Published: Jan. 23, 2024

Aim East Asian subtropical evergreen broad-leaved forests (EBLFs) are composed of western and eastern subregions with different topographical environmental conditions. The distribution shifts over time plants in the two predicted to be different, but difference has seldom been investigated. Methods Potential distributions 53 Magnoliaceae species (22 31 subregion) during last glacial maximum (LGM), present, 2070s were using MaxEnt based on 58 variables. changes range size centroid analyzed. Species-level potential habitats overlaid uncover diversity distribution, discover long-term refugia. Results At significantly larger than those shown by occurrence points. During LGM, 20/22 subregion experienced increases through downwards southward migrations, while decreases (27/31 species) accompanied northward eastward migrations. In future, declines will both found; northwestward exist most (20/22 subregion, northwest- northeastward occur subregion. hotspots a slight shift past upwards mountain region future subregion; shrinks occurred China all regions future. Long-term refugia-preserving was found mountains across entire EBLFs region. Main conclusions Significant differences from present similar revealed subregions. Species no significant could preserved mountainous throughout EBLFs.

Potential Impacts of Climate Change on the Spatial Distribution Pattern of Naked Oats in China

Agronomy, Journal Year: 2025, Volume and Issue: 15(2), P. 362 - 362

Published: Jan. 30, 2025

Naked oats, a significant minor cereal crop in China popular for its nutrient richness, have experienced surge production recent years, fueled by the escalating demand wholesome healthy food. However, dispersed and disorganized cultivation plan of naked oats poses constraint on industrial progression. Considering dual influence cultivation, management techniques, global climate change this study explores potential impacts spatial distribution yield crop. Leveraging CMIP6 models (BCC-CSM2-MR, CanESM5, CNRM-ESM2-1) an optimized MaxEnt model (RM = 0.5, FC LQ), we simulated climate-suitable zones from 1990 to 2020 forecasted alterations under various emission scenarios 2021 2100. The achieved average accuracy test with high value (AUC 0.945) predicting suitable areas; precipitation seasonality (Coefficient Variation) (bio15, 21.70%) topsoil pH (H2O) (T_PH_H2O, 21.00%) as key factors, both soil properties greater influence. Simulation results showed that climatically area increased all scenarios, largest increase optimal growing ssp126 2030s. was 3.93% 0.77 × 106 km2. also compared data main producing counties Shanxi Province 2022 statistical purposes, found 39 were climatic suitability remarkably zones. agreement rate between planting areas 97.44%. Further, expanded westward, increasing intensity. This reveals current pattern providing scientific rationale addressing through multi-scenario predictions. Our findings implications optimizing layout identifying zones, supporting sustainable agricultural development strategies China.

Rules of Plant Species Ranges: Applications for Conservation Strategies

Frontiers in Ecology and Evolution, Journal Year: 2021, Volume and Issue: 9

Earth is changing rapidly and so are many plant species’ ranges. Here, we synthesize eco-evolutionary patterns found in range studies how knowledge of species ranges can inform our understanding conservation the face global change. We discuss whether general biogeographic “rules” reliable they be used to develop adaptive strategies native across their Rules considered include (1) factors that set limits promote shifts; (2) impact biotic interactions on limits; (3) abundance properties ranges; (4) gene flow implications for genetic rescue, (5) relationship between size risk. conclude by summarizing evaluating potential rules future management decisions. also outline areas research better understand capacity plants under environmental change govern advise conservationists extend work specifically consider peripheral novel populations, with a particular emphasis small Finally, call effort identify, synthesize, analyze prevailing or ecology help speed efforts.

Medicinal plants used for cutaneous wound healing in Uganda; ethnomedicinal reports and pharmacological evidences

Heliyon, Journal Year: 2024, Volume and Issue: 10(9), P. e29717 - e29717

Published: April 16, 2024

Wounds have become a major health challenge worldwide, presenting marked humanistic and economic burdens such as disabilities death. Annually, approximately 14 million people suffer from wounds worldwide 80 % of these occur in developing countries like Uganda. In Uganda, besides many cases daily wound occurrences, 10 surgical procedures septic consequently lead to increased morbidity mortality. Accordingly, several ethnomedicinal studies identified plants used for treatment different parts Uganda the healing activities some been reported. However, at present, information remain largely separated without an all-inclusive repository containing pharmacological thus retarding appropriate evaluation. Therefore, this review focused on extensively exploring treating cutaneous along with associated their globally reported potential.

Pandanus plastomes decoded: When climate mirrors morphology and phylogenetic relationships

American Journal of Botany, Journal Year: 2025, Volume and Issue: unknown

Abstract Premise Pandanus Parkinson (Pandanaceae) is a large genus of paleotropical tree‐like monocots. Previous studies using small DNA regions questioned the monophyly seven subgenera, but low phylogenetic branch support hindered further investigations. We aimed to (1) test subgeneric monophyly, (2) identify clade morphological synapomorphies, (3) investigate correlations between leaf anatomy water storage tissue and climatic differentiation across clades, (4) construct hypotheses on genus' spatiotemporal history. Methods sequenced 50 species genome skimming reconstructed plastomes with MITObim. inferred partitioned RAxML trees Shimodaira–Hasegawa tests. dated BEAST tree used for ancestral state reconstructions traits. Phylogenetic clades were compare (Bioclim) soil (UNESCO Digital Soil Map) conditions random forests. correlated present morphology niche past climate events. Results Our analyses revealed two four subclades. Only subgenus Coronata was monophyletic. Staminate synapomorphies identified three Hypertrophied hyperplasic water‐storage synapomorphy II, correlating more seasonal temperature precipitation regimes well‐draining soil. Clades differentiated during advent Southeast Asian monsoon in early Miocene, whereas subclades Miocene Thermal Maximum. Conclusions classification needs be revised. key trait evolution, possibly explaining biogeographic patterns because it maintaining photosynthesis periods hydric stress.

In response to climate warming, alpine plants are migrating higher elevations and latitudes track suitable habitats. mountainous systems, the contraction of land area toward mountaintops is causing plant habitats shrink as migrate upwards. The Tibetan Plateau (TP) its adjacent Himalaya-Hengduan Mountains (HHMs) constitute world's highest flora, known "Third Pole" To predict responses change in Third Pole, we utilized four endemic Lamiaceae herbs an Ecological Niche Modeling (ENM) based on comprehensive data comprising 740 occurrence records 26 environmental variables using Biomod2. primary results revealed that climate-related factors, particularly temperature variability, shape distribution patterns study species drive them upward northward future. heterogeneous topography HHM TP leads distinct dynamics. can provide substantial new potential areas mitigate habitat loss under warming. Meanwhile, stable high-elevation regions within serve refugia ensure survival change.
