ongoing shifts.

We introduce and apply a hierarchical modelling framework to reconstruct historical habitats, assess niche shifts over time, and estimate prediction uncertainty for data-limited species.

Aim
Despite their extent (40° of latitude and 50° of longitude), research in African savannas is dominated by a few heavily studied areas. We gathered data from African savanna protected areas to (i) evaluate their contributions to the primary literature, (ii) identify environmental groupings with respect to climate, soils, and landscape variables, and (iii) analyze the determinants of tree cover and fire within groupings.
Location
Africa.
Methods
We extracted climate, soil, topography, hydrology, elephant, fire, and tree cover data from polygon boundaries for 244 African savanna protected areas. The polygon layers and data were assembled into a novel geodatabase: African Database of Savanna Protected Areas (ADSPA). Cluster analysis identified natural bioclimatic groupings and structural equation modelling was used to analyse and compare the drivers of fire and tree cover within and across clusters.
Results
Previous literature disproportionately focused on a few savannas: 46% of savanna publications came from 2% of protected areas. Cluster analysis identified five bioclimatic groups: (1) African hot mesic savannas, (2) African cool mesic fertile savannas, (3) West African hot semi-arid savannas, (4) Southern African semi-arid savannas, and (5) Kalahari arid savannas. Current savanna science in protected areas is biased toward the Southern African semi-arid and African cool mesic fertile savannas, while hot mesic, hot semi-arid, and arid savannas are underrepresented. Climate and soils were strongly associated with tree cover and fire across protected areas, but no significant biome-wide effects of fire on tree cover emerged. However, tree cover was negatively related to fire in the hot mesic savanna cluster.
Main Conclusions
Significant biogeographic and ecological variation within African savannas highlights the need for research across the entire breadth of the biome, especially West Africa. We stress the need for spatially explicit, Africa-wide, data on mammalian herbivore biomass to better assess the importance of this variable for savanna functioning.

Aim
No or unlimited dispersal capacities of species are commonly assumed in species distribution models (SDMs) used to assess potential impacts of climate change on biodiversity. However, these assumptions may lead to overly pessimistic or optimistic predictions. We aim to assess how outputs of broad-scale SDMs of plants based on species-specific dispersal estimates compare to outputs based on no and unlimited dispersal assumptions under climate change.
Location
Europe.
Method
We developed SDMs using occurrence records of 1318 vascular plant species in Europe and predictor variables representative of climate, soil and topographic conditions. We used the SDMs to project species to 2071–2100 for two climate scenarios (mild and severe climate change) combined with three dispersal assumptions: species-specific, no dispersal, and unlimited dispersal. We then calculated the range sizes, species richness, and changes in both for each combination.
Results
Range size changes and species richness changes based on species-specific dispersal estimates generally approximated those under the no dispersal assumption in both climate scenarios. This reflects that the majority of the species in our sample have a limited capacity to disperse. Only for the minority of species dispersed by wind or animals did the incorporation of species-specific dispersal estimates result in clearly smaller projected range losses compared to the no dispersal assumption. However, also for these species the assumption of unlimited dispersal was generally too optimistic.
Main Conclusions
We found that many plant species considered in our study have a limited capacity to disperse beyond their current range under climate change. We recommend incorporating species-specific dispersal estimates in broad-scale SDMs of plants, to reduce uncertainties in species distributions projected under climate change. In the absence of this information, we recommend assuming no dispersal capacity for species with low dispersal rates, because the assumption of unlimited dispersal leads to considerably overestimated future range sizes and species richness.
