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

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.

Stereotype Content Model02:16

Stereotype Content Model

15.4K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

The Bohr Model02:18

The Bohr Model

80.5K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

Summary

Mapping biodiversity hotspots requires comprehensive data. This study introduces a spatial model integrating phylogenetic data to identify key conservation areas and guide future biological sampling in data-deficient regions.

Area of Science:

  • Biodiversity conservation science
  • Spatial modeling
  • Conservation planning

Background:

  • Traditional biodiversity mapping relies on complete geographic distribution data, often unavailable.
  • Significant knowledge gaps in biological sampling exist, particularly in tropical, mega-diverse regions.
  • Using limited taxonomic groups or environmental surrogates is insufficient for accurate biodiversity modeling in countries like Brazil.

Purpose of the Study:

  • To develop a comprehensive spatial model for mapping high-biodiversity conservation areas.
  • To integrate multiple dimensions of biodiversity, including phylogenetic information, into conservation planning.
  • To identify priority areas for future biological sampling, especially in regions with knowledge shortfalls.

Main Methods:

  • Developed a comprehensive spatial model incorporating phylogenetic information and multiple biodiversity dimensions.
  • Utilized a genetic algorithm to identify minimal regions containing maximum species, phylogenetic diversity, endemicity, and phylogenetic endemism.
  • Applied the model to pinpoint critical areas for conservation and guide sampling efforts.

Main Results:

  • The model successfully identified small, highly biodiverse areas.
  • It also pinpointed regions with significant knowledge shortfalls, indicating where further sampling is crucial.
  • Results highlight the importance of considering multiple taxonomic groups and biodiversity dimensions.

Conclusions:

  • Conservation strategies must integrate multiple dimensions of biodiversity, including phylogenetic aspects.
  • Addressing sampling uncertainties and knowledge shortfalls is essential for effective conservation planning.
  • The developed model provides a robust tool for identifying priority areas in data-limited, biodiverse regions.
