In nature, the Goby fish lives in symbiosis with the burrowing shrimp; serving as a watchman in return for a place to live. Current adaptive learning systems hold an ambiguous position that attempts to compensate for real-world interaction. This paper presents a novel symbiotic-dialog approach to abstract cognitive skill training. The approach is implemented within Goby, a third-party symbiotic...

a vervet monkey (cercopithecus aethiops) housed at quarantine of razi vaccine and serum research institute died following a few days of sickness. multiple abscesses on the surface and inside the liver and enlargement of spleen with pinpoint white spot were the most prominent macroscopic features. we examined the organs of the dead monkey and yersinia enterocolitica was isolated. in histopatholo...

Concentration and electrophoretic properties of blood serum albumin of the round goby Neogobius melanostomus caught in Black Sea and Azov Sea were studied in relation to age, sex, maturation stage and season. Electrophoretic mobility of serum albumin in Black Sea fish increased with age, while in Azov Sea goby it varied less. No differences were observed in albumin characteristics between femal...

Invasive round goby Neogobius melanostomus and bighead goby Ponticola kessleri have successfully colonized freshwater and coastal habitats worldwide. The objective was to use stable isotope analyses to study the foraging and movement of both species at small spatial scales in the Upper Danube River, considering 861 samples from two different years, seasons and sides of the river in an area wher...

The effects of oestrogenic exposure upon exposure indicators and reproductive success in a marine fish were investigated using a series of short and long-term exposures of the sand goby (Pomatoschistus minutus) to oestrogenic materials. A 140 bp cDNA probe for sand goby vitellogenin (VTG) was used to measure hepatic VTG mRNA expression. Effects on other novel and “classical” biomarkers of oestr...

Invasions by alien species may cause a decline in populations of vulnerable protected species through interference and resource competition. During the last decade, four invasive goby species of Ponto-Caspian origin have displayed rapid dispersal in The Netherlands. High densities of these species have been recorded in large rivers and hydrologically connected water bodies such as canals and fl...

Cause-and-effect interpretations of the apparent impacts of biological invasions are confounded by the coincident occurrence of non-native species and changes to abiotic factors. Native community structure and function can vary greatly in space and time, owing to abiotic variables that could potentially be affected by non-native species. Here, we sought to determine the relative importance of a...

The Ponto-Caspian round goby (Neogobius melanostomus) was introduced to the Gulf of Gdańsk, southern Baltic Sea, in the late 1980s, and it has now become the dominant demersal fish species in shallow water. This study aimed to assess diet preferences and the degree of diet overlap between the round goby and the native flounder (Platichthys flesus). Results from time-series of stomach contents a...
