Scientific understanding is constructed, developed and advanced through open sharing of knowledge generated by scientists worldwide. Yet for years that collective knowledge has only been accessible to those who pay exorbitant amounts of money. Now the pressure is building for publishers to change the system, as more and more scientific communities push to bypass or break down the expensive paywalls that restrict access to global scientific progress.
Citizen Science and Biodiversity: Thoughts From a Meeting With the European Citizen Science Association

A collection of biodiversity researchers from across Europe came together in Brussels for a unique kind of meeting last week. We were connected by two common threads: first, we are all supported by BiodivERsA, a large network of European biodiversity research projects funded by the European Union’s Horizon 2020 program. And second, most importantly, we are all interested in connecting our biodiversity research with citizen science in one form or another.
The last three years have seen some serious political upheaval in the European region, Brexit being perhaps the pinnacle of that. It’s an issue on which everyone has an opinion and which no one seems to have any answers to. So I thought that this week I’d try to put together a synthesis of sorts on how Brexit will possibly affect the ecological science community. Below are a series of links to articles that describe the affect of Brexit on, and responses by, the ecological community.
Community, or citizen, science is a huge, often untapped data source for ecologists. So what are the pitfalls of using it? (Image Credit: Jacob W. Frank, CC BY 2.0)

Species distributions maps are great. I remember rifling through animal encyclopedias as a kid, checking out the distributions of my favourite animals, just assuming that people knew exactly where to find all these organisms. But the reality is that figuring out exactly where species live is extremely difficult.
It’s made easier, however, by the use of citizen (or community) science. This occurs when volunteers involve themselves in projects in which they observe and report the presence or absence of a species in a given area, which is then used to determine a species’ distribution. This data is obviously incredibly useful to any ecologist, but it comes with some drawbacks. This paper attempts to summarise those drawbacks and outline ways to work around them.
Fields full of herbaceous plants such as these can be incredibly diverse and complicated ecosystems, and the multitudes of species that inhabit them can influence the magnitude of disease that the organisms that inhabit it may encounter (Image Credit: LudwigSebastianMicheler , CC BY-SA 4.0)

Everything in ecology is based around the environment that a focal organism inhabits, including the interactions it has with other organisms and the non-living aspects of the habitat itself (temperature, water pH, etc.). That being said, it’s no surprise that disease dynamics are likely to depend on the environment that a host inhabits, and that the environment itself is a product of what came before. That is to say, the group of organisms that originally populate a given ecosystem can have an effect on how that ecosystem will look in the future (lakes with freshwater mussels will have clearer water than those without).
The scientific literature is full of experiments, observations, and hypotheses about which environmental conditions lead to fluctuations in disease dynamics. As such, it is difficult to come to a consensus with a “one-size-fits-all” rule for disease dynamics and community structure. The authors of today’s study used a long-term experiment to determine what exactly moderates disease over time. Read more
Charismatic species like the bottlenose dolphin are generally easier to find funding for. So what’s it like to work with them as a scientist. I spoke to evolutionary biologist Celine Frere to find out (Image Credit: Jason Pratt, CC BY 2.0)
