Towards a framework for assessment and management of cumulative human impacts on marine food websNARA Subscribed
Effective ecosystem‐based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and e...
The occurrence of a single individual of yellowtail tang Zebrasoma xanthurum (Acanthuridae) from Sardinia island (Italy), probably released from an aquarium, is here reported. This represents the first record of this species in the Mediterranean Sea. The overall information available on Acanthurid fishes and other exotic species in the Mediterranean is discussed in the light of the ongoing ecological changes taking place in ro...
Matching genetics with oceanography: directional gene flow in a Mediterranean fish speciesNARA Subscribed
Genetic connectivity and geographic fragmentation are two opposing mechanisms determining the population structure of species. While the first homogenizes the genetic background across populations the second one allows their differentiation. Therefore, knowledge of processes affecting dispersal of marine organisms is crucial to understand their genetic distribution patterns and for the effective management of their populations...
Presence of the Guinean puffer Sphoeroides marmoratus (Lowe, 1838) in the Mediterranean SeaNARA Subscribed
The collection of a single specimen of the Guinean puffer Sphoeroides marmoratus from the Ionian Sea in September 1977, misidentified at that time as Lagocephalus lagocephalus , shows that this subtropical species of fish has occurred in the Mediterranean Sea from 30 years ago.
