Plasticity in life-history traits.
We describe the impact of recent life-history plasticity theory on insect studies, particularly on the interface between genetics and plasticity. We focus on the three-dimensional relationship between three key life-history traits: adult size (or mass), development time and growth rate, and the connections to life cycle regulation, host plant choice, and sexual selection in seasonal environment...
متن کاملPomacea canaliculata (Gastropoda: Ampullariidae): life-history traits and their plasticity.
Freshwater snails belonging to the Ampullariidae family show noteworthy anatomical, physiological and ecological characteristics (Berthold, 1991), which have captivated scientific interest since long ago. However, few field studies have focussed on apple snail population dynamics (Burky, 1974; Lum Kong and Kenny, 1989). International concern about the Argentinean apple snail Pomacea canaliculat...
متن کاملPhytoremediation of cyanophos insecticide by Plantago major L. in water
Cyanophos is commonly used in Egypt to control various agricultural and horticultural pests. It is not easily hydrolyzed and thus they are highly persistent and accumulate in various aquatic compartments such as rivers and lakes. Such issues may be solved by phytoremediation, which is the use of plants for the cleanup of pollutants. Here, we tested Plantago major L. to clean water polluted with...
متن کاملsecuritization of mortality risks in life annuities
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
