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.
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.
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...
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.

Area of Science:

  • Ecology
  • Conservation Biology

Background:

  • Ecological complexity and contingency hinder the development of general predictive rules in ecology.
  • Conservation biology requires a robust conceptual framework to guide effective management practices.

Purpose of the Study:

  • To present a set of fundamental concepts for conservation biology.
  • To stimulate constructive debate and further develop the discipline's theoretical underpinnings.

Main Methods:

  • Conceptual synthesis of key ideas in conservation biology.
  • Proposal of ten core principles for successful conservation management.
  • Establishment of an online platform for continued discussion and concept development.

Main Results:

  • Ten core concepts for conservation management are outlined, including explicit goals, biodiversity maintenance over species richness, holistic approaches, diverse management strategies, utilizing nature's template, focusing on causes, acknowledging uniqueness, understanding threshold responses, addressing multiple stressors, and recognizing the influence of human values.
  • The proposed concepts aim to enhance the efficacy and efficiency of conservation actions.
  • A framework for ongoing scientific discourse on conservation biology principles has been initiated.

Conclusions:

  • The presented concepts offer a foundational understanding for conservation biology.
  • Continuous dialogue and refinement of these concepts are crucial for the maturation of conservation biology as a discipline.
  • An online forum is established to foster collaborative development of conservation principles.
