What is Biodiversity?01:19

What is Biodiversity?

33.2K
Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

Threats to Biodiversity

26.7K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Biodiversity and Human Values

16.7K
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Ogive Graph01:07

Ogive Graph

6.7K
An ogive graph is sometimes called a cumulative frequency polygon. It is one type of frequency polygon that shows cumulative frequency. In other words, the cumulative percentages are added to the graph from left to right. An ogive graph plots cumulative frequency on the vertical y-axis and class boundaries along the horizontal x-axis. It’s very similar to a histogram; only instead of rectangles, an ogive displays a single point where the top right of the rectangle would be. Creating this...

Graphing Antiderivatives01:30

Graphing Antiderivatives

52
The concept of an antiderivative is fundamental in calculus, describing how a function's values accumulate over time. This process is closely related to physical motion, such as the movement of a rolling ball. As the ball progresses, its position changes in response to variations in velocity, just as an antiderivative graph reflects the cumulative effect of the original function's values.Graphing an antiderivative requires interpreting how a function's values influence the shape of its...

Bar Graph01:07

Bar Graph

21.5K
A bar graph is also called a bar chart and consists of bars that are separated from each other. It either uses horizontal or vertical bars to show comparisons among categories. The bars can be rectangles, or they can be rectangular boxes (used in three-dimensional plots). One axis of the graph represents the specific categories being compared, and the other axis shows a discrete value. In this graph, the length of the bar for each category is proportional to the number or percent of individuals...

Area of Science:

  • Biodiversity informatics
  • Data science
  • Zoology

Background:

  • Vast amounts of biodiversity data are increasingly available online but often remain in isolated databases.
  • Integrating these disparate data sources is crucial for comprehensive biodiversity research and conservation efforts.
  • Local, database-specific identifiers hinder data interoperability and the creation of unified knowledge bases.

Purpose of the Study:

  • To explore the feasibility of creating a unified biodiversity knowledge graph for Australian fauna.
  • To develop methods for mapping local identifiers to shared global identifiers for enhanced data integration.
  • To demonstrate the application of such a knowledge graph in analyzing taxonomic publication trends.

Main Methods:

  • Data cleaning and reconciliation of diverse biodiversity datasets.
  • Mapping of local identifiers to shared global identifiers.
  • Construction of a knowledge graph integrating entities like taxa, publications, and specimens.
  • Development of a web interface (Ozymandias) for knowledge graph exploration.

Main Results:

  • Successfully constructed a biodiversity knowledge graph for Australian fauna.
  • Detailed description of data cleaning and reconciliation processes.
  • Demonstrated the utility of the knowledge graph for analyzing changes in taxonomic publication patterns over time.
  • Ozymandias web interface provides access to the constructed knowledge graph.

Conclusions:

  • A biodiversity knowledge graph is feasible and valuable for integrating disparate data.
  • The developed methods facilitate the creation of shared knowledge spaces for biodiversity data.
  • The Ozymandias knowledge graph offers novel insights into Australian fauna research and publication trends.
