Islands possess physical characteristics that make them uniquely well-suited for initial field trials of new genetic-based technologies applied to African malaria vectors. This has led efforts characterize the degree isolation island mosquito populations. São Tomé and Príncipe (STP) is a country composed two small islands in Gulf Guinea (Central Africa) where Anopheles coluzzii primary vector. ...

Aim Oceanic islands have played an important role in our understanding of the diversification organisms, and phylogenetic estimates been used this context to investigate origin island diversity its relationship continent. Using a typical orchid genus rich endemics with widespread continental relatives, we aim compare alternative hypotheses focus on endemism. Location Tropical Africa Gulf Guinea...

Colonizations of islands are often associated with rapid morphological divergence. We present two previously unrecognized cases of dramatic morphological change and niche shifts in connection with colonization of tropical forest-covered islands. These evolutionary changes have concealed the fact that the passerine birds madanga, Madanga ruficollis, from Buru, Indonesia, and São Tomé shorttail, ...

Erythema elevatum diutinum is a rare neutrophilic dermatoses with vasculitis, which presents as persistent, symmetrical, purple or brownish papules and nodules, mainly in the extensor surface of the limbs.
