Summary
Repurposing vacant urban land can create ecological corridors, linking habitats and enhancing ecosystem services. This approach balances development needs with conservation, improving green space networks in cities.
Area of Science:
- Urban ecology
- Landscape planning
- Conservation science
Background:
- Storm surge protection enables development in flood-prone areas, leading to habitat fragmentation.
- Urban areas possess vacant land, offering opportunities for green space enhancement and ecological restoration.
Purpose of the Study:
- To develop a regional growth framework balancing vacant land repurposing with ecosystem service provision.
- To maximize landscape connectivity by utilizing vacant land for ecological linkages.
Main Methods:
- Utilized raster-based suitability models in ArcGIS to assess vacant land development potential and ecological value.
- Employed a least cost path connectivity model (Linkage Mapper) to link high-ecological-value vacant lands, creating ecological corridors.
Main Results:
- Identified vacant lands with low development potential and high ecological value as key for creating ecological corridors.
- Demonstrated that repurposing vacant land can connect existing ecological patches with minimal impact on development potential.
- Showcased enhanced provision of ecosystem services through strategic vacant land utilization.
Conclusions:
- Vacant urban land offers a viable strategy for establishing ecological corridors and improving green infrastructure.
- The proposed framework provides a model for ecologically informed urban land repurposing.
- Balancing development and conservation through vacant land management can mitigate habitat fragmentation and enhance urban biodiversity.

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

01:11Introduction to Connective Tissues
15.1K
Connective tissues are one of the four main tissue types in humans that are extensively present in the body. They are characterized by cells embedded in an extracellular matrix (ECM) composed of a ground substance and three main types of protein fibers— collagen, elastic, and reticular fibers. The ground substance of connective tissues can range from a watery and jelly-like consistency to mineralized and hard. The wide variety of cells in the connective tissues include fibroblasts,...

01:30Classification of Connective Tissues
16.1K
The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....

6.6K
During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development.

Dense connective tissue contains more collagen fibers than loose connective tissue. As a consequence, it displays greater resistance to stretching. There are two major categories of dense connective tissue— regular and irregular.
Dense Regular Connective Tissue
In dense regular connective tissue, fibers are arranged parallel to each other, enhancing its tensile strength and resistance to stretching in the direction of the fiber orientations. Ligaments and tendons are made of dense regular...
