Ecological Niches02:02

Ecological Niches

27.5K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Optimal Foraging00:48

Optimal Foraging

14.3K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Mechanistic Models: Compartment Models in Individual and Population Analysis

340
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...

Quantifying and Rejecting Outliers: The Grubbs Test01:02

Quantifying and Rejecting Outliers: The Grubbs Test

5.0K
Sometimes, a data set can have a recorded numerical observation that greatly  deviates from the rest of the data. Assuming that the data is normally distributed, a statistical method called the Grubbs test can be used to determine whether the observation is truly an outlier.  To perform a two-tailed Grubbs test, first, calculate the absolute difference between the outlier and the mean. Then, calculate the ratio between this difference and the standard deviation of the sample. This...

Cluster Sampling Method01:20

Cluster Sampling Method

15.7K
Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...

Conservation of Small Populations02:04

Conservation of Small Populations

17.7K
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:

  • Ecology
  • Biogeography
  • Computational Biology

Background:

  • Ecological niche modeling is crucial for understanding species distribution and conservation.
  • Presence-only data presents a significant challenge in ecological niche modeling.
  • Existing methods struggle to accurately model niches with limited comparative data.

Purpose of the Study:

  • Introduce a novel presence-only ecological niche modeling method: range bagging.
  • Extend the concept of environmental range to multi-dimensional spaces.
  • Demonstrate the computational feasibility and interpretability of range bagging.

Main Methods:

  • Developed range bagging, inspired by ensemble learning algorithms.
  • Extended the species' environmental range concept to multiple dimensions.
  • Analyzed computational complexity, showing linear scalability with data size.

Main Results:

  • Range bagging effectively models ecological niches from presence-only data.
  • The method is computationally efficient, even with high-dimensional environmental data.
  • The base learner targets ecologically interpretable properties of species' biological requirements.

Conclusions:

  • Range bagging offers a viable solution for presence-only niche modeling.
  • The method has potential applications in one-class classification tasks beyond ecology.
  • This approach advances ecological niche modeling and related computational biology fields.
