All species are valuable genetic resources for the sugar beet breeding. Only in the very eastern part of the Madeira Island on the islet Ilhéu do Desembarcadouro and Ilhéu Chão the endemic species Beta patula can be found. On both islets the plant number of this very rare species, and of the two widely distributed species B. vulgaris subsp. maritima and P. procumbens was established and the habitat described. The results of the species census are presented. The establishment of a genetic reserve for Beta patula is suggested in this paper with the objective to protect this species more effectively.

Hence, propagation trials of nine endemic plant species of Madeira (Anthyllis lemanniana Lowe, Armeria maderensis Lowe, Cedronella canariensis (L.) Webb & Berthel., Erica maderensis (Benth.) Bornm., Genista tenera (Jacq. ex Murray) Kuntze, Helichrysum melaleucum Rchb. ex Holl, Pericallis aurita (L'Her.) B. Nord., Sideritis candicans Aiton and Teline maderensis Webb & Berthel.) were carried out. Plant propagation requirements and their sexual and vegetative propagation methods were studied. Seed germination success varied between species. Germination rate exceeded 70% in six out of nine species, being lower than 30% in Pericallis aurita, while H. melaleucum seeds did not germinate. Vegetative propagation yielded lower success rates, with three species (Erica maderensis, Genista tenera and Teline maderensis) unable to establish roots, and three species (Helichrysum melaleucum, Pericallis aurita and Sideritis candicans) exceeding 60% of the rooting success. Establishment of the propagation requirements of these species could be regarded an important tool for supporting Madeira's flora conservation programs.

The importance of the establishment of a genetic reserve for this endangered species is also discussed.

Com esta técnica, estabelece -se uma relação entre a variável dependente (presença/ausência de uma espécie) e um conjunto de variáveis potencialmente preditoras, e é criado um mapa com a probabilidade de presença da espécie para uma determinada área de interesse. Neste capítulo, é usado o programa Maxent para criar modelos de distribuição potencial de um conjunto seleccionado de espécies, e os resultados obtidos são discutidos com base no conhecimento de especialistas nessas espécies.ABSTRACT: Predictive models of species distribution emerge as a valuable tool for tackling the lack of distributional information on most taxa. A function between the dependente variable (presence/absence of the species) and a set of potential predictors is established, and a map is generated for the focus area, indicating the probabili...

Desde 2004 que a inventariação detalhada da diversidade destas ilhas tem sido um dos principais objectivos dos projectos ATLÂNTICO e BIONATURA (incluídos no projecto EU INTERREG IIIB). Este livro é a mais recente contribuição destes projectos, apresentando uma lista de todos os fungos, flora e fauna terrestre conhecida, incluindo a dulçaquícola, para dois arquipélagos atlânticos (Madeira e Selvagens). A lista abrange o arquipélago da Madeira, constituído por duas ilhas de maiores dimensões (Madeira e Porto Santo) e três pequenas, cujo conjunto constitui as Desertas (Ilhéu Chão, Deserta Grande e Bugio), e ainda o arquipélago das Selvagens, formado por duas pequenas ilhas (Selvagem Grande e Selvagem Pequena) e um ilhéu (Ilhéu de Fora).ABSTRACT: The Azores, Madeira, Selvagens, Canary Islands and Cape Verde are among the r...

Des analyses genetiques et morphologiques ont ete realisees sur un grand echantillonnage d'especes europeennes et macaronesiennes (328 colonies collectees dans 150 localites environ) afin de i) definir les entites genetiques et ii) trouver les meilleurs caracteres permettant leur identification. Neuf especes sont ainsi reconnues, dont P. platyphylloidea avec des colonies du Canada incluses pour comparaison. La plupart des colonies de Porella sont multiclonales; elles presentent du polymorphisme intra- et inter-specifique et des melanges de thalles mâles et femelles. Au niveau intraspecifique, le niveau de variabilite genetique observe est eleve, specialement chez P. canariensis, P. obtusata et P. platyphylla. Enfin, une cle revisee des especes est donnee.

The analysis of the 18 SNPs revealed that the Macaronesian and Moroccan plants are identical or nearly so to J. p. var. turbinata and quite differentiated from J. phoenicea var. phoenicea. In contrast, the leaf terpenoids showed that the oils of the Macaronesian plants are more similar to the Moroccan plants and not as similar to J. phoenicea or J. p. var. turbinata. At present, it seems prudent to treat the Madeira and Canary Island plants as J. p. var. turbinata.

Since then, and until the summer of 2019, 131 new taxa were cited, namely 30 bryophytes, one pteridophyte and 100 spermatophytes. Based on the compilation of written and unpublished information about the diversity of terrestrial plants cited for Porto Santo, the present work lists 696 taxa, including 134 bryophytes, 13 pteridophytes and 549 spermatophytes. Two species of mosses, Sematophyllum substrumulosum (Hampe) E. Britton and Tortula lanceolata R. H. Zander are pteridophytes, Ophioglossum lusitanicum L. and Hymenophyllum wilsonii Hook are proposed to be considered extinct.

It also contains species specific information (bryophytes: red list status, endemic status, taxonomic group, life strategy; macrolichens: photobiont type, growth form) as well as plot information (Plot_ID, sampling date, coordinates, elevation a.s.l. (m), disturbance type, sampled host tree species).The dataset was used for the paper Boch S, Martins A, Ruas S, Fontinha S, Carvalho P, Reis F, Bergamini A, Sim-Sim M (2019) Bryophyte and macrolichen diversity show contrasting elevation relationships and are negatively affected by disturbances in laurel forests of Madeira island.

Here, we tested whether the phylogeographical pattern of Exormotheca pustulosa Mitt. was the result of vicariance induced by past climatic changes or the outcome of a series of recent long-distance dispersal events. Two chloroplast markers (rps4-trnF region and psbA-trnH spacer) and one nuclear marker (ITS2) were analysed. Phylogenetic and phylogeographical relationships were inferred as well as divergence time estimates and ancestral areas. Exormotheca possibly originated in Eastern Africa during the Late Oligocene/Early Miocene while Exormotheca putulosa diversified during the Late Miocene. Three main E. pustulosa groups were found: the northern Macaronesia/Western Mediterranean, the South Africa/Saint Helena and the Cape Verde groups. The major splits among these groups occurred during the Late Miocene/Pliocene; ...
