TL;DR: Using a > 15 year soil warming experiment in a mid-latitude forest, it is shown that the apparent 'acclimation' of soil respiration at the ecosystem scale results from combined effects of reductions in soil carbon pools and microbial biomass, and thermal adaptation of microbial respiration.

TL;DR: In this paper, the authors couple isotope, soil C fractionation and mesocosm techniques to assess the sequestration of plant-C inputs, and their partitioning into C pools with different sink potentials, under an experimental gradient of N and P deposition.

TL;DR: New and published carbon and oxygen isotopic data taken from large-bodied fossil mammals, and pedogenic carbonates in fossil soils from East Turkana in northern Kenya suggest that a dietary shift from C3 to C4 resources occurred in the genus Homo circa 1.65 million years ago despite palaeoenvironmental continuity.

TL;DR: Why the substrate-depletion hypothesis may not solely explain observed responses, and why caution is urged in interpretation of the seasonal data, is described.

TL;DR: An instrument that provides precise estimates of egg volume and can be easily used in the field is developed that is both precise and accurate and combined with other techniques so that both eggVolume and embryonic stage can be estimated at the same time.
