What is Ecology - correct answer The study of interactions between organisms
and their environment
Environment - correct answer all factors outside the organism that influence it
(abiotic or biotic)
To explain/understand ecological processes, we are most interested in _______,
_______, and _________ - correct answer birth, death, and migration processes
Two classes of explanation - correct answer 1- Proximal - patterns explained by
the present (short-term) environment
2- Ultimate - patterns explained by the past environment
heuristic - correct answer principle or rule to guide interpretation
ecologic hierarchy - correct answer individuals
populations
community
evolutionary ecology - correct answer study of individuals as the units of
evolution
physiological ecology - correct answer study of individual responses to the
abiotic environment
behavioural ecology - correct answer study of individual responses to the biotic
environment
conservation ecology - correct answer blend of evolution, population,
community, and ecosystem ecology to conserve biodiversity (applied to
conservation issues)
population's role in evolution - correct answer where evolutionary changes are
revealed
Homozygote - correct answer an individual that has the same alleles at a
particular locus pair (AA, aa)
Heterozygote - correct answer an individual that has different alleles at a
particular locus pair (Aa)
,BIOL 2300 - Ecology - Final
Mendelian Inheritance - correct answer principle stating that the breeding of two
individuals results in multiple combinations of alleles
genetic recombination - correct answer all possible allele combinations from
random mating of any combination of individuals
Genotype - correct answer genetic characteristics of an individual
Phenotype - correct answer outward expression of genes in the
appearance/behaviour of an individual
Phenotype Plasticity - correct answer the ability of a genotype to alter its
phenotypic expression under different environmental conditions
Phenotypic variation can be expressed as... (2) - correct answer Discrete or
Continuous
Discrete phenotypic variation (what is it, example) - correct answer alternate
forms of a gene, social insects' hierarchy (bees, ants).
two types of larvae hatch with essentially the same genetic material
Continuous phenotypic variation (what is it, example) - correct answer
continuously varying phenotypes, Daphnia (pigmentation responds to varying UV
radiation
Daphnia (example of ... phenotypic variation, what is it) - correct answer example
of continuous phenotypic variation
pigmentation of an individual responds to varying UV radiation
transparent when avoiding predators, highly pigmented when avoiding effects of
harmful UV radiation
How do organisms exhibit phenotypic plasticity in their reaction norms? - correct
answer by adjusting their phenotype in response to varying environmental factors
A heterozygote - correct answer is an individual that has different alleles at a
particular locus on a pair of chromosomes
Species richness - correct answer diversity of species present in a community
, BIOL 2300 - Ecology - Final
species evenness - correct answer distribution of individuals among species in a
community
selective harvesting of small sized fish will result in what type of selection -
correct answer directional selection
How are fundamental niches and realized niches different - correct answer
fundamental niche - entire range of environmental conditions
realized niche - actual set of conditions the species occupies in the presence of
competitors
What are the main factors used to explain ecological processes - correct answer
birth, death, migration which influence their numbers and where they are located
to evaluate hypothesis, scientists may - correct answer conduct observational
studies
collect measurable features of the natural world
conduct controlled or manipulated studies
examine the fit of natural processes to mathematical models
the most important factor influencing the evolution of organisms living in a
terrestrial environment is - correct answer maintaining water balance
What is our solution to control Sclerotinia? - correct answer reduce chemical
input in the agro-ecological environment
develop species specific protection
translational applications
conservation ecology specifically focuses on - correct answer a blend of
evolution, population, community, and ecosystem ecology
Why do we need to protect crops based on Mark Belmonte's lecture? - correct
answer pests and pathogens cause 30% loss in crop yield
Human activities (can/cannot) cause species to evolve - correct answer can
Regarding sclerotinia infecting and destroying canola
