Summary: A novel Genetic Algorithm model was developed to design the most optimised Tidal Range Schemes for electricity generation, with a new scheme proposed for the Bristol Channel, UK. The comparison showed that the Genetic Algorithm model was capable of achieving similar outcomes to traditional Grid Search methods, while reducing computational time significantly.

Summary: Plant populations at the leading edge of the species' native range often exhibit genetic structure as a result of genetic drift and adaptation. This study examines the genetic structure of northern red oak populations, finding pronounced genetic differentiation between island and mainland/peninsular populations. Additionally, strong fine-scale spatial genetic structure is observed in all locations, with more pronounced structure in colder and drier regions. The study suggests that the harsh environment of leading edge populations influences population density and seed shadow overlapping, leading to the observed patterns of genetic structure.

Summary: In the context of forecasted climate change scenarios, the growth of forest tree species at their distribution margin is crucial to adapt current forest management strategies. This study analyzed the growth of beech populations in the Republic of Moldova and found that the marginal populations had higher growth rates compared to core distribution sites. The study also revealed a significant response of beech growth to climatic variables, particularly vapor pressure deficit (VPD), indicating that water deficit is a limiting factor for beech growth in the region.

Summary: In the last decade, coniferous stands outside their natural range in Romania have experienced declines in both their health and growth, and these forests are becoming even more threatened due to global climate trends. A study in the Romanian Carpathians examined the relationship between tree growth and defoliation as an indicator of tree health. The results showed an increase in defoliation and a negative trend in radial growth, driven by defoliation.

Summary: For many species, local abundance and regional occupancy are highest near the center of their geographic distributions, which supports the central-marginal hypothesis. This hypothesis suggests that niche suitability declines as distance from the geographic center increases, resulting in reduced density and increased patchiness in edge populations. Using genomic data from Australian scincid lizards, we found that a majority of the taxa tested showed patterns of genetic variation consistent with the central-marginal hypothesis. Additionally, taxa with evidence of range expansion were less likely to follow the predictions of the hypothesis.

Summary: The response of European beech to climate warming and water shortage was investigated in this study. The findings suggest that precipitation plays a significant role in cambial activity and hydraulic control. Summer precipitation affects ring width, while water availability during vessel expansion phase affects mean vessel area. The effect of chronology type on climatic response is stronger than geographical location or altitude.

Summary: The study reveals that precipitation plays a crucial role in controlling the secondary growth and xylem structure of European beech, with different effects on ring width and vessel size. Regional differences were significant but less important compared to the influence of chronology type, suggesting common climate constraints on beech's growth and anatomy along its dry edge.

Summary: In this study, the researchers investigated the demographic, physiological, and genetic changes in the intertidal gastropod Nerita yoldii, which has expanded its range by 200km over the Yangtze River Estuary. They found that the new marginal populations formed a distinct cluster, experienced a genetic bottleneck, and showed high levels of heterozygosity. The new marginal populations also exhibited divergent transcriptomic and physiological responses to heat stress, allowing them to occupy and survive in the new environment.

Summary: Understanding the stress distribution and failure characteristics around a U-shaped cavern is important for the stability analysis of rock structures. This study analyzed the stress distribution based on complex variable theory and conducted numerical simulations to study the failure process and energy evolution of a U-shaped cavern with different height-to-width ratios. The results show that the height-to-width ratio affects the stress concentration and failure process of the cave walls, vault, and floor. The direction of the maximum principal stress also influences the stability and failure characteristics of the cavern. Therefore, the design of the support system for U-shaped caverns should consider both the height-to-width ratio and the direction of the maximum principal stress.

Summary: This study presents the spatial distribution of genetic variability and diversity in B. patula populations using eight polymorphic SSR markers. Despite some genetic differences, the CI and DI populations have more similarities than differences. Analysis of the Molecular Variance showed that 9% of the diversity is between populations, 68% among individuals, and 23% within individuals.

Summary: The coralline algal genus Corallinapetra is monospecific and distinct from other families and orders within the Corallinophycidae. DNA analysis supports the establishment of a new family and order for Corallinapetra, and the reassignment of L. gabrielii to Corallinapetra. Additionally, comparison of molecular data confirms the placement of L. muelleri within the Hapalidiales.

Summary: The study identified genomic signatures of partial clonality in the deep water kelp species Laminaria rodriguezii and compared them with a closely related species Laminaria digitata. The findings showed distinct genetic distributions and different impacts of clonality and genetic drift on population diversity. These results provide insights into the genetic study of asexuality in natural populations and highlight potential applications of RAD-sequencing in investigating partial clonality in various non-model species.

Summary: A study on the evolution of life cycles in brown algae revealed that diploid growth evolves when sexual reproduction is preferred over asexual reproduction. The research also found that haploid sex determination is ancestral to diploid sex determination, and isogamous species in brown algae evolved from anisogamous ancestors, contrary to the commonly reported pattern of evolution from isogamy to anisogamy.

Summary: Marine ecosystems formed by kelp forests are at risk from global change and local disturbances, making it crucial to identify genetic diversity reservoirs and develop tools such as microsatellite markers. Research found a decrease in cross-amplification of markers between closely related species with increasing genetic distance, and proposed a rapid PCR identification method based on species-specific COI mitochondrial primers to distinguish between four kelp species.

Summary: Recent studies have contradicted the long-held belief that animal-mediated pollination is absent in the sea, particularly in seagrasses, sparking interest in investigating other marine phyla. This study discovers that biotic interactions can significantly increase the fertilization success of red algae through animal transport of spermatia, suggesting that animal-mediated fertilization may have evolved independently in terrestrial and marine environments and could have emerged in the sea before plants moved ashore.

Summary: This study aimed to test the local adaptation in giant kelp and found that there are variations in temperature tolerance among different regions and populations. However, high latitude populations are not always more heat resilient than low latitude populations. Additionally, the gametophytes of the giant kelp have a large range of temperature tolerance, indicating their resistance.

Summary: This study used SNP to assess the genetic structure of Gracilaria chilensis in Chile and found that the low genetic diversity may be associated with over-exploitation and colonization history. The Quaternary glacial cycles had important effects on the species in New Zealand.

Summary: The author examines the combat peculiarities of the 47th Infantry Regiment of the French Army during the First World War, showing the impact of environmental conditions on soldiers' intensity and efficiency in combat operations. Soldiers faced vulnerability to temperature changes, physical strain from marches, and health risks from polluted battlefields. The environment also influenced combat effectiveness and made operations more difficult during severe environmental changes.
