Does the exclusion of meiofauna affect the estimation of biotic indices using stream invertebrates?

Mbaka, John Gichimu; M’Erimba, Charles M; Karanja, Henry T; Mathooko, Jude M; Mwaniki, Mercy W (Taylor & Francis, 2016)

Biomonitoring of rivers is usually undertaken using information based on macroinvertebrate assemblages. However, exclusion of meiofauna (i.e. invertebrates less than 0.5 mm in size) when sorting benthic invertebrates can ...

Monitoring water and habitat quality in six rivers draining the Mt. Kenya and Aberdare Catchments using Macroinvertebrates and Qualitative Habitat Scoring

Mmerimba, Charles M; Mathooko, Jude M; Karanja, H.T; Mbaka, John Gichimu (2014)

The study was conducted in June and September 2011 in six rivers that drain Mt. Kenya and the Aberdare catchments, i.e. Honi, Naro Moru, Liki, Sirimon, Mariara and Karigu. The main objective was to determine the ecological ...

Effect of drift sampler exposure time and net mesh size on invertebrate drift density in the Njoro River, Kenya

Mureithi, Priscilla W; Mbaka, John Gichimu; M’Erimba, Charles M; Mathooko, Jude M (Taylor & Francis, 2018)

Although invertebrate drift is an important ecological process in lotic ecosystems, very little is known about it in Kenyan rivers. The primary aim of this study was to investigate the effect of driftnet mesh size and ...

Benthic Macro-invertebrate Diversity and Biomass Distribution in Relation to Canopy Cover and Organic Matter in River Njoro, Kenya

Mbaka, John Gichimu; Mathooko, Jude M; M'Erimba, Charles Mwithali (Egerton University, 2013)

Field experiments to quantify benthic macroinvertebrate density, diversity and biomass and benthic organic matter (BOM) content in the River Njoro, Kenya, were conducted between January 2009 and April 2009 at four sites ...
