Individual Assessment: Using what you’ve learned so far, come up with a model to explain this new phenomenon. Be sure to include all key components and interactions from your “Gotta Have It” checklist.
We can help our community fight (or slow) the increasing frequency of antibiotic resistant bacterial infections by communicating a more effective message (than the CDC) for why people should follow CDC recommendations regarding antibiotic use.
We identified characteristics we wanted in a new case to help us evaluate whether the interactions and outcomes of our model for how bacteria populations can be used to explain changes observed in other populations of organisms.
You will use Google maps to continue to investigate the two different environments that you were introduced to in the juncos case you are studying in class. This page shows you how to use the map view, satellite view, and street view options for exploring UCSD. Record your observations for this environment on this page. The back page provides the same for Mt. Laguna.
Analyze the data about the juncos, and use it on the next page to determine if it meets some of the criteria for the case we wanted to investigate.
There are measurable differences in the tail length, wing length, and the amount of white in tail feathers, found between individuals within each population and in the distribution of variations found between populations.
Develop an investigation protocol to determine differences with UCSD Juncos and the Mountain Junco population.
Follow all procedures A through C to setup investigation protocol to examine body differences between UCSD Juncos and Mountain Juncos,
Graphs displaying the amount of white (%) in tail feathers of campus, wintering, and Laguna Mountain juncos.
From 1998 to 2002, Assistant Professor, Ecology and Evolutionary Biology, Pamela J. Yeh, banded, measured, and monitored individual juncos breeding in the campus population. A total of 298 adult birds were measured over the five years. Since 2000, about 95% of adult birds in the population have been uniquely color-banded, so that nearly every individual in the population can be recognized and tracked. NOTE: Video link on this lesson.
Mean morphology of wing and tail size among birds from University of California at San Diego (UCSD) and the neighboring Laguna Mountains.
Many trait variations seen in birds, like feather colors, feather patterns, and limb proportions are the result of the combinations of alleles that were inherited. These provide instructions to the cells of the organism about what substances (proteins) to produce or not produce.
What sort of measurements would someone need to take to determine if one bird behaves differently (more bold) around people than another bird?
