The present study constitutes the first evaluation of the space colonization strategies performed by Rugulopteryx okamurae when co-occurring with the resident macroalgal community in the introduced areas. Since the first apparition of the nonindigenous macroalga in the Strait of Gibraltar, its high propagation capacity together with its...

A case of intergeneric hybridization in the wild between a female bottlenose dolphin (Tursiops truncatus) and a short-beaked common dolphin (Delphinus delphis), considered members of 'vulnerable' and 'endangered' subpopulations in the Mediterranean, respectively, by the International Union of Conservation of Nature is described in this paper....

La especie Delphinus delphis Linnaeus 1758 está considerada en "peligro crítico de extinción" en Andalucía. En la bahía de Algeciras se localiza de forma permanente, donde se alimenta y reproduce. Durante el periodo de estudio se registraron partos, neonatos y crías en los grupos, observándose que el máximo número estimado de neonatos coincide...

Mechanisms that control the longitudinal transport of larvae and juveniles in nursery grounds such as estuaries are reported for some species. However, the behaviour and population consequences of these mechanisms are still uncertain. In this study, we tested selective tidal-stream transport from the along-channel (up- and downstream) and...

The invasive macroalga Rugulopteryx okamurae represents an unprecedented case of bioinvasion by marine macroalgae facing the European coasts. Since the first apparition of the species in the Strait of Gibraltar in 2015, its fast dispersion along the introduced habitats constitutes a real challenge to develop monitoring strategies that ahead of...

Durante los últimos dos años, el alga exótica Rugulopteryx okamurae se ha expandido de forma muy agresiva sobre fondos rocosos iluminados del submareal en zonas del estrecho de Gibraltar, produciendo graves impactos sobre las comunidades bentónicas preestablecidas, la acumulación de miles de toneladas de algas de arribazón y problemas de...
