Intensive agriculture is changing migratory route for birds

New research suggests that many Ruffs are changing their migratory route when flying north to their breeding grounds in northern Europe and to Asia from Africa. This is because their food supply has been reduced by the effects of intensive agriculture in the Netherlands, where they commonly stop off, causing them to shift eastwards to stopping-off points in Eastern Europe instead.

Future warming could cause trees to dominate peat bogs

Research suggests that climate change could alter the structure and function of temperate peat bogs and that these changes are primarily driven by rising temperatures, rather than periods of temporary drought. An average temperature rise above 1??C could permanently shift moss-covered peat bogs into bogs predominately covered with trees, affecting their ability to store carbon and the existing carbon stocks in them.

Translocation for conservation: helping or harming wild populations?

The value of moving animals or plants from a stable population into one that is endangered or even extinct has been questioned, with some suggesting that it will mean that the new population is not well adapted to its environment. However, research on an endangered toad has shown that even when individuals were translocated from great distances, the population was able to genetically adapt to local conditions within a few generations.

Device that emits natural warning calls reduces train-animal collisions

Animal-train collisions are an important cause of animal mortality. This study tested the ability of a device that emits natural warning calls to reduce risk of animals being hit by trains in central Poland. Animals, including roe deer (Capreolus capreolus), red fox (Vulpes vulpes) and brown hare (Lepus europaeus) escaped in most cases. The authors say the device is an effective means of risk reduction as it allows animals to escape train tracks earlier and more often.

Presence of invasive American mink shifts the sex-ratio of the European polecat across Europe

The invasion of the American mink (Neovison vison) is linked to a shift in the adult sex ratio of the native European polecat (Mustela putorius) across its entire range, a new study has discovered. Through aggressive competition, the American mink has decreased the number of reproductive female European polecats. This is the first study to identify such an effect upon a native species across its entire range in Europe.

Ecological intensification farming benefits wildlife and increases yield

Ecological intensification, using land and resources in ways that minimises negative ecosystem impacts while maintaining agricultural productivity, has been proposed as a way to sustainably increase crop yields, but remains under debate due to a lack of evidence. This six-year study of a large commercial farm assessed how using land for wildlife habitat affected food crops. The study shows that it is possible to remove up to 8% of land from production and maintain (and in some cases increase) yield.

Top predators maintain regulating role in human- dominated landscapes – but human activity is greatest limiting factor on other species

Large carnivores play important roles in ecosystems by regulating populations of herbivores and other species. Understanding how human activities affect the role of predators, particularly within human-modified systems such as agricultural landscapes, is therefore important. This study investigated how predator and prey populations were distributed in Transylvania, Romania, and assessed them in relation to human activities. The research highlights how relationships between large carnivores and people need to be considered as part of biodiversity conservation efforts, especially considering the successful recovery of several large carnivore populations within the EU.

Agri-environment schemes should be diversified and customised to meet habitat preferences of different species

The Natura 2000 network is the backbone of nature conservation in the EU, and agri-environment schemes (AES) are an important tool to protect biodiversity on European farmland. A recent study, which investigated the effectiveness of AES in relation to grassland birds in Poland, found that AES were not associated with species richness of target species, and proposed a number of reasons for this. The researchers recommend that AES management regimes should be diversified and customised to provide optimal habitat for a wider range of bird species.

Organic farming enhances pollination but may reduce yield compared to agri-environment schemes

There are several types of wildlife-friendly farming scheme, some of which are more prescriptive than others. A recent study compared the effects of different wildlife-friendly farming approaches, including organic farming, on pollination. The findings suggest that organic farming practices enhance pollination services but may compromise crop yield. ‘Conservation Grade’ farming schemes — biodiversity-focused practices funded by sales of labelled food products — can support both pollination and yield.

Warming in the Channel leads to a decline in cold-water fish

Results from a long-term study of fish communities in the Bay of Somme in the English Channel show that numbers of cold-water fish, such as dab and plaice, have been dropping since 1998, as sea temperatures have risen. The researchers say this is evidence of ‘tropicalisation’ in an English-Channel ecosystem. The findings may have implications for conservation policies in the Bay, which is a Marine Protected Area1 designated under the Natura 2000 programme, as well as other marine sites affected by warming.

Mussel study determines risk posed by rare earth metals to marine environments

Rare earth elements (REEs) are used increasingly often in innovative technologies, causing these elements to enter the natural environment. They can be sourced via deep-sea mining, raising concerns about marine exposure to mining processes and waste products. This study examined how two REEs, lanthanum and yttrium, affected and stressed marine ecosystems, using young marine mussels (Mytilus galloprovincialis) as indicators of water quality. The researchers determine a parameter known as the ‘predicted no effect concentration’ (PNEC) for La and Y — the maximum environmental level of each of the two elements at which no effect is seen on the most sensitive organisms and which is, therefore, deemed safe for the environment.
