The degree of genetic diversity of the steppe field mouse was estimated on the basis of the mtDNA control region variability data. Polymorphism of this mtDNA marker in S. witherbyi was more pronounced than previously assumed. The steppe field mouse population from the northern shore of Lake Manych-Gudilo includes several mitochondrial lines, which may be due to the existence of several migration flows to this area from Southwest Asia.

Introduction: Belowground bud banks (or bud-bearing organs) underlie grassland regeneration and community succession following ecosystem perturbations. Disturbances of nitrogen (N) enrichment, overgrazing, wildfire, and drought substantially affect grassland ecosystem succession and aboveground productivity.

Methods: To understand the magnitude and direction of the disturbances on the belowground bud banks, we conducted a meta-analysis on 46 peer-reviewed studies published from 1980 to 2023.

A central goal of ecosystem restoration is to promote diverse, native-dominated plant communities. However, restoration outcomes can be highly variable. One cause of this variation may be the decisions made during the seed mix design process, such as choosing the number of species to include (sown diversity) or the number of locations each species should be sourced from (source diversity, manipulated to affect genetic diversity).

Background: To align with climate goals, greenhouse gas (GHG) emissions from agriculture must be reduced significantly. Cultivated peatlands are an important source of such emissions. One proposed measure is to convert arable fields on peatlands to grassland, as the Intergovernmental Panel on Climate Change (IPCC) default emission factors (EF) for organic soils are lower from grasslands.

Influence of drought stress on phosphorus dynamics and maize growth in tropical ecosystems.

BMC Plant Biol

January 2025

Center for Eco-Environment Restoration of Hainan Province, School of Ecology, Hainan University, Haikou, 570228, China.

Drought has a significant impact on ecosystem functions, especially on the biogeochemical cycling of phosphorus (P), which is a crucial nutrient for plant growth and productivity. Despite its importance, the effects of different drought scenarios on soil P cycling and availability remain poorly understood in previous studies. This study simulated drought conditions in tropical soils using maize as a test crop under varying field capacity (FC) levels (100%, 80%, 60%, 40%, and 20%) over a 60-day pot experiment.

Thermal ecology of the Mexican Garter Snake (): temporal and spatial variations.

PeerJ

January 2025

Facultad de Ciencias, Universidad Autónoma del Estado de México, Toluca, Estado de México, Mexico.

Heterogeneous environments provide different daily and seasonal thermal conditions for snakes, resulting in temporal and spatial variations in body temperature (Tb). This study analyzes the Tb of in the forest and grassland of a Mexican locality through daily and seasonal profiling. The patterns were obtained from seminatural enclosures in the field with a point sampling strategy to analyze temporal and spatial variations in Tb.
