Habitat Fragmentation02:31

Habitat Fragmentation

21.4K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

9.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Dietary Connections

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...

Standard Electrode Potentials

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

Potential Energy00:52

Potential Energy

42.7K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

Introduction to Connective Tissues01:11

Introduction to Connective Tissues

15.0K
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,...

Area of Science:

  • Wildlife ecology
  • Disease ecology
  • Conservation biology

Background:

  • Oral rabies vaccination (ORV) programs are vital for managing raccoon rabies.
  • Raccoon rabies epidemiology is influenced by landscape features, particularly in pine-dominated areas.
  • Understanding raccoon habitat suitability is critical for effective rabies surveillance and ORV planning.

Purpose of the Study:

  • To model raccoon habitat suitability in pine-dominated landscapes across Massachusetts, Florida, and Alabama.
  • To identify key environmental and landscape variables influencing raccoon distribution and potential rabies spread.
  • To inform raccoon rabies containment and elimination strategies through habitat connectivity analysis.

Main Methods:

  • Utilized the maximum entropy (Maxent) procedure to model raccoon habitat suitability.
  • Incorporated raccoon presence data and landscape/environmental variables (soil type, precipitation, temperature).
  • Employed Circuitscape to visualize habitat connectivity based on Maxent probability surfaces.

Main Results:

  • Soil type was the most influential variable in Alabama, linked to landcover and resource availability.
  • Precipitation and temperature emerged as key variables in Massachusetts and Florida, requiring further investigation.
  • Habitat connectivity maps were generated to identify potential corridors for rabies spread.

Conclusions:

  • Habitat suitability modeling provides valuable insights into raccoon rabies eco-epidemiology.
  • Identifying high-risk corridors can optimize ORV program planning and resource allocation.
  • Integrating these findings can lead to cost-effective rabies management strategies.
