Data from: Niche construction affects the variability and strength of natural selection

Consideration of the properties of the sources of selection potentially
helps biologists to account for variation in selection. Here we explore
how the variability of natural selection is affected by organisms that
regulate the experienced environment through their activities (whether by
constructing components of their local environments such as nests,
burrows, or pupal cases, or by choosing suitable resources). Specifically,
we test the prediction that organism-constructed sources of selection that
buffer environmental variation will result in reduced variation in
selection gradients, including reduced variation between (i) years
(temporal variation), and (ii) locations (spatial variation), and (iii)
weaker directional selection, relative to non-constructed sources. Using
compiled datasets of 1045 temporally replicated, 257 spatially replicated,
and a pooled dataset of 1230 selection gradients, we find compelling
evidence for reduced temporal variation and weaker selection, in response
to constructed compared to non-constructed sources, and some evidence for
reduced spatial variation in selection. These findings, which remained
robust to alternative datasets, taxa, analytical methods, definitions of
constructed/non-constructed, and other tests of reliability, suggest that
organism-manufactured or chosen components of environments may have
qualitatively different properties from other environmental features.
