We report sequence, tissue expression and map-position data for myogenin, MYOD1, myostatin and follistatin in three Ictalurid catfish species: channel catfish (Ictalurus punctatus), blue catfish (I. furcatus) and white catfish (Ameiurus catus). These genes are involved in muscle growth and development in mammals and may play similar roles in catfish. Amino acid sequences were highly conserved a...

Benecke1) was the first to report the isolation of Bacillus chitinovorus, a bacillus which decomposes chitin, from the sea water of Kiel Bay in 1905. Later, the bacillus was collected and studied mainly in Germany and in the United States, taking as sources various materials such as sea mud, sea water, fresh lake water, soil, compost, crustacea etc. However, the study of this bacillus has never...

Malawi is a landlocked country, stretching over 94 084 square kilometres of land and 24 404 square kilometres of fresh water, whose economic backbone is agriculture. Malawi’s HIV positivity rate is estimated at 10.0% (Table 1).1 HIV prevalence varies widely by geographic regions, where it is 14.5% in southern Malawi, 7.6% in central Malawi and 6.6% in northern Malawi. Prevalence also differs by...

Novel physical and chemical conditions of many modern ecosystems increasingly diverge from the environments known to have existed at any time in the history of Earth. The loss of natural land to urbanization is one of the most prevalent drivers of novel environments in freshwaters. However, current understanding of aquatic community response to urbanization is based heavily upon aggregate indic...
