Little bustard Little bustard The little bustard ("Tetrax tetrax") is a large bird in the bustard family, the only member of the genus Tetrax. The genus name is from Ancient Greek and refers to a gamebird mentioned by Aristophanes and others. It breeds in southern Europe and in western and central Asia. Southernmost European birds are mainly resident, but other populations migrate further south in winter. The central European population once breeding in the grassland of Hungary became extinct several decades ago. This species is declining due to habitat loss throughout its range. It used to breed more widely, for example ranging
Edwardsiella tarda along with maintaining suitable sanitation of water. Other stress factors include drastic changes in temperature, pH, and dissolved oxygen levels in the water. In order to manage properly for edwardsiellosis water must be checked constantly in order to keep fish stocks completely free of pathogens. Some of the most recent research done on "Edwardsiella tarda" was performed by Griffin et al. (2013) to assess what the literature refers to as "the intra-specific variability of "E. tarda" isolates from 4 different fish species in the eastern United States." These intra-specific variations that they were looking for occur in other parts of
