Galls and Stream Ecosystem Assessment

The video tutorial from Kentucky State University covers the ecological study of Golden Rod and its associated galls, focusing on the collection and analysis of these galls to understand insect interactions. It also includes a study of macroinvertebrates in streams to assess pollution levels. The tutorial provides practical instructions for fieldwork, safety tips, and guidance on writing a scientific paper based on the collected data.

What is the primary role of the Golden Rod Gall fly in the ecosystem?

• Feeding on leaves

• Producing honey

• Pollinating flowers

• Forming galls on Golden Rod

Which creatures are known to feed on the Golden Rod Gall?

• Birds and mammals

• Ants and spiders

• Butterflies and bees

• Paracoid wasps and beetles

What is a key safety precaution when collecting Galls?

• Wearing a mask to avoid pollen

• Using a net to catch insects

• Wearing gloves to avoid cuts

• Using a magnifying glass

What tool is used to measure the diameter of Galls in the lab?

• Ruler

• Calipers

• Microscope

• Scale

What is the purpose of identifying the insect species in the Galls?

• To write a scientific paper

• To assess the health of the ecosystem

• To enhance the plant's growth

• To determine the age of the plant

Why is it important to compare macroinvertebrates in different streams?

• To measure water temperature

• To identify new species

• To assess pollution levels

• To find the cleanest water source

What indicates a low pollution level in a stream?

• High fish population

• Clear water

• Presence of algae

• High diversity of macroinvertebrates

What should be worn to protect against blackberries during fieldwork?

• Hats

• Sandals

• Pants and long sleeves

• Shorts and t-shirts

What is the final step in the fieldwork process?

• Collecting water samples

• Releasing captured insects

• Combining collected items into one bag

• Measuring water temperature

What is the main focus of the final instructions given in the video?

• Scheduling the next field trip

• Cleaning the equipment

• Preparing for a presentation

• Ensuring all data is collected and organized
