Characterization of tropical freshwater; River Ogun, Lagos Nigeria
Tropical Freshwater Biology, 2020Physico-chemical parameters and microbial contents of Ogun River at Magodo area, Lagos were investigated in relation to its safety for consumption. Water samples were weekly collected between August and December, 2016 at three equi-distance intervals for analysis on physico-chemical parameters, total bacterial count and biochemical tests following ...

Fish mercury increase in Lago Manso, a new hydroelectric reservoir in tropical Brazil
Journal of Environmental Management, 2006It has been frequently demonstrated that mercury (Hg) concentrations in fish rise in newly constructed hydroelectric reservoirs in the Northern Hemisphere. In the present work, we studied whether similar effects take place also in a tropical upland reservoir during impoundment and discuss possible causes and implications.

Hydrobiologia, 2004
The limnology of Lago Biao and Lago Loreto, two tropical crater lakes on the island of Bioko, was investigated for the first time in January of 2002. Lago Biao fills a caldera at 1750 m altitude and is 18.5 m deep. This lake was characterized by low conductivity (11.6-13.3 μS cm−1), low pH (5.9-6.2), an oxycline between 6 and 10 m depth (90-27 ...

Herbivory in a fragmented tropical forest: patterns from islands at Lago Gatún, Panama
Biodiversity & Conservation, 2002By imposing density-dependent mortality upon their hosts, specialistinsect herbivores are thought to contribute to the maintenance of tree diversityin tropical forests. Forest fragmentation may alter patterns of herbivory,however, which may have important implications for tree species diversity inforest remnants.

Recent changes in molluscan species diversity of a large tropical lake (Lago de Peten, Guatemala)1
Limnology and Oceanography, 1976The relative and absolute shifts in abundance of five species of freshwater gastropods appear to reflect widespread changes in the drainage basin around Lago de Peten. Fluctuations in the number of shells deposited in 3.7 m of lake sediments are not directly correlated with changes in preserved organic matter or major cations (calcium, magnesium, and ...
