Fluctuating Fisheries in Africa's Inland Waters: Well

This paper evaluates evidence that fish stocks in Africa's inland waters are climate-driven and cannot be stabilized by conventional fisheries management measures. We draw on published material and our own recent and on-going research in Lake Chad and the East African Great Lakes area to propose that fisherfolk's livelihood strategies are well adapted to both seasonal and inter-annual climate-i...

Invasive molluscs in Umbrian inland waters: ecological and reproductive aspects

Invasive molluscs in Umbrian inland waters: ecological and reproductive aspects The increasing colonisation by aquatic invasive molluscs has only recently received scientific attention in Umbria, notwithstanding the possible great impact on the functionality and biodiversity of the freshwater ecosystems. The present contribution highlights the results of investigations carried out on Dreissena ...

Role of Cl channels in Cl-dependent Na/H exchange.

A novel Na/H exchange activity that requires Cl was recently identified in the apical membrane of crypt cells of the rat distal colon. This study explores the nature of the coupling of Cl and Na/H exchange. A concentration of 100 μM 5-nitro-2-(3-phenylpropylamino)benzoic acid, a Cl channel blocker, inhibited the Cl dependence of both proton gradient-driven22Na uptake from crypt cell apical memb...

Reflectance Models for Quantifying Chlorophyll in Inland Waters

To develop the models for chlorophyll (CHL) estimation, the nature of a peak near 700 nm on the reflectance spectrum of water should be investigated. Simultaneous measurements of the reflectance spectra from 400 to 750 nm and relevant water quality constituent concentrations were carried out. A shift of the peak position and an increase of the peak magnitude, when chlorophyll concentration incr...
