Tropical mountain ecosystems harbor diverse biological communities, making them valuable models for exploring the factors that shape ecological interactions along environmental gradients. We investigated spatial and temporal drivers of plant-hummingbird interaction networks across three forest types (pine-oak, fir, subalpine) a tropical high gradient in western Mexico (2400 to 3700 m.a.s.l.). measured species abundance, diversity, morphology, frequencies. Plant diversity metrics significantly declined highest elevation subalpine forest, whereas hummingbird remained consistent elevations. Interaction were similarly nested elevations, but they more specialized where lower plant richness higher floral abundance led greater resource partitioning among hummingbirds. Plant-hummingbird larger less during dry season, driven by abundance.

Morphological matching low-elevation season. phylogenetic relatedness negligible effects patterns, phylogeny influenced feeding preferences high-elevation Our findings highlight role turnover, rewiring, phenological structuring with specific varying High-elevation play crucial as reservoirs resources both resident resource-scarce periods, emphasizing their importance maintaining biodiversity
