The greater sage-grouse and Gunnison sage-grouse are affected by changes in their ecosystems, including the suppression of fire and invasive species. Livestock grazing also impacts these birds, while oil and gas development threatens the sagebrush biome. Researchers discuss restoration options to mitigate these effects.
A new paradigm for fishery management prioritizes ecosystem health over individual species, considering predator-prey relationships and habitat quality. The approach aims to reduce destructive single-species management, instead focusing on the entire food web.
A recent study reveals a drastic decline in species diversity and productivity of an ecosystem, with significant consequences for the environment. The research highlights the need for conservation efforts to mitigate these effects and preserve biodiversity.
The US Commission on Ocean Policy released a preliminary report outlining bold and broad-reaching recommendations to reform the nation's ocean policy. The report emphasizes ecosystem-based management, strengthening science and education to inform decision-making, and enhancing regional goals and priorities.
Salvage harvesting operations after natural disturbances can threaten some organisms when large quantities of biological legacies are removed. Researchers argue that exempting large areas from these practices is crucial for ecosystem recovery and sustainability.
The US government is expected to issue a draft report with recommendations for ocean policy, addressing issues like resource stewardship and pollution prevention. The commission's report emphasizes the need for ecosystem-based management to sustain long-term exploitation.
National Ocean Commissioners and scientists propose a holistic ecosystem-based approach to manage the oceans, shifting from single-species management to integrated governance. This approach aims to restore ocean health by considering the interconnectedness of species and ecosystems.
A team of researchers at Michigan State University has uncovered cliques in the food web, a complex network of interconnecting food chains. This breakthrough provides a new way to understand and manage ecosystems for sustainability.
The Bechtel Foundation has donated $300,000 to support the development of an atomic testing museum at the Desert Research Institute's Frank H. Rogers Building. The museum will feature exhibits on the Cold War role of the Nevada Test Site and traveling exhibits from the Smithsonian Institution.
Researchers from PISCO integrate genetics, microchemistry, and computer mapping to understand coastal ecosystems. They discover coastal hotspots with abundant food and faster growth rates, and track larvae movements using mini-flight recorder technology.
Researchers are using innovative new tools to study coastal ecosystems, including genetic mapping of marine populations and remote ocean sensing. These tools are helping scientists understand the dynamics of ocean environments and track the movement of marine species.
A study found that California's marine reserves cannot protect the state's low red abalone population from being overhunted by sea otters. The researchers suggest that single-use reserves focus on either ecosystem restoration or fishery development instead.
A URI biologist will monitor salt marshes in national parks for long-term ecosystem changes, enabling resource managers to anticipate detrimental changes and design management strategies. The study sites were selected based on aerial photography, field visits, and interviews with park staff.
The Ecological Society of America advocates for a broader view of freshwater resources, prioritizing ecological needs alongside societal requirements. Healthy freshwater systems provide essential goods and services like food supply, flood control, and habitat, which are costly to replace with technology.
USGS scientists Jon Keeley and C.J. Fotheringham argue that natural fire regimes in chaparral ecosystems are not characterized by frequent small fires, but rather by landscape-scale crown fires. They suggest that limited, strategically placed burns are more cost-effective than large-scale prescription burning.
The Wildlife Conservation Society will use the grant to manage and protect key areas with intact ecosystems, such as the Ndoki-Likouala rain forest in the Republic of Congo and the Greater Yellowstone Ecosystem. WCS's Living Landscapes approach aims to balance human needs with wildlife conservation.
Recent research reveals a mix of natural and human-induced changes in Florida Bay, with a significant increase in the mussel species Brachidontes exustus and a decline in molluscan diversity. Understanding natural variability is crucial to restore ecosystems to their natural state.
Historical records show that humans exploited coastal resources thousands of years ago, leading to the decline of top predators and smaller species. Wise management strategies, such as restoring native oysters and promoting aquaculture, can help conserve water quality and create habitats for fish and shellfish.
A two-year study of human impacts on oceans over time reveals that overfishing was the primary driver of ecosystem collapse in each case examined. Historical overkill of marine life triggered changes in ecosystem structure and function, leading to toxic algal blooms, dead zones, and outbreaks of diseases.
The 9th International Coral Reef Symposium in Bali, Indonesia brings together experts to discuss the state of global coral reefs and potential solutions to address mass coral bleaching and die-offs. The conference highlights new insights into mystery diseases killing coral reefs and breakthroughs in Marine Protected Areas.
The symposium explores the ecological implications of these stressors on Western mountain ecosystems. Research has helped quantify stress effects at regional scales, challenging land managers and policymakers.
The Fish and Wildlife Service is pioneering the ecosystem approach by dividing the country into 53 management units based on watersheds. Conservation biologists are urged to help implement this approach by working with land managers on Habitat Conservation Plans, identifying areas for flexibility and adjustments.
New studies suggest ecosystems can be disrupted by small environmental changes or loss of minor species, challenging conventional wisdom on ecological protection. Research finds importance of both keystone and lesser species in ecosystem function.
Researchers study old-growth forests' carbon, water, and energy exchange to understand their role in global climate change. The project aims to provide baseline information on managed ecosystems' impact on global carbon budgets.
