1. Assemblage similarity decays with geographic distance—a pattern known as the distance-decay relationship. While this pattern has been investigated for a wide range of organisms, ecosystems, and geographical gradients, whether these changes vary more cryptically across different forest strata (from ground to canopy) remains elusive. 2. Here, we investigated the influence of ground vs arboreal assemblages to the general distance-decay relationship observed in forests. We seek to explain differences in distance-decay relationships between strata in...

Data comprise wood specific gravity (WSG) and density at 12% moisture content (D12) in wood cores sampled from trees in the Ankeniheny Zahamena forest corridor, the remains of the evergreen forest of eastern Madagascar. The data also include date of sample collection, zone identifier, core identifier, local and scientific tree name, tree height and diameter. Samples were analysed by UFR Sciences du bois de l'ESSA-forêts, Université d'Antananarivo. Data were collected as part of a project...
