Ameaças à vegetação dunar

As paisagens dunares são sistemas de elevado dinamismo, devido à proximidade do mar e à extrema mobilidade do substrato arenoso e prevê-se que venham a ser severamente afetadas pelas alterações ambientais globais. As dunas são depósitos de areia criados por processos eólicos e apresentam uma vegetação muito característica. Estes depósitos de areia em conjunto com a vegetação formam uma barreira essencial ao avanço do mar durante as marés altas de águas vivas e tempestades. Em Portugal, a degradação dos ecossistemas costeiros é muito preocupante. O problema das espécies exóticas invasoras agravou-se, aumentando a pressão sobre as plantas nativas. Embora este problema não seja o único motivo da degradação dos ecossistemas costeiros, este trabalho pretende divulgar as plantas dunares da zona costeira de Matosinhos, sensibilizar para a proteção e conservação das dunas e alertar para o facto de diversas plantas invasoras rapidamente colonizarem espaços abertos, pondo em causa e estabilidade dos ecossistemas costeiros. O conhecimento detalhado destes ecossistemas permitirá a aplicação de processos de vigilância e monitorização bem como o restauro ecológico de áreas dunares degradadas.

Como seria a Terra sem a lua?

A vida que existe na Terra resulta de um conjunto de circunstâncias muito particulares e raras nas quais se inclui a presença da Lua. A Lua é o satélite natural da Terra e os dois planetas influenciam-se mutuamente. Apesar de ser um pequeno planeta a Lua é responsável por vários fenómenos terrestres como as marés que afetam a velocidade de rotação da Terra. O seu afastamento, apesar de lento é constante e provocará alterações nas condições do planeta que permitem sustentar a vida e afectará algumas espécies em particular.

De-authoring or Authoring?: A plunge into the question of authorship and language in J.M. Coetzee's Foe

J. M. Coetzee's Foe is not only a post-colonial novel, but it is also a re-writing of a classic, and its main themes are language, authorship, power and identity. Moreover, Foe is narrated by a woman, while written by a male, Nobel prize winning South African author. The aim of my tesina is to focus on the question of authorship and the role of language in Foe. Without any claim to be exhaustive, in the first section I will examine some selected extracts of Coetzee's book, in order to provide an analysis of the novel. These quotations will mainly be its metalinguistic parts and will be analysed in the “theory” sections of my work, relying on literary theory and on previous works on the novel. Among others, I will cover themes such as the relationship between speech and writing, the connection between writing, history, and memory, the role of silence and alternative ways of communicating and the relationship between literary authority and truth. These arguments will be the foundation for my second section, in which I will attempt to shed a light on the importance of the novel from a linguistic point of view, but always keeping an eye on the implication that this has on authorship. While it is true that it is less politically-permeated than Coetzee's previous works, Foe is above all a “journey of discovery” in the world of language and authorship. In fact, it becomes a warning for any person immersed in the ocean of language since, while everyone naturally tends to trust speech and writing as the only medium through which one can get closer to the truth, authority never is a synonym of reliability, and language is a system of communication behind which structures of power, misconceptions, lies, and treacherous tides easily hide.

Annotated bibliography on wave-current interaction /

This annotated bibliography discusses 60 key publications dealing with wave-current interaction. Each entry includes a bibliographic identification, keywords, a discussion of contents, and a statement of coastal engineering significance. An index of the entries by keywords is provided in an appendix. The recent growth of the wave-current interaction field is indicated by the fact that more than 30 percent of the selected publications were published in 1978 and 1979. (Author).

Beach changes at Holden Beach, North Carolina, 1970-74 /

Beach profile lines at 21 near-evenly spaced intervals along Holden Beach, North Carolina, between Lockwoods Folly and Shallotte Inlets, were measured from November 1970 to December 1974. These have been analyzed to determine the spatial and temporal variabilities on long-term, seasonal, and short-term scales. Profile lines near the inlets showed the greatest variability in mean sea level (MSL) position, above MSL volume, foreshore slope, and profile envelope. This variability near Lockwoods Folly Inlet was partly enhanced by artificial nourishment at profile line 2. Temporary, low-cost shore protection devices (e.g., sandbag groins) were constructed near that inlet during part of the study. No other modifications or activities that affected beach processes were known to occur during the study period. The central part of Holden Beach was studied separately because of the high variability of the inlet sections at either end of the island. Foreshore slopes along this reach increased from an average of 1:30 at the east end to 1:17 at the west. A seasonal change in above MSL volume indicates loss of sand during autumn and winter, and gain during spring and summer. Changes in MSL shoreline intercept and above MSL volume were highly variable during the study.
