Vanessa Buzzard, University of Arizona Department of Ecology and Evolutionary Biology The size and age of plants has more of an impact on their productivity than temperature and precipitation, University of Arizona researchers have discovered. UA professor Brian Enquist and postdoctoral researcher Sean Michaletz, along with collaborators Dongliang Cheng from Fujian Normal University in China and Drew Kerkhoff from Kenyon College in Gambier, Ohio, have combined a new mathematical theory...

Plants Develop Competitive Strategies In Extreme Desert Environments
2014-01-01 06:53:13

redOrbit Staff & Wire Reports - Your Universe Online Plants in extreme desert environments develop effective strategies to compete for the area’s limited resources, according to new research out of the University of Arizona published in the American Journal of Botany. Although deserts are often thought of as barren, inhospitable places, numerous plants and animals have adapted to this harsh environment, where they are often forced to compete with rivals for scarce resources such...

There Is A Limit For How Long Plants Can Adapt To Drought
2013-01-23 13:50:15

University of Arizona Plants can adapt their demand for water depending on how much is available - However, this resilience has a limit, and prolonged drought conditions threaten the survival of plant communities, especially in more arid areas Scientists with the U.S. Department of Agriculture, or USDA, and their partners have determined that water demand by many plant communities can fluctuate in response to water availability, indicating a capacity for resilience even when changing...

How Much Do Plant Leaves Shrink When They Dry Out?
2012-11-20 10:24:48

University of Arizona Leaves shrink when they dry out. What sounds straightforward has far-reaching consequences for scientists studying how ecosystems work or reconstructing past climates, a team of 40 middle school students led by a UA graduate student has discovered. A research team consisting of a University of Arizona graduate student, about 40 middle school students and a UA research lab has undertaken the first systematic study looking at how much plant leaves shrink when they...

Climate Change May Have Positive Impact On Some Desert Plants
2012-10-10 09:15:25

Some plants in arid regions benefit from climate change Dryland ecosystems cover 41% of the Earth´s land surface. These ecosystems are highly vulnerable to global environmental change and desertification. But climate change seems to have a positive impact on some plants. A study involving the Max Planck Institute for Demographic Research in Rostock has come to this conclusion. Using demographic methods, ecologist Roberto Salguero-Gómez investigates desert plants to...

Plant Diversity Key To Maintaining Productive Vegetation
2012-05-04 04:01:35

Long-term study finds that each species plays a role in maintaining a productive ecosystem Vegetation, such as a patch of prairie or a forest stand, is more productive in the long run when more plant species are present, results of a new study show. The long-term study of plant biodiversity found that each species plays a role in maintaining a productive ecosystem, especially when a long time horizon is considered. The research found that every additional species in a plot...

Unprecedented long-term study conducted over 14-year period at U's Cedar Creek Ecosystem Science Reserve Vegetation, such as a patch of prairie or a forest stand, is more productive in the long run when more plant species are present, a new University of Minnesota study shows. The unprecedented long-term study of plant biodiversity found that each species plays a role in maintaining a productive ecosystem, especially when a long time horizon is considered. The study found that every...

Image 1 - Out Of Africa And Into The American Midwest

Last of the oak savannas survives at NSF Cedar Creek Long-Term Ecological Research site Grasses bend in the wind, their golden tips tracing arcs across fields that stretch toward the horizon. Sunwashed by a fading evening light, these reedy ballet dancers are central figures in savanna, an ecosystem that covers some 20 percent of Earth's land area. The largest savanna--or grassland with widely spaced trees--is in Africa. But the American Midwest is half a planet away from the...

Image 1 - Climate Change Could Create Big Ecosystem Changes
2011-12-15 04:37:38

By 2100, global climate change will modify plant communities covering almost half of Earth's land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another, according to a new NASA and university computer modeling study. Researchers from NASA's Jet Propulsion Laboratory and the California Institute of Technology in Pasadena, Calif., investigated how Earth's plant life...

Taiga
2013-04-19 18:21:46

Taiga, or otherwise known as boreal forest, is a biome that is characterized by coniferous forests made up mostly of spruces, larches, and pines. The taiga is the world’s largest terrestrial biome. In North America, it covers most of inland Canada and Alaska as well as portions of the extreme northern continental United States and is known as the Northwoods. It covers most of Sweden, Finland, much of Norway, lowland/coastal areas of Iceland, much of Russia, northern Kazakhstan, northern...

Kazakh Uplands
2013-04-18 23:02:25

The Kazakh Uplands, known also as the Kazakh Hummocks, is a large peneplain formation that stretches throughout the central and eastern regions of Kazakhstan. It’s made up of low mountain oases and elevated plains, and contains large deposits of coal within the north and copper within the south. Rare species, such as the Asiatic Cheetah, may still reside in this region. Several notable cities, including the country’s capital, Astana, are located there. A portion of the Kazakh Uplands...

Oceania is one of Earth's eight ecozones. It is the smallest ecosystem found on the planet. Oceania is unique as it is the only ecosystem that does not include any continental land mass. This bioregion includes the Pacific Ocean islands of Micronesia, Fijian Islands, and most of Polynesia (except for New Zealand). This is also the youngest ecozone. While the other ecozones include fragments of ancient continents and land masses, Oceania is composed of volcanic islands and coral atolls that...
