The climate challenge of this century encourages to rethink our mobility. Planes and individual cars, very energy-consuming, are used for a great portion of very-long-distance travels (more than 750 km). In order to progress towards modal shift to more ecological modes, massive investments for rail have been made since the 2000’s. They have been mostly concentrated on High-Speed-Lines (LGV, in French) projects. But in spite of these huge investments, these projects did not reduce of the emissions of aviation, which keep growing in France. What’s more, it is becoming very complicated to finance the expansion of the LGV network, as the most relevant lines – between metropolises separated by 400 to 750 km – have already been built. And nowadays passengers tend to prefer cheaper tickets to faster journeys. Besides, an other rail solution for very long distances, the InterCity Night train (ICN) sees its dismantling accelerated in 2016-2017. As for the classical railway network and the daytime Intercity trains (ICJ for “InterCités de Jour”), they have suffered underinvestment during all these years. Neglected for the last decades, the ICN offer now has problems of visibility, unattractive timetables, and too frequent delays and cancellations: it seems that its use has been – willingly or not – discouraged. SNCF and the French State have kept repeating contradictory justifications around the “alleged deficit” and “empty” night trains, but they have high occupancy rates. The ICN has in fact quite many advantages

This tension between freedom and stability was long ago formalized in two sets of official and binding rules: the International Code of Zoological Nomenclature (ICZN), which deals with animals, and the International Code of Nomenclature for algae, fungi, and plants (ICN). Periodically updated by committees of working taxonomists, these documents set out precise, legalistic frameworks for how to apply names both to species and to higher taxa. (The animal and plant codes operate independently, which means that an animal can share a scientific name with a plant, but not with another animal, and vice versa.) While this freedom opens up a valuable space for amateur contributions, it also creates a massive loophole for unscrupulous, incompetent, or fringe characters to wreak havoc. That’s because the Principle of Priority binds all taxonomists into a complicated network of interdependence; just because a species description is wrong, poorly conceived, or otherwise inadequate, doesn’t mean that it isn’t a recognized part of taxonomic history. Whereas in physics, say, “unified theories” scrawled on napkins and mailed in unmarked envelopes end up in trashcans, biologists, regardless of their own opinions, are bound to reckon with the legacy of anyone publishing a new name. Taxonomists are more than welcome to deal with (or “revise”) these incorrect names in print, but they can’t really ignore them.
