Vision is an important source of information for many animals. The crystalline lens plays a central role in the visual pathway and hence the ecology of fishes. In this study, we tested whether the different light regimes in the Mediterranean and Red Seas have an effect on the optical properties of the lenses in the rivulated rabbitfish, Siganus rivulatus. This species has migrated through the S...

In recent years, Shewanella putrefaciens, commonly known as a halophilic bacteria, has been associated with serious health disorders in freshwater fish. Therefore, it has been described as a new aetiological agent of the disease, named shewanellosis. S. putrefaciens is a heterogeneous group of microorganisms, belonging to the Alteromonadaceae family. Based on different criteria, three biovars a...

This study aimed to determine the catch composition and compare per unit effort (CPUE) of indigenous non-indigenous species in longline trammel net fisheries Mediterranean coasts Türkiye. The data were collected weekly from May 2020 September 2021 by commercial fishing vessels ( n = 62 days for nets, 75 longlines). results indicated that more than 90% consisted fishery Pterois miles (Bennett, 1...

Biological invasions are a human-induced environmental disturbance that can cause major changes in ecosystem structure and functioning. Located the northeastern Mediterranean basin, Aegean Sea is hotspot of biological invasions. Although presence alien species has been studied monitored, no assessment conducted on their cumulative impacts native biodiversity. To address this gap, we applied CIM...

Gobiid fishes of the genus Gobiodon live in strong association with certain reef-building corals that vary considerably in size and architecture. These fishes hence are excellent model systems for studying evolutionary adaption to specific microhabitats. Using a sample of Gobiodon histrio and G. rivulatus and their most important host corals (Acropora digitifera and A. gemmifera) from the north...

Information on the initial stages of dispersal and settlement are of great interest in understanding the dynamics of biological invasions and in designing management responses. A newly settled population of the Lessepsian rabbitfish migrant Siganus luridus, that arrived in Linosa Island (Sicily Strait) in 2000, offered a unique opportunity to examine the genetic variability of the early phase o...
