Ecology in agricultural landscapes: Seeking solutions for food, water, wildlife

A compendium of agro-ecology sessions at the 2013 annual meeting of the Ecological Society of America

2013-07-25

(Press-News.org) Agriculture alters the landscape more than any other human activity, with trickle-down effects on water, soil, climate, plant and wildlife diversity, wildfire, and human health. Crop and rangeland occupies nearly 40 percent of earth's ice-free land, and mountains and deserts make much of the remaining surface unwelcoming to agriculture. Our increasing population applies constant pressure for further conversion of wild lands to agricultural production. With yields plateauing in many parts of the world, managers, both private and public, are looking for new ideas to get the most out of agricultural lands, sustain production into the future, and protect natural resources.

Multiple sessions will address the ecological study of agricultural systems at the Ecological Society of America's 98th Annual Meeting in Minneapolis, Minnesota, August 4 – 9.

Presenting scientists will examine routes to improved soil, water, and nutrient retention, pollinator support, and pest suppression by natural enemies. They will discuss opportunities to increase biodiversity in agricultural areas and mitigate runoff.

Land sharing

Organized Oral Session 23: Bridging The Public-Private Land Divide - Supporting Biodiversity Conservation and Ecosystem Services By Tapping The Ingenuity In Social-Ecological Systems.

Thursday, August 8, 2013: 8:00 AM-11:30 AM, room 101A

For much of the world, high-intensity industrial farming produces food with high efficiency, but puts the squeeze on other plant and animal life. Wildlife is mostly sequestered on preserves. But is this the best way to maximize food and biodiversity? Or are there other configurations that might improve mobility of wildlife and benefit other ecosystem services without cost (and possibly with benefit) to private land owners?

"We are probably not going to be able to achieve landscape conservation goals for soil, water, and wildlife, specifically grasslands and birds, working on publically-owned lands alone. We will need to incorporate private lands," said session moderator Chris Woodson, a private lands biologist with the U.S. Fish and Wildlife Service in Missouri. Conservation biologists are looking for conservation-supportive practices that have potential to augment protected areas on public lands and aid existing programs. Private landowners and entrepreneurs are looking for contributions that they can make to conservation and still make a living.

This session brings together managers, scientists, private land owners, and entrepreneurs to discuss ideas, pilot projects, and existing public-private partnerships, and seek areas of mission overlap and opportunities for collective action.

"Lower case c conservation is what we want to see happen," said session co-organizer Paul Charland, a wildland firefighter with the U. S. Fish and Wildlife Service. "Capital C Conservation is official business; it's the movement as an organizational process. Lower case conservation is all efforts to keep native species. We want to provide a mechanism for everyone to do that."

Connecting the global to the local – agricultural landscapes from field to orbit

Symposium 20: Integrating Agro-Ecological Research Across Spatial and Temporal Scales

Thursday, August 8, 2013: 1:30 PM-5:00 PM

Big changes in agriculture are visible on the global scale – changes in crop yields, dietary choices, water use, fertilizer application, soil retention, and nutrient pollution. In some parts of the world, yield lags, revealing opportunities to get more out of land already in production. In others, crop production has sagged or plateaued. Will yields keep increasing as they have in the past? It's hard to see trajectories without local context, said session organizer Kate Brauman of the University of Minnesota's Institute on the Environment. Site-specific field work fills in details.

"Agronomy has been working very successfully for a long time, and it's been focused on practitioners," said Brauman. "And global analysis can be hard for someone in the field to interpret. How can we take insights from the local to the global scale and make them useful?" Ecology has great scientists studying the very local, applied art and science of getting more yield out of our crops and the local ecological effects of agriculture, and great scientists studying global trends, said Bauman. It does not have much of a history of cross-pollination between the groups. This session aims to bridge gulfs of scientific culture and of scale, connecting the satellite's eye view of global change to the view from the field; computational modeling to on-the-ground experimentation; and snapshot observations to daily, seasonal, annual, and decadal change.

Organizer: Kate Brauman

Stopping cholesterol drugs may be associated with increased risk of Parkinson's

2013-07-25

MINNEAPOLIS – People who stop taking cholesterol drugs may be at an increased risk for developing Parkinson's disease, according to research that appears in the July 24, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Previous studies on the relationship between cholesterol drugs called statins and the risk of Parkinson's disease have had inconsistent results. The current study involved 43,810 people in Taiwan who were taking statins and did not have Parkinson's disease. Taiwan's compulsory national health insurance program ...

Rules of attraction: Catching a peahen's eye

2013-07-25

Getting the undivided attention of a female is tough at the best of times but it's even harder when surrounded by other male suitors. It's no wonder males often resort to ostentatious displays to distinguish themselves from the crowd, and nowhere is this clearer than in peacocks. Sexual selection has driven the evolution of their showy iridescent trains, whose main purpose is to attract females. But what is it about this train of colourful feathers that attracts peahens? Is it the characteristic eyespots or perhaps the green scale-like feathers? Researchers have tried to ...

Brain research shows psychopathic criminals do not lack empathy, but fail to use it automatically

2013-07-25

Criminal psychopathy can be both repulsive and fascinating, as illustrated by the vast number of books and movies inspired by this topic. Offenders diagnosed with psychopathy pose a significant threat to society, because they are more likely to harm other individuals and to do so again after being released. A brain imaging study in the Netherlands shows individuals with psychopathy have reduced empathy while witnessing the pains of others. When asked to empathize, however, they can activate their empathy. This could explain why psychopathic individuals can be callous and ...

'Weightism' increases risk for becoming, staying obese

2013-07-25

Weight discrimination may increase risk for obesity rather than motivating individuals to lose weight, according to research published July 24 in the open access journal PLOS ONE by Angelina Sutin and Antonio Terracciano from the Florida State University College of Medicine. The researchers compared the height and weight of over 6000 participants, measured in 2006 and 2010. They found that participants who experienced weight discrimination earlier were 2.5 times more likely to become obese by the follow-up assessment in 2010. Obese participants who perceived weight discrimination ...

Laser-controlled molecular switch turns blood clotting on, off on command

2013-07-25

Researchers have designed tiny, light-controlled gold particles that can release DNA controls to switch blood clotting off and on. The results are reported July 24 in the open access journal PLOS ONE by Kimberly Hamad-Schifferli and colleagues from the Massachusetts Institute of Technology. The two-way switch for blood clotting relies on the ability of two gold nanoparticles to selectively release different DNA molecules from their surface under different wavelengths of laser excitation. When stimulated by one wavelength, one nanorod releases a piece of DNA that binds ...

Professionals often attribute applicants' success to personal traits, not circumstance

2013-07-25

Professionals evaluating graduate school or job applicants frequently attribute applicants' credentials to their personal qualities rather than their circumstances, according to research published July 24 in the open access journal PLOS ONE by Samuel Swift from the University of California, Berkeley and colleagues from other institutions. Higher grading schools and work environments that make it easier to succeed can play a significant role in inflating applicants' qualifications. In this study, participants were presented fictitious examples of graduate school applicants ...

Speaker's power to act on words influences listeners' brain response

2013-07-25

A speaker's power to act on his words influences how a listener perceives the meaning of their message, according to research published July 24 in the open access journal PLOS ONE by Ina Bornkessel-Schlesewsky from the University of Marburg, Germany, and colleagues from other institutions. For example, listeners are more likely to believe a political figure is capable of acting on the words "Tear down this wall!" than when an ordinary citizen makes the same statement. In this study, researchers presented participants with videotaped statements about politics spoken by ...

Common agricultural chemicals shown to impair honey bees' health

2013-07-25

COLLEGE PARK, Md - Commercial honey bees used to pollinate crops are exposed to a wide variety of agricultural chemicals, including common fungicides which impair the bees' ability to fight off a potentially lethal parasite, according to a new study by researchers at the University of Maryland and the U.S. Department of Agriculture. The study, published July 24 in the online journal PLOS ONE, is the first analysis of real-world conditions encountered by honey bees as their hives pollinate a wide range of crops, from apples to watermelons. The researchers collected ...

Johns Hopkins researchers reveal genetic glitch at the root of allergies

2013-07-25

Newly published research by investigators at Johns Hopkins Children's Center and the Johns Hopkins Institute of Genetic Medicine reveals that a faulty genetic pathway already known for its role in some connective tissue disorders is also a potent player in many types of allergies. Scientists have long understood that allergies are the result of a complex interplay between environment and genes, but now, in what investigators believe is a scientific first, a single genetic pathway has been implicated in an array of allergic disorders. A report on the study's findings, ...

Genome mapping of oil palm poised to improve yields, protect rainforest

2013-07-25

The identification of a single gene critical for yield of the oil palm, a crop that accounts for nearly half of world-wide edible vegetable oil, is reported along with the plant's genomic sequence in a set of papers published online July 24, 2013 ahead of print in Nature. The findings have implications for enhancing the future production and sustainability of palm oil, including a reduction in the pressure this productive tropical crop exerts on the footprint of wild rainforests. The work was authored by investigators from the Malaysian Palm Oil Board (MPOB) and Orion Genomics. "Our ...
