Ecology is the study of how organisms interact with each other and their environment. It considers processes that occur at the population, community and ecosystem levels and has a particular focus on biodiversity.
The magnitude of organic carbon burial in lakes and reservoirs is poorly constrained. Here, using a compilation of modern data from the literature and statistical modeling, the authors estimate a global yearly organic carbon burial of 0.15 Pg C in inland waters, of which 40% is stored in reservoirs.
It is unclear whether the transfer of plasmids carrying antibiotic resistance genes can explain their persistence when antibiotics are not present. Here, Lopatkin et al. show that conjugal plasmids, even when costly, are indeed transferred at sufficiently high rates to be maintained in the absence of antibiotics.
The terrestrial carbon cycle is strongly influenced by El Niño/Southern Oscillation (ENSO), but how this relationship will change in future is not clear. Here the authors use state-of-the-art models to show that the sensitivity of the carbon cycle to ENSO will increase under future climate change.
A super-hydrated clay mineral may play an important role in the solid Earth’s water cycle, according to laboratory experiments. The mineral kaolinite can carry and release large amounts of water during subduction.
Studying eco-evolutionary dynamics in nature is challenging. In this Perspective, the authors discuss how genomic data can be used to understand the mechanisms behind eco-evolutionary dynamics and lead to evolutionary and ecological predictions in nature.
An increase in biodiversity 450 million years ago coincided with a rise in atmospheric oxygen concentrations, suggests a geochemical analysis. Oxygen availability may have thus helped spur the radiation alongside climatic cooling.
Adaptive certification is the best remaining option for the trophy hunting industry in Africa to demonstrate sustainable and ethical hunting practices that benefit local communities and wildlife conservation.
Microbial activity in the sea results in a loss of bioavailable nitrogen. It emerges that the climate phenomenon called the El Niño–Southern Oscillation has a surprisingly large effect on the size of this loss.
The Paris Agreement has increased the incentive to verify reported anthropogenic carbon dioxide emissions with independent Earth system observations. Reliable verification requires a step change in our understanding of carbon cycle variability.
