Historical biogeography of the widespread macroalga Sargassum (Fucales, Phaeophyceae)

Comparison of antifouling properties of native and invasive Sargassum (Fucales, Phaeophyceae) species

The invasiveness of algal species can be facilitated by chemo-ecological traits that allow the establishment of invasive species in a highly competitive environment. Anti-bacterial, anti-quorum sensing, anti-diatom and anti-larval properties of the invasive brown macroalga Sargassum muticum and three native Sargassum species from Oman waters were compared in laboratory and field experiments to ...

Sargassum kendrickii (Fucales, Phaeophyceae), a new species of subgenus Phyllotrichia from southern Australia

Sargassum kendrickii N. Goldberg et Huisman, sp. nov. is described from subtidal habitats in the Esperance region, southern Western Australia. The new species belongs to the subgenus Phyllotrichia and can be distinguished from all previously described species in the morphology of its lateral branches, which are pinnate, alternately arranged, and have serrated margins. Vesicles are absent and re...

Historical Biogeography

Historical biogeography can be divided into two subdisciplines: taxon biogeography and area biogeography. In the former we are interested in reconstructing the geographic distribution history of a particular group of organisms. Questions we may be interested in answering include: Where did the organisms originate? How did they colonize the areas in which they live today? When did they first com...

The historical biogeography of Mammalia.

Palaeobiogeographic reconstructions are underpinned by phylogenies, divergence times and ancestral area reconstructions, which together yield ancestral area chronograms that provide a basis for proposing and testing hypotheses of dispersal and vicariance. Methods for area coding include multi-state coding with a single character, binary coding with multiple characters and string coding. Ancestr...
