Ecosystems Flashcards
(30 cards)
a physical system composed of a set of biotic and abiotic elements that are interdependent
ecosystem
a period rapid change
phase transition
non-addictive interactions and feedback loops over time can give exponential relations between input and output
nonlinearity
appear as networks in a higher level
connectivity
enables self-organization & the process of evolution that shapes complex systems
autonomy (& adaptation)
terrestrial ecosystem: arid
deserts
terrestrial ecosystem: lush vegetation, high faunal diversity
tropical rainforest
terrestrial ecosystem: cold, short growing season
tundra
terrestrial ecosystem:rainfall low but higher than in deserts
grassland
terrestrial ecosystem:leaves fall in autumn (four seasons are more pronounced)
temperate deciduous forests
aquatic ecosystems:standing water
lentic
aquatic ecosystems: running water
running water
aquatic ecosystems: high diversity
coral reefs
aquatic ecosystems: salinity tolerant trees
mangroves
aquatic ecosystems:stabilize sediment, improve water clarity
seagrass meadows
aquatic ecosystems: low light conditions
deep sea
increases system complexity
heterogeneity
increase a system’s resilience and robustness
degree of complexity
measure of population demographics in a certain geographical area
spatial complexity
a measure of species richness;snapshot of a population at a given time
heat map
used to characterized time series of different variables system dynamics
temporal complexity
describes not only relationships but also the organization between components of a system
structural complexity
highly ordered w/ each node having exactly the same number of links
planar networks
connections are created at random based on a certain probability of connectivity
random networks
