Standardised inventories of spiders (Arachnida, Araneae) of Macaronesia III: dr...
Crespo, Luís Carlos; Cardoso, Pedro; Malumbres-Olarte, Jagoba; Pereira, Fernando; Romeiras, Maria; Ros-Prieto, Alejandra; Rigal, FrançoisBackground With this publication, we contribute to the knowledge of the arachnofauna of Cabo Verde, focusing specifically on the Islands of Santo Antão and São Vicente. Data were obtained from samples collected as part of the project "Macaronesian Islands as a testing ground to assess biodiversity drivers at multiple scales" (FCT - MACDIV, 2015-2018). This project aimed to identify the factors influencing commu...
Habitat filtering and inferred dispersal ability condition across‐scale species...
Malumbres‐Olarte, Jagoba; Rigal, François; Girardello, Marco; Cardoso, Pedro; Crespo, Luís Carlos; Amorim, Isabel R.; Arnedo, Miquel; Boieiro, MárioAim Habitat diversity has been linked to the diversity and structure of island communities, however, little is known about patterns and processes within habitats. Here we aim to determine the contributions of habitat type and inferred dispersal frequency to the differences in taxonomic structure between assemblages in the same island habitat. Location The Macaronesian archipelagos (Azores, Madeira, the Canary I...
Current status and trends in Cabo Verde agriculture
Monteiro, Filipa; Fortes, Arlindo; Ferreira, Vladmir; Essoh, Anyse Pereira; Gomes, Isildo; Correia, A. Manuel; Romeiras, MariaWith climate change, drought is expected to increase, and its negative impacts will be particularly important in developing countries, usually with rainfall-dependent agriculture. The Cabo Verde archipelago is characterized by limited resources, remoteness, vulnerability to natural disasters, and a fragile environment. In this study, we provide the first report of the current status and trends of agriculture in...
Spatial and temporal trends of burnt area in Angola: implications for natural v...
Catarino, Silvia; Romeiras, Maria; Figueira, Rui; Aubard, Valentine; Silva, João M.N.; Cardoso Pereira, José MiguelFire is a key driver of natural ecosystems in Africa. However, human activity and climate change have altered fire frequency and severity, with negative consequences for biodiversity conservation. Angola ranks among the countries with the highest fire activity in sub-Saharan Africa. In this study, we investigated the spatial and temporal trends of the annual burnt area in Angola, from 2001 to 2019, and their as...
Biodiversity of vegetation and flora in Tropical Africa
Catarino, Luís; Romeiras, MariaAfrican 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, depends on plants for their survival and welfare, but many ecosystems are being degraded, mostly due to the growing impacts of clim...
The role of climate and topography in shaping the diversity of plant communitie...
Neto, Carlos; Costa, José Carlos; Figueiredo, Albano; Capelo, Jorge; Gomes, Isildo; Vitória, Sónia; Semedo, José Maria; Lopes, António; Dinis, HerculanoThe flora and vegetation of the archipelago of Cabo Verde is dominated by Macaronesian, Mediterranean, and particularly by African tropical elements, resulting from its southernmost location, when compared to the other islands of the Macaronesia (i.e., Azores, Madeira, Selvagens, and Canary Islands). Very likely, such a geographical position entailed higher susceptibility to extreme climatic fluctuations, namel...
Diversification of African tree legumes in Miombo-Mopane woodlands
Maquia, Ivete; Catarino, Sílvia; Pena, Ana R.; Brito, Denise R.A.; Ribeiro, Natasha S.; Romeiras, Maria; Ribeiro-Barros, Ana I.The southern African Miombo and Mopane ecoregions constitute a unique repository of plant diversity whose diversification and evolutionary history is still understudied. In this work, we assessed the diversity, distribution, and conservation status of Miombo and Mopane tree legumes within the Zambezian phytoregion. Data were retrieved from several plant and gene databases and phylogenetic analyses were performe...
Shortcomings of phylogenetic studies on recent radiated insular groups: a meta-...
Romeiras, Maria; Pena, Ana Rita; Menezes, Tiago; Vasconcelos, Raquel; Monteiro, Filipa; Paulo, Octávio S.; Moura, MónicaOver the previous decades, numerous studies focused on how oceanic islands have contributed to determine the phylogenetic relationships and times of origin and diversification of di erent endemic lineages. The Macaronesian Islands (i.e., Azores, Madeira, Selvagens, Canaries, and Cabo Verde), harbour biotas with exceptionally high levels of endemism. Within the region, the vascular plants and reptiles constitute...
Restructuring of the "Macaronesia" biogeografic unit: a marine multi-taxon biog...
Freitas, Rui; Romeiras, Maria; Silva, Luís; Cordeiro, Ricardo; Madeira, PatríciaThe Azores, Madeira, Selvagens, Canary Islands and Cabo Verde are commonly united under the term “Macaronesia”. This study investigates the coherency and validity of Macaronesia as a biogeographic unit using six marine groups with very different dispersal abilities: coastal fishes, echinoderms, gastropod molluscs, brachyuran decapod crustaceans, polychaete annelids, and macroalgae. We found no support for the c...
