Seasonally different response of photosynthetic activity to daytime and night-time warming in the Northern Hemisphere.
Over the last century the Northern Hemisphere has experienced rapid climate warming, but this warming has not been evenly distributed seasonally, as well as diurnally. The implications of such seasonal and diurnal heterogeneous warming on regional and global vegetation photosynthetic activity, however, are still poorly understood. Here, we investigated for different seasons how photosynthetic a...
متن کاملTrade-offs between global warming and day length on the start of the carbon uptake period in seasonally cold ecosystems
It is well established that warming leads to longer growing seasons in seasonally cold ecosystems. Whether this goes along with an increase in the net ecosystem carbon dioxide (CO2) uptake is much more controversial. We studied the effects of warming on the start of the carbon uptake period (CUP) of three mountain grasslands situated along an elevational gradient in the Alps. To this end we use...
متن کاملWalking on Uneven Terrain
Control of legged locomotion across uneven terrain is poorly understood from a theoretical perspective, despite strong relevance to clinical and robotic applications. Gait research has typically examined locomotion on smooth and level surfaces with uniform steps. Identifying key gait parameters that permit agile locomotion across uneven surfaces could lead to a clearer understanding of control ...
متن کاملCrack patterns over uneven substrates.
Cracks in thin layers are influenced by what lies beneath them. From buried craters to crocodile skin, crack patterns are found over an enormous range of length scales. Regardless of absolute size, their substrates can dramatically influence how cracks form, guiding them in some cases, or shielding regions from them in others. Here we investigate how a substrate's shape affects the appearance o...
متن کاملThe uneven experience of racism
Racism may well be an affect of despair. Racism may also be a central cause of despair. A telephone survey in the states of Queensland and NSW (sample 5056) examined the extent and distribution of experiences of racism. About 15 percent of Australians have experienced racism within the workplace and in education. About one-quarter of Australians report the experience of ‘everyday racisms’, such...
