08 - Dynamic Systems Flashcards
changing trend of a system over time
Dynamic Equilibrium
outside normal past/present habitat
alien species
Alien species that multiply quickly, out-compete, and change native habitats
Invasive Alien Species
International Treaty, 1992
develop strategies, identify/monitor components, legislation, protected areas systems
Convention of Biological Diversity (CBD)
positive feedback versus negative feedback
PF part of the ecosystem changes and affects same part while NF part of ecosystem counterbalances, reducing activity, and creating equilibrium
Polar Amplification
Example of positive feedback loop. The warmth makes snow-free area which makes warming
interaction that produces a greater effect than the effect of either one alone
Synergism
human intervention to renew a degraded/damaged/destroyed area
Ecological Restoration
negative Feedback Loop stays at an equilibrium while…
…Positive Feedback Loop pushes system conditions to change
maximum population ecosystem can support sustainably/indefinite period
carrying capacity
species reproduction ability regardless of what the environment can support
Biotic Potential
R-strategists VS K-strategists
R: species producing large numbers of young, little energy invested in upbringing
K: Species producing few offspring, considerable effort to ensure reach maturity
elimination of all individuals of a species from the present
extinction
study of the timing of recurring natural events in plants and animals. life cycle events of flora and fauna, and how influenced by climate and habitat
phenology
each generation of scientists sets baseline as current not from historical
shifting baselines
