About the issue

Issue 3.3 contains an amazing number of extra features: three videos, one podcast and one Powerpoint presentation. The topics in the issue range from DNA barcoding, surveys, measuring diversity, population and movement modelling and includes five free applications.

About the cover

Recently developed light-weighed tracking devices for positioning through light intensity pattern (‘geolocation’) have begun to greatly improve our knowledge of animal migration. However, the analysis of geolocator data is impeded by many factors potentially affecting light levels and thus, ultimately the determination of positions. Herein, weather and vegetation are major factors altering the light regime experienced by the animals. The picture shows a Common Rosefinch (Carpodactus erythrinus) featured with a 0.5 gram geolocator device.

In Geolocation by light: accuracy and precision affected by environmental factors Simeon Lisovski and colleagues demonstrated the effect of weather, topography and vegetation on the measurement of day/night length, time of solar midnight/noon and the resulting position estimates using light measurements from stationary geolocators at known places and from geolocators mounted on birds.

  1. Very nice blog! I’m currently preparing a manuscript that we’re hoping to submit to MEE in the next month or so, and after having spent the last half hour perusing interesting discussions and articles (instead of working on that paper…) that are close to my interests, I’m pretty convinced that we picked a good journal to aim for. Keep up the good work!
