Somewhere in the ocean off Southern California, there's an effort underway to help the endangered white abalone make a comeback.

Their numbers have been decimated by decades of overfishing and disease - but a project to revive the species recently hit a critical milestone.

In a secret spot off the greater Los Angeles coast, thousands of the shellfish that were born and painstakingly raised in tanks are now getting their first taste of freedom.

There is a common assumption that plant species are more inclined to thrive in a non-native community than a native one, sometimes becoming 'invasive'. However, this behaviour is likely to be quite unusual and invasive alien plants are actually an important exception, according to a new study. Much can be learned from the population of a species 'at home' and should be included in official assessment criteria.

A new study reports that fishing depths in the EU have increased, with more deep-sea fish species being harvested. Deep-sea fish populations are often more vulnerable to effects of fishing, and the ecological impact of overfishing may therefore be greater than for shallow-water species.

Assessing the potential of new environmental management tools often brings an ???innovation dilemma???: is it better to stick with what is known to work, or to implement new measures that are potentially more effective, but also more uncertain? Researchers have proposed an approach to deal with these dilemmas, and applied it to the case study of an invasive species programme in the US.

Neither the public nor conservation managers are fully aware of the different risks posed by invasive alien species (IAS), new research suggests. A study examining perceptions of five invasive species in the UK shows that both conservation managers and the public regard some highly damaging species as ???low risk???, and that their awareness does not increase with the amount of scientific research on the topic.

Invasions of alien species are rising at an alarming rate, largely due to growing global trade and transport routes. Preventing the successful establishment of alien species by better understanding the factors determining success is a step toward limiting the threat of future biological invasions. Statistical modelling using observed bird invasion data — including location, event and species-level factors showed which factors were key to successful establishment by the alien species.

A survey of over 600 private boats docked in marinas throughout the Mediterranean showed that 71% are carrying non-indigenous species. In certain cases, non-indigenous species can become ‘invasive’ and have enormous and long-lasting impacts on ecosystems. The findings suggest that a common monitoring strategy may be necessary to prevent further disruptions to natural ecosystems.

The public can help assess the human impact on wild birds through amateur ‘citizen science’ networks, according to new research. Scientists evaluated the suitability of data collected by amateur bird-watchers for long-term monitoring of European bird populations. Their findings suggest that citizen data may significantly improve the accuracy of existing official survey methods, as well as help increase public awareness of wild bird conservation.

A new framework to help decide whether to translocate species that are threatened by climate change has been developed. The framework provides a simple method of assessing different strategies and ensuring that limited budgets are used effectively.

An early warning system to predict the overfishing of individual species, far in advance of severe population decline, has been developed by researchers. The ‘eventual threat index’ was applied by the researchers to historical data on tuna and billfish populations, and accurately predicted their current declines as early as the 1950s.

A new tool to help environmental managers make faster, more evidence-based decisions on how to eradicate alien aquatic species has been developed. The tool is a statistical model based on over 140 management case studies in the scientific literature. Packaged as a user-friendly computer program, it allows different management options to be easily compared.

Scientists today announced the discovery of a new species of pterosaur from the Patagonia region of South America. The cranial remains were in an excellent state of preservation and belonged to a new species of pterosaur from the Early Jurassic. The researchers have named this new species 'Allkauren koi' from the native Tehuelche word 'all' for 'brain', and 'karuen' for 'ancient'.

A recent study has revealed that grassland plots planted with a mixture of several agricultural plant species produced a greater yield than plots planted with a single species. The findings provide valuable evidence for scientists, farmers and policymakers who strive to increase the productivity of grassland, while reducing input of nitrogen fertilisers.

Species will have to shift their range much faster in some areas of the world than others to keep pace with climate change, according to new research. Those that live in certain areas, such as mangroves, tropical basins and deserts, may not be able to move fast enough over the next 100 years to survive.

How does climate change cause extinction? An extensive analysis of the available evidence has explored this question and concluded that climate change’s effects on the interactions between species is likely to be the main reason for local extinctions. For example, climate change may lead to the loss of prey for predators.

Shifts in species’ ranges are expected under climate change, as organisms move to find suitable conditions. New research in the Mediterranean Sea has found that the way species interact could also have a significant effect on their resilience in a changing climate.

Mussels exposed to high levels of microplastic pollution display signs of stress, new research has shown. However, levels of exposure were higher than found in the wild and no effect on the energy reserves of either mussels or lugworms was observed in the lab. tests. The researchers caution that longer experiments may be needed to reveal microplastics' full effects.

Researchers have proposed an approach to deal with these dilemmas, and applied it to the case study of an invasive species programme in the US.

The joint threat posed by climate change and invasive alien species can have different effects on endangered native species, new research suggests. This European study predicts that the invasive zebra mussel may benefit from climate change, negatively affecting native mussel populations; but both invasive and native crayfish could suffer declines.

Wetland biodiversity may fall under climate change, a new study suggests. The researchers' experiments indicated that, overall, plant growth in wetlands will be boosted, but a small number of plant species well suited to the warmer conditions will out compete other species. However, climate change's effects on biodiversity may be less severe if plants are able to move to cooler locations, towards the poles.

Areas of mariculture — where marine organisms are cultivated for food — have been identified as important source areas for the dispersal of invasive alien species (IAS) via artificial floating litter. In order to identify IAS at high risk of dispersal via this method, researchers have analysed fouled anthropogenic litter sampled on beaches in two important European mariculture areas. Overall, the team detected eight aquaculture-related IAS attached to anthropogenic litter. All of these species are well adapted to rafting on artificial surfaces and have high potential to disperse in this way, suggesting that they are suitable candidates for closer monitoring and policy action in the future.
