Bat diet :Throughout the evening, bats hang on our landscape consuming insects, but they do it in secret, hidden from our view. Until recently, scientists have been able to bring its ecosystem of darkness, but thanks to new genetic techniques bat diet, researchers at the University of Bristol and the Biodiversity Institute of Ontario Canada, were able to reconstruct the environment to support these elusive creatures.
Working in three sites in southern Ontario (Canada), the team of students and scientists monitored the diet of little brown bat (Mortis launchings) colonies bat diet living on agricultural land and a conservation. Guano (bat droppings) were collected continuously in every house from May to August
Back bat diet in the laboratory of the Biodiversity Institute of Ontario, Canada, the team extracted DNA from insects of the material and sequenced a "barcode DNA," which is a small region of DNA that can be used to identify species. The team then adapted these unknown sequences in bat guano in a bank of known sequences to identify bats insect prey insects to eat bat diet.
"This technology is very new," says bat diet lead author Dr Elizabeth Clare, School of Biological Sciences, University of Bristol. "It gives us new information about the behavior of bats. Instead of just finding they ate a butterfly or ephemeral, we now know exactly what kind of insect it was, providing us with important information on their habitat. "
Using this technique, the team discovered that bats rely heavily on aquatic insects. They were also able to identify the exact bat diet species of insect prey, which revealed that different colonies exploit different sources of water, rivers and streams, sometimes it happens that ponds depending on the local landscape.
"Some of the insects they eat come from very specific environments and have specific tolerances for contaminants. These "environmental indicators" allow us to reconstruct exactly what their foraging habitat was similar, "says Dr. Clare." This is bat diet a non-invasive way to monitor its behavior -. A bit like looking through the trash of a person to see where they shop "
Bats ate very local bat diet - traveling a few hundred meters to catch its insect prey. Species that change with the seasons and dietary changes are the stages of pregnancy and lactation in bats.
The researchers bat diet also found that bats in agricultural habitats seem to have a more restricted diet of fewer insect species of bats in a conservation area, even if the source of water in all areas was good quality.
Dr. Clare added: "This suggests that even small conservation projects can have an impact on the entire food chain This site has a small patch of forest, a small pond and a dedicated group of agents conservation it all bat diet .. components seem to have generated a good environment for insects and bats so that they support. "
The results of this research are more important than this kind of bat is seriously threatened by the spread bat diet of a fungal disease called "white nose syndrome", which may endanger the survival of populations of America . Dr. North Clare said: "Understanding how bats exist in the ecosystem is vital to our conservation goals."
