You can use plants grown in pots in a growth chamber to investigate many ecological and evolutionary research questions. Identify an interesting ecological or evolutionary research question, then design an experiment to address this question using a plant system. To come up with your research question, think of questions related to topics covered in lecture. The following questions are very general, but might give you some ideas as you develop your own, more specific, question.• Which species in a group of species is the best intraspecific competitor?• Which species in a group of species is the best interspecific competitor? • Is the best intraspecific competitor also the best interspecific competitor?• Does competitive exclusion occur between two species with similar ecological niches?• Does the outcome of interspecific competition change in different environments, or is the best competitor always the best competitor under all environmental conditions?• Similar to the question above –…
A genome duplication event, creating a tetraploid plant from a diploid parent plant, can sometimes result in the creation of a new species. This type of speciation is called
allopatric
adaptive radiation
sympatric
gradual speciation
Which of the following is an example of a postzygotic barrier?
Hybrid offspring of two species of jimsonweeds always die before reproducing
One plant lives on acid soil, the other on alkaline soil.
Two species of leopard frogs have different mating calls
Mallard and pintail ducks mate at different times of the year
Pollen of one species of tobacco cannot fertilize a different species of tobacco.
Which of the following is FALSE regarding phylogenetic trees?
1) The branch lengths on the tree are scaled to molecular (DNA) changes and/or time.
2)Phylogenetic trees have shown us that there is much more bacterial diversity compared to eukaryotes.
3) Phylogenetic trees show the evolutionary relatedness of different organisms.
4). The branch lengths on the tree depict abiotic and biotic factors affecting speciation.

- Two biologists are arguing at a conference. One says that the Biological Species Concept (BSC) is superior. Her colleague argues that a different species concept is needed. Which of the following claims of the biologist are true and which are false? 1. The BSC potentially would work for all multicellular organisms. 2. A Morphological Species Concept would work better for cryptic species than the BSC. 3. If two populations of snails are separated by a huge distance, they cannot mate. This means the BSC cannot apply to them.arrow_forwardWhole genome duplication is important in speciation by hybridization because: It creates homologous pairs of chromosomes It allows plants to self fertilize Tetraploids can hybridize with other species better than diploids can It reduces the fitness of intermediate phenotypes It increases the rate of drift in small populationsarrow_forwardOrthologous genes are duplicated genes as an accompaniment to speciation. They are duplicated genes that have lost their function. The 1st statement is True and the 2nd statement is False. The 1st statement is False and the 2nd statement is True. Both Staments are True. Both statements are False.arrow_forward

It refers to the relationship between ancestors and descendants and relationships among descendant taxa. It shows the lineage of taxa which can be summarized in a branching diagram called a phylogenetic tree.1.

- How to interpret this phylogenetic tree (Maximum Likelihood)?arrow_forwardFor the the organisms Orchard Spider and Allies What is the geographic distribution of each species? Is it native or invasive? indicate where it is native and if it is not native, indicate where its native range is. Write a short description of each organisms’ life history (no more than three sentences for each one). Life history facts include diet, behavior, breeding, habitat etc. After reading about the life history of the three species you are focusing on it should be relatively simple to isolate what you find most interesting about them. Write a short description about what you find most interesting about all three species you are focusing on (no more than four sentences for each species).arrow_forwardAt the end of the first full paragraph on p. 703, Lauder and colleagues point out that closely related species can differ for two very different reasons. What are these two causes of species differences? I'm confused about what those two reasons are as I can't find the reasons.arrow_forward
- Hybridization was not originally recognized as a mechanism of speciation by either Darwin or the researchers of the "new synthesis". However, today there are many examples of species that have originated through hybridization. What is the best explanation for why we have so many examples of species originating through hybridization? Hybridization is more likely to occur in regions where scientists have put in more effort studying speciation Hybridization has been carried out frequently by farmers attempting to produce new, better species to grow Hybridization occurs fairly regularly, and when it leads to new species only takes a few generations, which is fast enough for researchers to see fairly easily Hybridization is fairly easy to study in captivityarrow_forwardBelow are phylogenetic trees depicting the relationships among four species, A, B, C, and D.
