The three factors that influence climate are
What is variation in light intensity, the angle of the earth, and variation in local conditions?
An organism that feeds on other organisms but does not influence their abundance is called.
What is a Detritivore?
when a species evolves due to interactions with another species
co-evolution
Under the probable conditions of Earth's early atmosphere, this experiment led scientist to determine that it would have taken a week to form all necessary organic molecules for life.
What is Miller-Urey?
The ribosome is a trait of
all life forms (6 traits shared by all life; Lecture 11, slide 29)
An ecologist would observe the air at the center of a Hadley cell behaving like this.
What is rising?
Then expanding, cooling, and falling as rain
A fungus on a tree secretes toxins that harm the tree, but the fungus remains unaffected. This symbiosis is called...
What is Amensalism?
niche conservatism
Individuals with a gene that leads to the expression of sickle cell anemia and malaria resistance display...
What is Pleiotropy?
The state of fungi that is neither haploid or diploid in its sexual reproductive cycle
dikaryotic (n+n) **plasmogamy and Karyogamy (Lecture 17, slide 13)
This biome experiences less little rainfall, average temperatures below freezing, and permafrost that prevents deep-root vegetation.
What is Tundra?
Two frog species live in the same habitat, however one of the species remains dormant during the daytime as the other is active and searching for food. The same species then becomes active at nighttime searching for food while the other remains dormant. This is an example of
What is Temporal Partitioning?
the number of species present in a given area
species richness
Two phylogenies are drawn to show the evolutionary relationships between the same species. One phylogeny presents the least individual evolutionary events that lead to each taxon. A phylogeny with the simplest explanation is known to have...
What is Parsimony?
The presence of peptidoglycan guarantees we are looking at
a bacteria (archaea will NEVER have peptidoglycan, Lecture 12)
During this kind of year, warm pacific water moves eastward and lead to the northern hemisphere having a warmer and drier climate.
this type of hunting involves the least amount of energy. a predator sits and waits for prey to arrive and pounces on them when they are in range
Ambush hunting
when is an islands S* the highest
close, large islands
Ambulocetus natans and Archaeopteryx are an example of this type of species that developed on Darwin's hypothesis of evolution.
What is "Missing Link"?
What is Intermediate forms?
During the dissection of an unidentified organism it is found to possess distinctive organ systems. With further analysis it is also confirmed to have nerve nets
Cnidarians (Lecture 18, slide 11)
A species of lizard migrates to an island where there are abundant resources. The lizard does not need to compete with any other species for the resources and survives with many offspring. This species is using what niche?
What is fundamental and realized niche?
This form of mimicry is when a non-poisonous organism develops the colors of a poisonous one to deter predators
batesian mimics
describe climatic stability hypothesis
In population of birds, females mate more often with males who have brighter feather colors. This trait protected them from predators who thought they were poisonous but now they attract predators as they make them more obvious. This is an example of...
What is Runaway Selection (Ghost of Selection Past)?
The defining difference between homosporous and heterosporous life cycles
homosporous cycles have generic gametophyte, heterosporous have specific male and female gametophytes (Lecture 15, slides 4&5)
