- Aportaciones al conocimiento de la flora y vegetación del centro-occidente ibérico (CW de España y NE de Portugal). Flora and Vegetation of central-western Iberian Peninsula (CW of Spain and NE of Portugal)Publication . Bernardos, Sónia; Amado, Anabela; Aguiar, Carlos; Crespí, António; Castro, Adriano; Amich, FranciscoContinuando 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 biogeográfico Toledano Tagano. Aportamos nuevas citas de diversas especies en la zona estudiada, ampliamos asimismo el área de distribución de varios táxones y, por último, discutimos el encuadre sintaxonómico de algunas especies relevantes.
- Conservation status of the threatened Iberian Peninsula narrow endemic Antirrhinum lopesianum Rothm. (Scrophulariaceae)Publication . Bernardos, Sónia; Amado, Anabela; Aguiar, Carlos; Santos, Cledir; Fernández Diez, Javier; Gonzalez-Talavan, A.; Amich, FranciscoAntirrhinum 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 current conservation status. The total number of individuals thought to exist is only 768, distributed along the valley of the River Duero on the Spanish – Portuguese border (562, 71.2%), and in the Portuguese Sabor River valley (206, 26.8%). The main threat to the species is loss of habitat: about one third of the Iberian populations can be considered threatened; one population containing 37.6% of all these plants (289) is severely threatened. To determine the Area of Occupancy and the Extent of Occurrence, an exhaustive bibliographical survey was carried out, and herbarium specimens deposited in several institutions were revised. It is, therefore, classifiable as Critically Endangered in Portugal and Endangered in Spain
- Contribuición para la caracterización florístico-ambiental del norte de PortugalPublication . Martins, Álvaro; Crespí, António; Castro, Adriano; Fernandes, Claudia P.; Rocha, João; Bernardos, Sónia; Aguiar, Carlos; Amich, FranciscoEn el presente trabajo se hace mención a diferentes taxones específicos e infraespecíficos con distribuciones diversas en el territorio portugués continental. En este sentido, la intensa variabilidad geomorfológica y la intrincada bioclimatología del Norte de Portugal constituyen, ambos, factores ambientales decisivos para comprender el comportamiento florístico de esta parte del país. Los taxones analizados en esta aportación son: Teucrium salviastrum Trigonella polyceratia subsp. amandiana, Ononis viscosa subsp. breviflora var. breviflora, Ononis viscosa subsp. pedroi, Digitalis amandiana, Myosotis welwistchii y Myosotis secunda. De modo a poder contribuir eficientemente en la gestión de la riqueza florística, se procede a la aplicación de una rutina programática multivariada, basada en un sistema de información geográfico (SIG), a partir del cual cada uno de los taxones estudiados es georeferenciado sobre cartografía ambiental (confeccionada y publicada por el Instituto para a Conservação da Natureza, del Ministerio del Ambiente portugués). Los resultados obtenidos confirman el efecto gradual de transición entre el área de influencia bioclimática atlántica y la mediterránea, ambas determinantes para comprender el comportamiento florístico del Norte de Portugal. Several specific and infraspecific taxa with different occurrences in the continental portuguese area are referred in the present work. In the light of these behaviours, the climatic and geomorphological variability of the North of Portugal has been important environmental factors to explain the floristic diversity in this part of the country. In this case, the taxa analysed are Teucrium salviastrum Trigonella polyceratia subsp. amandiana, Ononis viscosa subsp. breviflora var. breviflora, Ononis viscosa subsp. pedroi, Digitalis amandiana, Myosotis welwistchii and Myosotis secunda. Because of the appropriate management of the floristic richness, a multivariate statistic routine is applied on a Geographical Informatic System (GIS) the chorological, geomorphological and climatic characterization for each one are described in this paper. The geological substrate and the altitudinal classes are focused for the geomorphological approach, as well as two biogeographic classifications are used to correlate the occurrence of the taxa and their bioclimatic preferences. In the light of this analytical scheme, every taxa is geo-referenced upon an environmental cartography (elaborated by the Instituto para a Conservação da Natureza). The results obtained are pointing out the floristic progressive differentiation between the atlantic bioclimatic influence and the mediterranean one, both bioclimatic influences decisive to understand the floristic behaviour of the North of Portugal.
- Contribution to the knowledge of Portuguese serpentine flora: ecological characteristics, endemic plants, and implications for biodiversity conservationPublication . Ramírez-Rodríguez, Rubén; Aguiar, Carlos; Amich, FranciscoSerpentine areas are scarce in the world, but contain a large number of endemic taxa. These areas have, in many cases, been little or not at all surveyed from a vegetation and biodiversity conservation point of view. The most important Portuguese serpentine outcrops are found in northeastern Portugal, particularly in the Bragança-Vinhais and Morais massifs. Here, we present a complete ecological-floristic check-list of serpentinophites that are found in these areas since this knowledge is essential for their evaluation, management and conservation. A total of 25 taxa, classified into three categories with different grades of serpentinophily, were included in the list: (1) obligate serpentinophytes (exclusively on serpentine), (2) endemic or widespread taxa that in Portugal occur exclusively in ultramafic outcrops, and (3) preferential serpentinophytes (most of the distribution range, at least 90% of populations, are found on serpentine). Genera common to other Iberian serpentine areas (Andalusian serpentine flora) are Odontarrhena, Arenaria, Armeria, Asplenium, Paragymnopteris, Saxifraga and Silene. The majority of the studied serpentinophytes (72%) occurred in endemic and highly specialized plant communities. About half of the studied serpentinophytes (48%) are assigned in some IUCN threat category. Consequently, it is necessary to implement conservation measures to guarantee the protection of these habitats.
- Plant-based remedies for wolf bites and rituals against wolves in the Iberian Peninsula: therapeutic opportunities and cultural values for the conservation of biocultural diversityPublication . González, José A.; Carvalho, Ana Maria; Vallejo, José Ramón; Amich, FranciscoCombined approaches to local knowledge and folk plant use improve awareness and promote effective strategies for the conservation of significant biocultural patrimony. Moreover, the information reported might be the basis for further appropriate phytochemical and pharmacological research. Therefore we provide an insight into traditional herbal remedies and practices for healing bite injuries in humans and domestic animals caused by the Iberian wolf. Wolf bites are associated with inflammatory processes and rabies is a potential complication AIMS: This paper describes and summarises the medicinal-veterinary empirical and ritual uses of the Iberian flora for wolf injuries and reviews the ethnopharmacological data of specific plants that are already published. The Iberian wolf is a critically endangered subspecies of the grey wolf. Livestock attacks attributed to wolves are increasingly frequent in the Iberian Peninsula, resulting in serious social problems. Interesting strategies for Iberian wolf conservation might be related to traditional grazing practices that are deeply linked with empirical knowledge and local practices passed on by oral tradition, which are also vulnerable now.
- Taxonomic composition and ecological characteristics of the endemic flora of the lower Duero Basin (Iberian Peninsula)Publication . Amich, Francisco; Bernardos, Sónia; Aguiar, Carlos; Fernández-Diez, Javier; Crespí, AntónioThe taxonomical composition and an analysis of four ecological characteristics of the 46 endemic species occurring in the lower Duero Basin (CW Iberian Peninsula) have been made. A comparative analysis of the results reveals that this endemic flora does not comply with the general patterns previously observed in other floras. Predominant life forms are hemicryptophytes (43%) and chamaephytes (22%). As far seed-dispersal is concerned, 54% of the endemic species lack any noteworthy adaptative feature. 89% of the endemic species are pollinated by animals (mostly by insects) and only 1 species is dioecious. Following binary classification of the above characteristics have been used to plot statistically significant associations.

- Traditional ecological knowledge and plant biodiversity conservation in a European transfrontier landscapePublication . González, José A.; Carvalho, Ana Maria; Amich, FranciscoOn the basis of ecological and cultural characterization of the landscape, combined with empirical local knowledge and historic data, this chapter focuses on traditional plant-use in two adjoining natural protected areas at the northern tip of the Spanish-Portuguese border (Iberian Peninsula). The river Douro, one of the major Iberian rivers, known for its impressive canyons, flows across north-central Spain and Portugal to its mouth in the Atlantic Ocean. For a 120-km stretch, the Douro ravines define the frontier between the two countries and create a singular, mosaic-like landscape, shaped by ages long interaction between natural processes and human activities. Despite the physical evidence of a natural border, there is an important shared cultural heritage, with particular significance and similarity in plant-use and local management of habitats and territory. This study shows that to preserve traditional ecological knowledge about plant-use within a transfrontier landscape it is fundamental to overcome difficulties associated with natural resources and territorial management. Moreover, several ideas, tools, skills and effective measures for plant biodiversity conservation are needed, as well as intergovernmental cooperation, which is of crucial importance in an internationally shared landscape.
- Traditional plant-based remedies used to treat wolf bite injuries in Portugal and Spain: phytotherapeutic sources and cultural values for the conservation of an emblematic animal speciesPublication . Gonzalez, José Antonio; Carvalho, Ana Maria; Vallejo, José Ramón; Amich, FranciscoThe Iberian wolf (Canis lupus signatus Cabrera, 1907), an endemic subspecies, is an important element of the rich natural and cultural heritage of the Iberian Peninsula (Portugal and Spain). Despite the decline of this large carnivore species over the last few decades, wolves are still in the imaginary of Iberian rural communities that perceive this canidas both a diabolic creature and a mythic and benign animal. At the present time, livestock attacks attributed to the wolf are more and more frequent in the Iberian Peninsula, resulting in serious social problems. Most problems are due to economic damage caused to domestic animals in isolated rural areas. According to several researchers, some interesting strategies for Iberian wolf conservation might be related to traditional livestock practices
