- Construções comparativas em português: porque algumas são mais iguais que outrasPublication . Pereira, Sandra; Pinto, Clara; Pratas, FernandaIn Portuguese comparative constructions of inequality, either do que or que may be the syntactic heads of the Degree Clause. There are, however, differences in their distribution: do que is allowed in all contexts, whereas que is barred whenever the Degree Clause includes a finite verb phonologically realized. In the present paper we claim that all canonical comparative constructions in European Portuguese include two full clauses and that, whenever some constituents of the Degree Clause are phonologically null, what we have is a case of ellipsis, whose extent is different for do que and que.

- Evapotranspiration from a Mediterranean evergreen oak savannah: The role of trees and pasturePublication . Paço, Teresa Afonso do; David, Teresa S.; Henriques, Manuel O.; Pereira, João S.; Valente, Fernanda; Banza, João; Pereira, Fernando L.; Pinto, Clara; David, Jorge S.Mediterranean evergreen oak woodlands of southern Portugal (montados) are savannah-type ecosystems with a widely sparse tree cover, over extensive grassland. Therefore, ecosystem water fluxes derive from two quite differentiated sources: the trees and the pasture. Partitioning of fluxes according to these different sources is necessary to quantify overall ecosystem water losses as well as to improve knowledge on its functional behaviour. In southern Iberia, these woodlands are subjected to recurrent droughts. Therefore, reaction/resilience to water stress becomes an essential feature of vegetation on these ecosystems. Long-term tree transpiration was recorded for 6 years from a sample of holm oak (Quercus ilex ssp. rotundifolia) trees, using the Granier sap flow method. Ecosystem transpiration was measured by the eddy covariance technique for an 11-month period (February to December 2005), partly coincident with a drought year. Pasture transpiration was estimated as the difference between ecosystem (eddy covariance) and tree (sap flow) transpiration. Pasture transpiration stopped during the summer, when the surface soil dried up. In the other seasons, pasture transpiration showed a strong dependence on rainfall occurrence and on top soil water. Conversely, trees were able to maintain transpiration throughout the summer due to the deep root access to groundwater. Q. ilex trees showed a high resilience to both seasonal and annual drought. Tree transpiration represented more than half of ecosystem transpiration, in spite of the low tree density (30 trees ha 1) and crown cover fraction (21%). Tree evapotranspiration was dominated by transpiration (76%), and interception loss represented only 24% of overall tree evaporation

- Negação metalinguística e estruturas com nada no português europeuPublication . Pinto, Clara; Martins, Ana Maria,1958-O presente trabalho tem como tema a negação metalinguística em Português Europeu, centrando-se num marcador de negação metalinguística ainda não estudado – o marcador nada. A negação metalinguística foi posta em evidência por Laurence Horn (1989), tendo sido apresentada como um tipo de negação dependente de um contexto discursivo específico. No Português Europeu, a negação metalinguística pode ser veiculada por marcadores de negação não-ambíguos. O principal objectivo deste trabalho é demonstrar que, além dos marcadores metalinguísticos cá/lá e agora, identificados por Martins (2010a), o PE dispõe de outros marcadores da mesma natureza, como é o caso de nada, sobre o qual centraremos a nossa análise. Demonstraremos, através da aplicação dos testes propostos em Horn (1989) e de outros considerados relevantes, que nada é um verdadeiro marcador de negação metalinguística, distinto do marcador enfático nada, e que pertence ao grupo dos marcadores periféricos. Veremos ainda que as estruturas com nada exigem legitimação discursiva prévia e obedecem a uma estrutura-eco, reproduzindo apenas conteúdo previamente introduzido no discurso. A análise do tipo de estruturas em que nada ocorre, privilegiando a elipse de VP, conduzir-nos-á à proposta de que nada seja considerado um marcador de asserção responsiva, que codifica (no domínio de CP) um tipo específico de frase, a objecção (cf. Farkas e Bruce, 2010). Mostraremos também que nada apresenta um requisito de segunda posição, que o impede de ocupar a primeira posição na frase. Veremos que o requisito de segunda posição pode ser satisfeito através de duas estratégias distintas: com topicalização de IP ou através de reanálise morfológica (com o verbo ou com cá/lá). Para a representação sintáctica de nada, adoptaremos uma arquitectura simples de CP. Seguindo a proposta de Drozd (2001), propomos que nada seja gerado em C. Nos casos em que haja lugar à topicalização de IP, todo o IP surgirá como adjunto a CP, de acordo com a proposta de Duarte (1987). Quando se observa reanálise morfológica, o verbo e nada (ou cá/lá e nada) fundir-se-ão em C.
- Post Scriptum: Archivo Digital de Escritura CotidianaPublication . Vaamonde, Gael; Costa, Ana Luísa; Marquilhas, Rita; Pinto, Clara; Pratas, FernandaPost Scriptum: A Digital Archive of Ordinary Writings (P.S.) is a project that aims to collect and publish Portuguese and Spanish private letters written along the Modern Ages. These documents are unpublished epistolary writings, written by authors from different social backgrounds. They could be either masters or servants, adults or children, men or women, thieves, soldiers, artisans, priests, political activists, among other kinds of social agents. Their epistolarity survived by chance, when their paths met the persecution means used by the Inquisition and the civil courts, two institutions that used private correspondence as criminal evidence. These textual resources often present an (almost) oral rhetoric, treating everyday issues of past centuries in a register that hasn’t been easy to study, apart from brief examples. In the proposed paper, discussion over the methodological options that lead to the digital edition available online will be raised. Further, the modernization of texts the POS and syntactic annotation will be explained. The aim is to develop a diachronic and annotated corpus that could be used as an electronical resource for linguistic and historical research of Spanish and Portuguese.
