32 p, 2.4 MB Global hunter-gatherer population densities constrained by influence of seasonality on diet composition / Zhu, Dan (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Galbraith, Eric (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Reyes-García, Victoria (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Ciais, Philippe (The Cyprus Institute. Climate and Atmosphere Research Center)
The dependence of hunter-gatherers on local net primary production (NPP) to provide food played a major role in shaping long-term human population dynamics. Observations of contemporary hunter-gatherers have shown an overall correlation between population density and annual NPP, but with a thousand-fold variation in population density per unit NPP that remains unexplained.

4 p, 869.2 KB Quantifying the recarbonization of post-agricultural landscapes / Bell, Stephen Mackenzie (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Raymond, Samuel J. (Massachusetts Institute of Technology) ; Yin, He (Kent State University) ; Jiao, Wenzhe (Massachusetts Institute of Technology) ; Goll, Daniel S.

(Northern Arizona University) ; Terrer, César (Massachusetts Institute of Technology)
Despite worldwide prevalence, post-agricultural landscapes remain one of the least constrained human-induced land carbon sinks. To appraise their role in rebuilding the planet's natural carbon stocks through ecosystem restoration, we need to better understand their spatial and temporal legacies.

Institut de Ciència i Tecnologia Ambientals) ; Guenet, Bertrand (PSL Research University. Laboratoire de Géologie) ; Peng, Shushi (Peking University.

Geography Department) ; Charman, Dan J. (University of Exeter. Geography Department) ; Brewer, Simon C. (University of Utah. Department of Geography)
When a peatland is drained and cultivated, it behaves as a notable source of CO2. However, we lack temporally and spatially explicit estimates of carbon losses from cultivated peatlands. Using a process-based land surface model that explicitly includes representation of peatland processes, we estimate that northern peatlands con-verted to croplands emitted 72 Pg C over 850-2010, with 45% of this source having occurred before 1750.

Acid phosphatase produced by plants and microbes plays a fundamental role in the recycling of soil phosphorus (P). A quantification of the spatial variation in potential acid phosphatase activity (AP) on large spatial scales and its drivers can help to reduce the uncertainty in our understanding of bio-availability of soil P.

Institute of Geographic Sciences and Natural Resources Research)
Spring warming substantially advances leaf unfolding and flowering time for perennials. Winter warming, however, decreases chilling accumulation (CA), which increases the heat requirement (HR) and acts to delay spring phenology. [...]

Measuring leaf gas exchange from canopy leaves is fundamental for our understanding of photosynthesis and for a realistic representation of carbon uptake in vegetation models. Since canopy leaves are often difficult to reach, especially in tropical forests with emergent trees up to 60 m at remote places, canopy access techniques such as canopy cranes or towers have facilitated photosynthetic measurements.
