Rubidium, strontium content and strontium isotopic composition of strongly alkalic basaltic rocks from the Cape Verde islands

AbstractScavenging raptors have been postulated to be declining at a rate far higher than predatory raptors. To test this hypothesis we reviewed the historical and present status of the seven raptor species—three scavengers (two kites and a vulture), one partial scavenger (a buzzard) and three species (osprey and two falcons) that take live prey—that breed on the Cape Verde islands. Scavenging raptors have experienced steeper declines and more local extinctions than non-scavengers in Cape Verde, with the partial scavenger midway between the two groups. Causes of scavenger decline include incidental poisoning, direct persecution and declines in the availability of carcasses and other detritus. These findings, which highlight the conservation importance of the island of Santo Antão, indicate the priority that needs to be accorded to scavengers, particularly in Europe where many insular populations are reaching unsustainable levels.

A New Species

The genus Pselactus in the Cape Verde Islands is reviewed. Pselactus obesulus (Wollaston, 1867) from São Vicente is redescribed and P. strakai sp. nov. from São Nicolau is described. Both species are diagnosed and illustrated; their larvae are described, larval morphology is discussed and the current state of knowledge about immature stages of Cossoninae is summarized. The systematic position of the genus within Onycholipini is reviewed, and the placement of genus in Cossoninae is discussed. A short note on biogeography of Pselactus is provided.

This paper takes as a point of departure the hypothesis that Papiamentu descends from Upper Guinea Portuguese Creole (a term covering the sister varieties of the Cape Verde Islands and Guinea-Bissau and Casamance), speakers of which arrived on Curaçao in the second half of the 17th century, subsequently shifted their basic content vocabulary towards Spanish, but maintained the original morphosyntax. This scenario raises the question of whether, in addition to being a creole, Papiamentu can be analyzed as a so-called mixed (or intertwined) language. The present paper positively answers this question by drawing parallels between (the emergence of) Papiamentu and recognized mixed languages.
