Simone: Taxonomic revision of the orthalicid land snails (Pulmonata: Stylommatophora) from Trindade Island, Brazil. The native flora of the island is now largely destroyed due to introduced goats, this again led to the extinction of all native (and non-native, except for two spp.) land snail species! It is suspected that this reduction in size reflects inappropriate environmental conditions due to the Island’s much degraded environment.” “ Curiously, the shell length of the adult specimens analysed by Breure and Coelho (1976) averaged from 8 to 9 mm (which was an overestimation, our measures of the same specimens average 7 mm), while the ones collected by the MD-55 and later expeditions average 4.8 mm the shell morphology, though, is the same. Bombus rubriventris LepeletierĪpparently, the species is known exclusively from empty shells, which differ greatly in their size depending on their collection date, foreshadowing the reasons for their final extinction.: This entry was posted in 6.Aves and tagged Brazil, Fernando de Noronha, Rallidae, Rallus, Rallus sp., Rallus sp. National Geographic Society Research Reports 13: 481-492. Olson: Natural history of vertebrates on the Brazilian islands of the mid South Atlantic. The form may have been a member of the genus Laterallus or Rallus, however, the species has still not been described. I have briefly alluded to this form elsewhere …, but it has yet to be formally described.” It does not appear to be particularly close morphologically to any of the species of rails from mainland Brazil. This was a medium- size rail with the wings reduced, but to a lesser extent than in many flightless species. ![]() Most of the elements of the skeleton, from several different individuals, are represented. “ Remains of a new species of rail (Rallidae) were also found, bringing the total known land-bird fauna to four species. The Fernando de Noronha Rail is an enigmatic bird known from subfossil remains that had been found in the late 1970s on the island of Fernando de Noronha, 354 km offshore the coast of Brazil.: ![]()
