Summary
This study enhances the landscape mosaic model to map land use changes and anthropic threats. The improved model offers better quantitative reporting and visualization of landscape dynamics over time.
Area of Science:
- Environmental Science
- Geographic Information Science
- Spatial Analysis
Background:
- The landscape mosaic model quantifies land use juxtaposition and anthropic threats.
- Spatial-temporal shifts in the landscape mosaic indicate changes in human impact.
- Previous models lacked flexible reporting and detailed temporal trend analysis.
Purpose of the Study:
- To refine the landscape mosaic model for improved quantification and mapping of land use.
- To introduce a heatmap scheme for enhanced thematic and quantitative reporting.
- To investigate land cover changes and anthropic intensity at various scales.
Main Methods:
- Utilized U.S. Geological Survey National Land Cover Database (NLCD) for 2001 and 2021.
- Derived landscape mosaics at five analysis scales.
- Implemented a novel heatmap scheme for data visualization and analysis.
Main Results:
- The enhanced model effectively maps land use patterns and changes.
- Heatmaps provide detailed insights into anthropic intensity and temporal trends.
- Results are exemplified for the Atlanta metropolitan area, showcasing thematic features.
Conclusions:
- The revised landscape mosaic model offers improved analytical capabilities.
- Potential applications span ecology, landscape planning, and restoration efforts.
- All assessment tools are available in open-source software packages.

The Fluid Mosaic Model
146.9K
The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

Multicompartment Models: Overview
134
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Three-Compartment Open Model
204
The three-compartment open model is a pharmacokinetic model used to describe the distribution and elimination of drugs following extravascular administration. It comprises a central compartment representing the plasma and two peripheral compartments. The highly perfused peripheral compartment represents organs and tissues with a rich blood supply, such as the liver, kidneys, and lungs. The scarcely perfused peripheral compartment represents tissues with lower blood supply, such as adipose...
