- Biodiversity
- Endemic Species
- Biodiversity hotspots
- Species Richness
- relative species abundance (evenness)
- 3 terms of measuring biodiversity over spatial scales.
- Alpha Diversity
- Beta Diversity
- Gamma Diversity
- Alpha Diversity
- Beta Diversity 1 / 2
–Answer the variety of life in the world or in a particular habitat or ecosystem.
–Answer Species native to one place. Richness of diversity in tropics also mean knowledge of species is lowest and high potential for biodiversity loss.
–Answer High number of endemic species. Identifying important locations on planet for conservation efforts. Protects hotspots to protect large # of species.
–Answer Number of species present in an area.
–Answer the number of individuals present for each species in an ecosystem. Primary producers typically have the highest relative abundance.
–Answer
–Answer Diversity within particular area/ecosystem. Expressed by # of species in that ecosystem.
SUBSCRIBE
–Answer Measurement that examines the change in species diversity between these ecosystems.-Counting the total # of species that are unique to each of the ecosystems being compared.
- Gamma Diversity
- Genetic Diversity
- Ecological Disturbances
- Primary Succession
- Secondary Succession
- Pioneers/Early successional species
- intermediate disturbance hypothesis
- / 2
–Answer Measures overall diversity for different ecosystems within a region.
–Answer Raw materials for adaptations in species.
–Answer Changes in community structures & composition over time induced by volcanos, earthquakes, storms, fires, etc.-Normal communities unaffected and @ equilibrium.
–Answer Newly exposed or newly formed land is colonized by living things.
–Answer Part of ecosystem is defined and remnants of previous community remains.-Succession in response to enviornmental disturbances moves a community away from its equilibrium
–Answer Species that're well adapted for exploit- ing disturbances
–Answer Local species diversity is maximized when ecological disturbances are neither too rare nor too frequent.
