A new study of European river restoration projects has indicated that their impact on the physical characteristics of rivers depends on the region, river type and restoration approach. However, regardless of the river, region or approach, impacts on the biodiversity of riverbed species is limited. Larger scale projects could be more effective.

The importance of predicting future threats to the areas connecting biodiversity hotspots when planning conversation projects is highlighted in a new study. Using Costa Rican forest as a case study, researchers compared forward-looking planning methods to those that focus exclusively on current threats and found the forward-looking approaches to be more effective and reliable.

Wealthier, more populated regions of Europe are more likely to have greater numbers of invasive alien species, according to researchers. A new study has indicated that human factors are more influential in encouraging alien invasions than the climate or whether the species are introduced to an island or a mainland region.

An analysis of conservation management strategies in the EU identifies a number of options for increasing the cost-effectiveness of conservation within the Natura 2000 network of protected areas. More time and money should be given to implementing conservation measures than planning them and governments should guarantee conservation funding over longer terms, say the researchers.

Grassland bird species of European conservation concern are potentially threatened by changes in land use in the Iberian cereal-steppes. However, a recent study suggests not all bird species respond in the same way to similar management guidelines and agri-environmental schemes need to be adjusted to local conditions.

The success of policy to maintain urban green areas depends on an adequate level of public participation, according to new research. The study compared two twinned European cities with different styles of green space management and found that public involvement may help maintain urban biodiversity.

A new European Environment Agency (EEA) report analyses approaches to estimating the value of ecosystem services on a large scale. The report provides suggestions for combining and scaling up data from individual, local studies to generate European or global valuations of ecosystems.

'Game theory' is a mathematical framework that aims to predict the performance of individuals or groups by considering the interaction between them. New research has applied game theory to three different cases of biodiversity conservation to predict conflict and offer broad suggestions for overcoming disagreements.

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.

A global team of marine biologists have recently completed a Census of Marine Life, which contributes to our basic understanding of marine ecosystems. Among its findings - marine biodiversity in the Baltic and Mediterranean are among the most threatened globally.

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.

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.

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.

Over one fifth of all the world's plants are at risk of dying out, according to a recent report. Loss of habitats through converting natural areas to agricultural use is the largest threat to plants, affecting 33 per cent of plants assessed by this study.

National lists of threatened species contribute to the monitoring of biodiversity, but new research has discovered a lack of these lists in certain countries, such as Pacific Island states, and for certain groups of wildlife, such as invertebrates. Targeted financial support, better knowledge sharing and standard systems of data collection could help bridge these gaps.

Human pressures on freshwater resources have seriously reduced the security of water for people and river biodiversity across the world, according to a recent study. Almost 80 per cent of the world's population is at high risk from threats to water security and 65 per cent of river habitats are under threat.

One-fifth of the world's mammals, birds, amphibians, reptiles and fish are threatened with extinction, according to a recent report. The study notes that there have been many conservation success stories, but far greater long-term resources are needed to improve the outlook for the world's threatened vertebrate species.

Restoring ecosystems in estuaries and along coasts is an important part of European environmental policy. A new analysis of degraded ecosystems has indicated that, although some restoration can take less than five years, when there has been a century of degradation, it can take a minimum of 15-25 years.

Social and economic aspects should be considered alongside environmental issues when valuing benefits provided by ecosystems and biodiversity. A recently published study outlines the use of multi-criteria assessment methods for valuation that simultaneously take into account a wide variety of economic, social and environmental decision criteria.

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.

New research from the Mediterranean suggests that marine ecosystems are disturbed by the organic food and faeces waste from fish farms, even when the pollutants themselves can no longer be detected. The study recommends calculating an individual pollution 'carrying capacity' for each type of marine habitat, and provides the first published estimate for a ma??rl habitat.

Tradable permits can be used to conserve biodiversity by allowing habitat destruction only when a permit has been acquired through the restoration of another habitat. New research has indicated that the costs of conservation, amount of habitat turnover and time lags in restoration all influence the efficiency of the permit market.

A recent analysis highlights the difference between the academic concept and the practical concept of ecosystem services. It suggests that academic science aims to discover and apply general and timeless concepts to measure ecosystem services, whereas in practice, stakeholders' valuations of ecosystem services vary with place and time.

Researchers have demonstrated how the ERICA Integrated Approach can be used to assess the effect of releasing radiation into the environment on local wildlife in a real-world situation. The study applied ERICA to a river in Norway and found that local wildlife was only exposed to low levels of radioactivity from the routine aquatic discharges of a nearby research reactor, although historical exposure was higher.

Conservation efforts should focus on species that have recently declined in number, are harmless or are perceived as high value, according to a European public survey. Participants also felt that disappearing habitats should be targeted for protection. The results suggest that, by choosing different criteria that more closely match the public's values and criteria, conservationists could improve public support for their work.

A new model, named OUTOPIE could help design more effective agri-environmental schemes. The model links the farm, field and landscape levels to allow a more accurate assessment of the costs of enrolling specific fields in conservation schemes. Using the model, the researchers were able to assess the cost-effectiveness of different policies for the conservation of the Little Bustard bird (Tetrax tetrax) in France.

Pollination of intensively farmed, flowering crops could affect the pollination of wild plants in neighbouring fields, according to a study by German researchers. In their one-year study, they found fewer bees visited wild plants that are close to oilseed rape fields, although the longer-term picture is less clear. The researchers warn that increasing cultivation of biofuel crops could possibly reduce wild flower populations.

Despite being high on the political agenda, biodiversity is still declining. A new analysis has focused on forest biodiversity in Finland, Russia and Peru and concluded that a global ecosystem approach can make a link between human and ecological systems but bottom-up initiatives are needed to effectively put the concept into action.

A tool to help conservation managers prioritise their actions to protect wildlife has been developed. The tool, based on a mathematical model, can provide guidance on conserving endangered species as well as dealing with pests and diseases. It may help conservation managers understand how best to use their limited resources.

Scientists have evaluated two decades of research into declining biodiversity and concluded unequivocally that loss of species richness leads to a reduction in how well ecosystems function. The researchers evaluated the evidence for key biodiversity theories and predicted that scientific progress in the next five to ten years will provide the information we need to efficiently conserve certain ecological processes.

Researchers have recommended new, improved ways of increasing the ecological value of European grasslands. Plant diversity ??? or species richness ??? can be increased by a factor of three through sowing grass and wildflower seed mixtures, together with a carefully controlled plan for animal grazing.

A proactive approach to biodiversity loss ??? where conservation of a species starts before it becomes endangered ??? could save millions of euros compared to the cost of recovering a population already in serious decline, according to new research.

Scientists have proposed new recommendations to increase the species diversity and sustainability of Mediterranean forests, since programmes to enhance reforestation by planting vast areas of pine trees have not been as successful as planned.

Over 160,000 seabirds are accidentally killed by global longline fisheries each year, according to a recent study. Better monitoring and standards are needed to reduce bycatch of seabirds in fisheries, including increased on-board monitoring of bycatches and mandatory best-practice measures, say the researchers.

There is a need for conservation strategies to consider the changing factors that threaten endangered species, such as climate change. Focusing on the European otter, new research has indicated that climate change will change this important freshwater species' distribution, which may mean that existing conservation areas no longer offer protection.

Setting aside agricultural land remains an important method of promoting biodiversity in Central Europe, according to new Hungarian research. Results have indicated that, compared to winter cereal fields, set-aside land has greater plant and insect diversity. This supports the continuing use of set-aside policy in Central and Eastern Europe.

Global food security under a changing climate is possible if the vital role of healthy ecosystems is recognised, according to a recent study. The researchers suggest that an ecosystem-based approach must be integrated with other measures to tackle food security under climate change, to protect ecosystems and supply the essential services on which humanity depends.

One strategy to halt the loss of biodiversity has been to create protected areas in the sea and on land. However, a new study suggests that unless additional measures are taken, particularly those that tackle human population growth and the increased use of natural resources, even the development of new protected areas will be unable to reverse the trend of global biodiversity loss.

Transport infrastructure and urban sprawl are increasingly dividing up landscapes in Europe, threatening wildlife. A new report has quantified landscape fragmentation across 28 European countries. To prevent further negative environmental impacts, it recommends protecting unfragmented areas, monitoring fragmentation and applying fragmentation analysis in planning.

New research has explored how well different governance systems can achieve desirable conservation outcomes. Results confirmed the importance of adaptive management, which relies on regular monitoring to enable 'learning through doing' to refine actions, and suggested that leadership using expert knowledge was also significant in successful governance.

Most species in an ecosystem could help supply essential ecosystem services, according to a recent study. The researchers found that 84% of species in the grassland ecosystems they studied contributed towards at least one ecosystem service. Losing any of these species would therefore degrade the ecosystem services such an environment could provide.

A new study has identified several differences between two major European databases on alien species, which could be communicating mixed messages for biodiversity policymakers. Researchers recommend creating a single pan-European database to address these differences.

Preserving species and the ecosystems in which they live is highly important to the progress of biomedical research. This is the conclusion made by researchers in an analysis of biodiversity's significance, which highlights the role of animals and microbes in improving our understanding of genetics, the regeneration of tissues and organs, and immunity.

Gardens are good for biodiversity, according to a study of intensively managed farmland in Sweden. The study has found that abundance and species richness of pollinating bees is higher near domestic gardens, with the pollination of a native plant also greater at these sites. Domestic gardens play a role in complementing 'natural' habitats for pollinators in impoverished environments.

While the ecological impact of shale gas exploration and extraction on groundwater has received considerable attention, the implications for surface water and terrestrial ecosystems is often overlooked, according to a new US study. Although more data are needed, preliminary results suggest that regulations based on proximity to surface water could be necessary to protect valuable ecosystems.

Hunting is not an effective tool for reducing damage caused by deer to managed forests in Europe, according to a recent assessment. Forests will be better protected through 'close-to-nature' management techniques, says the study, which evaluated the effects of different control mechanisms on deer populations and behaviour, including the influence of wild predators, such as wolves, and forest structures.

Plant biodiversity is crucial to the functioning of natural ecosystems in drylands across the world, according to recent research. Preserving plant diversity will be particularly important for maintaining the quantity and quality of services provided by ecosystems found in drylands that are vulnerable to the adverse effects of climate change and desertification.

High Nature Value (HNV) farmland is agricultural land that supports biodiversity and can be identified by its environmentally sound farming practices. New research on bird biodiversity on French HNV farmland has concluded that conservation of HNV farmland is important as well as conserving areas that were previously HNV and have undergone recent agricultural intensification.

Land-dwelling and charismatic animals, such as birds and mammals, receive greater attention in conservation research than other species. How does this bias affect those that are not so well known or loved? A new study suggests that African species in freshwater habitats may suffer as a result.
