AP Biology Unit 2 Progress Check

Population Changes Due to Industrialization

• Dark-colored moths increased in percentage as a result of industrialization, while light-colored moths decreased.

Ecosystem Services

• Regulating services include pollination, decomposition, and water purification.

Biomass Post-Disturbance

• Sweetgum experienced the greatest biomass during a specific post-disturbance year (year not specified).

Ecosystem C Characteristics

• Low species diversity in Ecosystem C suggests species with low population sizes; high genetic diversity indicates quick evolution potential.

Author's Claims on Gharials

• The 2008 gharial die-off was linked to anthropogenic disruptions, affecting already threatened species.

Economic Consequences of Global Warming

• Increased global warming may lead to the collapse of local fisheries due to coral reefs' damage from ocean acidification.

Ecosystem Recovery Rates

• Ecosystem B is likely to recover fastest from natural disruptions.

Finch Population Analysis

• Finch populations benefited in 1977 due to a food abundance, while increased beak size in 1980 helped them survive a drought.

Tree Species in Succession Stages

• Sweetgum is predicted to be the predominant species found during the intermediate succession stage.

Atmospheric CO2 and Antarctic Temperature

• Over the past 800,000 years, atmospheric CO2 concentration and Antarctic temperature are directly correlated.

Temperature Changes Over Time

• Between 440,000 and 340,000 years ago, Antarctic temperature showed an increase of about 12°C followed by a decrease of about 12°C.

Claims on Reef Fish and Coral

• Climate change negatively affects coral reefs, impacting reef fish survival.

Island Biogeography

• The island 30 hectares in size that is 10 kilometers from the mainland would likely host the highest number of species.

Population Bottlenecks in Ecosystems

• Ecosystem A likely experienced a bottleneck due to low genetic diversity, indicating a reduced gene pool variation.

Effects of Invasive Generalist Species

• Introduction of an invasive generalist will decrease the population size of island's specialist species due to increased competition for resources.

Acidic Water Impact on Salmon

• Acidic water interferes with salmon's sensory capabilities, affecting their predator detection ability.

Hurricane Protection Ecosystem Services

• Intact coastal wetlands provide significant protection from hurricane storm surges, contrasting with managed systems like locks and dams.

Species Richness Post-Disturbance

• The year with the greatest species richness post-disturbance is identified, highlighting ecological recovery dynamics.

Invasive Species Survival Predictions

• Native species on Madagascar are more likely to survive invasions compared to those on Easter Island due to larger habitat diversity.

CO2 Concentration Trends

• CO2 concentration fluctuated historically but rose exponentially recently, indicating significant climate change implications.
