23
Q

K strategy

A

Reproductive strategy where a small number of offspring are produced with a high energy input

24
Q

Kinesis

A

A non-directional response where the rate of movement or activity is influenced by the external or environmental stimulus

25
Klinokinesis
The change in the rate of turning of an organism, where the rate is faster in unfavorable conditions
26
Lek
The area where animals come together and perform mating displays to attract mates for breeding
27
Long day plants
Plants that flower in the summer when the day length exceeds a critical length
28
Migration
Regular movement of whole populations to a specific location
29
Mimicry
Where one species resembles another in some way
30
Monogamy
Having one mate for a breeding season
31
Mullerian Mimicry
A form of mimicry where two unpalatable species resemble each other
32
Mutualism
An interspecific relationship where both species benefit
33
Nastic-response
Non-directional growth response in plants to the intensity of an external/environmental stimulus
34
Navigation
The ability of an organism to use landmarks or natural compasses to find its way home
35
Orthokinesis
Change of speed of an animals movement, where the movement is faster in unfavorable conditions
36
Parasitism
Exploitation involving a typically smaller species(parasite) living on or in a larger species (the host) where it steals the host's resources
37
Phase-shift
The change in the start time of activity or inactivity as a result of entrainment
38
Photoperiodism
The regulation of seasonal activities of plants by the day length, or photoperiod
39
Phytochrome
A type of plant pigment which has 2 forms, Pr and Pf and controls the flowering of plants
40
Polygyny
Where a male has multiple female mates
41
Predation
Exploitation involving an animal hunting and feeding on another
42
R strategy
The reproductive strategy where a large number of offspring are produced with a low energy input
43
Short-day plants
Plants which flower in the winter when the day length is less than a critical length
44
Taxis
A directional response involving the movement of an animal towards or away from a directional external stimulus
45
Territory
The defended area where an animal lives
46
Tropism
A growth directional response in plants to a directional external stimulus
47
Zeitgebers
Environmental stimuli which reset the internal biological clock
48
Why is it important for plants to flower at certain times?
Reproduction. Flowering needs to occur when insects are most active because the flowers are pollinated by insects to increase their chances of survival
49
Things that might control exogenous rhythm?
Light availability, tide length, changing in day length
50
What are circadian rhythms triggered by?
Light availability
51
What are circannual rhythms triggered by?
Changes in day length(due to changes in season)
52
What are circatidal rhythms triggered by?
Changes in tides(due to gravity and earth's rotation)
53
Importance of tropism
Keep plants alive, plants grow towards the good stuff and away from the bad stuff
54
Stimuli involved in tropism and nastic responses
Light, Gravity, Chemicals, Touch, Water, Temperature
55
Ways of navigation
1. Using landmarks 2. Solar navigation 3. Magnetic field line navigation 4. Star navigation
56
Why animals migrate
1. So that the population can move to a more favorable location with a more favorable climate and habitat. 2. Usual home has run out of food, move to new feeding ground
