10 Great SciComm Twitter Games To Brighten Your Quarantine

This month, in line with Global Citizen Science Month, we’ll have a special focus on all things citizen science. For those of you who are unaware of the concept, it’s an initiative by SciStarter and the School for the Future of Innovation in Society at Arizona State University, with support from the Citizen Science Association and National Geographic.

For those who haven’t heard the term before, citizen (or community) science is essentially an all-encompassing term for scientific research and learning that is conducted outside of traditional spheres. It can encompass anything, from your kid collecting bugs in traps in the backyard, to global apps like iNaturalist. While Caitlin will have an in-depth overview of exactly what citizen science entails next Monday, we’ll kick the month off by looking at revolutionary technology that has allowed non-scientists to participate in scientific research worldwide – social media.

Specifically Twitter. One of the most enjoyable things about Twitter’s scientific community has been the advent of SciComm games. These are (often weekly) posts by scientists from different fields, which ask fellow Twittererers to identify, find or pick apart different aspects of an ecosystem. They’re a great introduction to taxonomy and field identification, and they’re super-easy to get involved in.

So below I’ve listed (with the help of Twitter) 10 of the most fun Twitter games out there.

Mermaid Sex, Evil Spirit Birds and More Weird Ecology Search Terms

We get a lot of fun and strange search terms which lead people to Ecology for the Masses. So inspired by Captain Awkward’s segment ‘It Came From the Search Terms‘, let’s have a look at some of the weirder questions that led people to this site and see if we can provide some answers. Spelling mistakes have been corrected.

What’s the Deal with P-Values and Their Friend the Confidence Interval?

After the first edition of Ecology for the Masses’ new Stats Corner, many people requested a discussion of p-values. Ask and you shall receive! And as an added bonus, we’ll also talk about confidence intervals. (Image Credit: Patrick Kavanagh, CC BY 2.0, Image Cropped)

Much of ecological research involves making a decision. Does implementing a particular management strategy significantly increase the species diversity of a region? Is the amount of tree cover significantly associated with the number of deer? Do bigger individuals of a species tend to have longer life expectancies?

Worrying Trends in North America’s Bird Populations

Decline of the North American avifauna (2019) Rosenberg et al., Science, DOI: 10.1126/science.aaw1313

The Crux

When we talk about species loss, we generally focus on extinctions. Too often, when we start to rally around a species, it’s because there are a particularly low number of that species left. In many cases, they’ve often crossed a threshold, from which it’s impossible to pull them back from the brink of extinction.

Often this draws attention away from non-threatened species. Often that’s fine – they’re non-threatened right? But downward population trajectories in these species can still damage ecosystems by lessening the impact of their ecological function, lead to local (if not total) extinctions, and of course, leading them to eventually be threatened.

This week’s authors wanted to look at bird population declines in America, but from the perspective of total abundance, as opposed to a more species-specific view.

Water-Based Recreation Can Promote Non-Native Introductions

Invasion of freshwater ecosystems is promoted by network connectivity to hotspots of human activity (2019) Chapman et al., Global Ecology and Biogeography, https://doi.org/10.1111/geb.13051

The Crux

The spread of invasive species throughout freshwater ecosystems is a topic we’ve looked at before on Ecology for the Masses. In a previous paper breakdown we talked about how recreational is heavily responsible for the presence of non-native fish at a European scale.

Our paper this week takes a more local approach. Can we predict the presence of non-native birds, invertebrates and fish by looking at the presence of human activity, and where that human activity is present?

Jane Reid: Playing the Ecological Long Game

Our world is changing rapidly. Yet our perception of just how much it has changed is often dulled by our inability to compare what we see around us to what was around fifty years ago with enough clarity. This is one of the reasons that long-term scientific studies are so important. They give us a tangible assessment of just how much our world has changed, whether that be in the climate, how species have evolved, our how populations fluctuate.

Jane Reid is the new International Chair Professor at the Department of Biology at the Norwegian University of Science and Technology. Jane has spent years working with several long-term studies, some of them successful, others not so much. Sam Perrin and I spoke to Jane about the importance of long term studies in ecological science.

It’s Not How You Get There, But When

When migrating, animals like the great white pelican have to walk the fine line between saving time and saving energy. (Image Credit: Ray in ManilaCC BY 2.0, Image Cropped).

Landscape-dependent time versus energy optimisations in pelicans migrating through a large ecological barrier (2019) Efrat et al., Functional Ecology, https://dx.doi.org/10.1111/1365-2435.13426

The Crux

We have all seen the amazing scenes in nature documentaries of the great seasonal migrations undertaken by many different species on this planet. By migrating between two different habitats, migrating animals are thought to maximize both how many resources they have access to, and to minimize their exposure to harsh environmental conditions.

Despite these benefits gained by migrating animals, there are risks associated with these seasonal, long-distance travel events. Migrating animals, like the great white pelican (Pelecanus onocrotalus), have to decide what is better: traveling for a shorter distance or using less energy by taking a less strenuous – but longer – path. Today’s authors tracked the great white pelican during its seasonal migration over the Sahara to study how these birds made decisions about their travel.
