Summary: This study investigates the evolutionary features and phylogeny of Pinus species using the complete plastid genome. Thirteen hotspot regions are identified as potential genetic markers for determining phylogeny and population genetics analysis. Seven genes with positive selection sites in Pinus species are also identified. The study reveals that Pinus species originated around 100 million years ago and two subgenera originated around 85.05 million years ago.

Summary: This study reveals the genetic origin of Japanese wolves by analyzing ancient DNA. The findings show that the Pleistocene wolf was not a subspecies of the Japanese wolf, but belonged to an earlier-diverging lineage, while the Holocene Japanese wolf was a mixture of the Japanese Pleistocene wolf and continental wolf lineages.

Summary: This study sequenced the complete chloroplast genomes of six Paphiopedilum species and identified ten highly variable regions that could serve as potential DNA barcodes or phylogenetic markers. The results also demonstrated that chloroplast genome sequencing is an effective means in resolving the complex relationship in Paphiopedilum.

Summary: The current sea level rise and an increase in the frequency and severity of sea storm events will have important environmental impacts on coastal tourist areas in oceanic islands. This study analyzes the current and future conditions of southwest sea storm events and their effects on tourist zones using mapping and high-resolution data. The results show an increase in the frequency of events, especially since the 1990s.

Summary: Lava caves, tubes, and fumaroles in Hawai'i have unique bacterial communities with little overlap between different caves or sites. Older lava tubes have higher phylogenetic diversity compared to younger or geothermally active sites. Competitive exclusion is the main driver in structuring the bacterial communities in Hawaiian volcanic environments.

Summary: This study investigates nitrogen dynamics in the Hawaiian Archipelago using macroalgal tissue parameters. The results show that in the Main Hawaiian Islands, macroalgal tissue stable N isotope ratios are higher in mesophotic depths, while N content is higher in shallow depths. However, in the Northwestern Hawaiian Islands, no differences in stable N isotope ratios and N content were found between shallow and mesophotic depths. Regionally, stable N isotope ratios vary along a gradient of anthropogenic and oceanographic processes.

Summary: This review of 157 studies on radiometric dating of glacial deposits in the Mediterranean reveals a greater complexity in the timing of Pleistocene glaciation than previously recognized. Evidence from various dating methods suggests that glaciers existed throughout the Late Pleistocene and even extended into the Middle Pleistocene in the region. Glacial activity in the Mediterranean mountains shaped the landscape significantly, and the deglaciation trend has continued into the Holocene with some small glaciers remaining today.

Summary: This study systematically reviewed and updated the cephalopod species diversity in the Canary Islands, revealing 85 confirmed species, representing approximately 10% of the overall known cephalopod diversity globally. The cephalopod community in the area was dominated by oceanic species, with shelf-slope and coastal species also present.

Summary: The swimming speed of sperm is negatively correlated with total sperm length and relative midpiece length, but does not correlate with relative flagellum length in Canary Islands chiffchaff populations. Mitochondrial DNA differentiation was confirmed between Gran Canaria and other islands. The study adds to the evidence that passerine birds do not support sperm morphology-swimming speed hypotheses and suggests that predictions from mammalian hydrodynamic models should not be applied to this taxon.

Summary: The role of recycled carbonates in Hawaiian volcanism is studied by analyzing the compositions of lavas from different stages. It is found that the rejuvenated stage lavas contain a significant amount of CO2, indicating a CO2-rich mantle source. The temperature of the rejuvenated primary magma is similar to that of the shield stage, suggesting that the carbonated melts responsible for the rejuvenated stage lavas likely originated from the melting of carbonated peridotites in the plume. This study provides important insights into the contribution of recycled carbonates to volcanic activity.

Summary: The study conducted an evolutionary genomics analysis of genus Metrosideros, a landscape-dominant adaptive radiation of woody plants in Hawaii. It was found that Hawaiian Metrosideros originated from a single colonization event and showed evidence of extensive reticulation and admixture between taxa. Divergent selection was identified as driving the formation of differentiation outliers in early stages of speciation/divergence.

Summary: The research synthesizes studies of apomixis in ferns and presents a six-stage model for the evolution of obligate apomixis. It highlights the role played by drought and associated abiotic conditions in the establishment of this reproductive strategy, with an increase in the frequency of apomixis observed among taxa inhabiting dry North American deserts. The findings reinforce the strong association between abiotic factors, particularly water limitation, and obligate apomixis in ferns.

Summary: Recent studies of plant RNA editing have shown significant variation in editing sites among different taxonomic groups, with ferns remaining largely unexplored. By analyzing the RNA editing in two Adiantum species and comparing them with a previously studied species, it was found that there is variation in both the number and location of editing sites among the species, with U-to-C editing sites showing higher conservation than C-to-U sites, especially those affecting start and stop codons. This suggests that RNA editing can evolve rapidly within Adiantum species, with certain types of edits potentially conferring selective advantages.

Summary: Ongoing research has led to the discovery of a new species, Cheilanthes ecuadorensis, from the taxonomically complex genus Cheilanthes in Ecuador. Despite its superficial similarity to C. pilosa, molecular analysis shows that C. ecuadorensis is actually more closely related to C. micropteris. This study underscores the significance of herbaria in the process of discovering new species.

Summary: This study summarizes 130 years of collections-based research on the ferns and lycophytes of Glacier National Park and documents the changes in flora understanding over time. By conducting field surveys and online herbarium studies, the authors confirmed a total of 71 fern and lycophyte taxa for the Park, with most previously unreported taxa belonging to the Botrychium genus.

Summary: Myriopteris scabra is a xeric-adapted fern species, endemic to the southwestern United States and northern Mexico. This study reveals that M. scabra consists of two genetically disparate, morphologically recognizable taxa, with little or no geographic overlap. The tetraploid taxon, named M. grusziae, replaces diploid M. scabra in the northeastern portion of its range, and is most similar to M. scabra but with distinct morphological differences.

Summary: Previously published evidence suggests that Draba maguirei may represent a species complex rather than a single species. A systematic study reveals the existence of three distinct lineages within D. maguirei, with each lineage having different chromosome numbers and occupying different geographic ranges. The clarification of the diversity and distribution of these taxa is important for conservation efforts.

Summary: Anthropogenic climate change poses a threat to the survival of Gymnocarpium appalachianum, a narrowly endemic fern. Understanding the species' distribution and potential relocation for conservation purposes is crucial. Ecological niche modeling was used to project the future distribution of G. appalachianum and suggests the importance of human-mediated population relocation to cooler areas.
