Self-controlling feedback system
|
A system that is composed of groups of interrelated parts that function to produce an equilibrium.
Feedback loop mechanism = close loop system |
|
What are the four components of a feedback system
|
1) Source of energy
2) Means of transferring energy into a usable form 3) System must have ability to vary with conditions (cannot be static) 4) System must have inherit limitations in efficiency. If too efficient, it will break down |
|
What are two problems of "equilibrium in ecology"
|
1) No system is in constant and perfect equilibrium
2) Function of a system does not create stability (balance between competition and cooperation) |
|
What are the abiotic components of an ecosystem
|
Elements: C,H,O,N,P,K
Solar energy |
|
What is a biome? What are the five components of a biome?
|
Biome = combined relationship between abiotic and biotic elements
Main components: MALTA 1) Moisture 2) Altitude 3) Light 4) Temperature 5) Atmosphere |
|
What are the three classes of biotic elements?
|
Producers- plants take abiotic elements and produce biotic elements
Consumers- obtain all energy from producers Decomposers- feed of the dead organic material and convert biotic elements to abiotic (simple) organic material |
|
What is a trophic system? What are the different components of a trophic system?
|
Trophic system- transfer of energy through an ecosystem
Autotrophic level- plants use solar energy to convert inorganic chemicals into organic chemicals. This is the first level of a trophic system. Competition for abiotic components determines the form of a plant Hetertrophic level- get energy directly from biotic elements 1) Herbivores: These are primary consumers. Ex = colobinae 2) Carnivores: These are secondary consumers. Eat animals that eat plants. Ex = tarsiers 3) Decomposers |
|
What are some of the evolutionary adaptations that have been made by herbivores to aid in plant digestion?
|
1) Many molars
2) Enlarged cecum 3) Multisached stomachs |

|
How much energy is lost in transfer between consumer levels
|
About 90% is lost. That is, only 10% is transferred to the next energy level
|
|
What is the process of succession?
|
An orderly change in the environment from one community to another until a stable equilibrium is attained at that area
|
|
What is a climax community? What are characteristics of a climax community?
|
Climax Community: a community where no other species is able to out-compete that of a native species. This is an example of a dynamic equilibrium
Characteristics 1) Germination rates = death rates 2) Plants share similar structural features |
|
What is a disclimax?
|
Overuse of the environment which prevents a climax community from ever being reached
|
|
What is the optimum environment for a seedling?
|
The optimum environment is the environment that came before that environment developed
|
|
What is primary succession? What happens during primary succession?
|
Normalization of the environment by pioneer plants and abiotic elements. This creates near optimal conditions for vascular plants. Formation of soil occurs during this period
|
|
Desert

|
Neutralism
|
(0,0). Neither population is affected by the presence of another
|
|
Competition
|
(-,-). Each population adversely affects the other in struggle for food, nutrients and space
|
|
Mutualism
|
(+,+). Growth and survival of both populations are benefited by presence of another. Neither could survive without the presence of another. Ex. gut flora
|
|
Protocooperation
|
(+,+). When both populations benefit from presence of each other, but relationship is not obligatory. Ex. Flowers and insects
|
|
Commensalism
|
(0,+) One population benefits and the other is not affected
|
|
Amensalism
|
(0,-) One population is inhibted and the other is not affected (ex. Penicillin)
|
|
Parasitism (+,-)
|
One population adversely affects the other by direct attack
|
|
Predation (+,-)
|
One population, the predator, kills and consumes the other population, the prey
|
|
Liebrig's Law of the Minimum
|
States that the material
(including chemical, water, heat, energy, space) that is most limited in supply will be the limiting factor for the population. I.e. An organism is no stronger than its weakest link in an ecological system. this will affect the distribution of populations |
|
Carrying Capacity
|
The maximum size of a population that an environment can hold
|
|
Keystone species
|
Species of food that the animal needs in order to maintain its current carrying capacity
|
|
Joseph Bridsell
|
Found that Aborigine population distribution is related to rainfall
|
|
Shelford's Law of Tolerance
|
States that too much of a material can be a limiting factor
Any condition that exceeds the limits of tolerance is a limiting factor |
|
Stenothernal
|
When a species has small tolerance to temperature variations. Relates to Shelford's Law of Tolerance
|
|
Eurythermal
|
When a species has wide tolerance of temperature variations
|
|
George Schaller
|
Person who showed that predators often become extinct before prey species
|
|
What are the three ways that prey species defend themselves?
|
1) Try to exploit the limits of a predators motor or sensory capacity
• Can be dispersal • Camouflage- can be active or passive 2) Exploitation of the predators learning ability • Imitate other species that are toxic- constant coevolution • Displays- many primates have large canines 3) Direct Protection • Horns, scales, spines and canines • Loris- vertebrae are sharp and butts predator • 3:1 weight ratio between predator and prey- above this ratio, will not fight back |
|
Cooperative Polyandrous Group (Communal Breeding)
|
Social group in which a group of multiple males and females interact with each other. However, only one female is reproductively active
Primates: Callitrichidae (tamarinds and marmosets) |
|
Multi-Male Group
|
Groups consist of more than one adult male and more than one adult female and offspring.
Some variation in how many females there are Most common type of nonhuman primate social group Primates: Cebidae (capuchins, squirrel monkeys), savanna baboons, diurnal lemurs, Colobinae, gorillas |
|
Allochronic species
|
Two groups of animals living in the same lineage, but during different time periods
|
|
Cohesion concept of species
|
Species are groups of animals that share a suite of genetic, phenotypic, demographic, ecological, and behavioral characteristics or cohesive mechanisms that help maintain the group as a cohesive unit
|
|
Monotypic
|
When there is only once component of a group (ex. only one species of Homo)
|
|

Describe Lemuriformes. Where are they found? When are they active? What familes are part of this suborder?
|
Lemuriformes are found in costal regions of Madagascar. They are small animals that are active during the night (nocturnal) or day (diurnal). They are frequently referred to as “secondary nocturnal” because all ancestors are diurnal. There are five families of lemuriformes, including Cheirogaleidae, Lemuridae, Lepilemuridae, Indriidae, and Daubentoniidae.
