Study Guide, test 1 Flashcards
What is organismic biology?
Scientific discipline directed at the study of plant and animal diversity.
Ecology?
How animals live, function, reproduce, and interact with their environment.
What is evolutionary biology?
Systematic relationships among animal groups and the origins of diversity.
Biodiversity?
The degree of variation of life forms within a given species, ecosystem, biome, or planet.
What is mycology?
Scientists who study fungi are mycologists, study of fungi.
Botany?
Science involving the study of plants.
What is zoology?
The scientific study for animals
Species estimated to exist?
30-100 million
Known species?
5% of 30-100 million or roughly 1.9 million known.
How many extinction events have occurred?
Five mass extinctions have occurred since the Cambrian period. Biodiversity is being lost at a high rate thus we might be entering a sixth mass extinction.
What is anthropocene?
The Anthropocene is an informal geologic chronological term that serves to mark the evidence and extent of human activities that have had a significant global impact on the Earth’s ecosystems. It will include novel ecosystems and emerging disease under new environmental conditions.
What are ecosystem goods and services? Know examples. Whose/what provides them?
Species provide ecosystem goods and services and human society depends upon them. Plants provide water quality, carbon storage, and products whereas animals provide food, pollination, and seed dispersal.
What is the current biodiversity crisis?
It is caused by humans. It included accelerated rated of extinction in birds and mammals at 100-1000x greater than background rates. It also includes the anthropomocene period.
Why are species important?
Species provide ecosystem goods and services, organisms contain genetic information for all life processes on earth, and species have intrinsic value in human culture.
What is the scientific method? How does it work?
Hypothetico deductive method. Knowledge of phenomena leads to development of hypothesis leads to development of theory.
