Invasive crayfishes as a threat to freshwater bivalves: Interspecific differenc...
Meira, Alexandra; Lopes-Lima, Manuel; Varandas, Simone; Teixeira, Amílcar; Arenas-Arenas, Francisco José; Sousa, RonaldoFreshwater bivalves have suffered major global declines, being the introduction of invasive alien species (IAS) an important, but not well studied, mechanism of threat. This study assessed the predator-prey relationship between two non-native crayfish species (Procambarus clarkii and Pacifastacus leniusculus) and three native (Anodonta anatina, Potomida littoralis and Unio delphinus) and one non-native (Corbicu...
Invasive crayfishhes as a threat to native freshwater bivalves
Sousa, Ronaldo; Meira, Alexandra; Arenas-Arenas, Francisco José; Lopes-Lima, Manuel; Varandas, Simone; Teixeira, AmílcarProcambarus clarkii and Pacifastacus leniusculus are problematic invasive species and may affect freshwater bivalves. In this study we verified ifthese crayfish species can predate native (Anodonta anatína, Potomida littoralis and Unio delphinus) and non-native (Corbicula fluminea) bivalves through experiments in laboratory and validation in the field (Sabor basin, North of Portugal). In the laboratoiy, crayfis...
Conbiomics: the missing approach for the conservation of freshwater bivalves
Froufe, Elsa; Fonseca, Miguel M.; Teixeira, Amílcar; Varandas, Simone; Gonçalves, Duarte V.; Hinzmann, Mariana; Arenas-Arenas, Francisco JoséThe decline of freshwater biodiversity hás reached alarming proportions. The extinction rate of freshwater biodiversity is predicted to be five times faster than ali other groups of species. The Unionidae, being the largest of the freshwater bivalve families, is among the most endangered group in the world. They are important providers of aquatic ecosystem services and are characterized by an unusual pattem of ...

Cardeñosa, Vanessa; Barros, Lillian; Barreira, João C.M.; Arenas-Arenas, Francisco José; Moreno-Rojas, José M.; Ferreira, Isabel C.F.R.“Lane Late” sweet orange grafted on six different citrus rootstocks and grown in the Guadalquivir valley (Seville, Spain) were picked at different ripening stages in two consecutive seasons to characterize their antioxidant activity (free radicals scavenging activity, reducing power and lipid peroxidation inhibition) and quantify their main antioxidant compounds (vitamin E and vitamin C). Linear discriminant an...
Variety and Harvesting Season Effects on Antioxidant Activity and Vitamins Cont...
Cardeñosa, Vanessa; Barreira, João C.M.; Barros, Lillian; Arenas-Arenas, Francisco José; Moreno-Rojas, José M.; Ferreira, Isabel C.F.R.Five sweet orange (Citrus sinensis Osbeck) varieties cultivated in Huelva (Spain) and picked at two seasons during two consecutive years, were characterized for their antioxidant activity (free radicals scavenging activity, reducing power and lipid peroxidation inhibition) and vitamin content (vitamin E and vitamin C). The effects induced by sweet orange variety and stage of maturity were comprehensively compar...
