1
Q

All landscapes have what? (single word answer)

A

History

  • Legacies in terms of space and time
  • Pattern and process = connection
  • Why do landscapes look the way they do
2
Q

What is the ‘right’ scale for all landscape ecology studies?

A

No single right scale

  • Depends on question being asked and the processes of interest
  • Deer study guest lecture
3
Q

What is available/can be used to quantify landscape pattern?

A
  • Many metrics are available
4
Q

Landscape pattern includes both of what (2 words)?

A
  • Composition and Configuration

- ie. is it homogeneous, what is the arrangement

5
Q

Landscape structure does not equate to landscape function, T or F?

A

True

6
Q

Disturbances have what interaction with landscape heterogeneity?

A

Disturbances create and respond to landscape heterogeneity

7
Q

What is an example of how disturbances create and respond to landscape heterogeneity that is not the MPB?

A

Fire

  • Intensity varies based on topography heterogeneity such as where it might be wetter
  • Intensity and severity of fire create different patches of heterogeneity over landscape, recovery will also vary
8
Q

Characteristics of the surrounding landscape (matrix) can affect local populations, T or F?

A
  • True

- Ex. Song birds and fence posts surrounded by field

9
Q

Cascading effects and an example

A

Species interactions produce feedbacks that influence landscape pattern and process
- Wolves and elk in Yellowstone

10
Q

Landscape elements can serve as what?

A
  • Sources or Sinks for Abiotic and Biotic components
  • Burned areas are sources of nutrifying for some species while they can also be a sink due to the burned habitat that is lost
11
Q

Human influences are dominant factors that control ecological dynamics at what scales?

A
  • Broad scales

- Growing area of research, urban planning

12
Q

Maintaining ecologically functional landscapes is critical for sustaining what?

A
  • Human well-being

- Watershed and water security due to forest landscape around water source, the forest must be functioning

13
Q

What are the 8 main future directions in landscape ecology?

A
  • Relating landscape metrics to ecological processes
  • Thresholds, nonlinearities, and rules for scaling
  • Causes and consequences for land use change
  • Sampling
  • Interactions among multiple drivers
  • Climate change
  • Changing disturbance regimes (and with climate change)
  • Behavioural landscape ecology (How animals use landscape, guest lecture)
14
Q

Nonlinearities

A

Tree rings:
- increase in width w/ warm temps but at some point the temp is too warm and rings will actually decrease in width in response to climate
