Empirically Derived Sensitivity of Vegetation to Climate across Global Gradients of Temperature and Precipitation
The natural composition of terrestrial ecosystems can be shaped by climate to take advantage of local environmental conditions. Ecosystem functioning (e.g., interaction between photosynthesis and temperature) can also acclimate to different climatological states. The combination of these two factors thus determines ecological– climate interactions.Aglobal empiricalmap of the sensitivity of vege...

متن کاملTree cover in Central Africa: determinants and sensitivity under contrasted scenarios of global change
Tree cover is a key variable for ecosystem functioning, and is widely used to study tropical ecosystems. But its determinants and their relative importance are still a matter of debate, especially because most regional and global analyses have not considered the influence of agricultural practices. More information is urgently needed regarding how human practices influence vegetation structure....
متن کاملChanges in the variability of global land precipitation
[1] In our warming climate there is a general expectation that the variability of precipitation (P) will increase at daily, monthly and inter-annual timescales. Here we analyse observations of monthly P (1940–2009) over the global land surface using a new theoretical framework that can distinguish changes in global P variance between space and time. We report a near-zero temporal trend in globa...
متن کاملStrong correlations between sensitivity and variability give rise to constant discrimination thresholds across the otolith afferent population.
The vestibular system is vital for our sense of linear self-motion. At the earliest processing stages, the otolith afferents of the vestibular nerve encode linear motion. Their resting discharge regularity has long been known to span a wide range, suggesting an important role in sensory coding, yet to date, the question of how this regularity alters the coding of translational motion is not ful...
