and at great cost by eliminating some of the trial and error in identifying new sites on proteins that could be manipulated more easily to treat disease said Rice biological physicist Jos Onuchic.
when it comes to choosing the best site for egg-laying. Using behavioural assays researchers at the Max Planck Institute for Chemical Ecology in Jena Germany
For egg-laying insects selecting the best site to lay eggs is crucial for the survival of the eggs and larvae.
It is fascinating that a complex behaviour such as choosing an egg-laying site can be broken down into multiple subroutines that have such a simple genetic basis says Marcus Stensmyr.#
What we are seeing is a consistent habitual use of caves as sleeping sites by these primates a wonderful behavioral adaptation we had known not about before.
But in spiny forests most of the trees with woody stems are covered in rows of spines making them uncomfortable as well as dangerous sleeping sites
Rohani and colleagues say that such a phenomenon has recently been observed in controlled badger culls in the United kingdom where disruption of badger social dynamics and subsequent dispersal led to increased tuberculosis transmission in cattle at neighboring sites.

if the relationship between density and mortality varies with site quality as ponderosa pine stands developed.
and Analysis group these researchers found that site quality affected the relationship between density and mortality.
The research also confirmed the added value of such long-term study sites which allow new questions to be addressed that were included not in the original studies.

Pioneering excavations within the sacred Maya Devi Temple at Lumbini Nepal a UNESCO World Heritage site long identified as the birthplace of The buddha uncovered the remains of a previously unknown sixth-century B c. timber structure
and strengthened site management to ensure Lumbini's protection. These discoveries are very important to better understand the birthplace of The buddha said Ram Kumar Shrestha Nepal's minister of culture tourism and civil aviation.
The government of Nepal will spare no effort to preserve this significant site. Buddhist tradition records that Queen Maya Devi the mother of The buddha gave birth to him

The pillar which still stands bears an inscription documenting a visit by Emperor Asoka to the site of The buddha's birth as well as the site's name--Lumbini.
Returning to the same grass-invaded field sites in Hawaii volcanoes national park that she used in her 1990-1995 studies D'Antonio
We permanently marked sites we had set up and were able to go back and gain insight into how plant invasions changed over time without management said D'Antonio who also is a professor in the Department of Ecology Evolution and Marine Biology.
When D'Antonio and Yelenik revisited the study sites they noticed that the invasive exotic perennial grasses (primarily an African invader called Melinis minutiflora) were dying so they decided to repeat measures of nutrient cycling and plant community change.
Data showed that in the past 17 years nitrogen mineralization rates at the sites dominated by the exotic grasses declined by half returning them to pre-invasion levels.
Plus in our sites it is dispersed bird which means it gets around and is in fact moving into the sites at a frightening rate.
By contrast the native Acacia did reasonably well in the experiment but it just does not have as robust a growth rate as Morella.

The research team conducted a synthesis of data collected from more than 600 secondary forest sites from 74 previous studies describing carbon pools
Each site had comparable data for a nearby site that was relatively free of human disturbance.
Their results suggest that trees at drier sites buy insurance for their leaves in the form of beefed-up ant protection
and Azteca ants (Azteca pittieri) Pringle and her colleagues studied the interaction at 26 sites in seasonally dry tropical forests along the Pacific coast of southern Mexico and Central America.
The coastal sites span 1426 miles with annual precipitation increasing fourfold from the northernmost to the southernmost site.
and defense of leaves by ants--was greater at sites with longer dry seasons. Laurel trees don't feed ants sugar directly.
Pringle and her colleagues found that at the drier study sites laurel trees support more scale insects which in turn produce more honeydew.
Defoliation is a greater potential threat at the drier sites because laurels there have smaller carbon reserves
The fact that laurel trees at drier sites pay their ant protectors higher wages suggests that the potential costs of defoliation outweigh the relatively modest price of supporting more ants.
which ants protect trees from rare but life-threatening defoliation events best fit observations from the 26 sites.
Like farmers buying crop insurance the trees at drier sites appear to be hedging their bets:
The observed differences between dry and wet sites may therefore reflect genetic adaptations to local conditions the researchers suggest.
We were surprised completely to see so many bay cats at these sites in Borneo where natural forests have been logged so heavily for the timber trade.
Given the concentration of pig bones found at Philistine archaeological sites the European pigs likely came over in the Philistines'boats.
Pig bones have been found in abundance at Philistine archaeological sites along Israel's southern coastal plane dating from the beginning of the Iron age around 1150 to 950 BCE.
or absent at Iron age sites in other parts of the country including in the central hills where Ancient Israel is thought to have emerged.

For the study Fierer an associate professor of microbial ecology and his colleagues used samples of soil collected from 31 different sites spread out across the prairie's historical range.
It was very hard to find sites that we knew had never been tilled Fierer said.
because this is such a highly invaded site she says. Most of this soil has been processed by earthworms.
Since we can grow it in much closer proximity to our production sites we can further reduce both the environmental impact as well as our logistics costs by a substantial margin.
Dr. Dirk Prã fer describes the research efforts at the MÃ nster-based IME site.
Half were planted at sites north of the A. picea/A. rudis boundary and half south of that boundary.
At both sites the later-blooming A. arifolium offspring were dispersed in a manner that suggested that ants picked up its seeds.

Pollination success of generalist plants tends to be positively related to pollinator diversity so any habitat modifications that increase the number of pollinating species present at a site would tend to be of some inherent value.
The situations described above give the impression that the presence of some exotic flowering plants may be of benefit by encouraging higher numbers of pollinating species to occur at a site.

Kerby added that archeological evidence suggests that caribou have used this area as a calving site for over 3000 years.
In addition to analyzing their own data Post and Kerby also used information from a 1970s study of caribou calving and calf survival at the same site by Danish biologists Henning Thing and Bjarne Clausen.
Impurities and defects on the dust grains produce catalytic sites for the formation of hydrogen molecules which are ejected subsequently creating miniature rocket engines also called Purcell thrusters after Nobel laureate Edwin Purcell who studied grain alignment.
It seems that especially temperature reconstructions derived from extreme sites such as high mountain zones and high latitudes do not always correctly reflect the climate of the different geographical regions.

'Only by viewing forest sites along a gradient of logging disturbance ranging from pristine to heavily degraded were the team able to detect a gradual decline of some key bat species. The research confirmed the most vulnerable bats were those that tend to live in the cavities of old growth trees.
By linking bat captures with vegetation measurements from nearby plots the researchers were able to reveal how these animals declined as successive rounds of logging took their toll on forest structure and crucially the availability of tree cavities.
--or at any rate they gather up the bacteria carry them to new sites and harvest them prudently.
Farmers save roughly half the bacteria available to them forgoing considerable food to save some for dispersal at a new site.

By moving away from freshly damaged sites they can minimize risk of predation and avoid competition explained Prof.
because the climate has shifted to become suitable for another set of species. This also makes it challenging to adhere to a management plan granting preservation status to a particular type of nature at a certain site.
At such a site the existence of a large number of fully grown specimens of an endangered species is no guarantee that there will be a next generation.
If it were to migrate unaided from its nearest native site in Southeast europe to Denmark it would take thousands of years.
This will make post-fire recovery on dry sites slow and uncertain. If forests are desired in these locations more aggressive attempts at reforestation may be needed they said.
A decade after this fire there was almost no tree regeneration at lower drier sites said Erich Dodson a researcher with the OSU Department of Forest Ecosystems and Society.
There was some regeneration at higher sites with more moisture. But at the low elevations it will be a long time before a forest comes back
These dry sites with less resilience to stand-replacing fire should be priorities for treatment
