Across ecosystems, canopy height sets a limit to vegetation volume, which, combined with vegetation fill, should determine the amount of structures and resources available to animal populations; the structural complexity of the vegetation should, in turn, promote niche differentiation. To facilitate future animal diversity studies, we address how these structural variables covary with each other across an elevation gradient in a biodiversity hotspot where climate and ecosystem productivity are well characterised.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Location</h3>\u0000 \u0000 <p>3800 m elevation gradient on the Eastern slopes of the tropical Andes.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Time Period</h3>\u0000 \u0000 <p>Present day.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Major Taxa Studied</h3>\u0000 \u0000 <p>Terrestrial plants.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We used land surveys and digital photographs to assess the structure and complexity of the vegetation along the 3800 m gradient, quantifying complexity using information theory metrics.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Whereas canopy height decreased with elevation, the density of the vegetation inside the forest increased monotonically as elevation increased, causing the amount of vegetation structures to peak at mid-elevations.

The phylogenetically distant species &lt;i&gt;T. aphylla&lt;/i&gt; and &lt;i&gt;T. hispida&lt;/i&gt; took intermediate positions. &lt;i&gt;Tamarix ramosissima&lt;/i&gt;, which grows in regions with cold winters and hot-dry summers, exhibited the most negative &lt;i&gt;P&lt;/i&gt;&lt;sub&gt;50&lt;/sub&gt; values, indicative of a low susceptibility to a failure of the water-conducting system.

This geographic history has important implications for the evolution of dispersal-limited forest-dwelling arthropods, such as Opiliones, which can help us reconstruct key past biogeographic events.
