Threats to Biodiversity01:50

Threats to Biodiversity

27.1K
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...

What is Biodiversity?01:19

What is Biodiversity?

33.7K
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.

Biodiversity and Human Values

17.1K
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.

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,...

Global Climate Change01:50

Global Climate Change

28.9K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Area of Science:

  • Ecology
  • Evolutionary Biology
  • Landscape Ecology

Background:

  • Biodiversity patterns are influenced by landscape structure and organism dispersal.
  • Landscapes and dispersal strategies are dynamic and co-evolve.
  • The interplay between geomorphological changes and dispersal evolution on biodiversity remains unclear.

Purpose of the Study:

  • To investigate how evolving dispersal strategies interact with landscape structure to shape biodiversity patterns.
  • To model these dynamics in river networks simulating geomorphological changes.
  • To understand the combined effects on biodiversity in changing environments.

Main Methods:

  • Development of metacommunity models incorporating dispersal evolution.
  • Implementation of models in river networks with varying structures.
  • Simulation of geomorphological dynamics within fluvial landscapes.

Main Results:

  • Compact river networks promote a more well-mixed environment for a fixed dispersal strategy.
  • Dispersal evolution leads to more localized strategies in compact networks, counteracting mixing effects.
  • The interplay of evolving dispersal and landscape structure generates unique biodiversity patterns.

Conclusions:

  • Biodiversity patterns are significantly altered when dispersal evolution is considered alongside landscape dynamics.
  • Understanding the co-evolution of dispersal and landscape is crucial for biodiversity management.
  • Future studies must integrate these interacting factors to accurately predict biodiversity in changing environments.
