African Journal of Aquatic Science (Afr J Aquat Sci)

Publisher: Taylor & Francis

Journal description

The African Journal of Aquatic Science is an international journal devoted to the study of the aquatic sciences, covering all African waters. The Journal publishes peer-reviewed original scientific papers and short articles in all the aquatic science fields including limnology, hydrobiology, estuarine and coastal marine science. Amongst the topics covered in this Journal are ecology, conservation, bio-monitoring, management, water quality, ecotoxicology, biological interactions, physical properties and human impacts on aquatic systems. Supported by the Southern African Society of Aquatic Scientists, the African Journal of Aquatic Science serves as an indispensable reference source for those interested in understanding the dynamics affecting the valuable aquatic resources of Africa.

    ABSTRACT: Phytoplankton community structure and physico-chemical variables, sampled monthly at an offshore station in Lake Hora-Kilole from August 2007 to May 2008, were compared with previously reported data. In 1989 the Mojo River was temporarily diverted to flow into the lake. The lake subsequently changed markedly, first from being a small polymictic system to being a large monomictic system with a maximum depth of 29 m in 1990/1991, and then by 2007/2008 to again being a small continuously polymictic system less than 8 m deep. Secchi depth averaged 0.35 m and varied from 0.15 to 0.78 m, indicating a marked decline in water transparency from the levels recorded in 1990/1991. Nitrate levels, rarely detectable in the 1960s, subsequently became high, whereas phosphorus levels have declined since the 1960s. The phytoplankton community was dominated by cyanobacteria and dinoflagellates, in contrast to the dominance by cyanobacteria before 1989, and by dinoflagellates and chlorophytes shortly thereafter. Total phytoplankton Chl a averaged 83.5 mg m−3 and ranged from 36 to 148 mg m−3, peaking in October 2007 and February 2008. The impacts of river diversion and shoreline modification on the lake were reflected in changes in the physico-chemical conditions, including low light penetration and high nitrate, and changed phytoplankton community structure. The development of algal blooms in future is anticipated.

    ABSTRACT: Soluble reactive silica (SRSi) concentrations and diatom abundance were determined during four surveys in the Tanzanian waters of Lake Victoria between 2005 and 2008. The SRSi concentrations increased towards offshore sites, while the opposite was true for diatom abundance. The water directly above the sediment had higher concentrations of SRSi (1.17 ± 0.68 mg l−1) than surface waters (0.79 ± 0.29 mg l−1). The SRSi concentrations in the lake were low compared to those in the period preceding the 1980s. Increased uptake, decreased dissolution and increased accumulation in the sediments are the major contributing factors. The high bottom and low surface concentrations of SRSi are accounted for by increased SRSi uptake by the highly abundant surface diatom communities and their increased sinking rate. The change in diatom species composition and abundance, leading to the dominance of robust and opportunistic species, is probably accelerated by the increased eutrophication and pollution of the lake water.

    ABSTRACT: Baseline community assemblages and diversity of macrozoobenthic infauna in soft-bottomed intertidal flats at Bodo Creek on the upper reaches of the Andoni–Bonny estuarine system were determined spatially and in relation to sediment particle characteristics for two years from May 2006 to April 2008. Interstitial water temperature, pH, dissolved oxygen and conductivity varied, while biological oxygen demand at the sites was similar. A total of 7 742 specimens belonging to 47 genera and 29 families of macrofauna were recovered from the samples. Density ranged between 8 and 1 583 m−2, while Shannon–Wiener diversity varied from 0.102 to 1.052. A Hutcheson t-test revealed significant inter-site diversity differences, except for Station 2 vs Station 5 and Station 4 vs Station 5. Canonical correspondence analysis (CCA) revealed that the nature of substratum accounted for 34% of the taxa distribution and abundance in the study area; variances for the first and second axes were 77.8% and 21.2%, respectively. The CCA ordination showed that Callianassa sp., Upogebia furcata and Keletistes rhizoecus were uniquely associated with Station 1 and were greatly influenced by the amount of silt and clay. Complementary roles of other physico-chemical parameters, as well as biological interactions in structuring the zoobenthic communities, were detected. The data are a potential baseline for measuring the degree of recovery following two recent oil spills.
