Summary: Habitat factors such as topography and soil nutrients affect understory plant diversity patterns on a small scale, with regions of medium altitude, gentle slope, and high organic matter content being more likely to have abundant diversity. Topographic factors have a dominant effect on diversity distribution, while soil nutrient factors also play a significant role. Promoting soil biochemical cycles can effectively increase understory plant diversity.

Summary: Predicting the effects of climatic changes on species requires understanding the factors shaping the spatial genetic composition. In this study, we found that the colonization history is the most important driver of the genetic pattern of Oriental beech, and local climate also influences the genetic composition. The loss of genetic resources due to projected habitat loss may increase the vulnerability of the Azerbaijan and Hyrcanian populations to environmental change, which could ultimately affect the species' adaptation and the stability of forest ecosystems in the Caucasus ecoregion.

Summary: Large apes in Africa are losing suitable habitats due to human activities, leading to potential threats to their reproduction and survival. This study focuses on assessing the habitat suitability of the Nigeria-Cameroon chimpanzee in the Kom-Wum Forest Reserve in North-West Cameroon. Using a common species distribution model, the study finds that only 9% of the study area is suitable for chimpanzees, with a significant proportion of suitable habitats located outside the forest reserve. Factors such as elevation, forest density, and proximity to villages and primary forests are found to be important predictors of habitat suitability.

Summary: The study found that the nitrogen uptake patterns of understory trees vary between different overstory trees, possibly due to differences in soil mycorrhizal community and nitrogen availability. Understory trees beneath non-ECM overstory trees primarily absorbed nitrogen as nitrate, while those beneath ECM overstory trees relied on mycorrhizal fungi for nitrogen acquisition. Leaf nitrogen concentrations were lower in understory trees beneath ECM compared to non-ECM overstory trees.

Summary: Fine roots are the most active and functional component of root systems, playing a significant role in acquiring soil resources. This study analyzed the influence of soil and leaf traits on fine root growth in plantations of black locust and Chinese pine with different density classes. Fine root biomass increased with stand density, with high fine root biomass achieved through increases in fine root production and turnover rate in high-density black locust plantations and through increased fine root production in pine plantations. Fine root production and turnover rate were closely related to soil volumetric water content, while fine root biomass, especially necromass, was linked to soil nutrient status. Leaf area index was closely linked to fine root dynamics in black locust plantations but not in pine plantations.
