Global diversity of drought tolerance and grassland climate-change resilience
Drought reduces plant productivity, induces widespread plant mortality and limits the geographic distribution of plant species1–7. As climates warm and precipitation patterns shift in the future8,9, understanding the distribution of the diversity of plant drought tolerance is central to predicting future ecosystem function and resilience to climate change10–12. These questions are especially pr...
متن کاملWhen competition does not matter: grassland diversity and community composition.
We examined whether the intense root competition in a rough fescue grassland plant community in central Alberta, Canada, was important in structuring plant species diversity or community composition. We measured competition intensity across gradients of species richness, evenness, and community composition, using pairs of naturally occurring plants of 12 species. One plant in each pair was isol...
متن کاملUsing Regional Climate Projections to Guide Grassland Community Restoration in the Face of Climate Change
Grassland loss has been extensive worldwide, endangering the associated biodiversity and human well-being that are both dependent on these ecosystems. Ecologists have developed approaches to restore grassland communities and many have been successful, particularly where soils are rich, precipitation is abundant, and seeds of native plant species can be obtained. However, climate change adds a n...
متن کاملCommunity and ecosystem effects of intraspecific genetic diversity in grassland microcosms of varying species diversity.
Studies of whether plant community structure and ecosystem properties depend on the genetic diversity of component populations have been largely restricted to species monocultures and have involved levels of genetic differentiation that do not necessarily correspond to that exhibited by neighboring mature individuals in the field. We established experimental communities of varying intraspecific...
متن کاملInvasibility and compositional stability in a grassland community: relationships to diversity and extrinsic factors
We present results from an ongoing field study conducted in Kansas grassland to examine correlates of invasibility and community stability along a natural gradient of plant diversity. Invasibility was evaluated by sowing seeds of 34 plant species into 40 experimental plots and then measuring colonization success after two growing seasons. Compositional stability, defined as resistance to change...
