What is a Conservation Biology Degree?

Conservation biology is a life science. Its mission is to protect and restore biodiversity – the diversity of plant and animal life on Earth.

To preserve biodiversity, conservation biologists and conservation scientists are focused on three questions: How is the diversity of life distributed around the planet? What threats does this diversity face? What can we do to reduce or eliminate these threats? These questions are at the heart of degree programs in conservation biology, which explore biodiversity at the genetic, species, and ecosystem levels.

Program Options

Bachelor’s Degree in Conservation Biology – Four Year Duration
Bachelor’s programs in conservation biology provide students with fundamental, foundational knowledge in the discipline. Courses address topics such as:

The components of biodiversity

  • All forms of life – bacteria, fungi, plants, insects and other invertebrates, and vertebrates
  • All levels of organization of living things – individual organisms and their genetic material; groups of similar organisms, such as populations and species; and groups of species in communities, ecosystems, and landscapes (groups of adjacent ecosystems)
  • All the interactions among the forms of life and their levels of organization, including competition, predation, and symbiosis

The biodiversity crisis

  • The rate of extinction has accelerated throughout human history.
  • The current rate of extinction is roughly 100 to 1,000 times greater than the natural rate.
  • This loss of biodiversity will harm people, because we depend on nature for food, medicines (such as cancer treatments), industrial products (such as oils and resins), and vital ecosystem services (such as water purification, erosion control, and climate control).

The value of biodiversity

  • Biodiversity benefits people directly and maintains interaction between the living and non-living parts of the environment. For example, biodiversity has provided plants for crops that feed billions of people, as well as decomposing organisms, such as bacteria and fungi, that release nutrients from organic material into soil and water.
  • Biodiversity has worth beyond the goods and services it provides humans and ecosystems. It has inherent value.

The three levels of biodiversity

  • Genetic diversity – refers to the range of different inherited traits within a species; in a species of high genetic diversity, there can be many individuals with a wide variety of different traits; for example, some individuals may look different while others may be more resistant to disease; genetic diversity is critical for individuals and populations to adapt to changing environments; the loss of genetic diversity makes a species more prone to extinction
  • Species diversity – different regions of the Earth have different types and numbers of species; all of the different types of species distributed around the globe contribute to the patterns of life on Earth
  • Ecosystem diversity – different regions of the Earth have different types and numbers of ecosystems; the diversity of ecosystems is important because different ecosystems have different properties; for example, wetlands purify water and forests take up carbon dioxide from the atmosphere, helping to control global warming

Ecosystems and their relevance to conservation biology

  • An ecosystem comprises living and non-living components that interact with one another, such as plants and animals with nutrients, water, air, and sunlight.
  • Ecosystems range in size from a few square feet to millions of square miles. There are no set ecosystem boundaries, rather they are defined by the particular component(s) that biologists are interested in. For example, a biologist who wants to know how residential development has affected the fish in a stream ecosystem might study the small streams that feed into a large stream as well as the surrounding land. Such an ecosystem would cover many square miles and would include hundreds of living and non-living components.
  • While conservation traditionally focused on protecting single species, the current focus is often on protecting entire ecosystems or even groups of ecosystems, known as landscapes. This trend increases the probability that we will protect large-scale processes, such as nutrient cycling, on which biodiversity depends.

Measuring biodiversity

  • Biologists measure biodiversity by first sampling the organisms and then extrapolating to estimate the total number of organisms.

Biodiversity hotspots and where they are concentrated

  • Biodiversity hotspots are areas that have large numbers of species and/or have many species that are not found anywhere else (endemic species).
  • Conservation efforts in hotspots can protect or restore a relatively large part of the total biodiversity worldwide.
  • Most biologists recognize about 25 global biodiversity hotspots that have many species as well as many endemic species. Most hotspots are in tropical regions, including the Amazon Basin, Central America, the Caribbean, Western Africa, Madagascar, Western India, and South East Asia. Many of these regions are hotspots because they have species-rich rainforests and coral reefs. However, there are also non-tropical biodiversity hotspots, including Central Chile, the Mediterranean Basin, South Africa, Eastern Europe, Central China, Western Australia, New Zealand, and the Pacific Coast of the United States. Other hotspots in the US include the southeastern region, California, and Hawaii.

The main threats to biodiversity

  • Habitat loss and fragmentation – result from development, clearing land for agriculture, water diversion, and logging
  • Habitat degradation – involves disturbing habitat features, such as extensive erosion or adding toxins to the soil or water; the most common causes of degradation are pollution and human recreation, such as off-road vehicles
  • Introduced species – species that people have intentionally or unintentionally moved beyond their native range; introduced species can devastate native species and ecosystems
  • Overharvesting – hunting, fishing, or collecting so many individuals from a species that it can no longer reproduce enough to withstand the harvest

Conserving biodiversity

  • Stop overharvesting species
  • Stop destroying habitats
  • Stop polluting and disturbing habitats
  • Stop spreading non-native species
  • Reverse damage that has already been done, by reintroducing native species and controlling invasive non-native species

Master’s Degree in Conservation Biology – Two Year Duration
The master’s program in conservation biology provides advanced training in the discipline to students who wish to enhance their career or prepare for doctoral studies.

Degrees Similar to Conservation Biology

Botany is the study of the physiology, structure, genetics, ecology, distribution, classification, and economic importance of plants. Degree programs in the field include courses in biochemistry, microbiology, photosynthesis, and plant evolution.

Students who pursue a degree in ecology study how organisms interact with the natural environments that they live in and how these environments can be protected. In other words, the focus of ecology is to understand ecosystems as well as the social and political interests and policies that threaten them. An ecology curriculum, therefore, starts with courses in both the natural sciences – like biology, chemistry, physics, and geology – and the social sciences.

Epidemiology, a fundamental science of public health, is concerned with health and disease at the population level; that is to say, within groups or communities. Its focus is the frequency, pattern, causes, and risk factors of diseases and other health-related events within these specified populations, which range from neighborhoods and schools to cities, states, countries, and the world at large.

Epidemiologists – often referred to as disease detectives – are the scientists and investigators whose work begins with looking for clues by asking questions. Who is sick? What are their symptoms? When did they get sick? Where could they have been exposed? Using statistical analysis, epidemiologists study answers to these questions and produce data that lead them to identify how a particular health problem was introduced, how its spread can be controlled, and how it can be prevented.

Fisheries Sciences and Management
Fisheries sciences and management degree programs focus on the biology and ecology of fish and shellfish. Students of the field learn about fisheries protection, production, and management. In short, the objective of these programs is to provide students with the knowledge and skills required to maintain long-term sustainable harvesting.

Forestry degree programs teach students how to conserve and manage forests through sustainable practices. This means the curriculum covers both preserving biodiversity, as well as producing wood products in ecologically responsible ways. Classes also address contemporary issues like climate change, carbon management, and how to plan and manage urban forests or green spaces in metropolitan areas.

Natural Resource Management
Natural resource management is about finding ways to sustain the Earth’s resources in the face of the growing human population. Majors in this discipline are typically passionate about clean water, clean energy, and clean environments. They study in the classroom, in the computer lab, and in the field and learn how to apply scientific and ecological knowledge, as well as economic and social awareness to find solutions to preserving our natural world.

Wildlife Science and Management
Wildlife science and management majors learn how animals exist within their habitats and ecosystems. Graduates in this field may become game wardens, conservation officers, natural resource officers, or wildlife managers.

Zoology students learn about animals, their evolution, anatomy, physiology, and natural habitats. Graduates may be employed by zoos, veterinary clinics, or labs. Their work may involve monitoring and writing reports on animal behavior, analyzing specimens to test for diseases, and/or working in the areas of ecology and conservation.
