The Caucasus region, home to 51 globally threatened species, will receive a significant boost for conservation efforts thanks to $8.5 million in grants from the Critical Ecosystem Partnership Fund (CEPF). The funding will support conservation efforts across six countries, including Georgia, Armenia, Azerbaijan, Russia, Turkey, and Iran.
The reintroduction of wolves to Yellowstone National Park has led to a remarkable recovery of cottonwood and willow species, as well as improved stream health. Young trees are now growing taller in areas where wolves are present, suggesting that the fear of predation is preventing elk from overgrazing.
Researchers found that ozone reduces soil carbon formation, a key process for storing organic matter. The study suggests forests may be less effective at cleaning the air of excess carbon dioxide when ozone levels are high.
Researchers found that elevated ozone levels can reduce soil carbon formation, which is essential for forest health and climate regulation. The study's findings suggest that high ozone levels may hinder forests' ability to absorb excess carbon dioxide, threatening global efforts to mitigate greenhouse gas emissions.
Research reveals that the removal of great whales from the North Pacific Ocean led to a domino effect of ecosystem impacts. Killer whales preyed on other marine mammals, causing devastating effects on ecosystems.
The World Parks Congress has established a new reserve in Brazil that supports local communities and balances conservation with development. The Piagaçu-Purus Sustainable Development Reserve is part of six new reserves totaling 10.4 million acres, doubling the Amazonas State protected area system size.
The Brazilian state of Amazonas has announced the creation of six new protected areas, covering over 40% of its territory. These areas will help safeguard the region's rich biodiversity and support conservation initiatives.
Researchers found that catnip oil effectively deters termite tunneling, but its toxicity and cost limit its practical use. The study suggests a potential future for catnip oil as a natural termite control method.
The Northeastern States Research Cooperative has awarded nearly $1.8 million in research grants for studies of the Northern Forest and its communities. These grants will support projects such as measuring invasive species movement, tracking land use impacts on water quality, and evaluating forest ecosystem services.
A team of US researchers study Polish forest plots with 14 different temperate tree species to understand biodiversity and ecosystem structure. They investigate how tree species influence the environment, soil acidity, and decomposition.
Research by Michael Gundale found that non-native earthworms can endager rare plants like the goblin fern, which relies on fungi for energy. The study discovered a link between earthworm presence and thinner forest floors, threatening the long-term survival of these unique plant species.
A recent study published in Science suggests that conserving wild nature can generate significant economic benefits, with intact ecosystems providing up to 75% more value than converted ones. The research estimates a global network of nature reserves could provide $4.4 trillion in additional economic benefits annually.
Researchers found that whitebark pines, large ranges, and low human density are key factors in the survival of grizzly bears. The ESA has helped protect these areas, leading to increased bear populations in places like Yellowstone.
A new study by Scripps scientists reveals that intermediate-sized predators can have significant impacts on ecosystems, contrary to previous conclusions. The research highlights the importance of considering all species, not just larger ones, for maintaining ecosystem stability and biodiversity.
A study by McMillan and Larson found that rock climbing decreases vegetation diversity on cliffs, with only 4% as many vascular plant species on climbed faces. The researchers also discovered that climbing increases the proportion of non-native plants, which can outcompete native species for resources.
Gretchen Daily proposes assigning economic value to ecosystems and incorporating those values into public policy. She argues that making conservation profitable is crucial for saving the planet from natural resource depletion.
A NASA-funded study reveals that ancient South American forests hold the key to understanding US ecosystems before the industrial revolution. The study finds complex organic compounds as the main form of nitrogen in unpolluted ecosystems, contradicting previous beliefs about inorganic nitrogen.
A Princeton University study reveals that South American forests offer a glimpse into pre-industrial US ecosystems, showing complex organic compounds as the main form of nitrogen in unpolluted ecosystems. The findings suggest that high levels of inorganic nitrogen in the US are mainly due to acid rain and agricultural fertilizers.
Scientists have found that gradual changes in ecosystems can lead to catastrophic collapse, as even small disturbances can trigger irreversible shifts. This is evident in various ecosystems around the world, including coral reefs and forests.
Researchers are conducting field studies on three Hawaiian islands to examine the origins and evolution of plant life on Earth. The team is collecting plant samples in various ecosystems to identify invasive species and determine their impact on native biodiversity.
A new study reveals that North America does not absorb as much carbon dioxide as it emits, contradicting long-held assumptions. The research found that natural processes can only account for a small fraction of the released carbon dioxide, highlighting the complexity of climate change.
A study on Isle Royale National Park found that wolves' increased hunting efficiency in snowy winters led to a decline in moose populations, reducing browsing pressure on balsam fir saplings. This cascade of ecological responses highlights the potential impact of apex predators' behavioral adaptations to climate change.
