| The basin of Thau in southern France is a shallow, weakly flushed lagoon which is an important location for oyster cultivation. Phytoplankton analyses were carried out in 1975-1976 and then (almost) continuously since 1987. We report an investigation of 'the balance of organisms' in phytoplankton in relation to reductions in phosphorus loading, using two new tools based on phytoplankton lifeforms: the Plankton Index for Phytoplankton (PIp); Euclidean distance in state space. Our results show the utility of the tools for analysing changes in the ‘balance of organisms’ at the level of functional groups (in our study diatoms and dinoflagellates), but also illustrate the difficulties in demonstrating the reversal of human impacts resulting from eutrophication.... |

| Trabalho selecionado durante a VI Semana de Ciências Agrárias (VI SECIAGRA), realizada de 01 a 03/10/2012 This study aimed to evaluate the effect of levels of metabolizable energy (ME) and digestible lysine (DL) on the final weight, weight gain, feed intake and feed conversion ratio for broilers from 1 to 10 days old. A total of 1,152 male broiler chicks with an average weight of 55 g were distributed in a completely randomized design with a 4 x 4 factorial arrangement, involving four levels of ME (2700, 2825, 2950, and 3075 kcal.kg-1) and four levels of DL (1.08, 1.187, 1.295 and 1.403%), resulting in 16 treatments with three replications and 24 chicks per experimental unit. The levels of digestible lysine and metabolizable energy... |
