Spatial and temporal variations of Cockle (Cerastoderma spp.) populations in tw...
Santos, Cátia; Cabral, Sara; Carvalho, Frederico; Sousa, António; Goulding, Thomas; Ramajal, João; Medeiros, João Paulo; Silva, GildaCockles are amongst the most exploited bivalve species in Portugal, playing an important ecological and socioeconomic role in coastal ecosystems. Two sympatric species of cockles, Cerastoderma edule (Linnaeus, 1758) and Cerastoderma glaucum (Bruguiere, 1789-1792) may co-occur in estuaries and coastal lagoons in mixed populations along the European Atlantic coast, namely in Portugal, France and the United Kingdo...
Management Models of the Manila Clam (Ruditapes philippinarum) Fisheries in Inv...
Coelho, Pedro; Carvalho, Frederico; Goulding, Thomas; Chainho, Paula; Guerreiro, JoséThe Manila clam (Ruditapes philippinarum, Adam & Reeve 1850) is a non-indigenous species that was introduced in Europe (France) in the 1970s for commercial purposes, and reached Portugal in the 1980s. Currently, it occurs in several European coastal systems, from the Bay of Biscay to the north Mediterranean. In Portugal, it is present in estuarine systems and coastal lagoons from the north to south, such as Ria...
Shifts in estuarine macroinvertebrate communities associated with water quality...
Goulding, Thomas; Sousa, Pedro M.; Silva, Gilda; Medeiros, João Paulo; Carvalho, Frederico; Metelo, Inês; Freitas, Catarina; Lopes, Nuno; Chainho, PaulaThe present work aims to identify changes in the macroinvertebrate community of the Tagus estuary (Portugal) due to improvements in water quality and to climate change. Data was collected over a period of 16 years (1998–2014) from different sites located along the estuarine gradient. The AZTI Marine Biotic Index (AMBI) was used to assess the ecological quality status based on benthic invertebrate communities an...
