We describe here the first fossil otoliths from the Middle Miocene (Badenian and Sarmatian) of Belgrade, Serbia. They were obtained from Lower Badenian outcrops at Slanci and from upper Badenian and Sarmatian sediments recovered from four shallow wells near the village of Barajevo. The otoliths from the Lower Badenian of Slanci represent fishes typical for an open marine environment, characteri...

Many species of gobiid fishes adhere to surfaces using a sucker formed from fusion of the pelvic fins. Juveniles of many amphidromous species use this pelvic sucker to scale waterfalls during migrations to upstream habitats after an oceanic larval phase. However, adults may still use suckers to re-scale waterfalls if displaced. If attachment force is proportional to sucker area and if growth of...

Oligotrophic tropical coral reefs are built on efficient internal energy and nutrient cycling, facilitated by tight trophic interactions. In the competition for available prey, some small fishes have evolved to feed apparently barren sand patches that connect hard-substratum in many reef habitats. One strategy obtaining prey from a particulate matrix is sift out items sediment (often called ‘wi...

THE ECOLOGICAL CAUSES AND CONSEQUENCES OF PREY CHOICE AND ONTOGENETIC NICHE SHIFTS IN THE COMMON GOBY Angus Charles Jackson Foraging behaviour of the common goby, Pomatoschistus microp s was investigated in both the United Kingdom and Sweden, with the aim of establishing causes and consequences of prey choice and ontogenetic shifts in diet. Goby life-cycle could be clearly divided into two stag...

Mechanisms that control the longitudinal transport of larvae and juveniles in nursery grounds such as estuaries are reported for some species. However, behaviour population consequences these mechanisms still uncertain. In this study, we tested selective tidal-stream from along-channel (up- downstream) cross-channel (from one margin to other) perspectives two kinds fish: estuarine-resident gobi...
