- Bioclimatology, biogeography and land use of Trás-os-MontesPublication . Monteiro-Henriques, T.; Aguiar, CarlosFrequently climate is considered the first factor influencing flora, and consequently, vegetation distribution (Walter 1986; Woodward & B. G. Williams 1987; Capelo 2003; Peinado et al. 2007). Bioclimatology is the science that investigates the relationship between climate and the distribution of organisms. Rivas-Martínez’s Worldwide Bioclimatic Classification (RMWBC) has been developed by Rivas-Martínez with a number of approaches since 1982 (Rivas-Martínez 1996; 2008), with close reference to vegetation distribution, and is currently the most widely applied classification by Iberian phytosociologists, as well as from other Mediterranean countries. Based on the RMWBC, Monteiro-Henriques (2010) produced a set of bioclimatological maps for mainland Portugal (1960-1990) using the climatic statistical interpolations of Silva (2005) and Nicolau (2002) as base data. Using these bioclimatological maps of Monteiro-Henriques (2010) we present thermotype and ombrotype maps for mainland Portugal following the latest version of the RMWBC (Rivas-Martínez 2008), with particular focus on the Morais-Bragança area (Figure 5 and 6).
- Conservation Management of EU Priority Habitats after Collapse of Traditional Pastoralism: Navigating Socioecological Transitions in Mountain RangelandPublication . Honrado, João P.; Lomba, Angela; Alves, Paulo Jorge Mendes; Aguiar, Carlos; Monteiro-Henriques, T.; Cerqueira, Yvonne; Monteiro, Paulo; Caldas, Francisco BarretoAgricultural abandonment is a major driver of change in rural landscapes. Assumed to provide beneficial results to the environment and the conservation of biota, rural abandonment triggers landscape and biotic homogenization and loss of valuable species and habitats. This article focuses on the ecological effects and conservation challenges of shifts in extensive grazing regimes on marginal pastureland of Mediterranean mountains. We conceptualize a navigated socioecological transition toward conservation-oriented management after the collapse of historical land systems. The article provides examples from the LIFE+ project “Higro,” developed in mountainous protected areas in Portugal, of how management for conservation could sustain disturbance-dependent habitats. We argue that actively and regularly managing large habitat areas should be envisaged as a short-term approach to limit the immediate effects of rural abandonment. A gradual integration of conservation targets with other activities in changing rural economies is necessary to foster long-term conservation of species and habitats, building on the link between conservation-oriented habitat management and ecosystem services in rural landscapes. Conservation goals should run alongside recovery of social systems and innovation applied to traditional sources of income. This parallel development would contribute to building up social-ecological resilience by maintaining a diversity of social and ecological capital in rural areas.

- Environmental and landscape rehabilitation: case study for fresh stone treatment on big damsPublication . Icil, Soukayna; Monteiro-Henriques, T.; Soudi, Brahim; Cortez, José PauloThe construction of big dams usually cause a severe environmental change at a local level, producing a considerable visual impact that must be remedied and the disturbed area must be rehabilitated and recovered, approaching the landscape prior to the dam construction. In this work, several assays were tested, with the purpose of finding a treatment for fresh cut granite that could be used as a general rock treatment for visual impact of fresh excavated rocks. Some organic mixtures were tried, using autochthonous lichens and moss, as well as chemical treatments, like acid or paint. Granite blocks were selected and five different treatments were applied to cover the fresh granitic blocks and trigger their colonization and aging. The experiment has been established on two groups of blocks, one submitted to irrigation three times a week and the other without irrigation. Each treatment had two repetitions per group. Two blocks for control were also established in each group to interpret the gaps of variation in comparison to the treated blocks. All the stone blocks were maintained in a greenhouse, with controlled temperature and humidity. The monitoring of the treatment was done by taking pictures every 20 days, that were analyzed using RGB color characteristics and parameters that shows the evolution of pigmentation of the blocks. The results of this study show that three or at least two out of the five tested treatments are recommended to use in the disturbed areas. Irrigation can be more useful for the first two to three weeks after treatments
- FloraPublication . Aguiar, Carlos; Monteiro-Henriques, T.; Coutinho, Xavier Pereira; Sánchez-Mata, D.The invaluable commented checklist of the vascular flora of the ultramafic rocks of northeastern Portugal of Pinto da Silva (1970) has been recently reviewed by Aguiar and Monteiro-Henriques (ined.). These authors’ accept 568 taxa, 29% of which (164 taxa) are new additions to the original catalogue of Pinto da Silva (1970). A subset of it with the most frequent and floristically relevant species is presented in Table 6. New additions have been highlighted with an asterisk (*). The most noticeable neophytes have been included and marked with an open rhombus (◊). A few synonyms have been added to facilitate the reading of the list of Pinto da Silva (1970). Familiar circumscription and higher taxa are according, respectively, to APG III (2009) and Chase & Reveal (2009). The main sources of infrafamiliar taxonomic information were the Flora Iberica (Castroviejo 1981+), Nova Flora de Portugal (Franco 1971; 1984; Franco & Rocha Afonso (1994; 1998), The Checklist of the Portuguese Vascular Flora (Sequeira et al. 2011) and, among others, the taxonomic revisions of Romero et al. (1988) (Agrostis), Díaz Lifante & Valdés (1996) (Asphodelus), La Guardia & Blanca (1987) (Scorzonera), Schippmann (1991) and Voght (1991) (Leucanthemum). We followed different taxonomic or nomenclatural criteria from Flora Iberica or Nova Flora de Portugal in Armeria langei subsp. marizii, Anthyllis sampaioana, A. vulneraria subsp. lusitanica, Alyssum serpyllifolium subsp. lusitanicum, Asplenium adiantum-nigrum subsp. corunnense, Carlina hispanica, Centaurea langei, Festuca elegans subsp. merinoi, Helianthemum apenninum subsp. rothmaleri, Tuberaria guttata and Trifolium striatum var. brevidens. The preparation of a checklist of ultramafic vascular flora is a difficult task. First of all, flora checklists are unfinished assignments because plants come and go with time. On the other hand, the northeastern Portugal ophiolites lithology is heterogeneous and complex. Peridotites, and similar ultramafic rocks, appear in stretched outcrops dispersed among macromorphologically similar basic rocks. The soils that have covered the ultramafic rocks many times catch materials from nearby mafic and leucocratic rocks. Finally, deep soils, rich in organic matter, derived from ultramafic rocks, usually have a similar flora to other nearby lithologies. The serpentine effect is in practice impossible to spatialize and quantify; consequently an ultramafic vascular flora checklist brings together plants of rather diverse ecology, and is by itself of limited scientific value.
- Guia de campo: árvores e arbustos de Portugal ContinentalPublication . Bingre, Pedro; Aguiar, Carlos; Espírito Santo, Dalila; Arsénio, Pedro; Monteiro-Henriques, T.O presente Guia de Campo constitui uma iniciativa editorial absolutamente inédita, a vários níveis, no nosso país. Inédita, por pela primeira vez se reunir num Guia de Campo, uma grande parte das espécies lenhosas que ocorrem em Portugal continental, num total de mais de 400 espécies descritas, quase todas elas com ilustrações. Inédita, por incluir uma série de mapas com a distribuição em Portugal continental das nossas espécies lenhosas nativas. Inédita ainda, pelo facto de ter reunido uma equipa de mais de vinte especialistas portugueses que voluntariamente se disponibilizaram para trabalhar expressamente para a produção deste volume. Este último aspecto é de importância fundamental, já que a produção da presente obra nunca teria sido possível sem a abnegação e a vontade de servir das várias dezenas de pessoas que colaboraram, quer ao nível dos textos, quer ao nível das imagens. Para além das pessoas, há também que mencionar as instituições que foram envolvidas na elaboração do presente Guia, nomeadamente seis herbários de Universidades e Centros de Investigação do Porto, Bragança, Vila Real e Lisboa.
- A methodological approach to potential vegetation modeling using GIS techniques and phytosociological expert-knowledge: application to mainland PortugalPublication . Capelo, Jorge; Mesquita, Sandra; Costa, José C.; Ribeiro, Sílvia; Arsénio, Pedro; Neto, Carlos; Monteiro-Henriques, T.; Aguiar, Carlos; Honrado, João José; Espírito Santo, Dalila; Lousã, MárioAn attempt to obtain a consistent spatial model of natural potential vegetation (NPV) for the mainland Portuguese territory is reported. Spatial modeling procedures performed in a Geographic Information System (GIS) environment, aimed to operationalize phytosociological expert-knowledge about the putative distribution of potential zona1 forest communities dominant in the Portuguese continental territories. The paradigm for NPV assumed was that of RIVAS-MARTINEZ (1976) and RIVAS-MARTINEZ et al. (1999), which presupposes, for a given territory, a univocal correspondence between a uniform combination of bioclimatic stage and lithology given a biogeographical context, and a unique successional sequence leading to a single climax community (i. e. a vegetation series (VS)).
- New contributions on flora and vegetation of northeastern Portugal ultramafic outcropsPublication . Aguiar, Carlos; Monteiro-Henriques, T.; Sánchez-Mata, D.In this work we present some syntaxonomic novelties on the vegetation of the referred ultramafic outcrops focused on three new associations: Jonopsidio abulensis-Sedetum maireani, Armerio daveaui-Agrostietum castellanae and Seseli peixotoani- Avenuletum lusitanicae; in addition, a new nomenclatural combination of an endemic taxon from the Morais massif (Armeria langei subsp. marizii) is proposed. We also clarify the phytocoenotic structure of the Portuguese vegetation series through a simple diagrammatic representation, which is then applied to one unique climatophilous vegetation series present in the ultramafic rocks of northeastern Portugal: Genisto hystricis-Querco rotundifoliae Sigmetum
- O novo catálogo da vegetação portuguesa (Continente, Açores e Madeira): descrição e importância para a conservação da flora e dos habitatsPublication . Costa, José C.; Neto, Carlos; Aguiar, Carlos; Capelo, Jorge; Espírito Santo, Dalila; Honrado, João José; Pinto-Gomes, Carlos; Monteiro-Henriques, T.; Sequeira, Miguel; Lousã, MárioIn this work we propose a syntaxonomic scheme, according to the Code of Phytosociological Nomenclature for the vegetation of Portugal: continental and the Azores and Madeira archipelagos. The scheme encompasses 827 associations (4 communities), 245 alliances, 116 orders, and 64 vegetation classes. The 58 suballiances, 2 suborders and 4 subclasses, are also mentioned, as auxiliary ranks. For the higher syntaxa down to suballiance level, succinct ecological, physiognomic and chorological diagnosis has been made, and the characteristic species are related. New syntaxa names and corrections are described and listed in Annex I. It is also presented a floristic catalogue sheet with the syntaxonomic optimal for each taxon (Annex III). This list contains 2930 taxa.
