Development and multiplexing of microsatellite loci for the near threatened fre...
Froufe, Elsa; Sobral, Carina; Teixeira, Amílcar; Lopes, Anabela; Sousa, Ronaldo; Varandas, Simone; Lopes-Lima, Manuel1. The Unionidae are among the most endangered fauna in the world and globally in decline. They are particularly vulnerable to habitat loss and fragmentation, susceptible to flow, pollution and climatic disturbances and introduction of invasive species. Despite their well-recognized ecological and conservation importance, there is a surprising lack of genomic resources currently available for European species. ...
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...
Ecological status of a Margaritifera margaritifera (Linnaeus, 1758) population ...
Sousa, Ronaldo; Amorim, Angela; Sobral, Carina; Froufe, Elsa; Varandas, Simone; Teixeira, Amílcar; Lopes-Lima, ManuelAn important population of the critically endangered pearl mussel Margaritifera margaritifera (Linnaeus, 1758) was surveyed at the edge of its southern distribution (River Paiva, Portugal). Although an earlier study suggested that this population had a very low number of individuals (<500), a narrow distribution, and was mainly comprised by old specimens our data contradict these findings. Our assessment estima...
Bioecologia dos mexilhões de água doce (Unionidae) nos rios Sabor, Tua e Tâmega...
Teixeira, Amílcar; Varandas, Simone; Sousa, Ronaldo; Froufe, Elsa; Lopes-Lima, ManuelForam avaliadas as condições ambientais das populações de náiades (Mollusca, Bivalvia, Unionidae) em diferentes troços dos rios Tâmega, Tua e Sabor, na proximidade de grandes empreendimentos hidroelétricos em fase de construção. No verão dos anos 2010, 2011 e 2012 foi caracterizado o habitat e microhabitat disponível e usado pelas espécies Unio delphinus, Anodonta anatina e Potomida littoralis. Recorreu-se à me...
