Population Growth00:57

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.

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.

Area of Science:

  • Marine biology
  • Conservation science
  • Spatial ecology

Background:

  • Humpback whale (Megaptera novaeangliae) populations are increasing in Western Australia.
  • Understanding space utilization is crucial for managing large ocean wildlife, especially in limited areas.

Purpose of the Study:

  • To determine the theoretical carrying capacity of a humpback whale resting area.
  • To assess how pod spacing behavior influences space use in aggregation areas.

Main Methods:

  • Two methods were used to estimate the nearest neighbor distance between whale pods.
  • Calculations were based on median nearest neighbor distances and a radius defining 50% population isolation.

Main Results:

  • Estimated pod spacing distances were 2.16 km and 1.93 km.
  • The resting area's carrying capacity was estimated at 1187–1482 whales at any given time.

Conclusions:

  • Whale pod spacing behavior dictates the number of individuals in limited aggregation areas.
  • Findings have implications for protected area boundaries and resource competition with human activities.
