Temporal dynamics of phytoplankton communities and their responses to environmental factors in Grand-Lahou Lagoon, Ivory Coast, West Africa

Variations in physical-chemical factors, species composition, abundance and biomass of phytoplankton assemblages, as well as their responses to environmental factors, were investigated in Grand-Lahou Lagoon from June 2006 to February 2007 (Ivory Coast, West Africa). The hydrosystem and the growth of anthropogenic activities on its hillsides particularly favored the high rate of soluble reactive phosphate […]

Foraging and pollination activity of Musca domestica L. (Diptera: Muscidae) on flowers of Ricinus communis L. (Euphorbiaceae) at Maroua, Cameroon

To evaluate the impact of Musca domestica on fruit and seed yields of Ricinus communis, its foraging and pollinating activity were studied in Maroua, during two seasons of flowering (September – November 2010 and 2011). Treatments included unlimited inflorescences access by all visitors, bagged inflorescences to avoid all visits, and limited visits of M. domestica. […]

Foraging and pollination activity of Macronomia vulpina (Gerstaecker, 1857) (Hymenoptera: Halictidae) on Gossypium hirsutum L. (Malvaceae) flowers at Maroua, Cameroon

To evaluate the impact of Macronomia vulpina (Hymenoptera: Halictidae) on bolls and seeds of Gossypium hirsutum, its foraging and pollinating activities were studied in Maroua, during two seasons of flowering (August-October 2010 and 2011). Treatments included unlimited flowers access by all visitors, bagged flowers to avoid all visits and limited visits of Macronomia vulpina. Observations […]
