The first issue of 2014 is now online, and is freely available – enjoy!
This month we have included articles on estimating extinction rates, demographics, missing data, networks, and large-scale experiments. There are 2 open access articles: Using time-to-event analysis to complement hierarchical methods when assessing determinants of photographic detectability during camera trapping by Richard Bischof et al., and Designing forest biodiversity experiments: general considerations illustrated by a new large experiment in subtropical China by Helge Bruelheide et al., along with an application article: A method for detecting modules in quantitative bipartite networks, by Carsten F. Dormann and Rouven Strauss.
About the cover: Camera trapping has become an important tool for ecological study, especially when working with elusive species in remote areas. This issue’s cover image shows a series of photos of snow leopards collected by the authors with camera traps in the mountains of northern Pakistan in 2011 and 2012. Each row of images is a separate sequence, captured at a different site. The data from camera trapping – evidence of an organism in space and time – are a result of the ecological process of presence vs. absence and the observation process of detection vs. non-detection. The article associated with the image, Using time-to-event analysis to complement hierarchical methods when assessing determinants of photographic detectability during camera trapping, demonstrates how hierarchical analytical methods, in combination with time-to-event statistics, can yield valuable insights into how photographic evidence accumulates during camera trapping. The Norwegian University of Life Sciences published a press release about this article, entitled ‘Spying on snow leopards’.
