Biotic homogenization as a threat to native affiliate species: fish introductio...
Douda, Karel; Lopes-Lima, Manuel; Hinzmann, Mariana; Machado, Jorge; Varandas, Simone; Teixeira, Amílcar; Ronaldo, SousaAim: The indirect consequences of biotic homogenization, the process of a gradual increase in the similarity of regional biotas driven by the combined effects of species invasions and extinctions, are still poorly understood. In this study, we aimed to assess the ability of a native affiliate species to maintain its host resources under the condition of biotic homogenization of host communities. Location: Cent...
Ecology of southern European pearl mussels (Margaritifera margaritifera): first...
Varandas, Simone; Lopes-Lima, Manuel; Teixeira, Amílcar; Hinzmann, Mariana; Reis, Joaquim; Cortes, R.; Machado, Jorge; Sousa, Ronaldo1. Southern European populations of Margaritifera margaritifera (L., 1758) are under-studied. From 1986 to 2001 this species was considered extinct in Portugal but between 2001 and 2002 six northern populations were found, five of which were previously unknown. 2. This study comprises a comparative study of the ecology and habitat requirements of two new populations in the rivers Beça and Terva (tributaries of ...
Reproductive cycle and strategy of Anodonta anatina (L., 1758): Notes on hermap...
Hinzmann, Mariana; Lopes-Lima, Manuel; Teixeira, Amílcar; Varandas, Simone; Sousa, Ronaldo; Lopes, Anabela; Froufe, Elsa; Machado, JorgeFreshwater mussels have decreased dramatically in Iberia over the last decades. These animals are responsible for important ecosystem services such as recycling nutrients and improving water clarity. Under this view a better knowledge on the biological features of these animals is extremely important for future conservation and management actions. In this study the reproductive and gametogenic cycle of Anodonta...
Modulation of poly-N-acetylglucosamine accumulation within mature Staphylococcu...
Cerca, Filipe; França, Ângela; Guimarães, Rodrigo; Hinzmann, Mariana; Cerca, Nuno; Cunha, Alexandre Lobo da; Azeredo, Joana; Vilanova, ManuelPNAG is a major component of Staphylococcus epidermidis biofilms involved in intercellular adhesion as well as in the interaction of the biofilm with components of the host immune response. Synthesis of PNAG has been found to be regulated by several environmental factors. In the present study, the effect of glucose metabolism-dependent culture medium acidification in PNAG accumulation was evaluated. Established...
Estudo de dinoflagelados bênticos da Ria de Aveiro (NW Portugal)
Hinzmann, Mariana FonsecaA Ria de Aveiro apresenta ao longo das margens pequenos charcos com características muito peculiares, que oferecem condições para a proliferaçãode um grande número de algas, especialmente algas bênticas pertencentes avários grupos, com a dominância de diatomáceas, dinoflagelados emacroalgas verdes. Verificou-se que a comunidade de dinoflagelados é dominada essencialmentepor espécies pertencentes ao género Proro...
