Long range vertical migration of Volvox in tropical Lake Cahora Bassa (Mozambique)

Domesticating a white elephant: sustainability and struggles over water, the case of Cahora Bassa Dam.

This article explores the socio-economic and environmental impact ofCahora Bassa Dam and South Africa s destabilisation campaign on the communities and ecology of the Zambezi River valley in Mozambique. It argues that the historical memories and lived experiences of these riverine communities provide important insights into the history of the area and must take centre stage in any scholarly ana...

Bayesian Methods in Reservoir Operations : TheZambezi River

This paper describes a general Bayesian methodology for reservoir operations. This methodology is applied to the operation of the two main reservoirs in the Zambezi river: Lake Kariba and Cahora Bassa.

Long-term changes in the diel vertical migration

Samples historically collected and analysed by the Continuous Plankton Recorder survey were used to examine long-term (1958 to 1994) patterns in the normal diel vertical migrat~on (NDVM) behaviour of 7 copepod taxa in the North Sea: Calanus finmarchicus C5-C6; Calanus spp. Cl-C4; Cenlropages typicus; Centropages hamatus; Temora longicornis; Acartia clausii and Para-Pseudocalanus (this last grou...

Vertical Structure of Tropical

Diel vertical migration in the Lake Superior pelagic community. I. Changes in vertical migration of coregonids in response to varying predation risk

The distribution of fishes is influenced by a host of physico-chemical and biological variables, including temperature and oxygen, prey abundance, feeding or assimilation rates, and predation risk. We used hydroacoustics and midwater trawls to measure the vertical distribution of pelagic fishes during a series of research cruises on Lake Superior’s western arm in 2001 and 2004. Our objective wa...
