Classification of animals observed or collected for biological inventories predominantly relies on visual attributes. However, many animals generate acoustic signals for communication and orientation, which are predestined for eavesdropping on their presence and behaviour. Acoustic signals can be registered over varying distances, allowing for unobtrusive detection and observation of their producers. Acoustic observations are well established for e.g. birds, insects, anurans, bats or whales. Depending on type of signals and taxonomic group, species identification, abundance estimation or behavioural assessment is possible. But physical properties of sound require certain precautions during recording, analysis as well as interpretation. We outline these prerequisites, describe types of bioacoustical signals for major taxonomic groups, and present a short review on state-of-the-art equipment and methods for bioacoustic recording and analyses. We sum up with a step-by-step key on how to proceed in bioacoustic inventories and research.

Creating a Logo

...is easy with scratchpad technology, in terms of uploading a new picture. At present we are mainly AMibio team members,

so we could use some elements of our Amibio logo for the scratchpad Logo. But the scratchpad should link us with the rest of the bioacoustic community, so let´s think of a more general bioacoustic diversity logo.

Suggestions welcome! Greetings Klaus Riede

Some citations

Edited by Klaus Riede on Thu, 07/01/2010 - 17:10

As a first finger exercise in adding content to our site, I uploaded my citeulike bibliography into the biblio content section, certainly not quite focussed exlusively on bioacoustics and automatic signal recognition. May be we can cooperate to create an improved bibliography, using http:www.citeulike.org. I am using amibio as a tag for citations relevant for Amibio, else bioacoustics, conservation and ASR (automatic signal recognition). Please participate!

Kick-off meetings for all European LIFE+ Nature & Biodiversity projects

Submitted by Klaus Riede on Thu, 06/24/2010 - 10:49

In the first quarter of 2010, kickoff meetings and presentations of the newly starting LIFE+ Nature & Biodiversity projects* (funded under the 2008 campaign) took place all over Europe.

Greetings to the new users

Greetings to all new users! I must admit that I have to get acquainted with this new tool. Probably the first thing we need is add species lists and Phylogeny, together with forum topics and content. right now I am sort of handicapped, doing filed work in Panama, maily cricket recordings. In any case I will try to upload some sound files from the rainforest here.

With best wishes for a fruitful cooperation, yours Klaus Riede
