Several UN entities have issued a Blueprint for Ocean and Coastal Sustainability, which highlights the role of oceans in sustainable development and offers recommendations ahead of the UN Conference on Sustainable Development (UNCSD, or Rio+20).

This national action plan was developed through a series of multi-stakeholder consultative workshops with representations from national, regional and international biodiversity organizations.

Understanding the dimensions of pathways of introduction of alien plants is important for regulating species invasions, but how particular pathways differ in terms of post-invasion success of species they deliver has never been rigorously tested. We asked whether invasion status, distribution and habitat range of 1,007 alien plant species introduced after 1500 A.D. to the Czech Republic differ among four basic pathways of introduction recognized for plants.

Reliable estimates of the impacts and costs of biological invasions are critical to developing credible management, trade and regulatory policies. Worldwide, forests and urban trees provide important ecosystem services as well as economic and social benefits, but are threatened by non-native insects. More than 450 non-native forest insects are established in the United States but estimates of broad-scale economic impacts associated with these species are largely unavailable.

The establishment rate of invasive alien insect species has been increasing worldwide during the past century. This trend has been widely attributed to increased rates of international trade and associated species introductions, but rarely linked to environmental change. To better understand and manage the bioinvasion process, it is crucial to understand the relationship between global warming and establishment rate of invasive alien species, especially for poikilothermic invaders such as insects.

The Western Ghats is one of the world’s most heavily populated biodiversity hotspots providing for and supporting 400 million people. However, these diverse freshwater ecosystems face many threats because of untrammelled economic development.

Six Great Lakes states that unsuccessfully sought a court order to seal off the lakes from invading Asian carp on Wednesday asked other states to apply pressure on Congress to act.

Broad-scale studies of climate change effects on freshwater species have focused mainly on temperature, ignoring critical drivers such as flow regime and biotic interactions. We use downscaled outputs from general circulation models coupled with a hydrologic model to forecast the effects of altered flows and increased temperatures on four interacting species of trout across the interior western United States (1.01 million km2), based on empirical statistical models built from fish surveys at 9,890 sites.

Sri Lanka’s national flower (Nil Manel) is under threat of extinction due to hybridizing with a foreign species.

The high demand for frogs’ legs for consumption leads to the extinction of the species, says a report by international wildlife conservation groups. The report titled ‘Canapés to Extinction: The international trade in frogs’ legs and its ecological impact’ is the first ever rstudy on the frog leg market.
