A new study evaluates the efficacy of using shade-grown coffee as a bird conservation measure. Researchers found that while shade coffee habitats support many birds, some sensitive forest species still need forests to survive. Protecting canopy shade trees in these plantations is crucial for conservation.
The University of Iowa's contribution to the Cluster 2 space mission will analyze plasma waves in Earth's magnetosphere, predicting space weather events. The US experiment will also enable a unique telescope-like system for studying low-frequency radio emissions.
Dr. David Suzuki will speak at the Ecological Society of America's annual meeting, discussing his efforts to prevent ecological crises and find ways for humans to live in balance with nature. He focuses on Climate Change and Pacific Salmon Forests, aiming to educate the public about urgent strategies for reducing global warming.
Researchers have found that most of the interstellar dust particles consist of 3-dimensionally cross-linked organic macro-molecules, called polymeric-heterocyclic-aromates. These molecules have been detected in five impact mass spectrometer samples from NASA's STARDUST spacecraft.
The Ecological Society of America has released three new publications on biodiversity, biotic invasions, and forest management. The reports provide insights into how changes in ecosystems affect productivity, stability, and environmental damage. The ESA also offers expert advice for managing U.S. National Forests sustainably.
The XMM-Newton satellite is now operational, sending home images of celestial objects and observing bright binary stars, pulsars, and cataclysmic variables. It will study massive black holes and exotic stars, mapping the cosmos to greater distances.
A team of scientists from NASA and Max Planck Institute observed the deflection of galactic dust grains by solar radiation, finding that radiation pressure is stronger than solar gravity for certain mass ranges. This phenomenon affects the trajectory of dust particles near the Sun, causing them to move slower and be deflected.
The University of Iowa team will use a low-frequency radar to probe beneath the Martian surface and study the planet's ionosphere. The goal is to detect signs of liquid water, which may be responsible for carving the planet's canyons.
A symposium by the Ecological Society of America explores the delicate balance between the benefits and risks of genetically engineered organisms. The discussion will cover case studies on engineered plants, arthropods as tools in disease control, and risk assessment in ecosystems.
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.
An international team of scientists identified regions on the Sun where the high speed solar wind originates using the Solar Ultraviolet Measurements of Emitted Radiation spectrometer on SOHO. The research will lead to a better understanding of the solar wind's effect on Earth's space environment.
An international team of scientists analyzed satellite radar measurements, finding no significant melting or instability in the West Antarctic ice sheet's middle section. The study suggests the answer to whether global warming affects its stability is no, at least for now.
Precious Woods Ltd, a forestry company in Brazil, has been awarded the ESA Corporate Award for its innovative approach to sustainable forest management. The company's use of advanced planning and ecological principles has resulted in the conservation of 97% of primary forest in the State of Amazonas.
The Duke scientists analyzed past climate changes and found that the region rapidly changed with even short-term climate fluctuations, making it susceptible to drastic ecological changes. The researchers expect that global warming will significantly increase temperatures worldwide over the next century, leading to shifts in air masses ...
The USGS presents various studies on invasive species, including a workshop on non-native plant invasions and their impact on native ecosystems. Additionally, researchers discuss the effects of grazing on plant species diversity and find that habitat conditions play a significant role in shaping species variation.
The report highlights the problems caused by nonpoint source pollution, including eutrophication, which can lead to fish kills, coral reef destruction, and shellfish poisoning. The report provides solutions, such as reducing fertilizer applications, improving sewer systems, and restoring wetlands.
Researchers are exploring ways to control the rush of nitrogen and other chemicals into the Mississippi River watershed. Ecotechnology may hold the answer by restoring or building wetlands and riparian buffer zones along waterways.
Researchers found that urbanization reduces stream diversity, but tolerates insects like midges, which are pollution-tolerant. Stream quality is affected by factors like road runoff, pavement pollution, and sediment, highlighting the need for sustainable land use practices to preserve aquatic ecosystems.
The MAX-Planck-Gesellschaft launched the EQUATOR-S satellite in 1997, after years of development. The spacecraft aims to explore the Earth's magnetosphere and study the aurora borealis, providing valuable insights for the Inter-Agency Solar-Terrestrial Physics Program.
Researchers found that Rhododendron maximum restricts the formation of mycorrhizal fungi associations with certain tree species, particularly hemlocks. This limitation combined with resource scarcity hinders young oak seedlings' ability to absorb nutrients, giving Rhododendron an advantage in nutrient competition.
The Endangered Species Act's economic impacts are unclear due to inadequate data, according to a University of Wyoming economist. The lack of scientifically-based national estimates of the economic benefits of most listed species limits decision-making.
A genetic analysis by University of Illinois researchers reveals that Illinois Prairie Chickens have lost significant genetic diversity due to population decline, affecting their fitness. The study suggests introducing birds from neighboring states may help restore the species' numbers and health.
The SOHO mission has provided stunning images of the Sun's south polar region, revealing that even in quiet areas, there is tremendous activity. The observations suggest that solar plumes are associated with small regions of high magnetic activity and are more dynamic than previously thought.
