Abstract Background Syngnathid fishes (Actinopterygii, Syngnathidae) are flagship species strongly associated with seaweed and seagrass habitats. Seahorses pipefishes highly vulnerable to anthropogenic environmental disturbances, but most currently Data Deficient according the IUCN (2019), requiring more biological ecological research. This study provides first insights into syngnathid populati...

Comparing five species of pipefish, egg size was significantly larger in species with brood pouches (Syngnathus typhle, Syngnathus acus and Syngnathus rostellatus) than in species without brood pouches (Entelurus aequoreus and Nerophis ophidion). Egg size correlated positively with female body size in species with brood pouches, but was similar across female sizes in the species lacking pouches...

In this research, gut lengths and numerical occurrence of gut contents (NO%) of Syngnathus acus, Syngnathus typhle and Nerophis ophidion were examined. The specimens were captured with beach seine net in different habitats (vegetated and sandy-vegetated etc.) at the coasts of Aegean Sea between 2006-and 2008. The zooplanktonic preys were mostly consumed by Syngnathus acus and Nerophis ophidion,...

In complement to the JDS4 traditional fish survey (TFS, mainly by electrofishing), a eDNA metabarcoding-based has been implemented within framework of monitoring program organized DNAqua-Net and in collaboration with INTERREG "MEASURES" program. Water samples were collected at 29 sites from source mouth Danube River, 18 tributaries. Two water (mean volume L per sample) each site filtered situ. ...

Estuarine shallow areas and coastal lagoons are known to receive and concentrate multiple inputs, either from land, rivers or coastal areas, being intensively impacted by chemical contamination, namely endocrine disrupting chemicals (EDCs). Despite the ubiquitous coexistence of several classes of EDCs in most of these aquatic ecosystems, there is still limited information regarding their combin...
