Carnivores cross irrigation canals more often through overpasses than through c...
Azedo, Rita; Ilhéu, Ana; Santos, Sara; Vaz, Pedro GAs rainfall becomes scarcer or more erratic, we rely more on irrigation systems for agricultural and human water provision. Impacts of irrigation canals such as the barrier effect on wildlife movements are poorly documented. Although canal culverts and overpasses can be used by wildlife, little is known about their crossing behavior to guide barrier effect mitigation efforts. Over seven years, we recorded mediu...

Detection and possible elimination of the first recorded population of the zebr...
Catita, David; Gama, Mafalda; Azedo, Rita; Banha, Filipe; Pinto, João; Ilhéu, Ana; Anastácio, Pedro ManuelThe zebra mussel, Dreissena polymorpha, has strong economic and environmental effects within a wide range of habitats, including reservoirs, and there is a need to monitor in advance of an arrival so that an elimination might be possible. We report the establishment of the zebra mussel in the Alfundão Reservoir, a small reservoir in south Portugal, 190 km away from the closest known population in Spain. The are...

Salgado, Rui; Potes, Miguel; Albino, André; Apolinário, João; Barbosa, Susana; Bárias, Samuel; Beliche, Paulo; Bortoli, Daniel; Canhoto, PauloThe ALqueva hydro-meteorological EXperiment, ALEX 2014, was an integrated field campaign with measurements of chemical, physical and biological parameters in water and air at different experimental sites in the region of the Alqueva reservoir, a 250 km2 man made lake, in the southeast of Portugal. The Field campaign took place from June 1 to September 30, 2014 and comprises an Intensive Observation Period (IOP)...
ALEX2014: The Alqueva Hydro-Meteorological Experiment
Salgado, Rui; Potes, Miguel; Albino, André; Apolinário, João; Barbosa, Susana; Bárias, Samuel; Beliche, Paulo; Bortoli, Daniel; Canhoto, PauloDuring the four months of the ALEX 2014, the over water fluxes of momentum, heat and mass (H2O and CO2) were obtained with an integrated Open-Path CO2 /H2O Gas Analyser and 3D Sonic Anemometer, mounted on a floating platform (Fig.1) belonging to the Portuguese Environment Agency. The short and long wave, up and down, radiative fluxes were measured at the same place, as well as the water temperature profile. Eig...
