Summary: Late'iki is a highly active volcano in the Tofua arc, with multiple eruptions in the past few decades. The most recent eruption in 2019 led to the formation of a temporary island, which was quickly eroded by waves. New observations show that the volcano summit is mainly composed of lava, with a thin layer of fragmented lava residue, possibly from hot rock-water interactions during the eruption.

Summary: This study presents the first theoretical modeling of joint Parker Solar Probe (PSP)-Metis/Solar Orbiter (SolO) quadrature observations. The results show that the observed solar wind speed and density are consistent with the theoretical predictions, and the slow solar wind is found to be highly Alfvenic. The study also demonstrates the similarity between theoretical and PSP measurements in terms of slab fluctuations and turbulence pressure.

Summary: The aim of this study is to investigate the morphology and dynamics of small-scale coronal plasma density inhomogeneities detected in the visible-light images of the Metis coronagraph on Solar Orbiter. The results show that the density inhomogeneities are small-scale structures with typical sizes of 500 Mm and 40 Mm. The enhanced density structures have longer lifetimes and more stable shapes as they travel outward. It is suggested that the plasma ejected in the reconnection process has a higher velocity than the ambient slow solar wind.

Summary: The study aims to predict the galactic cosmic-ray flux for the Solar Orbiter mission in order to evaluate the performance of the Metis coronagraph. By comparing observations with Monte Carlo simulations, it was found that cosmic rays only interact with a fraction of the pixel sample and the overall efficiency for cosmic-ray identification is linked to certain GCR particles. This analysis will continue throughout the Solar Orbiter mission for diagnostic purposes and potential long-term monitoring of the GCR proton flux.

Summary: Cyanobacterial toxins are found to disrupt the plant cytoskeleton and affect the structure and composition of the cell wall. This study investigated the alterations in cell wall matrix after treatments with cyanotoxins in rice root cells. The distribution patterns of homogalacturonan and arabinan were found to be altered, along with changes in pectin methylesterase activity. Increased intracellular Ca2+ levels, callose and mixed linkage glucans deposition were observed. The exact mechanism of cyanobacterial toxicity against the cell wall needs further investigation.

Summary: This study isolated and identified 15 Dunaliella strains from active and abandoned saltworks in Greece, which were classified into nine species based on morphological features. The phylogenetic analysis revealed distinct clades among different Dunaliella species, indicating that morphological features may not always align with phylogenetic relationships. The strains produced a low amount of beta-carotene under laboratory conditions. This study provides valuable information on the diversity of Dunaliella strains in Greek saltworks and highlights the need for further molecular data on Dunaliella spp.

Summary: This study investigated the taxonomy of the crustose lichen genus Calvitimela using molecular phylogenetics and morphological observations. The results revealed evolutionarily old and deeply divergent lineages within Calvitimela, with overlapping morphological characters between different subgenera. Chemical characters were informative at the level of subgenera but often homoplastic at the species level. A practical taxonomy of Calvitimela was proposed based on these findings.

Summary: This study investigates the evolutionary history and speciation mechanisms of montane potamids in the Hengduan Mountains Region. The results suggest that the vicariance events of these crabs are correlated with the emergence of sky islands due to the uplift of the mountains. The mountain ridges provided corridors for their dispersal and past climatic conditions played a crucial role in their evolutionary history. The mechanisms isolating sky islands are reinforced by the climatic features of dry-hot valleys and continue to affect local diversification.

Summary: This study investigates the phylogenetic relationships among patellogastropod families using mitochondrial and phylogenomic data. The results show that the mitochondrial phylogeny recovers monophyly of most families, but the relationships among families are still contentious. However, a more robust family-level topology consistent with morphology is achieved by phylogenomics. Additionally, the mainly deep-water families are found to be monophyletic, suggesting a single colonization of the deep water during the Jurassic.

Summary: Despite numerous studies on hybrid speciation, our understanding of this process remains limited. In this study, we conducted an 18-year systematic investigation on Populus taxa on the Qinghai-Tibet Plateau and discovered three new taxa that originated from distant hybridization between two different sections. These hybrid taxa demonstrate greater ecological adaptability than their ancestral species due to heterosis. We propose a hybrid speciation process model that can explain important evolutionary concerns.

Summary: Unlike conspicuous ochrophytes, many small and overlooked flagellates belonging to basally branching stramenopiles remain poorly characterized at the cellular or genomic level. This study describes four new species, including two new genera, of sediment-dwelling MAST-6 and provides updated phylogenomic tree of stramenopiles. The characterization of these flagellates is important due to their phylogenetic diversity and abundance in various environments.

Summary: Phylogenomic conflicts are widespread among genomic data, with most previous studies primarily focusing on nuclear datasets instead of organellar genomes. In this study, we investigated the phylogenetic conflicts within and between plastid and mitochondrial genomes using Potentilla as a case study. We found that both plastid and mitochondrial genomes divided Potentilla into eight highly supported clades, with two newly identified clades. Our results demonstrate that mitochondrial genes can fully resolve phylogenetic relationships among major clades of Potentilla and are not always linked with plastomes in evolutionary history.

Summary: Traditionally, differences between species have been associated with morphological variation. However, the discovery of cryptic diversity suggests that the evolution of distinct lineages can occur without morphological differences. Through genetic analysis, we found that a tropical montane plant lineage is composed of numerous unrecognized genetic groups that are not morphologically distinct. Geographic distance and topography play a crucial role in determining the genetic divergence of these groups.
