“…We found that mean species richness is less on the southern slope compared to the northern slope (Appendix S1: Table S1). Previous studies have also shown a negative relationship between species richness and soil pH (Diamond andSmeins 1985, Palpurina et al 2017). Previous studies have also shown a negative relationship between species richness and soil pH (Diamond andSmeins 1985, Palpurina et al 2017).…”

A positive relationship between plant species richness and biomass has often documented in temperate grassland systems but is still largely lacking in the Himalayan region. Considering altitude and soil properties as major factors influencing species richness and biomass in the Himalayan grasslands, we tested the hypothesis that peak aboveground biomass and species richness increase with higher levels of soil nutrients and decrease with altitude. Our study was conducted in the grasslands of Tibet, China, and Manang District, Nepal, which represent, respectively, the northern and southern slopes of the central Himalayan grasslands. During the growing seasons, we measured vegetation aboveground biomass and soil properties along an altitudinal gradient on the northern slope in 2011 and 2012, and on the grasslands of the southern slope in 2017. Data were analyzed with a Spearman correlation analysis, classification and regression tree model, and the structural equation modeling (SEM) to identify the key factors determining aboveground biomass and species richness. The results demonstrated that aboveground biomass and species richness on the southern slope were significantly greater at the lowest altitude zone compared to middle and higher zones, whereas on the northern slope, aboveground biomass and species richness were not significantly different at three altitudinal zones. There was a significant positive correlation between aboveground biomass and species richness on both northern and southern slopes. However, the slope was found higher in grasslands of southern slope compared to the grasslands of northern slope. Classification and regression tree analysis and SEM indicated that altitude is most closely associated with large-scale variations in aboveground biomass and species richness. The Spearman correlation analysis revealed that altitude and soil pH were negatively related to aboveground biomass in these grasslands. This study demonstrates that on northern and southern slopes of the Himalayan Range, a positive relation between plant species richness and biomass is determined more by altitude than soil nutrients.

We analyzed the geographic distribution and climatic controls of the distribution of plant functional types (PFT) in temperate grasslands and shrublands of North America. It has been widely accepted that temperature is the principal control on the distribution of C3 and C4 species. Our results show that precipitation and its seasonal distribution are also important. C4 grass distribution was positively related to three climatic variables: mean annual precipitation, mean annual temperature, and the proportion of the precipitation falling in summer. These variables accounted for 66% of the total variability of this functional type. C3 grass abundance decreased with mean annual temperature and increased with the proportion of the precipitation falling during winter (r2 = 0.37). Sixtytwo percent of the variability in the relative abundance of shrubs was explained by mean annual precipitation and the proportion of winter precipitation.Latitude and longitude explained a substantial portion of the variability of the distribution of the relative abundance of shrubs, C3 grasses, and C4 grasses (53, 46, and 61%, respectively). Along a given longitude, C3 grasses increased with latitude. As one moves westward, C4 grasses are replaced by shrubs. The relative abundance of C4 grasses reached a maximum at southern latitudes and eastern longitudes. Succulents showed a marginal decreasing trend with latitude. No relationship with geographic variables was detected for forbs.

1992. Changes in species biomass in thc Coastal Prairic of Texas when light and nutrients are altered. Can. J. Bot. 70: 1777-1783. A 2 X 2 factorial experiment using light and nutrients as factors was carried out over 2 % years in a remnant, native Coastal Prairie of Texas. Light level, nutrient level, and date of sampling all had significant influences on total biomass, but changes were subtle, suggesting additional limiting factors. More obvious were changes in biomass of individual species, especially the dominant C, grass species. Schizachyriutn scopnrilirn (Michx.) Nash (little bluestem), Pnspal~irrr plicnt~ilum Michx. (brownseed paspalum), and Sorghastrurtr lzutans (L.) Nash (Indian grass), three C, grasses, maintained their biomass at low nutrient levels throughout the study. Sorghastrurn trrirans responded to higher nutrient levels with increased biomass, whereas the biomass of S. scopariurn and P. plicatrilurn decreased. Results suggest that remnant grassland communities dominated by P. plicaturn and S. scopariur~r are relatively stable conlnlunities maintained by yearly mowing, which removes biomass and nutrients. With the accunlulation of litter, surface light levels would decrease, soil nutrients would increase, and S. nutans biomass would increase at the expense of P. plicatulurn and S. scopariurn.

Les auteurs ont conduit une expkrience factorielle 2 x 2 impliquant les facteurs lumikre et nutriment; cette expCrience a d u d deux ans et demi dans un vestige de la prairie c6tikre aborigttne du Texas.L'intensitC lumineuse, la teneur en nutriments et la date d'Cchantillonage montrent toutes des influences significatives sur la biomasse totale, mais il y a des modifications subtiles qui suggkrent l'existence d'autres facteurs limitants. Ce qui est le plus remarquable, ce sont les changements de biomasse d'espttces individuelles, surtout les espkces herbacCes dominantes en C,. Trois herbacees en C, ont maintenu une biomasse constante aux niveaux infkrieurs en nutriments : ce sont Sclliznchyririm scoparium (Michx.) Nash, Pnspalrirn plicatulrttn Michx. et Sorghnsrrritn nutans (L.) Nash. Le S. trutans reagit 5 des teneurs plus ClevCes en nutriments par une augmentation de biomasse, alors que les biomasses du S. scoparium et du P. plicatrilurn diminuent. Les rksultats suggkrent que les communautCes d'herbacies vestigiales dominCes par les P. plicntrilri~~z et S. scopnrirtm sont des communautCs relativement stables, maintenues par une tonte annuelle, qui Climine la biomasse et les nutriments. Avec une accumulation de litikre, les niveaux de lumikre en surface diminueraient, les nutriments augmenteraient dans le sol et la biomasse du S. nutans augmenterait aux dCpens de celles des P. plicatulrttn et S. scopnrium.
