Role of Arbuscular Mycorrhizal Fungi in Regulating Growth, Enhancing Productivity, and Potentially Influencing Ecosystems under Abiotic and Biotic Stresses

Plants, Journal Year: 2023, Volume and Issue: 12(17), P. 3102 - 3102

Published: Aug. 29, 2023

Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with the roots of nearly all land-dwelling plants, increasing growth and productivity, especially during abiotic stress. AMF improves plant development by improving nutrient acquisition, such as phosphorus, water, mineral uptake. tolerance resilience to stressors drought, salt, heavy metal toxicity. These benefits come from arbuscular interface, which lets fungal partners exchange nutrients, signalling molecules, protective chemical compounds. Plants' antioxidant defence systems, osmotic adjustment, hormone regulation are also affected infestation. responses promote performance, photosynthetic efficiency, biomass production in stress conditions. As a result its positive effects on soil structure, cycling, carbon sequestration, contributes maintenance resilient ecosystems. The AMFs ecological stability species- environment-specific.

Demystifying ecological connectivity for actionable spatial conservation planning

Trends in Ecology & Evolution, Journal Year: 2022, Volume and Issue: 37(12), P. 1079 - 1091

There is a disconnect between global high-level conservation goals and on-the-ground actions such as maintaining ecosystem services or persistence local planning of protected areas.Dynamic processes ecological connectivity underpin species resilience but are difficult to represent in mathematical spatial problems for areas.Quantitative SMART (specific – measurable action-oriented realistic time-bound) objectives can provide link regional design implementation functionally connected area networks.With current gaps commitments increasing climate change threats, there tremendous opportunity use quantifiable vehicle future-proof networks help achieve goals. Connectivity underpins the life; it needs inform biodiversity decisions. Yet, when prioritising areas developing actions, not being operationalised planning.

Current food trade helps mitigate future climate change impacts in lower-income nations

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(1), P. e0314722 - e0314722

Published: Jan. 3, 2025

The risk of national food supply disruptions is linked to both domestic production and imports. But assessments climate change risks for systems typically focus on the impacts production, ignoring in supplying regions. Here, we use global crop modeling data combination with current trade flows evaluate potential supply, comparing alone (domestic impacts) considering how all source regions (consumption impact). Under 2°C additional mean warming over present day, our analysis highlights that are aggravated 53% high income 56% upper medium countries mitigated 60% low- 71% low-medium under consumption-based compared alone. We find many reliant a few mega-exporters who mediate these impacts. Managing security requires perspective, not only affected, but also affects trading partners.
