Growth Models with Integration: Problem Solving

81
In population modeling, integration provides a systematic way to determine accumulated quantities from known rates of change. One such application arises in ecology, where the total weight of a fish population in a body of water is referred to as its biomass. When the rate of growth of this biomass is known as a function of time, calculus can be used to determine the total biomass at a future date.Growth Rate and Biomass FunctionLet the growth rate of the fish population be represented by a...

Mechanistic Models: Compartment Models in Individual and Population Analysis

310
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Analysis of Population Pharmacokinetic Data

880
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

Conservation of Small Populations02:04

Conservation of Small Populations

17.6K
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...

Area of Science:

  • Conservation Biology
  • Population Ecology
  • Wildlife Management

Background:

  • Amphibian populations are declining globally, necessitating reintroduction programs.
  • Adaptive management is crucial for these programs due to population uncertainties and recurring decisions.
  • Estimating demographic rates for amphibians is challenging due to sparse, life-stage-specific monitoring data.

Purpose of the Study:

  • To develop and evaluate a novel parameterization for integrated population models tailored to amphibian reintroduction ecology.
  • To utilize relatively inexpensive monitoring data for estimating demographic rates and supporting decision-support models.
  • To assess the Oregon spotted frog's population dynamics post-reintroduction in the Klamath Basin.

Main Methods:

  • Developed a new integrated population model parameterization for amphibians.
  • Applied the model to Oregon spotted frog (Rana pretiosa) monitoring data (2007-2014).
  • Estimated demographic rates including survival probabilities across life stages and reproductive output.

Main Results:

  • Oregon spotted frog populations showed increased egg masses and adult/metamorph abundances post-reintroduction.
  • Egg-to-metamorph survival varied (0.01-0.09), not linked to temperature.
  • Metamorph-to-adult survival (0.13-0.86) positively correlated with mean monthly temperatures.
  • Adult survival was lower for founders (0.40) than recruits (0.56).
  • Mean egg masses per adult female was 0.74.

Conclusions:

  • The study provides the first wild estimates of Oregon spotted frog egg-to-metamorph and metamorph-to-adult transition probabilities.
  • The integrated population model framework effectively accommodates uncertainty and integrates diverse datasets for amphibian management.
  • This modeling approach serves as a foundation for amphibian decision-support models within adaptive management programs.
