Taxa endémicos dos arquipélagos da Madeira e Selvagens. Endemismos exclusivos e partilhados da Madeira<br />

(M), Porto Santo (PS), Desertas (D) e das Selvagens (S), por categoria taxonómica superior.<br />

Endemic taxa <strong>of</strong> <strong>the</strong> Madeira <strong>and</strong> Selvagens <strong>archipelagos</strong>. Exclusive <strong>and</strong> shared endemics <strong>of</strong> Madeira (M),<br />

Porto Santo (PS), Desertas (D) <strong>and</strong> Selvagens (S) according to higher taxonomic categories.<br />

-Pinto et al. 2005) e para os Açores (Silva et al. 2005). Tendo<br />

em conta a necessária compatibilização das categorias de<br />

estatuto de naturalidade utilizados pelos diferentes autores,<br />

para as Canárias e Cabo Verde (bem como para a Madeira)<br />

consideraram -se como introduzidos os taxa que com<br />

qualquer nível de probabilidade assim foram considerados<br />

nas Checklists referidas. O mesmo critério se aplicou aos<br />

endemismos macaronésicos e taxa autóctones. Os taxa<br />

considerados por Silva et al. (2005) como duvidosos foram,<br />

na ausência de melhor informação, considerados como autóctones.<br />

Na presente lista foram ainda considerados autóctones,<br />

para efeitos dos gráficos que se apresentam, os<br />

taxa “nativos prováveis”. Os endemismos macaronésicos<br />

foram incluídos nos nativos.<br />

A compatibilização dos critérios taxonómicos das listas<br />

publicadas ultrapassaria o âmbito desta obra. Consideraram-<br />

-se os números de taxa publicados nas respectivas Checklists,<br />

mal -grado a detecção de alguns pequenos problemas<br />

resultantes da utilização de diferentes critérios<br />

taxonómicos e nomenclaturais [e.g. Romulea columnae Sebast.<br />

& Mauri subsp. gr<strong>and</strong>iscapa (Webb) G. Kunkel, aceite<br />

nesta lista como endemismo macaronésico, está presumivelmente<br />

incluída em Romulea columnae Sebast. & Mauri.,<br />

referida como “Nativa Segura” na listagem do arquipélago<br />

das Canárias (Acebes Ginovés et al. 2004)].<br />

Total<br />

sumed that both confirmed introduced <strong>and</strong> possible introduced<br />

taxa were included in <strong>the</strong> category for introduced.<br />

The same criteria were applied to Macaronesian endemics<br />

<strong>and</strong> autochthonous taxa. The taxa considered to have a dubious<br />

colonisation status by Silva et al. (2005) were considered<br />

autochthonous, wherever additional information was<br />

not available. The taxa identified as “possible native” in this<br />

list were included in <strong>the</strong> category for native in <strong>the</strong> graph.<br />

Macaronesian endemics were also considered as native<br />

taxa.<br />

To make <strong>the</strong> taxonomic criteria applied in <strong>the</strong> published<br />

checklists <strong>of</strong> vascular plants compatible is beyond <strong>the</strong> scope<br />

<strong>of</strong> this work. As such, <strong>the</strong> number <strong>of</strong> taxa listed in those<br />

checklists was compared, despite some incongruence resulting<br />

from <strong>the</strong> use <strong>of</strong> different taxonomic <strong>and</strong> nomenclatural<br />

criteria [e.g. Romulea columnae Sebast. & Mauri subsp.<br />

gr<strong>and</strong>iscapa (Webb) G. Kunkel listed as Macaronesian endemic<br />

in this work, is presumably included in Romulea columnae<br />

Sebast. & Mauri. <strong>and</strong> referred as “Nativa Segura” in<br />

<strong>the</strong> checklist <strong>of</strong> <strong>the</strong> Canaries (Acebes Ginovés et al. 2004)].
