schismatogobius deraniyagalai is recorded from the seethanathi river of karnataka state in the southern part of india. previous records of these species were from the streams in kerala of india and from freshwater habitats of sri lanka. herein we report the occurrence of this species in seethanathi river showing its distribution extended further north along the west coast of peninsular india.

This research explored stereotypes associated with labels for White people: whites, white trash, and redneck. It also examined how these labels affect attitudes toward white subgroups. Participants described whites as dominant, elite, middleclass, and privileged. Rednecks and white trash were described with stereotypically negative characteristics, such as poor and uneducated. White trash were ...

Index words: Gobiidae Invasive species Neogobius Proterorhinus Round Goby Tubenose Goby The species identities, scientific names, and relationships of Eurasian gobies that invaded the Laurentian Great Lakes – and other species that are predicted to invade in the future – are evaluated here using recently resolved DNA characters. The Round Goby and the Freshwater Tubenose Goby entered the Great ...

The 24 hour activity patterns of three non-native gobiids (round goby Neogobius melanostomus, Western tubenose goby Proterorhinus semilunaris and bighead goby Ponticola kessleri) were assessed over 46 consecutive months between 2011 and 2014 from their occurrence in the cooling water intake of a nuclear power plant on the River Rhine, Germany. In total, 117717 gobiids were identified and classi...

Females of the stream goby Rhinogobius sp. DA with paternal care favor males courting in fast water currents, whereby they mate males of high parental ability. Here we examined female choice of male nest size of this goby in laboratory. The dichotomous choice experiment clearly indicated that females prefer large nests. Spawning at large nests seems to improve egg survival rates in natural habi...

Male reproductive phenotypic plasticity related to environmental-social conditions is common among teleost fish. In several species, males adopt different mating tactics depending on their size, monopolizing mates when larger, while parasitizing dominant male spawns when smaller. Males performing alternative mating tactics are often characterized by a strong dimorphism in both primary and secon...

Acoustic signals can encode crucial information about species identity and individual quality. We recorded and compared male courtship drum sounds of the sand goby Pomatoschistus minutus and the painted goby P. pictus and examined if they can function in species recognition within sympatric populations. We also examined which acoustic features are related to male quality and the factors that af...

Yellowfin goby Acanthogobius flavimanus affected with X-cell pseudotumors were sampled from a river estuary in Tokyo Bay, Japan. We amplified the gene for small subunit ribosomal RNA (18S rRNA) of X-cells of the goby with PCR using universal primers. The gene that we obtained (DDBJ Accession no. AB451874) showed 91% sequence identity to that of the X-cells of the flathead flounder Hippoglossoid...

considering its gobiidea and feeding fish sturgeon caspian sea highest main and the need to fecundity this fish, this study was done in babolroud and tajan rivers in mazandaran. in order to conduct the study, 197 sand goby we were caught using an electros choker machine (v300-200) in the spring of 1390 ,which was the spawning season, at the tajan river (sari) and babolrood (babol). 103 fish whi...
