Biodiversity and Environmental Indicators

The video tutorial covers the definition and measurement of biodiversity, emphasizing the importance of a species database for restoration projects in Gorongosa. It highlights the role of technology in conducting biodiversity surveys and discusses the significance of indicator species, such as bats, in assessing ecosystem health. The tutorial also explains how macroinvertebrates can be used to evaluate water quality in streams.

What is biodiversity often approximated as?

• The number of habitats

• The number of species

• The number of ecosystems

• The number of continents

Why is building a species database useful for restoration projects?

• To increase tourism

• To track climate change

• To understand species diversity

• To improve park facilities

Why do researchers need to conduct biodiversity surveys in different locations?

• To find new tourist spots

• To increase funding

• To compare species diversity

• To build more databases

Which technology is NOT mentioned as helpful in biodiversity surveys?

• Drones

• GPS

• Satellite maps

• Virtual reality

What is an indicator species?

• A species that is extinct

• A species that is rare

• A species that reflects environmental conditions

• A species that is always abundant

How can bats indicate the health of an ecosystem?

• By their size

• By their color

• By their abundance

• By their speed

What are macroinvertebrates?

• Microscopic organisms

• Invertebrates visible without magnification

• Small fish

• Large mammals

What does the presence of pollution-intolerant species in a stream indicate?

• The stream is overcrowded

• The stream is dry

• The stream is healthy

• The stream is polluted

How is relative water quality determined between two streams?

• By comparing species diversity

• By comparing their temperatures

• By comparing their flow rates

• By comparing their depths

What is the formula for calculating percent increase?

• Ending value minus starting value

• Starting value divided by ending value

• Ending value minus starting value divided by starting value times 100

• Starting value minus ending value divided by ending value times 100
