Population Growth

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Ecological Disturbance

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Oscillations about an Equilibrium Position

Oscillations about an Equilibrium Position

Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Damped Oscillations

Damped Oscillations

In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

Area of Science:

Mathematical biology
Ecological modeling
Population dynamics

Background:

The Fisher-Kolmogorov-Petrovsky-Piskunov (FKPP) equation models population spread.
Ecological landscapes can exhibit spatial variations impacting population growth and distribution.
Understanding population responses to environmental heterogeneity is crucial for ecological studies.

Purpose of the Study:

To investigate how ecological landscape disturbances affect population spatial distribution.
To characterize stationary profiles resulting from population evolution under the nonlocal FKPP equation near environmental variations.
To explore how landscape heterogeneities can unveil information about population dynamics.

Main Methods:

Numerical simulations of the nonlocal FKPP equation.
Analytical techniques to characterize population profiles.
Analysis of the interaction kernel's influence on spatial distribution patterns.

Main Results:

Identified three types of stationary profiles: sustained oscillations, decaying oscillations, and exponential relaxation.
Demonstrated that the interaction kernel dictates the type of stationary profile formed.
Showcased how landscape wrinkles induced by heterogeneities map to the interaction kernel's shape.

Conclusions:

Environmental disturbances create distinct population distribution patterns.
Population dynamics near environmental changes are predictable through the FKPP equation.
Heterogeneous landscapes offer insights into population interactions and evolution that uniform landscapes obscure.
