Effects of climate warming and declining species richness in grassland model ecosystems:acclimation of CO2 fluxes
climate warming declining species richness grassland model ecosystems CO2 fluxes
2010/1/14
To study the effects of warming and declining species richness on the carbon balance of grassland communities, model ecosystems containing one, three or nine species were exposed to ambient and elevat...
In Arctic Alaska, the Warming Climate Threatens an Ancient Culture（图）
Arctic Warming Climate Ancient Culture
2006/12/15
SHISHMAREF, Alaska—Over the past 10 years, while much of the United States has debated the potential threat of global climate change, nearly 600 residents of this remote island village have seen its e...
Warming mineralises young and old soil carbon equally
Warming mineralises young and old soil carbon
2010/1/13
The temperature sensitivity of soil organic carbon decomposition is critical for predicting future climate change because soils store 2-3 times the amount of atmospheric carbon. Of particular controve...
Twenty years of spatially coherent deepwater warming in lakes across Europe related to the North Atlantic Oscillation
spatially coherent deepwater across Europe
2014/5/5
Twenty to fifty years of annual mean deepwater (hypolimnetic) temperature data from twelve deep lakes
spaced across Europe (2u959W to 14u09E, 46u279 to 59u009N) show a high degree of coherence among ...
Response of Southern Ocean phytoplankton and bacterioplankton production to short-term experimental warming
Southern Ocean phytoplankton bacterioplankton production short-term experimental warming
2014/5/4
We examined the potential response of Southern Ocean pelagic ecosystems to warming through changes in total primary production (particulate plus dissolved = PPP + DPP) and bacterial production (BP), d...
We compare the physical mechanisms involved in the generation and decay of ENSO events in a control (present day conditions) and Scenario (Is92a, IPCC 1996) simulations performed with the coupled ocea...
El Niño Southern Oscillation (ENSO) and global warming
El Niñ o Southern Oscillation global warming
2010/1/25
It is widely accepted by the international scientific community that human activities have increased atmospheric concentrations of greenhouse gases (GHG) and aerosols since the pre-industrial era. Thi...
Effects of warming on benthic communities in a boreal lake: Implications of climate change
Effects of warming benthic communities boreal lake: Implications climate change
2014/5/13
We experimentally warmed a series of shallow enclosures by 4.5°C and measured responses of the epilithon (biofilm on rocky surfaces) and invertebrates. Maximum rates of net photosynthesis increased by...
Deep-water warming trend in Lake Malawi, East Africa
Deep-water warming trend Lake Malawi East Africa
2014/5/9
We use historic water temperature measurements to define a deep-water warming trend in Lake Malawi, East Africa. Over the past six decades, the temperature of the deep water below 300 m has increased ...
Effects of experimental greenhouse warming on phytoplankton and zooplankton communities in fishless alpine ponds
experimental greenhouse warming on phytoplankton zooplankton communities fishless alpine ponds
2014/5/19
The impacts of global warming on aquatic ecosystems are expected to be most pronounced at higher trophic levels in cold-water environments. Therefore, we hypothesized that warming of fishless alpine p...
Response of Lake Kivu stratification to lava inflow and climate warming
Lake Kivu stratification lava inflow climate warming
2014/5/14
During the eruption of Nyiragongo Volcano in January 2002 about 106 m3 of lava entered Lake Kivu. The high concentrations of CO2 and CH4 dissolved in the deep waters of Lake Kivu raised serious concer...
Complex effects of winter warming on the physicochemical characteristics of a deep lake

2014/5/21
Recent winter warming over Central Europe associated with a positive phase of the North Atlantic Oscillation
(NAO) strongly influenced the thermal and water column stability properties of deep ...
Climatic warming causes regime shifts in lake foodwebs
Climatic warming regime shifts lake food webs
2014/6/10
Spring clear water phases caused by grazing of zooplankton on algae are among the most spectacular and well-studied events in lake plankton dynamics. Such clear water phases are also important as wind...
