Avian Taxonomy & Systematics

Reassessing Hidden Avian Diversity in the South Asian Tropics

This project investigates avian diversity and diversification across the South Asian tropics, with a focus on the Western Ghats and Sri Lanka—one of the world’s most important biodiversity hotspots. Despite their exceptional biological richness, these regions have been relatively underrepresented in modern molecular phylogenetic and phylogeographic studies of birds.

Our research aims to reassess species limits and uncover previously unrecognized avian diversity using an integrative, lineage-based approach that combines genomic, phenotypic, and ecological data. By doing so, we seek to provide a comprehensive understanding of regional avifaunal diversity, patterns of endemism, and the historical processes that have shaped bird diversification across the Indian Subcontinent.

The project focuses on approximately 20 avian lineages, prioritizing endemic taxa and geographically isolated populations. Sampling is designed to capture variation across historically recognized subspecies, distinct phenotypes, and major geographic regions.

To address these questions, we integrate multiple cutting-edge approaches, including whole-genome sequencing, coalescent-based genetic analyses, phylogenetic inference, ecological niche modeling, and phenotypic analyses based on both museum specimens and field observations.

By revealing hidden diversity and clarifying evolutionary relationships, this research will have important implications for conservation. Improved taxonomic understanding can inform conservation status assessments and guide the design and management of protected areas within this globally significant biodiversity hotspot.

The project will generate genomic datasets and specimen resources for future biodiversity research, while also supporting undergraduate research and training at the University of Utah.
