Накратко на български

Микоризните гъби, които помагат на корените на растенията да усвояват вода и хранителни вещества, се изследват при различни нива на засушаване и паша. Това помага да се разбере как тези гъби поддържат сухите екосистеми при промяна на климата.

The contribution of mycorrhizal fungi to multifunctionality in global drylands

Dryland ecosystems cover 45% of the Earth´s surface and support over 38% of the total global population, being a key terrestrial biome. Their functioning and the goods and services they provide are vulnerable to land degradation and desertification, which are exacerbated by global environmental change drivers such as increasing land-use intensity and climate aridification. Mycorrhizal fungi, i.e. obligate plant symbionts colonizing the roots of 90% of all land plants, contribute substantially to dryland diversity and functioning and the goods and services provided by drylands. These fungi trade their benefits in terms of increased nutrient uptake and water availability with the plants in exchange for photosynthetically acquired carbon. Carbon trade and hence plant-mycorrhizal interactions and their effect on ecosystem functioning will consequently depend on the plant economic strategies present in the vegetation, but we lack an understanding of the exact mechanism yet. We also do not know how the contribution of mycorrhizal fungi to the functioning of drylands might change under forecasted climate aridification and increasing grazing pressure, two major landmarks of global environmental change in these ecosystems. To fill these knowledge gaps the MYFUN project aimed to assess the relative contribution of the most common types of mycorrhizal fungi (AM and ECM fungi) to the multifunctionality of drylands in response to environmental stress (increased aridity, grazing pressure) and plant functional diversity in resource use economy.

Цел на проекта

Dryland ecosystems are a key terrestrial biome, covering 45% of the Earth´s surface and supporting over 38% of the total global population, but their functioning and the goods and services they provide are vulnerable to global environmental changes such as increasing land use intensity (e.g. grazing pressure) and climate aridification. Mycorrhizal fungi, i.e. obligate plant symbionts colonizing the roots of 90% of all land plants, contribute substantially to dryland biodiversity, to their functioning, and the provision of goods and services by dryland ecosystems. In exchange for plant assimilated carbon, mycorrhizal fungi increase plant nutrient supply, influence soil formation and aggregation, plant defence to herbivory and resistance to drought, among other important processes. Through these mechanisms, they influence plant diversity, multiple ecosystem functions, such as nutrient cycling or biomass production, and likely modulate ecosystem responses to aridity and grazing pressure, which are forecasted to increase in drylands under global environmental change. Mycorrhizal effects depend on environmental conditions and species traits determining the efficiency of the resource exchange between plants and fungi. However, to date little is known about the contribution of mycorrhizal fungi to the diversity and functioning of drylands or to the capacity of drylands to provide multiple functions simultaneously (i.e. multifunctionality). We also do not know how the contribution of mycorrhizal fungi to dryland multifunctionality might change under forecasted global environmental change or depending on the resource economy of the plant community. The MYFUN project aims to fill these gaps in knowledge by assessing the contribution of mycorrhizal fungi to dryland multifunctionality in response to environmental stress (increased aridity, grazing pressure) and plant resource economy.
