MAMMALS IN PORTUGAL: A data set of terrestrial, volant, and marine mammal occur...

Mammals are threatened worldwide, with 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mam mals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems func tionality and resilience, and theref...

The role of holm oak edges in the control of disturbance and conservation of pl...

Holm oak (Quercus rotundifolia) woodlands have been able to persist in fire-prone landscapes in northern Portugal where they seem to play a relevant role in community and landscape level patterns and processes, namely in the control of disturbance events and in the maintenance of biodiversity. In this research we tested the following hypotheses: (i) holm oak woodlands affect fire behavior, mainly by disrupting ...

Herbaceous plant diversity across fire created edges in continental holm oak wo...

We analyzed herbaceous plants distribution across edges of holm oak (Quercus rotundifolia) woodlands created and maintained by fire in order to describe plant community structure across edges and to evaluate the role of fire in the patterning of plant diversity at the patch scale. We recorded abundance in twelve 60 m long sampling lines placed perpendicularly to the woodlands boundary at 1, 5, 10, and 20m outsi...

Helianthemum apenninum (L.) Mill. subsp. apenninum (Cistaceae), um caméfito nov...

O Helianthemum apeninnum subsp. apenninum é um caméfito sufruticoso acinzentado, de distribuição mediterrânica-europeia. Na Primavera de 2005 detectamos este taxon nos planaltos de Miranda e da Beira Alta, onde, consoante pudemos averiguar entre 2006 e 2009, ocorre com alguma frequência. Curiosamente, não encontramos na bibliografia florística referente a Trás-os-Montes qualquer alusão a este pequeno arbusto, p...

Conservation status of the threatened Iberian Peninsula narrow endemic Antirrhi...

Antirrhinum lopesianum Rothm. is a narrow endemic of the Lusitan Duriensean biogeographical sector (central western Spain and north-eastern Portugal). The species is listed as threatened in several Spanish documents, although it does not figure as such in any Portuguese document. This paper provides a detailed study of its distribution, estimates of the sizes of its populations, the threats it faces, and its cu...

Flora e Vegetação do Douro na envolvente do Maciço de Poiares

Aportaciones al conocimiento de la flora y vegetación del centro-occidente ibér...

Continuando con nuestros estudios sobre la Flora y Vegetación en el centro occidente ibérico, y en particular en la Cuenca del Duero (p.e. Amado et al. in Aguiar et al., 2003; Bernardos et al., 2003; Crespí et al., 2003; Bernardos et al., 2004), presentamos ahora diversos resultados de índole corológica, taxonómica y fitosociológica obtenidos en estos territorios lusitano durienses, así como en el sector biogeo...
