CBER's contribution to WWF’s conservation technology

CBER’s Rory Gibb and Ella Browning (under Kate Jones’ guidance) wrote and provided guidelines for the World Wildlife Fund on best practice on using the audio and camera trap data. This information is crucial for new researchers or external companies who are investing in such technology or using it to make informed decisions with nature at the forefront. Please visit WWF's website for further information.
WWF is the world’s leading independent conservation organisation.

Biases of acoustic indices measuring biodiversity in urban areas

Ecoacoustic monitoring uses the sounds emitted by wildlife as a proxy measure for biodiversity. Massive volumes of ecoacoustic data can now be generated using passive acoustic recorders, but extracting useful information about the biodiversity sounds recorded in this data is unfeasible without automated methods. Acoustic indices (AIs) are algorithms which generate community-level measures of biodiversity, such as activity, diversity and disturbance, from audio data. However, the suitability of ecoacoustics for monitoring urban biodiversity, and the performance of AIs on the noisy audio data typically generated in cities, is unknown.

Hot topic: The conservation value of secondary savannas in the Brazilian Cerrado

Text and photos by Guilherme B. Ferreira
As an ecologist I’m familiar with the term ‘secondary forest’, but ‘secondary savanna’ is a much more obscure concept. So, how should we name an area of Cerrado – the Brazilian savanna – that has regenerated after clearcut?  And more importantly, what’s the biodiversity relevance of these areas of regenerated Cerrado?
The answer to the first question, according to a recent review, is that the secondary concept (as well as the old growth one) should be equally applied to forests, savannas and grasslands. Answering the second question is much trickier, though. The regeneration and succession in Cerrado vegetation has been studied at some locations; in general it follows a path from open to dense vegetation, with an increase in tree and shrub density and a decrease in the herbaceous cover. However, while we have an idea of the differences in vegetation composition and structure between old growth and secondary savanna vegetation in the Cerrado, there is virtually no study comparing the fauna that lives in these two different environments.
To start filling this gap in knowledge we conducted a camera trap survey in a Cerrado protected area harbouring large areas of secondary as well as old growth savanna. Our study area is a perfect site to investigate the effects of secondary savanna on biodiversity because more than 1/3 of its 310 km2 have naturally regenerated after clearcut, while large portions of the state park have been kept in its natural state with little human interference.

Smart detectors to monitor urban bat life

The activity of urban bats in Queen Elizabeth Olympic Park in London is being monitored in real-time using new, automated smart detectors that have been developed and installed by UCL and Intel scientists in collaboration with Arup, the Bat Conservation Trust and the London Wildlife Trust.
