study of the processes responsible for the variability of
population abundance.
In

Question 5

Look at lect 8 slide 41 pop dynamic

Answer 5

look at slide 42 pop dynamic

Question 6

what is Maximum

sustainable yield

Answer 6

is theoretically, the largest yield
(or catch) that can be taken from a species’ stock over an indefinite
period. MSY aims to maintain the population size at the point of
maximum growth rate by harvesting the individuals that would
normally be added to the population, allowing the population to
continue to be productive indefinitely.

host and at the host’s expense, and which sooner or later
kills it

Question 11

How can a parasite Increase host’s susceptibility to predation

Answer 11

Directly:
by changing their behavior
Indirectly: by making them weak or sick

die at
equal rates,
regardless of age.
2-Juvenile
survival is
high and most
mortality occurs
among older
individuals.
3-Individuals
die at a
high rate as
juveniles and then
at much lower
rates later in life.

e nv i r o n m e n t

Question 18

What is the difference btw exponential and logistic growth

Answer 18

in exponential grwoth the per capita growth rate (r) doesn’t change even if the pop gets very large whereas in the logistic growth the per capita growth rate (r) get smaller as the po approaches its max size (carrying capacity)

Question 19

what is Intraspecific

competition

Answer 19

Phenomena
by which each individual influence s and
is influenced (negatively) by other individuals in the
population.

Question 20

What is a scramble vs constest competition type

Answer 20

In scramble competion everyone as the resource whereas in the contest interference occur when an ind take the contro of the resource.

Question 21

look at lect 8 slide 29

Answer 21

look at lect 8 slide 30

Question 22

what is Interspecific

competition

Answer 22

Effect of a species on the fitness
of another species (fitness different when they are together vs
alone).

Question 23

what are the type of interspecific competition

Answer 23

Direct (e.g. a fight
between two predators)
•
Indirect (e.g. two plants
competing for water)

Question 24

define Stochastic

Models

Answer 24

Stochastic
models, unlike deterministic models, allow unforeseen
or unexplained events to express themselves and influence the
predictions of population dynamics models.

Question 25

define Monte

Carlo simulation

Answer 25

The repeated estimation of a parameter of population dynamics models (r, No, a11, b13, etc.) implies obtaining several results. E.g. 100 experiments aimed at stimating “ would result in 100 estimates of “

GPS logger, satellite transmitter, radio transmitter, geolocator, accelerometer, depth recorder, heart rate recorder

Question 27

What are the rule for using biologging

Answer 27

All tag have effect, handling mau be as imp as taging, Tag placement and streamlining is critical,Implant tags, Use smaller tags, Tag older, higher quality individuals, No X% rule is universally applicable
