DETAILED ANSWERS
Acreage Reporting Date - (ANSWER)The deadline for providing the insurer with an acreage
report, which is used to determine the amount of coverage needed and the premium
charged for a particular crop.
Cian purchased a house with money loaned to him by Keithly Mortgage Co. (KMC). Cian
obtained a homeowner policy from Melfor Insurance—containing a standard mortgage
clause—which covered the house for damage dueWhat is a population? -
(ANSWER)Individuals of the same species that interact on a regular basis
What is an individual? - (ANSWER)can be a single organisms or a colony/group
fan coral: an individual but also a colony of polyps
Genet and Ramet - (ANSWER)Genet: group of clonal individuals
Ramet: individuals within the genet
Population Characteristics - (ANSWER)Geographic range - distribution
Dispersion
Density
Size
Age structure
,Etc.
Geographic Range - (ANSWER)The distribution of a population in space
Within the range the distribution is still patchy
Abundance varies throughout the range as well
Depends on distance from which you're looking:
"Nothing is straightforward in ecology" - It could be Lynn, you just choose violence
Why is a population found where it is? Why not in other places? - (ANSWER)1. Ask if
habitat is correct?
2. Biotic interactions
3. Dispersal ability: can the species even get there? (No shit, if you can't fly or swim you're
not getting to an island)
4. behavior: preference for particular habitat
5. history
Use niche models to predict current and future distributions - (ANSWER)Can use climate
models to predict future environmental conditions and create new niche model to predict
future distribution
Need to keep species and new location alive to protect a species
,Abundance and Density - (ANSWER)Define the size of the population
How many individuals and how tightly packed are they
Estimates are very dependent on dispersion pattern
Dispersion patterns - (ANSWER)The pattern in which you find individuals
What you see may depend on the distance from which you're looking
Affected by resources, dispersal abilities, behavior
3 patterns
Uniform dispersion - (ANSWER)Evenly spaced individuals
Usually direct interactions among individuals
Usually competition: acacia trees competing for water so roots well developed (can't
survive if you settle between the developed trees)
Random dispersal - (ANSWER)Dandelions in a field; ferns on forest floor
Lack of predictable pattern
, Absence of attraction or aggression (Necessary resources evenly distributed (no need to
compete)
Not very common in nature
Clumped/clustered dispersal - (ANSWER)Organisms are found in groups
most common in nature
Patchiness of resources;
Aggression or attraction
Aggression in form of predation (group safer) or in form of competition and pushed
towards resources
ex.) schools of fish
Quadrat estimation - (ANSWER)Make a square space of known size; count individuals in
quadrat (again...)
Take average of all quadrats
Good estimate if species distribution is even (clumped messes up average)
Not good for moving/migrating species (could count individual twice)
