Photosynthesis and growth reduction with warming are driven by nonstomatal limitations in a Mediterranean semi-arid shrub [PDF]

open access: yes, 2016
Whereas warming enhances plant nutrient status and photosynthesis in most terrestrial ecosystems, dryland vegetation is vulnerable to the likely increases in evapotranspiration and reductions in soil moisture caused by elevated temperatures.

Global-scale estimation of diffuse groundwater recharge : model tuning to local data for semi-arid and arid regions and assessment of climate change impact [PDF]

open access: yes, 2005
Groundwater recharge is the major limiting factor for the sustainable use of groundwater. To support water management in a globalized world, it is necessary to estimate, in a spatially resolved way, global-scale groundwater recharge.

Climate change could negate positive tree diversity effects on forest productivity: a study across five climate types in Spain and Canada [PDF]

open access: yes, 2017
A positive relationship between tree diversity and forest productivity is reported for many forested biomes of the world. However, whether tree diversity is able to increase the stability of forest growth to changes in climate is still an open question ...

The Marmara Sea Gateway since ~16 ky BP: non-catastrophic causes of paleoceanographic events in the Black Sea at 8.4 and 7.15 ky BP [PDF]

open access: yes, 2007
The Late Quaternary history of connection of the Black Sea to the Eastern Mediterranean has been intensely debated. Ryan, Pitman and coworkers advocate two pulses of outflow from the Black Sea to the world ocean at ~16–14.7 ky BP and ~11–10 ky BP ...

The influence of hot arid climate on the use of outdoor urban spaces and thermal comfort: do cultural and social backgrounds matter? [PDF]

open access: yes, 2010
Climate-sensitive open spaces within cities may benefit the three dimensions of sustainability affecting economic, social and environmental factors. Aiming to improve microclimatic conditions in urban spaces can enable people to spend more time outdoors,
