What is parthenogenesis?
Producing offspring without fertilization.
|
What is an increase in chemical nutrients (N & P) in an ecosystem that results in an
increase in primary productivity (plant growth)?
Eutrophication
|
What is clumped distribution?
The populations of most species exhibit this type of distribution.
|

What is 13?
This is the value of the gross reproductive rate in the following table:
Age class x lx bx 0 1.0 1.0 1 0.5 4.0 2 0.5 4.0 3 0.5 4.0 4 0.5 0. |

What are allogenic factors?
Environmental changes that are a
feature of the physical environment. |
What is a transition zone between two different communities or ecosystems?
Ecotone
|
What are
• Equal chance of capture for all • Ratio of marked to unmarked constant over time • Marked individuals distribute themselves at random in population • Marks are not lost • No emigration & no immigration • No mortality or reproduction
These are the six assumptions that must be made in mark-recapture exercises.

What is a type II functional response & handling time and satiation?
The following graph exhibits this type of response with the asymptote caused by ______ & _______.

What is the phylogeny of a parasite or pathogen parallels that of its host?
This is Farnholtz’s Rule.
|
|
What is resilience?
Speed at which a disturbed system moves back
to its original state |
What is the moisture level at which plants cannot extract water?
Wilting Point
|
What are?
I. Highly specialized & obligatory II. Casual & facultative III. Widespread coevolution between/among taxa
These are the three categories of mutualistic relationships.
|
What is red?
The _____ color line in the following graph exhibits a type III survivorship curve and is representative of plants.

What is climate change?
This is the cause of mosquitoes moving north and with them the threat of arboviruses to humans.
|
|
What is amensalism?
An association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected (-/0)
|
What is the change in the physiology or form of an organism in response to
changes in environmental conditions?
Acclimatization
|
What are mites, viruses, bacteria, genetics, poor nutrition, habitat loss & pesticides?
These are the reasons for honey bee colony collapse disorder discussed in lecture.
|
What is negative...deterministic?
The following graph shows this type of correlation and is therefore ______.
View Image |
What are?
1. Transport - surviving the trip 2. Establishment - developing a self-sustaining population 3. Spread - dispersing and expanding range 4. Impact - interacting with native & human made ecosystems
These are the stages of invasion by an invasive species.
|
|
What is depensatory?
This is the effect of predators,pathogens, or parasites on a prey or host population that results in natural enemies eliminating individuals, but ultimately the target population is increased.
|
What is the replacement of one community
type by another (seral stages) often progressing to a stable terminal (climax) community? Primary Succession = site previously unoccupied Secondary Succession= site previously occupied
Succession and the types of.
|
What are endomycorrhize?
They increase the surface area of roots and aid in uptake of nutrients and water, and are known to form an association with more than 70% of all plant species.
|
What are the Pinta and Marchena islands?
In the following diagram this is/these are the island/islands on which there is evidence for stabilizing selection in the beak size of G. fortis? (Note that island names are above the histograms)

What is zero?
On average a male honey bee shares this percentage of his genes with his father.
|
|
What is competitive release?
This concept explains the success of introduced Mediterranean grasses because of a lack of competitors in California grasslands, resulting in some having as low as 8% native species.
