Integrating multiple evidence streams to understand insect biodiversity change

Area of Science:

• Ecology
• Biodiversity Science
• Conservation Biology

Background:

• Insects represent a vast majority of animal species diversity but are threatened by human activities.
• Assessing insect biodiversity change is complicated by their complex ecology and fragmented scientific understanding.
• General statements about insect populations are difficult due to knowledge gaps.

Purpose of the Study:

• To discuss the challenges inherent in assessing insect biodiversity change.
• To propose an integrated approach for synthesizing evidence on insect biodiversity responses to environmental drivers.
• To enable rapid assessments of insect biodiversity in the face of accelerating anthropogenic impacts.

Main Methods:

• Reviewing and synthesizing multiple lines of evidence, including time-series data, spatial comparisons, experimental results, and expert opinions.
• Developing a framework to integrate diverse data sources for a comprehensive overview of insect biodiversity.
• Focusing on how insect biodiversity responds to various environmental drivers.

Main Results:

• The proposed integrated approach can overcome challenges posed by fragmented knowledge.
• This method allows for a synthesis of how insect biodiversity reacts to different drivers of change.
• It facilitates the generation of testable predictions regarding insect biodiversity across various scales.

Conclusions:

• Integrating multiple lines of evidence is crucial for a robust assessment of insect biodiversity.
• The proposed approach offers a pathway to rapid and reliable assessments of insect biodiversity change.
• This is vital for informing conservation strategies amidst escalating global environmental changes.
