To test this hypothesis graduate student Chia-Ching Chu analyzed the population of microbes living in the guts of rootworm beetles collected from seven sites across the Midwest.
Some of these sites (including Piper City Ill. are hot spots of rotation-resistance and others (in Nebraska and northwest Missouri for example) lack evidence of rotation-resistant rootworms.
Crews that cut down the trees built roads to reach the sites which became avenues for the spread of ailanthus.
The older seed-producing trees were often found upwind from the sites of the recent ailanthus growth.
New roads are being constructed into these active drilling sites said Kasson. These drilling operations could lead to future spread.
The three year study was conducted across nine woodland sites in Cornwall. During winter populations of blue tits were left unfed given plain fat balls
Nest boxes and bird feeders were distributed around the woodland study sites and reproductive success was investigated by checking the nest boxes in the spring to determine the number of eggs laid and the growth and survival of chicks.

Using data from 75 study sites researchers found that high levels of cattle grazing were associated with reduced bunchgrass cover with wider
Impacts are greater on the drier and warmer sites within this region. If the level and amount of gaps indicates that it's necessary changes in grazing could help restore bunchgrass cover maintain a diversity of native grass species
A recent study led by Joseph Ferraro Ph d. assistant professor of anthropology at Baylor offers new insight in this debate with a wealth of archaeological evidence from the two million-year-old site
The research team worked at the site for more than a decade recovering thousands of animal bones and rudimentary stone tools.
These animals are represented well at the site by most or all of their bones from the tops of their head to the tips of their hooves indicating to researchers that they were transported to the site as whole carcasses.
Many of the bones also show evidence of cut marks made when hominins used simple stone tools to remove animal flesh.
The site also contains a large number of isolated heads of wildebeest-sized antelopes. In contrast to small antelope carcasses the heads of these somewhat larger individuals are able to be consumed several days after death
KJS hominins not only scavenged these head remains they also transported them some distance to the archaeological site before breaking them open
and nesting sites are most likely behind bee declines. France has had restrictions of neonicotinoids over the last ten years yet the bees there remain as bad if not worse than they are in the UK.

and wheat were farmed at the site they point to elevated levels of the isotope N15 (nitrogen 15).
and calculate locations of feeding sites communication spots and dens. Pumas communicate with scent markings known as scrapes where they scrape leaves
Researchers also found 10 den sites belonging to 10 different female lions. They visited 224 GPS clusters where activities suggested a feeding site and located prey remains at 115 sites.
Wilmers said the research is helping identify corridors where pumas typically travel between areas of high-quality habitat.
The primary results indicated the family unit had a strong effect on human microbial community composition across all body sites said Knight.

I'm trying to assess sustainable subsistence strategies within the time period of the site Berkebile says.
The MU 125 archaeological site in northern Arizona features a multi-room masonry structure occupied by the ancient Puebloans from 1070-1090.
Berkebile looks for ancient plant remains inside soil samples excavated from the site. She uses a flotation technique to reveal the secrets hidden within the ancient earth.
Berkebile thinks it's likely the Puebloans lived at the MU 125 site year-round and to do so they would have needed to develop sustainable agricultural methods that complemented their maize crops.
She uses the plant samples she's found at the site to assess the Puebloans'agricultural strategy.
#Sensitive sites: Research examines preservation of Southwest archaeology in time of tight budgetswhen surveying in the Upper Basin of the Grand canyon national park in April 2011 University of Cincinnati faculty
However differing policies and fewer available protective resources mean that archaeological sites and finds in Kaibab National park have greater likelihood for destruction.
The forest's environmental and archaeological sites are vulnerable for a number of reasons. These includefor instance Washam's research points to one woodcutting area of the forest that encompassed 30 acres of felled trees in 2006.
Moreover they said that exposure to different combinations of pesticides that act at this site may increase this risk.

and low-income housing sites for the 34 week study. Sixty-three completed the diet protocol and the six-month follow-up requirement.
Many of the sites have long-term monitoring programs and data sets spanning decades and so provide unique opportunities to evaluate long-term trends.
Some sites have over 40 years of weekly data. The researchers analyzed 559 years of stream nitrate and 523 years of stream ammonium data from 22 streams in 7 experimental forests across the country.
They also observed that within a forest trends were not always in sync--at some sites two streams within an experimental forest had opposing trends for the same type of nitrogen for the same period of time suggesting that the controls on stream nitrogen concentrations may vary among and within sites.

The new study showed that pinyon pine seed cone production declined by an average of about 40 percent at nine study sites in New mexico
The biggest declines in pinyon pine seed cone reproduction were at the higher elevation research sites experiencing more dramatic warming relative to lower elevations said Redmond of CU's ecology and evolutionary biology department.
We are finding significant declines in pinyon pine cone production at many of our study sites said Redmond.
Temperature and precipitation were recorded at official long-term weather stations located near each of the nine sites.
For the new study Redmond revisited nine pinyon pine study sites scattered throughout New mexico and Oklahoma that had been studied previously in 1978 by Forcella.
In 2008 Argentine ants had populations in 99 percent of the sites within the study area
while only 9 percent of the sites were home to Asian needle ant populations. By 2011 Argentine ants were found in only 67 percent of the sites
--while the Asian needle ants had expanded to occupy 32 percent of the sites. The two ant species shared 15 percent of the sites in common.
This is the first time we've seen another ant species take territory from Argentine ants says Spicer Rice lead author of a paper on the research.
The researchers think that the Asian needle ant's ability to tolerate cooler temperatures may play a significant role in its ability to push out Argentine ants.

Hundreds of studies over two decades from sites around the world suggest that the Stress Gradient Hypothesis can be employed as a rule of thumb.
However those measurements do not consider the soil properties of individual fields or sites.##oeatmospheric variables do not take into account soil moisture#explains Tyson Ochsner lead author of the study.#
The threshold was determined for each study site since available water a factor used to calculate threshold is affected by specific soil characteristics.#
#oethe soil water contents differ across sites and depths depending on the sand silt and clay contents#says Ochsner.#
#oereadily available water is a site-and depth-specific parameter.##Upon calculating soil water deficits and stress thresholds for the study sites the research team compared their assessment of drought probability to assessments made using atmospheric data.
Camera trap data revealed that lowland tapir abundance was higher at sites under protection than sites outside protected areas.
At one site sampled over time the Tuichi River camera trapping has revealed that lowland tapir populations have been recovering following the creation of Madidi National park in 1995.
The invaded sites can catch up with uninvaded ones Knight adds because the number of species does not increase indefinitely.
At any site if you sample larger and larger areas the number of species will eventually plateau.
At an invaded site you reach that plateau later but you do reach it eventually.
