Casting your network wide: a plea to scale-up phenological research

Area of Science:

• Ecology
• Environmental Science
• Climate Change Biology

Background:

• Scientific evidence shows widespread shifts in biological seasons.
• These phenological shifts can alter interspecific interactions, affecting species' reproductive success and survival.
• Current understanding is limited by studies using a simplified food-chain model at local scales.

Purpose of the Study:

• To broaden the scope of phenological studies beyond local, bottom-up food chains.
• To incorporate food-web interactions and landscape-scale processes across diverse ecosystems.
• To develop a general understanding of systems most vulnerable to phenological synchrony effects.

Main Methods:

• Critique of existing 'bottom-up' food-chain paradigm in phenological research.
• Proposal for integrating food-web dynamics and landscape ecology into phenological studies.
• Advocacy for multi-ecosystem research and sentinel sites for integrated monitoring.

Main Results:

• Current research is insufficient due to its limited scope and simplified models.
• A holistic approach is necessary to accurately assess the impacts of phenological shifts.
• Identifying vulnerable systems requires a broader, integrated research framework.

Conclusions:

• Wider scope incorporating food webs and landscape processes is crucial for understanding phenological shifts.
• Sentinel sites for co-located predator-prey monitoring are proposed as a key first step.
• Developing a generic understanding of vulnerable systems is essential for future ecological forecasting.
