bet36体育在线真的吗Take an expedition with us to investigate the amazing diversity of life on this planet.

bet36体育在线真的吗Healthy ecosystems require a large, diverse group of organisms, each doing their part.

bet36体育在线真的吗Healthy ecosystems provide crucial direct, indirect, and aesthetic-ethical benefits to humans.

bet36体育在线真的吗Areas that have a high diversity of unique and threatened species are known as biodiversity hotspots.

California's endemic plant species support a rich, diverse group of native and visiting organisms.

The storied Galápagos Islands are a heavily studied biodiversity hotspot that require our protection.

Human activities threaten the endemic plant and animal species of the Gaoligongshan region of China.

Madagascar's geologic history set the stage for the evolution of the island's unique flora and fauna.

bet36体育在线真的吗How does Central America’s mountainous spine contribute to the rich biodiversity in the region?

bet36体育在线真的吗The Philippines is home to one of the most diverse assemblages of species in the world.

bet36体育在线真的吗São Tomé and Príncipe may be home to more endemic bird species than anywhere else on Earth.

bet36体育在线真的吗Where do we find biodiversity? Life is everywhere on Earth, but it is not distributed evenly.

Several factors, such as climate and geography, determine the preferred habitats of various organisms.

When and how did biodiversity studies begin, and how have they changed over time?

What types of equipment and logistical support do scientists need in the field to study biodiversity?

Collecting specimens in the field launches the lab work of analysis, documentation, and cataloging.

Scientists estimate that we have documented only about 10 percent of the Earth's biodiversity.

bet36体育在线真的吗Human activities and population growth threaten biodiversity in almost every corner of our planet.

How do introduced species cause problems for biodiversity and what makes a species invasive?

As human activities warm the Earth, biodiversity levels and distributions are changing at alarming rates.

bet36体育在线真的吗Why are the oceans becoming more acidic and how does that threaten biodiversity?

Our greatest tool for stemming the loss of biodiversity is the symbiosis between science and education.

Efforts to slow extinction rates focus both on species themselves and the preservation of their habitats.

Advocates for biodiversity conservation come in all forms, from single individuals to international agencies.

See how local policies can grow into global efforts to protect life on Earth.

How does natural selection give rise to new species?

bet36体育在线真的吗What is the connection between genes and biodiversity?

When organisms reach new habitats or become isolated, the stage is set for new species to evolve.

Over time, species richness has undergone significant ups and downs.

bet36体育在线真的吗How does genetic diversity within populations contribute to species survival?

bet36体育在线真的吗Explore why understanding ecosystem diversity is critical to making sound conservation decisions.

Discover how evolutionary lineages are linked through a shared history and depicted in the tree of life.

Examining the details of the tree of life provides important lessons for conservation efforts.
