China’s energy transition has been taking place since 2010, alongside an economic transition. The links between these two processes are studied here, using a Lewisian framework of structural change. China’s development model up until 2010 caused significant environmental damage, but it also created an economic context that would eventually favor the first steps of its ambitious energy transition, by absorbing the rural labor surplus. This absorption is a necessary condition for the success of the energy transition, but it is not enough on its own.; La transition énergétique chinoise s'opère depuis 2010 sur un fond de transition économique. La relation entre ces deux processus est appréhendée ici par un cadre d’analyse de changement structurel à la Lewis. Le mode de développement mis en œuvre par la Chine jusqu’à la fin des années 2000 a certes été très impactant pour l’environnement, mais il a aussi mis en place des conditions favorables à une transition énergétique ambitieuse, en résorbant le surplus de travail agricole. Cette absorption constitue une condition nécessaire quoique non suffisante à la réussite du processus de transition.

Uncommon records of fishes may evidence local or global changes in fish composition resulting from environmental change or anthropogenic activities. Significant records of uncommon marine fishes, including migrant, non-native, cryptic, rare and threatened species, collected in French waters or by French vessels in European waters, observed by scuba divers or beachgoers, are reported for the year 2018. They include first, new, rare and unusual records for the following 52 species: Hexanchus griseus, Squatina squatina, Gymnura altavela, Acipenser sturio, A. gueldenstaedtii, Dalophis imberbis, Nemichthys curvirostris, Eurypharynx pelecanoides, Maulisia mauli, M. microlepis, Sagamichthys schnakenbecki, Melanostomias bartonbeani, Astronesthes niger*, Leptostomias gladiator*, Chlorophthalmus agassizi, Magnisudis atlantica, Evermannella balbo, Regalecus glesne, Luvarus imperialis, Raniceps raninus, Fistularia cf. petimba*, Trigla lyra, Lepidotrigla dieuzeidei, Micrenophrys lilljeborgii, Howella atlantica*, Pomatomus saltatrix, Serranus cabrilla, Caranx crysos, Seriola rivoliana, Trachinotus ovatus, Lobotes surinamensis, Sarpa salpa, Chelon ramada, Pseudoscopelus altipinnis*, Trachinus draco, Parablennius pilicornis, P. ruber, Buenia affinis, B. jeffreysii, Chromogobius zebratus, Didogobius splechtnai, Gammogobius steinitzi, Gobius couchi, G. kolombatovici, Lebetus sp., Speleogobius trigloides, Thorogobius macrolepis, Vanneaugobius dollfusi, Siganus rivulatus*, Lepidocybium flavobrunneum, Hyperoglyphe sp. et Pegusa cf. nasuta, among which six, marked with an asterisk (*), represent additions to the Checklist of the marine fishes from metropolitan France and one, N. curvirostris, is a first record for the Mediterranean.
