North Carolina coastal flooding worsening climate change population growth
2019/10/22
A historic 120-year-old data set is allowing researchers to confirm what data modeling systems have been predicting: climate change is increasing precipitation events like hurricanes, tropical storms ...

Determinants of Population Growth in Rajasthan: An Analysis
Determinants of Population Rajasthan Analysis
2011/1/17
Rajasthan is the biggest State of India and is currently in the second phase of demographic
transition and is moving towards the third phase of demographic transition with very slow
pace.
Interactions between limiting nutrients: Consequences for somatic and population growth of Daphnia magna
Interactions between limiting nutrients population growth of Daphnia magna
2014/4/17
To assess the significance of nutrient interactions on animal performance, life-history experiments were
conducted with the freshwater herbivore Daphnia magna in a system with two limiting nutrients ...
Effect of fully characterized unsteady flow on population growth of the dinoflagellate Lingulodinium polyedrum
characterized unsteady dinoflagellate Lingulodinium polyedrum
2014/4/18
Dinoflagellate population growth is inhibited by fluid motion, which is typically characterized by some average
flow property, regardless if the flow is steady or unsteady. This study compares the ef...
The dynamics of the Ramsey economic growth model with the von Bertalanffy population growth law
Ramsey model population models
2010/9/14
One of the key elements in economic growth theory is that population growth exponentially. In this paper we reformulate the Ramsey model of economic growth by assuming that the law describing populati...
BOUNDEDNESS,ASYMPTOTIC BEHAVIOR AND OSCILLATORY PROPERTIES FOR THE MODELS OF SINGLE-SPECIES POPULATION GROWTH WITH IMPULSIVE EFFECT
Impulse differential equations
2007/12/11
In this paper, we obtain the boundedness, asymptotic behavior and oscillatory properties for the single logistic models with impulse effect. Some examples are given to indicate the application of our ...
The Effect of Dispersal on Population Growth with Stage-structure
patch environment stage-structure pollution
2007/12/10
The effect of dispersal on the permanence of population in a polluted patch is studied in this paper. The authors constructed a single-species dispersal model with stage-structure in two patches. The ...
TIME-DEPENDENT COOPERATIVE SYSTEM OF POPULATION GROWTH
Cooperative system globally attractive
2007/8/7
In this paper, we consider the asymptotic behavior of a general time-dependent cooperative system. Sufficient condition is obtained for the existence of a globally attractive positive periodic solutio...
In recent years, population growth models with spatial diffusion have been extensively studied by many authors (for example, see [1-5]). In this paper, a population growth model is considered with a d...
Effects of cyanobacterial toxicity and morphology on the population growth of freshwater zooplankton: Meta-analyses of laboratory experiments
cyanobacterial toxicity morphology on the population growth freshwater zooplankton laboratory experiments
2014/5/4
We synthesized data from 66 published laboratory studies, representing 597 experimental comparisons, examining the effects of cyanobacterial toxicity and morphology on the population growth rate and s...
Effect of turbulence on sedimentation and net population growth of the dinoflagellate Ceratium tripos and interactions with its predator, Fragilidium subglobosum
Effect of turbulence on sedimentation and net population growth of the dinoflagellate Ceratium tripos and interactions with its predator, Fragilidium subglobosum
2014/5/13
We investigated the effect of natural levels of turbulence on the vertical distribution and net population growth of the dinoflagellate Ceratium tripos and on the interaction with its predator, the mi...
Effect of fluid shear and irradiance on population growth and cellular toxin content of the dinoflagellate Alexandrium fundyense
fluid shear irradiance population growth cellular toxin content dinoflagellate Alexandrium fundyense
2014/6/9
The potential for in situ turbulence to inhibit dinoflagellate population growth has been demonstrated by experimentally exposing dinoflagellate cultures to quantified shear flow. However, despite int...
