Estudio de la calidad de las aguas del Estero del Muerto en base a la concentración de oxígeno disuelto.- Estación fija
Provedor de dados: 20
Autores: Valencia, M.; Burgos, L.; de Espinoza, M.
Se presenta un análisis de la influencia de la marea y profundidad sobre la concentración de oxígeno disuelto en aguas del Estero del Muerto, Provincia del Guayas. Se establece que existe una relación directa de estos dos factores sobre la msima. Se encuentra mayor concentración de oxígeno disuelto en superficie, la cual disminuye conforme aumenta la profundidad, siendo mayor durante el flujo que durante el reflujo; existe un leve incremento durante la noche como producto de la agitación de las aguas por acción del viento. En forma general se concluye que existen condiciones de oxígeno en el área, lo que indica problemas de contaminación del estero.

Preliminary Assessment of the Ecological Status of Godineau Swamp: Establishing a Socio-Economic Baseline
Provedor de dados: 20
Autores: Clarke-Marshall, M.; Ghouralal, N.
Human activities adjacent to and within a wetland, influence its ecological status. An understanding of the social and economic conditions in the communities within and adjacent to the Godineau Swamp is fundamental to its sustainable use. The effective functioning of wetland resources is centered on the sustainable management of human activities and traditional uses. The Godineau Swamp is the second largest wetland system found on the Gulf of Paria of Trinidad. Traditionally the wetland has supported a fish and shellfish industry and provided land for agriculture livestock farming and housing. Oil exploration has taken place in the Godineau Swamp for the last fifty years and the Swamp continues to provide several opportunities for ecotourism.

The role of the Yala swamp lakes in conservation of Lake Victoria region haplochromine cichlids: evidence from molecular genetic and trophic ecology studies
Provedor de dados: 20
Autores: Abila, R.; Salzburger, W.; Ndonga, M.F.; Owiti, D.O.; Barluenga, M.
Lake Kanyaboli (Kenya), a satellite lake of Lake Victoria, has been suggested as a potential refugium for haplochromine cichlids that have gone extinct in Lake Victoria. We employed mitochondrial DNA and microsatellite DNA molecular markers as well as feeding ecology studies to re- evaluate the evolutionary and ecological significance of Lake Kanyaboli haplochromines. The mitochondrial DNA and microsatellite markers revealed high genetic diversity in the endangered Xystichromis phytophagus and also the presence of mtDNA haplotypes that may have either gone extinct in Lake Victoria or have arisen in situ. Lake Kanyaboli thus acts as a ‘genetic reservoir’ for the Lake Victoria species flock. Gut content analysis revealed six trophic groups among the six...
