Ulva lactuca é uma macroalga marinha bioindicadora de poluição, que se prolifera em áreas com concentrações elevadas de rejeito orgânico devido à sua capacidade de fixação de nutrientes, o que evidencia sua função biorremediadora de ambientes aquáticos. Esta capacidade, atrelada às altas taxas de crescimento, a torna ideal para a utilização no tratamento de água em sistemas de aquicultura multitrófica integrada (AMTI), como alternativa ao tratamento químico. Dados da literatura demonstram as propriedades antioxidantes de compostos fenólicos, bem como a presença destes no gênero Ulva. Desta forma, este estudo avaliou a atividade antioxidante total pelo método do DPPH, fenóis totais pelo método de Folin-Denis, e teor de açúcares redutores pelo método de Somogyi-Nelson, de extratos, frações e polissacarídeos extraídos de U. lactuca cultivada em AMTI. Estes experimentos tiveram por objetivo determinar a influência das condições de cultivo nas propriedades antioxidantes relatadas na literatura para algas selvagens da mesma espécie. As frações aquosas apresentaram os maiores teores de compostos fenólicos, porém, menores atividades antioxidantes, o que motivou o isolamento e determinação do teor de açúcares redutores dos polissacarídeos, uma vez que o método utilizado para a determinação de fenóis totais também apresenta resultados positivos em amostras de caráter redutor. As frações hexânicas apresentaram os melhores resultados de atividade antioxidante, com CE50 igual a 0,5 mg/mL.

In the marine environment, single-celled, microscopic, plant-like organisms naturally occur in the well-lit surface layer of any body of water. These organisms, referred to as phytoplankton or microalgae, form the base of the food web upon which nearly all other marine organisms depend. Algal bloom is a rapid increase in or accumulation of the population of about 300 species of algae due to excess nutrients (eutrophication), and is of major global interest as it causes reduction in species diversity, abrupt changes in water quality, and discoloration of the water (green, yellow, brown or red) depending on the species of algae and the type of pigments they contain. Dying blooms can also be an environmental concern as when the cells sink and decay, bacteria break down the organic material, which in turn strips oxygen from the water. This microbial oxygen demand at times leads to very low oxygen levels in the bottom waters, harming aquatic life. Documentation of this sporadic high abundance of algae, together with the significant species richness of the diatoms, requires comprehensive studies in the Sundarban coastal environment, which is facing severe degradation due to natural & anthropogenic stressors. In addition, a better understanding of the effects of algal blooms on seafood quality, the complex biological, chemical and physical interactions and subsequent effects on trophodynamics is needed to develop strategies for effective coastal zone management. The book discusses the occurrence of harmful algal blooms (HABs) caused by the dinoflagellates of the genus Alexandrium and Karenia, or diatoms of the genus Pseudo-nitzschia, which have large and varied impacts on marine ecosystems (such as large-scale marine mortality events that have been associated with various types of shellfish poisonings) depending on the species involved, the environment where they are found, and the mechanism by which they exert negative effects. HABs represent a major environmental problem in all regions of the U.S., and their occurrence is on the rise due to increased nutrient pollution. HABs have severe impacts on human health, aquatic ecosystems, and the economy. Such blooms, known colloquially as red tides due to their red or brown hues, are increasing in frequency and magnitude worldwide as a result of changes in oceanic climate, increased coastal eutrophication and enhanced long-distance dispersal in ballast water. As such, the book offers an in-depth account of the complex biological, chemical and physical interactions of the algal blooms (both innocuous and harmful ones). It also discusses the highly topical issue of the impact of global climate change on the frequency and severity of HABs in the context of alterations in temperature, stratification, light and ocean acidification. Focusing on both basic and applied limnology, this book is a reliable and up-to-date reference resource for students, teachers and researchers engaged in the field of coastal research/management at regional and global scales.

Descripción / Resumen (Español / Castellano): Esta obra colectiva aborda la cuestión económica en al-Andalus como nexo de los diferentes estudios. Este tema, tradicionalmente relegado a un segundo plano, merece destacarse para comprender el devenir histórico de al-Andalus, pues la economía lo impregna todo. Y esto en un sentido amplio, no considerando solamente las actividades productivas y comerciales, sino también las formas que tienen los colectivos de organizarse dentro de un contexto territorial o medioambiental, e incluso la arquitectura que desarrollan para poder vivir. Agricultura, ganadería, minería, emisiones monetarias, cerámica, vidrio, textiles, conforman aspectos clave para poder comprender la vida cotidiana en al-Andalus. Nota biográfica (Español / Castellano): Los autores de esta monografía son un conjunto de especialistas pertenecientes a diferentes instituciones universitarias y de investigación, tanto nacionales como internacionales: María Mercedes Delgado Pérez (Universidad de Sevilla), Luis-Gethsemaní Pérez-Aguilar (IAM-CSIC), James L.

In Vitro Culture of Higher Plants presents an up-to-date and wide- ranging account of the techniques and applications, and has primarily been written in response to practical problems. Special attention has been paid to the educational aspects. Typical methodological aspects are given in the first part: laboratory set-up, composition and preparation of media, sterilization of media and plant material, isolation and (sub)culture, mechanization, the influence of plant and environmental factors on growth and development, the transfer from test-tube to soil, aids to study. The question of why in vitro culture is practised is covered in the second part: embryo culture, germination of orchid seeds, mericloning of orchids, production of disease-free plants, vegetative propagation, somaclonal variation, test-tube fertilization, haploids, genetic manipulation, other applications in phytopathology and plant breeding, secondary metabolites.
