Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems
Global ocean ecosystem dynamics zooplankton predators Marine ecosystems reproduction
2015/7/16
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental co...
Population Dynamics, Chick Diet, and Foraging Behavior of the Razorbill (Alca torda) at Matinicus Rock, Maine
source-sink dynamics diving, temperature-depth recorder
2015/1/4
During the summers of 2007-2009, I studied the population growth and reproductive and foraging ecology of the Razorbill (Alca torda) at Matinicus Rock (MR), Maine. This medium-sized marine bird in the...
Coupling methods for efficient simulation of spatial population dynamics
Coupling methods efficient simulation spatial population dynamics Populations and Evolution
2012/4/28
Coupling is a widely used technique in the theoretical study of interacting stochastic processes. In this paper I present an example demonstrating its usefulness also in the efficient computer simulat...
We study a complementarity game as a systematic tool for the investigation of the interplay between individual optimization and population effects and for the comparison of different strategy and lea...
A Verhulst-Like Two-Species Population Dynamics Model
Verhulst-Like Two-Species Population Dynamics Model
2010/11/15
The study of a two-species dynamics population model, which includes intraspecific competition to the Lotka-Volterra equation, is presented. Despite being simple, this model presents a very rich behav...
Scaling Function, Universality and Analytical Solutions of Generalized One-Species Population Dynamics Models
Scaling Function Universality Analytical Solutions Generalized One-Species Population Dynamics Models
2010/11/16
We consider several one-species population dynamics model with finite and infinite carrying capacity, time dependent growth and effort rates and solve them analytically. We show that defining suitable...
Generalized modeling of ecological population dynamics
Generalized modeling ecological population dynamics
2010/11/15
Over the past years several authors have used the approach of generalized modeling to study the dynamics of food chains and food webs. Generalized models come close to the efficiency of random matrix ...
Disrupted seasonal clockwork in the population dynamics of a freshwater copepod by climate warming
Disrupted seasonal clockwork the population dynamics freshwater copepod climate warming
2014/4/17
Life history responses are expected to accompany climate warming, yet little is known how long-term effects of climate and environmental change affect the seasonal dynamics of planktonic organisms. We...
Population dynamics of a freshwater calanoid copepod: Complex responses to changes in trophic status and climate variability
Population dynamics a freshwater calanoid copepod Complex responses changes in trophic status climate variability
2014/4/21
The long-term dynamics of the calanoid copepod Eudiaptomus gracilis were analyzed in Lake Constance, a deep lake that has been influenced strongly by changes in trophic status and climate variability ...

THE OPTIMAL CONTROL OF AGE-DEPENDENT POPULATION DYNAMICS BASED ON PARITY PROGRESSION
Optimal birth number control age-struct
2007/8/7
The optimal control problem for an age-dependent population dynamics basedon parity ratio progression is considered. The functional analytie approach of Dubovitskiiand Milyutin is adopted in the inves...
In this paper, we consider a closed Population system with n-intersections. It is proved that there exists a critical fertility distribution which leads to the stable population state. The existence a...
Mate finding, mating, and population dynamics in a planktonic copepod Oithona davisae: There are too few males
Mate finding mating population dynamics planktonic copepod Oithona davisae too few males
2014/4/22
Three-dimensional (3D) video observations of free-swimming copepods revealed the mechanisms of mate finding in the cyclopoid copepod Oithona davisae (cephalothorax length 0.33 mm). The females are amb...
