Defaunation: 25% of the world’s birds disappeared in 30 years

Current extinction rates are estimated to be 100 to 1,000 times faster than during so-called “normal” geological periods. They have become so intense that a species can disappear in just a few decades. European birds have thus lost 25% of their population in only 30 years, which represents a loss of 500 million birds.

The scientists coaxing back nature with sound

When species disappear, so do their sounds. But scientists are exploring new techniques to use recordings of these very sounds to bring nature back.

Listening to Nature: The Emerging Field of Bioacoustics

Researchers are increasingly placing microphones in forests and other ecosystems to monitor birds, insects, frogs, and other animals. As the technology advances and becomes less costly, proponents argue, bioacoustics is poised to become an important remote-sensing tool for conservation.

The effects of defaunation on plants’ capacity to track climate change

Half of all plant species rely on animals to disperse their seeds. Seed dispersal interactions lost through defaunation and gained during novel community assembly influence whether plants can adapt to climate change through migration.

Archived soundscape recordings could be used for purposes we haven’t yet thought of. Watson agrees: “The beauty is [that] a kid who hasn’t been born yet will be writing algorithms that’ll be used to analyse historic data that we’re collecting and storing right now.”

Millions of people who once had to rely on their own eyes and ears to identify birds are now using Merlin to instantly tell them what they’re hearing. It can not only identify multiple birds at once, the app picks up the huge percentage of the species you can’t even see.

Tracking multiple species’ range expansions or contractions via a grid of listening stations could help scientists understand how environmental change disrupts the ecological connections among species and better plan nature preserves in a warmer future.

The Australian Acoustic Observatory (A2O) is a continental-scale acoustic sensor network, recording for a five-year period across multiple Australian ecosystems.

Australian researchers are installing 100 sets of recorders in different ecosystems across the country.

Acoustic enrichment can enhance fish community development on degraded coral reef habitat

Healthy coral reefs have an acoustic signature known to be attractive to coral and fish larvae during settlement. Here the authors use playback experiments in the field to show that healthy reef sounds can increase recruitment of juvenile fishes to degraded coral reef habitat, suggesting that acoustic playback could be used as a reef management strategy.

Beaked Whales Respond to Simulated and Actual Navy Sonar

These data are consistent with the conclusion that, similar to harbor porpoises [6], beaked whales are particularly sensitive in terms of behavioral responses to acoustic exposure.

In a 2020 paper, researchers described how they played recordings of rainfall to trigger breeding in frogs.

Biotic and abiotic sounds affect calling activity but not plasma testosterone levels in male frogs (Batrachyla taeniata) in the field and in captivity.
They measured the vocal activity and testosterone (T) of frogs after sound playbacks. In the laboratory, calling individuals had higher T levels than silent males.

Scientists are restoring oyster reefs off the coast of Australia using underwater speakers they made themselves to encourage wild oyster larvae back to the area to settle on the newly restored habitat.

Baby oysters follow the crackling sound of snapping shrimp

Though oysters may be brainless bivalves, they can “hear” and swim towards attractive sounds of the sea. This opens the possibility of playing marine sounds to attract oysters to reef restoration projects, accelerating their recovery.

So in 2020, armed with a pair of solar-powered loudspeakers and an MP3 player, Wegmann and his team set up a "seabird discotheque" to blast out bird calls 24/7 in an attempt to guide the eight missing seabird species home.

At the same time, a community science project run by the Natural History Museum is using people power to record roadside sounds all over the UK

to monitor biodiversity in these spaces.

Noisy neighbours: Listening in to nature in cities and towns

Researchers at the Museum are now working out how to use recordings from urban gardens, trees, soil and even ponds to monitor the biodiversity that lives in our towns and cities.

Can we fix our ocean noise problem?

Researchers are uncovering just how large the impact of man-made noise is on ocean life. But there are some surprisingly simple ways we could tackle this overlooked pollution problem.
https://www.bbc.com/future/article/20220712-how-to-fix-our-ocean-noise-pollution-problem

Hildebrand has called for a long-term, global ocean noise monitoring system that's accessible to anyone anywhere.

Not only would researchers be able to better track changes this way, activists or politicians looking to push for policy change could also easily refer to real-time problem areas.

More than 800 plants and bulbs have been planted in Bradford city centre to encourage insects to pollinate the area all year round.

Bradford's Darley Street Market garden bids to attract insects year-round.

Soundscape enrichment enhances recruitment and habitat building on new oyster reef restorations

Within just a few short years we've brought an extinct ecosystem back from the dead.
Enhancing marine soundscapes on newly constructed reefs using speaker technology may ensure sufficient recruitment to establish a trajectory of recovery for the desired habitat.

Bradford Live: Bat boxes added to city's new music venue

The animals with whom we share our cities

On the one hand, cities are heat islands where it can be difficult to survive. However, in a context of drought, they are also the only places where these animals will always find water. Paradoxically, cities could become a reservoir of biodiversity for these species.

Biodiversity Net Gain Bradford: Understanding BNG

Biodiversity net gain (BNG) is a planning system whereby developers consider the long-term impact a development project will have in terms of local biodiversity. It aims to ensure that biodiversity is left in a better state than before the development was completed for at least 30 years. This is done by avoiding loss of biodiversity, retaining natural habitats and ecological features.

Biodiversity Net Gain for local authorities

Biodiversity net gain (BNG) is an approach to development, and/or land management, that aims to leave the natural environment in a measurably better state than it was beforehand.
