Abstract

African ecosystems comprise a wealthy repository of biodiversity, with a high proportion of native and endemic plant species, which makes them biologically unique and providers of a wide range of ecosystem services. A large part of African populations, in both rural and urban areas, depend on plants for their survival and welfare, but many ecosystems are being degraded, mostly due to the growing impacts of climate change and other anthropogenic actions and environmental problems. Loss of habitat and biodiversity affects livelihoods, water supply and food security and reduces the resilience of ecosystems in the African continent. The knowledge about the great African plant and ecosystem diversity, and the structure, composition and processes involved in vegetation dynamics, is crucial to promote their sustainable use and to preserve one of the most understudied regions in the world. This Special Issue aimed to gather contributions that update and improve such knowledge.

Abstract

Based on the inventory of herbarium materials and in the late collections, is presented a check-list of the Guinea-Bissau's vascular flora and made reference to the non vascular taxa known in the country. In the vascular flora 1606 specific and infraspecific taxonomical groups were registered, of which 1462 autochthonous, belonging to 699 genera, a figure widely higher than the thousand species so far estimated. Four taxa known only from this country are also referred. In the chorology of the autochthonous taxa, occurs 27% of elements of restricted distribution, predominantly of the guineo-congolan region; 19% of linking elements, mainly sudano-guinean and sudano-guineo-congolese; 27% of afrotropical elements and 27% of pluricontinental elements, mostly pantropical and paleotropical.For the study of the plant communities, 232 phytoecological surveys were made, distributed in all the territory and in the different kinds of habitats. The classification of the surveys in groups representing plant communities was made with the NTSYS program, using their floristic compositions and degrees of abundance. The 29 communities considered are characterized floristicaly and physiognomicaly and related with edafo-climatic factors and man-made disturbance. The terrestrial vegetation in the country is largely of secondary character, shaped by ancient, frequent and continued human intervention, being the fire the anthropic factor that more influences its ecology.A draft of a Guinea-Bissau phytogeographic map is presented, considering two main zones. The Guinean Sector, in the western part of the country, includes the Insular, South Guinean and North Guinean Subsectors. The Sudanese Sector, in the eastern part of the country, includes the Boé hils Subsector and the plains and Bafatá and Gabu peneplains Subsector.
