Issue 8.2

Issue 8.2 is now online!

The February issue of Methods is now online!

This issue contains four(!) Applications articles and two Open Access articles. These six papers are freely available to everyone – no subscription required.

 Earth Mover’s Distance: The Earth Mover’s Distance (or EMD) is a method commonly used in image retrieval applications. The authors of this paper propose its use to calculate similarity in space use in the framework of movement ecology. This will be helpful for many questions regarding behavioural ecology, wildlife management and conservation.

 warbleR: The R package warbleR is a new package for the analysis of animal acoustic signal structure. It offers functions for downloading avian vocalisations from the open-access online repository Xeno-Canto, displaying the geographic extent of the recordings, manipulating sound files, detecting acoustic signals or importing detected signals from other software, and much more.

– meteR: The open-source R package, meteR directly calculates all of Maximum entropy theory of ecology’s (METE’s) predictions from a variety of data formats; automatically handles approximations and other technical details; and provides high-level plotting and model comparison functions to explore and interrogate models.

– Noise Egg: The Noise Egg is a device that can produce a low-frequency sound, which can be used as an experimental source of noise both in aquaria and in the field. It was developed to study the effects of noise on communication and behaviour in small aquatic animals; however, it could be used for other purposes, such as testing the propagation of certain frequencies in shallow-water habitats.

Joint Species Distribution Models to Study Species and their Interactions

David Warton (University of New South Wales) interviews Otso Ovaskainen (University of Helsinki) about his two recent articles in Methods in Ecology and Evolution. David and Otso talk about studying communities of species and their interactions via joint species distribution models, the advances made by Otso’s papers and future developments in this field.

A new tool based on microbial interactions to analyze bipartite networks

Below is a press release about the Methods paper ‘BiMat: a MATLAB package to facilitate the analysis of bipartite networks‘ taken from the Pompeu Fabra University.

The Georgia Institute of Technology has created, together with the Pompeu Fabra University and the University of Canterbury, a new open-access and open-source tool for the study of bipartite networks

The team led by Joshua S. Weitz, Associate Professor at the School of Biology from the Georgia Institute of Technology, has developed BiMat: an open source MATLAB® package for the study of the structure of bipartite ecological networks inspired by real problems in microbiology and with broader applications. Cesar O. Flores, researcher at the School of Physics of the same institute, describes this new tool in an article published in the journal Methods in Ecology and Evolution. Sergi Valverde, Visiting Professor at the Complex Systems Lab from the Pompeu Fabra University, and Timothée Poisot, from the School of Biological Sciences of the University of Canterbury, are involved in the project.
