Biodiversity benefits of organic farming could depend on context

Organic farming has often been found to have benefits for biodiversity, but the benefits can depend on the individual species and landscape in question. Research on vine farming in Italy suggests that the impact of organic methods on the number or diversity of pollinating insects may depend on local context. For example, the lack of connectivity between organic vine farms may limit benefits in some circumstances.

Moth and butterfly vulnerability to habitat fragmentation

The fragmentation of habitats is a growing concern for nature conservation. Butterflies and moths are particularly sensitive and new research has shed light on what makes some species more vulnerable than others. Those that are less mobile with more specialist diets and less reproductive potential appear to be more affected by habitat fragmentation.

Global biodiversity continues to decline

Indications suggest global biodiversity mostly continues to decline, confirming that the goal of halting the rate of loss of biodiversity by 2010 has not been met, according to a recent study. Pressures on biodiversity are increasing despite increasing policy and management responses. However, with greater resources and political will, the researchers argue that the loss of biodiversity could be halted or even reversed.

Conservation Systems improve resilience of biodiversity policy

Activists and policy makers are often considered to be separate influences on environmental issues. A new review suggests that the key to long-term conservation policy could lie in the creation of 'Conservation Systems'. These are a collective of activists, organisations and policy makers which could make biodiversity conservation efforts more resilient to major external changes, such as economic crises, change in government or conflict.

Reducing the potential 'ecological trap' of solar panels

Solar panels are attractive to aquatic insects because they reflect light in a similar way to water, indicates recent research. This has ecological implications, especially if insects lay eggs on the panels. However, if panels are surrounded by white borders and divided by white grids, they are considerably less attractive to the insects.

Current economic activity leaves an alien species 'invasion debt'

Past economic activity is more likely to explain the current pattern of biological invasions across Europe than recent human activities, according to a new study. It can take several decades before a newly introduced species becomes established and spreads, which may mean that recent invasions caused by current economic activities could create an 'invasion debt' for future generations.
