Three of these had disproportionately high species turnover rates and shared a set of distinct geomorphological features like the maximum elevation of the watershed, high flow accumulation values at the outlet and at an elevation of 800 m and a high concavity of the longitudinal river profile. Other variables like landscape heterogeneity along the main river channel and length of the coastal plain further helped to differentiate between rivers with intermediate turnover rates.

Although on the basis of evolutionary theory, the patterns and drivers of intraspecific functional variation remain largely underexplored. In ants, pilosity and body size are morphological traits associated to thermoregulation and heat tolerance, which are critical concerns in the context of global warming.

Functional evenness decreased monotonically with elevation, while functional divergence increased at low elevations and again near the treeline. Phylogenetic diversity exhibited a monotonic decline accompanied by increased phylogenetic clustering at higher elevations. The mid-elevation collapse of functional richness was likely caused by trophic interactions. Reduced the availability of large fruits caused declines in frugivore body size and beak dimensions, while high abundance of invertebrates favoured functionally uniform insectivores. Near the treeline, bird communities displayed morphological shifts towards terrestrial lifestyles with reduced dispersal ability, suggesting environmental filtering by forest structure.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;By examining trends in individual functional traits, we highlight the role of trophic interactions in shaping avian functional diversity in tropical montane systems.
