Human hands leave prominent ecological footprints

Friday, June 1, 2012

Early human activity has left a greater footprint on today's ecosystem than previously thought, say researchers working at the University of Pittsburgh and in the multidisciplinary Long Term Ecological Research (LTER) Network, created by the National Science Foundation to investigate ecological processes over long temporal and broad spatial scales. Highlighted in the June issue of BioScience, the Pitt/LTER collaboration shows how historic human actions caused changes in nature that continue to reverberate throughout present-day ecosystems.

In the article, researchers take a retrospective look at the impact of human activity on LTER Network sites spanning states from Georgia to New Hampshire and propose methods for measuring the effects of such activity. The study of legacy effects is important because it provides insights into how today's actions can affect tomorrow's ecological systems, says Daniel Bain, coprincipal investigator at the Baltimore Ecosystem Study LTER Network site and an assistant professor in the Department of Geology and Planetary Science in Pitt's Kenneth P. Dietrich School of Arts and Sciences. Bain notes that decision makers at all levels, including those creating policy, need historical information about ecosystems to make more effective environmental policies. In a democracy, says Bain, a diverse group of stakeholders?such as outdoor enthusiasts like Trout Unlimited, fiscal watchdog groups such as Common Cause, and individual landowners?needs this kind of data to effectively engage in the management of common resources.

"Increasingly, we propose to manage our ecosystems with sophisticated and complicated strategies," Bain says. "For example, we are attempting to manage agricultural runoff by changing how streams and floodplains are arranged. However, while designing these strategies, we tend to address the most recent impacts rather than the entire history of impacts. This can lead to wasted effort and misuse of relatively limited resources."

Legacy effects from human activities are all around us, says Bain, but few people ever give them a thought. For example, urban systems accumulate a lot of human-made materials, some of which have large ecological footprints and will ultimately leave a legacy. Bain cites the example of lead, which has been banned from gasoline and paint in the United States for several decades but can remain in soils for much longer periods of time. "We should be careful about growing food close to roads or near old houses," he cautions.

In agriculture, areas that were plowed hundreds of years ago react differently to contemporary acid deposition from air pollutants when compared with adjacent unplowed areas. Similarly, our extensive use of cement may add substantial amounts of calcium to urban soils, although the ecological impact of this practice is not yet fully understood, Bain adds.

Indeed, many landscapes that provide baseline ecological data for evaluating environmental change were structured in part by previous human interactions, such as settlements and agricultural practices. To make sense of the observed ecological patterns on such landscapes, Bain says, we must know something of the history of the processes acting to shape those patterns. A recent example of the need for historical data associated with the impact of humans is the debate over global warming and its associated climate change?the legacy of increased emissions of carbon dioxide and other greenhouse gases over millennia, but hugely accelerated since the industrial revolution and, especially, over the past several decades.

Bain points out that without a systematic collection of data recorded by the LTER Network, the broader geographical patterns of legacy effects would be much more difficult to detect. For example, scientists have discovered that recently glaciated areas have much less dirt accumulation than unglaciated areas. When Europeans first arrived in the eastern United States and dramatically changed local agricultural practices, eroded soil ultimately found its way into waterways. However, the glaciated areas produced less dirt, leaving less of an erosional signal in contrast to unglaciated areas, which lost more dirt and left such erosional legacies as buried valley bottoms and filled harbors. "In terms of policy, the management of glaciated and unglaciated areas requires different approaches," Bain says.

Nevertheless, Bain says, "although LTER sites have decades of data to draw from, we do not necessarily capture these changes, even with our best multidecade studies. It's hard to know what we might have been able to understand now had the LTER Network been established six or nine decades ago instead of three."

Another major benefit of the LTER approach, according to Bain, is the network of scientists that can jointly design a study, analyze the data, and produce such synthetic work efficiently. This type of historical analysis would take a small scientific team much longer to produce and perhaps be restricted to a smaller geographical and time scale than this regional synthesis of historical human legacies at long-term research sites in the eastern United States, Bain emphasizes.

Memory training unlikely to help in treating ADHD, boosting IQ

Thursday, May 31, 2012

Working memory training is unlikely to be an effective treatment for children suffering from disorders such as attention-deficit/hyperactivity or dyslexia, according to a research analysis published by the American Psychological Association. In addition, memory training tasks appear to have limited effect on healthy adults and children looking to do better in school or improve their cognitive skills.

"The success of working memory training programs is often based on the idea that you can train your brain to perform better, using repetitive memory trials, much like lifting weights builds muscle mass," said the study's lead author, Monica Melby-Lerv?g, PhD, of the University of Oslo. "However, this analysis shows that simply loading up the brain with training exercises will not lead to better performance outside of the tasks presented within these tests." The article was published online in Developmental Psychology.

Working memory enables people to complete tasks at hand by allowing the brain to retain pertinent information temporarily. Working memory enhancing tasks usually involve trying to get people to remember information presented to them while they are performing distracting activities. For example, participants may be presented with a series of numbers one at a time on a computer screen. The computer presents a new digit and then prompts participants to recall the number immediately preceding. More difficult versions might ask participants to recall what number appeared two, three or four digits ago.

In this meta-analysis, researchers from the University of Oslo and University College London examined 23 peer-reviewed studies with 30 different comparisons of groups that met their criteria. The studies were randomized controlled trials or experiments, had some sort of working memory treatment and a control group. The studies comprised a wide range of participants, including young children, children with cognitive impairments, such as ADHD, and healthy adults. Most of the studies had been published within the last 10 years.

Overall, working memory training improved performance on tasks related to the training itself but did not have an impact on more general cognitive performance such as verbal skills, attention, reading or arithmetic. "In other words, the training may help you improve your short-term memory when it's related to the task implemented in training but it won't improve reading difficulties or help you pay more attention in school," said Melby-Lerv?g.

In recent years, several commercial, computer-based working memory training programs have been developed and purport to benefit students suffering from ADHD, dyslexia, language disorders, poor academic performance or other issues. Some even claim to boost people's IQs. These programs are widely used around the world in schools and clinics, and most involve tasks in which participants are given many memory tests that are designed to be challenging, the study said.

"In the light of such evidence, it seems very difficult to justify the use of working memory training programs in relation to the treatment of reading and language disorders," said Melby-Lerv?g. "Our findings also cast strong doubt on claims that working memory training is effective in improving cognitive ability and scholastic attainment."
