A study published in Ecology reveals that elk bones can provide baseline ecological data on animal populations, complementing aerial counts and adding a historical component to live observation. The research found moderate shifts in elk habitat use despite recent changes at Yellowstone, including wildfires and wildlife reintroduction.
A Yale graduate student has developed a method for detecting an infectious pathogen driving amphibian extinctions worldwide. By analyzing preserved specimens, she found evidence of the pathogen in six older samples from Connecticut, revealing its early presence in the region.
Ecologists developed a series of new methods to monitor stag beetle numbers using ginger lures and tiny microphones detecting larvae sounds. These methods offer promise for conserving this rare species by providing an accurate picture of its abundance.
A new software package called CLASlite is revolutionizing forest monitoring by automatically identifying deforestation and forest degradation from satellite imagery. The technology has been adopted by 70 organizations in five countries and is being rapidly disseminated to support international policy discussions.
A new class of computational methods, called LoCoH (local convex hull) methods, has been developed to construct distributions of where monitored organisms are most likely to be found in space and time. These methods have proven especially useful in evaluating the spatial needs of threatened species and designing parks to conserve them.
Researchers at the University of New Hampshire are using satellite observations to track the ecology of avian influenza and develop early warning systems for potential outbreaks. By analyzing environmental data from satellites, they aim to understand how the virus spreads among poultry and wild birds in China.
Curtis Marean aims to reconstruct ancient ecological factors influencing human evolution and understand the future implications for modern humans. He believes a team-based approach will provide more fruitful research than traditional specialist work.
Researchers found that bottom gears like dredges and trawls inflict the most harm on habitats and marine vertebrates. The team suggests banning or limiting these gears in sensitive areas.
A new study by Imperial College scientists found that the power law used to determine the relationship between plant species and land area is not scale-invariant. Species richness accumulated rapidly at intermediate scales, rather than being constant as previously believed. This finding has significant implications for conservation stu...
Researchers at the Savannah River Ecology Laboratory have successfully developed a compound that aids in the extraction of certain underground contaminants, including lead. The new chemical compound targets specific reactive fractions of the soil and can be used in pump-and-treat extraction methods to enhance removal efficiency.
Ranchers are adapting to environmental changes by incorporating conservation techniques, such as managing grazing patterns and using native species. The symposium showcases successful examples of progressive management, including the use of beavers to restore woodlands and improve biodiversity.
The study found that aquaculture is contributing to the depletion of fish populations worldwide through inefficient practices and habitat destruction. The authors recommend promoting ecologically sound management and sustainable production methods to reduce the pressure on wild fisheries.
Researchers found that mountainous areas can receive dramatically different amounts of pollutants and excess nutrients, creating 'hotspots' with high ecological sensitivity. The study suggests that estimates of atmospheric deposition must take into account complex mountain landscapes, elevations, aspect, and vegetation type.
Research reveals that nectar robbing by bumble bees reduces pollen transfer and pollination success in the scarlet gilia plant. The study found that high robbing rates attract fewer pollinators, leading to decreased reproductive success.
The new edition explores the survival strategies of desert shrubs in resource islands, which support microclimate and soil health. Exotic plant species also invade areas of high native diversity, challenging traditional ecological theories.
A fishwheel harvesting method could benefit both fishermen's incomes and native salmon populations. The traditional method was banned in the 1920s due to large harvests and political conflicts, but is now being reconsidered as a potential solution to ecological and management problems.
Ecological researchers highlight gaps in evidence on biocontrol's safety record, citing potential ecological risks. The use of biological control methods in agriculture is being reevaluated due to concerns over environmental harm, but research suggests it can be an effective solution for certain pest problems.
Researchers find Candida wickerhamii yeast neutralizes pollutant in sauerkraut brine, producing Beta-glucosidase enzyme to extract natural flavors from fruit pomace. The technology can add value to foods and beverages by adding specific fruit flavors, such as natural grape flavoring.
