Worldwide evidence of a unimodal relationship between productivity and plant species richness
TLDR
A large, standardized, and geographically diverse sample of grasslands from six continents is used to confirm the validity and generality of the humped-back model of plant species diversity and pave the way for a more mechanistic understanding of the factors controlling species diversity.
Investigating the altitude effect on the quantity and quality of the essential oil in Tanacetum polycephalum Sch.-Bip. polycephalum in the Baladeh region of Nour, Iran.
TLDR
The results showed that as the altitude increases, the essential oil compositions revealed the greater quantity and percentage in the aerial parts of T. polycephalum.
Capability Investigation of Carbon Sequestration in Two Species (Artemisia sieberi Besser and Stipa barbata Desf.) Under Different Treatments of Vegetation Management (Saveh, Iran)
The rangelands, as one of the largest dynamic biomes in the world, have very capabilities. Regulation of greenhouse gases in the Earth's atmosphere, particularly carbon dioxide as the main greenhouse
Not a melting pot: Plant species aggregate in their non‐native range
TLDR
The strong differences between the native (home) and non‐native (away) range in species co‐occurrence patterns are evidence that the way in which species associate with resident communities in their non-native range is not species dependent, but is instead a property of being away from their native range.
THE STUDY OF DIVERSITY INDICES OF PLANTS SPECIES USING SHE METHOD (CASE STUDY: JAVAHERDEH RANGELANDS, RAMSAR, IRAN)
Recent attitude of vegetation assessors is using of new ecologic approaches to evaluate and analyse the complex rangeland ecosystems. Plant diversity is the most important indices to assess the
COMPARISON OF MEASUREMENT INDICES OF DIVERSITY, RICHNESS, DOMINANCE, AND EVENNESS IN RANGELAND ECOSYSTEM (CASE STUDY: JVAHERDEH-RAMESAR)
The diversity and richness of species are of important components to evaluate the health of ecologic system of rangelands. This research was conducted to investigate the biodiversity in riparian and
The effects of altitude on chemical compositions and function of essential oils in Stachys lavandulifolia Vahl. (Iran)
TLDR
1600 m asl was the most desirable altitude to grow species to achieve the optimal quality and quantity of the essential oils in Stachys lavandulifolia.
EFFECTS OF HARVESTER ANTS’ NEST ACTIVITY (MESSOR SPP.) ON STRUCTURE AND FUNCTION OF PLANT COMMUNITY IN A STEPPE RANGELAND (CASE STUDY: ROODSHOOR, SAVEH, IRAN)
TLDR
The ant activities in the active and inactive nests can bring out micro sites with different plant associations so that regarding high density and quantity of the ant nests in all the area, it can decrease the key plants and change their functions, which will debilitate the stability and function of this rangeland ecosystem.
Study of chemical composition and antibacterial effects of essential oils of Stachys lavandulifolia Vahl., Salvia verticillata L., and Tanacetum polycephalum Schultz-Bip. on some microbial lineages
TLDR
The essence of Stachys lavandulifolia and Salvia verticillata has the most antibacterial effects upon Escherichia coli and the least one on Staphylococcus aureus, and it is suggested to use the essences in the food industries as natural additive and healthy mat.
