Q

What is ideal free distribution?

A

One area/patch might be ideal, but if everyone decides to go there then there will be too much competition, which means that they will have to disperse anyways.

Q

Are animals able to socially learn?

A

Yes, one good example of this is the milk birds (tits), they would drink milk off of peoples poarches and this was taught by another bird. Along with this we have orcas teaching each other how to sink boats.
- Humpback feeding strategy (blow bubbles to confuse fish) and the lobtail method

Q

Overall is social learning adaptive? (what are some maladaptive features vs. adaptive)

A

Maladaptive:
- traditions may persist after conditions have changed
- Traditions started by a single event might lead to suboptimal behavior
- Message may get corrupted

Adaptive:
- very fast spread of new ideas/discoveries
- Safer as only one animal needs to investigate new dangers
- Identity of predators, good food etc. can be passed on to young safely

25
What do you need to have effective social learning?
1. a big brain 2. educated demonstrator 3. living demonstrator 4. Social bond w/ demonstrator
26
What are the types of cultural transmission?
Vertical: learning from parents (bird song) Horizontal: learning from peers, i.e. members of your own age group (dolphins) Oblique: learning from adults other than your parents (found in complex social groups; humans are one)
27
What are the outcomes from social learning?
1) spread new ideas very quickly 2) Local dialects and traditions (culture?) 3) Speciation can result
28
What are the 5 mechanisms of social learning often mistaken for true imitation?
1. Instrumental learning 2. Stimulus enhancement 3. Social facilitation 4. Contagion 5. Emulation
29
What can lead us to believe that something is social learning when it is not?
Poor experimentation designs can get to the wrong conclusions about experimental learning. A lot of the time it is confused with imitation.
30
What is Stimulus enhancement?
learning by watching others, that a particular object or area is of interest (Blue tits)
31
What is Social facilitation?
Carrying of an already known behavior when others in a social group are doing it too. Advantageous bc its safer
32
What is Contagion of observation?
Conditioning --> catches mood of demonstrator and then copies its general attitude
33
What is Emulation?
When an animal learns a new behavior or sequence of movements which lead to a particular goal, watching the demonstrator carry out the sequence of events. (Humans use this a lot)
34
What is the definition of teaching?
when the demonstrator modifies its behavior only in the presence of appropriate naive observer with some cost to itself.
35
What is one example of culture? in the animal kingdom:
Chimps in Africa have different colonies that do different things, like use different tools, have different calls etc.
36
Why don't animals respond the same way when put in the same situation?
1) Hormones, parasites, neurophysiology, diurnal cycles 2) Animals play different strategies 3) Different personalities
37
What are evolutionary stable strategies (ESS)?
Strategies which cannot be invaded by another strategy
38
What are two different strategies when fighting?
- Run a way (dove) - Attack (Hawk)
39
What is "war of attrition"?
How long you can hold out before running away.
40
What are different feeding behaviors (pigeons)?
There are producers and then there are scroungers.
41
What are ways that we can help extinction?
1. Stop thinking of insects as pests 2. plant things, vegetation 3. understand behavior and apply your understanding
42
What do you do in behavioral ecology?
1. Count populations - need to know how many endangered species you have 2. Dealing with small populations - small populations have different behaviors and growth rates than larger ones 3. Identifying and alleviating the affects of disturbance
43
What are the different ways we can count populations?
1. Total counts 2. Incomplete counts 3. Indirect counts 4. Capture-mark-recapture
44
What is a Total count?
Total counts: sometimes animals are out in the open and they can all be counted
45
What is an Incomplete count?
Incomplete counts: count part of the population, according to how much to how much population there is
46
What is an Indirect count?
count indicators of the animal (i.e. feces)
47
What is a Capture-mark-recapture?
capture as many as possible then release them and assume the population remixes (most used method)
48
Why are monogamous populations more prone to extinction?
1) Chance events make failure to breed more likely 2) females with poor quality mates don't invest very much into that years offspring
49
What is aggregation?
a cluster of individuals, living in a group
50
How does aggregation help survival?
- fertilization more likely - hunting/food discovery benefits - co-operation in predator defense - defense against environmental stress - genetic diversity
50
What is the allele effect?
group size reduction leads to extinction
51
What is an example of the allele effect?
An example of this would be the passenger pigeons, there was a massive flock that held 3.5 billion birds (1/4 of all north American birds). But they were massively over hunted, and there environment went away. They had a reduced mating probability, reduced parental investment, increased risk of predation, reduced protection from environmental stress
52
What are the effects of farming?
- Harvesting of populations needs a good grasp of all aspects of biology so that they can avoid collapse
53
What are the effects of hunting?
1. sex based hunting, killing a lot of males or a lot of females can hurt populations (grizzly bears) 2. Complex biases: only hunting bigger salmon which results in less and more jacks
54
What is an anthropological disturbance?
Light pollution, water turbidity, sound pollution
55
What is an example for anthropological disturbance having to do with light pollution?
Turtles have a really hard time when there is light pollution around mating season, as they follow light to go back to the water. So cities have become mindful and now do not have lights on or use a red light
56
What are issues of animals that are kept in captivity?
- Imprinting problems - Lack of recognition of threats - Lack of hunting skills - Movement problems - Stress and boredom - small population effects - personality selection
57
Why do we have zoo's ?
- last hope of survival for the species - to inform conservation - Education for the public: improves interest in the animal - Raises money for conservation - provides individuals for reintroduction
58
What are drawbacks of zoos?
- Difficult to prepare species for reintroduction - Gene pool restricted - species specific behaviors - very few, charismatic species benefit
59
What are the problems with imprinting?
many behaviors are learned an not innate ... for example chicks learn everything about being a bird when they are young like: 1. who to mate with 2. who to follow on migration - Problem for feeding and reintroduction
60
What is the issue with recognition of threats? (with animals in captivity)
Animals held in captivity aren't as afraid of the predators that they should be afraid of. This is a problem in Australia
61
Lack of hunting skill:
predators must learn from experience, how to stalk, bring down prey and kill. Feeding whole animal carcasses encourages stalking, play, pouncing, rolling on skins.
62
How can movement in the environment affect animals?
In the 1980s Golden Lion Tamarinds were introduced back into the wild, but most didn't survive because they weren't used to moving branches so they would loose balance and fall off. Now in zoos they have moving branches so they get that skill.
63
What is an alternative to full reintroduction?
Soft release: release from an enclosure to which they can return for additional food, then you maintain the food until they cease to return, it assumes that hunting is learned.
64
How is stress an issue for animals in zoos?
- It is really an issue in old-style zoos - People are too close, noise is too high, aggressive cage mates - It is recognized by high levels of cortisol in blood or urine
65
What are the two types of stress for the animals in the zoo?
Acute stress: short term stimulation - novelty, excitement, anticipation. Vital in small doses to avoid boredom. Chronic stress: long term and detrimental - depression, helplessness, chronic boredom. Really bad - reduces the immune system, depresses breeding, reduces survival
66
What is the issue with boredom in zoos?
recognized by things like pacing, crib-chewing, rocking, self-harm, feather plucking
67
What are stereotypies?
functionless, repetitive movements not seen in wild conspecifics
68
How do we help create more natural behavior for animals in zoos?
1. Scatter-feeding, puzzle-feeders, ice-blocks of food or blood 2. woodpiles with food underneath 3. forage and browse provisions 4. mixed species exhibits
69
What is contra-freeloading?
because foraging is appetitive, animals get a reward from the process of looking for and finding food
70
Who does better in captivity vs. worse ?
Animals with small home ranges do better in captivity, and animals that have large home ranges to really poorly in captivity.
71
What are the effects of small populations?
1. Danger of in-breeding: there are great precautions to not do this but with rare species it is hard to do this 2. Lack of mate choice: evidence shows that when females have a choice they breed better
72
What is animal personality?
zookeepers get to know animals, and there are differences in personality. - some personalities are favored by the zoo environment more
73
What parts of behavioral ecology does climate change affect?
- Direct affects in CO2 which affects different kinds of animals (leaf-cutter ants) - Phenology: change in timing, migration etc. Range shifts: where animals are, areas that end up
74
What is phenology?
the study of how organisms time their behavior through the year e.g. migration, breeding, hibernation, timed very closely with plant phenology (source of food)
75
What is a range shift?
geographic changes of where a species lives, could shift upward towards the poles. This can cause issues as new species can act like invasive species, or they do really poorly because they aren't' used to the environment - like the food and temp
76
What is anthropomorphism?
considering all animals as if they have the same cognitive experience of the world as we do.
77
What are five widely recognized animal personalities?
1) shy/bold: bold = risk takers, fast to action shy = avoids risk and unfamiliarity 2) exploration avoidance: reaction to novel situations, new habitat, food, object 3) Activity: level of activity 4) Aggressiveness 5) Sociability: reaction to the presence of conspecifics
78
What are Explorers known for (personality)?
They are aggressive, approach novel objects, explore new environments and spend little time in one area
79
What are Non-explorers known for?
Not aggressive, avoid novel objects no foraging patterns, reluctant to explore but spend longer learning about the environment.
80
What is adaptive plasticity?
Personality types are genetically based - but like most traits they may also be influenced by the environment.
81
What is plasticity by itself?
it means that a trait may vary in how strongly it's expressed depending on the circumstance - we should expect some personalities to be constant across different conditions and for some to show adaptive plasticity
82
What are the three orders of intentionality for consciousness?
1. the ability to hold abstract ideas: independent of what you are seeing at the time 2. Self-awareness: (mirror test is a good one) 3. Manipulation and deception: if animals are aware of each others thoughts, they may use this knowledge to manipulate or deceive them
