Microtubule Associated Proteins (MAPs)01:42

Microtubule Associated Proteins (MAPs)

5.9K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

Plotting of Topographic Maps01:29

Plotting of Topographic Maps

525
Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...

Coordinates and Map Projections01:29

Coordinates and Map Projections

614
Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...

The Quantum-Mechanical Model of an Atom02:45

The Quantum-Mechanical Model of an Atom

57.3K
Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Area of Science:

  • Biogeography
  • Ecoregion classification
  • Mexican biodiversity

Background:

  • Mexico's diverse geography supports rich biodiversity.
  • Previous biogeographic studies lacked a unified provincial map.
  • Understanding provincial boundaries is crucial for conservation.

Purpose of the Study:

  • To delineate and map the 14 biogeographic provinces of Mexico.
  • To integrate climatic, geological, and biotic data for regionalization.
  • To provide digital data for future biogeographic research.

Main Methods:

  • Defined provinces based on recognized ecoregions.
  • Combined climatic, geological, and biotic criteria.
  • Created polygon shapefiles and raster data for all provinces.

Main Results:

  • Identified 14 biogeographic provinces across Nearctic, Neotropical, and transition zones.
  • Categorized provinces including Californian, Sonoran, Yucatán Peninsula, and Sierra Madre Oriental.
  • Developed comprehensive digital map files in vector and raster formats.

Conclusions:

  • The new map provides a standardized biogeographic framework for Mexico.
  • Digital data facilitates advanced spatial and temporal analyses.
  • This regionalization is essential for biodiversity research and conservation planning.
