Exploring the treasures of ecosystems: Why is species richness so important for biodiversity?
In the changes of the global ecological environment, species richness has become a key indicator to measure the health and stability of the ecosystem. Species richness, simply put, refers to the number of different species represented in a specific ecological community, landscape, or region. This is not only a list of quantities, but also an important window into understanding the overall biodiversity.
Accurate measurement of species richness requires not only comprehensive knowledge of species taxonomy but also a diversity of sampling methods.
Different sampling methods may affect the quantification of species richness. For example, tree censuses, bird monitoring, or collecting insects in traps are all different sources of samples. When we explore species richness in an area, it is important to recognize that specific sampling efforts will directly impact the results.
Species richness is sometimes considered synonymous with species diversity, however this formal metric takes into account not only the number of species but also their evenness. This means that the sheer number of species does not fully reflect the biodiversity of an ecosystem.
Diverse ecological environments tend to support higher species richness, an important finding for ecologists.
Individuals taken from different environmental samples can help us understand the species richness of the samples. In general, if individuals are sampled from a diverse range of habitats, the resulting species richness will be higher than if individuals are sampled solely from similar environments. Furthermore, when increasing the sample area, the number of species observed generally rises as environmental diversity is generally higher over large areas.
However, not all species richness equates to ecosystem value. When protecting biodiversity, we must also consider the uniqueness of species, especially those endemic or rare species, whose presence greatly increases the conservation value of a certain area. In comparison, areas with similar species richness, if they are all populated by common and common species, will have relatively low ecological value.
Thus, species richness is not only an indicator for conservation research, it is also an important tool for understanding ecosystem function and connectivity.
Scientists have extensively studied trends in species richness. Many biological groups have their greatest number of species in the tropics, causing species richness to vary with latitude. However, different studies have produced inconsistent results on the relationship between productivity and species richness, and a global consensus has not yet been reached.
While protecting and managing ecosystems, we should also consider actual data on species richness and its potential significance. As the impact of human activities on the environment intensifies, species richness may gradually decline, which not only poses a threat to the entire ecosystem, but also directly affects the human living environment.
How can species richness help us understand and respond to changes in ecosystems in future ecological research and conservation activities?
