Bioshields - coastal protection or harmful alien species?

Planting vegetation to protect coasts from natural disasters, such as tsunamis and cyclones, may damage native ecosystems, according to a new study. As there is also questionable evidence on the effectiveness of these 'bioshields', the study suggested a re-think on coastal vegetation policy and research.

Wealthier European regions have more alien species

Wealthier, more populated regions of Europe are more likely to have greater numbers of invasive alien species, according to researchers.

Implementing Natura 2000: Dutch and Italian experiences

A study of how the Natura 2000 network was implemented in the Netherlands and in Italy has been conducted. From this analysis, recommendations have been made to help other EU Member States implement and manage the network, which include providing local authorities with better information on and understanding of Natura 2000 and how to balance ecological, social and economic needs.

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.

Habitat quality is better than quantity for species survival

A new study suggests that improving the quality of existing wildlife habitat is more important than creating new habitat, when attempting to counteract the negative effects of climate change on species survival. This suggests that resources would be better directed towards habitat rehabilitation and reforestation than building new habitat features.

Driven by trade, the spread of alien species is increasing worldwide. This study combined 60 years of trade data with that on biodiversity and climate to model the spread of plant species across 147 countries.

Quality of urban waterways found to affect bat populations and biodiversity

Urban waterways can provide foraging opportunities for a range of bat species.

Golden jackal should not be treated as an alien species in Europe

Expansion of the golden jackal (Canis aureus) across Europe has led to its designation as an alien species in some Member States. In the first continent-wide study of the species, researchers characterise the genetic structure of the European population and attempt to identify its origin. The results suggest the golden jackal was not introduced to European countries by humans and therefore should not be treated as alien.

Localised adaptation makes some oysters more resilient to climate change than others

Olympia oysters (Ostrea lurida) have been shown to adapt to local environments that are as little as 20 km apart, and these adaptations can be passed on to offspring. In this study, oysters that originated from less saline areas tended to be more resilient to extremely low saline conditions than oysters from more saline areas. Since episodes of reduced salinity are a predicted effect of climate change in the San Francisco Bay area under study, the authors say their findings could be useful for future conservation and restoration efforts.

How big a threat do invasive alien species pose to European biodiversity? A ranking of species for urgent risk assessment

Invasive alien species (IAS) pose a threat to native European biodiversity and cost the EU annual damages worth EUR 12 billion as a result of IAS effects on human health, damaged infrastructure, and agricultural losses. IAS are the focus of Target 9 of the Convention of Biological Diversity (CBD) and Target 5 of the EU Biodiversity Strategy: ‘By 2020, IAS and their pathways are identified and prioritised… pathways are managed to prevent the introduction and establishment of new IAS.’ The EU framework for action against IAS is set out in a Regulation adopted in 2014. This provides for the adoption of a list of IAS of Union concern that will be subject to restrictions across the EU. The first step in order to consider a species for listing is to undertake a risk assessment.

Soil quality to decline as climate change hinders litter decomposition by soil fauna

Identifying valid surrogates for amphibians and reptiles in pesticide toxicity assessment

Environmental pollution is putting amphibians and reptiles at risk, yet these animals are not included in regulations regarding the environmental risk assessment (ERA) of pesticides. The extent to which other species already used in pesticide toxicity assessment (including fish, birds and mammals) can serve as effective surrogates is currently under debate. This study conducts a systematic review of the available literature. The results reveal a positive correlation between toxicity recorded on fish and aquatic amphibians, but indicate that birds and mammals are generally not good surrogates for reptiles and terrestrial amphibians. Moreover, some chemical-dependent trends were detected, with a number of insecticides found to be more toxic to amphibians or reptiles than to potential surrogates. These findings highlight an urgent need for further research to reduce uncertainties and contribute to future policymaking regarding the protection of amphibians and reptiles from potentially harmful pesticides.

Salicylic acid poses no current threat to marine ragworms, finds acute Portuguese study

Contamination of the aquatic environment by pharmaceutical drugs used in human and veterinary medicine is an emerging issue, as it can cause toxic effects in biological systems. This study explored how the marine organism Hediste diversicolor, a polychaete worm, responded to exposure to salicylic acid, a key component of aspirin. They found the species to adapt and respond in a way that minimised the effects of metabolising the contaminating compound, suggesting that the acid does not currently pose a threat to marine polychaetes.

Earthworms are essential for soil quality, reducing crop pathogens and ensuring yield

Soil biodiversity, soil quality, and soil health are integral to protecting the natural environment. Soils are crucial to food production and human well-being, as highlighted by the UN Sustainable Development Goals (SDGs).
