The current reserve system in the New World is inadequate, with only a tenth of protected areas reaching Disney World's size. Conservation investments may yield greatest impact in ten regions where biodiversity losses can be prevented.
A special section of BioScience provides in-depth analyses of assessment systems for protected area management effectiveness. Key findings include the need for more widespread use of assessments and monitoring, as well as the identification of critical management issues such as funding, staffing, and community relations.
A recent study assesses the jaguar's long-term survival prospects and identifies priority areas for conservation. The researchers found that the big cats are likely to survive in 70% of their current range, with the Amazon Basin being a key region for protection.
Prof Hugh Possingham, a renowned population ecologist, has been awarded the inaugural Fenner Medal for his groundbreaking work in applied and pure theoretical ecology. His research has significantly impacted environmental conservation efforts in Australia and globally.
A recent study by Janice Christian and Scott Wilson found that crested wheatgrass can precipitate a decline in soil quality and increase atmospheric carbon dioxide. The introduction of non-native species like crested wheatgrass may have far-reaching negative repercussions on ecosystems.
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.
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 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.
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.
