AGU journal highlights -- Aug. 31

Researchers investigate the cause of the Permian-Triassic extinction, finding that ocean acidification may have played a significant role. Additionally, studies suggest that reforestation on historically productive, snow-free land could contribute to climate change mitigation even in northern latitudes.

Poverty and national parks: Decade-long study finds surprising relationship

A decade-long study of people living near Kibale National Park in Uganda found that most households improved their prosperity, despite conventional wisdom suggesting parks contribute to poverty. The study suggests that parks provide a source of insurance for poor families, allowing them to hunt or sell park resources.

Warming climate likely to dramatically increase Yellowstone fires by mid-century

A new study projects that Yellowstone National Park will experience dramatic shifts in forest vegetation and fire patterns, with large fires occurring annually by 2050. The research suggests that a warming climate could lead to a fundamental change in the ecosystem, affecting wildlife, hydrology, carbon storage, and aesthetics.

Climate-change-induced wildfires may alter Yellowstone forests

A team of ecologists models climate change effects on fire occurrence and composition of Yellowstone forests, finding a tipping element that may alter the flora, fauna, and ecosystem quality. The researchers predict frequent fires will become the norm in parts of the landscape by 2050.

Study: Climate change to increase Yellowstone wildfires dramatically

A new study by UC Merced professor Anthony Westerling predicts a significant increase in large wildfires in Yellowstone by 2050, leading to changes in forest composition and wildlife habitats. The projected increase could result in fewer dense forests and more open vegetation, with some forests failing to regenerate after repeated fires.

Nanotechnology for water filter

Researchers at the University of Vienna have developed a method called "passive sampling" to measure the affinity of contaminants to carbon nanotubes. This method provides reliable results for realistic applications and can remove pollutants from contaminated water, making it a promising technology for water filtration.

Evolution of the evolutionarily minded

A new framework for the evolutionary analysis of the mind proposes that humans cannot be accurately portrayed as being adapted only to a Stone Age environment due to recent selection of genes. Experimental evidence suggests that humans utilize general learning rules rather than a modular account of cognition.

Northern Eurasian snowpack could be a predictor of winter weather in US, team from UGA reports

Researchers from UGA found a significant relationship between autumn snow extent in specific regions of Eurasia and temperatures across North America during the subsequent winter. Years with extensive autumn snow in northwest Eurasia were associated with winter temperatures seven degrees lower near the center of North America.

Lifelong gap in health between rich and poor set by age 20

A study by McGill University found that socio-economic status affects Canadians' health-related quality of life from a young age. The research analyzed data from 17,000 Canadians and found that poorer individuals start out less healthy than their wealthier counterparts and remain so over their lifetimes.

Coseasonality of influenza and invasive pneumococcal disease

A study found that infection with influenza likely increases the incidence of invasive pneumococcal disease (IPD). Influenza infection may increase the short-term risk of bacterial invasion in individuals already colonized with Streptococcus pneumoniae, which causes IPD. This suggests that some cases of IPD could be attributable to inf...

Mapping anemia risk in preschool-age children in West Africa

Researchers mapped anemia risk in preschool-age children in Burkina Faso, Ghana, and Mali using national cross-sectional surveys. The maps indicate the geographical risk profile of anemia, allowing for targeted control measures such as nutrient supplements and fortified foods.

Eye on the environment

Researchers are working closely with indigenous communities to develop interventions to address the health impacts of climate change. Pilot projects include medicinal herb gardens, online traditional health knowledge banks, and agricultural training programs.

Of moose and men

Researchers found that removing all road-side salt pools can reduce moose-vehicle collisions by as much as 79 percent. Moose are attracted to the high sodium concentration in salt pools, posing a significant risk to human and vehicle safety.

Striking ecological impact on Canada's Arctic coastline linked to global climate change

A recent study by Queen's University researchers reveals that the Arctic coastline is experiencing ecologically unprecedented impacts from global climate change. The team found that saltwater surges caused by rising sea levels have led to widespread die-off of coastal shrubs and dramatic changes in aquatic life.

Latitude and rain dictated where species lived

A team of scientists found that reptiles and mammals lived in separate areas due to differences in water availability, with reptiles thriving in drier temperate zones and mammals in water-rich tropical regions. This study helps predict the impact of climate change on mammal species distribution.
