Revealing the hidden lives of cryptic mountain lions using GPS data and a Moving-Resting Motion model

Female mountain lion collared in Washington USA in late December 2021.

Information on how and even why terrestrial mammals move through their habitat landscapes is important for forming the foundation of how to manage and conserve species. For elusive mountain lions, GPS data is particularly vital for monitoring these important apex predators in relation to their ecosystems and the people they share the land with. In this blog post, the team discusses their novel motion model, published in Methods in Ecology and Evolution, which helps us understand the movement of mountain lions from GPS location data.

Policy on Publishing Code Virtual Issue

In January 2018, Methods in Ecology and Evolution launched a Policy on Publishing Code. The main objective of this policy is to make sure that high quality code is readily available to our readers. set out four key principles to help achieve this, as well as explaining what code outputs we publish, giving some examples of things that make it easier to review code, and giving some advice on how to store code once it’s been published.

To help people to understand how to meet the guidelines and principles of the new policy, a group of our Applications Associate Editors (Nick Golding, Sarah Goslee, Tim Poisot and Samantha Price) have put together a Virtual Issue of Applications articles published over the past couple of years that have followed at least one aspect of the guidelines particularly well.

moveHMM: An Interview with Théo Michelot

David Warton (University of New South Wales) interviews Théo Michelot (University of Sheffield) about an article on his recent R package moveHMM in Methods in Ecology and Evolution. David and Théo also discuss the case study in the paper – on the understudied wild haggis – and what advances could be made to the package in future.

Spatially-explicit Power Analysis: A First Step for Occupancy-Based Monitoring

The seemingly basic question of whether a population is increasing, decreasing, or stable can be one of the most difficult to answer. Collecting data on rare and elusive species is hard. Imagine trying to detect a handful of fisher or wolverine across hundreds of thousands of acres – it is physically demanding, time consuming and logistically complicated. And that’s just to do it once! To monitor a population for changes, you have to repeat these surveys regularly over many years. The long-term monitoring that is necessary for conservation requires careful planning and a substantial commitment of resources and funding. So before we spend these valuable resources, it’s critical to know whether the data we are collecting can help us to answer our questions.
