Summary: Conformational variability and heterogeneity play vital roles in determining the function of biological macromolecules. Experimental access to this information is limited by the lack of observable parameters compared to the potentially infinite number of available conformational states. Computational methods, such as reweighting the initial conformational ensemble, have been proposed to address this challenge.

Summary: The geometry of a ballasted railway deteriorates over time due to plastic settlement of the track-bed, which is difficult to predict accurately. Current empirical equations do not fully reflect the behavior of soil subgrades in cyclic loading, leading to the development of a semi-analytical approach to calculate plastic settlements more effectively. This new model is able to reproduce observed aspects of railway track settlement based on known behavior of soils and ballast in cyclic loading.

Summary: This study used the maximum entropy model to analyze the ecological suitability of Panax notoginseng under current and future climates, and evaluated the uniformity between quality and ecology by collecting multi-source chemical information of samples. The results showed that the suitable habitat of P. notoginseng was mainly in southwest China, and future climate change would severely impact the high suitable habitat. Additionally, different environmental factors had different effects on the accumulation of chemical components in P. notoginseng samples.

Summary: This study uses distribution information and surface observation data to analyze the ecological suitability of lemon planting in Sichuan Province. By considering climate, soil, and terrain factors, the study establishes a model to understand the relationship between lemon planting and its potential influencing factors. The results show highly suitable regions for lemon planting in Guang'an City, Nanchong City, Suining City, Ziyang City, Neijiang City and Zigong City, as well as some scattered regions in the Sichuan Basin. The study also identifies moderately suitable and slightly suitable regions, as well as unsuitable regions, providing valuable information for planning lemon planting in Sichuan Province.

Summary: The study on spatial patterns of moss phylogenetic assembly reveals that phylogenetic diversity is more robust than species richness, while global phylogenetic endemism is low. Future efforts for moss species collection, sequencing, and databasing should focus on the tropics, particularly Africa and Southeast Asia.

Summary: Globally, both climatic and anthropogenic factors are leading to a catastrophic decline of coral reef ecosystems. The study on Lakshadweep-Maldives-Chagos archipelago reveals the vulnerability of coral reefs in remote tropical islands. Habitat modeling using MaxEnt model shows outstanding predictive performance for Acropora muricata and Porites lutea, with bathymetry being the most contributing variable for coral distribution.

Summary: This study derived the vertical distribution of streamwise velocity in wide-open channels by maximizing Tsallis entropy, leading to a highly nonlinear differential equation for velocity which was then transformed and analytically solved. The derived velocity profile was validated and found to perform better than existing velocity profiles based on other entropies. This methodology can also be applied to other open channel flow problems.

Summary: The origin of flowering plants has been a transformative event in the history of the Earth, but the age of the group remains uncertain. Recent studies have provided conflicting estimates for the crown-group age of angiosperms. This study clarifies and distinguishes the different ages of angiosperms and argues that fossil-calibrated molecular dating estimates are mainly influenced by prior distribution. Future discoveries and novel analyses are needed for more definitive answers.

Summary: Mexican beech, an endangered tree species, inhabits fragmented cloud forests in eastern Mexico. Climate change has led to a significant decline in its distribution, with a projected further decrease in the next 50 years. However, some areas, such as Hidalgo, Veracruz, and Puebla, might serve as ecological refuges for Mexican beech due to their suitable habitat conditions.

Summary: The historical relationships of nine areas of endemism in the tropical montane cloud forests were analyzed using a temporal cladistic biogeographical approach. Geographic barriers and climatic fluctuations influenced the fragmentation and distribution of the TMCFs over time. The results highlight the importance of geological events during the Miocene-Pliocene and climatic fluctuations during the Pleistocene in shaping the current distribution of TMCFs.

Summary: Mexican Neotropical Symplocos species possess different wood anatomical adaptations to different climates and can be used to study the impact of drought on rare and endemic tree species. Neotropical montane oak forests are threatened by climate change, including drought and reduced fog and drizzle periods. This study used dendroecological and wood anatomical tools to assess the effect of historical drought events on annual growth and vessel anatomical traits in two rare relict-endemic species, Symplocos coccinea and S. speciosa. The findings suggest that high xylem plasticity allows these trees to adjust to drought quickly, highlighting the importance of diffuse-porous wood in adapting to climate variations.

Summary: This study investigated the phylogeographic structure of Crescentia alata and its relationship with past climatic changes, as well as the genetic diversity levels of homegarden populations and their association with human management. The results revealed a latitudinal pattern of phylogeographic structure with geographical barriers in the northern Pacific Ocean and the Tehuantepec Isthmus. Homegarden populations shared chloroplast haplotypes with wild populations, indicating that human management has not modified the natural phylogeographic structure of C. alata.

Summary: This study examines the distribution, knowledge, and conservation status of twenty-six tree species in the Mexican cloud forests, with many species threatened and listed on international and national red lists. Distribution maps were generated based on various sources of information, and the representativeness of these species in the current Mexican System of Natural Protected Areas was evaluated. The study highlights the need for specific conservation policies for most of the species due to problems affecting their populations and habitats.

Summary: This study investigates the phylogeography of Quercus mexicana and finds high genetic diversity and low genetic structure in populations. Ecological niche models suggest historical fluctuations in the distribution of Q. mexicana. Historical range changes, gene flow, and physical barriers have played an important role in shaping the phylogeographic structure of Q. mexicana.

Summary: Genomic data and machine learning approaches are being used to identify adaptive genetic variation and assess species vulnerability to climate change. The estimation of genetic offsets, which measure future maladaptation of populations due to climate change, is sensitive to the number of sampled populations, especially when genetic structure is high. The number of individuals sampled per population has minimal effects on the estimation of genetic offsets, and multiple future climate scenarios should be considered to evaluate estimation sensitivity.

Summary: Digital accessible biodiversity knowledge is important for botanical research and conservation efforts. However, there are shortcomings in the data coverage, species diversity characterization, and phylogenetic representation across Mesoamerica. These issues compromise the quality of available occurrence data and hinder research on spatial phylogenetics and species dynamics. Efforts in data digitization, botanical exploration, sequencing, and biodiversity monitoring are needed to rejuvenate knowledge on the geographic distribution of vascular plants in the region.
