What is Biodiversity?01:19

What is Biodiversity?

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 Biodiversity01:50

Threats to Biodiversity

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 Values01:24

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.
What is Conservation Biology?01:57

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.
Conservation of Small Populations02:04

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...
Conservation of Declining Populations02:07

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

This summary is machine-generated.

Livestock breeds can be invasive, impacting biodiversity and local breeds. Policy changes are needed to conserve animal genetic resources and balance food security with biodiversity protection.

Area of Science:

  • Agricultural Science
  • Conservation Biology
  • Genetics

Background:

  • Livestock species, integral to global food production, present a complex case for invasiveness due to their human-managed nature.
  • The simple negative connotation of invasive species is challenged by the widespread distribution of domesticated animals.
  • Livestock production poses a significant threat to natural biodiversity.

Purpose of the Study:

  • To analyze the institutional context of livestock invasiveness concerning genetic diversity.
  • To discuss the impacts of livestock on natural and agricultural biodiversity, including breed and within-breed diversity.
  • To propose measures for controlling genetic erosion and managing policy trade-offs.

Main Methods:

  • Conceptual analysis of invasiveness in the context of agricultural and natural biodiversity.
  • Review of factors influencing breed selection and market dynamics.
  • Examination of policy objectives related to biodiversity, genetic resources, and food security.

Main Results:

  • A few domesticated species, due to their global spread for food production, complicate the definition of invasive species.
  • Market dynamics and policy distortions favor high-output international breeds over local breeds, increasing their economic 'invasiveness'.
  • Livestock production continues to negatively impact natural biodiversity.

Conclusions:

  • Countries must balance conservation of animal genetic resources and food security with controlling invasive alien species.
  • Policy interventions are crucial to mitigate genetic erosion caused by uncontrolled gene flow and market pressures.
  • Sustainable management is required to address the complex interplay between livestock, biodiversity, and agricultural systems.
