Rough-Skinned Newts and Ecosystem Impact

The video explores the hidden life within a backcountry pond, focusing on the rough-skinned newts. Biologists capture a salamander and discuss the importance of amphibians. The rough-skinned newts, protected under the BC Wildlife Act, are studied for their population and the presence of a harmful fungus. The video highlights the newts' toxicity, their ecological role, and the threats they face from habitat degradation and invasive bullfrogs.

What is the primary focus of the biologists' excitement in the introduction?

• The sighting of a rare fish

• The capture of a type of salamander

• The discovery of a new plant species

• The capture of a rare bird

During which season do rough-skinned newts migrate for breeding?

• Spring

• Autumn

• Winter

• Summer

What significant discovery was made about the rough-skinned newts in Morel Lake?

• They are immune to all diseases

• They carry a fungus affecting amphibians

• They have a unique diet

• They are the largest amphibians in the area

What makes rough-skinned newts poisonous to most predators?

• Their speed

• Tetrodotoxin in their skin

• Their size

• Their bright colors

What is the significance of the orange belly in rough-skinned newts?

• It attracts mates

• It helps in thermoregulation

• It helps them blend with the environment

• It is a warning signal to predators

Why is the ecological importance of ponds emphasized in the video?

• They are easy to maintain

• They are used for recreational activities

• They support a diverse range of species

• They are a source of drinking water

What could be a potential consequence of losing all newts on the island?

• More recreational space

• Improved water quality

• Cascading effects through marsh ecosystems

• Increase in fish population

What is the primary concern regarding the degradation of ecosystems?

• Decrease in water levels

• Loss of biodiversity

• Loss of recreational areas

• Increase in tourism

What is the new threat to the rough-skinned newt population?

• Climate change

• American bullfrogs

• Deforestation

• Increased pollution

How do American bullfrogs affect the marsh environments?

• They help in plant pollination

• They prey on newts and other creatures

• They reduce algae growth

• They improve water quality
