Abstract Predicting how changes in weather patterns and land use jointly impact populations is a pressing task ecology. Microclimate may play key role species’ local persistence by modulating regional effects. We lack sufficient empirical evidence to understand the relative effects of landscape structure habitat conditions on intraspecific trait variation. Using spatially temporally replicated demographic dataset, we tested effect (area connectivity remnant fragments), microclimate (heat load), fluctuation (study year) plant variation, investigated whether heat load modulated studied traits. performed repeated measurements stem height, leaf area, number stems, main inflorescence length primary side inflorescencesof 569 permanently marked individuals grassland specialist Salvia nemorosa L. sampled 13 encompassing microhabitats exposed different levels, over three consecutive years. Mature had fewer stems isolated, taller small fragments. High levels dry years affected negatively all measured traits, negative exposure high were generally exacerbated Exposure strong environmental stressors could ultimately obscure real human populations. Landscape planning for conservation species should ensure not only improved but also high-quality habitats with heterogeneous microclimates able buffer extremes.
