Factsheets sur deux espèces envahissantes au Gabon

By -
En dehors de la perte d'habitat, les espèces envahissantes constituent la plus grande menace pour la biodiversité mondiale. Deux des pires espèces envahissantes au monde sont établis au Gabon: la petite fourmi de feu (Wasmannia auropunctata) et la jacinthe d'eau (Eicchornia crassipes).
Ces deux espèces sont connues pour avoir des effets écologiques dévastateurs partout où ils s’établissent, et leur présence est confirmée dans plusieurs Parcs Nationaux du Gabon. En outre, comme nous n'avons pas encore mise en place des stratégies de gestion et de contrôle, le nombre de sites infestés augmente chaque année.
Il est essentiel que les parcs nationaux surveillent la distribution et la propagation de ces espèces, afin d'identifier les sites les plus à risque et intervenir dès qu'une nouvelle infestation est détectée.
Ces fiches ont été créées par l’ANPN pour nous aider à identifier W.auropunctata et E.crassipes et de prendre des mesures pour éviter sa propagation et de protéger nos milieux naturels. N'hésitez pas à partager ces fiches, et envoyez-nous vos informations en utilisant les coordonnées indiquées.

  Length-weight relationships of 13 fish species from Akanda National Park in Gabon, Central Africa English This study provides the length-weight relationships (LWRs) for 13 fish species belonging to 10 families. Samples were collected in the mangrove area of Akanda National Park (ANP) in Gabon between May 2017 and March 2018 with fishing trammel gillnets (15 m long and 1.10 m high, 100 mm large mesh outer layers, and one 10, 27, and 40 mm small mesh each net). Fish total length and total weight were measured, with the precision of 1 mm and 1 g, respectively. The LWRs parameters for the 13 fish species had not yet been reported in FishBase for Central Africa. Our study provides large size ranges for  Monodactylus sebae  and  Pseudotolithus senegalensis  LWRs for Central Africa. The determination coefficient (r²) between total length and total body weight ranged from 0.946 ( Pellonula leonensis ) to 0.999 ( Pseudotolithus senegalensi...

The Plateaux Batéké National Park now boasts four cat species, thanks to the return of the lion to Gabon

English Since the return of a single male lion to Gabon’s Plateaux Batéké National Park, this park now harbours four species of wild felids; more than any other park within Central Africa’s Congo Basin. Besides the lion ( Panthera leo ), the park is home to important populations of leopards ( Panthera pardus ), African golden cats ( Caracal aurata ), and Gabon’s only protected population of the serval ( Caracal serval ). Servals are open habitat specialists which mainly feed on small rodents. The species is most easily recognized by its long legs, short tail and large, rounded ears. Commonly, the medium-sized serval is boldly spotted black on a tawny underground. There are also melanistic individuals in certain areas, which appear completely black. Even rarer, is the so-called ‘servaline’ form, which has much smaller, freckled spots, and was once thought to be a separate species. All three forms have been filmed in and around Plateaux Batéké National Park, making this the only ...

Characterization of Beach Seine Fishing in the Mandji-Etimboué Aquatic Reserve (Gabon) Caractérisation de la pêche à la senne de plage dans la Réserve Aquatique de Mandji-Etimboué (Gabon) Abstract / Résumé EN – The conservation of marine biodiversity and the establishment of aquatic protected areas have become a global challenge. Thus, the continued use of non-selective fishing gear requires a comprehensive and ongoing assessment. With this in mind, the catch rates and socio-economic aspects of beach seine fishing in the Mandji-Etimboué Aquatic Reserve (AR) were examined using landing monitoring as a methodological approach. The results showed that the average catch per unit effort (CPUE) of beach purse seiners is 393.29 kg/seine haul . Comparative analysis between CPUE in 2017 and 2021 showed a decrease of 490.9 kg/fishing trip in the rainy season and an increase of 5.08 kg/fishing trip in the dry season. The decrease in fishing effort and increase in CPUE in this Mandji-Etimb...
