    Accurately predicting the potential distribution of Setaria palmifolia in China is crucial for assessing its climatic adaptability as a forage resource and for developing sustainable utilization strategies. This study systematically integrated 927 species distribution records while employing a comprehensive set of multidimensional environmental variables, including climate, topography, vegetation, and human activity. Using an optimized Maximum Entropy (MaxEnt) model, we simulated the potential geographic distribution of S. palmifolia under both current conditions and future scenarios (2050s, 2070s, 2090s) across three Shared Socioeconomic Pathways (SSP126, SSP370, SSP585). The results identified the key environmental factors influencing its distribution: precipitation of the warmest quarter, precipitation of the coldest quarter, and temperature diurnal range. These factors collectively contributed 93.4% to the model. Under current climatic conditions, the total potentially suitable habitat for S. palmifolia is approximately 177.22 × 104 km2, primarily concentrated in southern China. Future projections indicate that the total suitable area will remain relatively stable across all scenarios (ranging from 177.22 × 104 to 196.80 × 104 km2). However, its internal structure will undergo significant reorganization, with highly suitable habitat expanding from 12.20 × 104 km2 (current) to between 29.69 × 104 and 50.39 × 104 km2 depending on emission scenarios. By the 2070s, this expansion is projected to reach 35.80 × 104 to 50.39 × 104 km2. Meanwhile, the distribution centroid shows complex, non-linear migration trajectories. This internal suitability reorganization pattern suggests that S. palmifolia responds to climate change through local adaptation rather than simple range shifts. Our findings provide critical scientific evidence and spatial decision-support for regional introduction planning, priority conservation area identification, and climate change adaptive management of S. palmifolia as a forage resource.

    Background: The Norwegian lemming (Lemmus lemmus) is a small rodent endemic to the Fennoscandian alpine and arctic tundra. The species is known for cyclic population outbreaks and mass movements during peak years. Previous research based on microsatellites revealed high genetic variation but a weak population structure in the Norwegian lemming. Results: In this study, we revisit the population structure of the species using genome-wide data. To do this, we generated a high-quality de novo reference genome for Lemmus lemmus, and resequenced genomes to 2.5–5 × coverage, from 86 lemmings sampled across the species’ entire geographic distribution. Our results reveal that the population is geographically structured into distinct subpopulations, with an overall pattern characterised by isolation-by-distance among subpopulations. Furthermore, our results are consistent with earlier work suggesting that the species survived the last ice age within a northern refugium. Conclusions: Together, these findings provide a genome-wide perspective on today’s population structure of the Norwegian lemming. In addition, we provide a de novo reference genome, which we believe will be a valuable resource to the research community.
  • Patterns of helminth parasite infections in cyclic common vole (Microtus arvalis) populations

    Journal of helminthology (Cambridge University Press, 2026)
    Research on parasite-induced regulation has identified the conditions under which parasites can destabilise host population dynamics: high levels of aggregation, delayed density-dependence, and moderate negative effects on fitness (reproduction, survival). Gastrointestinal helminths with direct life cycles and a single definitive host provide ideal systems to test these predictions. In this study, we first determined which helminths infect common voles (Microtus arvalis) in NW Spain, where populations are cyclic. We showed that the helminth community is dominated by Syphacia sp., a gut-restricted, directly transmitted nematode. We then examined how the prevalence and abundance of Syphacia sp. varied with host sex, season, and population cycle phase (increase, peak, or crash), and tested if vole condition (relative body mass and organ hypertrophy) and female fecundity (litter size) correlated with the prevalence of Syphacia sp. Infections were highly aggregated in Syphacia sp. and parasite abundance peaked during the crash phase of the vole cycle. We found that vole condition did not vary with the prevalence of Syphacia sp., but vole litter size showed a season-dependent association, with infected females producing smaller litters in spring and summer. These findings suggest that even low-pathogenic, directly transmitted parasites could exert reproductive effects, potentially shaping host population dynamics in combination with ecological and demographic factors. Experimental approaches are required to clarify causality and potential regulatory feedback.
