Expected Learning Expectations
At the end of this presentation, a fully engaged student should be able to
1) Name at least two ways warmer temperatures have affected animal mating behavior
2) Define “double brooding” and discuss what must happen in order for this to occur
3) Discuss examples of birds are positively affected by global warming, and what kind are harmed
4) Discuss how is warmer temperatures affecting the sex of Loggerhead Sea Turtle hatchlings
5) Discuss why Antarctic seabirds arriving and laying their eggs earlier or later than their relatives
6) Explain why are the Netherland Great Tits not as successful as their British counterparts in responding to global warming

Here are my comments on Emily's Presentation.
ReplyDeleteI thought that you did a great job on your presentation. It was clear that you were super-well prepared, both in terms of the research about the topic and about the presentation.
Presentation- I thought that your presentation was well organized. You did a good job of introducing the basics of the topic which helped to provide a good base for your presentation. You did a good job of focusing this particular talk to your audience (for example, because you knew that the class had spent a lot of time thinking about climate change you didn't need to go into the depth you would if you were addressing a different audience). The remainder of your talk was organized into appropriate sections.
I thought that your presentation style of very good. I could tell you were a little nervous (not too surprising). As you got more comfortable later on in the talk, you got better at just talking to the audience rather than focusing so much on your note cards. I thought that your pacing was good (not too fast or too slow) and in general I thought that your slides were good (especially the slides that showed pictures of the organisms that you were talking about. Keep practicing on oral presentations and I think that you will become a very good speaker.
Material- After hearing your presentation I might change the title of your presentation to something like "Effects of climate change on reproductive success". The term "mating" generally means "the male copulating with the female to fertilize eggs". Although climate change can affect "mating" much of your talk focused on how climate change affects other attributes of reproductive success such as the number of clutches a female can produce per season, the survival of the offspring, the sex ratio of offspring etc.
The critical organizational slide in your presentation is - Factors of Global Warming that affect Mating Behavior. Maybe you could reorganize this slide like-
Climate change can affect reproductive success by
- altering breeding times
- affecting resource availability
- influencing migration patterns
- habitat destruction
- genetic changes
I thought that the body of your talk did a good job addressing these issues. I thought it was great to go through so many examples of how climate change could affect reproductive success. Perhaps you could have spent a bit more time providing a brief introduction to the species you were talking about (for example, I know something about the basic biology of great tits and common murres, but did everyone else?). I was interested in each of the examples that you presented and that they worked well together to show how complicated this area was.
Although you did have a nice general "save the world" sort of conclusion, I think that you could have included a more specific "ecology conclusion". I don't know exactly what your conclusion should be, but it would be something like-
Conclusions
- Climate change can affect the reproductive success of organisms in a number of ways
- Sometimes this change increases reproductive success, but generally these effects are harmful (is this true)?
- Often these effects are indirect (involve other species)- often food supply
