Which of the following demonstrates intraspecific competition |
a ponderosa pine forest thinning as the panderosa trees get larger two sparrows fighting over a nesting site |
|
jackal attacking vultures that are trying to share its animal carcass is an example of |
interspecific interference competition |
|
two leaf bettles chewing on the same leaf is an example of |
intraspecific resource competition |
|
the -3/2 rule refers to |
the relationship between individual plant weight and plant diversity |
|
in the experimental study on competition among plant hoppers, which of the following was observed in he plant hopper population when population densities were high |
lower survivorship |
|
the competitive exclusion principle would say that |
if two species utilize the same resources they cannot live in the same space indefinitely |
|
the introduction of hybrid salt marsh grass Spartina angelica was able to colonize most of the British cost becuase |
it was better competitor in the lower tidal zones which were frequently under water. |
|
how did the Galapagos island drought change the pop structure in finches |
finches with larger beaks survived more because they were able to consume food the other finches could not and so their food source lasted the longest |
|
competition can have ecological effects that change the realized, but not fundamental niche of species. competition can lead to evolutionary changes in a species that can change the species fundamental niche |
TRUE TRUE |
|
which statement is FALSE regarding the study of barnacles along an intertidal exposure gradient |
barnacles that typically live at middle to lower zones are unable to live at upper zones due to competition |
|
Which of the following statements is FALSE regarding the rodent exclusion experiment by Jim Brown in New Mexico |
the removal of the large granivorous rodent increased the pop of the small granivorous and the small insectivorous rodents |
|
two species of finches on the Galapago Island show evidence of character displacement in their beak size where the finches coexist because |
ALL OF THE ABOVE |
|
competition interactions would be |
negative, negative |
|
exploitative interactions would be |
positive, negative |
|
exploitative interactions could include |
a leaf eating beetle on a tree a lion hunting a gazelle |
|
in the study of starlings and the parasite Plagiorhynchus why did starling more often eat isopods that were infected with the parasite |
the infected isopods spent more time in the open where the starling could find them compared to uninfected isopods. |
|
Which of the following is a FALSE statement regarding the interaction of rust fungus and mustard plant |
the presence of the rust fungus causes the mustard to produce flowers containing the spores of the fungus along with the pollen of the plant |
|
the presence of a parasite has been shown to switch which species has the competitive advantage in flour beetles |
true |
|
the data on snowshoe hare and lynx pop dynamics which shows out of phase oscillations since the year 1980 was generated from |
records kept by fur trapping companies. |
|
in Gause's attempts to produce stable predator prey oscillations which trait achieved the desired pattern. |
combining a refuge with immigration from a source population |
|
Select the true statement regarding the factors that contribute to the control of snowshoe hare population |
predators had a negative effect on snowshoe hare populations |
|
Which of the following is NOT a type of refuge |
all of the above |
|
Which of the following is NOT an important plant mutualism |
interactions with herbivores that increase the amount and rate of seeds produced in plants |
|
what benefits do ants confer to their acacia mutualists |
protection from herbivores release from competition with other plants |
|
why don't the ants affect the pollination of acacia trees |
the flowers contain anti-ant chemicals |
|
Which of the following statements is FALSE regarding the plant-mycorrhizae interaction |
he plant gets glucose from the mycorrhizae and the mycorrhizae gets soil nutrients from the plant |
|
theory predicts that mutualism will evolve when |
successful and unsuccessful mutualist combined have higher fitness than non mutualist in the population |
|
the marine mutualism most like the ant acacia mutualism is the |
pistol shrimp and coral reefs |
|
in the human mutualism withhoneguides |
birds stay in sight longer if the honey source is farther away as the distance to the honey source decreases, the distance between stops goes down |
|
community structure include |
number of species relative abundance of species |
|
a guild is best defined as |
a group of organisms living in the same place |
|
the log normal distribution of species abundance shows that |
most species have intermediate abundance there are relatively few rare species |
|
the rank abundance curve of a species with high evenness value would have |
no slope |
|
Which of the following would qualify as factors that affect habitat heterogeneity |
all of the above |
|
increases in habitat heterogeneity would increase diversity by |
all of the above |
|
along a gradient of nutrient availability in the rainforest of Ghana |
there is highest diversity at low nutrient availability |
|
in the study looking at ecotomycorrhizal fungal diversity along a nitrogen gradient created by a fertilizer plant |
there were different species present at high & low nitrogen availability there was high fungal diversity at low nitrogen availability |
|
in the study of the effects of urbanization on species richness, the highest species diversity was seen in the |
golf courses |
|
in the study of the effects of urbanization on species richness, the highest number of native birds were seen in the |
preserves |
|
in the study of the effects of urbanization on species richness the bird communities that were the most similar between Palo Alto, CA and Oxford OH were found in |
office/ appartments |
|
purpose of food webs is |
summarizes all the competitive, exploitative, and mutualistic relationship among species in a community |
|
which of the following statements is FALSE about communities |
a keystone species can provide community structure by it providing large amounts of habitat for species. (such as forest trees) |
|
The study in which chrusomelid beetles benefit from beaver browsing of cottonwoods on the weber river was considered a commensalism because |
the beaver activity was not positively or negatively affected by the beetles activity the beetle benefited from the beaver's activity |
|
apparent competition can occur when |
all of the above |
|
in Roverts Paine's study on food web structure he found |
as the # of species in a community increased, the proportion of predators also increase. removal of the top predator in a community often results in a decrease in species richness. |
