The Evolution of Naturalists: From Darwin’s Beagle to Digital Discoveries

As I prepare for my upcoming voyage on MS Spitsbergen, a journey from Bergen, Norway, along the Atlantic coast down to West Africa, exploring Cabo Verde and the Bijagos archipelago, I can’t help but reflect on the greatest voyages of exploration, one that not only defined my field of study but also shook the world’s beliefs to their core. Admittedly, it feels like I’m a bit late to the party once again.

The world has undergone seismic shifts since Charles Darwin set sail on the HMS Beagle in 1831. His voyage would ultimately reshape our scientific understanding, but it also marked the twilight of the old naturalists, ushering in a new era of biological exploration. In today’s modern world, where information flows like a river, our approach to exploring and understanding nature has transformed profoundly.

Similar to the evolution of Darwin’s finches, natural selection has led to the speciation of anole lizards adapted perfectly to the different islands in the Caribbean.

Paradigm Shifts

Once upon a time, the great explorers and naturalists of the Age of Enlightenment embarked on daring expeditions into uncharted territories. Armed with boundless curiosity, unwavering spirit, and an insatiable thirst for the unknown, these pioneers were not just observers of nature’s wonders; they were the architects of scientific discovery.

However, as the world raced forward, it seemed to shrink in some inexplicable way. The unrelenting pace of life quickened, and the old naturalists, once a thriving breed, found themselves struggling to keep pace with the rapidly changing landscape of scientific exploration. The era of the solitary observer, who meticulously recorded every intricate detail based on a lifetime of experience, was slowly giving way to a new paradigm.

Here and now, we find ourselves in the age of the new naturalists—modern explorers armed with smartphones, cameras, and an unquenchable curiosity. They aren’t satisfied with passive consumption of information; they actively engage with the natural world.

In our digital age, technology plays a pivotal role, both challenging and empowering these hobby naturalists. With their devices in hand, they not only capture the breathtaking beauty of nature but also document its phenomena, sharing their discoveries passionately with a global audience.

Amidst this flood of data from digital naturalists, one question looms large: How do we manage this deluge of information? Here’s where technology’s magic comes into play. It transforms this torrent of data into structured, standardized information—a treasure trove of knowledge. This vast pool of data, meticulously gathered by enthusiasts worldwide, underpins cutting-edge scientific research.

Tackling the Unknown

Since its launch in 2008, iNaturalist has stood at the forefront of this digital revolution in naturalism. Much like the computer vision model identifying species from images, iNaturalist now introduces the Geomodel—a marvel of deep learning. Unlike its visual counterpart, the Geomodel takes geographic locations as inputs and predicts the most likely species inhabiting those areas.

The Geomodel’s uniqueness lies in its ability to harness collective observations. It leverages a global community of naturalists, each armed with a smartphone and a keen eye for nature, to predict species’ presence in specific locations—a testament to the powerful synergy between citizen science and cutting-edge technology.

But where does the Geomodel fit into the broader context of biodiversity knowledge? It tackles one of the seven shortfalls that have plagued our understanding of biodiversity, as highlighted in the publication “Seven Shortfalls that Beset Large-Scale Knowledge of Biodiversity” [Hortal et al. 2015]. Specifically, the Geomodel makes significant strides in mitigating the “Wallacean shortfall of knowledge,” addressing the challenge of accurately predicting the geographical distribution of many species.

The Geomodel goes beyond mere species identification. It enhances the accuracy of computer vision suggestions, transitioning from grid-based observations to a future where geospatial information is fast and accessible. This means that mobile apps can now offer in-camera suggestions and display taxon maps offline, liberating nature enthusiasts from the constraints of a constant internet connection.

The significance of the Geomodel extends further—it serves as a tool to spotlight unusual observations. In an ever-evolving natural world, these peculiar sightings could signify misidentifications or groundbreaking discoveries—a potential new species, an extended range, or the early detection of an invasive species. The Geomodel’s ability to rank observations by their geographic uniqueness promises to deepen our understanding of the natural world.

In the realm of conservation, the Geomodel provides a potent instrument for assessing the geographic range size of species—a critical factor in conservation efforts. It empowers land managers to allocate resources and attention, focusing on small-range species facing a higher risk of extinction.

In the age of the sixth mass extinction, where biodiversity teeters on the brink, the recording and study of nature’s intricacies assume paramount importance. As species vanish before our eyes, each data point recorded by new naturalists contributes to a broader understanding of ecosystems and informs critical decisions about conservation efforts.

Embracing the era of the new naturalists involves acknowledging the pivotal role of technology in reshaping the field. The Geomodel, a living embodiment of this transformation, bridges the gap between citizen science and data-driven insights. It empowers individuals to connect with nature, contribute valuable data, and collectively unveil the mysteries of our ever-changing world.

The old Naturalists are dead – Long live the modern Naturalists?

“Freedom of thought is best promoted by the gradual illumination of men’s minds, which follows from the advance of science.”

Charles Darwin

In true Darwinian spirit, it’s essential to exercise caution when wielding such powerful tools. Just as Darwin meticulously weighed the implications of his groundbreaking theory of evolution by natural selection, we must consider the consequences of our digital discoveries. The profound nature of these revelations has the potential to reshape our understanding of the natural world and our interactions with it.

Darwin would likely view these developments as valuable for advancing our understanding of biodiversity and natural history, as he advocated using the best available tools for scientific research. He would appreciate the ability of iNaturalist and other citizen science initiatives to engage a broad community of observers and promote the study of the natural world, aligning with his passion for exploration and scientific inquiry. Darwin would also recognize that iNaturalist, like any scientific endeavour, has limitations and challenges, including data quality, biases in observation, and the need for expert validation of identifications.

And so, we stride forward into an era where, in the footsteps of the old naturalists and equipped with a passion for nature, anyone can make a difference, irrespective of their background, but always mindful of the profound implications of their discoveries.


How about hunting species instead of eggs this Easter?

Yes, I’ll admit that I am late to the party.

A number of posts and articles about citizen science apps and species recording have popped up over the last years, and in fact, I myself, referenced various for my Master’s thesis. Because of that, I also have been aware of the poor data availability, that makes it hard to predict the geographical distribution of many species – also known as the Wallacean shortfall of knowledge [Hortal et al. 2015].

So why talk about this now?

I recently upgraded my camera system to a second hand Nikon D7000 with a Sigma 100-400mm F5-6,3 DG OS HSM lens. My trip to South Africa taught me the value of a photographing nature with a  DSLR with a nice telezoom lens and now here I am, back home, testing out the new camera system.

This is all fun and some photos probably end up on my Instagram, but for the vast majority, I did not have a purpose – at least until now. As a biologist, taking photos is the one thing, IDing what’s on them is the other. I had downloaded some German fauna identification apps over the last two days, but they seemed to include only incomplete species lists.

I don’t remember exactly the trigger, it must have been some tweet or similar, but yesterday finally, I decided to download the iNaturalist app and I am delighted!

What’s so amazing about iNaturalist?

Forget about the biologist, my inner-geek instantly fell in love!

1. Easy GUI and SpeciesID: iNaturalist allows you to add your photos and will extract metadata directly – this means: no inserting of space or time (as long as your photos are already geotagged). Furthermore, based on your photo (and location?), algorithms will suggest you the taxon or genus name of the species you photographed. If you don’t have any idea, this is definitely a neat starting point.

2. Community and Data validation: Just because you identify something, does not make it a valid record. The community got you and will verify or improve your identification.

3. Open Data: iNaturalist reports its citizen science records to the Global Biodiversity Information Facility (GBIF) – this means the recorded data is not lost, and everyone can access and analyse it!

4. Gamification:  Remember Pokemon Go!? Well, turns out during prime time of usage, it took their users around a week to find as many Pokemon, as there are overall species records on GBIF.

#PokemonGo players could capture entire data holdings of @GBIF in 6 days. https://t.co/ymek2dreQh @rdmpage pic.twitter.com/TqXxS9TTyP

iNaturalist includes gamification to get you out and searching for specific plants or animals, which certainly can make the whole thing more competitive and fun.

5. The API: Want the possibility to access your own data to for example provide a heat map with all your records? No problem!

To sum all of this up

iNaturalist is a citizen science app, that allows you to record species occurrences. Compared to other apps on the market (especially the ones offered in Germany) it does provide the option of monitoring internationally with an underlying holistic species list and a community that got you covered. Their community validation system ensures a quality rating for all the records and this makes it valuable for inclusion in open databases like GBIF.

I highly suggest you test the app, which is celebrating it’s 10th anniversary this year, especially if you enjoy nature photography, just like me and would like to work for a good cause. In many regions, we’re still lacking a proper knowledge about the distribution of species and this is one easy chance to contribute while improving your ID skills.
