<p>Comprehensive raw dataset of architectural, edaphic, and micro-climatic variables for <i>Atta</i> colonies.</p>

Species identity is specified under the <i>Species</i> column, which comprises <i>A. cephalotes</i> (n = 56), <i>A. laevigata</i> (n = 58), and three colonies designated as U (n = 3), denoting individuals of ambiguous micro-habitat x morphology that could not be confidently classified to the species level in the field; these three unclassified colonies were included in the raw metadata for transparency but were systematically excluded from downstream species-specific statistical analyses.

Column headers are defined as follows: <i>Num_Col</i> represents the unique numerical identifier assigned to each sampled nest; <i>Location</i> denotes the specific geographic site of collection (spanning 12 distinct sampling localities); <i>Date_Fieldwork</i> indicates the exact date of data collection; and <i>Species</i> identifies the target organism. Structural parameters include mound <i>Length</i> (cm), <i>Width</i> (cm), and <i>Number_Active_Holes</i>.
