AI Article Synopsis
- Climate heavily influences where species can thrive geographically, making it crucial to understand how climate change affects this potential distribution for resource use and ecological sustainability.
- Betula platyphylla Suk., a significant tree species in East Asia, shows current suitable habitats mainly in northeastern to southwestern China, with key environmental factors like temperature and precipitation shaping its distribution.
- Future predictions indicate that suitable areas for Betula platyphylla may expand due to global warming, even as current populations face threats from diseases and environmental damage.
Article Abstract
Climate is a dominant factor affecting the potential geographical distribution of species. Understanding the impact of climate change on the potential geographic distribution of species, which is of great significance to the exploitation, utilization, and protection of resources, as well as ecologically sustainable development. Betula platyphylla Suk. is one of the most widely distributed temperate deciduous tree species in East Asia and has important economic and ecological value. Based on 231 species distribution data points of Betula platyphylla Suk. in China and 37 bioclimatic, soil, and topography variables (with correlation coefficients < 0.75), the potential geographical distribution pattern of Betula platyphylla Suk. under Representative Concentration Pathway (RCP) climate change scenarios at present and in the 2050s and 2070s was predicted using the MaxEnt model. We analyzed the main environmental variables affecting the distribution and change of suitable areas and compared the scope and change of suitable areas under different climate scenarios. This study found: (1) At present, the main suitable area for Betula platyphylla Suk. extends from northeastern to southwestern China, with the periphery area showing fragmented distribution. (2) Annual precipitation, precipitation of the warmest quarter, mean temperature of the warmest quarter, annual mean temperature, and precipitation of the driest month are the dominant environmental variables that affect the potential geographical distribution of Betula platyphylla Suk. (3) The suitable area for Betula platyphylla Suk. is expected to expand under global warming scenarios. In recent years, due to the impact of diseases and insect infestation, and environmental damage, the natural Betula platyphylla Suk. forest in China has gradually narrowed. This study accurately predicted the potential geographical distribution of Betula platyphylla Suk. under current and future climate change scenarios, which can provide the scientific basis for the cultivation, management, and sustainable utilization of Betula platyphylla Suk. resources.

Heat stress transcription factors (HSFs) play a critical role in orchestrating cellular responses to elevated temperatures and various stress conditions. While extensively studied in model plants, the gene family in remains unexplored, despite the availability of its sequenced genome. In this study, we employed bioinformatics approaches to identify 21 genes within the genome, revealing their uneven distribution across chromosomes.

Saline-alkaline salinity is recognized as one of the most severe abiotic stress factors, limiting plant growth and resulting in significant yield losses. MYB transcription factors (TFs) are crucial for plant tolerance to abiotic stress. However, the roles and regulatory mechanism of MYB TFs underlying saline-alkaline stress tolerance has not yet been investigated in Betula platyphylla.

We elucidated the changes of soil microbial biomass and community structure in soil profiles under four typical land use types (farmland, grassland, secondary forest and plantation)and across five soil layers (0-10, 10-20, 20-30, 30-40, 40-50 cm) in the northern mountainous region of Hebei Province. We measured soil microbial biomass by phospholipid fatty acid (PLFA) method, and investigated the effects of land use and soil depth on soil microbial biomass and community structure by variance analysis, correlation analysis and redundancy analysis. The results showed that soil water content, bulk density, and organic carbon content of farmland differed significantly from other land use types.
