Climate change is threatening biodiversity and ecosystems around the world. We urgently need to better understand how species and ecosystems respond to these changes. There are already thousands of climate change experiments and observational studies out there that could be used to synthesise findings across systems and regions. But it turns out that making meaningful syntheses isn‘t always so straightforward!
The Need for Standardised Methods and Reporting
There are two major challenges (and some minor ones too) for synthesising data across different experiments. First, the data are not always available. This problem arises because key study information – such as metadata, covariates or methodological details – are often not adequately or consistently reported across studies.
The second problem is that scientists use different protocols. This leads to a diversity of ways of measuring and quantifying the same variables. Different protocols may measure or report the same variables in slightly different ways, so the data are not compatible. Consistency in measurements and protocols is one reason why working in large networks – such as ITEX, Herbivory, or NutNet – to name only a few, is so powerful. In these networks, experiments and observations are repeated across large regions or worldwide using strict protocols for experimental design and measurements. Continue reading →
At a time when data is everywhere, and data science is being talked about as the future in different fields, a method that produces huge amounts of multimedia data is camera-trapping. We need ways to manage these kinds of media data efficiently. ViXeN is an attempt to do just that.
Camera traps have been a game-changer for ecological studies, especially those involving mammals in the wild. This has resulted in an increasing amount of camera trap datasets. However, the tools to manage camera trap data tend to be very specific and customised for images. They typically come with stringent data organisation requirements. There’s a growing amount of multimedia datasets and a lack of tools that can manage several types of media data.
In ‘ViXeN: An open‐source package for managing multimedia data’ we try to fix this visible gap. Camera trap management is a very specific a use-case. We thought that the field was missing general-purpose tools, capable of handling a variety of media data and formats, that were also free and open source. ViXeN was born from this idea. It stands for View eXtract aNnotate (media data). The name is also an ode to the canids I was studying at the time which included two species of foxes.
Earlier this month Leila Walker attended a panel discussion imparting ‘Practical Tips for Reproducible Research’, as part of the Annual Meeting of the Macroecology Special Interest Group(for an overview of the meeting as a whole check out this Storify). The session and subsequent drinks reception was sponsored by Methods in Ecology and Evolution. Here, Leila reports back on the advice offered by the panel members.
For anyone interested in viewing further resources from the session, please see here. Also, you may like to consider attending the best practice for code archiving workshop at the 2016 BES Annual Meeting. Do you have any tips for making your research reproducible? Comment on this post or email us and let us know!
This year’s Annual Meeting of the Macroecology SIG was the biggest yet, with around 75 attendees and even representation across the PhD, post-doc and faculty spectrum. The panel discussion aimed to consider what reproducibility means to different people, identify the reproducibility issues people struggle with, and ultimately provide practical tips and tools for how to achieve reproducible research. Each of the participants delivered a short piece offering their perspective on reproducibility, with plenty of opportunity for discussion during the session itself and in the poster and wine reception that followed.
