Organochlorine Residues in Common Tern Eggs from Nine Atlantic Coast Colonies, 1980

This chapter considers how Wolof, an Atlantic language spoken in Senegal, has become an important lingua franca, and how French has contributed to the ascent of Wolof. The nature of social relations between Africans and French in cities along the Atlantic coast in the 18th and 19th centuries were such that a prestigious urban way of speaking Wolof that made liberal use of French borrowings became the language of the city. As an index of urban belonging, opportunity, and modernity, Wolof was viewed as a useful language, a trend that has continued up to the present. Four case studies illustrate how the use of Wolof facilitates mobility for speakers of other languages in Senegal. By drawing a distinction between the formal and informal language sectors, this chapter offers a more realistic view of everyday language practices in Senegal, where Wolof is the dominant language.

Coloration Patterns

The genus Orthopristis includes seven valid species, three from the western Atlantic and five from eastern Pacific, while the available identification guides and taxonomic keys incorrectly recognize Orthopristis ruber as the only valid species found on the Atlantic coast of South America. Efforts to expand the inventory of fish species from the northern coast of Brazil led to the identification of two distinct species of Orthopristis from Atlantic South America, based on the analysis of coloration patterns and meristic data, as well as DNA. In the present study, the limits of Orthopristis ruber are reviewed, while Orthopristis scapularis is recognized as a valid species for the northern and northeastern coasts of South America. Based on intermediate morphological characteristics and nuclear DNA markers, a hybrid zone was identified off the state of Espírito Santo, on the eastern Brazilian coast. Additionally, considerations are made on the diversity and biogeography of the coastal marine and estuarine fishes found on the Brazilian coast.
