Ecological Census Techniques

TL;DR: A global biodiversity monitoring network would develop a global sampling programme for indicator taxa and integrate regional sampling programmes for taxa that are locally relevant to the monitoring of biodiversity change and promote the development of comparable maps of global land cover at regular time intervals.

TL;DR: European carabids appear useful model organisms and possibly indicators because they are diverse, taxonomically and ecologically well-known, efficiently reflect biotic and abiotic conditions, are relevant at multiple spatial scales, and are easy to collect in sufficiently large numbers to allow statistical analyses.

TL;DR: Collaborative research by networks of amateurs has had a major role in ornithology and conservation science and will continue to do so as discussed by the authors, and the success of such work depends on the independence of the science from those advocating particular policies in order to ensure that the science is unbiased.

TL;DR: This work considers strategies to ease the implementation of distance sampling methods, to enhance their reliability, to adapt the methods for difficult species, and to deal with circumstances in which representative sampling is problematic.
