BIO 41- Exam 1 Study Guide With Complete
Questions And Answers
1.Briefly describe how our species started to appreciate
the biodiversity of the planet (in a geographical and historical
context)?: Direct observation, geographical exploration, explanations
through religious texts.
2.Early naturalists tended to gather biodiversity information
in a slightly differ- ent manner compared to modern biologists.
Explain.: Naturalists in history mostly gathered biodiversity information
through direct observation, sketches, specimens, etc. Modern day biologists use more
modern technology and have more information on evolution and how ditterent species
are related in the animal kingdom
3.Compare and contrast the difference between taking
digital photographs of an organism versus
drawing/sketching one in the field.: Digital photographs are
exact representations of the species depicted, but sometimes are diflcult to capture in
nature. Sketches are more
Personalized and are often used more in bird call books and so on. Both have ditterent
advantages and disadvantages.
Explain the concept of binomial nomenclature.: Linnaeus- Every
4.
species has a unique name composed of 2 parts: the genus and the species
,epithet.
Ex. Homo sapien
5.What is a species? Define the biological species concept.: A
group of living organisms consisting of similar individuals capable of
exchanging genes or interbreeding.
6.How did Carl von Linne (Linneaus) contribute to the field
of biology?: "Systema Naturae" 1738 The manuscript described a new
system for classifying plants.
7.What are the different taxonomic levels (in order
from the largest to the smallest taxon)?: Domain, kingdom,
phylum, class, order, family, genus, species
(Dear King Philip Come Over For Good Spaghetti)
What is the purpose of taxonomy? How is it used in
8.
biology?: The science of defining groups of biological organisms on the
basis of shared characteristics and giving names to those groups.
How many species have been described (i.e. The total
9.
number of species named and categorized)?: Approximately
1.4 million
10. Which is the most dominating taxon within the animal
,kingdom in terms of species diversity (making up
approximately 25% of all known species)?: Coleoptera
(Beetles)
The phylum Arthropoda [meaning "joint-footed"] is the
11.
largest described taxon on the planet in terms of species
diversity. The phylum includes all types of insects,
crustaceans, spiders, millipedes and centipedes. What is
percentage of the phylum Arthropoda of all known animal
species?: Approx 84% in this phylum
, Study the diagram of all known organisms below. What
12.
percentage is made up of animal species? What percentage
is made up of insect species?: About 20% are animals and about
53.1% are insects.
13.Terry Erwin changed our concept of the number of
species that inhabit the planet. Briefly describe his
experiment and how he estimated the number of insect
species in the tropics.: Erwin fogged trees of a specific species and studied
the species of insect he found. He noticed each tree had insect species specific to That
tree, as well as many insects that were just visiting. By figuring out how many species
were indigenous to each tree (on average), and calculating how many ditterent species
of tree were around the world, he was able to figure out how many ditterent species of insect
there were on the planet! (lots of math)
How many insect species exist in the tropical rain
14.
forests according to Terry Erwins data?: He observed 1,100 types of
beetles and 160 of them were specialized.
How was Erwin's paper received in the scientific
15.
community? Explain!: His idea of 30 million insect species was not
accepted worldwide because now we say so for 1.8 million species are found.
