Whereas scientists interested in subterranean life typically insist that their research is exciting, adventurous, and important to answer general questions, this enthusiasm and potential often fade when the results are translated into scientific publications. This is because cave research is often written by cave scientists for cave scientists; thus, it rarely “leaves the cave”. However, the status quo is changing rapidly. We analysed 21,486 articles focused on subterranean ecosystems published over the last three decades and observed a recent, near-exponential increase in their annual citations and impact factor. Cave research is now more often published in non-specialized journals, thanks to a number of authors who are exploiting subterranean habitats as model systems for addressing important scientific questions. Encouraged by this positive trend, we here propose a few personal ideas for improving the generality of subterranean literature, including tips for framing broadly scoped research and making it accessible to a general audience, even when published in cave-specialized journals. Hopefully, this small contribution will succeed in condensing and broadcasting even further the collective effort taken by the subterranean biology community to bring their research “outside the cave”.

Whether it is about birds or bugs, ants or antelopes, and no matter their ecology, systematics, or sexual behaviour, natural scientists tend to fall in love with the systems they study. This is nothing surprising considering how subtle and complex some eco-evolutionary patterns are, demanding the personal involvement of those seeking to unravel them. As this engagement increases, the distinction between work and passion often fades, promoting the idea of the stereotypical Stakhanovist scientist working tirelessly in the lab without realizing that the hours pass by. This hardworking attitude has blinded many scientists to the point of prioritizing their career over personal development and time with friends and family (
Since most natural scientists share this very same passion for the natural world, how to explain the uneven impact of their research as individuals (
Selecting a natural organism or system might be seen as a trade-off between subjective features making it appealing to study (aesthetic characteristics, peculiar adaptations, etc.) and objective features making it a good model (ease to raise in the lab, generation time, genome size, etc.). And since many of these features are not obvious when selecting a new model organism (
Have subterranean biologists picked a tasty chocolate too? There are plenty of arguments suggesting that caves are amongst the appealing model systems (
At some point, human curiosity took this ancestral fascination one step further. This is how geologists turned anthropomorphic rocks into speleothems, taxonomists renamed puppet-dragons as Proteus anguinus (
However, this status quo is changing. Over the last decade or so, we have witnessed how more and more cave-based research resonates outside our specialized community. To show this, we here analysed the citations and impact factor of articles focusing on subterranean ecosystems, using a database of 21,486 research articles published between 1991 and 2019 (full details on data collection are in

Variations in citations over time in papers focused on subterranean systems published in specialized journals. The average ± standard error number of Web of Science citations is based on a subset of articles published in Acta Carsologica, International Journal of Speleology, Journal of Cave and Karst Studies, and Subterranean biology (n= 969). Note that prior to 2005, no data was available for these journals in Web of Science.
A quick scrutiny of these highly cited papers shows that most of them used caves as systems to address general questions. The peculiarities of caves as simplified model systems in ecology and evolution have been summarized elsewhere (
Notably, darkness, isolation, and weirdness–the properties that constitute caves as excellent models to address timely questions in modern science–were also those that amazed our ancestors, symbolically rooting caves deeply in our human nature as a representation of our myths, tales, and pop-culture memes (Campbell 1956;
Encouraged by the inherent peculiarities of caves, we might have forgotten the importance of trying to address broad questions with our research, favouring the isolation of our research community and increasing our intellectual inbreeding. We believe that being aware of this potential is a fundamental step to frame broad-in-scope subterranean research (
1. Try to identify general questions that are scalable to other systems ( 2. Read and cite as many non-cave papers as possible. We say, baby, take a walk on the bright side. 3. It is advantageous to collaborate with non-cave scientists. They might even come up with good ideas... 4. Make your text understandable to a general audience ( 5. Don’t overemphasize your findings with superlatives and exaggerations ( 6. When discussing the importance of your findings, don’t appeal to authority. We say so. 7. Don’t be jealous: data-sharing only brings you benefits ( 8. And, well, don’t forget to come back to good old cave literature from time to time. There is still a lot of wisdom in the Rock Art of our ancestors. |

A.M. did the search on the Web of Science. S.M. plotted the graphs. Then, the idea came along, and both authors wrote and approved the text together.
