Brazils Pantanal, a vast wetland situated in the center of South America, has become the next frontier for leading-edge eco-tourists in search of ever more exotic flora and fauna. "Its where people go after theyve been to Africa," says Shannon Bouton, a Ph.D. student in the School of Natural Resources and Environment (SNRE) at the University of Michigan.
This month, Bouton is publishing the results of her unique study of a wading bird colony in the Pantanal in the February issue of Conservation Biology, the journal of the Society for Conservation Biology. The article, co-authored with Peter C. Frederick (University of Florida), is titled "Stakeholders Perceptions of a Wading Bird Colony as a Community Resource in the Brazilian Pantanal." Unlike other research projects that consider only the biological effects of tourism, Bouton has combined her biological research with a study of how the colony serves as a resource for the local community. Her practical suggestions for meeting the twin goals of managing and developing tourism and conserving the colony have attracted the attention of top government officials and diplomats in Brazil and have made her study site at Porto da Fazenda a model for similar efforts in the region.
Today, as a result of those suggestions, local forestry police have posted a guard in front of the colony to control the behavior of tourists and fishermen. A local conservation group, Associação Ecológica Melgassense (AMEC) has established a staffed observation post that is occupied year-round to protect the birds and the forest. AMEC trains young people from the community as guides to take tourists along newly constructed trails at a safe distance from the colony and runs workshops for local children and adults so that everyone is aware of the biology of the birds, their importance to the community and how to behave so as not to disturb them.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
