Results of study on prairie grasslands show differences across the months Does it matter whether long periods of hot weather, such as last year's heat wave that gripped the U.S. Midwest, happen in June or July, August or September? Scientists studying the subtle effects of heat waves and droughts say that when such events happen makes a big difference. Based on more than 25 years of data from the National Science Foundation (NSF) Konza Prairie Long-Term Ecological Research (LTER)...

Scientists address sustainability of agriculture; urban water systems; indigenous villages; marine environments From Canada to Chile, from Kazakhstan to Kansas, we are witnessing a fast-changing planet. What will it look like in the years, decades and centuries to come? How far, and in what ways, can Earth's systems be stressed before they undergo transitions to new states--with unforeseen consequences? For most of its history, Earth experienced vast alterations in response to...

Scientists address climate change effects on ecosystems from grasslands to forests to open ocean Human activities such as burning of fossil fuels and land use change have increased atmospheric carbon dioxide by 40 percent since the start of the industrial revolution, researchers have found. The result is a hotter Earth, with warmer average temperatures around the globe and a future climate system that will be more variable, and with more extreme events, says Scott Collins, a scientist at the...

By Mark Vierthaler, Journal-World, Lawrence, Kan. Aug. 4--No one is quite sure how the world's ecosystems are changing. A new program, however, is aiming to fix that. Nature preserves at Kansas University and Kansas State University are potential candidates for a fledgling observation network on how global changes affect the Earth's ecosystem. Leonard Krishtalka, a professor in KU's department of ecology and evolutionary biology and director of the Natural History Museum and...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.'

'Copp' is still found in the word 'cobweb.'
