Late Quaternary warm marine mollusks from Santa Maria (Azores); paleoecologic and paleobiogeographic considerations

The sub-fossil fauna from the Late Quaternary marine deposits of Santa Maria is made of more than 50 species of gastropods and bivalves, 19 of them collected recently and for the first time in the northern coast of the island (Lagoinhas Bay). The sub-fossil shells are found in deposits of beach sands, situated 2-3 meters above the present low tide. The carbonated sands from the basal part of the succession yield an autochthonous association of borers dominated by the bivalve Myoforceps aristata (Dillwin, 1817). Upwards, the marine sands contain concentrations of beach drift shells, including well-preserved supratidal and intertidal gastropods, among them a large number of Rissoidae. The bivalve fauna is dominated by disarticulated valves of Ervilia castanea (Montagu, 1803), a small infaunal coloniser of mobile sandy substrates. The composition of the fauna is made essentially of West European species, many of them common to the West Coast of Portugal. However, a few "warm guests" with West African or Caribbean affinities were also found, suggesting a close relation with some of the "Tyrrhenian" warm associations found in the Western Mediterranean.

Orientalism and Imperialism in French West Africa. Considerations on travel literature, colonial tourism, and the desert as a “commodity” in Mauritania

In this article we intend to make a summary overview of the influence that literary production, originated under colonial mapping missions or later in travel writing, had in the construction and establishment of a discourse to advertise and promote tourism in Mauritania. To this end we will draw on travel narratives that are illustrative of different periods and that correspond in some way to discourses of otherness. In this specific case, such discourses relate to the “Moors” of the West African coast and were produced in various historical contexts. We will also consider the discourse present in the tourism promotion materials of the colonial period and we will demonstrate to what extent it can be engaged in a dialogue with 19th and 20th centuries’ Western colonial literature.
