and technological substitutes affect the value of pest control services provided by Mexican free-tailed bats on cotton production in the U s. They found the services are impacted by the forces to the tune of millions of dollars.
Taking into account a drop in cotton commodity price the resulting decrease in cotton production and the adoption of transgenic Bt (Bacillus thuringiensis cotton which is modified to express its own pesticide the researchers found that the value of the pest control services dropped 79 percent from a high of $23. 96 million in 1990
to a low of $4. 88 million in 2008. The results of this study document that volatile market conditions
and technological substitutes such as Bt cotton can affect the value of an ecosystem service even
The researchers point to mounting evidence of the evolution of pest resistance to Bt cotton suggesting that the value of bat pest control services may increase again.
This evidence of resistance evolution suggests that Bt cotton may not be a long-term solution to pest-related losses said Mccracken.
In fact by preying on the individual insects that survive the Bt toxin bats may provide the additional service of slowing the evolution of resistance to Bt and other insecticides.

Promising future for cotton in Cameroon? While climate change threatens most crops in Africa its impact could be less on cotton cultivation in Cameroon.
A new study by researchers from IRD and its partners shows that the expected climate change over the coming decades should not have a negative effect on Cameroonian plantations.
whom cotton is the leading cash crop and often the only alternative. Improved yieldfrom observations made in stations
and plots from 2001 to 2005 and in 2010 in North Cameroon the research team simulated the impact of climate forecasts for the next 40 years on the growth of cotton plants.
Firstly how the cotton is grown is crucial. Field productivity is highly dependent on local farming practices.
Cotton belongs to a type of plant for which CO2 in the atmosphere stimulates photosynthesis (like soya peanuts
The annual yield from cotton fields in Cameroon could increase by around 30 kg per hectare.
The importance of a season of regular rainthe effect of rainfall change on cotton yield also differs from that of crops such as maize sorghum and millet.
In particular excess water threatens cotton with increased runoff leaching of soil and inputs needed for cotton cultivation.
In addition more than the total rainfall the start date and duration of the rainy season are paramount.
A previous study has shown that these two parameters can be used to predict annual cotton yields.
An insurance system with a compensation level based on these rain indices could consolidate the positive outlook for the Cameroon cotton sector by limiting the debt of the poorest producers.
stronger cotton fiberan international collaboration with strong Aggie ties has figured out how to make a longer cotton fiber â#information that a Texas A&m University biologist believes could potentially have a multi-billion
-dollar impact on the global cotton industry and help cotton farmers fend off increasing competition from synthetic fibers.
The research funded primarily by the U s. Department of agriculture Office of International Research Programs is published in the most recent edition of the journal Nature Communications. â#oethis technology allows improvement of fiber quality in upland cotton
which is grown widely everywhereâ#said Alan Pepper an associate professor in the Texas A&m Department of biology and senior author of the paper that was led by a former Texas A&m graduate student now in Uzbekistan. â#oethis will increase the competitiveness of natural cotton fibers versus synthetic fibers
which have been snagging an increasing amount of the market share every year. â#The overwhelming majority of cotton harvested in the U s
. and worldwide is upland cotton or Gossypium hirsutum with more than 6. 5 million acres planted in 2012 in Texas alone according to the USDA.
A higher-end cotton called Gossypium barbadense is more desirable because of greater fiber length and strength but is late-maturing low-yielding
and more difficult to grow because it requires dry climates with significant irrigation and is less resistant to pathogens
and pests. â#oefor a long time cotton breeders have been trying to develop upland cotton with the fiber qualities of barbadense cottonâ#Pepper said. â#oeglobally everybodyâ##s trying to do it.
Economically itâ##s a huge deal because every millimeter you add to fiber length adds that much to the price of cotton
when the farmer sells it. â#The researchersâ##method increased the length of the fiber by at least 5 millimeters
since 1995 acknowledges that the cotton plants developed in the project technically are modified genetically organisms (GMOS) a controversial subject.
For instance the agricultural giant Monsanto adds a gene to cotton that makes it resistant to Roundupâ
The researchers found literature from the 1990s that suggested the amount of red light also influenced fiber length in cotton plants.
The landlocked agricultural nation that borders Afghanistan historically has relied heavily on cotton to strengthen its rapidly diversifying economy.
Once used by the former Soviet union as a base for its cotton production Uzbekistan currently accounts for around 10 percent of world cotton fiber exports. â#oesustainability
and biosecurity of cotton production is pivotal for the Uzbekistan economy because agriculture accounts for 24-to-28 percent of the countryâ##s gross domestic productâ#said Abdurakhmonov who also serves as director of the Center of Genomics and Bioinformatics at the Academy of Sciences of Uzbekistan
New markets for longer finer stronger and more uniform cotton lint fiber as well as early maturity and increased yield potential could further increase estimated economic value.

and shrubs in Concord in the 1850s then repeated his observations over the past five springs.
if all trees and shrubs in Concord are equally responsive to warming temperatures in the spring Polgar said.
Since leafing-out requirements are thought to be species-specific the group designed a lab experiment to test the responsiveness of 50 tree and shrub species in Concord to warming temperatures in the late winter and early spring.
We found compelling evidence that invasive shrubs such as Japanese barberry are ready to leaf out quickly once they are exposed to warm temperatures in the lab even in the middle of winter
whereas native shrubs like highbush bluberry and native trees like red maple need to go through a longer winter chilling period before they can leaf out
However the experiments show that as spring weather continues to warm it will be the invasive shrubs that will be best able to take advantage of the changing conditions.
and in coming decades nonnative invasive shrubs are positioned to win the gamble on warming temperature Primack said.
and the addition of makeshift perches such as transmission polls in sagebrush ecosystems are creating preferred habitat for common ravens that threaten sensitive native bird species including greater sage grouse.
The authors looked at 82 raven nests on the U s. Department of energy's Idaho National Laboratory land in southeastern Idaho a sagebrush steppe ecosystem where ravens increased in numbers eleven-fold between 1985 and 2009.
Nesting on the poles may also gain them greater security from predators range fires and heat stress.
In addition to proximity to transmission lines ravens in the study area selected nest sites that were in close proximity to edges formed between sagebrush
The scientists believe that in contrast to continuous sagebrush stands edges enable the ravens to more readily detect prey
The results of these findings pointed to further increases in raven abundance in formerly natural sagebrush steppe following alterations made by people specifically those associated with energy development and an expanding electric grid.
The authors state Such an increase likely poses an increased threat to sagebrush steppe species subject to raven depredation including sage-grouse for
