An Exploration of Plant Biomass–Species Richness Relationships in Three Subalpine Grasslands on the Qinghai–Tibetan Plateau
Aims
Multiple studies have addressed the relationship between plant biomass and species richness, often reporting a hump-shaped curve. However, such research in natural grassland was mostly conducted in temperate, arid and semiarid areas, with few studies focused on subalpine regions. Moreover, in most cases, plant community biomass was the main variable of interest, with few studies considering also plant individual biomass, calculated by dividing plant community biomass by plant abundance.
Location
To explore the relationship between plant biomass and species richness in subalpine regions, a field survey was conducted in three locations with fenced subalpine grasslands on the Qinghai–Tibetan Plateau in China in 2020 and 2023.
Methods
Plant aboveground biomass and species richness were recorded along four transects in each location. Analyses were performed using both plant community biomass and plant individual biomass to test whether using a different biomass measure affected the plant biomass–species richness relationship.
Results
Location and Year × Location significantly affected species richness, plant community biomass and plant individual biomass. Curve estimations demonstrated a positive nonlinear relationship between plant community biomass and species richness and a negative nonlinear relationship between plant individual biomass and species richness. These patterns were modified by the locations of the three grasslands. Competition can explain some of the different patterns between plant community biomass–species richness relationship and plant individual biomass–species richness relationship.
Conclusions
In general, the choice of biomass approach affected the relationship between plant biomass and species richness in subalpine grasslands, which indicates that plant abundance impacts plant biomass–species richness relationship. Future research should consider further modulators and drivers when exploring the plant biomass–species richness relationship in grasslands in a climate change context.
期刊介绍：
The Journal of Vegetation Science publishes papers on all aspects of plant community ecology, with particular emphasis on papers that develop new concepts or methods, test theory, identify general patterns, or that are otherwise likely to interest a broad international readership. Papers may focus on any aspect of vegetation science, e.g. community structure (including community assembly and plant functional types), biodiversity (including species richness and composition), spatial patterns (including plant geography and landscape ecology), temporal changes (including demography, community dynamics and palaeoecology) and processes (including ecophysiology), provided the focus is on increasing our understanding of plant communities. The Journal publishes papers on the ecology of a single species only if it plays a key role in structuring plant communities. Papers that apply ecological concepts, theories and methods to the vegetation management, conservation and restoration, and papers on vegetation survey should be directed to our associate journal, Applied Vegetation Science journal.
