Long-patch Base Excision Repair01:02

Long-patch Base Excision Repair

7.1K
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Patch Clamp01:18

Patch Clamp

5.6K
Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...

Ecological Niches

24.1K
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.

Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Habitat Fragmentation02:31

Habitat Fragmentation

17.7K
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.

Buffers: Overview01:30

Buffers: Overview

4.6K
Buffers play a crucial role in stabilizing the pH of a solution by mitigating the effects of small amounts of added acid or base. They consist of a weak acid and its conjugate base or a weak base and its conjugate acid. A solution of acetic acid and sodium acetate is an example of a buffer that consists of a weak acid and its salt: CH3COOH (aq) + CH3COONa (aq). An example of a buffer that consists of a weak base and its salt is a solution of ammonia and ammonium chloride: NH3 (aq) + NH4Cl (aq).

Area of Science:

  • Ecology
  • Evolutionary Biology
  • Ecosystem Dynamics

Background:

  • Ephemeral resource patches (ERPs) like dung and carrion are widespread but lack clear definition.
  • Their dynamics significantly influence ecosystem heterogeneity and organism evolution.
  • Previous research has not synthesized ERPs' spatiotemporal characteristics or broad ecological impacts.

Purpose of the Study:

  • To define Ephemeral Resource Patches (ERPs) based on specific criteria.
  • To identify shared spatiotemporal characteristics of ERPs.
  • To synthesize literature on ERPs' ecological and evolutionary influences and propose a unifying framework.

Main Methods:

  • Defining ERPs by homogeneity, discrete multitrophic communities, and inability to balance depletion/renewal.
  • Outlining 12 spatiotemporal characteristics of ERPs.
  • Synthesizing existing literature on ERP dynamics and ecological/evolutionary theory.

Main Results:

  • A clear definition for ERPs is established.
  • Twelve spatiotemporal characteristics for ERPs are proposed.
  • A conceptual framework is presented detailing ERPs' role in shaping adaptive trajectories and ecosystem structure.

Conclusions:

  • ERPs are vital for ecosystem heterogeneity and organism evolution.
  • The proposed framework integrates ERP dynamics into ecological and evolutionary theory.
  • Future research on resource variation and interactions is recommended for biodiversity management and conservation.
