Enhancing water reuse at a local scale: a constructed wetland case study
Magalhães, J.; Dolbeth, M.; Arenas, F.; Pereira, S.; Tsiamis, G.; Ntougias, S.; Calheiros, C.Constructed Wetlands (CW), as biological treatment systems, mimic the phytoremediation processes found in natural wetlands in an optimized configuration for the improvement of the water quality. They are considered nature-based solutions (NBS) that may support decentralized wastewater treatment providing several ecosystem services, including enhancing water availability and reducing water-related risks. The pre...
Enhancing water reuse at a local scale: a constructed wetland case study
Magalhães, J.; Dolbeth, M.; Arenas, F.; Pereira, S. I. A.; Tsiamis, G.; Ntougias, S.; Calheiros, C.What are Constructed Wetlands? Constructed wetlands (CW) are engineered systems that are inspired by and mimicking processes (physical, biological, and chemical) and functions that occur in natural wetlands. Comprised of several components, impermeabilization liners and substrate, and as the key elements the plants and their associated microorganisms. They were thought primarily for wastewater treatment but now...
Invasive crayfishes as a threat to freshwater bivalves: interspecific differenc...
Meira, A.; Lopes-Lima, M.; Varandas, S.; Teixeira, J.; Arenas, F.; Sousa, Ronaldo GomesFreshwater 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...
Spatial and temporal variation of kelp forests and associated macroalgal assemb...
Pinho, D.; Bertocci, I.; Arenas, F.; Franco, J. N.; Jacinto, D.; Castro, João J.; Vieira, R.; Sousa-Pinto, I.; Wernberg, T.; Tuya, F.Kelp communities are in decline in many regions. Detecting and addressing population declines require knowledge of patterns of spatial and temporal variation in the distribution and abundance of kelps and their associated organisms. We quantified kelp and associated macroalgal assemblages three times over a period of 2 years, at three regions along a natural gradient in temperature and nutrient availability acr...
Patterns of landscape and assemblage structure along a latitudinal gradient in ...
Tuya, F.; Cacabelos, E.; Duarte, P.; Jacinto, D.; Castro, João J.; Silva, T.; Bertocci, I.; Franco, João N.; Arenas, F.; Coca, J.; Wernberg, T.The Portuguese coast has overlapping distributions of species of both boreal and Lusitanian origins; a large number of cold- and warm-water species have their southern or northern distributional range edges here. A latitudinal gradient in ocean climate, particularly sea surface temperature (SST) and primary production, has been described along this coast. Here, we took advantage of this gradient in ocean climat...
A continental scale evaluation of the role of limpet grazing on rocky shores
Coleman, R. A.; Underwood, A. J.; Benedetti-Cecchi, L.; Aberg, P.; Arenas, F.; Arrontes, J.; Castro, J. J.; Hartnoll, R. G.; Jenkins, S. R.; Paula, J.It is critical for our knowledge of biodiversity and ecosystem processes to understand how individual species contribute to ecosystem processes and how these contributions vary in space and time. We used a manipulative field experiment in five locations over 17 º of latitude [from southern Portugal to the Isle of Man (British Isles)] to determine the relative response of rocky intertidal algal assemblages relea...
The role of disturbance in differential regulation of co-occurring brown algae ...
Araújo, R.; Arenas, F.; Åberg, P.; Sousa-Pinto, I.; Serrão, EsterDisturbance is an important structuring factor in intertidal communities. This study aimed at experimentally testing the effects of three important sources of disturbance to intertidal rocky habitats (abrasion, sediment deposition and herbivory) on the survivorship and growth of embryos of canopy forming fucoid species (Fucus vesiculosus and Fucus serratus). Natural levels of sediment deposition and herbivore d...

M.; Arenas, F.; Arrontes, J.; Castro, J.J.; Cruz, T.; Delany, J.; Diaz-Caneja, M.B.; Fernandez, C.; Hawkins, S.J.; McGrath, D.Spatial and temporal variation in the recruitment of the intertidal barnacles Chthamalus montagui Southward and Chthamalus stellatus (Poli) (Crustacea: Cirripedia) over an European scale.
