1.1 Observations and questions




All natural observations begin with a question.
At first our curiosity may be satisfied simply
by knowing the species name.
Then we may want to discover what it is doing
and to understand why it is behaving in a
particular way.
For students of behavioural ecology, a whole
host of questions come to mind as they observe.

觀察 a starling bird



Searching in the grass for food
The starling walks along, pausing every now
and then to probe into the ground.
Sometimes it succeeds in finding a prey item,
such as a beetle larva and eventually, when it
has collected several prey, it flies back to the
nest to feed its hungry brood.
行為生態學
10
A whole host of questions

The first set of questions concern the way the
bird feeds.





Why has it chosen that particular place(特定地區)
to forage?
Why is it alone rather than in a flock?
What determines its choice of foraging path?
Does it collect every item of food it encounters or
is it selective for prey type or size:
What influences its decision to stop collecting food
and fly back to feed its chicks:


Another set of questions emerges when we follow the
starling back to the nest.






Why has it chosen this site?
Why this brood size?
How do the two parent starlings come to an agreement over
how much work each puts into offspring care?
Why are the chicks begging so noisily?
Are they each simply signaling their own degree of hunger
or are they competing for food?
What determines how much effort it puts into
reproduction versus it own maintenance, the factors
influencing the timing of its seasonal activities, its
choice of mate, and so on.



Behavioural ecology provides a framework for
answering these kinds of questions.
It combines ideas from evolution, ecology and
behaviour and has emerged from five schools
of thought, developed primarily in the 1960s
and early 1970s.

1.2 Tinbergen’s four questions

Tinbergen(1963) showed that there are four
ways of answering the question ‘why?’ in
biology.




In terms of function (功能)
In terms of causation (cue 因素)
In terms of development (發展)
In terms of evolutionary history (演化歷史)

1.3 Ecology and behaviour

To correlate difference between species in behaviour
with differences in ecological factors (生態因素), such
as habitat, food and predation (棲息地、食物和掠食).



Cullen(1957), a student of Tinbergen, interpreted the reduced
anti-predator behaviour of kittiwake gulls, compared to the
ground-nesting gulls, in relation to their safer nest sites on
steep cliffs.
Winn(1958), linked the reproductive behaviour of 14 species of
darter fish to their ecology.
Wilson (1959), related the colony size and structure of dacetine
ants to their feeding habits.



Crook’s (1964) study of weaver birds.
How differences between species in food and
predator pressure affect a whole host of adaptations,
including nesting dispersion (colonies vs. territories),
feeding behaviour (solitary vs. flock) and mating
systems (monogamy vs. polygamy).

1.4 Economic models of behaviour


The pioneer in the use of mathematical models in
ecology to quantify trade-offs was Robert MacArthur,
who first applied the idea of optimal choice I the
context of foraging behaviour (e.g. MacArthur &
Pianka, 1966; MacArthur, 1972).
Classic early studies include work by Schoener (1971)
and Charnov (1976) on prey choice and patch choice
by foragers and Parker’s(1970) study of copulation
time in the yellow dungfly.

1.5 Evolutionarily stable strategies





Fisher’s (1930) explanation for why parents expend
equal rexource on male and female progeny.
Hamilton’s (1967) analysis of stable sex ratios under
local mate competition.
Parker’s (1970) field study of how male dungflies
distribute themselves across different mating sites.
Fretwell and Lucas (1970), on habitat choice by birds.
Maynard Smith’s (1972, 1982) concept of ESS, is
now widely accepted as the way of analyzing
decision making.

1.6 Kinship, social evolution and
breeding systems


Wynne-Edwards(1962) proposed that social
behaviour was an adaptation for regulating
animal populations.
Many ethologists also used group selection to
explain behaviour.



Individual benefit vs. group benefit
Multiple mating (sperm competition)
DNA fingerprinting

1.7 critical views

1.7.1 Determinism


1.7.2 Panglossianism


Genetic determinism
Gould and Lewontin (1979), The Panglossian
paradigm, referring to Dr. Pangloss, who took the
view that everything was always for the best.
1.7.3 Anthropomorphism

Honest signaling

1.8 Looking ahead


Never prophesy(預言) , especially about the
future.
However, the changes signaled by the new
emphases in the Behavioural Ecology coincide
with a change in the nature of the subject.


A new form of integrated study
With powerful techniques, from gene splicing to
magnetic resonance imaging
