Biogeochemical weathering under ice: Size matters
[1] The basal regions of continental ice sheets are gaps in our current understanding of the Earth’s biosphere and biogeochemical cycles. We draw on existing and new chemical data sets for subglacial meltwaters to provide the first comprehensive assessment of sub‐ice sheet biogeochemical weathering. We show that size of the ice mass is a critical control on the balance of chemical weathering pr...
متن کاملSize matters
Charles Darwin when developing his theory of evolution. And a new study of work on the islands' marine iguanas may help throw some more light on the evolution of body size within these populations. Body size is one of the most important traits of organisms and allows predictions of an individual's morphology, physiology, behaviour and life history. However, explaining the evolution of such comp...
متن کاملMatters of Size
Size does matter. At least that’s what the tagline of the movie Godzilla claims (one of the many renditions of the franchise). A quick glance at the great beasts of our past—dinosaurs, marine animals, snakes, why even disturbingly massive dragonflies, scorpions and camels—would make it appear as if increased body size conferred some sort of advantage then. Yet biologists concur that overall, th...
متن کامل(Genome) size matters.
The quotation above has led to the commonly held view that all bacteria will eventually become resistant to any antibiotic given enough time and exposure. However not all bacteria develop resistance to antibiotics at the same rate (and perhaps some species of bacteria may never develop resistance to certain antibiotics). And some bacteria that have been labeled “resistant” are not, in any clini...
متن کاملSize Matters. Does Bias?
Most empirical disciplines promote the reuse and sharing of datasets, as it leads to greater possibility of replication. While this is increasingly the case in Empirical Software Engineering, some of the most popular bug-fix datasets are now known to be biased. This raises two significants concerns: first, that sample bias may lead to underperforming prediction models, and second, that the exte...
