It is everyones duty to do someting good to the environment around us.As middle school students, we can also do a lot of helpful things.For example, we can protect it by not throwing rubbish away.We can save water to make full use of it. We can use materials which do no harm to t...
(2000) concluded that the average Rh of multiple forest ecosystems accounted for about 50% of Rs, but to date there has been little agreement on the temporal and spatial patterns of Ra and Rh in postfire boreal forests. An increase or decrease in the heterotrophic component of Rs may lead...
How do forests affect the water cycle? What are some ways people polute a temperate forest? How does an ecological community recover from a fire? Why is a climax community stable? How do forest fires affect the biosphere? How do forests promote carbon sequestration?
How are forest biomes created? How do rain forests help to prevent the greenhouse effect? How does the climate system connect with nuclear power? How does climate change affect ecosystems? How does vegetation affect climate variability? How does the biosphere record changes in the climate system?
species inhabiting fire-prone ecosystems have often evolved tolerance mechanisms to regular low-level fires, but this may vary from species to species (Buchholz et al.2019). For all these reasons, a prominent open question is how a given fire regime (and changes to the regime brought about by...
As in many other fire-prone ecosystems, this species benefits from fire occurrence. These results indicate that the 'zero-fire' policy currently in place in the Brazilian savanna is inadequate for the conservation of this, and probably many other, Cerrado species....
Some ecosystems are already changing drastically due to a shift in climate. The University of Alberta reports that much of what once was tundra in northern Canada is turning into forests. They also noticed that the change from tundra to forest isn't linear; instead, it seems that the change...
Even with remarkable clean coal technologies, catalytic converters and strong caps and regulations, fossil fuels are still a dirty power source. Alternative forms of energy likenuclear, solar and hydropower do not emit the millions of tons of SO2 and NOx that upend ecosystems, blight buildings...
How do volcanoes affect water? Fire and Water: Both terrestrial and submarine volcanoes can impact the marine ecosystems of the world. They do this through physical processes of heat and pressure as well as through chemical processes of water combining with their emissions. ...
How do diverse ecosystems ensure resilience? Species diversity reinforces an ecosystem's resilienceby providing multiple species to perform the same function, allowing the ecosystem to recover more quickly in the event of a disturbance. ... Each of these ecosystems has different plant communities. ...
