Tropical montane gradients elucidate the contributions of functional traits to competitive and environmental fitness

The paper examines functional traits in Himalayan bird communities along an elevation gradient, finding that traits previously classified as alpha or beta show complex relationships with elevation and fitness.

Testing a theoretical framework for the environment-species abundance paradigm: a new approach to the Abundant Centre Hypothesis

The paper tests the Abundant Centre Hypothesis by analyzing bird abundance data across an elevational transect, finding symmetric community profiles and elevation-dependent species asymmetry.

Taxonomic scale dependency of Bergmann's patterns: A cross-scale comparison of hawkmoths and birds along a tropical elevational gradient

This study compares Bergmann's patterns in hawkmoths and birds across different taxonomic scales along an elevational gradient, finding scale-dependent size-temperature relationships.

Functional randomness despite high taxonomic turnover across an elevational gradient in a global biodiversity hotspot: A case study of hawkmoths and birds

The paper examines taxonomic and functional dissimilarities in hawkmoths and birds across an elevational gradient, finding high taxonomic turnover with functional redundancy despite environmental changes.

Intraspecific trait variability and community assembly in hawkmoths (Lepidoptera: Sphingidae) across an elevational gradient in the eastern Himalayas, India

This study examines trait variation in hawkmoths across an elevational gradient and finds that community assembly is dominated by internal filtering, with intraspecific trait variation contributing to trait variability.

High throughput photogrammetric measurement of morphological traits in free-ranging phototropic insects

The paper introduces a non-invasive method for high-throughput morphometric measurement of free-ranging phototropic insects using calibrated digital images and open-source tools.
