Overcoming obstacles to measure nitrous oxide emissions

Fri, 22 Sep 2017 00:00:00 EDT

(American Society of Agronomy) 'Indirect' emissions of nitrous oxide (N2O) represent a large and very uncertain component of the greenhouse gas budget of agricultural cropping systems, but quantifying and reducing indirect N2O emissions have proven to be very challenging. The symposium, 'How Can We Improve Our Estimates of Indirect N2O Emissions,' planned at the Managing Global Resources for a Secure Future ASA, CSSA, SSSA International Annual Meeting in Tampa, FL, will address this important topic.



Development of an artificial orchid cultivation kit

Thu, 21 Sep 2017 00:00:00 EDT

(Kumamoto University) Orchids are loved by gardeners around the world but are notoriously difficult to cultivate. Researchers have developed a new orchid cultivation kit and have succeeded in complete artificial cultivation of an autonomous orchid. Since this kit can be made cheaply, it can broaden the opportunities for orchid cultivation in general households. It is also expected to be useful in preserving the genetic diversity of orchidaceous plants, many of which are in danger of extinction.

UM Rosenstiel School was the only research institution to receive two of the eight highly competitive research consortia grants awarded by GoMRI in its final two-year funding cycle.



Understanding the dance to save the dance

Thu, 21 Sep 2017 00:00:00 EDT

(Botanical Society of America) Plant-pollinator relationships are vital to our natural and agricultural ecosystems, with an incredible amount of food crops worldwide dependent on plant-pollinator interaction success. But the advancement of climate change is disrupting plant-pollinator relationships. A special issue of Applications in Plant Sciences -- Studying Plant-Pollinator Interactions Facing Climate Change and Changing Environments -- explores the creative methods being used by researchers to study the effects of climate change on plant-pollinator relationships.



Ozark grasslands experience major increase in trees and shrubs

Thu, 21 Sep 2017 00:00:00 EDT

(University of California - Davis) Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study published this week in the journal Landscape Ecology. If these ecosystems continue to favor woody vegetation, will it be possible to maintain open grasslands for the foreseeable future?



Scientists and farmers work together to wipe out African lovegrass

Thu, 21 Sep 2017 00:00:00 EDT

(Queensland University of Technology) A partnership between QUT, the NSW Government and farmers could lead to the eventual eradication of the highly invasive African lovegrass threatening pastures and native grasslands Australia-wide.What they discovered is that local knowledge is the key to a successful management approach.



Whole food diet may help prevent colon cancer, other chronic conditions

Thu, 21 Sep 2017 00:00:00 EDT

(Penn State) A diet that includes plenty of colorful vegetables and fruits may contain compounds that can stop colon cancer and inflammatory bowel diseases in pigs, according to an international team of researchers. Understanding how these compounds work on a molecular level could be an initial step toward finding treatments for people with cancer, they added.



Researchers discover new cattle disease and prevent it from spreading

Thu, 21 Sep 2017 00:00:00 EDT

(University of Copenhagen The Faculty of Health and Medical Sciences) Following genetic studies of deformed calves research conducted at the University of Copenhagen is able to uncover a hitherto unknown disease found among Holstein cattle. The breeding bull from which the mutation and thus the deformation originate has now been put down to prevent the disease from spreading further.



Changing of the guard -- research sheds light on how plants breathe

Thu, 21 Sep 2017 00:00:00 EDT

(John Innes Centre) New research is set to change the textbook understanding of how plants breathe.



Lightning-fast trappers

Thu, 21 Sep 2017 00:00:00 EDT

(University of Freiburg) New findings on the biomechanics and evolution of suction traps in carnivorous bladderworts.



Going diving in the tropics? Don't eat the reef fish!

Thu, 21 Sep 2017 00:00:00 EDT

(University of British Columbia) Reducing tourist consumption of reef fish is critical for Palau's ocean sustainability, finds a new UBC study that suggests other small island nations might also consider adopting this strategy.



Signs of sleep seen in jellyfish

Thu, 21 Sep 2017 00:00:00 EDT

(Howard Hughes Medical Institute) The upside-down jellyfish Cassiopea demonstrates the three hallmarks of sleep and represents the first example of sleep in animals without a brain, HHMI researchers report.



The surprising, ancient behavior of jellyfish

Thu, 21 Sep 2017 00:00:00 EDT

(California Institute of Technology) The discovery that primitive jellyfish sleep suggests that sleep is an ancient, evolutionarily conserved behavior.

Palau ocean sustainability linked to tourist consumption of reef fish

Wed, 20 Sep 2017 00:00:00 EDT

(Nippon Foundation-Nereus Program) Reducing tourist consumption of reef fish is critical for Palau's ocean sustainability, finds a new Nippon Foundation-UBC Nereus Program study published today in Marine Policy. While climate change is expected to lead to sharp declines in Palau's reefs, the best tourism management strategy includes a more than 70 per cent reduction in reef fish consumption by visitors. These findings are highly relevant for sustainable development in small island developing states under climate change.
