abstract this chapter describes how the climate change is potentially the mostsevere threat to pollinator biodiversity. mounting evidence demonstrates that therehave already been biotic responses to the relatively small climate changes that haveoccurred this century. pollinators such as birds, bees, butterflies, moths, flies, wasps,beetles bats and even mosquitoes are essential for food product...

planet’s climate is changing, that human actions are the most likely dominant cause and that a major response is required, both to reduce the likelihood of disruptive climate change and to adapt to the change which is already under way. “Today the level of carbon dioxide in the atmophere is close to 390ppm, higher than at any time in the past 800,000 years,” warns glaciologist Robert Mulvaney o...

The current threat of global warming and the public demand for confident projections of climate change pose the ultimate challenge to science: predicting the future behaviour of a system of such overwhelming complexity as the Earth's climate. This Theme Issue addresses two practical problems that make even prediction of the statistical properties of the climate, when treated as the attractor of...

More than 85 percent of Australian terrestrial genera with a body mass exceeding 44 kilograms became extinct in the Late Pleistocene. Although most were marsupials, the list includes the large, flightless mihirung Genyornis newtoni. More than 700 dates onGenyornis eggshells from three different climate regions document the continuous presence of Genyornis from more than 100,000 years ago until ...

agricultural land conversion (alc) has been introduced as one of the most important factorsaffecting ecosystem. this type of conversion has led to several challenges in agricultural development andhuman life. monitoring alc plays a crucial role when dealing with such challenges. the main objective of thisstudywas to monitor the trend ofalc in theqazvin province located in northwest iran from 19...

prediction of climatic variables on a local scale by general circulation models of the atmosphere is impossible because the models have large-scale network of resolution. therefore, downscaling methods are used to solve this problem. since the climate change phenomenon can affect different systems such as, water resources, agriculture, environment, industry and economy as well, selection of the...

the projected rainfall change under various scenarios is likely to have both positive and negative implications on agriculture and water supply because in rainfall pattern across the country. rise in rainfall is seen over all states except punjab, rajasthan and tamil nadu, which show slight decrease in precipitation in the future scenarios. marked increase in covering the western ghats and nort...
