Fromm et al. and Vernier et al. suggest that their analyses of satellite measurements indicate that the main part of the Nabro volcanic plume from the eruption on 13 June 2011 was directly injected into the stratosphere. We address these analyses and, in addition, show that both wind trajectories and height-resolved profiles of sulfur dioxide indicate that although the eruption column may have extended higher than the Smithsonian report we highlighted, it was overwhelmingly tropospheric. Additionally, the height-resolved sulfur dioxide profiles provide further convincing evidence for convective transport of volcanic gas to the stratosphere from deep convection associated with the Asian monsoon.

Denisovans contributed notably to the genomes of present-day East and Southeast Asians. However, the relationship between the inhabited paleohabitats and the adaptive genetic traits related to infections in modern humans remains underexplored. This study uses geospatial techniques to analyze climatic factors associated with three Denisovan archaeological sites linked to nine specimens.

Most studies on modern Asian monsoon formation focus on mechanisms arising within the Afro-Eurasian continent, while fewer compare the effects from remote continents. Here, we explore this question using a coupled climate model. We show that the existence of the North American continent is critical for the intensity of the Asian summer monsoon.

Both biotic and abiotic factors are expected to drive species diversification, yet demonstrating their synergistic effects within a single framework is challenging and has rarely been studied. The recent and rapid radiation of the genus Aspidistra (cast-iron plant) provides an ideal system for examining these processes. Here, we generated restriction site-associated DNA sequencing data for 123 Aspidistra taxa and reconstructed well-resolved phylogenies using both concatenation- and coalescent-based approaches.

Understanding the evolutionary history of the Eurasian steppe is crucial for restoring severely degraded ecosystems and mitigating the impact of future climate change. Stipa species, which demonstrate zonal and extrazonal distribution patterns across the eastern Eurasian steppe, serve as a noteworthy example for elucidating the evolution of this biome. In this paper, we explored the phylogeny of the genus Stipa using transcriptome data, while examined the genetic differentiation, demographic history, and adaptive evolution of S.
