The Life of Inland Waters

“the effect of risk aversion on the demand for life insurance: the case of iranian life insurance market”

abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...

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...

Comparison of the Envisat Waveform Retrackers over Inland Waters

Since the launch of ENVISAT satellite in 2002, the Radar Altimetry Mission provides systematic altimeter observations of the Earth surface. The ENVISAT Geophysical Data Records products contain, over all type of surfaces, altimeter ranges derived from four specialized retrackers: Ocean, Ice-1, Ice-2 and Sea-Ice retracker. Among the different goals of the ENVISAT Mission, one directly concerns l...

Copepod reproductive strategies: life-history theory, phylogenetic pattern and invasion of inland waters

Life-history theory predicts that different reproductive strategies should evolve in environments that differ in resource availability, mortality, seasonality, and in spatial or temporal variation. Within a population, the predicted optimal strategy is driven by tradeoffs that are mediated by the environment in which the organisms live. At the same time, phylogenetic history may circumscribe na...
