Name: Score:61 Multiple choice questions
Definition
- Instead of increasing resistance to change, or supporting the resilience of the biotic community
to adapt to change, managers work to hasten and smooth the transition of the current biotic
community into one that aligns with future climate scenarios.
- Relocation of animal species and the seeding of desirable plant and tree species, often as part
of restoration efforts.
Metapopulation (Mainland-Island) (Source-Sink)
Which of the following is not an ecosystem management strategy in response to climate
change:
Managing Climate Change: Strategies for promoting increased resistance to ecosystem
change
Managing Climate Change: Strategies for promoting/facilitating the emergence of new
ecosystems1 of 61
Definition
A population of organisms consisting of many local populations.
- Mainland-Island: Large "mainland" subpop immune to extinction. This "mainland" is able to
export colonists to small "island" subpopulations. Some "Subpopulations" are prone to extinction
- Source-Sink: The source area is very high quality habitat. Individuals from the source area
disperse to the poorer quality sink habitats. Individuals in the sink populations are under stress
and reproductive rates will not sustain the populations

Minimum viable population (mvp)
Silvicultural Principles2 of 61 Definition
- Intensiv e mana gement of landscapes
- Intensiv e removal of invasive species, alteration of grazing r egimes, or landscape mana gement
such as tree thinning , to prevent events such as pest outbr eaks which ma y trigger shifts to new
biotic communities.
- Direct contr ol of pests through chemical treatment . Population mana gement (food provision ,
culling, breeding) to bolster species not favored under new climate regimes.
- Reintroduction of popul ations that are declining or locally extinct from nearby regions

Definition
Smal lest number of individual s in a species or popul ation capable of persisting at a specific
statistical probability level for a predetermined amount of time.
- Used in conser vation to justify listing of species and design of mana gement plans.

Disturbance and r egener ation6 of 61 Definition
- Assessing the perio d of optimal conditions for a species
- Quantifying ho w much the perio d has shift ed due to climate change and thereby determining
whether the response of a species is sufficient .
- Climate change ma y lead to different shifts in phenol ogy within food chains.
- Long distance migr ants not only face a tempor al problem, but also the sp atial problem of being
thousands of km away from their breeding sit e during winter.
- Some p arts of the food chain use temper ature unr elated cues to time their annual cycles
(marine diatoms)
We expect natural selection to shape the pl asticity of these species in such a way that they shift
their phenol ogy in accordance with that of their environment

Silvicul tural System

Definition
A planned pr ogram of silvicultural actions designed to achieve specific s tand s tructur e
characteristics to meet site objectiv es during the whol e life of a stand.
Integrates specific har vesting, regener ation, and s tand tending metho ds to achieve a predict able
yield of bene fits from the s tand over time.
- Naming the sil vicultural system is usual ly based on
1) the metho d of regener ation and
2) the desir ed age structur e
