Topic trends
Dominant research themes and year-over-year shifts in Botany and Plant Ecology Studies
What Topics Define the Class of 2026?
In the Class of 2026 for Botany and Plant Ecology Studies, functional diversity, ecosystem multifunctionality, and microbial community emerged as the most dominant themes. The high frequency of these topics indicates a strong emphasis on understanding how different plant species and microbial communities interact to support complex ecosystem processes. Researchers are increasingly focusing on how biodiversity directly impacts ecosystem resilience and the multifaceted services that these ecosystems provide. Additionally, significant attention was given to species diversity, soil moisture, and phytoremediation. The prominence of arbuscular mycorrhizal fungi further highlights the critical role of below-ground interactions and symbioses in shaping above-ground plant health and community structure. Together, these topics reflect a paradigm shift towards holistic, trait-based approaches that integrate microbial dynamics and functional traits to better predict ecological outcomes in varying environments.

How Did Topics Shift from the Class of 2025 to the Class of 2026?
The transition from the Class of 2025 to the Class of 2026 revealed notable shifts in research priorities within Botany and Plant Ecology. We observed significant surges in topics related to microbial diversity, phytoremediation, and carbon storage, reflecting an urgent shift toward applied ecological solutions and climate change mitigation strategies. Climate warming and arbuscular mycorrhizal fungi also saw substantial increases, underscoring a growing recognition of the interconnectedness of climate stressors and symbiotic soil interactions. Conversely, more traditional descriptive approaches such as floristic inventory, along with specific studies on bryophytes, mosses, and alpine meadows, experienced relative declines. This shift suggests that the field is moving rapidly from cataloging plant life and studying isolated ecological niches toward functional, systems-level analyses aimed at addressing global environmental challenges.

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.
