To have the vegetation of a habitat preserved right along with the fossil primates themselves isn't a regular occurrence in primate paleontology she said.
The green-up indicated productive thriving vegetation in spite of limited rainfall. Now a new NASA study published today in the journal Nature shows that the appearance of canopy greening is caused not by a biophysical change in Amazon forests
Scientists who use satellite observations to study changes in Earth's vegetation need to account for seasonal differences in the angles of solar illumination
An area is covered likely in green vegetation if sensors detect a relatively small amount of red light--absorbed in abundance by plants for photosynthesis
Scientists use the ratio of red and near-infrared light as a measure of vegetation greenness.
At this point the forest canopy is shadow-free highly reflective in the infrared and therefore very green according to some satellite vegetation indices.
and to explore the influence of drought on corrected vegetation indices said Scott Goetz an ecologist at Woods Hole Research center in Woods Hole Mass. who was not involved with the Nature study.
This interdisciplinary collaboration is critical to improve our understanding of the patterns and processes driving changes in vegetation productivity.
Terrestrial vegetation naturally emits vast quantities of volatile organic compounds for instance. These are critical precursors for organic aerosols and ozone a potent greenhouse gas.
According to their findings the increase in global vegetation was the dominant driver of emissions during the Pliocene--and the subsequent effects on climate.
The team used a high-resolution data set of vegetation carbon stock (VCS) to map 16257 corridors through areas of the highest biomass between 5600 protected areas in the tropics.
#Three native aromatics indicated for use in Mediterranean extensive green roofsgreen roofs are being studied as a means to increase vegetation and preserve aesthetics in old Mediterranean cities.
These planners argued that public spaces with large amounts of vegetation were essential elements of healthy functional cities.
and other vegetation that characterize these spaces are important for meeting the community and ecosystem needs of low income urban neighborhoods that do not have large expanses of undeveloped land
#Savanna vegetation predictions best done by continenta one-size-fits-all model to predict the effects of climate change on savanna vegetation isn't as effective as examining individual savannas by continent according to research published in Science this week.
We wanted to find out what controls savanna vegetation--essentially the density of trees within the savanna
#Integrating vegetation into sustainable transportation planning may benefit public healthstrategic placement of trees and plants near busy roadways may enhance air quality and positively impact public health.
A multidisciplinary group of researchers planners and policymakers recently gathered in Sacramento Calif. to discuss roadside vegetation as a viable option for mitigating these adverse health impacts from air pollution.
The group agreed that vegetation barriers are a form of green infrastructure that can provide environmental economic and social benefits to their surrounding areas.
Properly designed and managed roadside vegetation can help us breathe a little easier said Dr. Greg Mcpherson research forester at the U s. Forest Service's Pacific Southwest Research Station.
A major analysis of vegetation histories across the three islands and the SE Asian mainland has revealed a pattern of repeated disturbance of vegetation since the end of the last ice age approximately 11000 years ago.
Our findings however indicate a history of disturbances to vegetation. While it could be tempting to blame these disturbances on climate change that is not the case as they do not coincide with any known periods of climate change.
Rather these vegetation changes have been brought about by the actions of people. There is evidence that humans in the Kelabit Highlands of Borneo burned fires to clear the land for planting food-bearing plants.
This indicates that the people who inhabited the land intentionally cleared it of forest vegetation and planted sources of food in its place.
or rainforests as the historical role of people in managing the forest vegetation has rarely been considered.
vegetation in half. Such land transformations while necessary to ensure future crop productivity can themselves have large ecological impacts
However the findings in the study indicated that ravens also preferred nesting areas with nonnative vegetation
as a result of grid development and that protecting unaltered landscapes from fragmentation by transmission lines roads crested wheatgrass plantings and the invasion of other nonnative vegetation is integral to stemming range expansion by ravens.
and effect on understory vegetation over time are understood not well but such information is useful to forest management focused on restoring biodiversity and resilience to these ecosystems.
and understory vegetation (tree seedlings shrubs and herbaceous species) was quantified within quadrats in the old-growth condition in 1929 prior to logging later in 1929 after logging and again in 2007 or 2008.
Change to non-tree vegetation was pronounced most for shrub cover which averaged 28.6%in 1929 but only 2. 5%in 2008.
Understory vegetation should benefit from thinning or prescribed fire treatments that lead to a greater abundance of higher light environments within stands.
the sheep could prove extremely useful in making sure vegetation doesn â¢t grow into habitats for birds
and anywhere else with overgrown vegetation. When they become too old to work these goats are sold not for meat!
In habitats where there is lots of natural vegetation, there are many organisms making vocalizations. As you look at areas that are disturbed more
and in line with many new housing and community developments and vertical gardens around the world, vegetation assume a major role in the design,
Clearing forests of their underbrush, dead trees, logging remnants and fallen branches might also affect soil health, biodiversity and wildlife habitat.
the site had become overgrown with vegetation after years of disuse. Trees flourished where there were once mounds of sand to put out any accidental fires.
to measure global topography, vegetation, the mass of ice sheets and the height of aersols and clouds.
