Effects of plant species richness on stand structure and productivity
Aims Aboveground biomass production commonly increases with species richness in plant biodiversity experiments. Little is known about the direct mechanisms that cause this result. We tested if by occupying different heights and depths above and below ground, and by optimizing the vertical distribution of leaf nitrogen, species in mixtures can contribute to increased resource uptake and, thus, i...
متن کاملWater relations and photosynthetic capacity of two species of Calotropis in a tropical semi-arid ecosystem.
BACKGROUND AND AIMS Calotropis procera and Calotropis gigantea, originally from warm parts of Africa and Asia, are now pan-tropical and in ecological terms considered an indicator of overgrazed, disturbed lands; they grow successfully in dry areas. Variations in water relations, morphology and photosynthesis of the two species growing in the same habitat were studied to assess possible mechanis...
متن کاملAssessment of Health Conditions of Mountain Rangeland Ecosystem Using Species Diversity and Richness Indices, Case Study: Central Alborz (Iran)
Based on the importance and role of species diversity and richness as ameasurement of the health of an ecosystem; studying of their components can lead toevaluate the health condition of rangeland. This research was carried out in a part ofhighland mountainous rangeland of Mount Alborz Range in Iran. Diversity and richnesswere assessed as an ecosystem health indicator. The study area was locate...

متن کاملPlant species richness and ecosystem multifunctionality in global drylands.
Experiments suggest that biodiversity enhances the ability of ecosystems to maintain multiple functions, such as carbon storage, productivity, and the buildup of nutrient pools (multifunctionality). However, the relationship between biodiversity and multifunctionality has never been assessed globally in natural ecosystems. We report here on a global empirical study relating plant species richne...
