Watersiporidae (Bryozoa) in Iberian waters: an update on alien and native species

Oscar Reverter-Gil, Javier Souto

Marine Biodiversity > 2019 > 49 > 6 > 2735-2752

Species of the genus Watersipora comprise an important invasive fouling group but are difficult to identify up to species level. This problem, in conjunction with the recent re-description of several member species, requires the revision of previous records and newly collected material in order to more precisely determine their actual presence and distribution. Here, we revise the identity and distribution...

Gabriel Navarro, Jorge Vicent, Isabel Caballero, Jesús Gómez-Enri, more

Estuarine, Coastal and Shelf Science > 2018 > 204 > C > 1-13

High Amplitude Internal Waves (HAIWs) are physical processes observed in the Strait of Gibraltar (the narrow channel between the Atlantic Ocean and the Mediterranean Sea). These internal waves are generated over the Camarinal Sill (western side of the strait) during the tidal outflow (toward the Atlantic Ocean) when critical hydraulic conditions are established. HAIWs remain over the sill for up to...

Tracking the Mediterranean outflow in the Gulf of Cadiz

Marc Gasser, Josep L. Pelegrí, Mikhail Emelianov, Miguel Bruno, more

Progress in Oceanography > 2017 > 157 > C > 47-71

The Mediterranean Water leaves the western end of the Strait of Gibraltar as a bottom wedge of salty and warm waters flowing down the continental slope. The salinity of the onset Mediterranean Outflow Water (MOW) is so high that leads to water much denser (initially in excess of 1.5kgm⁻³) than the overlying central waters. During much of its initial descent, the MOW retains large salinity anomalies...

Journal of Vegetation Science > 28 > 2 > 436 - 444

Question Does the number and relative abundance of sandstone specialist woody species in Mediterranean heathland (herriza) communities of the Strait of Gibraltar decrease with increasing sandstone patch isolation? If so, does this reduction suggest deterministic (ecological filtering) or random (ecological drift) effects? Location Strait of Gibraltar region. Methods We recorded the identity and...

Environmental factors determining the establishment of the African Long‐legged Buzzard Buteo rufinus cirtensis in Western Europe

Darío Chamorro, Jesús Olivero, Raimundo Real, Antonio‐Román Muñoz

Ibis > 159 > 2 > 331 - 342

Winters have become warmer under the impact of climate change, which has modified the phenology as well as the distribution ranges of birds. The African Long‐legged Buzzard Buteo rufinus cirtensis has recently colonized Europe via the Strait of Gibraltar. We aim to explain the native distribution of this species and to predict favourable areas in newly colonized parts of Europe using geospatial modelling...

Marine mollusc exploitation as evidenced by the Gorham's Cave (Gibraltar) excavations 1998–2005: The Middle–Upper Palaeolithic transition

Darren Andrew Fa, James Clive Finlayson, Geraldine Finlayson, Francisco Giles-Pacheco, more

Quaternary International > 2016 > 407 > PB > 16-28

There is increasing evidence that humans have exploited intertidal and shallow-water species for much longer than has been previously considered, and certainly not restricted to Anatomically Modern Humans (AMH). One of the principal reasons for the lack of evidence up till recently has been a lack of consideration for the temporal and spatial backdrop to such activities throughout human evolution,...

A discontinuous Galerkin method for two-layer shallow water equations

Nouh Izem, Mohammed Seaid, Mohamed Wakrim

Mathematics and Computers in Simulation > 2016 > 120 > Complete > 12-23

In this paper, we study a discontinuous Galerkin method to approximate solutions of the two-layer shallow water equations on non-flat topography. The layers can be formed in the shallow water model based on the vertical variation of water density which in general depends on the water temperature and salinity. For a water body with equal density the model reduces to the canonical single-layer shallow...

Trends of autumn counts at Iberian migration bottlenecks as a tool for monitoring continental populations of soaring birds in Europe

Beatriz Martín, Alejandro Onrubia, Andrés Cruz, Miguel Ferrer

Biodiversity and Conservation > 2016 > 25 > 2 > 295-309

Migration monitoring may allow us to detect population trends over large geographic areas because the pattern of change in migrant counts may be expected to follow the pattern of change in population size. We analysed recent regional European population trends of migratory soaring birds from rates of change in migration counts over the Strait of Gibraltar (Spain) during the years (1999–2013). An additional...

Fisheries Oceanography > 25 > 1 > 54 - 66

Thirteen adult bluefin tuna were tracked with electronic pop‐up satellite tags during their reproductive migration towards Mediterranean spawning grounds as they entered the Strait of Gibraltar. Fish were caught in tuna traps and tagged either underwater, with the aid of a modified spear gun, or on the deck of the boat. Fish tagged on board initially showed a shallower behavior than those tagged in...

Mediterranean waters along and across the Strait of Gibraltar, characterization and zonal modification

Cristina Naranjo, Simone Sammartino, Jesús García-Lafuente, María J. Bellanco, more

Deep-Sea Research Part I > 2015 > 105 > Complete > 41-52

Hydrological data collected in the Strait of Gibraltar have been used to examine the distribution and spatial–temporal evolution of the water masses in the area. The spatial variability has been addressed by means of a clustering method that determines the affinity of a collection of temperature–salinity samples to one of the water masses involved in the exchange. The method, which has been applied...
