Última Biodiversity and sustainable management of a tropical wetland lake ecosystem: A case study of Lake Kanyaboli, Kenya OceanDocs Rasowo, J.O.; Abila, R.; Manyala, J.. Lake Kanyaboli and the surrounding Yala swamp wetland has been recognized as an important biodiversity hotspot. Recent population genetic and phylogenetic studies confirm the evolutionary importance of Lake Kanyaboli (Kenya) in preserving the cichlid fish fauna of Lake Victoria. The adjoining Yala swamp harbours the endangered swamp antelope Sitatunga (Tragecephalus spekii) and several papyrus endemic birds. The lake and adjoining swamp play a critical role in the livelihood of the local communities who heavily depend on the wetland resources. Current ongoing large scale land use changes within the swamp threaten the ecological integrity and functioning of this highly dynamic wetland ecosystem. It is therefore imperative that proper management and...

Ano: 2006 URL: http://hdl.handle.net/1834/2126 The 2016 red tide crisis in southern Chile: Possible influence of the mass oceanic dumping of dead salmons ArchiMer Armijo, Julien; Oerder, Vera; Auger, Pierre-amaël; Bravo, Angela; Molina, Ernesto. In 2016, a massive harmful algal bloom (HAB) of Alexandrium catenella around Chiloé island caused one of the major socio-ecological crisis in Chilean history. This red tide occurred in two distinct pulses, the second, most anomalous, bursting with extreme toxicity on the Pacific coast, weeks after the highly controversial dumping off Chiloé of 4,700 t of rotting salmons, killed by a previous HAB of Pseudochattonella verruculosa. We study the transport of this pollution, analyzing the physical oceanographic conditions during and after the dumping. We find that a cyclonic gyre was present between the dumping site and the coast, visible in satellite altimetry and sea surface temperature data. Using Lagrangian simulations, we confirm that near-surface currents...

Ano: 2020 URL: https://archimer.ifremer.fr/doc/00593/70486/69183.pdf The effect of water Hyacinth, Eichhornia Crassipes, infestation on phytoplankton productivity in Lake Naivasha and the status of control OceanDocs Mironga, John Momanyi. The paper presents data collected in an assessment of effects of water hyacinth infestation on phytoplankton productivity in Lake Naivasha, Kenya. A summary of the status of control and strategies for the future is given. The ecological effects of water hyacinth, Eichhornia Crassipes, on Lake Naivasha have received little attention compared to the large body of work available on the weed’s socioeconomic impact on the country’s water ways and methods for its removal. This study was conducted to determine if water hyacinth infestation in Lake Naivasha affects phytoplankton productivity. Several sampling stations were set up in the lake at sites where the floating mats of the weed were present and sites where the weed was absent. Phytoplankton chlorophyll-a...
