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.
A study found that pine cones' spines hinder finches' ability to access seeds, encouraging seed dispersal. Researchers discovered a link between spine growth and the length of time seeds remain on pine cones.
Two studies published in Ecological Applications found that wildlife corridors increase the movement and population density of butterflies and other habitat-restricted species. The most effective corridors were those that connected isolated patches of open space with existing forest, allowing for improved plant diversity and food sources.
A long-term study of a kelp forest community found that large-scale, low-frequency events like El Nino and La Nina drive changes in the community. The study also highlighted the importance of understanding how different species adapt to changing environmental conditions.
The latest Ecology journal edition examines the survival of Yellowstone grizzly bears, which remain threatened despite intensive management. Ferns also play a crucial role in determining forest composition by filtering tree growth rates. Earthworms shed light on plant responses to climate change through their nutrient-rich castings.
Researchers study hybrid species' genetic makeup and impact on ecosystems, challenging existing paradigms. Some studies find hybrids to be more fit than their parents in certain environments, while others reveal increased susceptibility to parasites.
The US National Park Service faces challenges in managing wildlife populations due to conflicting goals and limited information. Adaptive management is proposed as a solution to resolve these issues. The study of ecological systems reveals new insights into what may be ecologically appropriate decisions regarding park management.
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.
The Ecological Society of America will host three symposia on topics such as the impact of urbanization on water quality and animal life, the effects of non-native species invasions, and research into sustainable land-use practices. The symposia aim to explore options for managing invasive species and promoting sustainable urban systems.
A new study reveals Argentine ants' success mechanisms, including numerical advantage and lack of natural enemies. The ants' unique colony structure and ability to form large supercolonies enable them to dominate native ant populations.
A new study found that cannibalism among flour beetles regulates population growth and stabilization. By manipulating life stages, researchers demonstrated a link between cannibalism and stable populations.
Researchers found that invasive non-native plants compete with native species for regeneration opportunities, inhibiting native tree seedlings and juveniles. Invasive species exhibit similar ecological roles as natives, posing a threat to conservation efforts.
Researchers found that smoke directly penetrates seeds, triggering germination, and that various factors influence the process, including charred wood, Nitrogen dioxide, and soil moisture levels. The study suggests fire behavior has a significant impact on post-fire ecosystems.
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 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.
Ecological economists suggest that economic growth is unsustainable and must be rethought to prioritize sustainability. The field of ecological economics aims to minimize growth while improving quality of life by exploring new strategies to reach sustainable social and economic systems.
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.
