phytoplankton and zooplankton modeling of pishin reservoir by means of an advection-diffusion drought model
phytoplankton and zooplankton concentrations in pishin reservoir are predicted employing a three-dimensional numerical model in this paper. modeling is performed using a numerical model based on mass transport equation. advection, diffusion and source/sink processes are considered as separate subroutines for predicting the concentrations of phytoplankton and zooplankton in the reservoir. finite...
متن کاملFitness and Optimal Body Size in Zooplankton Population
A measure of fitness which is an explicit function of feeding efficiency and vulnerability to predation is introduced. Feeding efficiency is a function of feeding and respiration rates and the nature of the food supply. Defining fitness as a function of body size reveals several potential explanations for the evolution of life-histories and for mechanisms of competition in zooplankton populatio...

متن کاملEarly is better: seasonal egg fitness and timing of reproduction in a zooplankton life-history model
Timing of reproduction influences future prospects of offspring and therefore the reproductive value of parents. Early offspring are often more valuable than later ones when food availability and predation risk fluctuate seasonally. Marine zooplankton have evolved a diversity of life history strategies in response to seasonality. We present a state-dependent life history model for the annual an...
متن کاملIncreased fitness of a key appendicularian zooplankton species under warmer, acidified seawater conditions
Ocean warming and acidification (OA) may alter the fitness of species in marine pelagic ecosystems through community effects or direct physiological impacts. We used the zooplanktonic appendicularian, Oikopleura dioica, to assess temperature and pH effects at mesocosm and microcosm scales. In mesocosms, both OA and warming positively impacted O. dioica abundance over successive generations. In ...
