Global phylogeographic limits of Hawaii's avian malaria
It is shown that Hawaii's avian malaria, which can cause high mortality and is a major limiting factor for many species of native passerines, represents just one of the numerous lineages composing the morphological parasite species. Expand
Host associations and evolutionary relationships of avian blood parasites from West Africa.
Sequence data from two nuclear genes recovered from a limited sample of Plasmodium parasites indicated that inferences regarding host breadth were unlikely to be grossly affected by the use of parasite mitochondrial lineages as a proxy for biological species. Expand
Freshwater paths across the ocean : molecular phylogeny of the frog Ptychadena newtoni gives insights into amphibian colonization of oceanic islands
A synergy of rafting, favourable surface currents and a reduction in salinity of surface waters could allow freshwater paths to open far enough to enable continental flora and fauna to reach these and other isolated oceanic islands. Expand
Rapid parallel evolution of aberrant traits in the diversification of the Gulf of Guinea white‐eyes (Aves, Zosteropidae)
Tempo and patterns of morphological divergence are strongly supportive of an adaptive radiation in the oceanic islands driven by ecological interactions between sympatric white‐eyes. Expand
Coevolutionary patterns and diversification of avian malaria parasites in African sunbirds (Family Nectariniidae)
The coevolutionary history of avian Plasmodium and the widespread African sunbirds, family Nectariniidae is explored using a multi-gene phylogeny and evidence supporting a model of biotic diversification in avan Plas modium of African sunbird is provided. Expand
Advances in Ecological Speciation: an integrative approach
The benefits of integrating ecological and genomic data are highlighted, the role of natural selection in the establishment of reproductive isolation during ecological speciation is discussed and different mechanisms of parallel evolution are discussed. Expand
Tracing the colonization history of the Indian Ocean scops-owls (Strigiformes: Otus) with further insight into the spatio-temporal origin of the Malagasy avifauna
BackgroundThe island of Madagascar and surrounding volcanic and coralline islands are considered to form a biodiversity hotspot with large numbers of unique taxa. The origin of this endemic fauna canExpand
The origin of the world's smallest flightless bird, the Inaccessible Island Rail Atlantisia rogersi (Aves: Rallidae).
It is demonstrated that the Inaccessible Island Rail is nested within the mainly South American 'Laterallus clade' and that it colonized ≥3 million-year-old In inaccessible Island from South America c. Expand
Genetic differentiation between Príncipe Island and mainland populations of the grey parrot (Psittacus erithacus), and implications for conservation
It is found that the two mainland subspecies form two independent lineages, having diverged up to 2.4 million years ago (Ma), and that the Príncipe population is composed of two lineages that diverged in allopatry. Expand
Insularity effects on the assemblage of the blood parasite community of the birds from the Gulf of Guinea.
This study supports the hypothesis that parasite pressure is reduced on islands and finds a very distinct parasite species assemblage on the islands, which was composed of both the most generalist and the most specialist lineages. Expand
