Roman agriculture in the conventus Bracaraugustanus (NW Iberia)
João Tereso; Pablo Ramil; Rubim Almeida da SilvaA review of archaeobotanical data, together with new, still unpublished data, from Roman sites in conventus Bracaraugustanus suggests the Romanization of the northwest Iberia brought little changes to the agricultural strategies of local communities in indigenous-type settlements. The main crops remain the same as in the Iron Age: Triticum aestivum/durum, Panicum miliaceum, Hordeum vulgare subsp. vul- gare, Tri...
Status and conservation of Silene section Cordifolia in the Iberian Peninsula: ...
João Rocha; A. Crespí; Rubim Almeida da Silva; F. AmichBackground: Detailed knowledge of a species’ autecology as well as information on the availability of suitable habitats and the impacts of climate change on the species and its habitat are requirements for adequate conservation planning. For this purpose, species distribution modelling has been suggested as an effective tool to assess the potential geographic distributions of species under different clima...
Pollen morphology in tribe Dicomeae Panero and Funk (Asteraceae)
A. Pereira Coutinho; Rubim Almeida da Silva; D. Sa ́ da Bandeira; S. OrtizAbstract To better understand the taxonomy and phy- logeny of the Dicomeae (Asteraceae) the pollen morphol- ogy of seven genera including 15 species of that tribe and six genera with seven species belonging to five related tribes was studied by use of light and scanning electron microscopy. The quantitative data were analysed by use of principal-components analysis (PCA). The exine ultra- structure of Erythroce...
Morpho-environmental characterization of the genus Baldellia Parl. (Alismatacea...
João Rocha; António Crespi; M. Garcia-Barriuso; G. Kozlowski; Rubim Almeida da Silva; Joao Honrado; S. Talavera; F. AmichThe genus Baldellia Parl. has always been a complex taxon. Three species and three subspecies have been proposed for the Iberian Peninsula. The morphological variation of this genus in the Iberian Peninsula, Balearic islands and northern Morocco, and its thermo-pluviometric and altitudinal correlation are the focus of this contribution. Twenty-eight morphological variables were examined and subjected to a multi...
