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.

- What notion is common to each of the species difinitions, morphological, phylogenetic and biological species conceptsarrow_forwardTwo 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_forwardBased on the morphology of Opalina and Volvox, which supports the syncytial hypothesis and colonial hypothesis of animal origin? please explain well and do not copy from googlearrow_forward

What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…arrow_forwardWhat notion is common to morphological, phylogenetic and biological species conceptarrow_forward
