Researchers at Washington State University and Smith-Root recently invented an environmental DNA (eDNA) filter housing that automatically preserves captured eDNA by desiccation. This eliminates the need for filter handling in the field and/or liquid DNA preservatives. The new material is also biodegradable, helping to reduce long-lasting plastic waste associated with eDNA sampling.
This video explains their new innovation in the field of eDNA sampling technology:
We’ve got six papers that are freely available to absolutely everyone this month too. You can find out about two of the Open Access papers in the Applications and Practical Tools section below. In the third, Chen et al. show that tree assemblages in tropical forest ecosystems can present a strong signal of extensive distributional interspersion.
Methods in Ecology and Evolution is a journal, so naturally we’re obliged to take journal point of view. Which means we need to get really excited about how amazing impact factors are1. Even though we know we shouldn’t, we are really really excited to say that our impact factor for 2018 is…
Last year it was a lowly 6.3. This increase is great, especially as we are still in the top 10 of Ecology journals (at no. 9, having risen to be a massive 0.05 above Molecular Ecology Resources). If we were listed in Evolution, we would be at number 7. And if we were a biology journal, we would be at number 5. There’s evidently not a lot of biology going on nowadays.
It’s more important than ever for us to have accurate information to help marine conservation efforts. Jordan Goetze and his colleagues have provided the first comprehensive guide for researchers using diver operated stereo-video methods (or stereo-DOVs) to survey fish assemblages and their associated habitat.
But what is Stereo DOV? What makes it a better method than the traditional UVC (Underwater Visual Census) method? And when should you use it? Find out in this video:
Plant-pollinator interactions are often considered to be the textbook example of co-evolution. But specialised interactions between plants and pollinators are the exception, not the rule. Plants tend to be visited by many different putative pollinator species, and pollinating insects tend to visit many plant hosts. This means that diffuse co-evolution is a much more likely driver of speciation in these communities. So, the standard phylogenetic methods for evaluating co-evolution aren’t applicable in most plant-pollinator interactions. Also, many plant-pollinator communities involve insect species for which we do not yet have fully resolved phylogenies. Continue reading →

Here at Methods in Ecology & Evolution and the Journal of Animal Ecology we are excited by the new directions that the next decade of research into animal social networks will bring. We hope to encourage new advances in the study of animal social networks by calling for high-quality papers for a cross-journal Special Feature on animal social networks. Below, Damien Farine and the Special Feature Guest Editors have reviewed some areas of animal social network research that deserve particular attention.
There are a wide variety of network metrics (node-based, dyadic, and global) and the application and development of new metrics continue to evolve. It is crucial to consider how the values generated by a network metrics (new and old) are interpreted biologically and recognize their limitations. It would be useful to have manuscripts that address questions about:
How mathematical definitions of different network metrics translate to biological processes;
Which metrics provide similar, redundant, or unique information relative to other metrics.
Quantifying animal movement is central to research spanning a variety of topics. It’s an important area of study for behavioural ecologists, evolutionary biologists, ecotoxicologists and many more. There are a lot of ways to track animals, but they’re often difficult, especially for people who don’t have a strong background in programming.
Vivek Hari Sridhar, Dominique G. Roche and Simon Gingins have developed a new, simple software to help with this though: Tracktor. This package provides researchers with a free, efficient, markerless video-based tracking solution to analyse animal movement of single individuals and groups.
Vivek and Simon explain the features and strengths of Tracktor in this new video:
It’s already been a busy 2019 for the six BES journal blogs. We’ve covered topics from leaving the nest to sustainable food production, stress in academia to climate change. On Relational Thinking we learned that cats can’t trespass. And Animal Ecology in Focus taught us that some crabs steal food from plants.
Today we’re having a look back at some of last month’s highlights from across the blogs:
Cats Can’t Trespass
This post was created by the author of one of our published papers. It’s a really creative and funny illustrated summary of their paper.
BES 2018: Field Notes from Birmingham
This post was written by our Associate Editor Andrea Belgrano and is his conference report on BES2018. It is an evocative and sensitive reflection on the meeting, where he compares the spiritual energy of the community to that of the Zen Buddhist Daruma Doll. Continue reading →
