Mayflies (Ephemeroptera) and Their Contributions to Ecosystem Services

Area of Science:

• Ecology
• Entomology
• Conservation Biology

Background:

• Ephemeroptera, commonly known as mayflies, are an order of insects found in freshwater ecosystems globally.
• They exhibit unique biological traits, including a distinct subimago stage and varied nymphal feeding strategies.
• Mayflies are nearly cosmopolitan, absent only from Antarctica and extremely remote islands.

Purpose of the Study:

• To provide a comprehensive overview of mayfly biology, diversity, and ecological services.
• To highlight the cultural, provisioning, regulatory, and supporting roles of mayflies in ecosystems.
• To assess the conservation status and threats facing mayfly populations worldwide.

Main Methods:

• Literature review and synthesis of existing research on Ephemeroptera.
• Analysis of mayfly ecological roles, including feeding, habitat provision, and indicator functions.
• Examination of conservation threats such as pollution, habitat degradation, and climate change.

Main Results:

• Mayflies offer significant cultural services (inspiration, festivals) and provisioning services (food, laboratory use, potential pharmaceuticals).
• They perform crucial regulatory services like freshwater cleaning and essential supporting services, including nutrient cycling and bioturbation.
• Approximately 20% of mayfly species are potentially threatened due to anthropogenic impacts and climate change.

Conclusions:

• Mayflies are integral to freshwater and terrestrial ecosystem health, providing a wide array of services.
• Conservation efforts are critical to protect mayfly diversity from threats like pollution and habitat loss.
• Balancing human needs, such as sustainable energy, with mayfly conservation presents complex challenges.
