Ecological Succession and Biodiversity Intro

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species, genetic diversity, and the variety of ecosystems.

What is a biodiversity crisis?

Back

A biodiversity crisis is a significant decline in the variety and abundance of species in an ecosystem, often indicated by high rates of extinction.

What are plethodontid salamanders?

Back

Plethodontid salamanders are a family of lungless salamanders that breathe through their skin and are often found in moist environments.

How does biodiversity affect ecosystem sustainability?

Back

Higher biodiversity generally enhances ecosystem sustainability by providing resilience against environmental changes and supporting various ecological functions.

Front

What is the Phanerozoic eon?

Back

The Phanerozoic eon is the current geological eon, beginning around 541 million years ago, characterized by abundant fossil evidence and significant evolutionary developments.

Front

What is the significance of protected areas for biodiversity?

Back

Protected areas are designated regions aimed at conserving biodiversity and ecosystems, often showing higher sustainability and lower extinction rates.

Front

What is adaptation in ecology?

Back

Adaptation is the process by which a species becomes better suited to its environment through evolutionary changes in traits.

Front

What is the difference between land-based and marine biodiversity?

Back

Land-based biodiversity refers to the variety of life found on land, while marine biodiversity pertains to the variety of life found in oceanic environments.

Front

What is the role of non-native species in ecosystems?

Back

Non-native species can disrupt local ecosystems, often outcompeting native species and leading to declines in biodiversity.
