This study aims to explore the differential patterns of selective constraints in different niches, in order to reveal the mechanism of niche differentiation and the role of niches in biological communities. By understanding the concept of niche and the basic concepts of selective constraints, one can grasp the differential patterns of selective constraints in different niches. Through case studies and the impact of niche characteristics, the changes in selective constraints under different environmental conditions were elucidated. In addition, the impact of selective constraints on niche differentiation and evolution was also explored, emphasizing the importance of future research. This study aims to deepen the understanding of the diversity and niche differentiation of selective constraints in different niches, and provide scientific basis for biodiversity conservation and ecosystem management. Keywords Niche; Selective constraints; Niche differentiation; Niche characteristics; Biodiversity Selective constraint, as one of the key concepts in the fields of biology and ecology, represents one of the key impacts faced by the evolution of biological populations. It involves environmental constraints on individual survival and reproduction, forming the foundation of biodiversity and ecosystems (Chang et al., 2020). Selective constraints refer to the different effects of natural selection on specific traits or genotypes, which reflect the differences in adaptability of organisms to environmental conditions (Shtolz and Mishmar, 2019). In the long river of evolution, selective constraints are a key driving factor for species morphological diversity and niche differentiation. By delving into the mechanisms and effects of selective constraints, we can better understand diversity and interaction in the biological world. In nature, biological populations are distributed in different ecological niches, which provide them with unique resources and environmental conditions. However, organisms in different ecological niches face different selective constraints. These differences may be caused by various factors such as resource availability, competitive pressure, and predator pressure. Understanding the differential patterns of selective constraints in different niches is crucial for revealing the adaptive evolution and niche differentiation of organisms (Yan et al., 2021). The purpose of this study is to explore in depth the differential patterns of selective constraints in different ecological niches, in order to reveal the basis for the adaptive evolution strategies and interactions of organisms in different ecological niches. This study will introduce the concept of niche, delve into the definition and types of selective constraints, discuss the differential patterns of selective constraints in different niches, and use case studies and the impact of niche characteristics as support to elucidate how selective constraints exhibit changes under different environmental conditions. Starting from the impact of selective constraints on niche differentiation and evolution, as well as how they drive species diversity in ecosystems, discuss the significance of these results in the fields of ecology and evolutionary biology, as well as potential contributions to future research. By delving into the differential patterns of selective constraints in different niches, the aim is to provide scientific basis for the study of biodiversity and niche differentiation.
