Class of 2026 (Papers Published in 2024)

What topics and trends defined most-cited Avian ecology and behavior research in the Class of 2026?

The Class of 2026 in avian ecology is dominated by research on migration phenology, stopover site conservation, and the devastating impacts of Highly Pathogenic Avian Influenza (HPAI). A notable shift from 2025 includes increased focus on the East Asian-Australasian Flyway and evaluating agri-environment schemes to mitigate agricultural intensification.

Methodology

PRI identifies high-impact research using a transparent, topic-agnostic framework applied consistently across scientific domains. Bibliographic records are drawn from OpenAlex, including publication dates, citation relationships, and document types.

This ranking covers the Class of 2026 cohort: journal articles published in 2024. Reviews and other non-article document types are excluded to ensure comparability.

Research impact is quantified with an 18-month post-publication citation window—the number of citing works published within 18 months of each paper's publication date. This metric captures early impact while controlling for publication age.

An LLM-based relevance classifier then reviews each candidate's title and abstract to confirm substantive alignment with the target domain. Only papers classified as relevant appear in the final ranking.
