Measuring microbial respiration in soils collected for three years along a latitudinal gradient, the authors find lower respiration rates and greater plasticity in responses at sites with higher mean annual temperatures, consistent with adaptation to thermal regimes.
Undertaking an incubation study on soil collected from 110 dryland sites across the world, the authors show that the response of soil microbial respiration to temperature is consistent with that of adaptation to the ambient thermal regime.
Comparison of nuclear and mitochondrial ancestry in admixed human populations from the Americas shows mitonuclear interactions with possible impacts on phenotypic variation in admixed individuals.
Sixteen-month manipulation experiments in a degraded macroalgae-dominated tropical reef setting show that lower coral species richness suppresses growth and survivorship of multiple species.
