Mapping the Geography of Fungal Toxins: How Aspergillus flavus Populations Reveal a More Complex Risk

Close-up of Aspergillus flavus mold growth on corn kernels, representing aflatoxin contamination risk that varies by geographic fungal population

Aspergillus flavus populations differ significantly across regions in genetic structure, metabolic behavior, and aflatoxin-production capacity. A 2026 multi-omics study shows that species-level identification alone is insufficient for accurate mycotoxin risk assessment.

Land Use and Soil Fungal Risk: What a Global Dataset Tells Land Managers

A global analysis of 511 soil samples finds that surrounding landscape structure — not just local soil conditions — significantly shapes pathogenic fungal diversity. Crop-dominated areas show higher pathogen diversity; vegetation buffers show the reverse.

Plant Alarm Signals: How Oxylipins May Help Crops Fight Climate-Driven Mold and Mycotoxins

Plants are not passive when fungi attack. Their internal signaling chemistry — including molecules called oxylipins — helps determine whether fungal invasion succeeds and toxins accumulate. Climate stress is disrupting those defenses, and researchers are paying attention.

Antarctic Plants Face Growing Threat from Expanding Fungal Diseases

Scientists warn that rising temperatures may allow fungal diseases to spread within Antarctica’s fragile plant ecosystems. The report examines how climate change, increased moisture, and human activity could introduce new biological threats to polar biodiversity, raising concerns about ecosystem resilience, pathogen expansion, and long-term environmental stability in Antarctica.

When Mold Moves North: Climate Change and the New Geography of Aspergillus Risk

Climate change is shifting the global geography of Aspergillus — the fungi behind aspergillosis, aflatoxin contamination, and antifungal resistance. A new modeling study maps where fungal risk may be moving, and why it matters for health and agriculture.

Rising Temperatures May Increase Fungal Threats to Human Health, Researchers Warn

Researchers warn that rising temperatures may help fungi adapt to warmer environments, potentially increasing human infection risks. The report explores climate-driven fungal evolution, antifungal resistance, and species such as Candida auris. Scientists emphasize the need for fungal surveillance, medical research, and climate-aware public health strategies worldwide.

Fungal Disease and Climate Change Put Colorado’s Peach Industry at Risk

Colorado peach orchards face increasing threats from fungal diseases and climate change. Warmer temperatures, irregular weather, and moisture fluctuations create favorable conditions for pathogens such as brown rot. Growers are adapting through orchard management, resistant varieties, and disease monitoring while researchers study long-term solutions for sustainable peach production.
